Babies who are slow to gain weight in the first months of their lives generally catch up to their peers by age 13,a large UK study shows, Researchers said the results would make parents whose babies fail to put on weight quickly less worried.
The researchers looked at data from ,11,499 children who took part in a large study, It showed that 507 who were slow to gain weight in the first eight weeks of life recovered fairly quickly and had almost caught up by age 2. Another group of 480 who were slow to gain between eight weeks and nine months continued to put on weight slowly until they were seven years ,but then had a sudden increase and caught up by age 13, The different pattems of recovery between the two groups were likely due to different reasons for slow weight gain ,the researchers said, All the children were still lighter and shorter than their peers by the time they were teenagers ,but within the normal range.
The findings highlight the importance of monitoring a baby’s weight and height gain during the first few weeks and months ,but not creating anxiety with parents of slow-growing babies, said the study leader Prof Alan Emond from the University of Bristol.
“In the past, a lot of parents have been caused unnecessary anxiety by heaith professionals and this is a positive and reassuring message.”He said in many cases of slow growth where children do not follow the standard’curve’(曲線)it is just because they are following their genetic potential.
Dr Simon Newell, vice-president of the Royal College of Paediatrics and Child Health, said he broadly agreed with the concluslons of the researchers but stressed that poor weight gain was something that needed to be monitored closely, “I would encourage parents to use growth charts but if measurements show your baby is smaller than averager it may be completely normal, ”he said.
【小題1】What can we know from the findings of the research?

A.All the cases of slow weight gain in the first months of the babies’ lives are caused by the same reason
B.Slow-growing babies will have the same height and weight with their peers by age13
C.Many cases of children whose growth don’t meet the growing standard curve cannot be treated as abnormal
D.The findings won’t cause parents’ anxiety so monitoring a baby’s growth from his/her birth is unnecessary
【小題2】Which of the following statements is true according to the passage?
A.It’s important to monitor a baby’s weight and height gain for new parents
B.New parents should feel anxious about their baby’s weight and height gain
C.Researches still couldn’t find the reasons for slow weight gain
D.All the children’s weight and height became normal by age 13
【小題3】What does the underlined word in the fourth paragraph mean?
A.Making sure something is certain to be true
B.Making someone calmer and less anxious
C.Confirming something is to happen again
D.Being sure that someone can be attracted
【小題4】Which of the statements would Dr Simon Newell agree to?
A.To some degree, growth charts can help parents monitor their babies’ weight gain
B.It’s abnormal for babies are smaller than average
C.He agreed with the researchers completely
D.Babies’ weight gain can only be monitored and measured by using growth charts.
【小題5】The writer wrote this passage in order to        
A.tell us how to help babies grow faster
B.explain why babies are gain weight slowly
C.report on the findings of a research
D.reduce the anxiety of some parents

About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
【小題1】The passage is mainly about _____________.

A.color and its surprising effects.
B.women being luckier than men
C.danger caused by color blindness
D.color blindness
【小題2】According to the passage, with the help of the “cones”, we can_______________.
A.tell different shapesB.see in a weak light
C.kill mosquitoesD.tell orange from yellow
【小題3】Why do some people say it is safer to be driven by women?
A.Women are more careful.
B.There are fewer color-blind women
C.Women are fonder of driving than men.
D.Women are weaker but quicker in thinking.
【小題4】Which of the statements about the color- blind is true?
A.Not all of them have the same problem in recognizing color.
B.None of them can see deep red.
C.None of them can tell the difference between blue and green.
D.All of them see everything in shades of green.
【小題5】We can attract and kill mosquitoes by using a _____________.
A.red lightB.yellow lightC.blue lightD.green light

A regular drop in the sun’s radiation(輻射) can cause unusually cold winters in parts of North America and Europe, scientists say, a finding that could improve long-range forecasts and help countries prepare for snowstorms.
Scientists have known for a long time that the sun has an 11-year cycle during which radiation measured by sunspots on the surface reaches a peak then falls. But explaining a clear connection to weather is harder.
“Our research confirms the observed connection between solar change and regional winter climate,” lead author Sarah Ineson of the UK Met Office told the reporters in an email. The study was published in the magazine Nature Geoscience on Monday.
The researchers found that the reducing of ultraviolet(UV,紫外線) radiation from the sun can affect high-altitude wind patterns in the Northern Hemisphere(半球), causing cold winters.
“While UV levels won’t tell us what the day-to-day weather will do, they show us the bright future of improved forecasts for winter conditions for months and even years ahead. These forecasts play an important role in long-term possibility planning,” Ineson, a climate scientist, said.
Ineson and colleagues from Imperial College London and the University of Oxford used satellite data that more accurately(精確的) measures UV radiation from the sun and found a much greater change than previously thought.
They found that in years of low activity, unusually cold air forms high in the atmosphere over the tropics. This causes a redistribution(重新分配) of heat in the atmosphere, making easterly winds that bring freezing weather and snowstorms to northern Europe and the United States and milder weather to Canada and the Mediterranean.
When solar UV radiation is stronger, the opposite occurs.
More study was needed, though. A key uncertainty in the experiment lay in the satellite data used, because it covers only a few years. “So questions remain concerning both accuracy(精確) and also applicability to other solar cycles,” she said.
【小題1】The new finding claims cold winters in the North Hemisphere can be caused by ______.

A.a(chǎn) sharp rise in the amount of sunspots
B.a(chǎn) drop in the sun’s UV radiation
C.a(chǎn) complex computer model simulation
D.a(chǎn) clear link between the sun and the earth
【小題2】 It has long been known by scientists that ______.
A.UV radiation can affect high-altitude wind patterns
B.there’s a clear connection between the sun’s activity and weather
C.the sun’s radiation reaches a peak every eleven years
D.they can predict day-to-day weather conditions from UV levels
【小題3】What will happen if the sun turns into years of high activity according to the finding?
A.Canada and the Mediterranean will have milder weather.
B.The whole Northern Hemisphere will suffer from extreme winter days.
C.Freezing cold weather will appear in northern Europe.
D.Burning hot weather will appear in the United States.
【小題4】 It can be inferred from the passage that ______.
A.researchers have analyzed the data collected in eleven years
B.long-term weather conditions can be accurately predicted depending on UV levels
C.the research doesn’t seem correct and true enough due to limited satellite data used
D.climate scientists have just begun their research in severe weather forecast

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affect sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels(分貝)measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
【小題1】According to the passage, which of the following is increasingly dangerous to sea creatures?

A.The man-made noises.
B.The noises made by themselves.
C.The sound of earthquakes.
D.The sound of the ice-breaking.
【小題2】As to the influence of noises on whales, which of the following statements is true?
A.They are deaf to noises.
B.Noises at a certain level may hurt them.
C.They are easily confused by noises.
D.Noises will limit their ability to reproduce.
【小題3】 We can know from the passage that many scientists think that the noise limit of one hundred twenty decibels would______.
A.prevent them from doing their research work
B.benefit them a lot in their research work
C.do good to their health
D.increase the industrial output
【小題4】According to the passage, what will scientists most probably do in the future?
A.They will try their best to decrease noise.
B.They will work hard to cut down noise pollution.
C.They will study the effect of different noises.
D.They will protect animals from harmful noises.

Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland(瑞士)and China, built by the government(政府)to help some of the people live during a great war. 
But will people change if they live under the ground for a long time?For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals(化學(xué)制劑)in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone?
【小題1】People will live under the ground because _________. 

A.it’s neither hot nor cold there
B.they’ll be afraid of the war
C.there’ll be less space on the ground
D.they’ll make their life comfortable
【小題2】Some countries try to build some places under the ground so that people will be able to live there _____.
A.when summer comes
B.when a war breaks out
C.because they think it’ll be safer for them
D.when they’re fed up with the life on the land
【小題3】_________, so people who will live there won’t go blind. 
A.There’ll be enough light under the ground
B.It’ll be easy to go upstairs
C.Glasses will be sold under the ground
D.Medicine will be supplied for free
【小題4】People will lose some senses under the ground because _______.
A.the world are polluted
B.it’s dark there
C.the air is dirty and there are a lot of chemicals in their food
D.they can’t grow their own food in the sun

Man, a land animal. But he is also closely tied to the sea. Throughout history the sea has served the needs of man. The sea has provided man with food and a convenient way to travel to many parts of the world. Today, nearly two-thirds of the world’s population live within 80 kilometers of the sea coast.
In the modern technological world, the sea offers many resources to help mankind survive. Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many of man’s needs.
The list of riches of the sea yet to be developed by man’s technology is big. Oil and gas explorations have been carried out for nearly 30 years. Valuable amounts of minerals exist on the ocean floor ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish (貝類動物) is an ancient skill practised in the past mainly by Oriental people, including people in China.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy.
Technology is enabling man to explore ever more deeply under the sea. The development of strong, new materials has made this possible.
The technology to harvest the sea continues to improve. Experts believe that by the year 2020 the problems that prevent us from exploiting(開發(fā)) fully the food, minerals, and energy sources of the sea will be largely solved.
【小題1】Valuable amounts of minerals are ______.

A.in the ocean waterB.in the warm ocean water
C.on the sea coastD.on the ocean floor
【小題2】We can conclude from this passage that ______.
A.the sea resources have largely been used up
B.the sea, in the broad sense, has not yet been developed
C.the problems that prevent us from using the food, minerals, and energy sources of the sea have already been solved.
D.by the year 2020 , the technology will be good enough to exploit all the sea resources
【小題3】The underlined words “Oriental people” in the fourth paragraph probably mean ______.
A.the people in AsiaB.African people
C.European peopleD.American people
【小題4】The best title for this passage is ______.
A.Sea HarvestB.Sea Food
C.Technology for Exploiting the SeaD.Man and the Sea

China needs to set absolute restrictions on greenhouse gas emissions(釋放) if it is to fulfill its aim to set up a carbon market over the next five years, a cabinet office think tank said in a paper.
“It is only under an absolute emissions cap that carbon emission permits will become a scarce resource and possess the qualities of a commodity,” the State Council?s Development and Research Center said in a paper in Seeking Truth, a magazine published by the ruling party.
China has traditionally baulked(猶豫) at the idea of emissions caps either on a regional basis or for industrial sectors, invoking a key Kyoto protocol principle that puts most of the burden of cutting green-house gases on developed countries.
China, the world ‘s biggest emitter of greenhouse gases, has also been under external pressure to make stronger commitments in the battle against global warming .The country has been the biggest beneficiary(受益人) of the Clean Development Mechanism, a UN-backed scheme that allows industrialized countries to meet their CO2 reduction targets by purchasing certified emission reductions or CERs from low-carbon projects launched in developing nations.
However, the European Union, the biggest buyer of CERs, has said it will not accept CERs generated by Chinese projects once the first phase of its Emissions Trading Scheme ends in 2012, though projects already registered will remain valid.
【小題1】 What does China hope to do in the next five years?

A.to cut its emissions by 45%
B.to set up a carbon market
C.to have lower emissions than other countries
D.to increase both emissions and production
【小題2】 China agreeing to limit emissions now because______
A.they care about the environment
B.emissions harm people’s health
C.of pressure from other countries
D.they want more profit for their factories
【小題3】How does the CER scheme work?
A.Countries can buy the right to produce as much carbon emissions as they like.
B.All countries are required to set a carbon emissions cap and can then get certificates on how developed their environmental programme is.
C.Developed countries are allowed to produce more emissions than industrial countries.
D.Developed countries can buy the right to produce more carbon emissions from developing countries that produce less.
【小題4】 What is the main idea of this passage?
A.Air pollution is still increasing the problem of climate change all over the world.
B.China is still resisting cutting emissions as it is necessary for the manufacturing industry.
C.China believes that it is free from meeting international standards on emissions.
D.China will need to cut its emissions in the near future in order to keep up with the international community

Below is a selection from a popular science book.

If blood is red, why are veins (靜脈) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
That kind of question depends on whether you are busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five tunes as much blood to feed it.
Why do teeth fall out, and why don't they grow back in grown-ups?
Baby (or "milk") teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you're done. When they're gone, they’re gone. This is because nature figures you're set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and do. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects, of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don't really shrink! It is not that they are growing backwards ---- their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little. Or, more often, become more bait and curved.
Why does spinning make you dizzy (眩暈的)?
Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you're moving while you're Dot!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s "use it, or lost it”! It's not that exercise makes you healthy; it's more that a lack of exercise leaves your body weak and easily affected by disease.
 
【小題1】What is the colour of blood in a vein near the surface of the skin?
A.Blue.  B.Dark reddish purple. 
C.Red.  D.Light yellow. 
【小題2】Why do some old people look a little shrunken as they age?
A.Because they are more easily affected by gravity. 
B.Because their spine is in active use. 
C.Because their spine becomes more bent. 
D.Because they keep growing backwards. 
【小題3】Which of the following statements about our brain is true?
A.In the long run, our brain probably works harder than our heart. 
B.When our brain senses the spinning, we will fell dizzy. 
C.The brains of the other mammals are as complex as those of humans. 
D.Our feelings and emotions come from the most developed area in our brain. 
【小題4】What is the main purpose of the selection?
A.To give advice on how to stay healthy. 
B.To challenge new findings in medical research. 
C.To report the latest discoveries in medical science. 
D.To provide information about our body.

For the people living in the Nile Basin, the river is their life.This 6,825 km waterway, whose watershed(流域)covers three million square kilometers, flows through mountains ,woodlands, lakes and deserts.Its potential for fishing, tourism and shipping is great—but so are its challenges. 
Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well.Today, about 160 million people depend on the Nile River for their living.Within the next 25 yeas ,the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture.The frequent drought(干旱)adds to the urgency.
Water quality is also a problem.Precious soil is washed out to sea.Wastes from industry and agriculture create pollution.Higher concentrations of salt influence irrigated soils.Water-borne diseases continue unchecked.In areas where it's hot and damp, water hyacinths choke off(阻止) lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day.They’ve seen the river change course, and their only source(來源) of water thickened with mud.They’re very poor and have few choices.
But a new program, the Nile Basin Initiative (NBI), is offering very practical assistance.The program is more than just a water-management project.It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions.Half the Nile Basin's countries are among the world's poorest nations;yet, somehow, they must find the resources, skills and political will to overcome these challenges.
【小題1】What are the great challenges the Nile Basin faces?    

A.The development of shipping industry.
B.Over fishing of native people.
C.Water shortage and water quality.
D.Increasing population and tourism.
【小題2】The underlined word “hyacinths” (in Paragraph 3) refer to “        ”.      
A.plants B.a(chǎn)nimals C.rocks D.salts
【小題3】The program NBI is mainly aimed at           .                 
A.preventing water pollution
B.improving living condition of the poor
C.changing the river course
D.preventing land from becoming desert
【小題4】
A.People’s Life in Egypt and Sudan
B.Frequent Drought in Egypt and Sudan
C.The Poorest Countries in the Nile Basin
D.The Ecosystem Problems in the Nile Basin
