We can stay young forever. That is the message Dr. Shen Ziyin wants to give the world. And the Chinese doctor claims that he has found an answer to the problems of aging.
His solution is a herbal medicine to slow the process of aging.
Dr. Shen Ziyin has been trained in Western medicine. At the same time he studied traditional Chinese medicine. And, he has been working for the past forty years to put together the best of both and find a cure for aging. He has
taken a hint from its aging process. It is responsible for the level of activity that the human bodies go through Studies conducted by Dr.Shen show that herbal medicine based on the shen system slow the the ancient Chinese medicine system called “shen”.
According to Shen, it is the kidney（腎臟）which adjusts the functioning of the body as well as aging process, says a report in The Telegraph newspaper.
We notice that when people grow old, they have reduced strength, loss of hair, backache, weakness in general, and wrinkles, among others. This happens because when people grow old, their bodies produce T-cells. These T-cells contain a particular substance called Fas. Fas makes the cells in the body destruct themselves.
So the only way to slow down aging is to slow the production of T-cells in the body. This can happen if people eat low calorie food. Then the body is not active enough to produce extra T-cells. But, is going hungry all the time a good price to pay for staying young?
This is where Dr. Shen’s herbal medicine comes in. But how effective it will be, only time can tell.
【小題1】How did Dr. Shen find the solution to the problem of aging?
| A．By studying Western medicine. |
| B．By learning traditional Chinese medicine. |
| C．By combining both Western and Chinese medicine. |
| D．By doing research on both Western and Chinese people. |

【小題3】A
【小題4】D
解析試題分析：本文介紹了Dr. Shen在幾十年中，通過中西醫(yī)結(jié)合的方法，研究并發(fā)現(xiàn)了人變老的原因，推出了自己獨特的中藥來延緩衰老。根據(jù)Dr Shen的理論，人變老是由于人體的腎臟器官會隨著年齡的增長而產(chǎn)生一種T-cells，如果想延緩衰老就要減少T-cells的產(chǎn)生。但是這種理論還有待于證實。
【小題1】C細(xì)節(jié)理解題。從文章第三段And, he has been working for the past forty years to put together the best of both and find a cure for aging.可知他是通過中西醫(yī)結(jié)合研究出了人變老的奧秘。所以C選項正確。
【小題2】B細(xì)節(jié)理解題。文中提到 it is the kidney（腎臟）which adjusts the functioning of the body as well as aging process,腎臟調(diào)節(jié)人體的功能以及變老的過程，由此可知B為正確選項。
【小題3】A細(xì)節(jié)理解題。從文章倒數(shù)第三段可知This happens because when people grow old, their bodies produce T-cells.因為人變老的時候，他們的身體產(chǎn)生T-cells。所以A選項正確。
【小題4】D推理判斷題。從文章末句But how effective it will be, only time can tell.可以判斷作者不能確定效果，藥物如何還需要時間的檢驗，所以D選項正確。句意：但是效果會如何呢，只能靠時間來證明。

Let us begin by saying what does not cause our dreams. Our dreams do not come from “another world ”. They are not messages from outside source. They are not a look into the future , either ．
All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry , or tired or cold , his dreams may include a feeling of this kind ．If the covers on your body , such as a quilt or a blanket have slipped off your bed , you may dream that you are sleeping on the ice and snow. The material for the dream you will have tonight is likely to come from the experience you have today.
So the subject of your dream usually comes from something that has effect on you while you are sleeping （feeling of cold, a noise, a discomfort, etc．） and it may also use your past experiences and the wishes and the interests you have now．This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, home-sick soldiers of their families and prisoners of freedom．
To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream , here is the story of the experiment．A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton．He would dream he was in hospital and his charming girlfriend was visiting him , sitting on the bed and feeling gently his hands!
There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean．Their explanations of dreams , though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem．They believe that dreams are mostly expressions of wishes that do not come true．In other words, dreams are a way of having your wishes carried out．
【小題1】From the passage we know that our dreams ___________.
| A．a(chǎn)re imagination of our daily life |
| B．a(chǎn)re man’s curious look into the future |
| C．have nothing to do with our feelings |
| D．a(chǎn)re to some degree connected with our feelings |

| A．is considered interesting , but unreasonable |
| B．gives a good answer to the question why we dream |
| C．has some value , though not fully convincing |
| D．has been proved by the findings of their studies |
| A．Why People Dream ? | B．New Findings about Dreams |

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut he greenhouse gases they send out, which are thought to be responsible for global warming.
Thanks to special bacteria in their stomachs, kangaroo flatulence(腸胃氣脹)contains no methane(甲烷)and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.
While the usual image of greenhouse gas pollution is a billowing smokestack (煙囪) pushing out carbon dioxide, farm animals’ passing wind contribute a surprisingly high percentage of total emissions (排放物)in some countries.
“Fourteen percent of emissions from all sources in Australia are from enteric methane from cattle and sheep,” said Athol Kleve, a senior research scientist with the Queensland state government.
“And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent, ” he said.
Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.
But it will take researchers at least three years to isolate (分離) the bacteria, before they can even start to develop a way of transferring it to cattle and sheep.
Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.
The idea is controversial (有爭議的), but about 20 percent of health-conscious Australians are believed to eat the national symbol already.
“It's low in fat, it’s got high protein levels and it's very clean in the sense that basically it's the free-range (放養(yǎng)的) animal,” said Peter Amp of the University of New South Wales's institute of environmental studies.
【小題1】Scientists intend to put bacteria into cattle and sheep _________.
| A．so that they can make full use of special bacteria |
| B．to help Australian farmers to earn more money |
| C．so that they can protect Australian ecosystem |
| D．to prevent them from sending out harmful gases |
| A．cattle and sheep produce more carbon dioxide |
| B．less cattle and sheep are raised in New Zealand |
| C．farm animals are responsible for greenhouse gases |
| D．New Zealand has the most animals in the world |
| A．Australians should farm fewer cattle and sheep and just eat more kangaroos. |
| B．The bacteria could make the digestive process much more efficient. |
| C．Australians should give kangaroo - style stomachs to cattle and sheep. |
| D．The bacteria could save millions of dollars in feed costs for farmers. |
| A．it is rich in protein | B．it is cheaper than beef |
| C．it is high in fat | D．it is more delicious than sheep |

Lettuce (萵苣)has been eaten for over 4,500 years, and was known to the Egyptians, Greeks and Romans. Now, people in some countries start the meal with lettuce as part of a salad. There are hundreds of kinds of lettuce. The main ones include head lettuce, such as iceberg, leaf lettuce ,Boston, bibb and romaine.
Experts say lettuce is one of the easiest crops to grow in your garden. The best time to plant the seeds is during cool weather. The University of Illinois Extension advises that the best planting temperature is 15 0C.
Lettuce seeds are small, so do not place them too deep in the ground. If you plant some seeds every week or two, you will have crops ready to eat one after another.
To start the seeds inside, you can use a seed tray in your home or other shelter. This container should be deep enough to hold at least three centimeters of soil or more. There should be about one centimeter of space between the soil and the top of the container. The container should have holes in the bottom so the extra water can flow out. Drop the seeds over the surface and cover them lightly with soil. If the soil is not already a little wet, give it some water. But do not drown the seeds.
Next, cover the seed tray with paper. When the seedlings have come up far enough to touch the paper, take it off. You can transplant the seedlings into the garden when they are about two to three centimeters tall. Do this when the weather is not too hot and not too cold. Take out as much soil as you can with the seedlings, Then dig a hole in the ground bigger thanthe lettuce roots. Water the plants but not too heavily.
Harvest leaf lettuces when the leaves are big enough to eat. Pull the leaves from the outside of the planting so the inside leaves will keep growing. Or, you can cut off the whole plant. Leave about two or three centimeters above the ground so the plant will re-grow. Cut off head lettuces at ground level.
Lettuce is best when served fresh, so make a salad and enjoy. Experts say lettuce is one of the easiest crops to grow in your garden.
【小題1】Which of the following shows the right order of planting lettuces?
a.Dig a hole in the ground bigger than the lettuce roots.
b.Drop the seeds over the surface.
c.Water the plants.
d.Cover the seed with soil.
e.Take off the paper.
f.Transplant the seedlings into the garden.
| A．b, d, e ，f, a, c | B．a(chǎn), b ，c, d ，e, f |
| C．d, e，f, b，a，c | D．b，c, d，e，f，a |
| A．containers | B．seeds | C．young plants | D．layers |
| A．store it in plastic bags | B．eat the inside leaves |
| C．wrap it in paper | D．eat while it is fresh |
| A．Lettuce is the easiest crop to grow in your garden. |
| B．The lettuce is not hard to plant and store. |
| C．We can plant lettuce in a two-centimeter-high tray. |
| D．We should water lettuce at least twice a day. |

American researchers found females are the more talkative sex because of a special “l(fā)anguage protein(蛋白質(zhì))” in the brain.
The study, conducted by neuroscientists （神經(jīng)學(xué)家）and psychologists from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day—over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal（能發(fā)出聲音或語言的） than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic（超聲波的） range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups幼崽were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.
“Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals.”
【小題1】From the second paragraph, we can learn that ________.
| A．women always speak more words than men |
| B．men and male rats have low levels of language protein |
| C．women and male rats have similar levels of Foxp2 |
| D．McCarthy isn’t the first to find females more talkative |
| A．paid attention to | B．related to | C．put pressure on | D．counted on |
| A．test which part of the brain is key to language in rats and humans |
| B．prove the levels of Foxp2 protein in humans and rats are different |
| C．determine the reason why female rats are more talkative than male rats |
| D．discover the association between Foxp2protein and vocal communication |
| A．Tests on humans and rats | B．Why women are the talkative sex |
| C．Sex differences in fussed over | D．Foxp2 protein determines oral ability |

If you hear the sound of running water the next time you call a co-worker on his or her mobile phone, don’t be surprised. Three-fourths of Americans with mobile phones say they use them in the bathroom, a new study shows.
Approximately(大約) the same number of men and women have used the phone in the bathroom, according to a survey of 1,000 Americans by 11 mark, an integrated marketing agency, although men seem more attached to IT in the toilet: 30 percent of men versus(VS) 20 percent of women agreed with the statement, "I don't go to the bathroom without my mobile phone."
More than half the surveyed users (63 percent) said they have answered a phone call in the bathroom, and almost half (41 percent) reported initiating a phone call. That's not all, however. What goes on behind the walls of the stalls(小隔間) is anything a mobile phone is capable of. Sixty-seven percent said they have read a text, and 39 percent have surfed the Web. Men work more from the bathroom — 20 percent said they have participated in work-related calls, versus 13 percent of their female colleagues.
As expected, Gen Y(1981年后出生的一代) respondents(調(diào)查對象) are the pacesetters(先導(dǎo)者) in the "mobile everywhere" movement, with 91 percent using their phone in the bathroom. Still, older generations are not far behind. Eighty percent of Gen X(1961-1981) reported using the phone in the bathroom, as did 65 percent of Baby Boomers(1946-1965) and 47 percent of the Silent Generation(1925-1945).
While online, they are doing more than just surfing; 16 percent of Gen Y report they have made an online purchase while in the bathroom. Users of iPhones are particularly likely to browse and buy in the bathroom – 22 percent have made a purchase, versus 10 percent of Americans with mobile phones overall.
"The writing is on the stall," said 11 mark principal Nicole Burdette. "This study confirms what we all know: that the last private place is no longer private."
In the process, high-tech hygiene(衛(wèi)生) is taking a hit, the survey found. While 92 percent of mobile phone users said they wash their hands after using the bathroom, only 14 percent said they wash their phones.
【小題1】Which is the best word to replace the underlined word "initiating"?
| A．receiving | B．experiencing | C．ending | D．beginning |
| A．no wonder mobile phones are used in the bathroom |
| B．the bathroom is a private place for people |
| C．it makes people have no privacy at all |
| D．more men have used the phone in the bathroom |
| A．Using phones in the bathroom has a bad effect on hygiene |
| B．Mobile phones should not be allowed to use in the bathroom |
| C．Most people care about the hygiene after using the bathroom |
| D．Few people wash their phones after using the bathroom |
| A．supportive | B．disapproval | C．subjective | D．objective |

Here is an astonishing and significant fact: Mental work alone can’t make us tire. It sounds absurd. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲勞). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional(情緒的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.
【小題1】 What surprised the scientists a few years ago?
| A．Fatigue toxins could hardly be found in a laborer’s blood. |
| B．Albert Einstein didn’t feel worn after a day’s work. |
| C．The brain could work for many hours without fatigue. |
| D．A mental worker’s blood was filled with fatigue toxins. |
| A．Challenging mental work. | B．Unpleasant emotions. |
| C．Endless tasks. | D．Physical labor. |
| A．He agrees with them. | B．He doubts them. |
| C．He argues against them. | D．He hesitates to accept them. |
| A．have some good food. | B．enjoy their work |
| C．exercise regularly | D．discover fatigue toxins |
