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.

A funny thing happened on the way to the communication revolution: we stopped talking to one another.
I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and suddenly, I became invisible, absent from the conversation.
The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communication technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice-mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine.
As almost every contact we can imagine between human beings gets automated, the emotional distance index goes up. You can’t even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated.
I am not against modern technology. I own a cell phone, an ATM card, a voice-mail system, and an email account. Giving them up isn’t wise. They’re a great help to us. It's some of their possible consequences that make me feel uneasy.
More and more, I find myself hiding behind email to do a job meant for conversations or being relieved with voice-mail picking up because I don't really have time to talk. The industry devoted to helping me keep in touch is making me lonelier.
【小題1】Which of the following would be the best title of the passage?
| A．The Advance of Modern Technology |
| B．The Consequences of Communication Technology |
| C．The Story of Communication Revolution |
| D．The Automation of Modern Communication |
| A．The author has decided not to use his phone when he is with his friend. |
| B．Modern technology makes it hard for people to have a face-to-face talk. |
| C．The limited use of communication device brings much inconvenience to the author. |
| D．The industry intended to keep people in touch is taking them away from each other. |
| A．satisfying | B．encouraging |
| C．disappointing | D．embarrassing |
| A．modern technology is bridging the people |
| B．modern technology is separating the people |
| C．modern technology is developing too fast |
| D．modern technology is interrupting people |

Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．
We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天線)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．
【小題1】Which of the following is NOT done by satellites according to the passage?
| A．Sending information for weather forecast |
| B．Taking photographs of the Earth |
| C．Sending TV pictures |
| D．Providing food for airplane pilots |
| A．35,880 kilometers per hour． | B．335,880 kilometers per hour |

Societies all over the world name places in similar ways. Quite often there is no official naming ceremony but places tend to be called names as points of reference by people. Then an organized body steps in and gives the place a name. Often it happens that a place has two names: One is named by the people and the other by the government. As in many areas, old habits died hard, and the place continues to be called by its unofficial name long after the meaning is lost.
Many roads and places in Singapore are named in order that the pioneers will be remembered by future generations. Thus we have names such as Stamford Road and Raffles Place. This is in keeping with traditions in many countries ---- in both the West and the East.
Another way of naming places is naming them after other places. Perhaps they were named to promote friendships between the two places or it could be that the people who used to live there were originally from the places that the roads were named after. The mystery is clearer when we see some of the roads named in former British bases. If you step into Selector Airbase you will see Piccadilly Circus ---- obviously named by some homesick Royal Air Force personnel.
Some places were named after the activities that used to go on at those places. Bras Basah Road is an interesting example, “Base Basah” means “wet rice” in Malay. Now why would anyone want to name a road “Wet Rice Road”? The reason is simple. During the pioneering days, wet rice was laid out to dry along this road.
A few roads in Singapore are named by their shapes. There is “Circular Road” for one. Other roads may have parts of their names to describe their shapes, like “ Paya Lebar Crescent”. This road is called a crescent (月牙) because it begins on the main road, makes a crescent and comes back to join the main road again.
【小題1】We learn from Paragraph 1 that _____.
| A．the government is usually the first to name a place |
| B．a(chǎn) ceremony will be held when a place is named |
| C．people prefer the place names given by the government |
| D．many places tend to have more than one name |
| A．Selector Airbase. | B．Raffles Place. |
| C．Piccadilly Circus. | D．Paya Lebar Crescent. |
| A．Change suddenly. | B．Change greatly. |
| C．Disappear very slowly. | D．Disappear quickly. |
| A．a(chǎn)fter a place | B．a(chǎn)fter an activity |
| C．a(chǎn)fter a person | D．by its shape |
| A．The way Singaporeans name their places is unique. |
| B．Some places in Singapore are named for military（軍事） purposes. |
| C．Young Singaporeans have forgotten the pioneers. |
| D．Some place names in Singapore are the same as in Britain. |

In a recent study, researchers have estimated the energy required to produce bottled water, including the energy required to manufacture plastic, make the plastic into bottles, process the water, fill and seal the bottles, transport the bottles, and chill the bottles for use. Combining all the energy input totals for treatment and distribution, researchers found that producing bottled water requires between 5.6 and 10.2 million joules(焦耳) of energy per liter, depending on transportation factors. That's up to 2, 000 times the energy required to produce tap water.
To break down the energy requirements, researchers found that producing the plastic bottles and transporting the bottles greatly dominated(控制) the energy input. Although some companies are experimenting with producing lightweight bottles or using recycled materials, the researchers calculated that the manufacturing cost is about 4 million joules of energy per plastic bottle weighing 38 grams, and the cap weighing 2 grams.
“Our previous work had suggested that bottled water production was an energy intensive process, but we were surprised to see the results, ” the researchers said.
Transportation costs vary depending on the distance and mode of transport and both factors depend on the type of bottled water. There are two main kinds of bottled water in the US:” spring water” which comes from an underground spring and “purified water”,which is city tap water that has received further treatment. For purified water distributed locally by truck within Los Angeles, the total transportation energy is about 1.4 million joules per liter. In the second situation, spring water shipped from Fiji (such as Fiji Spring Water) across the Pacific to Los Angeles, and then delivered locally by truck requires about 4 million joules per liter for transportation. For the spring water, the transportation energy equaled (in the case of Fiji) the energy required to produce the bottle.
With this data, the researchers hope that future studies will have the ability to make specific estimates for different situations, and possibly find ways to cut energy costs.
【小題1】From the first Paragraph we can know that the energy required to ______.
| A．produce bottled water includes the energy required to drink it |
| B．distribute bottled water includes the energy for producing the bottles |
| C．distribute bottled water is much smaller than the energy for treating it |
| D．produce bottled water is much smaller than the energy for producing tap water |
| A．to fill tap water into the plastic bottles directly |
| B．to replace the plastic bottles with metal containers |
| C．to produce lightweight bottles with recycled materials |
| D．to use bicycles to transport and deliver bottled water locally |
| A．Treatment of bottled water needs no energy input at all. |
| B．Bottled water production is an energy intensive process. |
| C．Transportation of bottled water takes up the most energy input. |
| D．Production of the plastic bottles greatly dominated the energy input. |
| A．there are two main kinds of bottled water in the US |
| B．world consumption of bottled water has been increasing |
| C．transportation costs have something to do with the mode of transport |
| D．bottled water produced in Spring is more expensive than purified water |
| A．To help consumers themselves make more environmentally sustainable choices. |
| B．To advise the government to take severe measures to stop producing bottled water. |
| C．To urge the consumers to drink tap water instead of bottled water for the sake of the earth. |
| D．To try the best to find ways to produce bottled water cheaply and quickly for the companies. |

Empathy(同情心) lets us feel another person’s pain and drives us to help. Do any other animals feel empathy? Scientists recently found that rats(老鼠) do, too.
Most people don’t like rats. In many people’s eyes, rats are only bad. But Jean Decety and his partners at the University of Chicago did an experiment. It showed that rats are kind, warm-hearted animals. They can feel each other’s pain.
Scientists placed pairs of rats in plastic cages(籠子) for two weeks. During this time they got to know each other. Then they put one of the rats from each pair into a small container(容器) in the cages. The small container had a door. It was so designed as to fall to the side when the free rat touched it. Many of the trapped(困住的) rats squeaked(吱吱叫) to show their discomfort. The other rats of the pairs could see their suffering(受苦的) friends clearly.
In most pairs, the free rats would become very worried about their friends. They kept trying to save their friends again and again throughout the month. Scientists put the rats’ favorite chocolate in the cages, but the rats didn’t eat it until they had saved their friends successfully. Scientists also found that female rats seemed to act more empathetic than male rats.
“The results are the first to show that rats take action in response to another’s trouble,” Decety said. “Monkeys and chimpanzees have similar behavior. But unlike those animals, rats can be ready used in laboratory studies. They will help us to learn which parts of the brain lead to empathy and helping behavior and whether empathy is natural.”
【小題1】A person with empathy is often _____.
| A．kind-hearted | B．clever | C．a(chǎn)ctive | D．strong |
| A．Because they were not hungry at that time. |
| B．Because chocolate was not their favorite food. |
| C．Because they wanted to save the trapped rats first. |
| D．Because they were afraid that the chocolate was bad. |
| A．Monkeys. | B．Chimpanzees. | C．Rats. | D．Cats. |
| A．Rats can feel other animals’ pain. |
| B．Chocolate is rats’ favorite food. |
| C．Rats are empathetic and can feel each other’s pain. |
| D．Female rats are more empathetic than male rats. |

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. |
| A．Medical treatment. | B．People’s good kidney. |
| C．Level of people’s activity. | D．Positive life attitude. |
| A．their bodies produce T-cells |
| B．their bodies are unable to fight diseases |
| C．they have reduced strength, loss of hair |
| D．they become weaker and weaker |
| A．producing more low calorie food allows people to keep young |
| B．the more Chinese herbal medicine people drink, the better for health |
| C．people should try to quicken the production of T-cells in the body |
| D．it remains unknown how effective Dr. Shen’s herbal medicine is |

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.
In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.
The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.
【小題1】Not enough sleep can cause obesity by ______.
| A．burning more of your energy |
| B．making you want to eat more food |
| C．keeping you from doing exercise |
| D．helping you feel great without food |
| A．have your ghrelin level rise and leptin level drop |
| B．have your leptin level rise and ghrelin level drop |
| C．have your ghretin and leptin levels properly balanced |
| D．have your hunger increase and your weight decrease |

It's not about how much money you make, and it's not about who your daddy is. We're talking about being attractive in general, whether it's on a job interview or just gaining the respect of your colleagues . . .
Ask lots of questions
If you come across as a know-it-all (even if you really do know it all!), it really pushes people away. Rather, asking lots and lots of questions makes people feel like you care, you can be trusted.
Great body language
Your body language says a lot about you - it says whether you have confidence, or simply if you really care. Talking physically, it is one of the most important physical characteristics you need!
Stay busy
Always have something to do. Have you ever seen someone just sitting around, doing nothing? How unattractive. Always be busy with something, even if for some reason you have to make something up.
Show your pearly whites (or just smile)
Smile more, no matter how ugly your teeth are. I'm not kidding about this one. It's not all about the teeth. If you are smiling genuinely, you can draw everyone for 100 meters around to you.
Wear what fits
Wear clothing that fits you. For women, wearing tight pants or shirts is not attractive. Things that just fit you and your shape are the best but not tight. Wear things that fit you nicely, please . . . And for goodness sake, both sexes, stay away from logos and printed shirts! Most people you may ask do not find this attractive. Stop being some company's billboard(廣告牌).
Be interested in other man
Be interested in the other person. Don't talk about. If you are truly interested in the person, it will come across. And if you want to talk about yourself, you'll find that putting the other person first actually opens him up to return the favor and ask you questions. See how fun this is?
【小題1】It is your ________ that makes you attractive.
| A．your family background |
| B．fashionable tight clothes |
| C．your appearance and your wealth |
| D．proper body language and behavior |
| A．a(chǎn)lways smile and show your pearly teeth |
| B．keep asking lots of questions |
| C．a(chǎn)re interested in other people’s personal affairs |
| D．a(chǎn)lways wear clothes that fit you |
| A．gain praises from your boss and colleagues |
| B．look attractive among people |
| C．show that you are interested in your job |
| D．get promoted in your company |
| A．Wearing a shirt with printed logos |
| B．Keeping talking about your own experiences and talents |
