Meat and vegetables are measured in grams and kilograms. Milk and other liquid foods are measured in liters or milliliters. These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body.

Our bodies use varying（不同程度的） amount of calories. The more exercise we take, the more calories we burn. If we eat food which contains more calories than we use up, then it is possible that we would increase in weight. In order to avoid becoming overweight, it is advisable to eat a balanced diet and not eat too many foods that have a high calorie rating. The table below gives you some idea of the number of calories in food.

Dr. Sylvia Earle wants you to stop eating fish. It's not because fish are endangered, though wild fish stocks in many oceans are very low. It's not because they're bad for you, though fish in many areas are exposed to poisonous substances in the water. It’s because they're smart.
"Fish are sensitive, they have personalities," says the marine biologist. For Earle, eating a fish would be like eating a dog or a cat. "I would never eat anyone I know personally."
There's a lot more to fish than meets the eye: they talk to each other, they like to be touched, and they engage in behavior that can seem very human. They can remember things and learn from experience. Earle and a growing number of animal rights activists see these as strong arguments against eating fish altogether.
The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket. "While it may seem conspicuous that fish are able to feel pain, like every other animal, some people think of fish as swimming vegetables," says Dr. Lynne Sneddon. "Really, it's kind of a moral question. Is the enjoyment you get from fishing (or eating fish) more important than the pain of the fish?"
Fishermen and (fried) fish lovers are skeptical. "I've never seen a smart fish," says Marie Swaringen as she finishes off a plate of fish at a Seattle seafood restaurant. "If they were very smart, they wouldn't get caught."
"For years, everyone's been telling us to eat fish because it's so good for us," says another diner. "Now I've got to feel guilty while I'm eating my fish? What are they going to think of next? Don't eat salad because cucumbers have feelings?"
【小题1】According to Dr. Sylvia Earle, he would stop eating fish as a result of the following reasons EXCEPT ___________ .

A．Fish are sensitive and have personalities
B．He knows fish very well
C．Fish are dangerous to eat because the water is polluted
D．Fish are clever
【小题2】Dr. Lynne Sneddon describes the behavior of eating fish in a(n) _______ tone.
A．opposedB．optimisticC．indifferentD．supportive
【小题3】Which word below can take the place of the underlined word “conspicuous” in Paragraph 4?
A．obviousB．easyC．impossibleD．necessary
【小题4】It can be inferred from the last paragraph that _____________ .
A．Human beings should stop eating fish
B．We would feel guilty if we continued eating fish
C．People eat fish because fish are delicious
D．Cucumber is a kind of vegetable or fruit
【小题5】What was the author’s purpose when writing this passage?
A．To advise people to stop eating fish.
B．To introduce a topic of whether people should eat fish.
C．To advise people not to stop eating fish.
D．To tell us that fish will feel pain when caught and transported.

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants produce volatile compounds (挥发性化合物) —— chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from such volatile compounds to attract insects such as bugs and bees.
Plants can also discover  volatile compounds produced by other plants. A tree under attack by hungry insets, for instance, may give off these chemicals in order to let other trees know about the attack. In response, the other trees may send off their chemicals to keep the bugs away —— or even chemicals that will attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying: a chemical sensor (传感器) called an “electronic nose”. The “e-nose” can tell such compounds as plants make. When plants are attacked, scientists say, the e-nose could help quickly decide whether plants are being eaten by insects. But today, the only way to spot such insects is to inspect individual plants by observing them. This is a challenging task for managers of greenhouses, including those that can house thousands of plants. The research team is working with an e-nose that can recognize volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds based on the interactions (相互作用), and then the e-nose will give off electronic signals that the scientists can analyze by using computer software.
To test the e-nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all being common greenhouse crops. Then scientists collected samples of the air around damaged leaves from each type of crop. These plants had been damaged either by insects or by scientists who made holes in the leaves with a hole punch (打孔器).
The e-nose, it turns out, can identify healthy cucumber, pepper and tomato plants based on the volatile compounds they produce. It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage —— by insects or with a hole punch —— had been done to the tomato leaves.
With some fine-tuning (微调), a device like the e-nose can one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this can also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, India, who studies smells of flowers and plants. Hopefully, scientists believe, the device can bring large benefits to greenhouse managers in the near future.
【小题1】We learn from the text that plants communicate with each other by ______.

A．making some sounds
B．waving their leaves
C．producing some chemicals
D．sending out electronic signals
【小题2】What did the scientists do to find out if the e-nose worked?
A．They fixed 13 sensors inside the device.
B．They presented it with all common crops.
C．They collected different damaged leaves.
D．They do tests on damaged and healthy leaves.
【小题3】According to the writer, the most amazing thing about the e-nose is that it can ______.
A．pick out ripe fruits quite expertly
B．spot the insects in a very quick way
C．tell different damages to leaves
D．recognize unhealthy tomato leaves
【小题4】We can infer from the last paragraph that the e-nose ______.
A．is unable to tell the smell of flowers
B．is not yet tested in greenhouses
C．is designed by scientists at Purdue
D．is helpful in killing harmful insects


第三部分：阅读理解（共15小题，每小题2分；共30分）
阅读下面短文，掌握其大意，然后从各题的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。
A
A man walks into a doctor’s office. He has a cucumber (黄瓜) up his nose, a carrot in his left ear and a banana in his right ear. “What's the matter with me?” he asks the doctor. The doctor replies, “You’re not eating properly.”
This is a popular joke among British school children. It shows Britain's famous dry and satirical (讽刺的) way of seeing the funny side of life. People say this unique sense of humor is one of Britain's national characteristics.
The British sense of humor is different from other countries because it is often more negative. When it comes to making the British laugh, there is nothing that works better than a socially inappropriate (不恰当的) joke. It reflects the culture where mocking (嘲弄) is part of everyday life.
While most Britons don’t take these jokes too seriously, foreigners often don’t understand them. A recent survey found that most foreigners who visited Britain think the British are “unfriendly and have almost no sense of humor”.
Are the British just not as funny as they think they are? Leo McKinstry, a British journalist, thinks the British are funny. “Accusing the British of having no sense of humor is like telling Rolls-Royce (劳斯莱斯) that its cars are cheap and not good in quality,” he says.
56. What does the doctor actually mean by the remark “You’re not eating properly”?
A. What you have had is the cause of these problems.   B. You are not having the right food.
C. You don’t eat the way people usually do.           D. You eat with the wrong cutlery. ( 餐具 )
57. The word “dry” in Paragraph 2 means ________.
A. without water or liquid inside                 B. special and popular among school children
C. dull and meaningless                        D. funny and clever while seeming to be serious
58. Why do most visitors, who once visited Britain, think that the British are unfriendly?
A. Because the British always take things seriously.
B. Because the British have no sense of humor.
C. Because the British are cold and difficult to get along with.
D. Because the British have a different sense of humor.
59. Which of the following is NOT the characteristics of British humor?
A. dry and satirical                             B. negative and mocking
C. encouraging and gentle                        D. clever and witty
