A

The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep color in meats and other food additives（添加劑）caused cancer.

Yet, these additives remain in our food, and it is difficult to know which things on the wrappings of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin (青霉素) to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.

The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.

51. According to this passage, we can know___________.

A. cancer was discovered in 1945

B. science has made food unfit to eat

C. perhaps most of human illness is caused by what we eat

D. perhaps most kinds of cancer are related to what people eat

52. The additives in food_________.

A. are bright and colorless                   B. have indirect effects on our health

C. have direct effects on our health          D. have direct and indirect effects on our health

53. People use additives_________.

A. to change color of the food               B. to make food more unfit to eat

C. to take off the diseases of the food        D. to improve the color and taste of the food

54. Which of the following is Not true?

A. We needn’t take care of what we eat.

B. Some wrappings of food are harmful.

C. “The practice continues” means “things are still going on like that”.

D. Farmers try to make more money on the market by fattening their animals.

III、閱讀理解（共20小題；每小題2分，滿分40分）
閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C、D）中，選出最佳選項(xiàng)。
A
Do dogs understand us?
Be careful what you say around your dog. It might understand more than you think.
A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.
The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked
out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.          
Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品種)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!
41. From paragraph 3 we know that _________.
A. animals are as clever as human beings
B. dogs are smarter than parrots and chimpanzees
C. chimpanzees have very good word-learning skills
D. dogs have the same learning abilities as 3-year-old children
42. Both experiments show that          .
A. Rico is smart enough to get all commands right
B. Rico can recognize different things including toys
C. Rico has developed the ability of learning mathematics
D. Rico won't forget the names of objects once recognizing them
43. Which of the following statements is true?
A. The purpose of the experiments is to show the border collie's mental abilities.
B. Rico has a better memory partly because of its proper early training.
C. The Border collie is world-famous for recognizing objects.
D. Rico is born to understand its owner's commands.
44. What does the writer want to tell us?
A. To train your dog.                        B. To talk to your dog.
C. To be friendly to your dog.                 D. To be careful with your dog.

III。閱讀理解（共15小題；每小題2分，滿分30分）

閱讀下列短文，從每篇短文后所給各題的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)，并在答題卡上將該項(xiàng)涂黑。

They say there are three ways to experience the Grand Canyon; on foot, on mules（騾子）or by air. We chose the first. Up early, my husband and I and our three children couldn’t wait to get started. We decided to walk along a lovely path named Bright Angel Trail.

As we set out, I was shocked at how narrow the path was. And I couldn’t help noticing that the other tourists weren’t like us. They had heavy backpacks, water bottles, and hats. But as usual we were dressed, As the sun rose higher, Arizona’s famous heat seemed to roast us. There was no shade and our legs were aching. We decided to go back, with the girl on my back and the boys far behind. By the time we finally got back, our legs were like jelly.

The next day, after we’d had a long rest and a good breakfast, we were ready for another view of the Canyon – by air. After our last walk, this would be the easiest thing in the world.

We called to each other excitedly as the plane took off and circled around the Canyon. But the smiles on our faces disappeared as the pilot tossed（翻轉(zhuǎn)）the plane around, pretending he was going to hit the ground. I shouted, “STOP, TAKE US BACK!” When we finally arrived back on land, once again our legs were like jelly. We hardly spoke as we drove back.

As I said, there are three ways to view the Grand Canyon. We never tried the mules, but personally I’d suggest a fourth: buy yourself a good magazine like National Geographic. That way, you can see the Canyon, without fear or tiredness.

1. Which of the following is true according to the second paragraph?

A. They made a careful preparation before the trip.

B. The children were more joyful than their parents.

C. Bright Angel Trail was not as lovely as they expected.

D. The summer heat prevented them from enjoying the view.

2. The underlined expression “Our legs were like jelly” probably means _____ .

A. we were weak                                 B. we were unhappy

C. we were dissatisfied                      D. we were disappointed

3. Which of the following best describes their Canyon trip by air?

A. It proved to be frightening.                 B. It was more comfortable.

C. It turned out to be exciting.                 D. It made each of them tired.

4. We can infer from the passage that _____.

A. experiencing the Canyon on mules would be the best way.

B. one needs to dress less when visiting the Grand Canyon.

C. the writer was not serious when she made the suggestion.

D. the whole family narrowly escaped from the air accident.
