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 colour in meats and other food additives（添加剂）caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin 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.

An underwater robot that can hear the calls of whales, and to help ships to avoid them, has just been successfully tested in the Bahamas.
The scheme relies on a fish-shaped glider that moves freely through the ocean. It can dive down as far as 200 meters below the surface and direct itself by shifting a weight from fore to aft. A microphone attached to the bottom of the glider can pick up calls from all whales, including the high frequency call of the beaked whale, which until now has been difficult to detect. The glider returns periodically to the surface to radio its data back to base, or if that's too far away, it can call a satellite phone and send its information anywhere in the world.
"We are entering a new era of underwater sensing' says Jim Theriault of Defence Research and Development Canada, in Dartmouth, Nova Scotia who ran the trial. "We can put a glider in the Bahamas and monitor it in Nova Scotia. ”
The hope is that naval or other ocean-going operations that use sonar (声呐）will be able to more easily track where whales are, and so avoid using their noisy equipment when they are close by. There is circumstantial evidence that sonar can upset whales and a number of strandings (搁浅）have been seen shortly after naval sonar operations. “We're trying to lower the potential risk by knowing the animals are there，” says Theriault. The shape of the underwater robot is like __________
| A．a man |
| B．a fish |

| D．a turtle |
The underwater robot is built to __________.
| A．help whales move to the Bahamas |

Scientists are racing to build the world's first thinking robot. This is not science fiction： some say they will have made it by the year 2020，Carol Packer reports.
Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (人形机器人）which scientists have built at the Massa-chusetts Institute of Technology (MIT). Kismet is different from the traditional robot because it can show human emotions. Its eyes, ears and lips move to show when it feels happy, sad or bored. Kismet is one of the first of a new generation of androids—robots that look like human beings—which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old.
The optimists (乐观主义者） say that by the year2020 we will have created humanoids (人形机器人） with brains similar to those of all adult human beings. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do? In the future, robots like Robonaut , a humanoid invented by NASA, will be doing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for us. In Japan, scientists are designing androids that will entertain us by dancing and playing the piano.
Some people worry about what the future holds：Will robots become monsters(怪物）？ Will people themselves become increasingly like robots? Experts predict that more and more people will be wearing micro-computers，connected to the Internet, in the future. People will have micro-chips in various parts of their body, which will connect them to a wide variety of gadgets (小装置）. Perhaps we should not exaggerate (夸大）the importance of technology, but one wonders whether, in years to come，we will still be falling in love, and whether we will still feel pain. Who knows? Kismet is different from traditional robots because __________.
| A．it thinks for itself |
| B．it is not like science fiction |
| C．it can look after two-year-old children |
| D．it seems to have human feelings |
What makes Cog special?
| A．It looks like a mother. |
| B．It behaves like a child. |
| C．It can imitate the behavior of a mother. |
| D．It has a huge brain. |
In about 10 years' time from now, robots __________
| A．will become space designers |
| B．will look like monsters |
| C．will behave like animals |
| D．will think like humans |
In the future robots will also __________.
| A．explore space |
| B．entertain people |
| C．move much faster |
| D．do all of the housework |
What is the writer's attitude to robots in the future?
| A．Critical. |
| B．Hostile. |
| C．Objective. |
| D．Enthusiastic. |

Everyone gathered around and Paddy read out loud, slowly, his tone growing sadder and sadder. The little headline said: BOXER RECEIVES LIFF SENTENCE.
Frank Cleary, aged 26, professional boxer, was today found guilty of the murder of Albert Gumming, aged 32, laborer, last July. The jury（陪审团）reached its decision after only ten minutes, recommending the most severe punishment to the court. It was, said the Judge, a simple case. Cumming and Cleary had quarreled violently at the Harbour Hotel on July 23rd and police saw Cleary kicking at the head of the unconscious Gumming. When arrested, Cleary was drunk but clear-thinking.
Cleary was sentenced to life imprisonment with hard labour. Asked if he had anything to say, Cleary answered, “Just don’t tell my mother.”
“It happened over three years ago,” Paddy said helplessly. No one answered him or moved, for no one knew what to do. “Just don’t tell my mother,” said Fee numbly（麻木地）. “And no one did! Oh, God! My poor, poor Frank!”
Paddy wiped the tears from his face and said. “Fee, pack your things. We’ll go to see him.”
She half-rose before sinking back, her eyes in her small white face stared as if dead. “I can't go,” she said without a hint of pain, yet making everyone feel that the pain was there. “It would kill him to see me. I know him so well—his pride, his ambition. Let him bear the shame alone, it’s what he wants. We’ve got to help him keep his secret. What good will it do him to see us?”
Paddy was still weeping, not for Frank, but for the life which had gone from Fee’s face, for the dying in her eyes. Frank had always brought bitterness and misfortune, always stood between Fee and himself. He was the cause of her withdrawal from his heart and the hearts of his children. Every time it looked as if there might be happiness for Fee, Frank took it away. But Paddy’s love for her was as deep and impossible to wipe out as hers was for Frank.
So he said, “Well, Fee, we won’t go. But we must make sure he is taken care of. How about if I write to Father Jones and ask him to look out for Frank?”
There was no excitement in the eyes, but a faint pink stole into her cheeks. “Yes, Paddy, do that. Only make sure he knows not to tell Frank we found out. Perhaps it would ease Frank to think for certain that we don’t know.”Paddy cried because he thought ___________.
| A．Frank did kill someone and deserved the punishment |
| B．Frank should have told Fee what had happened |
| C．what had happened to Frank was killing Fee |
| D．Frank had always been a man of bad moral character |
The underlined sentence “She half-rose before sinking back…”in Paragraph 6 shows that___________.
| A．Fee was so heart-broken that she could hardly stand up |
| B．Fee didn’t want to upset Paddy by visiting Frank |
| C．Fee couldn’t leave her family to go to see Frank |
| D．Fee struggled between wanting to see Frank and respecting his wish |
What can be inferred from the passage?
| A．The jury and the judge agreed on the Boxer’s Sentence of Life Imprisonment. |
| B．The police found Gumming unconscious, heavily struck by Frank. |
| C．The family didn’t find out what had happened to Frank until 3 years later. |
| D．Frank didn’t want his family to know the sentence to him, most probably out of his pride. |
What is Frank and Paddy’s probable relationship with Fee?
| A．Frank is Fee’s son and Paddy is Fee’s brother． |
| B．Frank is Fee’s son and Paddy is Fee’s husband. |
| C．Frank is Fee’s brother and Paddy is Fee’s lover． |
| D．Frank is Fee’s lover and Paddy is Fee’s husband. |
