　　Once upon a time there was a great Greek hero, Hercules. He was taller and stronger than anyone you have ever seen. On his shoulder he carried a club and in his hand be held a bow(弓). He was known as the hero of a hundred adventures.
　　Hercules served a king. The king was afraid of him. So again and again he sent him on difficult tasks. One morning the king sent for him and told him to fetch three golden apples for him from the garden of the Singing Maidens(歌女). But no one knew where the garden was.
　　So Hercules went away. He walked the whole day and the next day and the next. He walked for months before he saw mountains far in the distance one fine morning. One of the mountains was in the shape of a man, with long, long legs and arms and huge shoulders and a huge head. He was holding up the sky. Hercules knew it was Atlas, the Mountain God. So he asked him for help.
　　Atlas answered, “My head and arms and shoulders all ache. Could you hold up the sky while I fetch the golden apples for you?”
　　Hercules climbed the mountain and shouldered the sky. Soon the sky grew very heavy. When finally Atlas came back with three golden apples, he said, “Well, you are going to carry the mountain for ever. I’m going to see the king with the apples. ” Hercules knew that he couldn’t fight him because of the sky on his back. So he shouted：
　　“Just one minute’s help. My shoulders are hurting. Hold the sky for a minute while I make a cushion(垫子) for my shoulders. ”
　　Atlas believed him. He threw down the apples and held up the sky.
　　Hercules picked up the apples and ran back to see the king.

2、 Calling for Safe Celebrations This Fourth of July
　　Last Fourth of July, Pete, a 14-year-old boy, was enjoying the lit-up skies and loud booms from the fireworks being set off in his neighborhood. Suddenly, the evening took a terrible turn. A bottle rocket shot into his eye, immediately causing him terrible pain. His family rushed him to the emergency room for treatment. As a result of the injury, Pete developed glaucoma and cataracts. Today, Pete has permanent vision loss in his injured eye because of his bottle rocket injury.
　　June is Fireworks Eye Safety Awareness Month, and through its EyeSmart campaign the American Academy of Ophthalmology wants to remind consumers to leave fireworks to professionals. "There is nothing worse than a Fourth of July celebration ruined by someone being hit in the eye with a bottle rocket," said Dr. John C. Hagan, clinical correspondent for the Academy and an ophthalmologist at Discover Vision Centers in Kansas City. "A safe celebration means letting trained professionals handle fireworks while you enjoy the show."
　　According to the U. S. Consumer Product Safety Commission, more than 9,000 fireworks-related injuries happen each year. Of these, nearly half are head-related injuries, with nearly 30 percent of these injuries to the eye. One-fourth of fireworks eye injuries result in permanent vision loss or blindness. Children are the most common victims of firework abuse, with those fifteen years old or younger accounting for4 50 percent of fireworks eye injuries in the United States. Dr. Hagan estimates that his practice sees more than 30 injuries each year from fireworks.
　　Even fireworks that many people consider safe represent a threat to the eyes. For children under the age of five, apparently harmless sparklers account for one-third of all fireworks injuries. Sparklers can bum at nearly 2,000 degrees Fahrenheit.

1What happened to Pete last Fourth of July?

A.He was burned in a house fire.

B.He was caught in a rain.

C.He was injured in a fight.

D.He was hit in the eye.

2The American Academy of Ophthalmology calls on consumers t

A. celebrate the Fourth of July with fireworks.

B. leave fireworks to professionals in their celebrations.

C.stop celebrating the Fourth of July altogether.

D.set off fireworks together with trained professionals.

3How many fireworks eye injuries occur in the US each year?

A.About 9,000.

B.About 4,500.

C.About 1,350.

D.About 30.

4 Fireworks eye injuries can result in each of the following EXCEPT

A.blindness.

B.permanent vision loss.

C.glaucoma and cataracts.

D.head-related injuries.

5Which is NOT true of sparklers?

A.They are harmless to children.

B.They are considered safe by many people.

C.They are a threat to the eyes.

D.They can burn at very high degrees

3、 Bringing Nanotechnology to Health Care for the Poor
　　Nanotechnology uses matter at the level of molecules and atoms. Researchers are finding different uses for particles with a length of one nanometer, or one-billionth of a meter. These include things like beauty products1 and dirt-resistant clothing. But one area where many experts believe nanotechnology holds great promise is medicine.
　　Last week, speakers at a program in Washington discussed using .nanotechnology to improve health care in developing countries. The program took place at the Woodrow Wilson International Center for Scholars. Peter Singer at the University of Toronto says a nanotechnology called quantum dots2 could be used to confirm eases of malaria. He says it could offer a better way than the traditional process of looking at a person''s blood under a microscope.
　　In poor countries, this process is often not followed. As a result, sick people may get treated for malaria even if they do not have it. Such misuse of medicines can lead to drug resistance. Quantum dots are particles that give off3 light when activated. Researchers are studying ways to program them to identify diseases by lighting up in the presence of a targeted molecule. 4
　　Experts say nanotechnology shows promise not just for diagnosing diseases, but also for treating them. Piotr Grodzinski of the National Institutes of Health5 talked about how nanotechnology could make drugs more effective. He talked about cancer drugs already developed with nanotechnology. He says if a drug can target a cancer locally in the body, then much less of it might be needed, and that means lower side effects. 6
　　Andrew Maynard is chief scientist for the Project on Emerging Nanotechnologies at the Woodrow Wilson Center. He noted that Brazil, India, China and South Africa are currently doing nanotechnology research that could help poor countries. But he also noted that there is some risk in using nano-materials. He says nanometer-sized particles behave differently in the body and the environment compared to larger particles7. Experts say more investment in research is needed to better understand these risks.

1Which of the following uses of nanotechnology is NOT mentioned in the passage?

A.To make beauty products and dirt-resistant clothing.

B.To produce better and lighter building materials.

C.To help more accurately diagnose diseases.

D.To help more effectively treat diseases.

2How can quantum dots be used to confirm diseases?

A.By traditionally looking at a person''s blood under a microscope.

B.By letting a person take some kind of medicine.

C.By lighting up in the presence of a targeted molecule.

D.By subjecting a person to an X-ray examination.

3How can nanotechnol0gy be used to make a drug more effective?

A.By making a drug target the focus of a disease.

B.By changing the structure of the body ceils.

C.By lowering the side effects caused by a drug.

D.By letting a patient take a dose as large as possible.

4 The following developing countries are doing very well scientific research on nanotechnology EXCEPT

A.China

B.Brazil

C.Iran

D.India

5Which of the following is the possible risk in using nano materials mentioned in the passage?

A.They may cause some damage to the body cells.

B.They are harmful materials themselves.

C.They may store in the body.

D.They may behave differently in the body and the environment
