One day something went wrong with a man’s bicycle chain(链条). The man could not repair it, so he looked    1   for help. The only house nearby belonged to a woman who had    2   there a few months earlier. The man knocked at the door, but the woman did not answer. The door had clear glass in it, and the man    3   see that the woman was home. He decided to knock again. Finally the woman came to the door. The man immediately explained his    4  . “I can fix the chain,” the woman said. Later when the bike was    5   to go, the man said, ‘Thanks. I hope I can help you some day.” “I never need help,” the woman said.

The following week the man was riding his bike    6  he noticed the woman walking down the street. A strong wind suddenly lifted her hat and sent it into the branches(树枝) of an old tree. The woman tried to get her hat with a stick, but she failed. She seemed    7   because she clearly was not dressed for tree-climbing. The man hurried over, quickly climbed up to the hat and    8   it into the woman’s waiting hands. When she put on her hat, she    9   the man as he climbed back on his bike. ‘I think I told you I never need help,” the woman said, “I’m glad you didn’t    10   me. Thanks.” Then they both smiled.

Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. “It’s a quite dangerous job,” says Giorgio Pezzuto of D’ Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber.
“The idea is to operate a machine far away that can do the stabilizing job without a human being near,”says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.
【小题1】The underlined word “event” refers to_____

All living things on the earth need other living things to live. Nothing lives alone. Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they form a food chain(食物链).Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links disappears.

All life needs sunlight to live on. But only plants can use sunlight directly. Plants are“factories”.They make food from sunlight, water and things in the soil and air.

    Plants feed all other living things. Animals can only use the sun’s energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.

    What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruits and so on. We also eat meat and drink milk. But men often break up the food chains. They kill wild animals. They also make rivers, lakes and seas dirty. When these rivers, lakes and seas are polluted, the fish in them cannot be eaten. If men eat the fish, they will get strange diseases.

    Each form of life is linked to all others. Breaking the links puts all life in danger.
