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.The underlined word “event” refers to_____

Look carefully at the back of a California state quarter．A man with a walking stick is pictured there．A bird called a California condor(大秃鹫)is flying overhead. Who is this man，and why is he so important that he is featured(处于显著地位)on the back of a coin?

As a young man，he spent much of his life exploring the beauty of the wilderness．He walked more than a thousand miles across the country，through fields and woods．John Muir liked writing about the places he visited，describing their beauty.
Muir also wrote about problems．In order to create more farmland for sheep and cattle, many trees were being cut down．This made Muir unhappy and worried，because he knew that trees were important to forests and to the animals that lived in them．Muir believed that nature should be conserved(保护)instead of being changed by human beings．He wrote articles in magazines and newspapers to spread the word about conserving forests．Soon，others began to listen．

Smoking in indoor public places including public working places, public transport vehicles and some other special outdoor working places has been banned(禁止)in China since January 2011.Let’s look at the following advantages of banning smoking.
First, banning smoking will not only help in saving smokers from health problems and diseases, but will also be good for passive(被动)smokers. When the smoker is smoking in a restaurant, the people around him are sure to breathe in the smoke and suffer from the diseases an active smoker gets. If smoking is banned, spread of these diseases can be controlled.
Next, banning smoking will put stress on smokers to give up. Since a smoker is prevented from smoking, he will learn how to live without smoking for long hours. When a smoker doesn’t smell or see anybody around him smoking, it might reduce his wish to smoke too. As a result, people have to give up smoking.
Smoking in public places influences non-smokers to start smoking, especially adolescents. When teens see people around them smoking, they will follow them easily. Thus the number of teen smokers will increase. Also asthma(哮喘)and other problems are often seen in children living around smokers. So if it is banned, these places will become safe for children and teenagers.
Looking from the economic point of view, smoking should be banned to increase work productivity(生产率).Employees(雇员)who smoke usually take breaks to smoke while working. So the number of hours they put in their work is smaller.
If you see from the environment point of view, smoking should be banned. Smoking causes air pollution. If it is banned, it will help keep the environment from getting worse.
________doesn’t belong to a non-smoking place.
| A．A field | B．A hospital |
| C．A library | D．A restaurant |
The second paragraph mainly wants to tell us ______.
| A．banning smoking is good for restaurants |
