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.

A.earthquakeB.debrisC.dustD.landslide
小題2:The purpose in writing this text is _____
A.to tell people how serious the damage caused by landslides is
B.to tell people that sending workers to stabilize mountainsides is a dangerous job

Space travel is nothing new. The first spacecraft with a human was sent up into space in 1961. Since then, people have not only traveled to space, but also many of them have lived there in space stations for some time.
The Soviet Union(前蘇聯(lián)) sent the first space station into space in 1971. This space station was called Salyut 1. Salyut 1 was designed as a place where people could live while they observed space and did experiments. The first group of astronauts lived there for 23 days. The Soviet Union went on to make seven more Salyut space stations. At about the same time, the United States built its own space station, called Skylab.
Astronauts visited and often lived in these space stations for a short time. However, it wasn’t until the late 1980s when The Soviet Union sent the Mir space station that people began to live in space for a longer time. Mir stayed in space from 1989 until 2001, when it was decided that the space station was too old and no longer safe to live in.
Living in space stations seems to be fun, but astronauts face many problems. One of them is food. All the meals on space station are put together on Earth and sent there by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be stored in cans. The space station does not have a fridge, but it has a cool room to keep fruit and vegetables fresh. Astronauts also eat many other foods such as dried meat that do not need special care.
Without the help of gravity, sitting down to eat can be tough. Astronauts sometimes have to fix themselves to the wall while eating. They also have to be very careful to that food does not float away.
小題1:Which of the following has the closest meaning to the underlined word “observed” in Paragraph 2?
A.DiscoveredB.CheckedC.WatchedD.Fixed
小題2: What can we infer(推斷)from the passage?
A.Astronauts can never have a chance to eat fresh food when they live in space station.
B.The Soviet Union sent a total of 9 space stations into space in the 1970s and 1980s.
C.Astronauts could live in the Mir space station for no more than three weeks.
D.Space travel has quite a long history of more than 60 years.
小題3:What is the best title of this passage?
A.Exploring SpaceB.Space TravelC.Living in SpaceD.Space Stations

Now satellites(衛(wèi)星)are helping to forecast the weather. They are in space and they can reach any part of the world. The satellites take pictures of the atmosphere(大氣), because this is where the weather forms(形成). They send these pictures to the weather station. So meteorologists(氣象專家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare(比較)them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon, perhaps , they may forecast the weather for a week or more ahead(提前)
小題1:Satellites travel__________.
A.in spaceB.in the atmosphere

Many animals do strange things before an earthquake (地震). This news may be important. Earthquakes can kill people and knock down homes. The animals may help to save lives.
Some animals make a lot of noise before an earthquake. Farmers have told about this. Dogs that are usually quiet have started to howl(吠). Horses on farms have run around in circles. Mice have left their holes and run away. Cows have given less milk.
In a town in Italy, cats raced down the street in a group. That happened only a few hours before an earthquake. In San Francisco, a man kept tiny pet frogs. One Sunday, the frogs jumped around more than ever. They made loud noises, like bigger frogs. That night, an earthquake struck the city.

The Xin’an Street Community(社區(qū))began three programs not long ago.
The Neighborhood Clean-up Program
Every Sunday at 5:00pm, the neighbors begin cleaning Xin’an Street from one end to the other. The head of the Community, Zhao Fuqin, said, “The first Sunday, only eleven people came, but we picked up over seven big bags of rubbish (垃圾)from the sidewalk and street. The next weekend, twenty people came, and filled eight rubbish bags. Now the neighborhood really looks great!”
The Neighborhood Watch Program
The neighbors on Xin’an Street began this program to look for problems in the neighborhood and to call the police if necessary. The neighbors all say the watch has already helped.

Now I know my neighbors are watching for trouble. ” According to the police, there are fewer problems on Xin’an Street. “Calls to 110 went down last month. Criminals knew that the people on Xin’an Street were watching, so they stayed away,” said a policeman.
