Antarctica is in the most southern part

题型:阅读理解

问题:

Antarctica is in the most southern part of the world. It is like nowhere else on the earth. It is much larger than Europe, and nearly twice the size of Australia. Antarctica is the coldest and windiest place in the world, even colder and windier than the North Pole. In summer, the sun shines for twenty-four hours a day, but in winter it’s completely dark for about three months. Very few plants grow there, but there is some wildlife, including whales, seals and penguins.

When Captain James Cook traveled around Antarctica in the 1770s by ship, he found no one living there. Today, a few scientists work in Antarctica, but they only spend a short time there.

Many scientists are studying the ozone layer, which is getting thinner and thinner worldwide. The biggest “hole” is above Antarctica, and weather there is getting warmer. Scientists think that this cold and lonely place can teach us a lot about the earth and how to keep the earth safe.

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(前苏联) 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.

小题1:Which of the following has the closest meaning to the underlined word “observed” in Paragraph 2?

A.Discovered

B.Checked

C.Watched

D.Fixed小题2: What can we infer(推断)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.小题3:What is the best title of this passage?

A.Exploring Space

B.Space Travel

C.Living in Space

D.Space Stations
