The question whether there is life on Mars (火星) has made the public think a lot for more than a century. The closest look showed Mars to be a dusty, cold world, covered by air too thin to breathe. A British spaceship and Europe's Mars spaceship plan to land on Mars or enter orbit (轨道) around it. One of the NASA’s (美国宇航局) spaceships is expected to land on January 3, the other is going to land on the opposite side of Mars on January 24. Since 1960, over twenty spaceships sent to Mars have failed. Most have been lost on flying up or landing because those are the most difficult times of any flights. Scientists wanted to find out whether there was water in Mars. In October, a team of scientists reported that Mars had been a dry wasteland. But weeks later, a second team reported differently that they had found some marks showed clearly that they were made by the rivers. Such marks told us that Mars was a warmer place billions of years ago — just as life first appeared here on Earth. Scientists at once raise a question: if what they said is true, what happened on Mars? Then what about the earth?

1.Which is right about Mars?

A.It’s cold without dust.

B.There is no water or air.

C.It’s warm with some thin air.

D.It’s a dusty, cold world almost without air.

2.Two NASA’s spaceships _______________.

A.will land on the different sides of Mars

B.will land on the same day

C.will enter orbit around Mars

D.will land with a man

3.The most difficult times of a flight are _______________.

A.taking off

B.flying up and arriving

C.entering the orbit and landing

D.leaving the earth and entering the orbit

4.A team of scientists reported that there might be_____________ in Mars.

A.nothing but air

B.nothing

C.water billions of years ago

D.thick air and lakes

5.What are scientists worried about when they raise the question?

A.Life disappeared on Mars.

B.Spaceships can’t land on Mars.

C.The air on the earth gets less and less.

D.The earth might be changed like Mars

There is more than one way to find out whether or not you are in the right field, or working at the right position. If you hate going to work each day, and are worried about the weekend’s end, it is one sign; but, there are other signs that you are bad at your job.

1. You always get left out

If you find that you can’t fit in with anyone who works in the office, it might not be the right place for you to work. If so, it is time for you to start looking elsewhere, because you might not be suited for what you are doing now.

2. You never get work to do

If you work with a larger team, but you are never chosen as a team leader, or even part of a team, it may be a sign that you are not great at your job.

3. You don’t get raises

When all other employees (员工) get a 1% annual pay (年薪) increase, or higher, yet you have had the same salary (薪水) for a few years, it may be a sign that you are just getting by. A raise is your boss’s way of thanking you for your hard work, and great service. If you never receive a raise, it may be their way of letting you know that you are not doing work to a satisfactory level within the organization.

1.If you can’t fit in with anyone working in the office, you’d better ________.

A. try hard to please them　　 B. start looking elsewhere

C. stop your work at once　　 D. go to look for your boss

For people who are interested in space, nothing is more exciting than the idea of living on other planets. That might be why the movie The Martian is so popular. It shows an astronaut living on Mars. But would it really be possible to live on the Red Planet?

While the idea of living on Mars is great, the reality does not look as good. Mars does not have a friendly air for humans. There is very little oxygen(氧气) there. And because it's far from the sun, it is also very cold. The temperature on Mars can be ­62 on average. This is much too cold for humans.

However, scientists say it might be possible to live there even without a good air. Daytime on Mars is almost the same as Earth's. It means there's enough sunlight to grow plants inside safe buildings. However, they would have to grow in soil from Earth. Mars does not have a strong enough air to stop the radiation(辐射) coming from space, which makes it dangerous to grow things in the soil.

The radiation also causes problems for our health. One way we could live there would be to build homes under ground or within the rocks on the planet. This would give humans the protection(保护) from the radiation and also some heat.

When could we live on Mars? NASA is hoping to make some progress within the next 20 years.

1.Which of the following about Mars is TRUE?

A. Its air is good for humans.　　 B. It has enough oxygen on Mars.

C. It's a little colder than Earth.　　 D. It's not close to the sun.

2.Why is it possible to grow plants on Mars?

A. Because there is enough sunlight.

B. Because the soil is good on Mars.

C. Because it has little oxygen there.

D. Because it has the strong radiation.

3.What's the passage mainly about?

A. How to grow plants on Mars.

B. How to live on Mars without danger.

C. How to keep warm on Mars.

D. How to improve the air on Mars.
