1 . 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Do you know anything about the Moon? How much do you know about it?

    1    ? Scientists tell us so much about the Moon. So it’s easy for us to have the idea of going to the Moon. But what would it be like to really go there?

The Moon is not a friendly place. There is no air or water. There are only lots of dust (灰尘) and mountains around on it.     2    . The temperature (温度) of the Moon is different from day to night.     3    . But it’s very cold at night.

    4     As we know, sound can only travel in the air but there is no air on the Moon.

So people can’t hear any sounds on it.

But from the Moon, you can see our beautiful Earth. It is shining more brightly than the other stars in the dark.     5     The photos would be wonderful.

A．So there are no animals or plants there

B．The Moon is also a very quiet world

C．Do you want to go to the moon

D．You can take some photos with your camera

E．When the Sun shines in the day, the temperature is very high

F．Will you be hungry in space

G．Let’s see an exciting film about space

3 . It is widely agreed that the overuse of coal and oil has caused serious environmental problems. Scientists are trying to find new clean energies that do not pollute the air, the water or the ground. Solar power(太阳能)is one of them.

Solar power is a kind of electricity which is produced by taking energy from the sun, using solar panels(面板，电池板). The power is easy to get and will never be used up. Whenever it is sunny, there is the power. The power is clean and renewable. It helps to reduce waste and pollution, which is great for the environment. For some areas that are too far away to send electricity to, solar power is especially necessary. People there use solar power for lights, TVs, computers, washing machines, fridges and many other things.

Therefore, more and more countries, such as China, the USA, Japan and India, encourage scientists to develop practical(实用的)technology to put solar power to use. However, the power is not as widely used as expected(预期的).

One of the challenges(挑战)is that a solar power system needs sunshine. Countries or areas with a lot of rain, like the UK, are not suitable to develop such power systems(系统). Secondly, a solar power station requires a very large site(地点)to fix(安装)enough solar panels to collect sunlight and change it into electricity. What’s more, solar panels are expensive at present though the energy itself doesn’t cost anything.

Today scientists are working hard to develop more practical and cheaper solar power systems. Maybe one day solar power will be one of the most important clean energies in our life.

1. Solar power is a kind of energy taken from ________.

A．the air

B．the sun

C．the water

D．the ground

2. The underlined phrase “be used up” means ________.

A．短缺

B．滥用

C．用完

D．习惯

3. Why isn’t the solar power used widely?

A．Because a solar system needs sunshine.

B．Because solar panels are expensive.

C．Because fixing solar panels needs very large sites.

D．All of A, B and C.

4. What is the main idea for the Paragraph 4?

A．The ways to use solar power.

B．The advantages of solar power.

C．The places to build the solar power stations.

D．The difficulties of putting solar power to use widely.

5. What can we learn from the passage?

A．Solar energy itself is expensive.

B．Solar power will be used up very soon.

C．Solar power is a kind of clean and useful energy.

D．Solar power is much better than the other energies.

6 . If you look at the sky one night and see something moving and shining that you have never seen before, it might be a comet (彗星).

A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects (反射). Like the earth, a comet goes round the sun, but on a much longer path (轨道) than the earth travels.

If a comet isn’t a star, what is it then?

Some scientists think that a large part of a comet is water frozen into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail.

Many people perhaps have seen a comet. However no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see.

An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley because he was the one who worked out when it would come back again. Maybe you have ever seen Halley’s Comets because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley’s Comets when it comes near the earth again.

A．sun

B．star

C．planet

C．have seen a comet at daytime	D．have seen a comet

A．in 1990

B．in 1980

C．in 1986

D．in 1989

Are we alone in space? Is the Earth the only planet that has life?     1     Now we may get one step closer to the answers.

On Feb. 22nd, NASA said they found seven Earth-like planets.     2     The planets go around a dwarf star（矮星）called Trappist-1. It is much smaller and cooler than our sun. They are about 39 light-years（光年）from the Earth.     3     But scientists say it’s a little close.

    4     If you lived on one of them, you could possibly see the clouds around the next planet. More importantly, three of the planets are at the perfect distance（距离）from the Sun.     5     If there is liquid water（液态水）, there could be life.

For scientists, the finding is not an end. Next, they will try to find out if the planets have atmospheres（大气层）.

A．It means there could be liquid water on them.

B．That seems too far away from us.

C．These are big questions in the science world.

D．The seven planets are very close to one another.

E．They all nearly have the same size as Earth.
