Question

【题目】

There are lots of objects that we see in the sky. During the day we see the sun. After the sunset in the evening, we see mostly the stars. Not all the lights in the sky that we see are really stars.

Of course, we see the moon. Some of the other lights in the sky are planets. Planets revolve (转动) around the sun like earth does.

Once in a while someone will see what they call a shooting star.

Shooting star looks like a star that is moving quickly across the sky. Some people believe that seeing a shooting star will bring them good luck. It’s hard to find shooting star because they disappear fast.

The correct name for a shooting star is meteor. Besides very large objects like stars, planets and moons, space has lots of little objects. These can be rocks in space left over from old planets.

These objects can even be as small as dust.These objects are called meteorites(陨石 ).

When a meteorite gets close to the earth, it gets pulled towards the earth by gravity. Earth is surrounded by atmosphere. Atmosphere is made up of air and clouds. A meteorite blows up in the earth’s atmosphere. This makes the short bright moving light in the night sky. A meteorite thus turns into a meteor.

【1】At night the sky is filled mostly with ______.

A.the moonB.the starsC.the planetsD.the sun

【2】From the passage, we can know________.

A.all the lights in the sky that we see are really stars.

B.shooting star looks like a star that is moving slowly across the sky.

C.when a meteorite is near the earth, it gets pushed from the earth by gravity.

D.space has lots of little objects and they can be rocks left over from old planets.

【3】How does a meteorite turn into a meteor? Please put the following sentences in order.

①The blowup gives off bright light.

② It is pulled towards the earth by gravity.

③A meteorite gets close to the earth.

④It blows up in the earth’s atmosphere.

A.③④②①B.③④①②C.③②④①D.③②①④

【4】Where can we probably read this passage?

A.In a science magazine.B.In a diary.C.In an advertisement.D.In a novel.

Answer 1

【答案】

【1】B

【2】D

【3】C

【4】A

【解析】

本文主要讲了流星的形成。它是陨石靠近地球时被重力拉向地球，陨石在地球的大气层中爆炸，形成了流星。

【1】细节理解题。根据上文After the sunset in the evening, we see mostly the stars. 傍晚日落后，我们看到的大多是星星。故选B。

【2】细节理解题。根据上文space has lots of little objects. These can be rocks in space left over from old planets.太空中有很多小物体。这些可能是旧行星遗留下来的太空岩石。故选D。

【3】细节理解题。根据上文When a meteorite gets close to the earth, it gets pulled towards the earth by gravity. Earth is surrounded by atmosphere. Atmosphere is made up of air and clouds. A meteorite blows up in the earth’s atmosphere. This makes the short bright moving light in the night sky. A meteorite thus turns into a meteor. 当陨石靠近地球时，它就会被重力拉向地球。地球被大气层所包围。大气是由空气和云组成的。一颗陨石在地球的大气层中爆炸。这形成夜空中的短而明亮的移动光。陨石就这样变成了流星。故选C。

【4】推理判断题。A. In a science magazine.在一本科学杂志里；B. In a diary.在日记里；C. In an advertisement.在广告里；D. In a novel.在一篇小说里。纵览全文，主要讲的是流星的形成，这属于自然科学范畴，故选A。
