九年级英语单项填空中等难度题查看答案及解析

Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone.

And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.

We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised its tides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.

These small pieces have been going round the sun ever since. They are the planets.

1.Most stars are _________________________.

A. following a regular path in space

B. moving about without a fixed course

C. seldom wandering about in the universe

D. always travelling together

2.Some two thousand years ago, the mountain on the sun was raised probably because _____________.

A. the star moved away from the sun

B. another star happened to come near the sun

C. the sun and the moon raised the tides on the earth

D. a large tidal of wave travelled over the surface of the sun

3.The article suggests that _______________.

A. how space formed

B. our earth exists before the sun

C. no one knows where the earth comes from

D. our earth used to be a high mountain in the sun

4.The expression “the cause of the disturbance” refers to ________.

A. the large tidal wave            B. the powerful tidal pull

C. the star coming near the sun     D. one of sun’s planets

5. In the article, the writer mainly wants to tell us ______________.

A. where the planets in the universe came from

B. how the high mountains were formed on the sun

C. that the universe is so large that we cannot imagine it

D. why the tides over the surface of the sun were so powerful

九年级英语单选题中等难度题查看答案及解析

Space is a lonely place. Hundreds of thousands of kilometers from home, astronauts have a hard life. It stands to reason that, once in a while, they need to have a good cry. But this is a lot harder than it sounds.

We still know very little about space, and about living in zero gravity (重力). In fact, we are discovering new things every time astronauts take to the sky. As The Atlantic reported in January, crying is not all that simple in space. This is because when a person normally cries, gravity makes their tears move downwards. But in a spacecraft, this is not the case. Here, there is no gravity, which is why we so often see pictures of astronauts floating around. This means that, strangely, when you cry, your tears have nowhere to go. As a result, they just stick to your eyes.

In May 2011, astronaut Andrew Feustel experienced this. “Tears,” as he said, “don’t fall off of your eye...they just kind of stay there.” This can be quite painful. In space, your eyes get very dry, and the added moisture is annoying. Sometimes, things get even unusual. The astronaut Ron Parise told The Atlantic that when tears get big enough, they “break free of the eye and float around”.

No one can be quite sure why we cry. Why should water in our eyes have anything to do with feeling sad? If you stop to think about it, crying is a very strange thing indeed. And now, thanks to the wonders of space, it just got even stranger.

1.What’s the main idea of the first paragraph?

A. It’s hard to cry in space.

B. It’s easy to feel sad in space.

C. Living in space is lonely.

D. Nobody wants to live in space.

2.What will happen if astronauts cry in a spacecraft?

A. The tears will move downwards.

B. The tears will stick to their eyes.

C. The tears will go out of the window.

D. The tears will move upwards.

3.What does the underlined word “float” probably mean in this passage?

A. 静止　　 B.漂浮　　 C.盘旋　　 D.下沉

4.How will astronauts feel if tears are always in their eyes?

A. Sad.　　　 B. Comfortable.

C. Happy.　　 D. Uncomfortable.

5.What can we learn from the passage?

A. Our eyes usually feel very wet in space.

B. Gravity makes people’s tears move upwards in space.

C. People know about living in zero gravity very well.

D. Tears will float around if they are big enough in space.
