Have You Got the Time?

People today are always thinking about the time.

There never seems to be enough time to do all the things we want to do. Believe it or not, there was a time before time was so important.

3 . 阅读短文，根据要求完成下面各小题。

Earth (地球) is a planet and Mars (火星) is too. People, animals and plants live on Earth, but can they live on Mars? Earth has water. But what about Mars?

People want to find out about other planets like Mars. So Robot Landers have been made (被制作) to help them. This Lander was one that went to Mars. It has a long arm with a camera on it.

The Lander is inside this spacecraft (宇宙飞船). The spacecraft blasts into space. It will take a long time to get to Mars. When the spacecraft is there, the Lander comes down to land on Mars.

The Lander is on Mars. Mars looks like a desert on Earth but it is very cold. Now the Lander has a job to do.

The Lander digs (挖) in the ground to get soil (土壤). People on Earth look at the soil. What is the soil like? What is under the soil? Is there water here? The Lander helps people on Earth to find out.

The sun is going down. Night will come to Mars. The sun helps the arm on the Lander to move. When there is no sun, the Lander will not work.

People can go into space. They can walk on the moon, but can they go to a planet like Mars?

Robot Landers like this one can help people find out.

4 . Dear Peter,

I hope everything is going well. I have something very special to tell you. Last week I went into space for the first time!

My parents visited space last year, but I was too young to go with them. Anyway, a month ago, I had my birthday party. It was very exciting when I opened my p    1    . There were lots of wonderful games, but I was really h    2     when I saw a ticket for a space flight!

Two weeks after my birthday, I had to go on a short training course. It was quite difficult, and I had to study very hard. L    3    , I got a good mark in the exam in the end, and my parents were able to book the date of the space flight, I started to look forward to that day.

Finally, the day arrived, and my parents took me to the a    4    . I got on the plane with another ten passengers. We took off from the runway and climbed got on higher and higher. After about an hour, we went down from the plane into the shuttle((航天飞机). The plane then dropped the   space shuttle at very high altitude(高度).The engines in the space shuttle started, and thirty minutes later we were in space.

I admit that for a few seconds I felt a little nervous when I sat in the space shuttle. However, when we l    5     the Earth’s atmosphere(大气层）, everyone began to float(飘浮). It was great fun! I felt so free in space.

My first space flight only lasted fifteen minutes, but I will never forget it. I a    6     have some good news for you. My parents say they want to go back into space next year. They say I can bring a friend. Would you like to come with us? I hope to hear from you soon.

Yours

Mark
