Summer on Uranus lasts for 42 years.During this time it is     9     on the other side of the planet.The sun shines on each side for 42 years at a     10     as it goes around the sun.

3 . 2018年12月30我国自主研发的嫦娥四号月球探测器号升空，2019年1月3号在月球的背面着陆。通过它持续的发回照片、完成探测、实验的任务，它帮助我们更多的了解月球的背面。有趣的是此次嫦娥四号上还搭载了六种生物。请用英语将下面的这篇新闻报道补充完整。

Every time we see the moon, we can only see one side of it. The other side we cannot see is called far side of the moon（月球的背面）    1    scientists. It is a mystery to us. Now Chang’e 4 may    2    us learn more about it. Chang’e 4 is a probe (探测器). It left the earth on    3    30. It landed    4    on the far side of the moon on January 3,2019. It is the first probe in the world to do so. Chang’e 4 took six    5    things to the moon. Cotton, potato and fruit flies are some of these things.

5 . As space science develops, man has learned more and more about space. Space is not only a    1     but also dangerous. While working in space, spacemen are facing danger as well as s    2    .

Scientists have found out that the in radiation(辐射)is the greatest danger to spacemen. When spacemen are working in space, they are in d    3     of the radiation from the sun and other stars, which is bad for their health. The h    4     of the radiation won’t be found until their children even grandchildren are born. Some s    5     medicine may work a little, but no really effective medicine has been found so far.

Space r    6     is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are s    7    , and the rest are space rubbish. An explosion(爆炸)in space in 1999 made a cloud of 300,000 fragments (碎片), each at least 4mm in size. A small piece of these even knocked a spaceship window and c    8     some damage（损 坏）.

Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. A    9     space is really dangerous, it interests many people on the Earth. In the near future, it may become possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should do something to help i    10     the space environment.

The sun is much n    5     to us than any other star. That is w    6     it looks the biggest and brightest of all the stars. The distance (距离) of the sun from the earth is as m    7     as 150,000,000 kilometers. Most stars are thousands of light-years a    8     from the earth.

Do you know what a light-year is? N    9     in the world travels faster than light. It travels 300,000 kilometers per second. And one light-year is the distance that light can travel in one y    10    .
