1 . As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger.
Scientists have found out that radiation(辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. The damage done by radiation won't be discovered until their children or even grandchildren are born. Some special medicine may work a little, but no really helpful medicine has been.
Space junk is also thought a great danger to spacemen. It's reported that there are 9,000 man-made things flying in space. About 30% of these are man-made satellites(卫星), 10% are spaceships, and the rest are space junk. An explosion(爆炸) in 1996 made a cloud of 300,000 fragments, each at least 4mm in size, and even a small piece of these knocked against a spaceship window and did some damage. Scientists are watching and reporting any possible danger all the time. They are working on helpful ways to do with space junk.
Although space is really dangerous, it interests everyone on the earth. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space for a few years. So we should care for space and do something to help improve the space environment.

An Exciting Trip
Thousands of years ago, Chinese poet Qu Yuan (about 340-278 BC) wrote the poem Tianwen, meaning Quest for Heavenly Truth. He came up with a series of questions about the sky, stars, nature, myths and the world around us. The poem showed his doubts about traditional ideas and the spirit of finding the truth.
Inspired by the great poet, China has named its upcoming series of planetary exploration missions (行星探测任务) after the poem. The first one in the series-a Mars exploration mission-has been named Tianwen 1, the China National Space Administration (CNSA) said on April 24, China’s Space Day. This shows China’s desire (渴望) to explore the universe and discover its secrets.
China has been making great progress in space exploration. As early as 1970, China launched its first man-made Earth satellite (卫星), becoming the fifth country in the world to launch a man-made satellite independently. Since 2003, China has carried out six Shenzhou manned missions and launched two space labs into Earth’s orbit (轨道). China’s moon exploration missions-the Chang’e series-started in 2007. In December 2018, China became the first country to send the probe (探测器) Chang’e 4 to the moon’s far side, which always faces away from Earth.
The Tianwen series will follow the Shenzhou and Chang’e series and move further into space. The first step is to launch a Mars probe this year, which will mark the start of China’s exploration of the Red Planet. The probe is expected to orbit (绕……轨道运行), land on and explore Mars in one mission. If it succeeds, it will be the first to complete all of these tasks in one mission. The Long March 5 rocket will send the probe to Mars. It will take seven months to reach the planet and land.
After this mission, China plans to visit Mars again in 2028, aiming to collect soil from the surface of the planet and bring it to Earth. Around 2030, China will explore Jupiter and several asteroids (小行星), according to CNSA.

10 . Shlander is a man from space. He thinks the people and things on the earth are very strange. He is now writing a letter to his friend at home. Here is part of his letter. Read it and answer the questions.
Now I am in a strange world. It is very nice. There are many new things here. There are many earth monsters here, too. The earth monsters look very funny. They have just one head, two arms and two legs. They have thin black strings on their heads. Some earth monsters have brown or yellow strings. The earth monsters have a hole in their face. Every day, they put nice things and balls from the trees into the hole. They put water into the hole, too. The earth monsters do not walk very fast. They move from place to place in tin boxes.
At night, the earth monsters like to look at a square window box. This box has very small earth monsters in it.
