Return to the moon

It might not be long until humans uncover the secrets of the far side of the moon. China’s Chang’e 4 robotic probe (探测器), which is set to become the first probe to land on the moon’s far side, was launched successfully on Dec 8, Xinhua reported.

The moon rotates (自转) at the same speed that it orbits (运行) Earth. Therefore, the same side of the moon always faces Earth. The far side of the moon is the side that we cannot see. We don’t know much about it so far.

However, the far side of the moon is an ideal (理想的) place for scientific research(研究). It is exposed (暴露) to solar winds that may have formed unique minerals (矿物质) and other resources. And since the far side is less affected by Earth’s gravity, scientists can make clearer observations of deep space from there, according to China Daily.

But it is hard to land on the far side of the moon. Spacecraft that land there cannot receive any radio signals(信号) from Earth. To solve this problem, China launched a relay satellite (中继卫星) called Queqiao into space in May. Through Queqiao, scientists can control and operate Chang’e 4 and make sure it will land in a specific(特定的) area.

The probe’s travel time is also important. Chang’e 4 is expected to land on the moon on Jan 2, China Daily reported. It will travel through space for more than 20 days before landing. This is longer than Chang’e 3, which was in space for about 12 days before landing.

The travel time was changed because scientists want Chang’e 4 to land on the moon when it is daytime. This way, the spacecraft’s solar panels ( ) can receive energy from the sun and allow the probe to start working. A single day on the moon is about 28 days on Earth. Therefore, Chang’e 4 will keep orbiting the moon before landing as it waits for daytime, according to Sun Zezhou, chief designer of Chang’e 4.

Did you know? Chang’e 4 took some plant seeds and eggs to the moon. It was hoped that Chang’e 4 was able to do experiments with them. These were the first biological experiments to take place on the moon.

1Is Chang’e 4 the first probe to land on the far side of the moon?

2What does the far side of the moon refer to(指代)?

3Why does the same side of the moon always face Earth?

4How did Chinese scientists solve the problem of no signals?

5Why do scientists want Chang’e 4 to land in daytime?

【题目】阅读短文, 根据短文内容回答问题.

Life in the 22nd century will be different from that in the 21st century, because many changes will take place.The population is growing fast.There will be more and more people in the world and most of them will live longer than before.Computers will be much smaller and more useful, and there will be at least one in every home.And computer studies will be one of the most important subjects at school.

People will work fewer hours than they did in the 21st century, and they will have more free time for sports, watching TV and traveling.Traveling will be much easier.And more people will go to other countries for holidays.

There will be changes in our food, too.More land will be used for building new towns and houses.Then there will be less room for cows and sheep, so meat will be more expensive.Maybe no one will eat it every day; instead they eat more vegetables and fruit.In this way people will be healthier.

Work in the future will be different, too.Robots will do dangerous and hard work.Because of this, many people will not have enough work to do.This will be a problem.
