Scientists think that there has been life on the earth for hundreds of millions of years. However, we haven't found life on other plants yet. Why not?
The Earth is a planet and it goes around the Sun. Seven other planets also go around the sun. None of them has an environment with air, so people and living things cannot grow. The Sun and its planets are called the solar system(太阳系). The solar system is a small part of our galaxy(星系).
But scientists have discovered many other galaxies in the universe. But they are far away and their light has to travel for many years to reach us. It is hard to understand how large the universe is.
So far, scientists have sent lots of spaceships to look at other plants in our solar system, and some spaceships have gone beyond the solar system. However, no one has discovered any life in space yet.
But why has no one from other plants sent us a message? Have they tried to send information to us? With so many stars in the universe, are we alone, or is there life out there in space? We don't know yet.

Mr. Guo is a teacher from Xi’an. He asked his students to hand in their homework through a QR code(二维码). “We spent an hour or two in class learning how to generate(使产生)the codes, and in the end everything gets easier.” Said Guo. “When students finish the homework, they keep in on WeChat(微信). Then, each student makes his own QR code and gives it to me. So I can check their work everywhere using my computer or telephone.”
The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Guo scans(扫描)his students’ QR codes, their homework appears on his phone. He finds that their homework becomes more creative(创新的), with many pictures, music and even videos.
Guo’s students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun.” said Tingting, a student of Guo’s.
“The paper is not easy to keep, but the code is easy to keep and share,” Guo said. “It is worth trying to use new technology in education. Education itself is a kind of creation. I don’t want my students to fall behind the times.”
However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it’s unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the code when they hand in their work, which doesn’t take them too much time. Also for teachers, it allows them to check the students’ work at any time. And it’s also an easy way to share homework with other students.

There were many sick monkeys, and Dr. Dolittle was very busy curing them.
He separated the sick monkeys from the well ones.He gave shots to all the monkeys that were well so that they wouldn't get sick. Then he asked them to build a house and make beds for all the sick monkeys. He put all the sick monkeys in this house.
“I need more nurses, ”he said. “Ask other animals in the jungle to come and help.” At first, the other animals did not want to help. The King of the Lions said with a roar, “I'm not going to nurse monkeys.” The doctor tried hard not to seem afraid of him. He said,“ One day you may be ill.

That night, one of his children felt sick.“ He won't eat,” the Queen Lioness said to the King of the lions.“ You must do something.”“ There's nothing I can do, ”the King of the Lions said.“ A lot of monkeys are sick, too. Do you know, there's a man who asked me to nurse them. He’s some kind of doctor. Huh! I told him that lions didn't nurse other animals.”
