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 dangers as well as interests. 

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(危害)done by radiation won't be discovered until their children or even grandchildren are born. Some special medicine works a little, but no really helpful medicine has been produced. 

Space junk(垃圾)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 satellites, 10% are spaceships, and the rest is space junk. 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 or live in space in a few years. So we should care for space and do something to help improve the space environment.

①As missing children get older,they become quite different from the faces in their last﹣known photographs,which makes finding the really difficult. Now AI(人工智能)can make it easier to match any found children to those old photos. 

②Police can use software(软件)to age photos of missing people,but it seems to work best in adults

③Unlike adults ,the faces of children change greatly as time goes by,and matching photos of found children to old images(画像)(数据库)of missing children is difficult. "Even with a recent face image of a child,it is quite hard for a human to recognize(辨认),who the child is from a large data set of child face images," says Debayan Deb at Michigan State University. 

④Now Deb and his teammates have created an algorithm(算法)to work out the problem. They created a face﹣recognition algorithm on data sets,which have images of nearly 1

⑤AI learned to match recent photographs of children with images taken 2. 5 years earlier. The correct matching rate can be 80 percent. With one year between the two photographs,it was 90 percent correct at recognizing faces. This dropped to 73 percent after three years. The new AI might help to improve accuracy (准确性)of this kind of software

⑥Deb's next goal(目标 )is to make the age gap wider. His team also hopes to develop an app to fight against the sale of children.
