The first computers were huge and expensive.They filled up almost the whole floor of large offices.Later,scientists found ways to produce cheaper and smaller computers.They invented chips(芯片)which made it possible to store more information in less space. Today,computers are not only cheaper,but also more compact.They can just be placed on top of an ordinary writing table.They can even be carried from place to place easily.Computers are not only used in offices by companies,but are used at home by families who can afford them. Robots are only moving parts controlled by computers.A robot can do the same work as a person for 24 hours without complaining(抱怨)or getting tired. In Japan and some places in America,robots are used in factories to assemble(装配)cars.As computers become more and more common in businesses and factories,people fear that one day computers and computer-controlled robots will put human workers out of work.

Blood is made up of different parts，such as red blood cells(红细胞)，white blood cells and platelets(血小板). Two chemical molecules(分子)on the red blood cells make people’s blood different.Scientists mark one molecule “A” and the other molecules “B”.According to which and how many molecules are on the red cell，scientists divide blood into four types: A，B，AB and O. Scientists have been wondering if there are some links(联系)between people’s blood types and their personalities(性格)，but they don’t know for sure yet. But some say that people with the same blood type may have things in common. People with type A: They look peaceful from the outside.But they ask too much of themselves so that they may be very nervous inside.They get happy or sad easily.Sometimes they are shy but always very careful.They can easily win people’s trust. People with type B: They have strong minds.Once they start a task，they don’t give up easily.They’ll try their best to finish it and do it well.Type B people always try to make themselves different from others.They want to do things in their own way. People with type AB: They are maybe the strangest among all blood types.They can be both open and shy，noisy and quiet at the same time，They are responsible and always ready to help others. People with type O: They are open and good at making friends.They always start tasks but don’t always finish them.They have lots of new ideas and love to be the center of attention.They always strongly believe in themselves.

It was not until the sixteenth and seventeenth centuries that scientists found the answers to some important questions.④With the help of Galileo’s telescope,people could see the sky more clearly,and find the positions of the stars and planets.Finally in 1665,Isaac Newton explained to the world what gravity(重力)was and people at last understood why they did not fall off the earth. 21.在文中①处填写一个单词，使得句意完整、上下文通顺。 ________________________ 22.根据文章内容回答问题。 What questions did early men ask themselves when they looked at the night sky?Write down one of them. _______________________________________________
