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 as well as success．
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 may work a little, but there is no really helpful medicine．
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 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 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 Earth and live in space in a few years．So we should care for space and do something to help improve the space environment．

You will have a lot of reading to do in this grade this year．You can do more of it in less time if you learn to read rapidly．
Perhaps you have been told about some habits (习惯) which keep a person from reading fast and have been strongly asked to break those habits which you might have．
Do you still have any of these bad habits?Check yourself by answering“yes”or“no”to these questions．
(1) Do you move your lips (嘴唇) when reading silently?
(2) Do you point to words with your finger as you read?
(3)Do you move your head from side to side as you read?
(4)Do you read one word at a time?
If you answer“yes”to any of these questions,start at once to break the habit．If you move your tips，hold your fingers over them，or hold a piece of paper be-tween your lips while you are reading．Then if your lips move，your will know it and can stop them．
If you point to words，hold the two sides of your book，one side with your left hand，the other side with your right hand．Then you won't have a free finger to use in pointing while reading．If you move your head，place your chin (下巴) in one hand and hold your head still (静止不动的)．
If you read no more than one or two or three words at a time，you need to work very hard in learning to take in (吸收) more words at each glance (一瞥) as your eyes travel across the lines of words．
Even if you do rather fast now，you can learn to read even faster．As you probably have been told，the secret of fast reading is to take in whole groups of words as each glance．Read in through groups and force (迫使) your eyes along the lines of words as fast as you can to make them go．Anyone who practices doing these things will he able to read faster．
