　　Can you imagine spacemen's everyday life in space? They also need to eat, sleep, exercise and relax．They do the same things as us, but they do them differently．

　　On Earth, we put food on a plate．Gravity(重力)holds the food down and keeps it on a place．But there is almost no gravity in space, so food can float away, and spacemen must eat carefully．

　　Sleeping is very different in space．Some spacemen like to float(漂浮)in the air, but most like to be in a sleeping bag．They tie the bag to a wall so that they won't float away at night．

　　Exercise is very important in space．On Earth, your legs carry your body, but in space, spacemen float, so they do not use their legs often．This is very bad for their legs, so they must exercise for thirty minutes every day．

　　After a day's work, spacemen relax．They may listen to music, read, watch films, play games, or　talk to their friends and families on the radio．Sometimes they just enjoy floating in the air．

　　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)．
