V.阅读与表达（第1一3小题每题2分，每4小题4分，满分10分） 阅读短文，然后根据内容回答问题。 Have you ever dreamed of being an astronaut?Can you imagine what astronauts do in space? When astronauts are in space,they eat,sleep,wash,work and play.They do the same things as us on Earth,but they do them differently.That is mainly because there is almost no gravity in space.On Earth,we put food on a plate and water in a glass.Gravity holds the food down and keeps the water in the glass.But in space,food floats away,and astronauts must eat and drink carefully. Sleeping is very difficult in space.Some astronauts like to float in the air,but most like to be in sleeping bags..They attach(把…固定)the bags to a wall.. Washing is difficult,too.There is no shower or bath,so astronauts just use towels( 巾). Exercise is very important in space.On Earth,your legs carry your body,but in space,astronauts float,so they do not use their legs.This is very bad for their legs,so they have to exercise for thirty minutes every day.They often use an exercise bicycle for this. After a day's work,astronauts relax.They may listen to music,read books,watch films,play games or talk to their friends and families by radio.On the International Space Station,astronauts sometimes move from one end of the station to the other.Another thing they do is looking out of the window,looking at space and watching the Earth. 1.Why do astronauts do things differently from us in space? 2.What do astronauts use for washing? 3.How long should astronauts exercise every day? 4.Do you want to be an astronaut?Why?(Write 30 words or more. ·34· 英语·七年级·上册W班级： 姓名： 得分： Section 2 Grammar 工.回归教材·练词汇（每小题2分，满分20分） 根据句意和汉语提示写出单词。 1.Scientists are trying to predict the (未来)of our environment. 2.Our team has a strong knowledge (基础).SoI'm sure we will win the game. 3.The little boy was so excited that he told the （全部的)story to his friends. 4.I can enjoy (of the park through my window every morning. 5.The art exhibition displayed three different (形式)of traditional painting. 6.Ice cream is (肯定)the best in summer! 7.I often visit educational (网站)to find information for my homework. 8.He was so clever that he thought out a (绝妙的)solution. 9.Susan keeps a (日记)and writes down what happens every day. 10.It's amazing that (宇航员)can grow vegetables in space!
