·課文

????The Hubble telescope was launched into space by NASA on April 20,1990 at a cost of over a billion dollars. Right from the start there was trouble with the Hubble. The pictures it sent us were very disappointing because its main mirror was faulty! NASA is now going to put the telescope right so it will soon be sending up four astronauts to repair it. The shuttle Endeavour will be taking the astronauts to the Hubble. A robot-arm from the Endeavour willgrab the telescope and hold it while the astronauts make the necessary repairs. Of course, the Hubble is above the earth’s atmosphere so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen. The Hubble will tell us a great deal about the age and size of the universe. By the time you read this, the Hubble’s eagle eye will have sent us thousands and thousands of wonderful pictures.?

????·and 連接詞，hold 原本應(yīng)該是 A robot- arm from the Endeavour will hold，給省略了，所以單看 hold 以為是動(dòng)詞原型，一般現(xiàn)在時(shí)，其實(shí)是一般將來(lái)時(shí) will + 動(dòng)詞原型

????·而 while 是時(shí)間狀語(yǔ)從句，想用將來(lái)時(shí)要替換成一般現(xiàn)在時(shí)，所以 make 動(dòng)詞會(huì)是原型
