难度类似科三笔阅读难度的新2第61 哈勃望远镜的困惑
The Hubble telescope was launched into space by NASA on April 20,1990 at a cost of over a billion dollars.
***********生词 launch 这里是被动语态 at the cost of , at the sight of一看到 at the thought of 一想到 是用一个介词短语词组代替从句的用法
Right from the start there was trouble with the Hubble.
*********Be trouble with 比较be trouble doing sth.
The pictures it sent us were very disappointing because its main mirror was faulty!
*********** disappointing disappointed 区别。 生词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 will grab the telescope and hold it while the astronauts make the necessary repairs.
************ 这里的grab ,hold, necessary 在青少3a的14单元,5单元都学过
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.
************atmosphere,大英和四口词汇。Distant是遥远 we have ever seen 是常用语做定语从句。
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.
**************** a great deal 大量(不可数) 将来完成时 ,类似 “将建成,将发送完,将圆满结束”等的表达,
By 这里是在某个时间之前
