点选一句，句末即可听读；连起意思，大声读一遍。
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 will grab 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.

1990年4月20日，美国国家航空航天局把哈勃望远镜送入太空，耗资超过十亿美元。 可哈勃一开始就出了问题，传回来的图像很令人失望，原来是主镜出了毛病！ 美国国家航空航天局准备把它修好，很快就会派四名宇航员上去，由“奋进”号航天飞机把他们送到哈勃旁边。 “奋进”号上的机械臂会抓住望远镜，将它固定住，让宇航员完成必要的维修。 当然，哈勃位于地球大气层之外，修好后很快就会传回恒星和遥远星系的图像，清晰程度前所未有，还能帮助我们更多地了解宇宙的年龄与大小。 等你读到这里，哈勃这只“鹰眼”应该已经传回成千上万张精彩的照片了。
学完这一课
先沿这条线复述《哈勃望远镜的困境》：昂贵的太空发射 → 一开始就有故障 → 派宇航员去修理 → 机械臂配合维修 → 期待清晰图像和新知识 → 把目光投向未来。再借一个结构讲自己的事：把课文的未来安排改成自己明天某个时刻的安排。
