Lesson61 Trouble with the Hubble
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.

练习感悟：单词量比较多的课文，多为多音节的单词，比较难读，特别是shuttle这个词，连续读错，为此课文重复了太多遍，今天整体用时也非常长，将近2个小时，需要注意。
