2．right from the start there was trouble with the hubble. 从最开始哈勃望远镜就有问题。
（1）start为名词，表⽰"开始"、"开端"，from the start表⽰"从开始时"，副词right起强调作⽤：he didn't want to work at the firm(right) from the start.他从最开始就不想在这家公司上班。

（3）the hubble代指 the hubble telescope。

3．nasa is now going to put the telescope right…国家航天局准备纠正这⼀错误……put right表⽰"修好（故障等）"、"校正"、"纠正"等：have you put the watch/clock right?你把表/钟对好了吗？remember to put the lights right tomorrow.明天记得把灯修好。
Lesson 61 Trouble with the Hubble一、阅读课文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 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.
