will和will
先看一下新概念二61课课文：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.
我的问题是,△符号后面的will be后面的词为什么加ing 而☆后面的will grab 为什么不是ing形式而是原型?

will do是一般将来时态
will be doing 是将来进行时态,
这是两种不同的时态,从语法角度看两者可以互换,但是将来进行时态更加生动形象,表示在将来某段时间一直在做...
