问题描述：

NASA is now going to put the telescope right.NASA____it.A is repairing B has already repaired
C will be repairing D to repair ,选择正确答案,及分别说出每个答案为什么对与错

答

C 这是将来进行时态的表示。前一句已经表明是将来时态。所以后一句的NASA 的动作还没有做，要用将来时态

答

B B是现在完成时，说明已经修理好了
所以才有现在的正在把telescope put上去

答

选C will be repairing是将来进行时,正确
A is repairing是现在进行时,第一句明明说是将来是事情,故错误
B has already repaired是现在完成时,动作还未发生,怎么就完成了呢?错误
D to repair这是个非谓语动词,不能充当谓语,错误

答

put......right是“把……修好”。is now going to “正要修好”说明正在修，且还没修好，所以我觉得选A
