答案
1 c 题因有tomorrow故用将来时；因有this time，说明是时间点，故用进行时，加起来就是将来进行时
2 d 题因有tomorrow故用将来时；by this time是“到了这个时候”，故用完成时（by this time本身就是完成时的时间状语）
3 b 题因有tomorrow故用将来时；machinery不可数故用单数；arrive是非延续性动词（又称瞬间性动词），非延续性动词的进行时本身就表示将来时的意义，故不再用将来时的助动词
4 c 题真实性条件状语从句要遵循“主将从现”的原则，即主句用将来时从句用现在时；而第二句根据语境可分析出说的是一般情况，故用一般现在时
5 d 题by the end of 和by this time相同，为完成时的时间状语；而this term根据语境可分析出是还未到，即用将来时，所以为将来完成时
6b 题不明，换了我我会选he'll give
7 c 题因有by the time故确定用完成时；而完成进行时一般强调一段时间内一直在做某事，且句中没有完成进行时的时间状语，只有for即普通完成时
8 a 题因从句中用is going故主句中不用过去时；be to do比be going to do计划性更强也更正式故选择前者
1.I haven\'t heard from him_since_he went to America.
2.He won\'t be here_unless_he is invited.
3.He will not go to the cinema_because_he is very busy.
4.We found the key_where_she had left it.
5.We found the books two days_before_he had gone away.
6.We had no sooner got to the station_than_the train left.
7.He is explaining clearly_so that_they could understand.
8.Do not leave the room_until_yor have finished the test.
9.she sang_when_she went along.
