1 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 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 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 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 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
6 题不明,换了我我会选B he'll give
7 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 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
