答案：

1.选C,by the end of this year, 是明确表示将来的时间状语,主句表示在这个将来时间以前完

成的动作,故应用将来完成时.

2.选D.by next summer是明确表示将来的时间状语, 主句表示在这个将来时间以前完成的动作,故应用将来完成时.

3.选D,by the time 引出的是时间状语分句,分句中用的come用一般现在时,表示将来概念,相当于一个表示将来的时间状语,主句谓语动词表示在将来某一时刻以前必定完成的行为,应该用将来完成时.不能选A,句子中带有表示将来时间的状语分句,故应该用与将来时相关的时态.也不能选C ,improve 在该句中作”好转”,”变得更好”解,为不及物动词,所以用被动语态时错误的.

14 ．B hardlywhen( 一 就 ) ， hardly 后应当用过去完成时， when 后面用一般过去时。 hardly 的特殊用法，在其后面跟倒装语序，所以选 B 。

15 ． A过去将来时态。 Forgive 原谅， She’d 相当于： she would. 妈妈不知道我看电视花费了多长时间，如果她知道的话，我相信她将永远不会原谅我。

16． D过去完成时态。 发现错误这个动作发生在纠正数据那个动作之前，而改正数据的动作用的是过去时态，所以，发生在过去的过去的动作就用过去完成时态。 error 错误。 correction 改正，是名词。 data 数据。
