六、对现在完成进行时的考查
现在完成进行时是由“have / has been+现在分词”构成，表示从过去某一时刻发生的动作，一直延续到现在，并且还可能继续下去。它与现在完成时的区别如下：
1.现在完成时强调的是完成的动作，而现在完成进行时是持续了一段时间的动作，这个动作刚停止或 仍在继续。
I have written an article.（已完成） I have been writing an article. （还在写）
2.有些延续性动词，如live, teach, work, study, learn, stay等因现在完成时与现在完成进行时差别不大。
I have lived here for ten years. = I have been living here for ten years.另外注意的是：
表短暂动作的动词（finish, marry, get up, come, go等）一般不能用现在完成进行时。
Now that she is out of a job, Lucy ____going back to school, but she hasn’t decided yet.
A. had considered B. has been considering C. considered D. is going to consider
解析：该题是在交际情境中考查动词时态的用法。根据句意应选完成进行时，表示过去的动作（考虑返校学习）持续到现在（还没有决定）今后还有可能进行的动作。句意：既然露西失业了，她一直在考虑返校读书，但她还没有定下来。
七、对过去完成时态的考查
过去完成时，经常以“过去”为背景，要想表达比这一背景更早的动作，常用此时态。
— George and Lucy got married last week. Did you go to their wedding?—No, I ___. Did they have a big wedding?
A. was not invited B. have not been invited C. hadn’t been invited D. didn’t invite
解析：没有被邀请发生在George and Lucy举行婚礼之前，即过去的过去。
常见考点有：
①把过去完成时放在含有when, before, after, until, as soon as等引导的时间状语从句的复合句中考查。
When the old man ___ to walk back to his house, the sun ___ itself behind the mountain.
A. started; had already hidden B. had started; had already hidden C. had started; was hiding D. was starting; hid
解析：考查动词时态。主句的动作在前，从句的动作在后，从句中谓语动词 started to walk back表示过去时间点，因此主句的动作应用过去完成时。
②把过去完成时放在by + 时间点或by the time + 从句的句子里考查。
By the end of last year, another new gymnasium ___ in Beijing.
A. would be completed B. was being completed C. has been completed D. had been completed
解析：by the end of last year常与过去完成时连用，表示到过去某个时候前已经完成的动作。
