  ④下午2点你到老师办公室。

  You are_to_get to our teacher's office at 2 o'clock.

  (2)(重庆高考)James has just arrived, but I didn't know he ________ until yesterday.

  A.will come       B.was coming

  C.had come D.came

  解析:选B。考查时态。前一句说James已经到了,然后用but语意一转说直到昨天才知道他要来,据此可知应该填表示将来含义的时态。A项虽然表示将来,但是因为主句用了过去时,从句不能用一般将来时,因此只能选择B项,用过去进行时表将来。

  (3)(北京高考)-Hi, let's go skating.

  -Sorry, I'm busy right now. I________ in an application form for a new job.

  A.fill B.have filled

  C.am filling D.will fill

  解析:选C。考查时态。句意:"嗨,我们去滑冰吧。""对不起,我现在很忙。我正在填一份新工作的申请表。"由答句中的时间状语right now和上下文语境可知,此处表示正在发生的事,应用现在进行时,故选C项。

  (4)(大纲卷)Unless some extra money ________, the theatre will close.

  A.was found B.finds

  C.is found D.found

  解析:选C。考查动词时态和语态。句意:除非找些额外的资金,否则这个剧院就要倒闭。状语从句遵循"主将从现"的原则,同时money与find之间是动宾关系,故选C。

  2.助动词have的用法

用法 例句 have/had +过去分词,构成完成时态 By the end of last month, they had finished half of their work. have +been +现在分词,构成现在完成进行时 I have been studying English for ten years. have + been +过去分词,构成完成时态的被动语态 English has been taught in China for many years.   [即时演练3]
