标题: 英语时态二
11.4 一般将来时



1) shall用于第一人称,常被will 所代替。

  will 在陈述句中用于各人称,在争求意见时常用于第二人称。

  Which paragraph shall I read first.

  Will you be at home at seven this evening?



2) be going to +不定式,表示将来。

  a. 主语的意图,即将做某事。

   What are you going to do tomorrow?

  b. 计划,安排要发生的事。

   The play is going to be produced next month。

  c. 有迹象要发生的事

   Look at the dark clouds, there is going to be a storm.



3)  be +不定式表将来,按计划或正式安排将发生的事。

   We are to discuss the report next Saturday.



4) be about to +不定式,意为马上做某事。

  He is about to leave for Beijing.

  注意:be about to 不能与tomorrow, next week 等表示明确将来时的时间状语连用。


11.18 现在进行时



 现在进行时的基本用法:

 a. 表示现在( 指说话人说话时) 正在发生的事情。

   We are waiting for you.

 b. 习惯进行:表示长期的或重复性的动作,说话时动作未必正在进行。

   Mr. Green is writing another novel. 

   (说话时并未在写,只处于写作的状态。)

   She is learning piano under Mr. Smith.

 c. 表示渐变的动词有:get, grow, become, turn, run, go, begin等。

   The leaves are turning red.

   It's getting warmer and warmer.

 d. 与always, constantly, forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。

   You are always changing your mind.



典型例题

  My dictionary ___, I have looked for it everywhere but still___ it. 

 A. has lost, don't find   B. is missing, don't find C. has lost, haven't found  D. is missing, haven't found.  

  答案D. 前句是一个仍在持续的状态,应用进行时,由于没有找到,其影响仍然存在,应用完成时,瞬间动词用于否定式时可用于完成时。
