Step4            Grammar:

                                          (A)  Talking about future:

 

1. The simple future tense

2. be to/ be about to

3. Present continuous tense

4. Simple present tense

 

Explaining the use of the grammar:

*         be going to do/ be   //   shall/ will do/ be

      •It is going to rain.

       •We are going to have a meeting today

       •When he comes, I will give him your message.

注意:

1)在有时间状语从句或条件状语从句的句子中,不能用be going to表示将来,而应该用shall    will表示。

2)前者表纯粹将来,表打算be going to表原来已经决定的动作考虑做某事,will表说话时   刻决定动作.

 

*         be to do,表示按计划要发生的事或征求对方意见。例如:

       •The boy is to go to school tomorrow.

       •Are we to go on with this work?

       •Audrey and Jimmy are to be married in June.

*         be about to do表示即将、马上发生的动作,后面一般不可以跟时间状语。

       Sit down everyone. The film is about to start.

 

*         does/do, be doing

       •The meeting begins at seven.

       •The train starts at nine in the morning.

       •He is coming to see you tomorrow.

分析:这二种时态表示将来,往往限于以下动词:go,come,start,begin,move,leave,arrive, stay,         等前者表示组织安排,后者表示个人计划安排,如:

       •School finishes on January 18.

       •Jane and Betty are going on separate holidays in a few days' time

 

*         The present continuous tense

       a. 表示现在( 指说话人说话时) 正在发生的事情。

     à 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。

          à Mr. Green is writing another novel. 

              (说话时并未在写,只处于写作的状态。)

     à She is learning piano under Mr. Smith.

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

     à The leaves are turning red.

     à It's getting warmer and warmer. 

       d. always, constantly, forever 往往带有说话人的主观色彩。

     à 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.  

 

(B) The future continuous tense

 

1)        表示在将来某一时间正在进行的动作

à I'll be taking my holiday soon.

à They will be meeting us at the station.

  在口语中代替will/shall do

à I hope you will be coming on time.

à I'll be seeing Mr. Smith tomorrow.

à The minister will be giving a speech on international affairs. (部长将就国际事务发表演讲.)

 

2)        将来进行时的特殊用法:    (表示原因、结果或猜测。)

   请你明天下午来吧。我明天上午有个会。   (表原因)

à Stop the child or he will be falling over.

   抓住那个孩子,要不他会掉下去的。   (表结果)

Ø         用在问句中,表示委婉礼貌。
