将来完成时与将来进行时与一般将来时区别

将来完成时

1) 构成will / shall + have + p.p.

2) 概念

a. 状态完成：表示某事继续到将来某一时为止一直有的状态。

b. 动作完成：表示将来某一时或另一个将来的动作之前，已经完成

的动作或已获得的经验。

将来完成时用来表示在将来某一时间以前已经完成或一直持续的动作。经常与before+将来时间或by+将来时间连用，也可与before或by the time引导的现在时的从句连用。如：

He will have gained his pilot's license before his next birthday . 他下个生日前会拿到飞行证的。

You will have received an invitation to the wedding as well . 你肯定会收到参加婚宴的邀请的。

They will have been married for 20 years by then.

You will have reached Shanghai by this time tomorrow.

将来进行时

1) 概念：表示将来某时进行的状态或动作，或按预测将来会发生的事情。

She'll be coming soon.

I'll be meeting him sometime in the future. 注意：将来进行时不用于表示"意志"，不能说 I'll be having a talk with her.

2）常用的时间状语

Soon, tomorrow, this evening，on Sunday, by this time，tomorrow, in two days, tomorrow evening

By this time tomorrow, I'll be lying on the beach.

时态1 一般将来时

概念 表在将来某个时间会发生的动作或情况。常和tomorrow, next year, in 2008等表示将来的时间状语连用，其表现形式多达5种。

构成 will/shall + do, be to do, be about to do, be going to do,

例句 They will arrive at the small village tomorrow.

I am going to do my homework this evening.

He is to fail

备注 1. 一般将来时总是用在一些时间状语从句或条件状语从句的主句中：

We will begin our class as soon as the teacher comes.（主句用一般将来时，从句中一定要用一般现在时替代一般将来时。）

2. 某些移动性动词或趋向动词如leave, start, go ,arrive, come, stay，finish等用进行时可表示将来意义。如：

I am just finishing my work, and it won’t take long.

I am leaving for Beijing tomorrow.

3. “祈使句 + and/or + 句子”，这种结构中and后面的句子谓语用一般将来时，由于祈使句具有假设条件意义，后一分句在这一条件下要产生的结果，所以要用将来时。如：

Let’s keep to the point or we will never reach any decisions.

Use your head and you will find a way.

4. “am (is, are) going to + 动词原形”，表示已经决定或安排要做的事或表示有某迹象表明必然或很可能发生的事情，“am (is, are) about to + 动词原形”表示按照预定计划或打算准备着手进行的动作，但be about to do不可与段时间状语连用。“am (is, are) to + 动词原形”表示必须、必然或计划将要做的事，或注定要发生的事情，而“will + 动词原形”而后者表示“临时决定去做某事”。如：
