◆ 一般将来时基本概念

  一般将来时表示将来某一时刻的动作或状态,或将来某一段时间内经常的动作或状态。由助动词shall或will加动词原形构成,shall 用于第一人称,will用于第二、三人称。在口语中,常用shall, will的缩写形式为'll , 如:I'll, you'll等。Shall not的缩写式为: shan't, will not 的缩写式为:won't.

肯定句:I/We shall/will go. You/He/She/They Will go.

否定句:I/We shall/will not go. You/He/She/They Will not go. 疑问句:Shall I/we go? Will you/he/she/they go?

◆一般将来时常与一些表示将来的时间状语连用,如: tomorrow(明天), next week(下周), from now on(从现在开始);in the future(将来)等。 其时间状语有如下几种 (1) this引导的短语 如 this year (2) tomorrow及其相关短语如tomorrow morning (3) next引导的短语 如 next month (4) from now on in the future in an hour 等。

◆一般将来时四种用法

(1)Will/Shall+ 动词原形 表示将要发生的动作或情况。

a. I will (shall) arrive tomorrow. b. Will you be free tonight? c. We won't (shan't) be busy this evening.

在以第一人称I或we作主语的问句中,一般使用助动词shall,这时或是征求对方的意见(a),或是询问一个情况(b):

a. Where shall we meet? 我们在哪儿碰头? b. Shall we have any classes tomorrow? 明天我们有课吗?

在这类问句中,近年来也有不少人用will。例如: How will I get there? 我怎么去?

(2)be going to+动词原形

①表示打算、准备做的事。例如: a. How are you going to spend your holidays?假期你准备怎样过?

②表示即将发生或肯定要发生的事。例如: a. I think it is going to snow. b. There's going to be a lot of trouble about this.

③"will"句型与"be going to"句型区别。前者表示纯粹将来,后者表示打算、计划、准备做的事情,更强调主语的主观意愿。例如: a. Tomorrow will be Saturday. b. We are going to visit Paris this summer.

(3)用现在进行时表示。

表示位置转移的动词(如:go, come, leave, start, come, go, arrive, reach等),可用现在进行时态表示按计划安排即将发生的动作。如: a. Uncle Wang is coming. 王叔叔就要来了。 b. They're leaving for Beijing. 他们即将前往北京。

(4)"be to+动词原形"和 "be about to+动词原形"表示将来。

①"be to+动词原形"表示按计划要发生的事或征求对方意见。例如:

a. Are we to go on with this work? 我们继续做吗? b. He is to visit Japan next year. 明年他将访问日本。

②"be about to+动词原形"表示即将发生的动作,意为:很快,马上。 We are about to leave.我们马上就走。
