1、一般将来时的六种表示法一、will/shallwill/shall 通常用来表示将来时间。 Will 用于第一、二、三人称主语，shall 用于第一人称主语，都可以表示将来时，但是这种意义通常夹杂着情态意义，即带有说话人的主观态度和看法，比如表示“预见”：You will feel better if you after taking this medicine.He wont be here in time unless he comes by air.We shall know the result next week.I am sure that I shall not lose my

Im going to be late.Look at that black cloudsthere is going to be a storm.表“意图”的用法有时候可以与“will+do”互换使用，但是也要注意区分。 Be going to do表示的是说话之前就已经决定了，而“will+do”则是说话时临时想到的。A: What a terrible box!B: I will help you to carry it.(这里不能换为 am going to)

8、常见于条件状语或时间状语从句中。If he comes, I will let you know.Ill give it to you after I finish it.Will 表意愿、意志的时候也可以放在条件状语从句中。如：If you will listen to me, Ill be able to help you.I will tell you if you will not tell anyone.在主语中用一般现在时表示将来时间通常是表示有标记的极其明确的将来或描述的不能更改的将来事件或预定活动，如时间表、日程表、形式里所规定的将来活动。Tomorrow is Saturda
9、y. The summer holiday starts on June 28.The plane takes off at 20:30 tonight.注意：表示将来时间，一般现在时和现在进行时都有表示位移的动词连用，而且都有计划、安排的含义。但是现在时所暗含的计划比较客观，因而具有不可变更性，而且用现在时表示将来在口气上也比较正式。Im leaving tomorrow.（个人的主观意愿）The plane takes off at 20:30 tonight.（时间表上的规定）六、be about to即将发生的动作，指眼皮底下就要发生的事情，一般是不跟时间状语的。Look, the train is about to leave!
