(一)一般将来时

一般将来时表示将来某个时间要发生的动作或者存在的状态。通常与表示将来的时间状语连用,如tomorrow, the day after tomorrow, next year, next month, next week, in 100 years等。

be going to do (动词原形)结构:表示打算、准备做的事情或者肯定要发生的事情。

1. 表示预见

Do you think it will rain?

you will feel better after a good rest.

2. 表示意图

(1)will+主语+do?? will sarah come to visit me next sunday?

(2)there be 结构的一般疑问句:will there + be ??

will there be fewer trees? yes, there will. / no, there won’t

否定句构成:will + not (won’t)+do
