Question

用所给单词的适当形式填空； 1.they (buy )a nice bay yesterday.

2.they say there (be) a new bride across the rier in two years.
3.I'll let you know as soon as he (get)back.
4.look at the clouds! I think it (rain)
要理由

Answer 1

1. bought(buy的过去式形式，因为句末的yesterday体现一般过去时）

 2. will be (in two years两年以后，体现一般将来时）

 3. gets（as soon as 引导的时间状语从句常套用“主将从现”）

 4. is going to rain(Look at the clouds!根据该迹象所推断的马上会发生的事情，使用be going to 结构表示将来）

Answer 2

bought，时间为过去式
will be，时间表将来
gets，时间状语从句用一般现在时，主句用将来时。
will rain，根据语境推测，这是下雨前的征兆。故使用将来时。
