题目内容
6．-The TV says it is going to rain tomorrow．-If it tomorrow，everybody will be happy．We have had a long difficult time having no rain．（ ）
| A． | rain | B． | rains | C． | rained | D． | will rain |
分析 --电视上预报明天要下雨了．
--如果明天下雨的话，每个人都会很开心．我们已经度过了一段很长和艰难的没有雨水的时光．
解答 答案：B
本句考查if引导的条件状语从句，在含有条件状语从句中的复合句中，如果主句中用一般将来时，从句使用一般现在时表将来，一般现在时的构成是：主语+动词原形/动词的第三人称单数形式；且从句中主语it 是第三人称单数形式，再根据句意"如果明天下雨的话，每个人都会很开心．"，应该选 rains．故选B．
点评 if引导的条件状语从句是中考的热点，注意时态遵循"主将从现"的原则，即：在主句是一般将来时的情况下，从句用一般现在时表将来．
