Question

20．雨正下得如此大所以他不得不待在家里．（so…that）It is raining so heavily that he has to stay at home．

Answer 1

分析 It is raining so heavily that he has to stay at home．

解答 答案：It is raining so heavily that he has to stay at home．
这里是说客观事实用一般现在时，表示如此…以至于…用so/such…that，主句是It is raining正在下雨，用副词heavily修饰rain表示雨大，that引导的结果状语从句，主语是he，表示不得不have to后加动词原形，主语是三单，故has to，待在家里stay at home，故答案是It is raining so heavily that he has to stay at home．

点评 such…that作"如此…以致"解，连接一个表示结果的状语从句．与so…that 意思相同，但用法不同．如：so…that这一结构中，so后边可加形容词或副词，而such后边要用名词（这个名词前面可以带形容词，也可以不带）．
