Question

18．他在电脑游戏上用了太多的时间，以至学习落在了同学的后面．
Hespends so much time on computer games that he doesn't catch up with his classmates in study．

Answer 1

分析 spends so much time on computer games that he doesn't．

解答 答案：spends so much time on computer games that he doesn't．结合句意表达的是客观事实用一般现在时，表示花时间做某事，结合主语he用spend+时间+on sth，故spends  much time on computer games，表示如此…以至于用so/such…that，修饰much，故用so，that引导的结果状语从句，主语he三单，catch是实意动词，故doesn't，故答案是spends so much time on computer games that he doesn't．

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）如果such后边的名词前由many、much、few、little等词所修饰的话，则不用 
such而用so．例如：
He had so many falls that he was black and blue all over．
他摔了很多跤，以致于全身上下青一块，紫一块的．
He had so little education that he was unfit for this job．
他所受教育很少，不适合做这个工作．
