考试中常见的考点有:要学生区别是条件、时间状语从句还是宾语从句,因在宾语从句中该用什么时态用什么时态,如: I want to know if he will come here tomorrow? 在宾语从句中的条件状语从句与主句的关系,如: I want to know if it rains he will come here tomorrow??
在原因状语从句中主要是① because, 应译为因为。它表达的因果关系最强,如: He didn't pass the exam because he didn't study hard? ② since 应译为既然,如: Since you were ill yesterday? I left some notes on your desk? ③ as 应译为由于,如: As it is too hot we'd better go swimming? since 与 as 所表达的因果关系远比 because 弱得多。
而 for 表达的因果关系最弱。它不能用于句首,如: He studies hard, for he wants to go to college??在比较状语从句中有同级比较 as as, 如: This book is as good as that one? 要注意的有两点:① as as 中间要用原级而不是比较级。② 用形容词还是副词,如: Mary writes as carefully as Tom? 而其否定句为 not as (so) as, 如: They didn't work so hard as we did, 而不同级比较用比较级加 than, 如: He is younger than I am? 要注意的是表示越来越这一概念时有两个句型:① 比较级+and+比较级,如: The days are getting longer and longer? The little girl is becoming more and more beautiful? ② 定冠词 the + 比较级+ the + 比较级,如: The harder you study, the more you can learn??方式状语中要注意的是as (连词)与 like (介词)的区别。 as 作为连词其后接从句,如: Please do it as I did it? 但后面的句子常作省略,如: Please do it as I? 而 like 是介词,其后要接的是宾语,如: Please do it like me??
