I got in touch with him immediately I received his letter. My sister came directly she got my message. Every time I catch a cold, I have pain in my back. △ 如果把no sooner, hardly, scarcely, barely置于句首，它所连带的这部分就要倒装，如： No sooner had she heard the news than she fainted. (She had no sooner heard the news than she fainted.) 2、地点状语从句 引导地点状语从句的连词有where, wherever (no matter where) 等，例如： Where I live there are plenty of trees. 我住的地方树很多。 Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。 Bamboo grows well where it is warm and wet. You may go wherever you like. 有时，- where构成的复合词也可以引导地点状语从句，如： Everywhere they went, they were kindly received / warmly welcomed. We’ll go anywhere the Party directs us. 3、原因状语从句 (1) 引导原因状语从句的连词有 because, since, as , now that (2)??because, since, as, for 用法比较： 一）. because: 语气最强，回答why时用because，所表示的是直接理由，因果关系不能同so连用。 Why are you late?
