(一)状语从句概括定义状语从句用作状语,是起副词作用的句子。
地点状语从句能够放在主句以前,也能够放在主句以后,时间、条件、原由和退步状语从句放在句首时需要用逗号和主句分开。
分类依据其作用能够分为时间、地址、原由、条件、目的、退步、方式和比较等状语从句。
作用它能够修饰谓语、非谓语动词、定语、状语和整个句子。
(二)状从句解1.状从句引用法when意“当⋯的候”。
When引从句的能够是延性,也能够是瞬。
而且when 有表示“就在那”while意“在⋯的候,在⋯ 的同”。
While 引从句的必是延性的,生,并主句和从句的作同生(或许相)。
While有能够表示比。
示例A liar is not believed when he speaks the truth.者真也没有人相信。
When he arrives , I’ll call you. When you laugh and smile, your body relaxes.While I was standing at the window, I saw several boys running along the street.While John was watching TV, his wife was cooking.as意“一⋯一⋯”。
As 引的作是延性的,生短,一般用于主句和从句作同生; as 也能够一前一后。
after意“在⋯以后”。
表示主句作生在从句作以后。
主句与从句的作关系与before 引的从句相反。
before意“在⋯以前”。
引的从句不用否认形式的,而且当 before 引的从句位于主句以后,有成“就,才”。
当主句用未来,从句是用在;假如 before 引的从句用的是去,主句多用去达成,以便体作的先后。
till意“直到”。
一般状况下能够和 until 互。
假如主句中的是瞬,必用否认形式;假如主句中的是The writer was angry as he was travelling on a train to London because someone had invaded his “space”.He smiled as he stood up.With many hungry visitors waiting, don’t stay too long at your table after you have finished.If an early exit is necessary, you can leave after a scene is over.You can’twatch TV beforeyou finish your homework. Before it ended, the theatre was almost empty.My father had left for Canada just before the letter arrived.She didn’t even know that it was an earthquake till she saw a shaking ( moving from side to side) light.The fireman worked very hard延性,用一定和否认形式都能够,但表达的意思不一样。
