状语从句是英语语法中的一种从句,用来修饰主句中的动词、形容词或副词。当状语从句的主语和主句的主语一致时,可以使句子更加简洁明了,表达更加精准。
例如,看下面两个句子:
- As she was tired, she went to bed early.
- Tired, she went to bed early.
第一个句子中,状语从句“As she was tired”中的主语“she”和主句中的主语“she”重复,造成了重复和冗余。而第二个句子中,直接用“Tired”作为状语,把状语从句省略了,使句子更加简洁明了。
再比如:
- Because she was late, she missed the train.
- Late, she missed the train.
第一个句子中,“Because she was late”是一个状语从句,主语是“she”,而主句中的主语也是“she”,造成了重复和冗余。而第二个句子中,把状语从句省略掉了,直接用“Late”作为状语,使得句子更加简洁明了。
总之,当状语从句的主语和主句的主语一致时,可以省略状语从句,直接用状语作为主句的修饰语,使得句子更加简洁明了,表达更加精准。
