英语语法之状语从句的省略

英语语法之状语从句的省略

英语语法之状语从句的省略2018英语语法之状语从句的省略 状语从句的省略是英语语⾔在使⽤过程中出现的⼀种较普遍的语法现象,⼀⽅⾯,它能使句⼦变得更简洁,但另⼀⽅⾯,它对你的理解能⼒提出了很⾼的要求,增加了理解的难度。

我们知道状语从句的引导词可以帮助⼤家判断前后两句话的逻辑关系,⼀旦省略了引导词,那么弄清楚前后两句话的逻辑关系就⽐较难,这就需要⼤家掌握状语从句的省略原则,在此基础之上再进⼀步分析前后的逻辑关系,从⽽把⾥⾯的逻辑关系翻译出来。

当主句的主语与从句的主语⼀致时,可以省略从句的主语,连接词可以保留,从句中的谓语动词与主语是主动的关系就⽤动词的ing形式,如果是被动的关系就⽤ed形式。

⽐如说2011年英语⼆翻译的⼀个句⼦:While producing large quantities of CO2, these computers emit a great deal of heat, so the centers need to be well air-conditioned。

这句话中while后⾯的句⼦省略了主语,因为从句中的主语和后⾯的主语⼀致都是these computers,并且动词produce与主语是主动的关系,所以变成分词形式producing。

这句话翻译为:这些计算机在产⽣⼤量⼆氧化碳的同时,还释放了⼤量的热量,因此数据中⼼需要良好的空调设备。

当主句的主语与从句的主语不⼀致时,要保留从句的'主语,连接词必须省略,从句中的谓语动词与主语是主动的关系就⽤动词的ing形式,如果是被动的关系就⽤ed形式。

⽐如说1999年英语⼀阅读中的这句话:But, for a small group of students, professional training might be the right way to go since well developed skills, all other factors being equal, can be difference between having a job or not. 这句话的状语是all other factors being equal,省略了连词because,因为主句的主语与从句的主语不⼀致,所以保留了all other factors。

例子:原句:When he was young, he often went fishing with his father.省略:When young, he often went fishing with his father.2. 当从句和主句使用相同的状语时,可以省略从句中的状语和连词。

例子:原句:After she finished her homework, she went to bed.省略:After finishing her homework, she went to bed.3. 当从句中的主语与主句的主语一致,并且是代词时,可以省略从句中的主语和连词。

例子:原句:Before he left, he said goodbye to his friends.省略:Before leaving, he said goodbye to his friends.二、状语从句的重复在使用状语从句时,为了加强语气,突出特定信息,或更好地表达意思,我们也可进行状语从句的重复,以便更加明确强调主要内容。

1. 在表示条件的状语从句中,可以进行重复以加强条件的语气。

例子:原句:If you work hard, you will succeed.重复:If you work hard, if you really put in the effort, you will succeed.2. 在表示原因的状语从句中,可以进行重复以突出原因的重要性。

一.时间状语从句的省略。这类从句主要由when, while,as soon as,once,until等引导。例如:
1. When (he was) still a boy of ten, he started working to support himself.

但若if引导的是表示假设的虚拟条件句,虽具备条件, 可不能用于这类省略。这时如果if从句的谓语动词中含有were, had,should,则可以用倒装省略,即将were,had或should提 到句首,而将连词if省略。 例如:
Were it not for you, I would also go there with them. Had you come here earlier, you would have met him. Should it be fine tomorrow, we would go for an outing.
