英语句型问题
When they were trying to put out the fire,two firemen lost their lives.
已知本句可以省略they were
请问下面这个句子
When they go there,they will found a plane.
此句中可否省略they
原因何在
另外,第一个句子中代词they用在了所指代的two firemen前,这是英语中的习惯吗?
1.这是一个when引导的时间状语从句,在时间、条件状语从句中,当主句和从句的主语相同或者指代同一事物,且从句中有be动词时,可以省略从句的主语和be动词.
所以When trying to put out the fire,two firemen lost their lives.成立
2.When they go there,they will found a plane.
这个句子你给出来的时候有误,will是将来时,found如果作“发现”讲的话,就是find的过去式,我猜测你想表达的是：When they go there,they will find a plane.当他们去那儿时,他们将会发现一架飞机
这里的时间状语从句里可以省略they,转化成when going there,they will find a plane.
当没有be动词时可转化为动名词或者过去分词的复合结构,但是一定要保证前后主语一致,不能有逻辑错误.
当从句谓语主动时转化为动名词结构,主句谓语被动时转化为过去分词结构.
3.第一个句子中代词they用在了所指代的two firemen前,准确的地讲这不是习惯不习惯的问题
When引导的是一个时间状语从句,只是从句
我们可以这么理解,当你和别人说two firemen lost their lives,这是这是主句,是说话人真正要表达的意思,两个消防员失去了生命
那么听话人会紧跟着问一句“when?"什么时候?
那么说话在补充：When they were trying to put out the fire
我是用这样的方法讲解给我的学生听的,
