when I ran out to find that a big tree had fallen down 最前面的when为什么要去掉

问题描述:

when I ran out to find that a big tree had fallen down 最前面的when为什么要去掉

这个句子应该是to+动词原形引导的意料之外的结果状语从句,而不是由when引导的时间状语从句

我认为不去掉也可以,但是要写成:when i ran out ,a big tree had fallen down.

有了when句子就变成“当我跑出发现一棵大树已经倒下”,句子就很不通顺。少了when句子就变成“我跑出来发现一棵大树已经倒下”,句子就通顺很多了!

句子太长,用when多余

when后面要加时间状语,这里并没有提到,去掉后意为:我跑出去发现大树倒了
如果一定要加when可改为:When I ran out,I found out that a big tree had fallen dawn 意为:当我跑出去的时候,我发现大树倒了
