改错——从句
Usually it is only much later which you realize you have spent far too much time there.
答案是把WHICH改成THAT,为什么不能改成WHEN?

强调句型.强调句强调的是it is 和 that 中间的东西,这里就是强调only much later ,很久以后,太晚了.
强调句要强调的其实是一个完整句子中的一个部分.你看这个句子去掉it is that 的时候句子是完整的.you realize you have spent far too much time theremuch later （那个only别去考虑了）.这是强调句一个最大的特点.所以当它出了一个空给你,你看看去掉it is that的成分是不是一个完整的句子,是完整句子的话,那就是强调句没错了.放心大胆的选上that好了.

强调句啊~

it is...that/who...为强调句型，只用that/who
要多思考，祝你英语进步！

因为是强调句子,必须用that,在这里强调的是状语only much later
