Nothing would satisfy that boy but that I place him on my lap. 老师,这里的情态助动词用了would是什么目的?能改用will吗?两者有什么区别吗?
再如,It couldn't be better这样的句子中couldn't能改为can't 吗?请老师解惑,谢谢。
补充一下:It couldn't be better.和第一个句子完全是两回事,不存在虚拟的问题。
在can和could+否定词 +形容词和副词比较级的结构中,它们是可以互用的。
I can't agree with you more.
我再同意你不过了。(或:我完全同意你的意见。) The weather couldn't be worse.
天气再糟糕不过了。 He couldn't have done better.
他做得再好不过了。
