Scarcely had she put down the receiver —— the telephone rang again 答案选的when但是为什么不能选

问题描述:

Scarcely had she put down the receiver —— the telephone rang again 答案选的when但是为什么不能选
then?

解析:可以说这是固定搭配
had scarcely / hardly...when...或had no sooner...than...一.就.
只不过是句中把scarcely 提前,构成倒装结构
翻译:她刚一把接到的物品放下,电话就又打来了.哪里用的倒装结构啊?是因为scarcely的原因么?对呀,因为把scarcely提前了,它是属于否定的含义,所以用倒装结构了,正常的句子是 She had scarcely put down the....., 至于为什么用倒装,应该说是一种固定结构,习惯成自然,约定成俗的了。
