Question

帮我看看新概念3的一个语法

This can give rise to curious situations, as it did in the case of Alfred Bloggs who worked as a dustman for the Ellesmere Corporation.中的as it did的did后面为什么没有宾语?还有in the case of 是不是相当于副词?

Answer 1

as it did中的did指代了前文中的give rise to curious situations.

作用相当于，回答一般疑问句时候的Yes, I do. 不是实际意义：做。所以不需要宾语。

in the case of 确实相当于副词，做状语。

因为介词短语一共只有三个功能。

1. 相当于副词，担任各种状语。e.g. I get up at 6:00.

2. 担任表语。e.g. I am at school.

3. 担任后置定语。 e.g. The boy under the tree is Tom.
