例句:the centre was simultaneously looking to a time when leading researchers could also be artists, writers and poets, and vice versa. 如果把vice versa整体当作副词的话为什么前面加了and?这是并列什么?
下面一题是选A还是B?为什么?
When children first learn to talk, there are some sounds that they find _______ to articulate.
A. difficult B. it difficult
如果选B,it是形式宾语吧!所以本题的实质是该不该用形式宾语,对不对?谢谢老师解析...
