【问】 They treated him____a king when he won all the money.

A. as B. as being C. like D. like he was(Nelson，300 D)

正确答案为A。但是我在CGEL(§16. 47)中却遇到过这样的例句：

Her parents treated her {as if she were a baby. as/like a small child.

这不是意味着C(like)也是正确答案吗?

【答】 R. Quirk等人在CGEL中所提出的treat A like B这个句型，在目前只能看作是非正式用法，而不应看作是正式用法。因此，目前除CGEL外，还没有一部辞书将treat A like B作为正式用法而收录。

2. They treated him as a thief. (Hill)

3. My employer treated my request as a joke. (LDCE)
