问题详情:
________ is often the case with children, Tom was better by the time the doctor arrived.
A.It B.That C.What D.As
【回答】
D
【详解】
考查定语从句。句意:汤姆在医生赶到前已经完全没事了,这种事经常发生在孩子身上。as 引导非限制定语从句,先行词是整个句子,as在从句中作主语,意为“正如,像……一样”。故选D。
【点睛】
as可以引导非限制*定语从句,可以放在句首或句末,意为“正如”,指代主句的内容,在从句中可做主语,宾语和表语。有些固定搭配可记忆,如:as is often the case;as is know to all等。
知识点:非限制*定语从句
