题目内容
Flying kites, ______ some researchers point out, can not only bring about joy to us, but also promote our physical and mental health.
| A．which | B．what | C．as | D．where |
C
解析试题分析：句意：正如一些研究人员指出的，放风筝不仅能给我们带来快乐，而且也能促进我们的身心健康。这里使用的是as引导的非限制性定语从句， as指代主句的内容，而且在定语从句中as做宾语，which引导非限制性定语从句只能放在句末，what不能引导定语从句，where在定语从句中不能做宾语，所以选C。
考点：考查非限制性定语从句
