Question

【题目】The living standard of the people in China, _______ is shown in the report, has improved over the past decades.

A． what B． which C． as D． who

Answer 1

【答案】C

【解析】考查非限制性定语从句。句意：中国人的生活水平，正如报告里显示的那样，在过去的几十年里有了很大的改善。as引导非限制性定语从句，可放在句首、句中或句尾，而which只能放在主句之后；as常用于被动语态，意为“正如”，最常见的是as is known to us all，故选C。
