题目内容
【题目】The air quality in the city, ______ is shown in the report, has improved over the past two months.
A. that B. it C. as D. what
【答案】C
【解析】句意:正如报道的那样,在过去的两个月里这个城市的空气质量已经改善了许多。本句的难点是as引导的非限制性定语从句将主句分割成了两部分,如果把句子转换成 is shown in the report, the air quality in the city has improved over the past two months. 就明了了。as指代主句整句内容,且在从句中作主语,意为“正如”,故选C。
