Question

Zhengzhou was attacked by such a terrible sandstorm ________ few residents had ever experienced before.

A．which

B．a(chǎn)s

C．where

D．that

Answer 1

B

試題分析:考查as 引導(dǎo)的定語從句。句意：鄭州遭遇了如此可怕的沙塵暴，這樣的沙塵暴是很少居民以前曾經(jīng)歷過的。此題很容易錯選成D 選項(xiàng)，認(rèn)為是such …that 句型，但是在such…that 中that從句應(yīng)該句子完整不少成分，但此句中experienced 缺少賓語。所以判斷為定語從句，因先行詞sandstorm 前有such 修飾，所以定語從句應(yīng)由as 引導(dǎo)，故B為正確選項(xiàng)。
