Question

【題目】Recently our community has launched a campaign among all the residents，________we are called upon to do our little bit to prevent the worsening environment.

A．which B．that

C．when D．where

Answer 1

【答案】D

【解析】定語(yǔ)從句。句意：最近我們社區(qū)在所有居民中發(fā)起了一項(xiàng)運(yùn)動(dòng)，運(yùn)動(dòng)號(hào)召我們做力所能及的事來(lái)阻止環(huán)境的日益惡化。分析句子結(jié)構(gòu)可知，空處引導(dǎo)非限制性定語(yǔ)從句，修飾先行詞a campaign，且從句中不缺成分，故選關(guān)系副詞where。
