【題目】People ___________of serious pollution，so they began to take action to protect the environment.

A.warnedB.are warnedC.has been warnedD.were warned

【答案】D

【解析】

句意：人們被警告嚴重的污染，所以他們開始采取行動保護環(huán)境。

考查時態(tài)和語態(tài)。warned一般過去時的主動形式；are warned一般現(xiàn)在時的被動形式；has been warned現(xiàn)在完成時的被動形式；were warned一般過去時的被動形式。根據(jù)began此處用一般過去時，此處主語people與謂語warn之間是被動關(guān)系，因此用一般過去時的被動形式，故選D。
