Question

7. The "eat-up" campaign,    by Xu Zhijun and his three friends ， has raised awareness of food waste all over the country.

A. started       B. starting

C. to be started    D. to start

Answer 1

7.    A考查非谓语动词。本句中的动词start与句子主语the "eat-up" campaign构成逻辑上的被动关系，故使用过去分词短语在句中作定语。其可以改写成一个定语从句which was started by Xu Zhijun and his three friends。 句意：由徐志军和他的三个朋友发起的"光盘"行动已经提高了仝国（人民）对于食品浪费的意识。故选A。
