A．throw away	B．thrown away
C．be thrown away	D．been thrown away

答案

解析

试题分析：句意：废纸是禁止被扔掉的。我们应该保持环境卫生。分析：考查被动语态的用法，被动语态的构成: be + done（动词的过去分词）。分析：禁止被扔掉，体现情态动词的被动词态。构成为must be +done (动词的过去分词).同时考查固定短语：throw away扔掉。故选C

核心考点

试题【Waste paper mustn’t _______. We should keep our environment clean.A．throw awayB．】；主要考察你对动词的被动语态等知识点的理解。[详细]
