3.含有情态动词的主动句与被动句之间的转换含有情态动词的主动句变为被动句时,要把主动句中的宾语变为被动句中的主语;主动句中的谓语变为“情态动词+be+及物动词的过去分词”;主动句中的主语变为介词by的宾语(如果不强调动作的执行者,by短语常可省略)。主动句：She must clean her rm every day. 主语 谓语 宾语被动句：Her rm must be cleaned (by her)every day. 她必须每天打扫她的房间。

解析:我们可用“语法分析法”解答本题。主语 trees 与动词 plant 存在被动关系,故应用被动语态;含有情态动词的被动语态的结构为“情态动词+be+及物动词的过去分词”,故选 B。 答案:B
二 被动语态结构小结各种时态的被动语态形式归纳(以动词give为例):
(2019·广东) 中考·链接 It is said that ne Greater Bay Area university in Guangdng in the future.A. will be built B. build C. will build D. is built
解析: 我们可用“语法分析法”解答本题。结合选项可知，主语ne Greater Bay Area university(一所大湾区大学)与谓语动词 build(建设)是被动关系,应用被动语态;由时间状语 in the future 可知,要用一般将来时的被动语态,其构成为“will + be +及物动词的过去分词”,故选 A。句意:据说将来会在广东建一所(粤港澳)大湾区大学。答案:A
三.情态动词表推测1.情态动词表推测时,不同的形式表示不同的时态。
2.情态动词表推测的意义和用法

注意 ① culd 用于否定句时,语气较 can’t缓和意为“不可能”The news culdn't be true那个消息不可能是真的。
② may/might用于否定句时，表示不太有把握的否定推测，意为“可能不”。There may nt be enugh mney t pay fr the car.可能没有足够的钱来买小汽车。The news might nt be true.那个消息可能不是真的。
