题目内容
12.We should plant more trees every year,the more,the better.(改为被动语态)More trees shouldbe planted every year,the more,the better.
分析 我们应该每年种更多的树,越多越好.
每年都应该种更多的树,越多越好.
解答 答案:be planted.主语more trees是动词plant"种植"的承受者,构成被动关系,前面有情态动词should,故用情态动词的被动语态---情态动词+be+过去分词,plant的过去分词planted,故答案是be planted.
点评 此题要求把主动语态变为被动语态,做这类题时,首先由原句的谓语确定采用哪种被动语态结构,再看主语,二者结合即可得出答案.
