Question

13．应该经常给这些花浇水．These flowers should be watered often．．

Answer 1

分析 These flowers should be watered often．

解答 答案：These flowers should be watered often．这里的主语是这些花These flowers，是谓语浇水water的承受者，构成被动关系，再者这里是说应该should，故用情态动词的被动语态：情态动词+be+过去分词，经常用often放句末，故答案是These flowers should be watered often．

点评 找到主谓，判断时态语态再翻译，本题就是被动语态来表达
