题目内容
4.Don't put off today's work to tomorrow.You must do your homework today(改为被动语态)Don't put off today's work to tomorrow.Your homework mustbedonetoday.
分析 不要把今天的工作推到明天.你必须今天做你的作业.
不要把今天的工作推到明天.作业必须今天做.
解答 答案:be done.主语是your homework是动词do的承受者,故构成被动关系,句中有must,所以采用含有情态动词的被动语态结构:情态动词+be+动词的过去分词,动词do 的过去分词是done,所以答案为:be done.
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.
