题目内容
20.这里不让吸烟 Everyoneisn't allowed to smoke here.分析 isn't allowed.
解答 答案:isn't allowed.结合句意这里是表达客观事实用一般现在时,表示允许做某事结合后面的to do sth用allow sb to do sth,主语Everyone是allow的承受者,构成被动关系,故用一般现在时的被动语态sb be allowed to do sth,主语是不定代词,故用单数is,加上not表示否定,故答案是isn't allowed.
点评 allow sb to do sth意思是"允许某人做某事";
allow sb sth"给与,提供某人某物".如:
She allowed us to smoke.
她允许我们抽烟.
Their teacher allowed them three days for the assignment.
他们的老师给他们三天时间完成作业.
