He asked me to open the window. He sai
2、d,“Dont do that again.” He told me not to do that again. 以 Let 开头的祈使句变为间接引语时，有下列几种形式： 1)Lets 如果表示某种建议，变间接引语时，要用“suggest+动名词”或“suggest+宾语从句”结构( 从句谓语用should+动词原形)。例如： Our teacher said,“Lets go boating together.” Our teacher suggested going boating together. Our teacher suggested that we (should) go bo
3、ating together. 2)Let 祈使句作“允许、同意”解，变间接引语时，可按一般祈使句变间接引语的规律进行。例如： “Let her come with me, mother. Ill take good care of her.”said Tom. Tom asked his mother to let her go with him and promised to take good care of her. 2) Let him(或 them)表示“建议”时，其间接引语用应 suggest + 动名词复合结构或 suggest(或 say)+宾语从句( 从句谓语用should
4、 + 动词原形)。 Mother said,“Let him go to school.” Mother suggested his going to school. Mother suggested that he (should) go to school. 4)Lets not 单独用来回答一个肯定的建议时，其间接引语一般使用 be against或oppose the idea 等短语。例如： “Lets sell the old car and buy a new one,”said Peter. “Lets not,”said Mary. Peter suggested selling the old car and buying a new one,but Mary was against it.
