Yes,I can./No,I cant.是的,我会。/不,我不会。 can与第二人称连用,常用于熟人之间表示邀请或 请求,即Can you.?,接受请求或邀请时,常用Sure,Id love to./OK,that sounds great./Certainly./Of course等回答。 拒绝邀请,一般不直接说No,而应说(Im)Sorry,I cant.以示礼貌,然后说明理由;也可用Id love/like to,but.委婉地说明不能接受的原因并表示歉意。 【注意】发出邀请或请求时,也常用could使语气更委婉、客气。 【拓展】can还可以表示推测,常用于否定句。 eg:That man cant be Mr. Liu because he is in London now.那个男人不可能是刘先生,因为他现在在伦敦。,一、单项选择。 1David,_ you please sweep the floor and take out the trash?
