25、tball.你不能玩篮球。Can you.?“请你好吗?”表示说话人的请求;Can I.?“我可以吗?”用来征求对方是否允许自己做某事。如在句末加上 please一词就显得更有礼貌了。例如:Can you help me,please?请你帮助我好吗?3.表示可能。例如:He can be at home now.他现在可能在家。,二、can的句式变化如下:在变否定句时,直接在我后加上“not”,可缩写成cant或cannot,但不能写成cannt。例如:He can swim.He cant swim.2.在变一般疑问句时,把can直接移到主语前(原主语的首字母改成小写,第一人称应变为第二人

29、语用:Yes,主语+must.或 No,主语+neednt.neednt 表示“不必”,即没有这个必要。如:Must I go home now?我现在必须回家吗?Yes,you must.是的,你必须回家。(No,you neednt.不,你不必。)d.must 还可以表示肯定的、较为有把握的推测,意为“一定;肯定”等。如:The door is open.He must be at home.门开着,他一定在家。,特殊疑问句:以特殊疑问词(what,where,who,which,when,whose,why,how等)开头引导的句子。此类句子应该问什么就答什么,不能用“yes、no”来回
