helpkidswithcomputer.can的用法

can是情态动词，意思是“能;可以”，不能独立作谓语，只能与其他动词(原形)一起构成谓语，且没有人称和数的变化。1.表示能力IcanspeakEnglish.

我会讲英语。2.can作为情态动词,可以表示请求或允许。

CanIuseyourpencil?

我可以用一下你的铅笔吗？Youcansitdown.

你可以坐下。3.can也可以用于推测,表示可能性。Tomisintheclassroom.Hecan’tbehere.

汤姆在教室,他不可能在这儿。句型：1.表示能力时变否定句直接在can后加上not即可。can与not可缩写成can’t或cannot。Emmacanplaythepiano.→Emmacan’t/cannotplaythepiano.一般疑问句变一般疑问句时，把can直接移到主语前即可。Icanseeacomputeronthetable.→Canyouseeacomputeronthetable?注意：如果主语是第一人称，变疑问句时通常要改为第二人称。肯定回答用“Yes,主语+can.”；否定回答用“No,主语+can’t.”。2.表示请求或允许时，在口语中常用OK，sure或certainly等作肯定回答；用sorry等作否定回答。--CanIborrowyourpen,please?--Certainly.即时练Acomputer______thinkforitself;itmustbetoldwhattodo.A.can’tB.couldn’tC.maynotD.mightnotA2.–Whoisthemanoverthere?IsitMr.Li?--No,it______behim.Mr.
