Unit2核心词汇教材核心词汇知识链接及典例解读教材核心词汇知识链接及典例解读一、fewadj.&pron.不多;很少1.Havehave用作实义动词时一般表示“有”，第三人称单数是has。1.

一般来说，在一般现在时中，主语是第三人称单数时，谓语动词have用has的形式；主语是其他人称时用have。如：Ihaveanelderbrother.

我有一个哥哥。Hehastwopencils.

他有两支铅笔。2.

变一般疑问句时，通常需借助助动词do或者does。主语第三人称单数时用does，has还原为have；其他人称用do，即“Do/Does+主语+have+...?”。如：Doyouhavebrothers?

你有兄弟吗？Doesshehaveanypencils?

她有铅笔吗？3.

变否定句时，一般在have前加don't；在has前加doesn't，此时has还原为have，即“主语+don't/doesn'thave+...”。如：Shedoesn'thaveanypencils.

她没有铅笔。Theydon'thavechildren.

他们没有孩子。注意：在有些含有have的短语中，have不再表示“有”如：havebreakfast/lunch/supper

吃早/中/晚饭haveacold

感冒/着凉haveagoodrest

好好休息haveaheadache/stomachache/toothache...我头疼/肚子疼/牙疼……havefun

玩得高兴haveagoodtime

过得愉快havealook
