Unit2核心詞匯教材核心詞匯知識(shí)鏈接及典例解讀教材核心詞匯知識(shí)鏈接及典例解讀一、fewadj.&pron.不多;很少1.Havehave用作實(shí)義動(dòng)詞時(shí)一般表示“有”，第三人稱單數(shù)是has。1.

一般來(lái)說(shuō)，在一般現(xiàn)在時(shí)中，主語(yǔ)是第三人稱單數(shù)時(shí)，謂語(yǔ)動(dòng)詞have用has的形式；主語(yǔ)是其他人稱時(shí)用have。如：Ihaveanelderbrother.

我有一個(gè)哥哥。Hehastwopencils.

他有兩支鉛筆。2.

變一般疑問(wèn)句時(shí)，通常需借助助動(dòng)詞do或者does。主語(yǔ)第三人稱單數(shù)時(shí)用does，has還原為have；其他人稱用do，即“Do/Does+主語(yǔ)+have+...?”。如：Doyouhavebrothers?

你有兄弟嗎？Doesshehaveanypencils?

她有鉛筆嗎？3.

變否定句時(shí)，一般在have前加don't；在has前加doesn't，此時(shí)has還原為have，即“主語(yǔ)+don't/doesn'thave+...”。如：Shedoesn'thaveanypencils.

她沒(méi)有鉛筆。Theydon'thavechildren.

他們沒(méi)有孩子。注意：在有些含有have的短語(yǔ)中，have不再表示“有”如：havebreakfast/lunch/supper

吃早/中/晚飯haveacold

感冒/著涼haveagoodrest

好好休息haveaheadache/stomachache/toothache...我頭疼/肚子疼/牙疼……h(huán)avefun

玩得高興haveagoodtime

過(guò)得愉快havealook
