有关do的所有语法,包括词组,句型

你好, do可作两种词性,一为动词,意思是： 做.eg： I have to do my homework first. 或 She has to do her homework first. 二是助动词,常用于构成句式,在一般现在时中常用,其中,do的单三形式为does,当一般现在时中主语为单数时使用.以下详讲： 一,用于组成一般疑问句.若句中没有系动词和情态动词,就要使用助动词do或does（这里的意思就是,当你看见一般现在时,要求你变一般疑问句时,有系动词就提前系动词,没有系动词就在句前加do或does后面照抄.） eg: I love eating. 改为Do you like eating? eg: She loves eating. 改为Does she love eating? 二,用于组成否定句.同理,如果句中没有系动词或情态动词就在主语后加don't或doesn't. eg:I love eating. 改为,I don`t love eating. eg: She loves eating. 改为,She doesn`t love eating. 三,do与does的区别. 上面已提过,does是do的另一种形式,和do一样本身无实意. 在一般现在时中,分两种情况,当主语是复数和第一人称时,就用do. eg: They do the homework. Do they do the homework? They don`t do the homework. We do the homework. Do you do the homework? We don`t do the homework. 当主语是第三人称单数时,就用does. eg： He/She/It eats the apples. does he/she/it eat the apples? He/She/It doesn`t eat any apples.do 的词组：do a survey 做调查,do exercises做练习,do sports做运动,do wrong做错事,do over 重做,do without 重做.满意速速采纳,谢谢合作!
