do和does的用法及区别.pptx

Do does我来了auxiliary 助动词 动词表示动作状态，但英语里有些动词不表示动作状态，而是协助主动词表示时态或者语态，这类动词叫做助动词（auxiliary verbs) 如：基本助动词：have 、 do、 be等 半主动词：be about to 等 情态助动词：may 、 must、 need等presentatoin1Do you have a baseball ? Yes , I do. / No , I don`t.Does he have a tennis ball ? Yes, he does./ No ,he doesn`t.I don`t like bananas .Do they have a basketball ?He doesn`t have a pen.2作为行为动词，跟其他动词一样，如：study 、play 等，他的意思是”做”等。 如：We usually do our homework in the afternoon.作为助动词一构成一般疑问句。Do you want to answer my question ?二do+not构成否定句I don not want to be the last one .三构成否定的祈使句Hands up .Don`t move !Don`t go there .四用作代词 Do you like Wuqi? Yes ,I do.(do用作代词，代替like Wuqi)注：除第三种用法外，do和 does用法基本相同；do 用于第一人称、第二人称和第三人称复数的形式中Does用于主语第三人称单数的句中）Exercise1___he watch TV at night? Yes , he does.2___you go to school everyday ?
