1、初三英語(yǔ)中考語(yǔ)法考點(diǎn)重難點(diǎn)詳解(37)助動(dòng)詞的功能：幫助主動(dòng)詞，表達(dá)“時(shí)”和“數(shù)”的概念這一篇，我們講解一下助動(dòng)詞的功能。謂語(yǔ)中如果出現(xiàn)助動(dòng)詞, 就是說(shuō)謂語(yǔ)局部有兩個(gè)(甚至三個(gè))局部組成，一般最前面的哪個(gè) 局部反映出時(shí)間和數(shù)的概念。比方：has說(shuō)明的時(shí)間是現(xiàn)在，數(shù)是單三Lunch has been cooked.午飯已經(jīng)準(zhǔn)備好了。這句中，has的功能是表現(xiàn)lunch的單復(fù)數(shù)，也說(shuō)明“現(xiàn)在” 已經(jīng)完成。does表示時(shí)間是現(xiàn)在，主語(yǔ)是單數(shù)Does he have a job?他有事做嗎？does說(shuō)明問(wèn)的時(shí)間是現(xiàn)在，問(wèn)的對(duì)象是單三的。is表示時(shí)間的現(xiàn)在，主語(yǔ)是單數(shù)This room is very

2、untidy.這個(gè)房間很亂。He is the man I served yesterday.他是我昨天接待的人。is說(shuō)明主語(yǔ)是單數(shù)，同時(shí)表達(dá)的情況是現(xiàn)在。was時(shí)間是過(guò)去，主語(yǔ)是單數(shù)Mom was preparing dinner when I got home.我至I家時(shí)，媽媽在準(zhǔn)備晚飯。was和主語(yǔ)的單數(shù)一致,并且說(shuō)明的時(shí)間概念是“過(guò)去”同樣，如果為配合主語(yǔ)的復(fù)數(shù)形式，助詞會(huì)選擇are,were,have以及do ,謂語(yǔ)動(dòng)詞的單復(fù)數(shù)在時(shí)態(tài)中的表現(xiàn)鞏固與拓展練習(xí)f it is fine tomorrow, wea football match.a. have b. will have c.
