1、行為動(dòng)詞一般現(xiàn)在時(shí)一我們這里所說(shuō)的行為動(dòng)詞, 指的是除be動(dòng)詞、情態(tài)動(dòng)詞和助動(dòng)詞之外的全部動(dòng)詞。行為動(dòng)詞為數(shù)眾多,主語(yǔ)為第三人稱(chēng)單數(shù)he, she, it時(shí),詞形有變化。當(dāng)主語(yǔ)是第三人稱(chēng)單數(shù)時(shí),行為動(dòng)詞的一般現(xiàn)在時(shí)通常有三種變化: 1.一般在動(dòng)詞原形后加s play-plays like-likes read-reads sing-sings dance-dances cook-cooks 2.以s,x,sh,ch,o結(jié)尾的動(dòng)詞加es go-goes wash-washes watch-watches catch-catches do-does 3.以輔音字母加y結(jié)尾,把y改i再加es fly
2、fliesstudystudies try-tries 4. 如果詞末為o,或o前為輔音字母,加es: go-goes do-does只有第三人稱(chēng)單數(shù)動(dòng)詞才要變,其他人稱(chēng)(I, you ,we ,they)則用動(dòng)詞的原形。(這種變化與名詞的單數(shù)變復(fù)數(shù)有點(diǎn)相像。)二. 肯定式:I/ You/ They/復(fù)數(shù)名詞+ do He/ She/ It/ 單數(shù)名詞+does 三. 否定式:I/ You/ They/復(fù)數(shù)名詞+ do not (dont)后接動(dòng)詞原形 He/ She/ It/ 單數(shù)名詞+does not (doesnt)后接動(dòng)詞原形四. 疑問(wèn)式:一般現(xiàn)在時(shí)的疑問(wèn)式是將助動(dòng)詞do/does提到
3、句首,然后加主語(yǔ)和動(dòng)詞原形。結(jié)構(gòu)是:1). Do + 主語(yǔ)+ 動(dòng)詞原形+其他成分? (注意:回答時(shí)須用人稱(chēng)代詞) Yes,主語(yǔ)+do. / No, 主語(yǔ)+dont2) . Does+主語(yǔ)+動(dòng)詞原形+其他成分? Yes,主語(yǔ)+does. / No, 主語(yǔ)+doesnt.(注意:回答時(shí)須用人稱(chēng)代詞)五. 那么,什么情況下用行為動(dòng)詞的一般現(xiàn)在時(shí)呢?當(dāng)這個(gè)動(dòng)作經(jīng)常發(fā)生或表示習(xí)慣性的動(dòng)作時(shí),通常用一般現(xiàn)在時(shí),它經(jīng)常與表示頻度的時(shí)間狀語(yǔ)連用,如,當(dāng)句子中有every day every year ,on Sunday, in the morning ,often, sometimes, usually,
