英語語法基礎(chǔ)知識:動詞的四種時態(tài)
動詞的時態(tài)同學(xué)們經(jīng)常會混淆,下面小編整理了英語語法基礎(chǔ)知識:動詞的四種時態(tài),希望對大家有幫助!
(1)一般現(xiàn)在時:
一般現(xiàn)在時的構(gòu)成
1. be動詞:主語+be(am, is, are)+其它。如: I am a boy. 我是一個男孩。
2. 行為動詞:主語+行為動詞(+其它)。 如: We study English. 我們學(xué)習(xí)英語。
當(dāng)主語為第三人稱單數(shù)(he, she, it)時,要在動詞后加"-s"或"-es"。如:Mary likes Chinese.瑪麗喜歡漢語。
動詞+s的變化規(guī)則
1.一般情況下,直接加-s,如:cook-cooks, milk-milks
2.以s. x. sh. ch. o結(jié)尾,加-es,如:guess-guesses, wash-washes, watch-watches, go-goes
3.以“輔音字母+y”結(jié)尾,變y為i, 再加-es,如:study-studies
(2)一般過去時:
動詞過去式詳解 動詞的過去式的構(gòu)成規(guī)則有:
A、規(guī)則動詞
① 一般直接在動詞的后面加ed:如 worked , learned , cleaned , visited
、 以e結(jié)尾的'動詞直接加d:如 lived , danced , used
③ 以輔音字母加y結(jié)尾的動詞要改y為i再加ed(此類動詞較少)如 study – studied carry – carried worry – worried (注意play、stay不是輔音字母加y,所以不屬于此類)
④ 雙寫最后一個字母(此類動詞較少)如 stopped
B、不規(guī)則動詞(此類詞并無規(guī)則,須熟記)小學(xué)階段要記住以下動詞的原形和過去式:sing – sang , eat – ate ,
