來(lái)源:網(wǎng)絡(luò)來(lái)源 作者:中考網(wǎng)編輯 2019-09-25 11:16:14
中考網(wǎng)整理了關(guān)于2020年中考英語(yǔ)知識(shí)點(diǎn)之現(xiàn)在完成時(shí)注意事項(xiàng),希望對(duì)同學(xué)們有所幫助,僅供參考。
1、一個(gè)句子應(yīng)該用什么時(shí)態(tài)只能取決于它需要表達(dá)的意思,以及它所處的語(yǔ)言環(huán)境。例如:
He speaks English .(一般現(xiàn)在時(shí),說(shuō)明動(dòng)作發(fā)生的經(jīng)常性。)
He spoke English when he was in New Zealand .(一般過(guò)去時(shí),說(shuō)明動(dòng)作發(fā)生的時(shí)間。)
He is speaking English.(現(xiàn)在進(jìn)行時(shí),說(shuō)明動(dòng)作正在進(jìn)行。)
He has spoken English for three years since he came to the USA.(現(xiàn)在完成時(shí),這里說(shuō)明動(dòng)作的總和。)
He has been speaking English since he came to the USA. (現(xiàn)在完成進(jìn)行時(shí),強(qiáng)調(diào)動(dòng)作的連續(xù)性。)
2、在含有時(shí)間狀語(yǔ)從句或條件狀語(yǔ)從句的主從復(fù)合句中,如果主句的謂語(yǔ)動(dòng)詞是一般將來(lái)時(shí),那么從句的謂語(yǔ)動(dòng)詞就只能用一般現(xiàn)在時(shí)來(lái)表示將來(lái)時(shí);如果主句的謂語(yǔ)動(dòng)詞是過(guò)去將來(lái)時(shí),那么從句的謂語(yǔ)動(dòng)詞就只能用一般過(guò)去時(shí)來(lái)表示過(guò)去將來(lái)時(shí)。
例如:I will not play tennis if it rains tomorrow.
I would not play tennis if it rained the next day.
3、 有些動(dòng)詞表示無(wú)法持續(xù)的動(dòng)作,它們一般不宜用于進(jìn)行時(shí)態(tài)中。這類動(dòng)詞常見的有:be , believe , consist , find , forget , hate , have , hope , hear , know , like , love , notice , prefer , remember , see , seem , smell , suggest , taste , understand , want , wish , sit down , stand up 等等。
