小學(xué)五年級(jí)英語(yǔ)時(shí)態(tài)知識(shí)點(diǎn)
1、一般現(xiàn)在時(shí):概念:經(jīng)常、反復(fù)發(fā)生的動(dòng)作或行為及現(xiàn)在的某種狀況。
時(shí)間狀語(yǔ):often(經(jīng)常),usually(通常),always(總是),sometimes(有時(shí)),every week(day,year,month...), on Sundays,…
基本結(jié)構(gòu):①be動(dòng)詞;②行為動(dòng)詞
否定形式:① am /is /are +not;②此時(shí)態(tài)的謂語(yǔ)動(dòng)詞若為行為動(dòng)詞,則在其前加don't,如主語(yǔ)為第三人稱單數(shù),則用doesn't,同時(shí)還原行為動(dòng)詞。
一般疑問(wèn)句:①把be動(dòng)詞放于句首;②用助動(dòng)詞 do提問(wèn),如主語(yǔ)為第三人稱單數(shù),則用does,同時(shí),還原行為動(dòng)詞。
2、現(xiàn)在進(jìn)行時(shí):
概念:表示現(xiàn)階段或說(shuō)話時(shí)正在進(jìn)行的動(dòng)作及行為。
時(shí)間狀語(yǔ):now,look,listen,…
基本結(jié)構(gòu):am/is/are +doing
否定形式:am/is/are +not+doing
一般疑問(wèn)句:把be動(dòng)詞放在句首
小學(xué)五年級(jí)英語(yǔ)否定句知識(shí)點(diǎn)
be動(dòng)詞(am、is、are)+not、情態(tài)動(dòng)詞can+not、
助動(dòng)詞(do、does)+not
如何將一個(gè)肯定的陳述句改為否定句:
1、看句中有無(wú)be動(dòng)詞,如有,直接在be動(dòng)詞后+not。
2、看句中有無(wú)情態(tài)動(dòng)詞,如有,直接在情態(tài)動(dòng)詞后+not。
3、如上述二者都沒(méi)有,就應(yīng)用助動(dòng)詞+not。分四個(gè)步驟:
(1)肯定陳述句中本來(lái)是沒(méi)有助動(dòng)詞的,要加上去,位置在主語(yǔ)(某人或某物)后,動(dòng)詞前。
(2)確定助動(dòng)詞用do、does,根據(jù)句中動(dòng)詞,動(dòng)詞是原形的助動(dòng)詞就用do,動(dòng)詞是第三人稱單數(shù)的助動(dòng)詞就用does。
(3)在助動(dòng)詞后加not。
(4)原句中動(dòng)詞假如發(fā)生變化就要恢復(fù)成原形。
