【第3篇 小學(xué)五年級(jí)英語(yǔ)語(yǔ)法總結(jié):be動(dòng)詞用法
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)肯定陳述句中本來是沒有助動(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。
強(qiáng)調(diào)一點(diǎn),有some的要考慮是否要用any。
