說(shuō)明:引用此文請(qǐng)注明出處,并務(wù)請(qǐng)保留后面的有效鏈接地址,有網(wǎng)友問(wèn)：為什么有的書(shū)上又說(shuō)情態(tài)動(dòng)詞后接動(dòng)詞完成式呢?現(xiàn)回答如下：▲情態(tài)動(dòng)詞后必須接動(dòng)詞原形,不能接帶to不定式或動(dòng)名詞等.如：我們應(yīng)當(dāng)學(xué)講流利正確的英語(yǔ).誤：We must to learn to speak English fluently and correctly.誤：We must learning to speak English fluently and correctly.正：We must learn to speak English fluently and correctly.▲注意,我們說(shuō)的“動(dòng)詞原形”指的是緊跟在情態(tài)動(dòng)詞后面的那個(gè)動(dòng)詞用原形.事實(shí)上,情態(tài)動(dòng)詞后面的動(dòng)詞可用進(jìn)行式、完成式、被動(dòng)式等,只要保證第一個(gè)詞是“原形”就行了.如：She might be waiting for you.她可能在等你.You must have seen him.你一定見(jiàn)過(guò)他了.She may have missed her train.她可能誤火車(chē)了.The road may be blocked.這條路可能不通了.引用地址:
