▲高考英語(yǔ)語(yǔ)法必考知識(shí)點(diǎn):動(dòng)詞不定式的否定式

Tell him not to shut the window…

▲高考英語(yǔ)語(yǔ)法必考知識(shí)點(diǎn):動(dòng)詞不定式的否定式

動(dòng)詞不定式的否定形式通常是在不定式符號(hào)to的前面加上not,如果是不帶to的不定式就直接在動(dòng)詞原形前面加上not. For example:

I tell him to go to the playgound 否定形式為 I tell him not to go to the playgound 這就是不定式的否定。 如果按照你說(shuō)的把動(dòng)詞否定: I don't tell him to go to the playgound. 這話就成了我沒(méi)告訴他去操場(chǎng)。強(qiáng)調(diào)的是告訴還是沒(méi)告訴。而不定式的否定強(qiáng)調(diào)的是不要去操場(chǎng)。就是不能去那里。二者強(qiáng)調(diào)的重點(diǎn)不同。
