這里講的挺細(xì)的,復(fù)制給你看一下
I think后可接賓語(yǔ)從句,當(dāng)賓語(yǔ)從句要表示否定時(shí),應(yīng)將否定形式轉(zhuǎn)移成動(dòng)詞think的否定形式.
此句型只限于主句謂語(yǔ)動(dòng)詞為believe,expect,suppose,imagine,feel等動(dòng)詞.
當(dāng)主語(yǔ)為第一人稱,其反意疑問(wèn)句與賓語(yǔ)從句的主語(yǔ)和謂語(yǔ)一致.
例如:I don”t think this is worth trying.我認(rèn)為這不值得一試.
I don”t think you can do it,can you?我認(rèn)為你做不了這件事,你能嗎?
如果表示我不認(rèn)為...,可以說(shuō)：I don”t think so.我認(rèn)為不是這樣.
當(dāng)認(rèn)為對(duì)方所說(shuō)是對(duì)的,可說(shuō)I think so.;
當(dāng)認(rèn)為對(duì)方所說(shuō)不對(duì),可說(shuō)I don”t think so..
I don”t think so.可以視為是對(duì)Do you think so?的否定應(yīng)答.
Do you think so?與Don”t you think so.意思稍有不同.
前者為一般地詢問(wèn)對(duì)方,后者帶有希望對(duì)方贊同自己的看法的含義.
例如:Can you get down?I think so.你能下來(lái)嗎?我想能下來(lái).
Can you take these things to my room?Sorry,I don”t think so.你能把這些東西拿到我房間去嗎?對(duì)不起,我想我不能.
