Question

18．我認(rèn)為父母沒(méi)有必要阻止孩子參加不同的社團(tuán)．
I don't think it's necessary for parents to stop their children from joining different clubs．

Answer 1

分析 I don't think it's necessary for parents to stop their children from joining．

解答 答案：I don't think it's necessary for parents to stop their children from joining．這里是所客觀事實(shí)用一般現(xiàn)在時(shí)，我們需要用賓語(yǔ)從句來(lái)表達(dá)，主句是我認(rèn)為I think，余下的作為think的賓語(yǔ)從句，父母沒(méi)有必要阻止孩子參加不同的社團(tuán)是否定句，此時(shí)需要將否定轉(zhuǎn)移到主句上，故主句是I don't think，表示對(duì)某人來(lái)說(shuō)做某事是怎么樣的用It's+adj+for sb．to do sth．這里必要的necessary，父母parents，阻止某人做某事stop sb from doing sth，他們的孩子their children，加入社團(tuán)用join，故答案是I don't think it's necessary for parents to stop their children from joining．

點(diǎn)評(píng) 動(dòng)詞think，believe，suppose，imagine，expect，feel的主語(yǔ)是第一人稱、謂語(yǔ)動(dòng)詞為沒(méi)有任何副詞修飾的一般現(xiàn)在時(shí)，它們的否定式實(shí)際上是對(duì)賓語(yǔ)從句或復(fù)合符合賓語(yǔ)或狀語(yǔ)的否定．表示說(shuō)話者提出一種委婉的看法或主張，即將not從賓語(yǔ)從句的謂語(yǔ)動(dòng)詞的前面，轉(zhuǎn)移到了主句謂語(yǔ)動(dòng)詞think，believe，suppose等的前面．即（否定前移） 
e．g．：I'm sorry，but I don't think I know you．對(duì)不起，我想我并不認(rèn)識(shí)你．（否定賓語(yǔ)從句）   
I don't find the story interesting．我認(rèn)為這個(gè)故事沒(méi)有趣．（否定復(fù)合賓語(yǔ)）
