Most of the peopledon't think middle school students should spend too much time playing computer games．Otherwise，it's bad not only for eyesight but also for health．

Answer 1

分析 don't think middle school students should spend too much time  playing．

解答 答案：don't think middle school students should spend too much time  playing．結(jié)合句意表達(dá)的是客觀事實(shí)用一般現(xiàn)在時(shí)，表示認(rèn)為用think，后加賓語從句，從句表達(dá)的是中學(xué)生不應(yīng)花太多時(shí)間玩電腦，主語 middle school students，應(yīng)該should，后加not構(gòu)成否定，故should not，花時(shí)間做某事spend+時(shí)間+doing sth，too much太多，修飾不可數(shù)名詞time，玩電腦play computer games，故從句 students should not spend too much time  playing，此時(shí)將從句的否定轉(zhuǎn)移到主句，主句主語Most of the people復(fù)數(shù)，借助于do構(gòu)成否定，故答案是don't think middle school students should spend too much time  playing．

點(diǎn)評 將think，believe，suppose，expect，fancy，imagine等動(dòng)詞后面賓語從句的否定詞轉(zhuǎn)移到主句中，即主句的謂語動(dòng)詞用否定式，而從句的謂語動(dòng)詞用肯定式．
　 I don't think I know you．我想我并不認(rèn)識你．
　 I don't believe he will come．我相信他不回來．
注意：若謂語動(dòng)詞為hope，賓語從句中的否定詞不能轉(zhuǎn)移．
　 I hope you weren't ill．我想你沒有生病吧．
