Question

8．He got a C on his paper!He ought to read a lot and put more work into it．

Answer 1

分析 他考試得了C．他本應(yīng)該多讀書更努力學(xué)習(xí)的．

解答 答案：read前加have．考查情態(tài)動詞的完成式．因為He got a C on his paper!所以后句表示"他本應(yīng)該多讀書更努力學(xué)習(xí)的．"，所以謂語動詞用ought to have read，表示"本應(yīng)該做而沒有做"．

點評 考查情態(tài)動詞的完成式．
ought to與 should的用法區(qū)別如下
1．一般說來，兩者可替換，只是ought to語氣稍重．如：
You ought to[should]go and see Mary．你應(yīng)該去看看瑪麗．
2．表示出于法令規(guī)則、行為準(zhǔn)則、道德責(zé)任等客觀情況而"應(yīng)該"做某事時，一般應(yīng)用ought to，若用should則含有個人意見，強(qiáng)調(diào)主觀看法．如：
We ought to go and see Mary tomorrow，but I don't think we will．明天我們按理應(yīng)該去看看瑪麗，但是我認(rèn)為我們不會去（此句不宜用should）．
3．在公告、須知或條例中，出于禮貌，常用should．如：
You should not run alongside the swimming-pool．不準(zhǔn)在游泳池邊奔跑
