高考英语语法:2010年高考典型例题分析讲解八

1．The boy ______ jump into the river from the bridge.
A．dareB．dares toC．daresD．dared
分析：A项中的dare作为情态动词，仅用于否定句或疑问句。在肯定句中是实义动词，后面要接带to的不定式。正确答案为B项。

2．----Why! I couldn't get you on the telephone this morning.
----We ______ tennis in the yard when you phoned.
A．must be playingB．could be playing
C．must have playedD．must have been playing
分析：通过时间状语从句when you phoned，表明此题要用"must + have been + 动词-ing形式"对过去事情表示推测，所以D项为正确答案。

3．----I stayed at a hotel while in New York.
----Oh, did you? You ______ with Barbara.
A．could have stayedB．could stay
C．would stayD．must have stayed
分析：本题考查情态动词+完成不定式的用法。a hotel是泛指，表类别，意为住旅社，而不住亲戚家或朋友家。must have stayed 是极为肯定的推测。住旅社可能是任意一家，不一定是和Barbara住一起。D项在语气上也与 did you不连贯，故选 A。

4．----When can I come for the photos? I need them tomorrow afternoon.
----They ______ be ready by 12:00.
A．canB．shouldC．mightD．need
分析：should表示略微游疑的推测，既回答了顾客的询问，不失礼貌，又为照片有可能尚未洗好，顾客到时取不到留下了回旋的余地，故答案为B。

5．A rich man ______about his next meal.
A. does not need to worryB. does not need worry
C. needs not worryD. needs not to worry
分析：need作行为动词时的用法：need to do sth; don't need to do sth.；作情态动词时的用法：need do sth. ; need not do sth.根据题意答案选A项。

6.Someone has______ you should______ the area of skin at once.
A. burnt; coldB .burned; cool
C. burning; coldD. some burns; cool
分析：选项D中的burns是名词。burn可用作名词：injury, mark made by fire, heat or acid(由火、热或酸类物造成的)烧伤；灼伤。cold不能用动词，而表示"使……冷却"，我们可用动词cool. 正确答案为D项。
