1．The boy ______ jump into the river from the bridge.

　　A．dare　　B．dares to　　C．dares　　D．dared

　　分析：A項中的dare作為情態動詞，僅用于否定句或疑問句。在肯定句中是實義動詞，后面要接帶to的不定式。正確答案為B項。

　　2．----Why! I couldnt get you on the telephone this morning.

　　　----We ______ tennis in the yard when you phoned.

　　A．must be playing　　B．could be playing

　　C．must have played　　D．must have been playing

　　分析：通過時間狀語從句when you phoned，表明此題要用must + have been + 動詞-ing形式對過去事情表示推測，所以D項為正確答案。

　　3．----I stayed at a hotel while in New York.

　　　----Oh, did you? You ______ with Barbara.

　　A．could have stayed　　B．could stay

　　C．would stay　　　　　　D．must have stayed

　　分析：本題考查情態動詞+完成不定式的用法。a hotel是泛指，表類別，意為住旅社，而不住親戚家或朋友家。must have stayed 是極為肯定的推測。住旅社可能是任意一家，不一定是和Barbara住一起。D項在語氣上也與 did you不連貫，故選 A。

　　4．----When can I come for the photos? I need them tomorrow afternoon.

　　----They ______ be ready by 12:00.

　　A．can　　B．should　　C．might　　D．need

　　分析：should表示略微游疑的推測，既回答了顧客的詢問，不失禮貌，又為照片有可能尚未洗好，顧客到時取不到留下了回旋的余地，故答案為B。

　　5．A rich man ______about his next meal.

　　A. does not need to worry　　B. does not need worry

　　C. needs not worry　　　　　　D. needs not to worry

　　分析：need作行為動詞時的用法：need to do sth; dont need to do sth.；作情態動詞時的用法：need do sth. ; need not do sth.根據題意答案選A項。

　　6.Someone has______ you should______ the area of skin at once.

　　A. burnt; cold　　　B .burned; cool

　　C. burning; cold　　D. some burns; cool
