30．A本題是日常交際用語(yǔ)的考查�？忌�解此題的關(guān)鍵是理解題干的含義：“你有桔子和蘋(píng)果嗎?”故A選項(xiàng)符合題意

(六)

29．C本題是詞類的辨析。except表示“除了”，排除的事物不包括在主語(yǔ)的范圍內(nèi)。except for表示“美中不足”。except that表示“除了”，后接從句。besides表示“除了”，排除的事物包括在主語(yǔ)的范圍內(nèi)。

28．A本題是慣用法的考查。but后引導(dǎo)的動(dòng)詞通常情況下用to d0，但若but前出現(xiàn)動(dòng)詞do，則省略to，直接使用動(dòng)詞原形。

27．B本題是情態(tài)動(dòng)詞考查。關(guān)鍵是理解句意：“即使你失敗很多次，也得保持良好的心態(tài)。”must意為“必須”，不符題意；can通常表示能力；should表示“應(yīng)該”。所以will表示對(duì)將發(fā)生的事作一推測(cè)。
