答案詳解：
6. C
句意：他獨(dú)自一人開(kāi)始經(jīng)商，并且做得很成功。
難點(diǎn)：on one's own 是個(gè)常用的介詞詞組，意為“獨(dú)自”;of one'sown表示“某人自己的(東西)”，如：I have a flat of my own.我自己有套房子。
7. C
句意：約翰的考試分?jǐn)?shù)全班最高;他昨天晚上一定學(xué)習(xí)了。
難點(diǎn)：表示對(duì)過(guò)去某一動(dòng)作行為的猜測(cè)須要用must have done這一句型結(jié)構(gòu)。
8. B
句意：弗蘭克幾乎從未受過(guò)任何教育，是不是?
難點(diǎn)：這是一句含有否定副詞never的一般過(guò)去時(shí)的句子，由于主句為否定形式，所以反意問(wèn)句用肯定形式。
9. C
句意：即使他的信明天到也無(wú)濟(jì)于事了。
難點(diǎn)：在條件句中表示現(xiàn)在將來(lái)的時(shí)間，需要用一般現(xiàn)在時(shí)，主句中使用將來(lái)時(shí)。
10. C
句意：我們?cè)诜块g的后面也能聽(tīng)得很清楚。
難點(diǎn)：as well意為“(程度)同樣地好”，是副詞短語(yǔ)修飾動(dòng)詞hear;just表示程度，意為“剛好”。
