答案詳解：
6. C
句意：他獨(dú)自一人開始經(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

8. B
句意：弗蘭克幾乎從未受過任何教育，是不是?
難點(diǎn)：這是一句含有否定副詞never的一般過去時(shí)的句子，由于主句為否定形式，所以反意問句用肯定形式。
9. C
句意：即使他的信明天到也無濟(jì)于事了。
難點(diǎn)：在條件句中表示現(xiàn)在將來的時(shí)間，需要用一般現(xiàn)在時(shí)，主句中使用將來時(shí)。
10. C
句意：我們在房間的后面也能聽得很清楚。
難點(diǎn)：as well意為“(程度)同樣地好”，是副詞短語修飾動詞hear;just表示程度，意為“剛好”。
