答案：

1. C) 【句意】 他独自一人开始经商，并且做得很成功。

【难点】on one’s own 是个常用的介词词组，意为“独自”；of one's own表示“某人自己的(东西)”，如：I have a flat of my own.我自己有套房子。

2. C) 【句意】 约翰的考试分数全班最高；他昨天晚上一定学习了。

【难点】 表示对过去某一动作行为的猜测须要用must have done这一句型结构。

3. B) 【句意】 弗兰克几乎从未受过任何教育，是不是?

【难点】 这是一句含有否定副词never的一般过去时的句子，由于主句为否定形式，所以反意问句用肯定形式。

4. C) 【句意】 即使他的信明天到也无济于事了。

【难点】 在条件句中表示现在将来的时间，需要用一般现在时，主句中使用将来时。

5. C) 【句意】 我们在房间的后面也能听得很清楚。

【难点】as well意为“(程度)同样地好”，是副词短语修饰动词hear；just表示程度，意为“刚好”。
