5. ______ tired, after a hard work, she fell into bed and went straight to sleep.

    A. Felt                B. Feeling            C. Being felt            D. To feel

答案及解析：

1.    B。so …that句型的倒装结构。so + 形容词或副词 + 助动词 + 主语 + that 从句。

2.    C。live是receive的主语，所以应该用主动语态，而receive education发生在过去而又对现在产生影响，应该选用完成时态来表达已完成的动作。

3.    B。convinced that=they were convinced that“他们确信”convince意为“使某人相信”，故“他们确信”要用被动语态，they were 可省略。

4.    A。either/neither/each of + n 作主语，谓语用单数。

5.    B。不定式结构表示还没有发生的动作，所以D项不符合题意“她觉得很累，所以去睡觉了”；由于分词结构作状语的逻辑主语就是句子的主语，可以判断she就是feel的逻辑主语，它们之间是主动关系，所以应该选现在分词。A和C项均为过去分词形式，表被动。
