小题6:as it was
小题7: remains a mystery
题目分析：
小题1:考查使役动词的用法：hold+宾语+形容词“使…处于…状态”，根据Now Polly wanted to run,可知用一般过去式：held;形容词 still“不动的”。
小题2:考查词组：帮助某人“come to one’s aid/help或come to help sb。从上文的：Whenever we are in trouble,可知是“帮助我们”：come to our aid/help”(或“came to help us/came and helped us”)
小题3:考查词组“和…相反”：contrary to。
小题4:考查词组“受够了”have enough of，从下文的：He always plays his CDs so loud that I cannot study at all和所给的格子，用现在完成时：have had enough of
小题5:考查部分否定：Not all不是所有的都，还有词组“演变”，用被动语态： developed
小题6:考查方式状语从句：as it was正如过去的样子。
小题7: 考查主谓一致：主语是How this compass works 谓语用单数，仍然是“remain+名词”，所以填remains a mystery
