【小题1】考查连词。but表示前后是转折关系。and表示前后是并列或递进关系。
【小题2】考查副词。unexpected是形容词；unexpectedly是副词，这里来修饰动词。
【小题3】考查代词。为了上下文的代词的一致性用you .
【小题4】考查固定短语。这里be moved totears感动地流下了眼泪。
【小题5】考查非谓语动词。逗号后是句子，前后没有连词，故用Think的非谓语形式，think与we 之间是主动关系，故用thinking.
【小题6】考查副词。根据句意故用否定句can not wait.
【小题7】考查形容词。sincerely是副词；sincere是形容词，来修饰名词。
【小题8】考查固定短语。a donation of+钱数，捐款多少。
【小题9】考查名词。difficult是形容词；difficulty是名词，放在冠词之后应该用名词。
【小题10】考查动词的被动语态。这里hometown 与rebuilt 之间是被动关系，故用can be rebuilt.
