d,反意疑问句，动词是is,后面用isn't，主语可以用it代替polly（表示鸟）
b，表示就在那是
c,表示 过去完成时，已经教了20年
c,丢东西已经发生了，用had是因为前面用了seemed
d,有for，填延续性动词
D固定用法，多看句子它记住
D不太确定
D有for，用完成时，过去的过去
D有seemed，判断是过去时。不用过去完成时，因为没有一个过去的时间点供参考
D有for，填延续性动词
D.避免与前面的Polly重复
D只能是连词
C后边是过去时，但“教”的动作持续了十年，所以用过去完成式
不太清楚
D应该用动词leave,但是leave不能表示延续，所以用D的方式表现
不好意思，没有回答全
