Answer 1

第一题 提问中是a watch，是泛指，而不是特指，所以排除A。c,d是否定的回答，应该是，我已经有了一只手表。这里的手表也没有特指。所以不能用it或者是The watch。
2， 这个，不解释。。。。大家都知道
3，应该用宾格。只有选A。
4， 主语是What he has done,应该用does，代词指代what, 所以用it。
5，这是主人对来访者说的，所以用you。
6，it做形式主语。真正的主语是后边的He……。这道题个人觉得可以选D耶。因为that从句可以当doubt的定语从句撒。
7,本来是it is sundayd, 因为这里做的是原因状语，所以用It being Sunday。
8，没有there has的用法。lies和lives和据以不符。stands这里意思是挺立。
以上答案仅供参考，嘿嘿。。
