问题: 两道选择

Supper_____ ready and let's go and have ______
A.maybe;it
B.may be ;that
C.is;it
D.may be; supper

You have helped make _____ possible for me to have a dog.
a.that
b.this
c.thes
d.it

解答:

1.选C
maybe是副词,不可作谓语;重复出现的supper应用代词it代替
晚饭已经做好了,我们一起去吃吧。
2.选D
it做形式宾语, make的真正宾语是to have a dog,其他三个单词无此用法
你帮我使拥有一只狗成为可能。
