He was so tired that he left the diffcult work half____,and went back home.
A.do B.done C.doing D.to do
翻译一下,还有为什么选B不选C :工作是被做的.被动.c 主动.
Among those ships are none____ to us.
A.belonged B to be belonged C.belonging D.belongs
也翻译一下,再解释一下为什么选C：
此题是倒装句：none among these ships are belonging to me .
belong to 属于.现在进行时.
在这些船中没有一艘属于我.
