又一道奇怪的语法题
This kind of dog has a long tail,________ rather like a wolf.
A.looks B.looked C.look D.looking
答案为什么会是A
请帮忙分析下 句子结构
我选的是D looking rather like a wolf.做伴随状语
选A的话 句子不是成了2个谓语了.
非限制定语从句的话：
不是This kind of dog that has a long tail,looks rather like a wolf.
就是This kind of dog has a long tail,which looks rather like a wolf.
