一道英语语法题(sat)请大家帮忙~
Although my brother and I took our dogs to the same training school,my dog won more awards at obedience trials (than my brother).
正确答案是than my brother's dog
为什么不能是but my brother's dog won fewer awards
比较的不应该是奖么?

Although my brother and I took our dogs to the same training school,my dog won more awards at obedience trials than my brother's dog (did)比较的是狗狗获奖 won awards.句子后面省略了did,did指代won award...请问什么时候可以省略呢?是只会省略动词么?基本上都可以省略,是的,be动词和do动词都省略 例如I am older than you (are) are省略
