问题描述：
the largest brain possessed by any dinosaur weighed about a kilogram.要详解这句,
brain possessed by any dinosaur
答
翻译：恐龙所拥有的最大的大脑称重1公斤.
possessed by any dinosaur 是非谓语动词作定语,修饰形容the largest brain.因为possess是及物动词,所以大脑应该是被拥有,要用done表被动.
weighed about ...是真正的谓语动词.所以这句话的主句是the largest brain weighed about a kilogram.
