I only eat vegetables ( scientists call me a herbivore ) -- almost always leaves from the tops of trees .
我只吃蔬菜(科学家称我为草食动物)几乎常常是树梢的叶子。
For example , we know that the teeth of thetyrannosaurus rexare long , slender , and knife-like , similar to those of the komodo dragon ( a carnivore ) , while those of thediplodocusare more flat and stumpy , like those of the cow ( an herbivore ) .
