eating是动名词。动名词是英语中动词的非谓语形式的一种，起名词的作用。在动名词的短语中，动名词还保留动词的属性，如可以带自己的宾语、状语等。动名词做主语的几种类型：
直接位于句首做主语。
Swimming is a good sport in summer. 在夏天，游泳是一项好的体育运动。
用it作形式主语，把动名词（真正的主语）至于句末作后置主语。
It is no use telling him not to worry. 告诉他不用担心是没有用的。
用于 “There be”结构中。
There is no saying when he’ll come. 很难说她何时回来。
用于布告形式的省略结构中。
No smoking. 禁止吸烟。
No parking. 不准停车。French fries are made from potatoes. 炸薯片是土豆做的。
be made form用……制造
【辨析】：be made of与be made from
两者都表示“用……制造”，但be made of表示原材料往往经过无力变化，仍可看得出材料的原样；而be made from则表示原材料经过化学变化，以看不出其原样了。如：
This chair is made of wood. 这把椅子是木质的。
Paper is made from wood. 纸是木头造的。
The drink is made of apples. 这种饮料是用苹果作原料制成的。【拓展】：
made与不同的介词搭配，构成具有不同含义的短语，如：be made in“在……地方制造”，后接表示地点的名词；be made by“由（被）……（人）制作”，后接表示人的名词或代词；be made into“（某物）被制作成……”；be made with“（某五）是由（某种工具）制造而成的”。
