2) human being表示“人,人类”,是由“human”和“being”构成的。human意为“人(类)的”,being意为“存在物;生物;人”,合为human being (人类)。其复数形式是在being后加-s。如: a human being 一个人,five human beings 五个人。

Could you explain the answer to me?
你能给我解释一下这个答案吗?

Edison invented the electric bulb. 爱迪生发明了电灯泡。 4. When the bowl was filled with hot water, the wine would get warm.  当碗里(被)盛满热水,酒就变热了。 解析: be filled with意为“(被)盛满;(被)装满”,是fill...with...的被动结构,暗示外界主语“使……充满……”。如: The bowl was filled with oil.  碗里(被)装满了油。 另外,be full of也可表示“充满”,强调“充满的状态”;be filled with强调用于充满的“事物”。试比较: The pool was full of water. 池子里装满了水。 The pool was filled with water.  池子里(被)注满了水。                                                                                                         湖南 厉继选
