I read the last part of the article. I think it’s easier than others because I understood in a short time. There are several verbs which have two or more than features. Such as “desire”, “name”. For the name example, as a verb, it means “give a name to say what the name of is”; as a noun, it means “the words that someone or something is called for or know by”. Actually, it’s familiar for us. however, it’s difficulty (difficult)that we have to distinguish the feature from its several features. Not only from itself have we distinguished, but also from the whole sentence even (the)whole paragraph.
It’s a great big work if we understand the features of words one by one.
About happiness, this is the thing that we will spend our whole life to hanker. Whatever the happiness we get, which is (去掉is)happiness we wish. The greatest happiness is depended on ourselves.
