英语语法概念：argument
In linguistics, an argument is an expression that helps complete the meaning of a predicate, the latter referring in this context to a main verb and its auxiliaries. In this regard, the complement is a closely related concept. Most predicates take one, two, or three arguments. A predicate and its arguments form a predicate-argument structure. The discussion of predicates and arguments is associated most with (content) verbs and noun phrases (NPs), although other syntactic categories can also be construed as predicates and as arguments. Arguments must be distinguished from adjuncts. While a predicate needs its arguments to complete its meaning, the adjuncts that appear with a predicate are optional; they are not necessary to complete the meaning of the predicate. Most theories of syntax and semantics acknowledge arguments and adjuncts, although the terminology varies, and the distinction is generally believed to exist in all languages.

Thespis (6th century BC) of Icaria (present-day Dionysos, Greece), according to certain Ancient Greek sources and especially Aristotle, was the first person ever to appear on stage as an actor playing a character in a play (instead of speaking as him or herself). In other sources, he is said to have introduced the first principal actor in addition to the chorus.

修辞概念： satire
Satire is a genre of literature, and sometimes graphic and performing arts, in which vices, follies, abuses, and shortcomings are held up to ridicule, ideally with the intent of shaming individuals, corporations, government, or society itself into improvement. Although satire is usually meant to be humorous, its greater purpose is often constructive social criticism, using wit to draw attention to both particular and wider issues in society.
A feature of satire is strong irony or sarcasm — “in satire, irony is militant”— but parody, burlesque, exaggeration, juxtaposition, comparison, analogy, and double entendre are all frequently used in satirical speech and writing. This “militant” irony or sarcasm often professes to approve of (or at least accept as natural) the very things the satirist wishes to attack.
