On the other hand, good punctuation can make your meaning clear and your language effective. English punctuation generally differs from that of other European lan
2、guages; even though there is often considerable room for personal preferences, a mastery of the basic rules is indispensable.There is one overriding principle: to use the bare minimum of punctuation necessary to keep the writing intelligible. The following list of rules makes no claim to exhaustiven
3、ess.I. The Apostrophe ()1. mens, womens, childrens, peoplesIt is correct to write this areas problems, meaning “the problems of this area”, and these areas problems, meaning “the problems of these areas”: in fact, putting apostrophes anywhere else would be wrong. But the plurals of man, woman, and c
4、hild are exceptions to this general rule: thus we write the mens wives, the womens husbands, the childrens mothers, and nothing else.Another important exception is the word people when it denotes the plural of “person”: thus we would write these peoples behavior, meaning “the behavior of these perso
5、ns”, but these peoples behavior, meaning “the behavior of these peoples” (i.e. ethnic groups).Other irregular plurals are treated in the same way as men, women, children, and people: above all the plurals of ox, sheep, goose and mice (e.g. the oxens pasture, the sheeps wool, the geeses flight, the m
6、ices tails).2. A mistake that is frequent among foreign learners of English is to write a phrase such as “these areas problems”, when what the person actually means is these problems of the area. 3. It is best to use the apostrophe when you want to show the plural of something which cannot normally
7、be plural:The past tense of occur is spelt with two rs.I accept the idea in principle, but there are a lot of ifs.4. Strings of apostrophes are to be avoided. Thus one should write the friends of that mans son, instead of “that mans sons friends”.5. We say in ten days time, in twenty years time (i.e
8、. we use the apostrophe). 6. We say each others, not “each others” (e.g. to get on each others nerves).II. The Colon (:) 1. QuotationsThe colon is often used to introduce quotations:To quote Nietzsche: “God is dead!”As the bard (One of an ancient Celtic order of minstrel poets who composed and recit
9、ed verses celebrating the legendary exploits of chieftains and heroes.吟游诗人古代凯尔特族的吟游诗人，自编自唱，吟唱酋长和英雄的传奇业绩) so abruptly puts it:“All the worlds a stage”The colon can also be used to introduce direct speech, especially in rather formal or serious contexts:Finally Mark Antony began his address: “Friends,
10、 Romans, countrymen (compatriots), lend me your ears.”.N.B. (N.B.=拉nota bene (=note well)注意, 留心)i. The colon is not used to introduce conversation.ii. Direct formal quotations begin with a capital letter.iii. The colon is not used to introduce quotes consisting of very brief phrases:Do you know that
11、 Mrs Thatcher actually said “shut up” to Lord Carrington?2. ExplanationsThe colon is often used after a main clause where the following statement explains, elaborates, or illustrates that clause, especially in formal contexts. It may sometimes be replaced by a full stop or a semicolon.There is no po
12、int in worrying: disasters are sure to happen anyway. (Full stop and semicolon also possible.)The Church is totally opposed to two aspects of the permissive society: that is, abortion on demand and artificial methods of birth control.Apartheid (种族隔离) was not overthrown: rather, it died a natural dea
13、th. (Full stop and semicolon also possible.)The question is this: Is killing ever justified?He certainly has a drinking-problem: I once saw him drink a whole bottle of whisky. (Full stop and semicolon also possible.)There is one good thing about skinheads (剃光头的人) and punks: they absolutely hate each
14、 other.3. ListsColons can also be used to introduce lists or enumerations, often using the following phrases: as follows, for example, for instance, such as, and the following.In the world described in Orwells Animal Farm two basic principles become all-important: (i) all animals are equal; (ii) som
15、e animals are more equal than others.Our solar system consists of the following planets (行星): Mercury(水星), Venus(金星), Earth, Mars(火星), Jupiter(木星), Saturn(土星), Uranus(天王星), Neptune(海王星), and Pluto(冥王星).N.B. Try to avoid sentences like the following, where the subject and the verb are separated from
16、the complement:The ingredients of gunpowder are: saltpeter(硝石), sulphur(硫磺), and charcoal.Better would be to remove the colon, or else to rephrase the sentence:The ingredients of gunpowder are as follows: saltpetre, sulphur, and charcoal.or:Gunpowder has three ingredients: saltpeter, sulphur, and ch
17、arcoal.III. The Comma (,)1. Defining and Non-definingCompare the two following sentences (a and b):a. Pop-stars who earn fortunes should pay higher taxes.(Defining relative clause-i.e. only those pop-stars who earn fortunes should pay higher taxes.)b. Pop-stars, who earn fortunes, should pay higher
18、taxes.(Non-defining relative clause - i.e. all pop-stars earn fortunes and therefore should pay higher taxes.)The first sentence refers only to some pop-stars, while the second sentence refers to all pop-stars. Note that in the second sentence there are two commas (not one), to mark the beginning an
19、d the end of the clause.The same principle operates with the words when and where.Compare the following:a. The day when JFK was assassinated I was crossing the Atlantic.b. On November 22, when JFK was assassinated, I was crossing the Atlantic.c. The town where I was stationed was pretty arid.d. Quet
20、ta, where I was stationed, was a pretty arid place.Note that a comma is possible in a (after assassinated), but not in c.The same principle also extends to appositional phrases.Compare the following:a. Nietzsches work The Gay Science was written in 1888.b. Nietzsches last work, The Gay Science(艳体诗),
21、 was written in 1888.c. The famous thinker Michel Foucault has just died.d. A famous thinker, Michel Foucault, has just died.e.The Prime Minister, Margaret Thatcher, has just resigned.f. Margaret Thatcher, the Prime Minister, has just resigned.In a the title of the work is defining, i.e. The Gay Sci
22、ence was only one of several works by Nietzsche. In b the title is non-defining, because only one work can be the authors last. In c Michel Foucault is not the only famous thinker; therefore, the name Michel Foucault is defining, and hence no commas. In d A famous thinker and Michel Foucault are one and the same; therefore, Michel Foucault is non-defining, and hence commas. Sentences e and f are non-defining (and therefore with commas), because in Britain there is only one Prime Minister at any one time.Before we go on, it is impo6
