Parentheses(),5 Brackets,4 The Colon:,2 The Comma,Punctuation,like mechanics(such as capitalization,italics,abbreviations,and word-division),has not received due attention in most textbooks on writing or in most writing classes.However,in English punctuation plays a more important part than in Chinese.Thus we believe it is necessary to familiarize ourselves with proper use of punctuation and the role punctuation can play in the process of practicing writing,especially in realization of the goal of being clear,being coherent,being emphatic,being concise,and in a word,being forceful,which are generally thought to be basic qualities of good writing.,Understanding Punctuation,Lets look at the following anecdote.Peter can change the goal of Toms insult simply by using two commas and quotations.,Activity,Example 1,Tom said Peter must be as stupid as an ass.“Tom,”said Peter,“must be as stupid as an ass.”,Understanding Punctuation,Comment:A joking example as it might be,it

the coordinating connective but does not.,Occasionally,in grammar structure test,too,punctuation plays an important role in making the correct choice.,Understanding Punctuation,Study the following example.,Activity,Example 1,Tom has two sisters,Jane and Mary,_.A.Jane being an engineer and Mary,a medical doctorB.Jane is an engineer and Mary,a medical doctorC.Jane was an engineer and Mary,a medical doctorD.Jane,an engineer and Mary,a medical doctor,Understanding Punctuation,Comment:Choice A is correct,because the punctuation mark after the appositive Jane and Mary is a comma,and such a structure requires an absolute structure of the present participle with Jane acting as the logical subject of the phrase being an engineer.But if the punctuation mark after the appositive Jane and Mary is not a comma but a period,then choice B is correct.Accordingly,the comma after the appositive Jane and Mary provides the cue for the correct choice of this multiple-choice question.,Understanding Punctuation,Of course,other means,such as the change of sentence structure,word order,necessary mechanics,etc.,are also in order.,Study the following examples.,Activity,Example

Joyces original sentence is more forceful and accordingly effective.,Examples of punctuation marks enhancing emphasis is found in the use of the dash.The dash requires readers to pause in their process of reading,and thus is more forceful than a comma.We can use dashes to gain emphasis,as long as we use them sparsely.We can use a dash to add emphasis to an idea at the end of a sentence,the position of stress,Understanding Punctuation,Example 2,Emphatic:Maybelle had only one chanceand a slim one at that.,Less emphatic:Maybelle had only one chance,and a slim one at that.,We can use dashes,instead of commas,around an interruption to emphasize the interrupting materials.,Understanding Punctuation,Example 3,Emphatic:My cousin Clydethe crazy one from Kankakeeis running for the

Punctuation,Not emphatic:My cousin Clyde(the crazy one from Kankakee)is running for the legislature.,Example 4,Another way of achieving emphasis is the use of colon,because colon can call readers

attitudes.,The Exclamation Point!,Faulty:After traveling 1.24 billion miles through space,Voyager 2 missed its target by 41 miles!,Sentence 2,Revised:After traveling 1.24 billion miles through
