6. Usecommas to separate two or more coordinate adjectives that describe the samenoun.
The 1) relentless, 2) powerful 3) summer sun beat down on them. (1-2 arecoordinate; 2-3 are non-coordinate.)
The 1) relentless, 2) powerful, 3) oppressive sun beatdown on them. (Both 1-2 and 2-3 are coordinate.)

Commas AfterIntroductions
Introductory clauses start with adverbs like after, although, as, because, before, if,since, though, until, when, etc.
When to Use a Comma
Introductory elements often require a comma, but notalways. Use a comma in the following cases:
·After an introductory clause. (Does the introductory element have a subject and verb ofits own?)
·After a long introductory prepositional phrase ormore than one introductory prepositional phrase. (Are there more than five words before the main clause?)
When notto Use a Comma
Do not use a comma in the following cases:
·After a briefprepositional phrase. (Is it asingle phrase of less than five words?)
·After a restrictive(essential) appositive phrase.
Commas vs.Semicolons in Compound Sentences
Comma (,)
Use a commaafter the first independent clause when you link two independent clauses withone of the following coordinating conjunctions:and, but, for, or, nor, so, yet. For example:
I am going home, and I intend to stay there.
Semicolon (;)
Use a semicolonwhen you link two independent clauses with no connecting words. For example:
I am going home; I intend to stay there.
You can also use a semicolon when you join two independent clauses together with one of thefollowing conjunctive adverbs (adverbs thatjoin independent clauses): however, moreover, therefore, consequently,otherwise, nevertheless, thus, etc. For example:
I am going home; moreover, I intend to stay there.
第十八讲 Dangling Modifiers
Strategiesfor revising dangling modifiers:
1. Name theappropriate or logical doer of the action asthe subject of the main clause:
2. Change the phrase that dangles into a complete introductoryclause by naming the doer of the action in thatclause:
Withoutknowing his name, it was difficult to introduce him.
should bechanged: Because Maria did not know his name, it was difficult to introduce him.
3. Combine the phraseand main clause into one:
Toimprove his results, the experiment was done again.
shouldbe changed: He improved his results by doing the experiment again.
