co n ju n ctive adverb, + independent cỉau se Notice the punctuation: a semicolon íoỉlovvs the firsí independent clause, and a comma follows the conjunctive adverb Also, just like the FAN BOYS coordinators, conjunctive adverbs express relationships betvveen the clauses The following chart shovvs the coordinators and conjunctive adverbs that express similar meanings confirmed: proved that they vvere correct 175 Part lfl Sentence Structure C o m p o u n d S e n te n c e : w ith C O IIju n c iìv e A d v e rb s C0NJUNCT1VE ADVERBS COORDINATORS besides íurthermore and moreover also hovvever but nevertheless yet nonetheless or otherwise SENTENCE Community colleges offer preparalion for many occupations;

What sentences State the main ideas? What method o f organization is used to develop the first paragraph? Complex Sentences A complex sentence contains one independent clause and one (or more) dependent cỉause(s) In a complex sentence, one idea is generally more important than the other One The more important idea is placed in the independent clause, and the less important idea is placed in the dependent clause There are three kinds o f dependent clauses: adverb, adjective, and noun The follow ing chart presents an overvievv o f them You vviỉl study all o f these kinds o f clauses in greater detaiỉ in Chapters 11,12 and 13 DEPENDENT CLAƯSES ADVERBSCLAUSES A dependent adverb clause begins Nvith an adverbiaỉ subordinator such as when, while, because, although if, so that etc Although women in the United States could own property, they could not vote until 1920 In the United States, women could not vote untiỉ 1920 although they could own property Notice that there are two possible positions for an adverb clause: beíore or after the inđependent cỉause I f it comes beíore the independent clause, it is foỉỉowed by a comma (sentence 1) I f it comes after the independent clause, no comma is used (sentence 2) ' weld: join metaỉ by applying heat " fetus: unbom baby 178 Chapter 10 Types of Sentences A D JE C T lV E C LA yS E S A dependent adjective (relative) clause begins vvith a relative pronoun such who, whom, which, whose, or that, or with a relative adverb such as where

social club meeting last month vvhen I left my country 10 _ that my college adviser recommends Compound-Compỉex Sentences A compound-complex sentence is a combination o f tvvo or more independent clauses and one (or more) dependent clauses Many combinations are possible, and their punctuation requires careful attention 1 wanted to travel after I graduated from college; hovvever, I had to go to work immediately Atter I graduated from college I wanted to travel but I had to go to work immediateỉy ỉ wanteđ to travel after I graduated from college, but I had to go to work Immediately because ị had to support my family I couldn't decide where I should work or what I should so I did nothing • Punctuate the compound part o f a compound-complex sentence like a compound sentence; that is, use a semicolon/comma combination (sentence 1), or put a comma before a coordinator joining tvvo clauses (sentences 2, 3, and 4) • Punctuate the compỉex part like a complex sentence With adverb clauses, put a comma after a dependent adverb clause (sentence 2) but not before them (sentence 3) With noun cỉauses, use no commas (sentence 4) PRACTICE Compound-Compỉex Sentences Punctuate these compound-complex sentences STEP Underline the independent cỉauses vvith a solid line and the dependent clauses vvith a broken line STEP Add commas and/ or semicoỉons as necessary I f housework and chiỉdcare are

time for leisure activities rather than for housevvork or childcare Contpound Sentences (Coordination) versus Compíex Sentences (Subordination) Good vvriting requires a mixture o f all four kinds o f sentences: simple, compound, complex, and compound-complex A composition vvith only short, simple sentences is boring and inefĩective, as is vvriting that uses too many compound sentences W rỉting vvith complex sentences and participial phrases’, structures that use subordination, is General ly considered more mature, interesting, and effective in styíe Compare the tvvo models that follow The ĩirst model is an exampỉe o f overcoordination, or vvriting with too many compound sentences In the second modeỉ, some o f the coordinalỉon has been replaced by subordination-compỉex sentences in sentences 5, 6, 7, 9,11 and 12 and participial phrases in sentences and 10 Notice, hovvever, that coordination has been preserved vvhere the ideas expressed are equal (sentences 1,4 and 8) IVIODEL

all over the world because of*her beauty, her compassion for others and her style PRACTICE9 Subordination Change the foỉlowing compound sentences to complex sentences by subordimating one o f the clauses Use the subordinator given Note: Be sure to add the subordinaitor to the correct clause so that the resulting sentence is ỉogical Example It vvas raining, so I took an umbrelỉa to work (because) Not logical: It vvas raining because I took an umbrella to vvork Logical: took an umbrella to vvork because it was raíning In the fom ier Soviet Union, men and vvomen had access to equal

vvords ^One example of nonverbal communication is what occurs betvveen parents and child ^parents smile at their child ^hey communicate love, acceptance, and reassurance ^The child feels comíortable and safe ®The smiie signifies approval ^ h e child is happy and well-adjusted ^°Another exampỉe of such communication is the ỉmage a person projects in public woman is vvalking alone on an unfamiliar

independent clausc • expresses a complete thought English grammar is easy • can be a sentence by itse!f A dependent cỉause • becins vvith a subordinator Adverb: because grammar is easy • cannot be a sentence by itself Adjective: vvhich is in Spanish • is one o f three types: adverb, adjective, or roun Noun: that grammar is easy 183 Part 111 Sentence Structure There are four kinds o f sentences in English: simple, compoiind, complex, and compound-complex Each kind is punctuated differently A simple sentence has one M J T independent clause r, Englislì Qrammar is easy o J A compoiind sentence

that grammar is easy A compound-complex sentence Because grammar is easy, I learned it quickly, biit has tvvo indepenđent clauses and it took me several years to master' vvriting one (or more) dependent clauses Allhough good vvriters use all four kinds o f sentences, the use o f subordination (complex and compound-complex sentences) is considered a more mature, interesting, and effective \vriting síyle Paralleỉism Parallelism is an important element in English \vriting, especially vvhen yoii are Ịisting and comparing and contrasting items or ideas Parallelism means thai each item in a
