any other places thanWhereas/while/like/unlike的互換比較（comparison）1. 比較：(1) whereas = while（while前后句子之結(jié)構(gòu)要求并列相對）(2) whereas連接的平行比較只要求對比的核心邏輯上有對稱關(guān)系，不要求對稱位置必須是對稱名詞，下面句子中主從句的主語分別是energy和nuclear power并不是對稱名詞，但是對比的核心都是“核能發(fā)電占總產(chǎn)出能量的份額”：標(biāo)準(zhǔn)書面語中，like/unlike后只加名詞(不一定具體名詞)表比較，不能加不定式短語,分詞短語(prep 1-54 unlike cooking with speices錯),句子或介短。（后面接這些東西的時候unlike要改為whereas等等）。(4) like/unlike是嚴(yán)格的硬梆梆比較，比較對象必須嚴(yán)格對等，中間不能插入任何成分比如介詞短語As & than 的省略1. as+adj/adv+as或more than固定搭配：as或than引導(dǎo)比較從句中的省略原則-from 白勇語法1) 比較從句謂語與主句謂語相同，可用do，did，does代替。2) 比較從句連系動詞be與主句連系動詞be相同，可以省略be，也可以不省略。3) 主語謂語動詞短語使用“助動詞（如have，has，had，will）或情態(tài)動詞（can，could，may，should）+verb”形式時，比較從句往往省略verb，保留助動詞或情態(tài)動詞。4) 比較從句的主語和謂語與主句的主語和謂語相同時，可以全部省去，常常保留做狀語的介詞短語或狀語從句。5) 比較從句的主語與主句主語相同，可以省略。A is more * than B 比較比較-主語比較 1.（1）對主謂賓全的句型主語比較：A do sth than B do.（AB為對等名詞，加do是為了顯示這是一個可以發(fā)出動作的名詞，因而確定是主語，進(jìn)而確定是主語對比）。時態(tài)要據(jù)后定。There be 句型等同于一般的主謂賓俱全的句型。 （2）主語相同，狀語的比較主語若相同，可省，但助動詞不能省。如： As a result of the continuing decline in the birth rate, fewer people will enter the labor force in the 1980s than (few people省略)did in the 1960s and 1970s, a twenty-year period during which people born after the war swelled the ranks of workers. 2.對只有主謂，沒有賓語的句子，因為沒有賓語，只可能有主語比較，因而不需要重復(fù)do來確認(rèn)這是一個可發(fā)出動作的主語，所以其比較形式如下（如果主語有定語成分，必須要that/those來指代）： I eat faster than you.注意與下句區(qū)別 I eat apple faster than you do 如果寫成 I eat apple faster than you 按GMAC的理解，從語法上就變成我吃蘋果比吃你快，成了賓語比較。邏輯上顯然不通。 3.主系表結(jié)構(gòu)的比較與主謂結(jié)構(gòu)相同。如果時態(tài)不一致，則需補(bǔ)出助詞，如： The economy of Florida is more diversified than it was ten years ago Just as A do, so B dojust as A do, so B do平行比較結(jié)構(gòu)的習(xí)慣搭配：意思是：就如同AB*: 這里的as是不能用like,whereas的。而且likeso不符合搭配習(xí)慣，應(yīng)該去掉so*: just as with和just like都是很wordy的2. 下面三種形式無區(qū)別（后兩種強(qiáng)烈語氣，不可以隨意刪掉so）前后都要用句子，不能只用短語。Just as , so Just as you sow, so you will reap 主從句要盡量形式對稱Just as , as Just as you sow, as you will reap 主從句要盡量形式對稱Just as , so too 主句要部分倒裝(so too后是主句) Just as you sow, so too will you reap so with是錯誤結(jié)構(gòu)。(prep 1-15)l as with的結(jié)構(gòu)在日常語法中是對的(意思為“正如的情況一樣”， 看作是as is the same with的省略式，with 后面常跟名詞、動名詞或what從句)：倍數(shù)表達(dá)法一、倍數(shù)表達(dá)法1、twice的用法：twice as manyas; twice as muchas; twice + n.(可以是代詞，比如that); twice + what從句; *：一個大家常誤會的句子：The farm has more than twice as many cows as it has pigs.: 農(nóng)場有多于豬兩倍多的牛的數(shù)量（農(nóng)場牛的數(shù)量比豬的兩倍還要多）。（很多人會誤讀為豬比牛多。）解讀方法：可以類比一下A has B twice as many as C這個比較句型也可以寫為A has twice as many B as C. 所以句子的核心是A has B，即：The farm has cows. 詳細(xì)解讀：twice as as中前一個as是副詞，more than twice as修飾many；而as it has pigs中的as自然是個連詞，所以后面跟的是一個adverbial clause（狀語從句/副詞從句），而asas句型比較特殊，后面的as要與前面as所修飾的內(nèi)容相呼應(yīng)，所以as it has pigs應(yīng)該與前面as所修飾的對象many相呼應(yīng)，即as it has pigs也是修飾了many。不管怎么說as it has pigs都不是核心成分。這樣翻譯過來就是農(nóng)場有牛，相當(dāng)于兩倍多的豬。故，牛多豬少。2、用動詞表達(dá)倍數(shù)：double/triple/quadruple/quintuple/sextuple -這些動詞可以做形容詞(double還能做adv, predeterminer)sth. double sth.; sth. is doubled; sth. double(adj.);幾個永遠(yuǎn)錯誤的形式：(1)produce double； a doubling of; produce a doubling(2)as much as twice the apples(much與apples矛盾)（要改為twice as many apples as; sth. double sth.）*：這幾個動詞可以用主動也可以用被動，但是不能和as搭配;（差不多記住這句話就可以）3、times(或數(shù)字) as + 形容詞或副詞+as;4、sb. be + 百分?jǐn)?shù) + more likely (to do sth.) than to do sth.(前面的to do 能省，后面的不能省) 如：at least fifty percent less likely than those who are sedentary to die of a heart attack5、表達(dá)倍數(shù)用“ times + more +adj.+than， time as +adj.+as”都正確6、三類表示倍數(shù)的形容詞為：twofold, threefold, fourfold, tenfold等。以twofold為例，其意思為two times as much or as many of something。該類詞為形容詞，多用于構(gòu)成形容詞名詞的詞組，如：a threefold increase in revenue，少用于比較兩個事物之間的倍數(shù)關(guān)系。二、章振邦語法中介紹的倍數(shù)表達(dá)法：i. x times(twice) + the + n. (twice還能做determiner)ii. x times adj. (比較形式) thaniii. x times as adj. as 注意里面的adj.要和前面的名詞匹配A do x times as adj. x as B do iv. x times + what 分句 (名詞性從句相當(dāng)于名詞)v. x-foldvi. double, triple, quadruple, quintuple, sextupleTimes 作比較時的用法1. times做比較時的用法1）X times+as+adij./adv.+as2）X times+the+n.3）X times more thanTwicetwice只能作副詞, 在句子中表達(dá)的意思卻是比較, 這樣的題目, 首先要弄清楚比較的雙方是否合理, 如果合理的話, 再看twice作為副詞的位置: 可以用在as.as或比較級之前, 也可以放在比較點(diǎn)的名詞之前, 擔(dān)要保證twice前后的詞要能直接搭配(副詞的作用).eg: He is twice the man he was. = He has twice the strength he had =He is twice as strong as he was.Twice as many/much as 結(jié)構(gòu)1. 關(guān)于twice as many/much as結(jié)構(gòu)：2. If you say twice asmany, then this construction should be paired with acountable noun.e.g.,twice as many dogs- dogs is a countable noun3. If you said twice asmuch, then this construction should be paired with anuncountable noun.e.g.,twice as much water- water is an uncountable noun4. If the noun in question is already anexplicitly numerical quantity, then you should useneithermuch nor many. Instead, you should just use twice or double by itself.e.g.,twice the increase- increase is an explicitly numerical quantity5. These rules are followed pretty closely.so, for instance:twice as much water- correct, since water is an uncountable noun (but is not an explicitly numerical quantity)twice the water.- incorrect, since water is not a numerical quantitytwice as much as the increase.- incorrect; redundanttwice the increase.- correct類似just as 的結(jié)構(gòu)what = just as,意為“恰像，猶如，好比”用作連詞,引導(dǎo)比較狀語從句(1) 慣用句式是：A is to B what C is to D. 意為“A對B而言正如C對D一樣”例如：Air is to us What water is to fish. 空氣對于我們猶如水對于魚。(介詞to表示兩者的關(guān)系) (2)也有“A is for B what C is for D.”句式。例如：Poultry is for the cook what canvas is for the paint. 廚師離不了家禽正如畫家離不開畫布一樣。（介詞for表示“供使用”）(3)what 引導(dǎo)的從句也可以放在句首,其句式是: What C is to D, that A is to B.(= A is to B what C is to D.) 在這一結(jié)構(gòu)中，喻體在前，主體在后，相當(dāng)于“just as.,so.”結(jié)構(gòu),意思也是“A對B而言正如C對D一樣”例如:What blood vessel is to a mans body, that railway is to transportation.（=Just as blood vessel is to a mans body, so Railway is to transportation.）鐵路對于運(yùn)輸,好比血管對于人體一樣。(4)需要注意的是what不可以直接被just as替換，just as需要有遵循屬于自己的平行比較格式。比較之庖丁解牛對主謂賓全的句型主語比較： A do sth than B do.（AB為對等名詞，加do是為了顯示這是一個可以發(fā)出動作的名詞，因而確定是主語，進(jìn)而確定是主語對比）介賓比較： A do sth of C1 by D1 than of C2 by D2.（C1C2，D1D2對等名詞）賓語比較： A do C1 than C2.(C1C2為對等名詞）狀語比較： A do sth than usual/everbefore/people expected(直接加狀語）ETS就這幾下子，原則就是清楚地指示什么跟什么比。按照這個原理，對下一種句型只有主謂，沒有賓語的句子，因為沒有賓語，只可能有主語比較，因而不需要重復(fù)do來確認(rèn)這是一個可發(fā)出動作的主語，所以其比較形式如下：I eat faster than you.注意與下句區(qū)別I eat apple faster than you do如果寫成 I eat apple faster than you 按ETS的理解，從語法上就變成我吃蘋果比吃你快，成了賓語比較。邏輯上顯然不通。AS族的比較大同小異，as 可單獨(dú)引導(dǎo)比較，也可以復(fù)合成as many as, as hard as 等形式，但ETS宗旨不變，如Sand road costs twice as many to build as to manintain(類似于介賓比較）Sand road costs twice as many to build as stone road do(主語比較,）Sand road costs the govement twice as many to build as the residents.(賓語比較）ETS考過AS比較的習(xí)慣用法（不受上述限制，如下）AS poor as they are, they can not afford a car.They have 800million students, as many as have enrolled in our school.(注意以上都是用逗號隔開的句子，AS在這里的作用更類似連詞，連接一個主句和一個從句）注意AS有時不表比較的如as you work hard, you will pass the exam.表原因了。There be 句型等同于一般的主謂賓俱全的句型OG89There is one PC for every 32 pupils in American four time as many as there were four years ago(主語比較)There is one PC for every 32 pupils in American four time as many as DVD player(賓語比較)There is one PC for every 32 pupils in American four time as many as for school teachers.(介賓比較)There is one PC for every 32 pupils in American four time as many as in china(介賓比較)以上的綱領(lǐng)代入EST的OG幾乎都成立，在我這次實(shí)戰(zhàn)中也成立，但GWD中有一題是例外的，也就是說并沒有放之四海而皆準(zhǔn)的真理，清楚，簡潔，合理才是ETS的最高宗旨。依然比較，大愛比較1. whereas/while這種連詞連接的比較成分不要求含義上絕對的平行，具體見prep 1-211。3. 1) compared with直接跟在逗號后面可以修飾逗號前面名詞短語的核心詞：Example： In the United States, while the number of foreign-born residents and their children is higher than ever, the percentage of the population they represent is not; in 1910 this group made up 35 percent of the population, compared with 20 percent in 2000.2) Compared with也可以修飾前面整個分句，compared with后面的名詞與主語比較：Example:u Today, more than 43 percent of Californians under the age of eighteen are Hispanic, compared with about 35 percent a decade ago.u In the United States, Fifty-two percent of high school graduates go on to college, compared with thirty-five percent in Canada and fifteen percent in Great Britain, Japan, and West Germany.u One baby in four is now born to a mother aged thirty or older, compared with just one in six in 1975. 3) as compared to/with中as指代前面整句的核心含義：A recent review of pay scales indicates that, on average, CEOs now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio in 1980.As. As 中間加名詞 as adj. a noun. as as.as之間是可以加 adj+noun的，不過好像只限于幾種形式(張振邦)：as+adj.+不定冠詞+單數(shù)可數(shù)+as I havent seen as old a car as this for years.as+adj.+零冠詞+不可數(shù)名詞+as 對應(yīng) prep2-9 (見類似題鏈接)as+adj.+零冠詞+復(fù)數(shù)可數(shù)名詞+as I dont smoke as expenesive cigarettes as those.2. as adj. (a) noun. as = (a) noun. as adj. as，其中第一個as是adv.比較結(jié)構(gòu)的指代1. 比較句要求比較對象對等，邏輯含義合理，且句子沒有歧義。 2. 關(guān)于指代：前面是單數(shù)名詞，后面如果要指代，只能用that，如果需要表達(dá)復(fù)數(shù)意思，那么只能重復(fù)這一名詞的復(fù)數(shù)形式，如economy-economies,不能隨意改成those, ets視之為指代錯誤。(1)單數(shù)名詞- that/該名詞復(fù)數(shù)形式(2)復(fù)數(shù)名詞- those比較結(jié)構(gòu)省略（把后面的知識點(diǎn)看懂，說明你挺不錯）1. 一道類似卻不一樣的題 - 未完稿：OG10-19. In addition to having more protein than wheat does, the protein in rice is higher quality than that in wheat, with more of the amino acids essential to the human diet.(A) the protein in rice is higher quality than that in(B) rice has protein of higher quality than that in(C) the protein in rice is higher in quality than it is in(D) rice protein is higher in quality than it is in (E) rice has a protein higher in quality thanIn this sentence, the initial clause modifies the nearest noun, identifying it as the thing being compared with wheat. By making protein the noun modified, choices A, C, and D illogically compare wheat with protein(是指In addition to having more protein than wheat does這個從句里面) and claim that the protein in rice has more protein than wheat does. In C and D, the comparative structure higher in quality than it is in wheat absurdly suggests that rice protein contains wheat. B, the best choice, logically compares wheat to rice by placing the noun rice immediately after the initial clause. B also uses that to refer to protein in making the comparison between the proteins of rice and wheat. Choice E needs either that in or does after wheat to make a complete and logical comparison. 從E可以看出，用than that in wheat或than does wheat都可以，但這并不能說明在其他的比較結(jié)構(gòu)中也能用that in，而不是用主謂(賓)結(jié)構(gòu)來與than前面的結(jié)構(gòu)平行。在這個句子里：Only seven people this century have been killed by the great white shark, the man-eater of the moviesfewer than have been killed by bee stings.后面的比較成分是不可以改為less than those killed by bee stings的。具體原因如下：在rice has a protein higher in quality than that in wheat這個句子里，比較對象是protein和that（that指代的也是protein），比較的僅僅是protein（rice has不在比較成分之內(nèi)，比較的是protein的屬性），所以允許平行。而在Only seven people this century have been killed by the great white shark, the man-eater of the moviesfewer than 中， 不僅僅Only seven people，后面的this century have been killed by the great white shark也都在比較對象里面，所以后文不能用those killed by bee stings，而應(yīng)該用平行的結(jié)構(gòu)than have been killed。再比如這個句子(GWD-29-24)：According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than (that of) livestock fed on grain and more of a kind of fat thought to be good for cardiac health. 這個句子不對。其在livestock前加上that of比較的對象是animals has less fat和that，that指代fat，而事實(shí)上比較的應(yīng)該是wild animals和livestock的屬性，即擁有fat的多少，所以than后面也應(yīng)該用平行的句式，即主謂賓形式。正確句子為：According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be good for cardiac health.。要注意的一點(diǎn)：在此省略了相同的謂語和賓語（因為不會有wild animals have livestock的歧義，只要邏輯上基本成立，GMAT并不認(rèn)為所有沒有補(bǔ)出謂語動詞的形式都是”ambiguities”的）。（原句不對的另外一個證據(jù)： more of a kind of fat 后面省略了(than)，而省略的部分應(yīng)該和less total fat than后面的詞句是一致的，這樣才能省略邏輯上看省略的必須是livestock，而不能是that of livestock，因此less total fat than后面跟的也應(yīng)該是livestock。）二時態(tài)n 注意句子中的現(xiàn)在完成與現(xiàn)在進(jìn)行共存的情況，很可能被判時態(tài)矛盾n 注意：如果句中有兩個事物的對比，句中出現(xiàn)他們是simultaneously 或者是the same time什么的，則要注意其中一句如果用完成時會與“同時”相矛盾。以下情況用現(xiàn)在完成時：n within/during/in/over+ the past/recent/last+時間段(注意during/in/over the last year可以用現(xiàn)在時也可以用完成時，取決于當(dāng)時發(fā)生的事情是否延續(xù)到現(xiàn)在或?qū)ΜF(xiàn)在是否還有影響，而last year用過去時)ll 出現(xiàn)since考慮現(xiàn)在完成時以下情況用一般過去式：l 出現(xiàn)original/originally, firstl 過去明確時間l 過去段時間以下情況用一般現(xiàn)在時l 自然現(xiàn)象l 統(tǒng)計數(shù)據(jù)l 實(shí)驗結(jié)論l 客觀事實(shí)將來時：i. 條件從句/時間從句/方式從句/讓步從句不能用將來時或過去將來時，常用一般現(xiàn)在時代替一般將來時，一般過去時代替過去將來時。（對比狀從省略的幾種是：轉(zhuǎn)折，時間，條件。）ii. possibility that/likelihood that/expect that中,that從句后用一般將來時iii. 標(biāo)準(zhǔn)書面語中,優(yōu)先使用一般將來時,主觀將來時用be supposed to do,較少用be going to do,不用be to be doing/be to be done一般時與進(jìn)行時過去進(jìn)行時與一般過去時的對比： 過去進(jìn)行時與一般過去時，兩者都表示過去發(fā)生的動作,但過去進(jìn)行時表示在過去某一特定的時間點(diǎn)或時間段正在進(jìn)行的動作,而一般過去時表示在過去時間完成的動作例如: I was typing a letter last night. 昨晚我在打一封信(可能沒打完) I typed some letters last night. 我昨晚打了一些信(已經(jīng)打完) 4. 現(xiàn)在完成時時與一般現(xiàn)在時： yield用現(xiàn)在完成時與一般現(xiàn)在時都說得通，但是含義不一樣，用have yield說明了the first trenches是過去發(fā)現(xiàn)的，至今仍能提供證據(jù)，而yield的話則是說明是現(xiàn)在發(fā)現(xiàn)的，所以用have yield更合理三指代Which Which指代小結(jié)by aeoluseros：以下收錄官方材料中能對于which的使用，可以發(fā)現(xiàn)which的指代其實(shí)并沒有固定死規(guī)則，不一定只指代最近的名詞，跟所有代詞一樣，有就近指代的的傾向，但是具體修飾對象，應(yīng)該根據(jù)各種線索或者邏輯含義來判斷：1. 盡管A of B的結(jié)構(gòu)，which沒有就近修飾。561.One pervasive theory explains the introduction of breakfast cereals in the early 1900s as a result of the growing number of automobiles, which led to a decline in horse ownership and a subsequent grain glut; by persuading people to eat what had previously been horse feed, market equilibrium was restored.2. which不一定跳過插入語指代：462.Judge Lois Forers study asks why some litigants have a preferred status over others in the use of a public resource, the courts, which in theory are available to all but in fact are unequally distributed between rich and poor.3. 通過單復(fù)數(shù)判斷which的所指：80.Changes in sea level result not only from changes in water temperature, which affect water density, but also from the melting of glaciers.44.The survival of coral colonies, which are composed of innumerable tiny polyps living in a symbiotic relationship with brilliantly colored algae, is being threatened, experts say, not only by pollutants such as agricultural runoff, oil slicks, and trash, but also by dropped anchors, probing divers, and global warming.173 (GWD-10-Q18) In analyzing campaign expenditures, the media have focused on the high costs and low ethics of campaign finance, but they have generally overlooked the cost of actually administering elections, which includes facilities, transport, printing, staffing, and technology.205.
