Arctic oil may be worth drilling for, if wells can be dug there and environmental concernsaddressed.（2）itself, themselves, one another, each other: 一般表強(qiáng)調(diào)其指代的名詞After the agreement surfaced, the mission dissolved it. (解散Agreement)After the agreement surfaced, the mission dissolved itself. (解散Commission)（3）such, other, another以上三個代詞一般在后面跟一個概括性的名詞指代前面的名詞。After the agreement surfaced, the mission decided to subject any such contracts to debate inthe future.（4）one：指代具有非定義性，且只能指代前面的單數(shù)名詞，或者其中的一個。After walking by the chocolates so many times, Roger finally had to eat After walking by the chocolates so many times, Roger finally had to eat （5）do so 和 do itDo so : 可以指代整個的動作，包含謂語動詞，賓語和修飾語Q did not eat dinner quickly, but her brother did so. 指代eat dinner quickly（so可省略）Do it : it必須指代一個確切的名詞Q failed to do the homework, but his brother did it. 指代前面的homework.Quinn did not eat the soup, but her brother ate it.2．代詞變換位置（1）不定式做主語時，通常用it作形式主語It is futile to resist temptation. 對 TO RESIST temptation is futile. 錯（2）that 從句做主語，通常用it作形式主語It gave us encouragement that we scored at all. 223。 THAT we scored at all gave us encouragement.但是it在其他情況下都不可以指代從句。（3）不定式或that 從句做賓語，用it作形式賓語She made it possible for us to attend the movie.She made possible our attendance at the movie.She made our attendance at the movie possible. 都對3．有時候避免代詞指代不清的一種方式就是用一個概括性的名詞替代，這樣還可以避免直接用之前的名詞造成重復(fù)After roasting the deer, the hunter extinguished the fire and then searched for a tree to hang the deer(the meat) from.Right: New nanopapers incorporate fibers that give THESE MATERIALS strength.4．代詞使用的一些細(xì)微差別（1）單數(shù)代詞指代單數(shù)名詞（2）性別代詞要一致,his/her/its（3）重復(fù)的代詞經(jīng)常被認(rèn)為指代的是同一個名詞,一個句子中所有的it/they始終指代同一個詞（4）代詞一般指代離其最近的名詞，但不能過于近了；EG: In the station house IT is considered taboo. it 不能指代station house大多數(shù)情況被指代詞在代詞之前,但也有特殊的，在其之后EG: After he dried his tears, Jack made a smile.（5）代詞出現(xiàn)的平行位置（主謂賓）相同，可視為相同指代Note: 如果發(fā)現(xiàn)用以上代詞指代的5原則竟然排除了所有5個選項(xiàng)，那么只能放棄這5原則，然后找找看其他的錯誤。（二）修飾語1．of 修飾短語: of 短語修飾其前面的名詞,而代詞則指代整個of介詞短語的內(nèi)容（1）He had a way of dodging opponents that impressed the scouts.在本句中，that從句指代a way of dodging opponents，且that省略了更好，而不是單指a wayBest: His way OF DODGING OPPONENTS impressed the scouts.（2）An ice sheet covers 80 percent of the surface of Greenland, an area roughly the size of Alaska.2．為避免主語修飾語過于冗長，有時候會將修飾語后置對：A new CEO has been hired who will transform the pany by decentralizing authority to various division heads while increasing their accountability through the use of public scorecards.錯：A new CEO who will transform the pany by decentralizing authority to various division heads while increasing their accountability through the use of public scorecards has been hired.3．插入語，在主語和謂語之間，插入一個成分對主語進(jìn)行進(jìn)一步說明,用逗號隔開。Our system of Presidential elections favors states, such as Delaware, that bv population are overrepresented in the Electoral College. （that修飾的是states）4．平行修飾的時候，其中一組修飾詞一定緊跟著他們所修飾的名詞。In heraldry, the term tincture refers to a color emblazoned on a coat of arms and labeled with a special French word.總之，名詞修飾語一定要緊跟其修飾的對象，少數(shù)情況例外。（三）所有格(1) 不要選擇Y of X’s 這樣的結(jié)構(gòu)，永遠(yuǎn)是錯的； 要么of X,要么X’s(2) GMAT 在80%~90%情況下認(rèn)為復(fù)數(shù)不能用所有格，如humans’EG: : Certain humans39。 parasites have been shown to provide bacterial resistance and protection√: Certain parasites in humans have been shown to provide bacterial resistance andprotection大部分名詞用of X 結(jié)構(gòu)可以清晰替代所有格，少部分如sales,要用in所有格，不等同于普通名詞，不能簡單修飾（四）當(dāng)修飾一個集合名詞的時候，有三種常見修飾(1) This model explains all known subatomic particles, some of which were only recentlydiscovered.錯: This model explains all known subatomic particles, of which some were only recentlydiscovered.(2) This model explains all known subatomic particles, some of them only recently discovered.錯：This model explains all known subatomic particles, some of them which were only recentlydiscovered.(3) This model explains all known subatomic particles, some only recently discovered.錯：This model explains all known subatomic particles, SOME OF WHICH only recently discovered.其中的some，可能被替換成any, none, all, more/most，many, each, either, neither, half, one（五）從句與現(xiàn)在分詞修飾(1) 從句和分詞都可以修飾主語或者謂語，一般情況下可以通用，但遇到一些有明顯時態(tài)變化的句子，要根據(jù)具體情況而定。① The rate of language extinction is accelerating, a tendency ultimately culminating in thesurvival of just a few languages, according to some.② The rate of language extinction is accelerating, a tendency that will ultimately culminate in the survival of just a few languages, according to some.（這種句式又叫獨(dú)立詞組）第二句好一些，因?yàn)楦鶕?jù)ultimately用將來時要好些。而第一句表明是現(xiàn)在時。在一道題里，如果只有分詞ing的形式不同，那么通常從句＋動詞的形式分詞ing形式，因?yàn)榭梢愿逦谋磉_(dá)時態(tài)的變化。(2) 實(shí)際上有兩種修飾前句的方法① 獨(dú)立詞組：如上述形式，一般是一句結(jié)束后，一個概括性名詞+that 從句② Ving 形式：Ving 形式跟在主句后面，有四個情況可用：；；（在主系表結(jié)構(gòu)中），例如bring to 34只海鳥那道題。Scientists have found high levels of iridium in certain geological formations around theworld, suggesting the cataclysmic impact of a meteor millions of years ago.（suggesting修飾de是前面整句話，那個發(fā)現(xiàn)結(jié)果）CH13動詞和比較（高階）（一）助動詞：be /do /have1．若出現(xiàn)時態(tài)變化，則句子中助動詞不能單獨(dú)的使用對I have never seen an aardvark, but my father has.錯I have never seen an aardvark, but last year my father did.對I have never seen an aardvark, but last year my father saw 2．助動詞后省略的詞一定要是原文之前出現(xiàn)過的錯Our cars were designe
