SAT語(yǔ)法知識點(diǎn)簡(jiǎn)析八則
1.名詞(包括代詞)。單復數問(wèn)題。
判斷方法：對比主語(yǔ)跟賓語(yǔ)。主語(yǔ)跟賓語(yǔ)的單復數形式必須相同。也可能會(huì )根據謂語(yǔ)或者定語(yǔ)進(jìn)行判斷。下面是例題。
No matter when they came from or what their previous lifestyle is, the refugees were grateful for having been granted political asylum in the United States. No error.
請看what their previous lifestyle is這段話(huà)， their跟lifestyle的單復數不同，當然還有后面的is也一起錯了。應該改成lifestyles are.
2.動(dòng)詞。主謂一致的單復數問(wèn)題。時(shí)態(tài)錯誤。過(guò)去式的單詞錯誤。時(shí)態(tài)錯誤主要發(fā)生在主句和從句的時(shí)態(tài)不一致。詞匯錯誤就是有些不規則動(dòng)詞的過(guò)去式用錯，比如常見(jiàn)的hang、rise等等，當然也有drove寫(xiě)成drived的。
判斷方法：看到動(dòng)詞，要本能的反應是單復數、時(shí)態(tài)問(wèn)題，如果都沒(méi)有就考慮詞匯用錯問(wèn)題。
注意：CB那班賤人很喜歡使用倒裝來(lái)迷惑眾生。
Air pollution caused by the industrial fumes has been studied for years, but only recently has the harmful effects of noise pollution become known. No error.
這里面only recently has the harmful effects of noise pollution become known使用了倒裝。The harmful effects是主語(yǔ)，has是謂語(yǔ)，所以現在答案很明顯了吧。
語(yǔ)法補習：
Neither…or…; Either… or…后面的謂語(yǔ)跟第二個(gè)主語(yǔ)保持一致。
…along with…; …as well as…; …in addition to…與第一個(gè)主語(yǔ)保持一致。
Both…and…就不說(shuō)了，用復數形態(tài)。
3.固定搭配。動(dòng)詞與介詞，比如look at。連詞搭配，比如either…or…
判斷方法：看到有介詞劃線(xiàn)就注意一下。這種題目平時(shí)積累很重要!
背固定搭配的時(shí)候一定要注意介詞與不定式的區分問(wèn)題!比如look forward to，to是介詞，后面的動(dòng)詞要使用動(dòng)名詞形式。
4.代詞。主格與賓格。指代不明。文中出現的多個(gè)代詞不一致。
判斷方法：代詞是用來(lái)指代的�？吹酱~馬上回頭尋找其指代對象。
To become a world figure-skating champion like Kristi Yamaguchi, one must be so dedicated that you will practice six hours a day. No error.
這句話(huà)的問(wèn)題在于代詞使用不一致。請看one must be so dedicated that you will practice six hours a day，前面用的代詞是one，但是后文使用的是you，再理解句意，不難發(fā)現兩個(gè)代詞其實(shí)是在指代同一個(gè)人。所以應該把you改成one.
5.平行并列結構。兩個(gè)以上的分句并列時(shí)，一般美國人愛(ài)用并列結構，這樣的好處是使文章看起來(lái)工整。
判斷方法：出現多個(gè)并列成分;出現比如from…to…等類(lèi)似的經(jīng)典介詞組合。注意：并列結構使SAT很喜歡考察的內容!
Each time Caroline turns on her computer, she has to enter a company code, then her initials, and then enters a password before she can begin working. No error.
讀句子，發(fā)現這個(gè)女人工作之前要干3件事：enter a company code, enters her initials, enters a password，這3個(gè)動(dòng)作構成了并列。題干已經(jīng)有提示：she has to enter a company code, then (enters)her initials, 所以剩下來(lái)的enters毫無(wú)疑問(wèn)也應該省略即改成and then(enters)a password before she can begin working
A talented and versatile artist, Twyla Tharp has been a dancer, choreographer, and collaborated on various productions. No error.
還是并列結構，改成has been a dancer, choreographer, and collaborator.這樣的句子就很整潔了。寫(xiě)作的時(shí)候可以用上的。
6.形容詞與副詞混淆。判斷：看到以后注意就行了。
Although the new device was the most clever designed bird feeder that Ms. Rodriguez had ever owned, it could not keep squirrels from stealing the birdseed. No error.
用Word一看就知道哪里有錯了……clever designed里頭，designed是動(dòng)詞，clever是修飾designed的。但是修飾動(dòng)詞的只有副詞，所以毫無(wú)疑問(wèn)要將clever改成cleverly.
7.邏輯。雙重否定。
8.同級比較。比如My pen in more beautiful than you. Pen跟you并不是同一類(lèi)事物。
