SAT语法知识点详解——平行结构

　　据留学360介绍，平行结构的知识点考察在SAT的考试中是必考的一项，然后在中国的高考中对于这个知识点却只有极少的关注度；因此造成了很多同学对于此知识点的掌握不牢固，必然会造成在SAT考试中会丢分。所以综合SAT语法考试的特点总结出以下的考点。

　　考点聚焦：

　　(1) 三者之间的平行----N, N, and N（名词，名词，and 名词）

　　据留学360介绍，此种题型就是我们常说的“名词，名词，and 名词”的形式，这三个名词是相互并列的。出题的习惯通常划线部分放在第三个，即在and 名词上面划线。

　　例句1：Each time Mary turns on her computer， she has (A) to enter a company code, then her initials, and then enters a password (B) before (C) she can begin working (D). No error (E).

　　例句2：Without the invention of the compass, Mike might not have sailed around the world, Lewis and Isaac might not have traveled to Bonn, nor might Kevin’s search for the cities of gold have occurred, either.

　　(A) nor might Kevin’s search for the cities of gold have occurred, either

　　(B) nor might Kevin search for the cities of gold

　　(C) and Kevin’s search for the cities of gold might not have taken place

　　(D) and Kevin might not search for the cities of gold

　　(E) and Kevin might not have searched for the cities of gold

　　（2）比较句：此种题型在考试当中几乎每次都可以见到，考点集中在同类比较

　　出现此题型的标志有：-er; more,than; as; like; unlike; compare to/with等

　　错误例句：The climate in Shanghai is more humid than Beijiing.

　　改为：The climate in Shanghai is more humid than that of Beijing.

　　此句中“that”表示句子开头的“the climate”

　　例句1： In (A) the United States, the industrial use of (B) plastic is (C) greater than steel (D), aluminum, and copper combined. No error (E) (OG P777 28)

　　例句2： In a recent year, more tourists from the United States visited museums in Great Britain than Canada.

　　(A) Canada

　　(B) Canada did

　　(C) compared to Canada

　　(D) Canadian ones

　　(E) in Canada

　　（3）两者之间的平行：两者之间的平行一般的几个标志如下：

　　not only……,but also….

　　neither…. nor……../ either……or……（在SAT中被视为送分题） ….. and / but…..

　　出现以上的标志词后必须做到一一对应；但以下为特殊情况：

　　如：either plan to do，or risk doing

　　（这种句型出现是正确的，句子当中的主体结构完全一一对应，“plan”和“risk”已经做到对应，后面的“to do”和“doing”只是固定用法。）

　　例句1：The labor union is negotiating (A) a contract with the hospital that (B) will satisfy (C) the demands of the workers and be acceptable to (D) all levels of management. No error (E) （OG P601 13）

　　例句2：Most drivers know not only that excessive speeding on highways wastes gasoline, but also that it is dangerous. （OG P678.13）

　　(A) know not only that excessive speeding on highways wastes

　　(B) know that excessive speeding on highways could be wasteful of

　　(C) are knowledgeable that excessive speeding on highways not only wastes

　　(D) have known that excessive speeding on highways wastes not only

　　(E) know that excessive speeding on highways not only by itself can waste

　　(4) 两个句子之间的平行

　　两个句子之间的平行，后一个句子之间用逗号加上连词隔开，或者直接用一个分号隔开

　　标志：and，but，分号等

　　例句 Driving less (A) frequently is one way to save energy; to turn off all (B) appliances when they are (C) not being used is another (D). No error (E) (OG P720 18)
