上期帶來了SAT文法知識點，新航道上海學校SAT培訓班小編繼續給大家帶來SAT文法第二期，每期分享3-5個文法知識點，幫助大家更好地備考SAT。

  一、動詞

  主謂一致

  1. 含義：

  主語和謂語的單復數一致，比如主語是復數，謂語動詞必須是復數，要保持一致。

  例如：Students are taking the test right now.

  2. 用法：

  (4) 定語從句的主謂一致

  (5) 倒裝結構

  (6) 就近原則

  上期鏈接：SAT備考 | SAT文法知識點第1期

  (4) 定語從句的主謂一致

  a) 定義：

  i. 定語從句中關系代詞作主語時，謂語動詞的單復數由先行詞決定

  b) 例句

  例句1：Thanks to the strength of the bonds between its constituent carbon atoms, a diamond has exceptional physical properties that make it useful in a wide variety of industrial applications.

  解釋：that從句的make由先行詞that決定，that指代前面的physical properties。

  c) 真題檢測

  (2018-03AS-Q29) Physicians focus on diagnosis and pharmacists focus on drug therapies, a division of labor that was cost effective and helpful for patients.

  A. NO CHANGE

  B. is

  C. had been

  D. would be

  解析：通過前面的語態focus on看出是一般現在時，所以排除A/C/D三個選項，所以選B。

  注：2018-03AS-Q29為2018年3月亞太真題29題。

  (5) 倒裝結構

  a) 定義

  將謂語的一部分或全部置于主語之前的語序叫做倒裝語序。

  b) 類型

  完全倒裝：將整個謂語提到主語之前;

  部分倒裝：只將be動詞、情態動詞或者助動詞放在主語之前。

  c) 例句

  例句1: In the back of the textbook are a list of words that can be easily learned by those who want to improve their command of English.

  解析：in the back of the textbook為地點狀語，are是謂語動詞，a list of words+that從句是真正的主語，該句的are在主語前，為全部倒裝結構。

  例句2: What becomes apparent from assessing scientific accomplishments is that only relatively recently has the necessary technology been developed for solving the mysteries of genetics.

  解析：that從句中the necessary technology是真正的主語，has been developed是謂語動詞，只有助動詞has在主語前，為部分倒裝結構。

  d) 真題檢測

  (2016-11AS-Q34) Less well known were Nightingale’s promotion of statistical analysis in the field of medicine, even though this work may have been more important to the development of modern health policy.

  A. NO CHANGE

  B. are

  C. is

  D. had been

  解析：謂語動詞之前的less well known不能作主語，所以該句是倒裝句，真正的主語是Nightingale’s promotion，是單數，所以排除A/B/D, 所以選C。

  注：2016-11AS-Q34為2016年11月亞太真題34題。

  (6) 就近原則

  a) 定義

  由下列詞語連接的并列主語："there be+句型; or ; either …or;nor; neither…nor;whether…or;not…but; not only…but also”; a, b or c 等，謂語動詞可與后面第一個主語一致。

  b) 例句

  ①What he does or what he says does not concern me.

  ②Neither you nor I am wrong.

  ③Not you but your father is to blame.

  ④Not only you but(also) he is wrong.

  解析：1-4的例句中or或nor后的謂語動詞與第一個主語動詞一致，what he says/ I/ your father/ he都是單數，所以4個例句中的謂語動詞也是單數。

  c) 真題檢測

  What Tom said or what Mary said were the best possible solution for this program.

  A. NO CHANGE

  B. have been

  C. had been

  D. is

  解析：根據what Tom said or what Mary said判斷，該題考察就近原則，主語為謂語動詞附近的what Mary said，是單數，所以排除A/B/C，所以選D。
