3、SAT语法题目

s pictures fell off the mantel, （having left） many of them shattered beyond repair.

我知道having left 是错误的，原因我觉得是因为“having left”在此句中修饰“all of Luissa's picture” 而且having left表示这个动作在“pictures fell off the mantel”之前发生的，所以不正确

可是书后给出的解析说：

“having left is unclear and seems to attribute the action of leaving to the pictures rather that Luissa . to be correct, the sentence should read leaving instead of having left”

疑问1：为什么having left这个动作要修饰Luissa，我觉得应该要修饰the earthquake啊，应该是earthquake使得很多照片“shattered”

疑问2：改为leaving 难道就修饰Luissa了么？岂不谬哉？！

4、SAT 语法题！！

5.Earlyrockandrollmusic,likejazzandtheblues,celebratedcharacteristicsofurbanlifethat(wasonce)onlydisparaged:loud,repetitivecitysoundswerereproducedasraucousmelodiesandinsistentrhythms

【解读】

通过句子分析判断，分析时可以剔出必要的附加成分（方括号标出）。

主句：Earlyrockandrollmusic,【likejazzandtheblues,】celebratedcharacteristicsofurbanlife早期的摇滚乐【如爵士乐和布鲁斯】表现出了城市生活的特点

定语从句：that(wasonce)【only】disparaged:反而一度被贬低的…：

从冒号后loud,repetitivecitysoundswerereproduced(喧嚣且重复的城市声音被复制出来)【asraucousmelodiesandinsistentrhythms(作为沙哑悦耳并动人的旋律)】的解释，特别是reproduce（再生/翻版/重现）的含义，可知，定语从句的关系代词指代rockandrollmusic。

6.(Asignificantfactor)toincludeinthebudgetwhen(buying)acararethecostsoffuelandmaintenanceandtheinsurancepayments.

【解读】

任何行为都会有一个执行者，非谓语动词也不例外，其执行者称作逻辑主语。有的逻辑主语通过特定的语法手段介绍出来，如forsb.todosth.，one’sdoingsth.，onedoingsth.或者bysb.，而有的则是不提自明的“人们”。本句中的buyingacar是动名词短语作主语，它的逻辑主语就是后者，整个意思是“把（人们）购买车辆的时的预算包括在内”。

本句的主要成分是(Asignificantfactor)arethecosts，可见主谓人称不一致，应该是(significantfactors)arethecosts。

7.In1988aSovieticebreakingship(helpedfree)threegraywhalesthat(hadbecometrapped)intheArcticiceafterthey(hadswam)intothecoastalwatersofAlaskatofeed.

这里答案是由hadswam改成hadswum么能分析下三个括号之间的时态联系吗？

【解读】

swam是过去式，swum是过去分词，had后只能用过去分词。

主句中的helpedfree是苏联破冰船发生在过去的行为，hadbecometrapped和hadswum都是灰鲸发生在helpedfree以前的行为。也就是说，灰鲸在被“解救”以前已经被“捕获”，而且是在“游入沿岸海域”是被“捕获”的。

8.Manyoftheshipsusedbyoceanographicinstitutionsaresmall(vessels,havingoutlivedtheiroriginalpurpose)

应该是(vesselsthathaveoutlivedtheiroriginalpurpose)这个也是通过句子意思判断吗？

【解读】

原句的分词短语havingoutlivedtheiroriginalpurpose是Manyoftheshipsaresmall的状语，即它的逻辑主语是ships，意思成了“海事部门使用的许多海船是一些小型船，它们都已经超过了原有的设计目的”。答案的that指代先行词vessels，意思是“海事部门使用的许多海船是已经超过了原有设计目的的小型船”。

原句指海事部门使用的许多海船都已经超过了原有设计目的，其中也包括大型船，而答案中的句子仅指其中的小型船已经超过了原有设计目的。

9.Thereasonthemammalisthedominantlifeforminsuchawiderangeofhabitatsis（its）abilitytomaintainasteadyinternalbodytemperatureinpracticallyanyenvironment.

答案E就是没错，为什么REASONis表语直接用一个事物而非接that+句子

【解读】

◎本句的结构如下：

主句：Thereasonis(its)abilitytomaintainasteadyinternalbodytemperatureinpracticallyanyenvironment.

同位语从句：themammalisthedominantlifeforminsuchawiderangeofhabitats（美语经常省略引导同位语从句的连接词that）

◎例句D的结构如下：

主句：Theshiftfromtraditionaltocosmeticdentistryisoccuring由传统牙科到美容牙科的改变正在出现

【主要成分】Theshiftisoccuring

【后置定语】fromtraditionaltocosmeticdentistry

原因状语从句：becauseadultsaregettingfewercavitiesandbecomingmorevain其原因是患龋齿的成人越来越少并且却变得更爱虚荣。

◎例句A的结构如下：

主句：Theshiftfromtraditionaltocosmeticdentistryis

表语从句：becauseadultsaregettingfewercavitiesandbecomingmorevain

整个意思变成“由传统牙科到美容牙科的改变是因为患龋齿的成人越来越少并且却变得更爱虚荣”

◎D指这种现象正在发生，A指这种现象已经存在。
