　　For months the press had praised thatcher's handling of the international crisis, and (A)editorial views changed quickly (B)when (C)the domestic economy worsened.(D) no error (E)

　　解析：

　　这句话的内在逻辑关系应该是转折的,前面说的是praised,后面说当经济变坏的时候就迅速改变观点,所以不能用and,表示并列,把and改成but,crisis是单数,复数是crises,撒切尔处理国际危机不可能是一个危机,肯定是各种各样的,所以改成复数.

　　(不是所有的and都考平行结构哦～～)

　　虚拟语气-考点新趋势!!!(考察概率：99%)

　　(E) There has been

　　1.表示与现在事实相反的情况：

　　从句：If 主语+过去时(Be动词用were)

　　主句：主语+should/would/could/might+do

　　2.表示与过去事实相反的情况

　　从句：If 主语+had+done

　　主句：主语+should/would/could/might+have done

　　3. 表示对将来情况的主观推测

　　主句：主语+should +do

　　从句：①if+主语+were to do

　　②if+主语+should/would/could/might+do

　　③if+主语+did(动词过去式)/were

　　IF 省略倒装

　　当虚拟条件句的谓语动词含有were ,should ,had时，if可以省略，这时条件从句要用倒装语序，即把were ,should ,had等词置于句首，这种多用于书面语。

　　eg：Should he agree to go there ,we would send him there.

　　要是他答应去的话，我们就派他去。

　　Were she here ,she would agree with us.

　　如果她在这儿的话，她会同意我们的。

　　一坚持 insist

　　二命令 order command

　　三建议 suggest advise recommend

　　独立主格结构：-新趋势(考察概率： 70%)

　　独立主格结构 由两部分组成，前一部分是名词或者代词，后一部分是非谓语动词(不定式、现在分词、过去分词)或形容词、副词、名词或介词短语。前后两部分具有逻辑主谓关系。独立主格结构在句中做状语，多用于书面语。 独立主格结构本身不是句子，在句子中作状语，表时间、原因、条件、伴随、目的等。

　　A great gray owl flying low (A) across a forest clearing, its wings beating (B)quietly and its ultrasensitive ears tuned to the faint sounds (C) made by small creatures concealed (D) under leaves. No error (E)

　　解析：

　　本题其实就是一道典型的独立主格结构题;这句话的意思是：“一只巨大的灰色的猫头鹰低空飞过一片森林的空地，它的翅膀拍打得很安静，它的耳朵调向一些小生物的微弱的声音。这些小生物躲在树叶底下;”猫头鹰fly 和(wings beating and ears tuned)属于整体和部分关系，要把整体当成主句;那么就应该把flying改成flies;

　　A thick growth of sunflowers standing ten feet tall, their brown heads drooped over the fence with the weight of their seeds.

　　A. standing ten feet tall, their brown heads drooped

　　B. standing ten feet tall, their brown heads drooping

　　C. standing ten feet tall, and their brown D. heads droop

　　D. stood ten feet tall, their brown heads drooping

　　E. stood ten feet tall, and their brown heads drooping

　　解析：

　　想必大家都被这道题坑过吧～尤其是在A和D两个选项之中;还是整体和部分的关系，我们应该把stood作为这个句子的重心，sunflowers的头部只是附属一部分;答案选D;

　　IP题解题攻略：

　　一、修改句子题

　　第1步：分析句子成分和结构：

　　句子成分：观察句子中是否存在主语和谓语，或者多主语或谓语;

　　句子结构：观察句子中有没有“平行结构”有没有“悬挂结构”，然后再“对症下药”;

　　第2步：动词时态和主谓一致问题;

　　第3步：代词;

　　人称代词穿越;

　　代词单复数互相指代;

　　第4步：逻辑语义：

　　判断该句和上一句的逻辑关系：转折(however);让步(although);并列(and);递进(furthermore);举例子(for example);

　　二、合并句子题

　　题目要求把两个句子合并为一个句子，做题时注意两句话之间的逻辑关系。而有些题仅通过语法(时态、人称保持一致)就可以得出正确选项，这里不赘述。下面介绍的是一种常考的“顶针句”。

　　(11)Countries may select their campers but cannot pay for the camp. (12) The camp remains unaffiliated with any nation, organization, or peace group.

　　33.In context, which version of sentences 11 and 12 best combines them into a single sentence?

　　A. Countries may select their campers but cannot pay for the camp, which remains unaffiliated with any nation, organization, or peace group.

　　B. Unaffiliated with any nation, organization ,or peace group, countries may select their campers but cannot pay for the camp.

　　C. Countries may select their campers, in addition, they cannot pay for the camp, which remains unaffiliated with any nation, organization, or peace group.

　　D. Countries cannot pay for the camp although they may select their campers, the camp remains unaffiliated with any nation, organization, or peace group.

　　E. It remains unaffiliated with any nation, organization, or peace group, and although countries may select their campers, they cannot pay for the camp.

　　解析：仔细观察句子，我们发现前一句的最后一个词和后一句的第一个词一致，直接把后一句改为定语从句最简单，句子衔接也非常自然。B Unaffiliated 的逻辑主语应该是camp而非 countries ，CD为 run—on句型，缺少连词，E it在本句中无指代，往前一句找也是无指代。

　　30.Which of the following is the best version of the under lined portion of sentence 2 (reproduced below)?

　　A recent version of Shakespeare's Romeo and Juliet drew harsh reviews from purists, they are people who expect filmmakers to follow the original text exactly.

　　A. (as it is now)

　　B. purists; they were people who expected

　　C. purists in expecting

　　D. purists. These expected

　　E. purists, those who expect

　　答案：E

　　31. Which of the following is the most effective way to combine sentences 5 and 6 (reproduced below) at the underlined part?

　　The wide availability of a relatively inexpensive mode of transportation had a particularly dramatic impact on the lives of women. Women had traditionally been much less mobile than men.

　　A. women's lives that

　　B. women's lives because they

　　C. women, their lives

　　D. the lives of women, who

　　E. the lives of women, although they

　　答案：D

　　如果大家能把这些考点都看明白，理解并记在心里的话，差不多就已经有700分了，剩下就是靠考技和赌人品的时候了～～

　　保持一个平常心，相信付出就会有回报!最后，祝广大sat考生们5月旗开得胜，取得一个圆满的分数!
