1.在从句中，对以下连接词和引导词要保持高度警惕：

(1)which(或代词it)绝对不可指代前面的整个句子;

(2)because不可引导名词性从句;

(3)宾语从句中引导词that一般不能省略;

(4)if绝不可以引导名词性从句，如要表示“是否”，只能用whether引导;

(5)对不作为介词宾语的事物作限定性修饰，只用that而不用which。而which 仅用于引导对介宾进行修饰的限定性从句和引导非限定性从句。

2.在require、demand等表“建议、命令”意义的词之后的that从句，要求用虚拟语气动词，即动词原形，不加should。

3.绝对不可以单独使用that指代前面的单数或不可数名词，而一般是用that of+n.结构指代或换用其他表达方式。

4.绝不可以单独使用this、these来指代前面出现的单数或复数名词，而绝对要通过换用其他人称代词，或重复前面出现的名词或者改变句子结构来避免这样非正式且模糊的指代。如sth. of this kind, like this /these等模糊表达均要用such+n.(n.即重复this、these所指代的对象)来取代，意为“这些……”。另外，在“such……that”结构中，such只修饰具体名词，而不修饰抽象名词(如rapidity、severity等)。

5.在我们通常使用的there be句型中，以下表达必错：

(1)there could be done sth.;

(2)there be sth. done;

(3)there being+名词词组

(4)there was sth.(抽象的表动作的名词)，如说there was a transmisscion 万万不可。呈般来说，there be仅用于“某处有某物”，而此物是指一具体名词，如knife，star，wolf等，而非抽象名词conversion, relation等。

6.表示某人有某种能力做某事，最佳答案的选择依据是can do>be able to do>has(hav e) ability to do>has(have) a capability of doing…在选择时，有can do就不用含be able to do的选项，依次类推。

7.当我们需要举例时，一律用such as结构，而不用like。

8.倾向于用主动语态而非被动语态，当用主动或被动语态的选项在语法和句意上都无错误时，选择用主动语态表达的选项，即“主动优先原则”。

9.关于being的以下使用必错：

(1)being+n.(2)being+adj.(3)as being+n./adj./v.ving.;

10.当我们对一动宾结构进行替代时，不用do it,一律用do so.;

11.介词短语：on account of, because of, despite(in spite of ), as a result of之后只跟简单的各词短语。若其后跟的是动名词或名词所有格+动名词短语，或名词短语之后用一复杂的现在分词来修饰时，应改为与其相同意义的连词because, although等引导的从句形式。

12.几种简单的表达方式：

(1)n. that is (are) adj.必然要换为ad.+n.的名词短语结构，如a man who is poor的选项必错，而应选含有a poor man的选项。

(2)当表示谓语部分，尤其是表示实义动词的含义时，就直接用其动词形式表示，而不要用名词形式或形容词形式，如：be a cause就一定会被cause(动词)替代;be suggestive of一定会被suggest替代。

(3)一些常见词的替换方式：not any一定会被no替代;that which一定会被what替代;hav ing been done会被done(限定词)所替代。

13.平行结构的最后一个成立之前必定有一个连词and, or, neither, nor或

as well as,否则嘴并列结构必存在问题。如：to do A. do B, do的表达就必死无疑，正确表达应该是to do A, do B, and do C或to do A, to do B, and to do C。

14.在平行结构中，对于“不是……而是”的结构，ETS更喜欢用rather than,而很少用inst ead of。实践中，若5个选项中存在这两个词的互换，直接在

含rather than的选项中找答案，除非含rather than的结构有语法或逻辑错误，才可考虑instead of。

15.若在题中的划线部分(即A选项)中发现情态动词，那么在最后的正确答案中必须有些情态动词或类似语气的词出现。实践中，此原则可转化为：不含此情态动词或类似语气词的选项均为错误选项，立即排除。

从上面的分析中我们就可以看到SAT语法考试的出题点都是非常有特点的，很多情况下都是只出现在SAT语法考试中的，所以大家在备考的时候，一定要有所准备，这样才能有更多更好的选择。

We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist(免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could not. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn

off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.

Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don't develop sleep disturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can control. Such findings reinforce psychologists' suspicions that the experience or perception of helplessness is one of the most harmful factors in depression. One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975 psychologist Robert Ader at the University of Rochester School of Medicine conditioned(使形成条件反射) mice to avoid saccharin(糖精) by simultaneously feeding them the sweetener and injecting them with a drug that while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader reexposed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlier conditioning died. He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.
