PASSAGE 33

Researchers in the field of psychology have found that one of the best ways to make an important decision, such as choosing a university to attend or a business to invest in, involves the utilization of a decision worksheet. Psychologists who study optimization compare the actual decisions made by people to theoretical ideal decisions to see how similar they are. Proponents of the worksheet procedure believe that it will yield optimal, that is, the best decisions. Although there are several variations on the exact format that worksheets can take, they are all similar in their essential aspects. Worksheets require defining the problem in a clear and concise way and then listing all possible solutions to the problem. Next, the pertinent considerations that will be affected by each decision are listed, and the relative importance of each consideration or consequence is determined. Each consideration is assigned a numerical value to reflect its relative importance. A decision is mathematically calculated by adding these values together. The alternative with the highest number of points emerges as the best decision.

Since most important problems are multifaceted, there are several alternatives to choose from, each with unique advantages and disadvantages. One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables than their minds can generally comprehend and remember. On the average, people can keep about seven ideas in their minds at once. A worksheet can be especially useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question What will I do after graduation? A graduate might seek a position that offers specialized training, pursue an advanced degree, or travel abroad for a year.

A decision-making worksheet begins with a succinct statement of the problem that will also help to narrow it. It is important to be clear about the distinction between long-range and immediate goals because long-range goals often involve a different decision than short-range ones. Focusing on long-range goals, a graduating student might revise the question above to What will I do after graduation that will lead to successful career?

1. What does the passage mainly discuss?

(A) A tool to assist in making complex decisions.

(B) A comparison of actual decisions and ideal decisions

(C) Research on how people make decisions

(D) Differences between long-range and short-range decision making

2. The word essential in line 7 is closest in meaning to

(A) introductory

(B) changeable

(C) beneficial

(D) fundamental

3. The word pertinent in line 9 is closest in meaning to

(A) relevant

(B) preceding

(C) insightful

(D) responsive

4. Of the following steps, which occurs before the others in making a decision worksheet?

(A) Listing the consequences of each solution

(B) Calculating a numerical summary of each solution

(C) Deciding which consequences are most important

(D) Writing down all possible solutions

5. According to decision-worksheet theory, an optimal decision is defined as one that

(A) has the fewest variables to consider

(B) uses the most decision worksheets

(C) has the most points assigned to it

(D) is agreed to by the greatest number of people

6. The author develops the discussion in paragraph 1 by means of

(A) describing a process

(B) classifying types of worksheets

(C) providing historical background

(D) explaining a theory

7. The author states that On the average, people can keep about seven ideas in their minds at

once (lines 17-18) to explain that

(A) most decisions involve seven steps

(B) human mental capacity has limitations

(C) some people have difficulty making minor as well as major decisions

(D) people can learn to keep more than seven ideas in their minds with practice

8. The word succinct in line 24 is closest in meaning to

(A) creative

(B) satisfactory

(C) personal

(D) concise

9. Which of the following terms is defined in the passage ?

(A) Proponents (line 5)

(B) Optimal (line 5)

(C) Variables (line 17)

(D) Long-range goals (line 25)

10. The word it in line 24 refers to

(A) worksheet

(B) problem

(C) distinction

(D) decision

11. The word revise in line 26 is closest in meaning to

托福阅读怎么抓住定位词

首先介绍一下，什么是定位词?

其实很简单，打个比方，你和朋友约好了去酒吧，朋友和你说酒吧在沈阳新东方正对面，这个酒吧你是不知道地点的，也就是你的目的地;而新东方却很熟知，那么你只需找到新东方便可以找到酒吧了。在这里新东方是已知的，就是用来定位的词汇，而酒吧则是你的目的所在，也便是你要找的答案。

定位词的称呼有很多，如关键词，主旨词，功能词，中心词等等。这些只是个名称罢了，含义都是一致的：一个可以根据题干回原文定位，并能够找到出处的词，这个题干中的词就是定位词 or key word。

定位词有什么样的特征?

定位词总体特征：不可变性和细节性

不可变性：定位词是用来定位的，所以必须找那些回原文依然不变的词汇，才有意义。通常不用动词和副词来定位。通常是名词或充当定语的形容词。

细节性：不要找大概念的词汇，更不要拿代表全文主旨的词汇来定位。换句话说不要找那些原文一大堆的词汇，无法定位。

如， 95年英国剑桥委员会British Council给出的唯一样题文章的题目是:The Spectacular Eruption of Mount St.Helens

下面有一道选择题是“ According to the text the eruption of Mount St.Helens and other volcanoes has influenced our climate by…”

拿这道题为例，如果大家把Mount St.Helens 作为关键词回原文进行定位，那你会郁闷致死，全文主要讲的就是圣海伦斯火山的喷发，原文有N多个Mount St.Helens，所以即使这个词属于大写的专有名词，但他违背了细节性，是概括性的词汇，也不能作为定位词来寻找答案。

究竟哪些词在阅读当中充当定位词?

以下是定位词的分类：

1.特殊词汇

在阅读中有一些词张的比较特殊，这种词很容易被记住，也很容易回原文定位。

好比，在大街上上看到一个人光着身子跑步-------特殊难看

一个人的个子超高，像姚明一样------特殊长

一个人身上穿着10多种颜色的衣服，而且不停的摇头-----特殊怪

特殊怪，特殊长，特殊难

这三种词就是特殊词的所有特征，在文中看到这样的词，一定要警惕。如，

Sequoia 美洲杉 ---特殊怪，很好定位，也经常作为考点。

sodium 【化学】钠---特殊难，大家只要知道是一种化学元素足矣。

Simultaneous 同时的---特殊长，这种词本身的特点决定应作为定位词。

2.数字：通常指时间，金钱和百分比。

有一个道题目是这样问的：

“What are the dates of the TWO major eruptions before 1980?”

那么像1980 3185$ 69%这些词因为长相原因，段落全是英文，突然跑出来几个数字，十分显眼，也就很好回原文找到他们。

3.专有名词：斜体字，大写人名,地名，大写的专有名词，这一点大家都很熟悉，不用多说。

4.特殊符号：

在特殊符号里或者旁边的词，最好通过符号回原文进行定位，如“paper conversation”，(three cubic miles) 这些词本身并没有什么特别，但放在符号里面，就可以根据符号回原文进行寻找。

总之，在国外考试的阅读中，无论是阅读文章，还是回答后面的10几道题目，定位词的寻找，都是一种有效的应试策略，更是学术文章的阅读的重要方法。

托福阅读不同题型的方法和技巧

一、单词题目

平时注意单词量的积累，力求达到可以随时随地记忆单词的境界。其实我们在记忆单词的时候也可以适当地使用一些策略，那就是在我们可以把自己的侧重点放在动词和形容词的记忆上。考试过后，你就会发现这个策略的事半功倍了。此外，对于自己不认识的单词，我们应该主动回原文找同义词，或找相关的提示信息。

二、找代词指代对象的题目

在考试中，它们主要会以如下两种形式出现。

(1)it、one、their、its、that类，这种题目主要是考查我们对于并列关系的掌握，这时，我们应该主动去看这个词所在的那整句话，从已知话中找到处于相同地位的词。

(2)考查由that、which涉及到的定语从句类，我们在面对这种题目时，应该有意识的在选项中找从句中谓语动词的发起者或接受者，因为只有这样才可以迈出通向胜利的第一步。

三、考查文章内容的题目

在历次的托福考试中，也存在着两大主要题型，即：文章细节考查题和文章结构考查题。

1、文章细节考查题

解答文章细节考查题，我们一般都可以回到原文中去做定位，找到相近或相似的内容，进而得出答案。

常见的定位有以下3种：

(1)题目本身给出定位。

(2)至少先可作出一个段落的定位。

(3)位置多夹于前后两题位置之间。

2、文章结构考查题

一定要注意：

(1)千万不要根据你读的信息去作推理。

(2)不要把文章从头到尾当成一个整体，尽可能各段独立。

(3)根据经验，在考试中，整篇文章的最后一句出题较多，所以应该仔细阅读这个重要的句子。

以上是针对托福考试阅读部分的常见题型做出的一些有关于考试解题方法与技巧的分项介绍。

在整个的阅读考试中，我们还应该了解到：

(1)在这个特殊的考试时间段内，我们的记忆比理解更为重要，在解题的时候一定要完全忠实于原文，切忌私自做出任何的主观臆断。

(2)在做题步骤方面，我们可以先简读原文(主要是各个段落的第一，二句话)，而后阅读题目，最后观察选项做出判断。值得我们特别注意的是，我们在做出判断的时候，切忌不要选择在选项中存在比较，而在原文中没有明确表示过的项目;切忌不要去选择那些说法过于绝对化的选项。

老托福阅读passage33试题及答案 第3篇

Potash (the old name for potassium carbonate) is one of the two alkalis (the other being soda, sodium carbonate) that were used from remote antiquity in the making of glass, and from the early Middle Ages in the making of soap: the former being the product of heating a mixture of alkali and sand, the latter a product of alkali and vegetable oil. Their importance in the communities of colonial North America need hardly be stressed.

Potash and soda are not interchangeable for all purposes, but for glass- or soap-making either would do. Soda was obtained largely from the ashes of certain Mediterranean sea plants, potash from those of inland vegetation. Hence potash was more familiar to the early European settlers of the North American continent.

The settlement at Jamestown in Virginia was in many ways a microcosm of the economy of colonial North America, and potash was one of its first concerns. It was required for the glassworks, the first factory in the British colonies, and was produced in sufficient quantity to permit the inclusion of potash in the first cargo shipped out of Jamestown. The second ship to arrive in the settlement from England included among its passengers experts in potash making.

The method of making potash was simple enough. Logs was piled up and burned in the open, and the ashes collected. The ashes were placed in a barrel with holes in the bottom, and water was poured over them. The solution draining from the barrel was boiled down in iron kettles. The resulting mass was further heated to fuse the mass into what was called potash.

In North America, potash making quickly became an adjunct to the clearing of land for agriculture, for it was estimated that as much as half the cost of clearing land could be recovered by the sale of potash. Some potash was exported from Maine and New Hampshire in the seventeenth century, but the market turned out to be mainly domestic, consisting mostly of shipments from the northern to the southern colonies. For despite the beginning of the trade at Jamestown and such encouragements as a series of acts “to encourage the making of potash,” beginning in 1707 in South Carolina, the softwoods in the South proved to be poor sources of the substance.

1. What aspect of potash does the passage mainly discuss?

(A) How it was made

(B) Its value as a product for export

(C) How it differs from other alkalis

(D) Its importance in colonial North America

2. All of the following statements are true of both potash and soda EXPECT:

(A) They are alkalis.

(B) They are made from sea plants.

(C) They are used in making soap.

(D) They are used in making glass.

3. They phrase “the latter” in line 4 refers to

(A) alkali

(B) glass

(C) sand

(D) soap

4. The word “stressed” in line 6 is closest in meaning to

(A) defined

(B) emphasized

(C) adjusted

(D) mentioned

5. The word “interchangeable” in line 7 is closest in meaning to

(A) convenient

(B) identifiable

(C) equivalent

(D) advantageous

6. It can be inferred from the passage that potash was more common than soda in colonial North America because

(A) the materials needed for making soda were not readily available

(B) making potash required less time than making soda

(C) potash was better than soda for making glass and soap

(D) the colonial glassworks found soda more difficult to use

7. According to paragraph 4, all of the following were needed for making potash EXCEPT

(A) wood

(B) fire

(C) sand

(D) water

8. The word “adjunct” in line 22 is closest in meaning to

(A) addition

(B) answer

(C) problem

(D) possibility

9. According to the passage , a major benefit of making potash was that

(A) it could be exported to Europe in exchange for other goods

(B) it helped finance the creation of farms

(C) it could be made with a variety of materials

(D) stimulated the development of new ways of glassmaking

10. According to paragraph 5, the softwoods in the South posed which of the following problems for southern settles?

(A) The softwoods were not very plentiful.

(B) The softwoods could not be used to build houses.

(C) The softwoods were not very marketable.

(D) The softwoods were not very useful for making potash.

托福阅读的满分训练方法

1.词汇

从某种意义上来讲，词汇量的大小是TOEFL阅读理解高分的基础和关键。如果词汇量没有达到基本要求(五千以上)，纵然你有“葵花宝典”在手，也只能命丧ETS的“毒招”之下。所以，以牺牲词汇量为代价的技巧练习简直是一味巨毒无比。

2.通过练习使学生养成高效的阅读方法——即所谓的阅读技巧

TOEFL的阅读量非常大，一般的中国考生根本无法把文章全部读完，所谓的“扫读法”、“跳读法”和“略读法”也只能适用于少数类型的文章，根本不能解决本质问题。那么，文章到底应该怎么读法呢?一句话，主动地阅读文章的关键部位。所谓主动是指不能象一般的阅读那样完全被动地接受信息，而应该不断的进行思考和预测;所谓关键部位，主要是每一段的开头和结尾部分。由于TOEFL的阅读理解文章全部选自于正式出版物，文章的逻辑结构非常完整和严谨，而且出现的逻辑模式也是屈指可数。经过系统的训练，考生的预测可以做到非常准确的程度。这样，通过阅读文章的几处关键部位，就能很快地把握整个文章的结构和内在的逻辑关系，也就解决了问题的70%.

3.解题训练

排除法恐怕是一直以来大多数学生在解阅读理题目时使用最多的方法。事实上，这种方法具有致命的缺点：干扰大、费时间。更有效和迅速的办法是读完题干之后，就在脑子反映出一个模糊的或者是不完整的答案，然后直接在选项中寻找接近的答案进行判断。这种能力必须在平时的训练和讲解中逐渐养成和加强，决非什么技巧之类的东西可以替代。

除了上述三方面的训练之外，如果能够对一些基本的背景知识加以补充的话，更能确保阅读理解的准确率和速度。

怎么提高阅读理解分数?

所以对于这部分考生，大家备考时就要特别注意托福阅读的题型以及主题的练习，这样才能_你的托福阅读考试总是低分的尴尬，下面小编就带大家一起来认识一下托福阅读的题型及主题，希望对大家有帮助。

1、题型——注重解题方法

托福阅读10种题型，除最后的小结题外大都属于考查文章细节的题目。根据题干中的关键词定位是至关重要的一步，然后就是理解。此时如果词汇量太小怎么办?事实上做阅读我们永远要牢记的就是找句子主干，考查的信息基本都在主干中体现了，

比如：The deer which once picturesquely dotted the meadows around the fort were gone [in 1832], hunted to extermination in order to protect the crops.

这个句子较长，其中有which引导的定语从句，还有hunted… 这个状语，而解题时我们只需要句子的主干The deer were gone。多数同学在做题时有个习惯就是看到一句话后就开始逐词阅读，甚至试图把它翻译成中文，这可谓“兵家大忌”。

遇到一句话先抓主干，遇到整段记得扫描段落有无显眼的连词，举例信号词等，浏览每段的主题句。

再说一下小结题，大多数考生的切肤之痛。一是做到最后一题时时间已所剩无几，二是最后一题是对全文的主要内容的总结，相对复杂。

在课堂中，我一再向学生强调把握全文结构及大意的重要性，而如何去把握?

一是做题之前可大概浏览文章的标题及每段首句。作为学术性的阅读文章，首句基本都是主题句。尤其是总分结构的文章，比如练习题6中的Infantile Amnesia, 虽然文章较难理解，但是文中明确提出了三种观点first，second，third… 那么此类文章小结题的选项太显而易见了。再者，文章的每段会对应出2-3道题，那么题目中对应的部分基本都是段落的核心所在。从这两点就可以很快了解文章的主要内容。所以在进行练习题练习时，做题虽不可或缺，但还要注意多加练习快速阅读文章的能力。

2、主题——增加背景知识

有部分学生反映做阅读时很难投入进去，有一点原因就是对于文章所述内容太过陌生，如果你对其略知一二，相信定会有所不同。比如练习题中有篇文章讲到化学元素周期表，对于高中生来说再熟悉不过了，阅读的时候半读半猜，估计也可以理解的八九不离十了。

若考试准备时间充足，可以多加涉猎，扩充自己的知识背景;若时间紧张，则需搞定练习题套题。根据文章记忆单词，并不是文章中出现的每一个“陌生的面孔”都要去熟悉，比如一些繁琐的专有名词跳过即可。主要记忆的当然是一些动词、名词及形容词，尤其是出现在句子主干中，与解题有关的词汇。

除了词汇，应学会分析题干及题目，比如题干中出现了effect，conclusion之类的词，其实已经界定了我们寻找的范围——段落靠后的部分，还有就是观点性和总结性的句子永远会是考察的重点所在。做题的时候学会分析原文和选项，进行对比，比如句子简化题，做一题需要看五个长句，似乎很花费时间，但并不需要每个句子都要细看，而是先明确原句的逻辑及主干，抓住选项中的关键点与原句进行比较。

例如：As a result of crustal adjustments and faulting, the Strait of Gibraltar, where the Mediterranean now connects to the Atlantic, opened, and water cascaded spectacularly back into the Mediterranean.A. The strait of Gibraltar reopened when the Mediterranean and the Atlantic became connected and the cascades of water from one sea to the other caused crustal adjustments and faulting.B. The Mediterranean was dramatically refilled by water from the Atlantic when crustal adjustments and faulting opened the Strait of Gibraltar, the place where the two seas are joined.C. The cascades of water from the Atlantic to the Mediterranean were not as spectacular as the crustal adjustments and faulting that occurred when the Strait of Gibraltar was connected to those seas.D. As a result of crustal adjustments and faultin;g and the creation of the Strait of Gibraltar, the Atlantic and Mediterranean were connected and became a single sea with spectacular cascades of water between them.

原句是因果逻辑的句子，先找出其因： crustal adjustments and faulting，果：the Strait opened, and water cascaded spectacularly back into the Mediterranean.接着来看选项：A…. caused crustal adjustments and faulting 显然是因果倒置了，毫不犹豫地灭掉;C. 因为此选项中出现比较not as spectacular as, 非常惹眼的一个核心词，而原文中是修饰动词的副词spectacularly，并未进行比较，二话不说也排除掉;D. As a result of crustal adjustments and faulting and the creation of the Strait of Gibraltar,… 这原因里怎么多出来一项啊，掳袖子撵人吧!

管中窥豹，可见一斑。由此例可见找关键，作分析可帮助我们快速并且准确的找出选项。值得注意的一点是：无论解题方法多么巧妙，离开了大量的练习就是“无本之源”。

如何备考托福阅读?

一、托福阅读答题顺序错误

顺序影响速度，进而影响考试得分。

考生在托福阅读答题时究竟是先看文章还是先读题，就跟“先有鸡还是先有蛋”的问题一样难解，若你还没有找到一个较合理的做题顺序，不妨按照下面的流程来：

先看题，再看每道题目标示出的其对应的段落，并在该段中进行考点定位，阅读，最终选出答案。这样比较容易取得托福阅读高分。

二、托福阅读答题思路错误

常听学生说“这道题做错是因为我当时想多了”。托福阅读的选项之间意思很贴近。而托福阅读基本是在考paraphrase(释义)。

那么在做题的时候一定要注意：答案都是在文中能直接找的到的，不要去做任何推断，哪怕是所谓的推断题。

三、托福阅读答题技巧运用不熟练

首先，我们做题时要时刻保持主动性。这里的主动是指在读文章的时候应主动思考并预判下文以及出题点。并且这招也是很多高分学员分享的经验。那么，“采取主动预判的做题方式，能够帮助你更快的完成题目”这就是一种做题技巧。

不过，知道了技巧和会运用可是两码事。如何熟练的运用?要做系统的训练：托福阅读的每篇文章的逻辑结构都是很严谨的，并且这种严谨的逻辑模式也是屈指可数。

四、阅读核心基本功-单词量不够

很多25/26分的学生刷了数次托福阅读依旧没有满分，分析原因发现他们有一个共性，那就是单词背的不扎实。单词不过关，很容易对题目和文章内容的理解产生偏差。因为你只有看懂了，才会明白题意，才知道如何答题。不以词汇量为基础的所有做题技巧都是不可靠的。所以还是得踏踏实实背单词!

老托福阅读passage33试题及答案 第4篇

Plants are subject to attack and infection by a remarkable variety of symbiotic species and have evolved a diverse array of mechanisms designed to frustrate the potential colonists. These can be divided into preformed or passive defense mechanisms and inducible or active systems. Passive plant defense comprises physical and chemical barriers that prevent entry of pathogens, such as bacteria, or render tissues unpalatable or toxic to the invader. The external surfaces of plants, in addition to being covered by an epidermis and a waxy cuticle, often carry spiky hairs known as trichomes, which either prevent feeding by insects or may even puncture and kill insect larvae. Other trichomes are sticky and glandular and effectively trap and immobilize insects.

If the physical barriers of the plant are breached, then preformed chemicals may inhibit or kill the intruder, and plant tissues contain a diverse array of toxic or potentially toxic substances, such as resins, tannins, glycosides, and alkaloids, many of which are highly effective deterrents to insects that feed on plants. The success of the Colorado beetle in infesting potatoes, for example, seems to be correlated with its high tolerance to alkaloids that normally repel potential pests. Other possible chemical defenses, while not directly toxic to the parasite, may inhibit some essential step in the establishment of a parasitic relationship. For example, glycoproteins in plant cell walls may inactivate enzymes that degrade cell walls. These enzymes are often produced by bacteria and fungi.

Active plant defense mechanisms are comparable to the immune system of vertebrate animals, although the cellular and molecular bases are fundamentally different. Both, however, are triggered in reaction to intrusion, implying that the host has some means of recognizing the presence of a foreign organism. The most dramatic example of an inducible plant defense reaction is the hypersensitive response. In the hypersensitive response, cells undergo rapid necrosis — that is, they become diseased and die — after being penetrated by a parasite; the parasite itself subsequently ceases to grow and is therefore restricted to one or a few cells around the entry site. Several theories have been put forward to explain the basis of hypersensitive resistance.

托福阅读技巧：词汇题应对方法

为什么很多考生会对词汇题束手无措?一方面是因为考生的词汇量达不到，OG中词汇题的解释里有一句话，there is no “list of words” that must be tested. 这句话就告诉考生死了那条心去背所谓的大纲词汇，因为没有大纲，而考试中要考查到的单词可能是来自牛津字典或朗文字典中的任何一个单词，范围大的离谱;而另一方面则是因为有的考生没有学会从上下文或者从语法结构去猜测词义。

因为OG中的解释还有一句a word might have more than one meaning, but in the reading passage, only one of those meaning is relevant. 所以很有可能考生在考试中所碰到的词汇并不是已经让人熟知的第一词义，而是要根据语境上下文推断出的第二词义甚至是第三词义，所以又对考生做题增加了难度。最可悲的是不仅文章中的单词意思不知道，连4个选项中的单词都有不认识不熟悉的，这样的结果就只能是乱猜一气，听天由命全凭运气，当然考试结果也不会好。所以在此将给考生一点准备新托福阅读考试词汇题的建议和解题方法，希望能给考生攻克词汇题给予一些帮助。

Tip: 单词记忆

单词记忆主要就是背单词。背单词是很多同学觉得非常痛苦的事情，经常会有学生来问药怎么背，背了一些又马上忘了另外一些。所以关于如何去背单词，在这里有几点建议：

1、利用零散的时间背单词。利用零散的时间背单词可以使用单词卡片。不过，为了保证效率，首先要确定哪些单词需要记忆。理论上，单词量越多越好。实际上，如果一味贪多，结果容易打疲劳战，而且效率低。所以，只记那些常考的核心词汇，而对于那些不太常用的学科名词、物质名词一般加以忽略。

2、进行高频率的重复，建议把重复的周期控制在7天以内。具体说来，就是每天背100个单词，将过一遍这些单词的时间控制在半个小时以内，每天过4遍，第二天再过一遍前一天的。如果程度不是很好的同学可以压缩到50个左右，但尽量不要低于50个。单词材料可以找一些相关的新托福阅读词汇书，或者是以往考过的词汇题内容。

把背单词和阅读相结合。广泛的阅读也是增加词汇量的一种方法，并且能够在阅读中加强对已经背过的单词的记忆。当一篇文章的生词量在5%左右的时候，这些生词的词义是可推的。所以我们在选择阅读材料的时候，应尽量将单词量控制在10%左右。单词太多，看不懂文章，太少又起不到提高的作用。相关材料可以上一些网站看，例如economist, national geographic等等。

托福技巧：巧用出题规则 实现托福阅读高分

一、列举和并列句

列举指的是： First, Second, Third,等逐条列出。并列句是指： A ， B and C ，即逐项列出。它们共同的特征是列出二点或三点以上的条目。该类型语言点常考的题型是“细节性问题”，主要有两种：

1. Which 题型

该题型只要求从并列的三顶中选一项作为答案，其它条目与题目无关。在这种情况下，往往题目的答案出自最后一个选项 。

2 . EXCEPT 题型

该题型俗称“三缺一”题型，即题目 4 个选项中有三个符合文章内容，剩下一个不符合，题目便是要求选出这个不符合文章内容的选项。例如： All of the following are mentioned as types of evidence concerning handedness EXCEPT ?

这种题型只适合于考并列、列举句，这是因为它要求其三个选项一定是文章中出现的，也就是并列或列举之处。利用这一特点.我们在读文章的时候就可多留意，如看到并列、列举句，可预想其有可能被考到;如发现题目中有“三缺一”题型，则应到并列、列举处找答案。

二、否定及转折句

否定句是指带有 NO 或 NOT ， NEVER 等否定词的句子，而转折句则指带有 HOWEVER ， BUT 或 RATHER 等关联词引导的句子，它们可以用下面的句型说明： A is not B ， as C ， but is D 。对于以上的句型常出“推断性问题”。

三、举例句

句中由 as 或 such as ， for example 等引导的短语或句子为举例句，常考“推断性问题”和“细节性问题”。上面句型中的 as C 为插入的举例句。

四、数字与年代

文中的数字、年代、日期等常常是出题者注意的考题点。

五、最高级及绝对性词汇

文章中若出现 must ， all ， only ， anyone ， always ， never 等绝对性词汇或 first ， most beautiful 等最高级词汇，往往是考题要点，一般出“细节性题目”。这是因为它们都有一个共同的特点，那就是 概念绝对 ， 答案唯一 ，无论是出题还是做题，不会产出歧义和疑问，因此很容易出题，答案绝对正确。

相反地，如果文章中出现相对性的词汇、例如 Some of the people chose red hats,some chose green hats,and others blue ones. 其中 some 为相对性词汇，如果我们出这样一道题： What color hats did some people choose? 那么就没有唯一正确的答案，因为有可能为 red,green 或 blue ，给评卷带来困难。

六、比较级及比喻

如果文中含有 more than 或 as ， like ( a fly )等句型，则为比较级或比喻句结构，往往也是考题点，一般出“推断性题目”。

七、同位语及插入语

文章中带有由 that is ， i.e. ， or 等词汇引导的名词词组，放在一个名词后面，为同位语;插入语是指副词、不定式、分词、从句等结构故在句首，句中或句尾，不做句子成分，但修饰整个句子、表达作者感情的语法结构。 这些用逗号隔开的持殊结构往往也是考查的重点，一般会出“细节性题目”。

八、因果句

句中若有如下结构或词汇的称为因果句：

(1) 因果连词： because ， since ， for ， as ， therefore ， so ， consequently 等

(2) 表示因果的动词： cause ， result in ， originate from 等;

需要注意的是一旦完成了一个部分的考试便无法返回该部分内容，即进入第二部分以后便无法返回第一部分，加试同理。所以大家在做题的时候要认真仔细。
