Directions: There are five reading passages in this part. Each passage is followed by five
questions. For each question there are four suggested answers marked A, B, C and D. Choose the best answer and blackening the corresponding letter on the answer sheet.

Passage One

Artificial flowers are used for scientific as well as for decorative purposes. They are made from a variety of materials, such as wax and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking skill and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artists-naturalists, Leopold Blaschka and his son Rudolph.

The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed, it contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models ate kept in locked cases, as they are too valuable and fragile for classroom use.

31. Which of the following is the best title for the passage?

A. An Extensive Collection of Glass Flowers.

B. The Live Leopold and Rudolph Blaschka.

C. Flowers Native to the United States.

D. Materials Used for Artificial Flowers.

第3题
Science is an enterprise concerned with gaining information about causality, or the relati
onship between cause and effect. A simple example of a cause is the movement of a paddle as it strikes a ping-pong ball; the effect is the movement of the ball through the air. In psychology and other sciences, the word "cause" is often replaced by the term "independent variable". This term implies that the experimenter is often "free" to vary the independent variable as he or she desires (for example, the experimenter can control the speed of the paddle as it strikes the ball). The term "dependent variable" replaces the word "effect", and this term is used because the effect depends on some characteristic of the independent variable (the flight of the ball depends on the speed of the paddle). The conventions of science demand that both the independent and dependent variables be observable events, as is the case in the ping-pong example. In the case of biorhythm theory, the independent variable is the number of days that have elapsed between a person's date of birth and some test day. The dependent variable is the person's level of performance on some specified task on the test day. Notice that although the experimenter is not free to choose a birthday for a given individual, persons with different dates of birth can be tested on the same day, or a single subject can be tested on several different days.

In order to predict the relationship between independent and dependent variables, many scientific theories make use of what are called intervening variables. Intervening variables are purely theoretical concepts that cannot be observed directly. To predict the flight of a ping-pong ball, Newtonian physics relies on a number of intervening variables, including force, mass, air resistance, and gravity. You can probably anticipate that the intervening variables of biorhythm theory are the three bodily cycles with their specified time periods. It should be emphasized that not all psychological theories include intervening variables, and some psychologists object to their use precisely because they are not directly observable.

The final major component of a scientific theory is its syntax, or the rules and definitions that state how the independent and dependent variables are to be measured, and that specify the relationships among independent variables, intervening variables, and dependent variables. It is the syntax of biorhythm theory that describes how to use a person's birthday to calculate the current status of the three cycles. The syntax also relates the cycles to the dependent variable, performance, by stating that positive cycles should cause high levels of performance whereas low or critical cycles should cause low performance levels. To summarize, the components of a scientific theory can be divided into four major categories: independent variables, dependent variables, intervening variables, and syntax.

Based on the passage, causality may have the meaning that ______.

A.cause and effect can be independent of each other

B.there is hardly anything that happens without a cause

C.dependent and independent variables affect each other

D.cause and effect may vary respectively in most events

根据下列材料,请回答 31~35 题:

In the idealized version of how science is done, facts about the world are waiting to be observed and collected by objective researchers who use the scientific method to carry out their work. But in the everyday practice of science, discovery frequently follows an ambiguous and complicated route. We aim to be objective, but we cannot escape the context of our unique life experience. Prior knowledge and interest influence what we experience, what we think our experiences mean, and the subsequent actions we take. Opportunities for misinterpretation, error, and self-deception abound.

Consequently, discovery claims should be thought of as protoscience. Similar to newly staked mining claims, they are full of potential. But it takes collective scrutiny and acceptance to transform. a discovery claim into a mature discovery. This is the credibility process, through which the individual researcher’s me, here, now becomes the community’s anyone, anywhere, anytime. Objective knowledge is the goal, not the starting point.

Once a discovery claim becomes public, the discoverer receives intellectual credit. But, unlike with mining claims, the community takes control of what happens next. Within the complex social structure of the scientific community, researchers make discoveries; editors and reviewers act as gatekeepers by controlling the publication process; other scientists use the new finding to suit their own purposes; and finally, the public (including other scientists) receives the new discovery and possibly accompanying technology. As a discovery claim works it through the community, the interaction and confrontation between shared and competing beliefs about the science and the technology involved transforms an individual’s discovery claim into the community’s credible discovery.

Two paradoxes exist throughout this credibility process. First, scientific work tends to focus on some aspect of prevailing Knowledge that is viewed as incomplete or incorrect. Little reward accompanies duplication and confirmation of what is already known and believed. The goal is new-search, not re-search. Not surprisingly, newly published discovery claims and credible discoveries that appear to be important and convincing will always be open to challenge and potential modification or refutation by future researchers. Second, novelty itself frequently provokes disbelief. Nobel Laureate and physiologist Albert Azent-Gyorgyi once described discovery as “seeing what everybody has seen and thinking what nobody has thought.” But thinking what nobody else has thought and telling others what they have missed may not change their views. Sometimes years are required for truly novel discovery claims to be accepted and appreciated.

In the end, credibility “happens” to a discovery claim – a process that corresponds to what philosopher Annette Baier has described as the commons of the mind. “We reason together, challenge, revise, and complete each other’s reasoning and each other’s conceptions of reason.”

第 31 题 According to the first paragraph, the process of discovery is characterized by its

[A] uncertainty and complexity.

[B] misconception and deceptiveness.

[C] logicality and objectivity.

[D] systematicness and regularity.

根据下列文章,回答26~30题。It used to be so straightforward. A team of researchers working t
ogether in the laboratory would submit the results of their research to a journal. A journal editor would then remove the authors names and affiliations from the paper and send it to their peers for review. Depending on the comments received, the editor would accept the paper for publication or decline it. Copyright rested with the journal publisher, and researchers seeking knowledge of the results would have to subscribe to the journal.

No longer. The Internet and pressure from funding agencies, who are questioning why commercial publishers are making money from government-funded research by restricting access to it- is making access to scientific results a reality. The Organization for Economic Co-operation and Development (OECD) has just issued a report describing the far-reaching consequences of this. The report, by John Houghton of Victoria University in Australia and Graham Vickery of the OECD, makes heavy reading for publishers who have, so far, made handsome profits. But it goes further than that. It signals a change in what has, until now, been a key element of scientific endeavor.

The value of knowledge and the return on the public investment in research depends, in part, upon wide distribution and ready access. It is big business. In America, the core scientific publishing market is estimated at between $7 billion and $11 billion. The International Association of Scientific, Technical and Medical Publishers says that there are more than 2,000 publishers worldwide specializing in these subjects. They publish more than 1.2 million articles each year in some 16,000 journals.

This is now changing. According to the OECD report, some 75% of scholarly journals are now online. Entirely new business models are emerging; three main institutional subscribers pay for access to a collection of online journal titles through site-licensing agreements. There is open-access publishing, typically supported by asking the author (or his employer) to pay for the paper to be published. Finally, there are open-access archives, where organizations such as universities or international laboratories support institutional repositories. Other models exist that are hybrids of these three, such as delayed open-access, where journals allow only subscribers to read a paper for the first six months, before making it freely available to everyone who wishes to see it. All this could change the traditional form. of the peer-review process, at least for the publication of papers.

A.the background information of journal editing.

B.the publication routine of laboratory reports.

C.the relations of authors with journal publishers.

Part A

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)

Fortunately there are still a few tasty things for us gourmands to enjoy in relative security. Their numbers, however, are depleted almost daily. It seems, by ruthless proclamations from the ever-vigilant Food and Drug Administration and its allies, our doctors. The latest felon to face prosecution is the salt of life, sodium chloride.

Ostensibly, overuse of salt muses high blood pressure and hypertension, the cause of half the deaths in the United States every year. A few years ago the anti-salt campaigners raised such a rumpus that salt was banned from baby food. Currently pressure is being applied to food manufacturers to oblige them to label their products to show sodium content. Bemuse doing so would cost mercenary manufacturers money, they argue that they have no idea how much salt remains on such things as potato chips and how much sticks to the bag. Furthermore, salt isn't the only harmful ingredient in food. If the manufacturer has to provide sodium content, why not require him to list every ingredient and specify which are detrimental to our health? Cigarettes have a warning printed on them. Shouldn't the same type of warning appear on canned foods that are notoriously over-salted?

There are endless ifs and buts in the controversy, but the most telling of these is the questionable proof of salt's diabolic effect upon blood pressure. True, people who cut their salt intake lowered their blood pressure, but where is the scientific proof that something other than salt didn't do the trick? The most common means of providing dubious proof that salt causes hyper tension is to compare societies that use little salt with those that use mountains of salt in their daily diets. Which group has the higher rate of hypertension? Whose blood pressure is lower? What happens when salt is introduced into a group where salt is a novelty? Does the blood pressure rise significantly? Studies of the Japanese indicate that as the world's greatest salters, they suffer the most from hypertension. On the other hand, the simple, salt-free cuisine of several tribes in the Solomon Islands has kept older tribesmen and women from developing hypertension and high blood pressure, ailments traditionally killing their peers in America. No account is taken of the effects of inflation, recession, pollution, crime, and sundry other ills to which Americans unlike people on primitive islands, are exposed.

To salt or not to salt? That is the question. Now that the question has arisen, it must not be treated with levity but, rather, with searching scientific investigation so that those of us who are preoccupied with both savory food and longevity may decide which of the two is worth its salt.

What is the attitude of the author of this passage toward the salt controversy?

A.We must stop eating salt immediately.

B.She is not convinced that salt is harmful.

C.The Food and Drug Administration works well with doctors.

D.Soon there won't be anything tasty left to eat.

Ask three people to look out the same window at a busy street corner and tell you what
they see.Chances are you will receive three different answers.Each person sees the same scene, but each perceives(感觉、察觉) something different about it.

Perceiving goes on in our minds.Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket.Another may say that he sees a rush-hour traffic jam at the crossing.The third may tell you that he sees a woman trying to cross the street with four children.For perception is the mind's explanation of what the senses - in this case our eyes - tell us.

Many psychologists today are working to try to decide just how a person experiences or perceives the world around him.Using a scientific method, these psychologists set up experiments in which they can control all of the factors.By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.

31.Seeing and perceiving are().

A.the same action

B.two separate actions

C.two actions carried on entirely by the eyes

D.several actions that take place at different time

32.Perceiving is an action that takes place().

A.in our eycs

B.only when we think very hard about something

C.only under the direction of a psychologist

D.in every person's mind

33.People perceive different things about the same scene because().

A.they come from different countries

B.they can't agree about things

C.some have better eyesight

D.not clearly mentioned in the passage

34.Psychologists study perception by().

A.setting up many experiments

B.asking each other what they see

C.looking out of the window themselves

D.studying the differences in people's eyes

35.The best title for this passage is().

A.How We See

B.Learning About Our Minds Through Science

C.What Psychologists Perceive

D.How to Become an Experimental Psychologist
