A close analogy to a study design is the rough sketch made by an artist before he commits
his vision to canvas(画布). The broad outlines are drawn, the proper perspective achieved, and the total impact of the picture-to-be can be partially appreciated in advance. So it is with the design of research: it specifies in advance the kinds of statements that can be made on the basis of its findings and fixes the perspectives against which these findings are to be evaluated.

One major purpose of this study was to demonstrate whether or not the newer social research techniques could help in broadening and deepening knowledge concerning juvenile delinquency(少年犯罪). Construction of the design was guided by this goal of exploring new methods in the analysis of juvenile delinquency. However, research technique developed in one content area can not be mechanically transferred to another. A new application of them requires substantial changes and it is these innovative modifications which this study offers as its contribution.

Juvenile delinquency has been the subject of many previous studies using a variety of research techniques. This study makes an additional contribution by using a design specially planned to permit a comparison of several approaches.

The drawing up of the study design profited greatly from an extensive survey of previous re searches on crime, undertaken during the earliest stage of the project. It was found that most studies could be classified as belonging to one or more of three broadly conceived types: social background study, family background study and personal motivation study.

Each type has its characteristic design and mode of interpretation and each has produced information of considerable importance. Yet not attempt was made in any of the studies to integrate one or more of these three design types. It became apparent that one of the major contributions a pilot study could make to both method and substantive findings would be to bring all three study types together in one design for the purpose of correlating(使相互关联) their findings and evaluating their relative importance in producing data of use to the practitioner.

In the first paragraph, the author draws an analogy between ______.

A.doing research and drawing a picture

B.research finding and pictures perspective

C.designing a research and making a quick drawing

D.a researcher and a painter

Nowadays, a standard for measuring power has changed. These changes foretell a new standar
d for measuring power. No longer will a nation's political influence be based solely on the strength of its military forces. Of course, military effectiveness will remain a primary measure of power. But political influence is also closely tied to industrial competitiveness. It's often said that without its military the Soviet Union would really be a third-world nation. The new standard of power and influence that is evolving now places more emphasis on the ability of a country to compete effectively in the economic markets of the world.

America must recognize this new course of events. Our success in shaping world events over the past 40 years has been the direct result of our ability to adapt technology and to take advantage of the capabilities of our people for the purpose of maintaining peace. Our industrial prowess(威力)over most of this period was unchallenged. It is ironic(有讽刺性的) that it is just this prowess that has enabled other countries to prosper and in turn to threaten our industrial leadership.

The competitiveness of America's industrial base is an issue bigger than the department of defense and is going to require the efforts of the major institutional forces in our society, government, industry, and education. That is not to say that the defense department will not be a strong force in the process. But we simply cannot be, nor should we be, looked upon by others as the savior(救星) of American industry.

Now a nation's political influence depends on______.

A.the strength of its military forces

B.its ability to compete in industry

C.economic markets

D.both A and B

Landfills

You have just finished your meal at a fast food restaurant and you throw your uneaten food, food wrappers, drink cups, utensils and napkins into the trash can. You don't think about that waste again. On trash pickup day in your neighborhood, you push your can out to the curb, and workers dump the contents into a big truck and haul it away. You don't have to think about that waste again, either. But maybe you have wondered, as you watch the trash truck pull away, just where that garbage ends up.

Americans generate trash at an astonishing rate of four pounds per day per person; which translates to 600,000 tons per day or 210 million tons per year! This is almost twice as much trash per person as most other major countries. What happens to this trash? Some gets recycled (回收利用) or recovered and some is burned, but the majority is buried in landfills.

How Much Trash Is Generated?

Of the 210 million tons of trash, or solid waste, generated in the United States annually, about 56 million tons, or 27 percent, is either recycled (glass, paper products, plastic, metals) or composted (做成堆肥) (yard waste). The remaining trash, which is mostly unredeemable, is discarded.

How Is Trash Disposed Of?

The trash production in the United States has almost tripled since 1960. This trash is handled in various ways. About 27 percent of the trash is recycled or composted, 16 percent is burned and 57 percent is buried in landfills. The amount of trash buried in landfills has doubled since 1960. The United States ranks somewhere in the middle of the major countries (United Kingdom, Canada, Germany, France and Japan) in landfill disposal. The United Kingdom ranks highest, burying about 90 percent of its solid waste in landfills.

There Are Two Ways to Bury Trash:

Dump-an open hole in the ground where trash is buried and that is full of various animals (rats, mice, birds). (This is most people's idea of a landfill!)

Landfill-carefully designed structure built into or on top of the ground in which trash is isolated from the surrounding environment (groundwater, air, rain). This isolation is accomplished with a bottom liner and daily covering of soil.

Sanitary landfill-landfill that uses a clay liner to isolate the trash from the environment.

Municipal solid waste (MSW) landfill-landfill that uses a synthetic (plastic) liner to isolate the trash from the environment.

The purpose of a landfill is to bury the trash in such a way that it will be isolated from groundwater, will be kept dry and will not be in contact with air. Under these conditions, trash will not decompose(腐烂)much. A landfill is not like a compost pile, where the purpose is to bury trash in such a way that it will decompose quickly. Proposing the Landfill

For a landfill to be built, the operators have to make sure that they follow certain steps. In most parts of the world, there are regulations that govern where a landfill can be placed and how it can operate. The whole process begins with someone proposing the landfill.

In the United States, taking care of trash and building landfills are local governments' responsibilities. Before a city or other authority can build a landfill, an environmental impact study, must be done on the proposed site to determine:

the area of land necessary for the landfill

the composition of the underlying soil and bedrock

the flow of surface water over the site

the impact of the proposed landfill on the local environment and wildlife

the historical value of the proposed site

Building the Landfill

Once the environmental impact study is complete, the permits are granted and the funds have been raised, then construction begins. First, access roa

第5题
The mental health movement in the United States began with a period of considerable enligh
tenment. Dorothea Dix was shocked to find the mentally ill in jails and almshouses and crusaded for the establishment of asylums in which people could receive humane care in hospital-like environments and treatment which might help restore them to sanity. By the mid. 1800s, 20 states had established asylums, but during the late 1800s and early 1900s, in the face of economic depression, legislatures were unable to appropriate sufficient funds for decent care. Asylums became overcrowded and prison-like. Additionally, patients were more resistant to treatment than the pioneers in the mental health field had anticipated, and security and restraint were needed to protect patients and others. Mental institutions became frightening and depressing places in which the rights of patients were all but forgotten.

These conditions continued until after World War Ⅱ. At that time, new treatments were discovered for some major mental illnesses considered untreatable (penicillin for syphilis of the brain and insuered for some major mental illnesses considered untreatable (penicillin for syphilis of the brain and insulin treatment for schizophrenia and depressions)), and a succession of books, motion pictures, and newspaper exposes called attention to the plight of the mentally ill. Improvements were made, and Dr. David Vail's Humane Practices Program is a beacon for today. But changes were slow in coming until the early 1960s. At that time, the Civil Rights Movement led lawyers to investigate America's prisons, which were disproportionately populated by blacks, and they in turn followed prisoners into the only institutions that were worse than the prisons—the hospitals for the criminally insane. The prisons were filled with angry young men who, encouraged by legal support, were quick to demand their right. The hospitals for the criminally insane, by contrast, were populated with people who were considered "crazy" and who were often kept obediently in their place through the use of severe bodily restraints and large doses of major tranquilizers. The young cadre of public interest lawyers liked their role in the mental hospitals. The lawyers found a population that was both passive and easy to champion. These were, after all, people who unlike criminals, had done nothing wrong. And in many states, they were being kept in horrendous institutions, and injustice, which once exposed, was bound to shock the public and, particularly, the judicial conscience.

Judicial interventions have had some definite positive effects, but there is growing awareness that courts cannot provide the standards and the review mechanisms that assure good patient care. The details of providing day-to-day care simply cannot be mandated by a court, so it is time to take from the courts the responsibility for delievery of mental health care and assurance of patient rights and return it to the state mental health administrators to whom the mandate was originally given. Though it is a difficult task, administrators must undertake to write rules and standards and to provide the training and patient rights are respected.

The main purpose of the passage is to ______.

A.discuss the influence of Dorothea Dix on the mental health movement

B.provide an historical perspective on problems of mental health care

C.increase public awareness of the plight of the mentally iii

D.shock the reader with vivid descriptions of asylums

There were two widely divergent influences on the early development of statistical methods
. Statistics had a mother who was dedicated to keeping orderly records of governmental units (state and statistics come from the same Latin root, status) and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, ordering, and the taking of censuses—all of which led to modem descriptive statistics. From the influence of the father came modem inferentical statistics, which is based squarely on theories of probability.

Descriptive statistics involves tabulating, depicting, and describing collections of data. These data may be either quantitative, such as measures of height, intelligence, or grade level—variables that are characterized by an underlying continuum or the data may represent qualitative variable, such as sex, college major, or personality type.

Large masses of data must generally undergo a process of summarization or reduction before they are comprehensible. Descriptive statistics is tool for describing or summarizing or reducing to comprehensible form. the properties of an otherwise unwieldy mass of data.

Inferential statistics is a formalized body of methods for solving another class of problems that present great difficulties for the unaided human mind. This general class of problems characteristically involves attempts to make predictions using a sample of observations. For example, a school superintendent wishes to determine the proportion of children in a large school system who come to school without breakfast, have been vaccinated for flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child; the proportion for the entire district could be estimated fairly accurately from a sample of as few as 100 children. Thus, the purpose of inferential statistics is to predict or estimate characteristics of a population from knowledge of the characteristics of only a sample of the population.

Which of the following are counting and describing associated with?

A.Descriptive statistics

B.Unknown variables

C.Qualitative changes

D.Inferential statistics

Learning a foreign language is not a matter of reading some grammar rules and learning
some vocabulary words — although those are important activities not to be ignored.Acquiring (学到) a language is learning a skill, not a body of information.It’s as much like learning to swim or ride a bike as it is like learning about the Second World War.That is, you must not only understand the ideas and have information at hand, but also make your body accustomed to using that information in physical activity: In this case, the physical activity is speaking, listening, writing and reading.

You need, then, not only to learn and understand, but also to practice!

Here are a few suggestions on effective practice/study techniques.

1.Make your mouth or hand do what your mind is learning.Study out loud.Do go to the lab and work on the tapes.Study with a friend, and, thus, participate in speaking and listening.Try to write sentences or a short paragraph using the skills you have practiced with your own lips.

2.Study day-by-day.You cannot get by in a foreign language course by cramming (临时抱佛脚) at the last minute.You may be able to “learn” vocabulary items that way, but you cannot teach your mouth to use them in sentences.

3.Sometimes go back and review “old”topics and vocabulary.Language learning is cumulative (累积的).You learn new skills on the basis of old ones.The more you “recycle”familiar information and skills, the better you will be able to take in new ones.

4.Don’t be afraid to make mistakes.Self-consciousness (害羞) can be a strong barrier to learning a language.Perhaps part of the reason small children readily learn languages is that they are not afraid of making mistakes.

41.The first paragraph of the passage has been written to lay stress on the fact that______.

A.memorizing vocabulary words is necessary in language learning

B.learning to swim is quite similar to learning about the Second World War

C.understanding the ideas is more important than anything else

D.language learning is a process of acquiring different language skills

42.One of the major benefits of studying with a friend is that ________ .

A.it makes one talk in a particular language

B.it builds the friendship between two friends

C.friends can share tapes or other learning materials

D.one studies better in with a friend

43.Cramming is no good while learning a language because _________.

A.it is of little use to study without a clear purpose

B.nothing can be learned through cramming

C.anything learned that way can hardly be put into use

D.one may not find enough time to use at the last minute

44.The purpose of reviewing old topics is __________.

A.to build up a good basis for new skills

B.to enjoy the good ideas contained in them

C.to throw away the old, useless information

D.to avoid making mistakes in the future

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

A.Why Children Are Able to Learn a Language Better than Grown-ups

B.A Few Suggestions on Studying a Foreign Language

C.Why Learning a Foreign Language Is More Difficult than Anything Else

D.An Introduction to Language Teaching and Learning

When you go to university to study for a degree, you have decided to study professionally, rather than as an amateur; so being a student is now your profession for at least the next four years.

This involves a change of attitude in many ways. Although the process has been going on since you went to middle school, the biggest change is going to take place. Now, instead of taking several subjects, you have chosen one major subject because you find it interesting and worth exploring further. The choice was yours. You also have the goal of getting a degree . The degree and the stages you have to pass through to achieve it give you motivation, even though it may become weak from time to time, and not all parts of the course will be exciting; a sure way to lose interest is to do too little work. It is a law of diminishing returns - the less work you do, the less interest you will have and the more bored you will become. So, regular work is needed to keep up your interest as well as to keep pace with new work.

Another change is in the relationship with teachers. This may well have changed during middle school and high school, but now the whole context is different. You are no longer forced to slay in school all day, and apart from your class time, you organize your own time and place for studying. You are there to study (an active process) rather than to be taught (passive). Your teachers may or may not urge you, but they do want you to share their interest in the subject and they want you to succeed.

Some activities, like discussing and reading, are basic to studying. Make sure that you are doing these efficiently.

Group discussions give you a chance to train yourself to speak and discuss more effectively.

Theywill fail in their purpose if you keep silentand if you start off this way, the harder it will become to get out of the situation of being the non-speaking member of the group. In the future you are almost certainly going to have to be good at speaking, so get into the way of talking about your subject now. This is actually more fun than sitting being silently miserable because you are not saving anything. Nobody will think what you say is foolish. Everyone will be thankful not to face awkward silence.

55. When does a person start to study professionally?

AThe time when he starts a profession.

BThe time when he goes to university.

CThe time when he knows how to study.

DThe time when he goes to high school.

56. Which of the following is not unique to university?

AStudents have to choose one major subject.

BThe goal of study is to get a degree.

CStudents need to work hard.

DStudents organize their own time for studying.

57. University teachers().

Adont care about studentsperformance

Bhope students can share their interest in

Cforce students to stay in school all day

Dknow nothing about their students

Amtrak(美国铁路客运公司) was experiencing a downswing in ridership(客运量) along the lines

Amtrak(美国铁路客运公司) was experiencing a downswing in ridership(客运量) along the lines comprising its rail system. Of major concern to Amtrak and its advertising agency DDB Needham, were the long-distance western routes where ridership had been declining significantly.

At one time, trains were the only practical way to cross the vast areas of the west. Trains were fast, very luxurious, and quite convenient compared to other forms of transportation existing at the time. However, times change and the automobile became America's standard of convenience. Also, air travel had easily established itself as the fastest method of traveling great distances. Therefore, the task for DDB Needham was to encourage consumers to consider other aspects of train travel in order to change their attitudes and increase the likelihood that trains would be considered for travel in the west.

Two portions of the total market were targeted: 1) anxious fliers—those concerned with safety, relaxation, and cleanliness; 2) travel-lovers—those viewing themselves as relaxed, casual, and interested in the travel experience as part of their vacation. The agency then developed a campaign that focused on travel experiences such as freedom, escape, relaxation, and enjoyment of the great western outdoors. It stressed experiences gained by using the trains and portrayed western train trips as wonderful adventures.

Advertisements showed pictures of the beautiful scenery that could be enjoyed along some of the more famous western routes and emphasized the romantic names of some of these trains (Empire Builder, etc.).These ads were strategically placed among family-oriented TV shows and programs involving nature and America in order to most effectively reach target audiences. Results were impressive. The Empire Builder, which was focused on in one ad, enjoyed a 15 percent increase in profits on its Chicago to Seattle route.

What's the author's purpose in writing this passage?

A.To show the inability of trains to compete with planes with respect to speed and convenience.

B.To stress the influence of the automobile on America's standard of convenience.

C.To emphasize the function of travel agencies in market promotion.

D.To illustrate the important role of persuasive communication in changing consumer attitudes.
