Bramley College now has full electronic information resources in the College Library to help you in your studies. On CD-ROM in the library we have about fifty databases, including many statistical sources. Want to know the average rainfall in Tokyo or the biggest export earner of Vanuatu? It's easy to find out. Whether you are in the School of Business or the School of Art Design, it's all here for you.
You can conduct your own CD-ROM search for no charge, and you can print out your results on the library printers using your library photocopying card. Alternatively, you can download your results to disk, again for no charge, but bring your own formatted floppy disk or CD-ROM. If you are not sure how to conduct a search for yourself, library staff can do it for you, but we charge $20 for this service, no matter how long or how short a time it takes.
All library workstations have broadband access to the Internet, so you can find the web-based information you need quickly and easily. If you are unfamiliar with using the Internet, help is available in several ways. You can start with the online tutorial Netstart; just click on the Netstart icon the Main Menu. The tutorial will take you through the basic steps to using the Internet, any time convenient to you. If you prefer, ask one of the librarians for internet advice (best at quiet times between 9.00am and 11.30 am weekdays) or attend one of the introductory group sessions that are held in the first two weeks of each term. Sign your name on the list on the library Bulletin Board to guarantee a place, as they are very popular.
A word of warning: demand for access to library workstations is very high, so you are strongly advised to book a workstation, and we have to limit your use to a maximum of one hour at any one time. Make your booking (for which you will receive a receipt) at the Information Desk at the enquiry desks in the Media Services Area (Level 1). Also, use of the computers is limited to Bramley students only, so you may be asked to produce your Student Identification Card to make a booking, or while using the workstations.
To ensure efficient access to the library workstations, students should…
A. conduct as many searches as possible at one time.
B. reserve a time to use a workstation.
C. queue to use a workstation in the Media Services Area.
D. work in groups on one workstation.

Almost everyone with or without a computer is aware of the latest technological revolution destined to change forever the way in which humans communicate, namely, the Information Superhighway, best exemplified by the ubiquitous Internet. Already, millions of people around the world are linked by computer simply by having a modem and an address on the 'Net', in much the same way that owning a telephone links us to almost anyone who pays a phone bill. In fact, since the computer connections are made via the phone line, the Internet can be envisaged as a network of visual telephone links. It remains to be seen in which direction the Information Superhighway is headed, but many believe it is the educational hope of the future.
What is the main point of the paragraph?
A. No-one knows where the Information Superhighway is headed.
B. You need a modem and an address to use the Internet.
C. Almost everyone has heard of the Information Superhighway.
D. The Internet will revolutionise the way people communicate.

A monarchy is a form of government where a single ruler is the head of state. It is one of the oldest forms of government in the world. Monarchs are usually kings or queens. But they can also be a chief, an emperor, or called by another name. In some countries, such as , the monarch is merely symbolic. They are figureheads with no real power. In other countries, the monarch wields considerable power. There are currently 29 sovereign monarchies around the world.
Hereditary monarchy is the most common style of succession. This form is used by most of the world's monarchies. In this case, all of the kings and queens come from the same family. A family that rules for a span of time is called a dynasty. The crown is passed down from one member to another member of the family. The hereditary system has the advantages of stability, continuity, and predictability. Family affection and loyalty are also stabilizing factors.
According to the passage, hereditary monarchy is
A. a form of absolute monarchy
B. a figurehead position
C. the most common style of succession
D. also called a tsar

The first two decades of this century were dominated by the microbe hunters. These hunters had tracked down one after another of the microbes responsible for the most dreaded scourges of many centuries: tuberculosis, cholera, diphtheria. But there remained some terrible diseases for which no microbe could be incriminated: scurvy, pellagra, rickets, beriberi. Then it was discovered that these diseases were caused by the lack of vitamins, a trace substance in the diet. The diseases could be prevented or cured by consuming foods that contained the vitamins. And so in the decades of the 1920's and 1930's, nutrition became a science and the vitamin hunters replaced the microbe hunters.
In the 1940's and 1950's, biochemists strived to learn why each of the vitamins was essential for health. They discovered that key enzymes in metabolism depend on one or another of the vitamins as coenzymes to perform the chemistry that provides cells with energy for growth and function. Now, these enzyme hunters occupied center stage.
You are aware that the enzyme hunters have been replaced by a new breed of hunters who are tracking genes-the blueprints for each of the enzymes-and are discovering the defective genes that cause inherited diseases-diabetes, cystic fibrosis. These gene hunters, or genetic engineers, use recombinant DNA technology to identify and clone genes and introduce them into bacterial cells and plants to create factories for the massive production of hormones and vaccines for medicine and for better crops for agriculture. Biotechnology has become a multibillion-dollar industry.
In view of the inexorable progress in science, we can expect that the gene hunters will be replaced in the spotlight. When and by whom? Which kind of hunter will dominate the scene in the last decade of our waning century and in the early decades of the next? I wonder whether the hunters who will occupy the spotlight will be neurobiologists who apply the techniques of the enzyme and gene hunters to the functions of the brain. What to call them? The head hunters. I will return to them later.
What is the main topic of the passage?
A. The progress of modern medical research
B. The discovery of enzymes
C. The potential of genetic engineering
D. The microbe hunters

Many factors influenced emerging modes of production. For example, machine tools, the tools used to make goods, were steadily improved in the latter part of the nineteenth century-always with an eye to speedier production and lower unit costs. The products of the factories were rapidly absorbed by the growing cities that sheltered the workers and the distributors. The increased urban population was nourished by the increased farm production that, in turn, was made more productive by the use of the new farm machinery. American agricultural production kept up with the urban demand and still had surpluses for sale to the industrial centers of Europe.
According to the passage, what was one effect of the improvement of machine tools?
A. More efficient transportation of natural resources
B. A reduction in industrial jobs
C. Lower manufacturing costs
D. Better distribution of goods

This frightening scenario is in part the consequence of a dramatic increase over the last quarter century in the development of once natural areas of wet marshland; home not only to frogs but to all manner of wildlife. Yet, there are no obvious reasons why certain frog species are disappearing from rainforests in the Southern Hemisphere which are barely touched by human hand. The mystery is unsett1ing to say the least, for it is known that amphibian species are extremely sensitive to environmental variations in temperature and moisture levels. The danger is that planet Earth might not only lose a vital link in the ecological food chain (frogs keep populations of otherwise pestilent insects at manageable levels), but we might be increasing our output of air pollutants to levels that may have already become irreversible. Frogs could be inadvertently warning us of a catastrophe.
What is best heading for the paragraph?
A. The mystery of amphibian decline.
B. Multi-coloured frog species cause problems
C. Frogs declining in number.
D. Frogs making changes to the ecosystem.

Read the text and answer the question.
People appear to be born to compute. The numerical skills of children develop so early and so inexorably that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impressive accuracy — one plate, oneknife, one spoon, one fork, for each of the five chairs. Soon they are capable of noting that theyhave placed five knives, spoons, and forks on the table and, a bit later, that this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction. It seems almost reasonable to expect that if a child were secluded on a desert island at birth and retrieved seven years later, he or she could enter a second-grade mathematics class without any serious problems of intellectual adjustment.
Of course, the truth is not so simple. This century, the work of cognitive psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped — or, as the case might be, bumped into — concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one. Psychologists have since demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed into finding the total. Such studies have suggested that the rudiments of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers — the idea of a oneness, a twoness, a threeness that applies to any class of objects and is a prerequisite for doing anything more mathematically demanding than setting a table — is itself far from innate.
With which of the following statements would the author be LEAST likely to agree?
A. Most people follow the same pattern of mathematical development.
B. Children naturally and easily learn mathematics.
C. Children learn to add before they
leam to subtract.
D. Mathematical development is subtle and gradual.
