When was the last time you saw a frog? Chances are, if you live in a city, you have not seen one for some time. Even in wet areas once teeming with frogs and toads, it is becoming less and less easy to find those slimy, hopping and sometimes poisonous members of the animal kingdom. All over the world, even in remote jungles on the far side of the globe, frogs are losing the ecological battle for survival, and biologists are at a loss to explain their demise. Are amphibians simply over-sensitive to changes in the ecosystem? Could their rapid decline in numbers be signalling some coming environmental disaster for us all?
Biologists are unable to explain why frogs are dying.

An example of a bizarre occurrence regarding a species of frog dates from the summer of 1995, when 'an explosion' of multi-coloured frogs of the species Rana klepton esculenta occurred in the Netherlands. Normally these frogs are brown and greenish-brown, but some unknown contributory factor is turning these frogs yellow and/or orange. Nonetheless, so far, the unusual bi- and even tri-coloured frogs are functioning similarly to their normal-skinned contemporaries. It is thought that frogs with lighter coloured skins might be more likely to survive in an increasingly warm climate due to global warming.
The species of Rana klepton esculenta are red and blue.

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.
The World Wide Web, an enormous collection of Internet addresses or sites, all of which can be accessed for information, has been mainly responsible for the increase in interest in the Internet in the 1990s. Before the World Wide Web, the 'Net' was comparable to an integrated collection of computerised typewriters, but the introduction of the 'Web' in 1990 allowed not only text links to be made but also graphs, images and even video. A Web site consists of a 'home page', the first screen of a particular site on the computer to which you are connected, from where access can be had to other subject related 'pages' at the site and to thousands of other computers all over the world. This is achieved by a process called 'hypertext'. By clicking with a mouse device on various parts of the screen, a person connected to the 'Net' can go travelling, or 'surfing' through a web of pages to locate whatever information is required.
Anyone can set up a site; promoting your club, your institution, your company's products or simply yourself, is what the Web and the Internet is all about. And what is more, information on the Internet is not owned or controlled by anyone organisation. It is, perhaps, true to say that no-one and therefore everyone owns the 'Net'. Because of the relative freedom of access to information, the Internet has often been criticised by the media as a potentially hazardous tool in the hands of young computer users. This perception has proved to be largely false however, and the vast majority of users both young and old get connected with the Internet for the dual purposes for which it was intended – discovery and delight.
Which is the best title for the passage ?
A. How to Use the Internet

Western people rely on technical and mechanical solutions in everything they do. Refrigerators preserve their food, washing machines clean their underwear and computers are supposed to solve all their problems. When they are ill, they rely on the surgeon’s knife. If their hearts are running down, then they must be repaired, if they cannot be repaired, they should be replaced, just as an old car sometimes gets a new engine. But up to now we have had a shortage of donors to give their hearts, to keep one person alive, another donor had to die.
Nowadays there is more and more talk about using monkeys. Every monkey has a near-human heart, and humans have always been over careful in respecting the lives and well-being of other animals. This includes the life and well-being of other humans. Therefore, in the early years of the 22nd century - It was told the mass killings of monkeys may occur. We’ll need to use their hearts for human consumption.
Monkeys, on the whole, are happier creatures than their near relatives, Homo sapiens, or man. They know fear, of course, and they face real dangers, but they are also more intelligent than us. They create no unnecessary dangers for themselves, they run no businesses, chase no money, are unimpressed by gold – that utterly useless metal, and they do not care at all about hell or evil spirits. I have a vague feeling that it is not monkeys’ hearts that we ought to implant in ourselves, but monkeys’ brains.
Monkeys are more stupid than humans because they always create unnecessary dangers for themselves…
A. TRUE
B. FALSE
C. NOT GIVEN

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 copy search results to a floppy disk, students pay…
A. a fee dependent on the time taken.
B. No fee
C. a fee based on actual costs.
D. $20

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.
The word "them" refers to
A. hormones
B. genes
C. gene hunters or genetic engineers
D. cells and plants
