Demands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe. Studies by the Council of Europe, of which 21 countries are members, have shown that 45 per cent of reptile(爬行的)species and 24 per cent of butterflies are in danger of dying out.

European concern for wildlife was outlined by Dr. Peter Baum, an expert in the environment and nature resources division of the council, When he spoke at a conference arranged by the administrators of a British national park. The park is one of the few areas in Europe to hold the council s diploma for nature reserves of the highest quality, and Dr. Baum had come to present it to the park once again. He was afraid that public opinion was turning against national parks, and that those set up in the 1960s and 1970s could not be set up today. But Dr. Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right.

No area could be expected to survive both as a true nature reserve and as a tourist attraction, he went on. The shortsighted view that reserves had to serve immediate human demands fur out door recreation should be replaced by full acceptance of their importance as places to preserve nature for the future. "We forget that they are the guarantee of life systems, on which any built-up area ultimately depends, "Dr. Baum went on, "We could manage without most industrial products, but we could not manage without nature. However, our natural environment areas, which are the original parts of our countryside, have shrunk to become mere islands in a spoiled and highly polluted land mass."

Recent studies by the Council of Europe show that _______.

A．it is only in Britain that wildlife needs more protection

B．certain species of reptiles and butterflies in Europe need protecting

C．there are fewer species of reptiles and butterflies in Europe than elsewhere

D．all species of wildlife in Europe are in danger of dying out

There is no denying that students should learn something about how computers work, just as we expect them at least to understand that the internal-combustion engine has something to do with burning fuel, expanding gases and pistons being driven. For people should have some basic idea of how the things that they use do what they do. Further, students might be helped by a course that considers the computer’s impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy; it is a trade skill that should not be taught as a liberal art. 　　Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers. But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun, and while our society needs some people who are experts at it, the same is true of auto repair and violin-making. 　　Learning how to use a computer is not that difficult, and it gets easier all the time as programs become more “user-friendly”. Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen. What does the phrase learning to use a computer mean? It sounds like “learning to drive a car", that is, it sounds as if there is some set of definite skills that, once acquired, enable one to use a computer. 　　In fact, “learning to use a computer” is much more like “learning to play a game”, but learning the rules of one game may not help you play a second game, whose rules may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program and generally that is easily accomplished. 1.To be the competent citizens of tomorrow, people should _______. 　A. try to lay a solid foundation in computer science 　B. be aware of how the things that they use do what they do 　C. learn to use a computer by acquiring a certain set of skills 　D. understand that programming a computer is more essential than repairing a car 2. In the second paragraph“auto repair”and“violin-making”are mentioned to show that ______. 　A. programming a computer is as interesting as making a violin 　B. our society needs experts in different fields 　C. violin making requires as much skill as computer programming 　D. people who can use a computer don’t necessarily have to know computer programming 3. Learning to use a computer is getting easier all the time because _______ . 　A. programs are becoming less complicated 　B. programs are designed to be convenient to users 　C. programming is becoming easier and easier 　D. programs are becoming readily available to computer users 4. According to the author, the phrase “learning to use a computer” (Lines3, 4, Para.3) means learning _______. 　A. a set of rules B. the fundamentals of computer science 　C. specific programs D. general principles of programming 5. The author’s purpose in writing this passage is _______. 　A. to stress the impact of the computer on society 　B. to explain the concept of computer literacy 　C. to illustrate the requirements for being competent citizens of tomorrow D. to emphasize that computer programming is an interesting and challenging job

A、summarizing the study

B、presenting the data

C、evaluating the study

D、deductions from the research

A rented out his house and courtyard facing the street to B, and B used it as an automobile repair shop. With A’s permission, B expanded, at his own expanses, several houses for automobile painting. When B was submitting an application to the authorities for expanding the building, he found that all the properties A rented out was not approved by the Urban Planning Department, meaning that all are unauthorized construction. Which of the following is true? A、 The lease contract is invalid. B、 A and B shall jointly bear the costs for expanded construction, because both are in fault in doing so. C、 B can cancel the lease contract, because A did not inform B that the house is unauthorized construction. D、 B can continue to perform the contract waiting for the relevant authorities to confirm that the house is unauthorized and affecting his use of the building, then he can claim for liability for breach of contract.
