The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.

　　Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.

　　For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.

III. Reading Comprehension     
Section A
Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D.  Fill in each blank with the word or phrase that best fits the context.
Your cell phone holds secrets about you. Besides the names and   50   that you’ve programmed into it, traces of your DNA remain on it, according to a new study.
　　DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you   51   you have an identical twin. Scientists today routinely analyze DNA in blood, saliva (唾液), or hair   52   behind at the scene of a crime. The results often help detectives identify   53   and their victims. Your cell phone can   54   more about you than you might think.
　　Meghan J. McFadden, a scientist at McMaster University1in Hamilton, Ontario, heard about a crime in which the suspect（嫌疑犯）bled onto a cell phone and later dropped the   55  . This made her wonder whether traces of DNA remained on cell phones ___ even when no blood was involved.　    56   she and colleague Margaret Wallace of the City University of New York analyzed the flip-open phones(翻盖手机) of 10 volunteers. They used swabs(药签) to collect   57   traces of the users from two parts of the phone: the outside, where the user holds it, and the   58  , which is placed at the user’s ear.
The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to   59   all detectable (可查明的) traces of DNA. The owners got their phones back for another week.   60   the researchers collected the phones and repeated the swabbing of each phone once more.
The scientists discovered DNA that   61   to the phone’s owner on each of the phones. Better samples were collected from the outside of each phone, but those swabs also   62    DNA of other people who had apparently also handled the phone.   63  , DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won’t remove all traces of evidence from a criminal’s device. So cell phones can now be added to the   64   of clues that can settle a crime-scene investigation.

　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 (爬行动物) species and 24 per cent of butterflies are in danger or dying out.

　　European concern for wildlife was outlined by Dr Peter Baum, an expert in the environment and natural 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 for outdoor 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 (保证) of life systems, on which any built-up area 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 become mere islands in a spoiled and highly polluted land.”

59. Recent studies by the Council of Europe have declared that ____ .

　A. wildlife needs more protection only in Britain

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

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

　D. many species of reptiles and butterflies in Europe need protecting

60. Why did Dr Baum come to a British national park?

　A. Because he needed to present it with a council's diploma.

　B. Because he was concerned about its management.

　C. Because it was the only national park of its kind in Europe.

　D. Because it was the only park that had ever received a diploma from the council.

61. The last sentence in the second paragraph implies that ____ .

　A. people should make every effort to create more environment areas

　B. people would go on protecting national parks

　C. certain areas of the countryside should be left intact (完整的)

　D. people would defend the right to develop the areas around national parks

62.Which of the following can be inferred from the last paragraph?

　A. We have developed industry at the expense of countryside.

　B. We have forgotten what our original countryside looked like.

　C. People living on islands should protect natural resources for their survival.

　D. We should destroy all the built-up areas.
