　　Glacier National Park in Montana shares boundaries with Canada, an American Indian reservation, and a national forest. Along the North Fork of the Flathead River, the park also borders about 17,000 acres of private lands that are currently used for ranching, timber, and agriculture. This land is an important part of the habitat and migratory routes for several endangered species that frequent the park. These private lands are essentially the only ones available for development in the region.With encouragement from the park, local landowners initiated a land use planning effort to guide the future of the North Fork. The park is a partner in an inter local agreement that calls for resource managing agencies to work together and with the more than 400 private owners in the area. A draft plan has been prepared, with objective of maintaining traditional economic uses but limiting new development that would damage park resources. Voluntary action by landowners, in cooperation with the park and the county, is helping to restrict small lot subdivisions, maintain wildlife corridors, and minimize any harmful impact on the environment.

　　The willingness of local landowners to participate in this protection effort may have been stimulated by concerns that congress would impose a legislative solution. Nevertheless, many local residents want to retain the existing character of the area. Meetings between park officials and landowners have led to a dramatically improved understanding of all concerns.

　　1. The passage mainly discusses______.

　　A. the endangered species in Glacier National Park

　　B. the protection of lands surrounding Glacier National Park

　　C. conservation laws imposed by the state of Montana

　　D. conservation laws imposed by Congress

　　2. Why are the private lands surrounding Glacier National Park so important?

　　A. They function as a hunting preserve.

　　B. They are restricted to government use.

　　C. They are heavily populated.

　　D. They contain natural habitats of threatened species.

　　3. The relationship between park officials and neighboring landowners may best be described as______.

　　A. indifferent B. intimate?C. cooperative D. disappointing

　　4. It can be inferred from the passage that a major interest of the officials of Glacier National Park is to______.

　　A. limit land development around the park

　　B. establish a new park in Montana

　　C. influence national legislation

　　D. settle border disputes with Canada

　　答案解析：

　　1. B) 这是一道主旨题。通过阅读文章可知，为了保护冰川国家公园的濒危物种和资源，公园当局和地方土地所有者制订了限制土地使用计划，故答案为B。

　　2. D) 这是一道细节题。根据第一段第三句“This land is an important part of the habitat and migratory routes for several endangered species that frequent the park.”(这片土地是非常重要的'，因为这里是几种经常光顾此公园的濒危物种的栖息地和迁徙路线。)可知选项D为正确答案。

　　3. C) 根据第二段可知，公园当局和地方土地所有者密切合作来保护资源，因此他们的关系是"cooperative" (合作性的)。 ?

　　4. A) 这是一道推理题。根据第二段第三句和阅读全文，我们很容易就可以得到这样一个信息：为了保护自然资源和濒危物种，公园管理者限制那些会破坏资源的土地开发。因此选项A为正确答案。

　　People travel for a lot of reasons. Some tourists go to see battlefields or religious shrines. Others are looking for culture, or simply want to have their picture taken in front of famous places. But most European tourists are looking for a sunny beach to lie on.

　　Northern European are willing to pay a lot of money and put up with a lot if inconveniences for the sun because they have so little of it. Residents of cities like London, Copenhagen, and Amsterdam spend a lot of their winter in the dark because the days are so short, and much of the rest of the year in the rain. This is the reason the Mediterranean has always attracted them. Every summer, more than 25 million people travel to Mediterranean resort and beaches for their vacation. They all come for the same reason: sun!

　　The huge crowds mean lots of money for the economies of Mediterranean countries. Italy’s 30,000 hotels are booked solid every summer. And 13 million people camp out on French beaches, parks and roadsides. Spain’s long sandy coastline attracts more people than anywhere else. 37 million tourists visit yearly, or one tourist for every person living in Spain.

　　But there are signs that the area is getting more tourism than it can handle. The Mediterranean is already one of the most polluted seas on earth. And with increased tourism, it’s getting worse. The French can’t figure out what to do with all the garbage left by campers around St. Tropez. And in many places, swimming is dangerous because of pollution.

　　None of this, however, is spoiling anyone’s fun. The Mediterranean gets more popular every year with tourists. Obviously, they don’t go there for clean water and solitude. They tolerate traffic jams and seem to like crowded beaches. They don’t even mind the pollution. No matter how dirty the water is, the coastline still looks beautiful. And as long as the sun shines, it’s still better than sitting in the cold rain in Berlin, London, or Oslo.

　　1. The writer seems to imply that Europeans travel mostly for the reason that______.

　　A. they want to see historic remains or religious spots

　　B. they are interested in different cultural traditions and social customs

　　C. they would like to take pictures in front of famous sites

　　D. they wish to escape from the cold, dark and rainy days back at home.

　　2. In paragraph2，cities like London，Copenhagen，and Amsterdam are mentioned_____.

　　A. to show that they are not good cities in terms of geography and climate

　　B. to tell us how wealthy their residents are

　　C. to suggest that these cities lack places of historic interest and scenic beauty

　　D. to prove that they have got more tourism than they handle

　　3. According to the passage, which of the following countries attracts more tourists than the others?

　　A. Italy

　　B. Spain

　　C. Greece

　　D. France

　　4. The latter half of the last sentence in paragraph 3, “or one tourist for every person living in Spain”means _____.

　　A. all the 37 million people living in Spain are tourist

　　B. every year almost as many tourists visit Spain as there are people living in that country

　　C. every person living in Spain has to take care of a tourist

　　D. every Spanish is visited by a tourist every year

　　5. According to the passage, which of the following factors might spoil the tourists’ fun at Mediterranean resorts and beaches?

　　A. Polluted water.

　　B. Crowded buses.

　　C. Traffic jams.

　　D. Rainy weather.

　　答案解析

　　英语专四考试备考练习题 3

　　A controversy erupted in the scientific community in early 1998 over the use of DNA(deoxyribonucleic acid ) fingerprinting in criminal investigations.DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a pattern seen in their DNA,the molecule of which genes are made.DNA is present in every cell of the body except red blood cells.DNA fingerprinting has been used successfully in various ways,such as to determine paternity where it is not clear who the father of a particular child is.However,it is in the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.

　　DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to trove guilt,not just establish innocence.When used in criminal investigations,a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime.A match between the two DNA samples can be used as evidence to convict a suspect.

　　The controversy in 1998 stemmed form a report published in December 1991 by population geneticists Richard C.Lewontin of Harvard University in Cambridge,Mass.,and Daniel L.Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone.In particular,they argued that the current method cannot properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group.Lewontin and Hartl called for better surveys of DNA patterns methods are adequate.

　　In response to their criticisms,population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K.Kidd of Yale University in New Haven,Conn.,argued that enough data are already available to show that the methods currently being used are adequate.In January 1998,however,the federal Bureau of Investigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples form various ethnic groups in an attempt to resolve some of these questions.And,in April,a

　　National Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories.

　　1.Before DNA fingerprinting is used,suspects____.

　　A.would have to leave their fingerprints for further investigations

　　B.would have to submit evidence for their innocence

　　C.could easily escape conviction of guilt

　　D.cold be convicted of guilt as well

　　2.DNA fingerprinting can be unreliable when ____.

　　A.the methods used for blood- cell calculation are not accurate

　　B.two different individuals of the same ethnic group may have the same DNA fingerprinting pattern

　　C.a match is by chance left with fingerprints that happen to belong to two different individuals

　　D.two different individuals leave two DNA samples.

　　3.To geneticists like Lewontin and Hartl,the current method ____.

　　A.is not so convincing as to exclude the likelihood that two DNA samples can never come from two individuals

　　B.is arguable because two individuals of the same ethnic group are likely to have the same DNA pattern.

　　C.Is not based on adequate scientific theory of genetics

　　D.Is theoretically contradictory to what they have been studying

　　4.The attitude of the Federal Bereau of Investigation shows that ____.

　　A.enough data are yet to be collected form various ethnic groups to confirm the unlikelihood of two DNA samples coming from two individual members

　　B.enough data of DNA samples should be collected to confirm that only DNA samples form the same person can match

　　C.enough data are yet to be collected from various ethnic groups to determine the likelihood of two different DNA samples coming form the same person

　　D.additional samples from various ethnic groups should be collected to determine that two DNA samples are unlikely to come from the same person

　　5..National Academy of Sciences holds the stance that ____.

　　A.DNA testing should be systematized

　　B.Only authorized laboratories can conduct DNA testing

　　C.The academy only is authorized to work out standards for testing

　　D.The academy has the right to accredit laboratories for DNA testing

　　答案： CBABB
