1、自考英语（二）模拟试卷 43 及答案与解析一、阅读判断0 American SportsThe United States is a sports-loving nation. Sports in America take a variety of forms; organized competitive struggles, which draw huge crowds to cheer their favorite team to victory; athletic games, played for recreation anywhere sufficient space is foun

2、d; and hunting and fishing. Most sports are seasonal, so that what is happening in sports depends upon the time of year. Some sports are called spectator sports, as the number of spectators really exceeds the number playing in the game.Baseball is the most popular sport in the US. It is played throu

3、ghout the spring and summer, and professional baseball teams play well into the fall. Although no other game is exactly like baseball, perhaps the one most nearly like it is the English game of cricket(板球).Football is the most popular sport in the fall. The game originated as a college sport more th

4、an 75 years ago. It is still played by almost every college and university in the country, and the football stadiums of some of the largest universities seat as many as 80,000 people. The game is not the same as European football or soccer. In American football there are 11 players on each team, and

5、 they are dressed in padded uniforms and helmets because the game is rough and injuries are likely to occur.Basketball is the winter sport in American schools and colleges. Like football, basketball originated in the US and is not popular in other countries. Many Americans prefer it to football beca

6、use it is played indoors throughout the winter and because it is a faster game. It is a very popular game with high schools, and in more than 20 states, state-wide high school matches are held yearly.Other spectator sports include wrestling, boxing, and horse racing. Although horse-racing fans call

7、themselves sportsmen, the accuracy of the term is questionable, as only the jockeys (骑师) who ride the horses in the races can be considered athletes. The so-called sportsmen are the spectators, who do not “assemble“ (聚集)primarily to see the horses race, but to bet upon the outcome of each race. Gamb

Enzyme (酶) systems

12、 of mammals and birds are most efficient only within a narrow range around 37 ; a departure of a few degrees from this value seriously impairs their functioning. Even though cells can survive wider fluctuations, the integrated actions of bodily systems are impaired. Other animals have a wider tolera

13、nce for changes of bodily temperature.For centuries it has been recognized that mammals and birds differ from other animals in the way they regulate body temperatures. Ways of characterizing the difference have become more accurate and meaningful over time, but popular terminology still reflects the

14、 old division into “warm-blooded“ and “cold-blooded“ species; warm-blooded included mammals and birds, whereas all other creatures were considered cold-blooded. As more species were studied, it became evident that this classification was inadequate. A fence lizard or a desert iguana (鬣蜥)each cold-bl

15、oodedusually has a body temperature only a degree or two below that of humans and so is not cold. Therefore the next distinction was made between animals that maintain a constant body temperature, called homotherms (同温动物) ,and those whose body temperature varies with their environment, called poikil

16、otherms (变温动物). But this classification also proved inadequate, because among mammals there are many that vary their body temperatures during hibernation. Furthermore, many invertebrates (无脊椎动物) that live in the depths of the ocean never experience a change in the chill of the deep water, and their

17、body temperatures remain constant.The current distinction is between animals whose body temperature is regulated chiefly by internal metabolic processes and those whose temperature is regulated by, and who get most of their heat from, the environment. The former are called endotherms (恒温动物) ,and the

18、 latter are called ecto-therms (外温动物).Most ectotherms do regulate their body temperature, and they do so mainly by locomoting to favorable sites or by changing their exposure to external sources of heat. Endotherms (mainly mammals and birds) also regulate their temperature by choosing favorable envi

19、ronments, but primarily they regulate their temperatures by making a variety of internal adjustments. 11 The passage mainly discusses_.（A）body temperatures of various animals（B） the newest research on measuring temperature（C） methods of temperature reduction（D）the classification of animals by temper

20、ature regulation12 Which of the following terms refers primarily to mammals and birds?（A）Warm-blooded.（B） Ectothermic.（C） Cold-blooded. D, Poikilothermic.13 In general, the temperature of endotherms is regulated _.（A）consciously（B） internally（C） inadequately（D）environmentally14 According to the pass

21、age, the chief way in which ectotherms regulate their temperature is by_.（A）seeking out appropriate locations（B） hibernating part of the year（C） staying in deep water（D）triggering certain metabolic processes15 According to the passage, human beings mainly regulate their body temperatures by_.（A）choo

22、sing favorable environments（B） internal metabolic processes（C） eating more food（D）doing physical exercises三、概括段落大意和补全句子15 The Weight ExperimentNicola Waiters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a “calorimete

23、r“ (热量测量室) is one way to find out.The signs above the two rooms read simply “Chamber One“ and “Chamber Two“. These are the calorimeters: 4 m by 2 m white-walled rooms where human volunteers are locked up in the name of science. Outside these rooms another sign reads “Please do not enterwork in progr

24、ess“ and in front of the rooms advanced machinery registers every move the volunteers make. Each day, meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer.Nicola Waiters is one of twenty volunteers who, over the past eight months, have sp

25、ent varying periods inside the calorimeter. Tall and slim, Nicola does not have a weight problem, but thought the strict diet might help with her training and fitness program. A self-employed community dance worker, she was able to fit the experiment in around her work. She saw an advert for volunte

26、ers at her local gym and as she is interested in the whole area of diet and exercise, she thought she would help out.The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room. This sequence was repeated four times over six weeks. She arrived at the calor

27、imeter at 8:30a. m. on each of the four mornings and from then on everything she ate or drank was carefully measured. Her every move was noted too, her daily exercise routine timed to the last second. At regular intervals, after eating, she filled in forms about how hungry she felt and samples were

28、taken for analysis.The scientists help volunteers impose a kind of order on the long days they face in the room. “The first time, I only took one video and a book, but it was OK because I watched TV the rest of the time,“ says Nicola. And twice a day she used the exercise bike. She pedaled (踩踏板) for

29、 half an hour, watched by researchers to make sure she didnt go too fast.It seems that some foods encourage you to eat more, while others satisfy you quickly. Volunteers are already showing that high-fat diets are less likely to make you feel full. Believing that they may now know what encourages pe

According to the Endangered Species Act, an endangered species is an animal that is likely to face extinction in its natu

34、ral habitat.【T1】_ The ESA defines a threatened species as one that is likely to become “endangered“ in the foreseeable future.The polar bear is the first animal that has been classified as endangered due primarily to global warming.【T2】_ Heating homes, driving cars, and burning garbage all require f

35、ossil fuels that lead to global warming.The polar bears habitat is more vulnerable to global warming than many other species. Polar bears live mainly on the sea ice in the Arctic.【T3】_ When the ice melts many polar bears move to land and live off their stored fat. In the Arctic, global warming is ca

36、using the ice to melt slightly earlier and form slightly later. This results in a shorter feeding season for the polar bear. Some risk their lives to find ice. If they have to swim too far they will drown from exhaustion and hunger.【T4】_ Every species of plant, animal, and insect there is threatened

37、 by global warming. Nevertheless, environmentalist groups such as the World Wildlife Fund often study large carnivores in order to assess the health of an ecosystem (生态系统).【T5 】_ In addition, donations are more commonly offered for the protection of large animals such as bears or elephants. People i

38、n general are less interested in conservation efforts that protect small wildlife, such as plants or insects. However, by using donor money to protect the habitat of the larger animals (ex. reforestation programs), entire ecosystems can be protected.It is important that animals such as the polar bea

39、r make it onto the endangered species list.Once they are on the list there are laws that protect these animals from being hunted for food or sport. Agencies also receive money and tools to protect the habitat and recover the species. The goal of removing the animal from the list is often achievable.

40、 In fact, it is rare for a species to go extinct after they make the list. Sadly many species do go extinct while waiting for consideration.A. But adding polar bears to the nations list of endangered species, as some are now proposing, should not be part of those efforts.B. Global warming is caused

41、by carbon dioxide and other greenhouse gases that become trapped in the atmosphere.C. The Arctic food chain relies on the polar bear.D. It is not only the polar bear that is at risk in the Arctic.E. This is where they hunt for fish and build up fat reserves.F. Polar bears have been categorized as a
