News reports often focus on disputes among scientists over the validity of preliminary (untested) data, hypotheses, and models (which by definition are tentative). This aspect of science- 1 because it has not been widely 2 and accepted-is called frontier science. The media 3 to focus on frontier science because its so-called "breakthroughs" make good news stories. Just because something is in the 4 of frontier science, 5 , does not mean that it isn’’t worthy of serious consideration; 6 , such matters need further study to determine their 7 .    8 contrast, consensus science consists of data, models, theories, and laws that are widely accepted. This aspect of science is very reliable but is 9 considered newsworthy. The trouble is that the word science is used to 10 both frontier and consensus science, without 11 The media preference 12 frontier science gives the public the 13 impression that frontier science 14 very certain conclusions, which may or may not be correct.   However, 15 some frontier science is later shown to be unreliable, members of the public often falsely 16 that consensus science is also quite uncertain. We need to take both frontier and consensus science 17 but recognize their differences. One way to find out what scientists generally agree 18 is to seek out reports by scientific bodies that attempt to 19 consensus in 20 areas of science and technology.

Section Ⅱ Reading Comprehension Part A Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. (40 Points) Text 1 National characteristics are not easy to pin down, and when pinned down they often turn out to be trivialities or seem to have no connection with one another. Spaniards are cruel to animals; Italian can do nothing without making a deafening noise; the Chinese are addicted to gambling. Obviously such things don’t matter in themselves. Nevertheless, nothing is causeless, anti even the fact that Englishmen have bad teeth can tell one something about the realities of English life. Here are a couple of generalizations about England that would be accepted by almost all observers. One is that the English are not gifted artistically. They are not as musical as the Germans or Italians; painting and sculpture have never flourished in England as they have in France. Another is that, as Europeans go, the English are not intellectual. They have a horror of abstract thought; they feel no need for any philosophy or systematic ‘world-view’. Nor is this because they are ’practical’, as they are so fond of claiming for themselves. One has only to look at their methods of town planning and water supply, their obstinate clinging to everything that is out of date and a nuisance, a spelling system that defies analysis and a system of weights and measures that is intelligible only to the compilers of arithmetic books, to see how little they care about mere efficiency. Another English characteristic which is so much a part of us that we barely notice it, is the addiction to hobbies and spare-time occupations, the privateness of English life. We are a nation of flower-lovers, but also a nation of stamp-collectors, pigeon-fanciers, amateur carpenters, coupon- snipers, darts-players, crossword-puzzle fans. All the culture that is most truly native centers round things which even when they are communal are not official -- the pub, the football match, the back garden, the fireside and the ‘nice cup of tea’. The liberty the individual is still believed in, almost as in the nineteenth century. But this has nothing to do with economic liberty, the right to exploit others for profit. It is the liberty to have a home of your own, to do what you like in your spare time, to choose your own amusements instead of having them chosen for you from above.

From the first paragraph, we can learn that()

A:Chinese are indulged in gambling. B:you are likely to encounter cruel animals in Spain. C:whenever an Italian does anything, he will keep a stiff upper lip. D:to summarize one people’s characteristics, one must understand their culture.

To summarize Grice’s ideas in the light of other linguists’ elaborations, characteristics of irnplicature includes ().

A:calculability B:cancellability C:non-detachability D:conventionality

Climate Change Poses Major Risks for Unprepared Cities

? ?A new examination of urban policies has been ?(51) ? recently by Patricia Romero Lankao. She is a sociologist specializing in climate change and urban development. She warns that many of the world’s fast-growing urban areas, especially in developing countries, will likely ?(52) ? the impacts of changing climate. Her work also concludes ?(53) ? most cities are failing to reduce emissions of carbon dioxide and other greenhouse gases. These gases are known ?(54) ? affect atmosphere. "Climate changes a deeply local issue and poses profound threats to the growing cities of the world," says Romero Lankao. "But ?(55) ? cities are developing effective strategies to protect their residents. "
? ?Cities are ?(56) ? sources of greenhouse gases. And urban populations are likely to be among those most severely affected by future climate change. Lankao’s findings ?(57) ? ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term benefits.
? ?The locations and dense construction patterns of cities often place their populations at greater. ?(58) ? for natural disasters. Potential threats associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat ?(59) ? paved cities more than surrounding areas. The impacts of such natural events can be more serious in an urban environment. ?(60) ?, a prolonged heat wave can increase existing levels of air pollution, causing widespread health problems. Poorer neighborhoods that may lack basic facilities such as drinking water or a dependable network of roads, are especially vulnerable to natural disasters. Many residents in poorer countries live in substandard housing without ?(61) ? reliable drinking water, roads and basic services.
? ?Local governments, ?(62) ? , should take measures to protect their residents. "Unfortunately, they tend to move towards rhetoric rather than meaningful responses," Romero Lankao writes. "They don’t impose construction standards that could reduce heating and air conditioning needs. They don’t emphasize mass transit and ?(63) ? automobile use. In fact, many local governments are taking a ?(64) ? approach. " Thus, she urges them to change their idle policies and to take strong ?(65) ? to prevent the harmful effects of climate change on cities.
