1、考研英语(阅读)模拟试卷 33 及答案与解析Part ADirections: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)0 New Tools to Research EarthquakeOn December 16th, 1811, the residents of New Madrid, Missouri, were startled out of their beds by a huge earthquake, whic
2、h was quickly followed by a second. Those who survived the catastrophe reported that cracks opened in the earths surface, that the ground rolled visibly in waves and that large areas of land sank downwards. People in places as far away as Boston declared that they heard church bells ringing at the t
3、ime the earthquake happened.That huge earthquakes occur in parts of North America outside their traditional habitat on the Pacific margin is well known from accounts like those from New Madrid. Such records, however, have been kept only since Europeans arrived, so it has been hard to work out how ac
4、tive the faults that cause them are. Now it is a little easier. A study carried out by Samuel Panno of the Illinois State Geological Survey and his colleagues has revealed that nearby caves store the dates of past earthquakes in stone.Dr. Panno and his team found their recording angel in the form of
5、 stalagmites, the conical projections that grow on the floors of limestone caves. They made their discovery when using a radioactive dating technique to check the ages of small stalagmites occupying a number of caves in the Midwest. Many of these stalagmites had come into existence at about the same
6、 moment, and that moment coincided with the New Madrid earthquake.This makes sense. Stalagmites form when water trickles through crevices in a caves ceiling and drips to the floor. Each drop carries with it a quantity of dissolved calcium carbonate that it has picked up while flowing through the roc
7、k above. When a drop lands, some of this mineral is deposited at the landing site, where it accumulates, forming a stalagmite. A paper to be presented at a meeting of the Geological Society of America in Houston on October 5th by Dr. Pannos colleague Keith Hackley suggests that when large earthquake
8、s shake the ground, new cracks in cave ceilings open. The result is the formation of a new generation of stalagmites.Like trees, stalagmites are often composed of concentric layers that represent annual growth periods. Counting the layers is one way of assessing how old a stalagmite is. But radioact
9、ive dating provides a second, and sometimes more accurate, assessment.In this case the geologists drilled into the stalagmites and estimated their age from the way that uranium decays into an isotope of thorium. Many, they found, dated back to 1811, while others began life in 1917, the date of anoth
10、er nearby earthquake.Subsequent investigation has confirmed a further seven big earthquakes previously suspected to have happened over the course of the past 18, 000 years. An average interval between quakes of 2,500 years is a hopeful sign for New Madrids immediate future. But if the technique can
11、be tried out in other places it might reveal areas now thought safe, precisely because there has not been a recent earthquake, that are actually under threat.1 We can infer from the first two paragraphs that_.(A)a huge earthquake occurred on December 16th, 1811 in Spain(B) cracks opened in the earth
12、s surface in Boston during the quake(C) huge earthquakes in traditional habitat on the Pacific margin are famous(D)records concerning the quakes were not gathered until Europeans arrived2 The dates of past earthquakes are most probably stored in_.(A)angels(B) stalagmites(C) limestone caves(D)radioac
13、tive materials3 According to para. 4, what do people think of the technique concerning stalagmites?(A)Nonsense.(B) Believable.(C) Questionable.(D)Out-of-date.4 Which of the following is true according to para. 5?(A)Stalagmites are often composed of concentric tree layers that represent annual growth
14、 periods.(B) Counting the layers is the only way of assessing how old a stalagmite is up to now.(C) Radioactive dating is a more accurate assessment concerning the age of stalagmite.(D)With radioactive dating, age of stalagmite comes from the relation between uranium and thorium.5 Which of the follo
15、wing statement suits New Madrid the best in the immediate future?(A)There will only be huge earthquakes.(B) There will only be small earthquakes.(C) There will be both huge and small earthquakes.(D)There will be no huge earthquakes.5 How to Cope With the Bookstore Crisis ?These are not easy times fo
16、r booksellers. Borders, a big American one, ditched its boss in January and has closed stores, but is still at risk of collapse, some analysts say. The British chain of the same name, which it once owned, failed last year. Barnes if there were not five times as many blacks behind bars as whites, the
17、 figures would look even worse.There is no shortage of explanations for the gap. States with weaker labour markets, like South Carolina and Michigan, also tend to have larger black populations than low-unemployment states like Iowa and Montana. Predominantly black neighbourhoods are often a long way
18、 from where jobs are concentrated, in largely white suburbs, so those without cars cannot get to them. Blacks are also at a disadvantage when it comes to relying on friends and family connections to find jobs; there is not the same network of family businesses that whites and Latinos have. Some stud
19、ies have found that this factor may explain as much as 70% of the difference in black and white unemployment rates, and may also explain the difference between black and Latino jobless rates. Among young men, for instance, the near-20% Hispanic unemployment rate is much closer to that for whites (17
20、%)than blacks (30%). And discrimination, too, plays a part.What is clear is that the unemployment problem in black communities will not end with the recession. The employment-to-population ratio among black adults is only just above 50% , and it is closer to a shocking 40% for young black men; for a
21、dult whites it is 59 % . Black workers are also unemployed for about five weeks longer, on average, than the rest of the population. Some 45% of unemployed blacks have been out of work for 27 weeks or longer, compared with just 36% of unemployed whites. That means continued loss of skills, and a lon
22、ger and harder road back into the workforce.21 In the passage, the author mainly discusses about_.(A)the situation of a “post-racial“ America brought by Obama(B) the influence of racial discrimination on U.S. employment(C) the impact of the economic recession on U.S. employment(D)the employment gap
23、between blacks and whites in America22 What does the author mean by “mancession“ (Line 3, Para. 2)?(A)Gap between blacks and whites.(B) The rate of male employment.(C) The economic recession.(D)The male unemployment.23 According to the passage, the unemployment rate of the blacks might be higher if_
24、.(A)female blacks are counted in(B) there were more jailed blacks(C) the blacks in jail are counted in(D)well-educated blacks are included24 What is the main reason for the gap between black and white unemployment rates?(A)Blacks live far away from job concentrated places.(B) Most of blacks do not f
