Despite improvements in treatment for asthma, the death rate from this disease has doubled

during the past decade from its previous rate. Two possible explanations for this increase have been offered. First, the recording of deaths due to asthma has become more widespread and accurate in the past decade than it had been previously. Second, there has been an increase in urban pollution. However, since the rate of deaths due to asthma has increased dramatically even in cities with long-standing, comprehensive medical records and with little or no urban pollution, one must instead conclude that the cause of increased deaths is the use of bronchial inhalers by asthma sufferers to relieve their symptoms. Each of the following, if true, provides support to the argument EXCEPT:

A.Urban populations have doubled in the past decade.

B.Records of asthma deaths are as accurate for the past twenty years as for the past ten years.

C.Evidence suggests that bronchial inhalers make the lungs more sensitive to irritation by airborne pollen.

D.By tem|X)rarily relieving the symptoms of asthma, inhalers encourage sufferers to avoid more beneficial measures.

E.Ten years ago bronchial inhalers were not available as an asthma treatment.

听力原文:Despite various improvements in all aspects of social life, the generation gap be

听力原文: Despite various improvements in all aspects of social life, the generation gap between the grown-up and young remains unbridged. Instead, it grows wider apart.

Nowadays, the youths do not blindly follow what their elders say. Owing to the widespread of education, the influence of western civilization, to a certain extent, gives them a new code of philosophy, which is completely different from that of their elders. An invisible cold wall thus appears between the two generations.

Modern youths are trying to be more revolutionary. They have their own interpretation for different matters; they also have their own ideals. Their reluctance to learn old teachings and sayings becomes the constant friction between the two generations. They always introduce new changes. However, the old people, wedded to everything of the past, are hostile to changes and the generation gap becomes wider and wider.

After all, the young generation, like the old one, is made of flesh and blood. The young also need respect and they also have skills and good ideas. In order to narrow the gap, both groups should respect each other, listen to the words of each other. Most probably, these may help to solve the problem.

(23)

A.Generation gap.

B.Modem youths.

C.Influence of western civilization.

D.Social improvements.

Despite the road improvements of the turnpike era(1790—1830), Americans continued as in co

Despite the road improvements of the turnpike era(1790—1830), Americans continued as in colonial times to depend wherever possible on water routes for travel and transportation. The larger rivers, especially the Mississippi and the Ohio, became increasingly useful as steamboats grew in number and improved in design.

River boats carried to New Orleans the corn and other crops of northwestern farmers, the cotton and tobacco of southwestern planters. From New Orleans, ships took the cargoes on to eastern sea ports. Neither the farmers of the west nor the merchants of the east were completely satisfied with this pattern of trade. Farmers could get better prices for their crops if the alternative existed of sending them directly eastward to market, and merchants could sell larger quantities of their manufactured goods if these could be transported more directly and more economically to the west.

New waterways were needed. Sectional jealousies and constitutional scruples stood in the way of action by the federal government, and necessary expenditures were too great for private enterprise. If extensive canals were to be dug, the job would be up to the various states.

New York was the first to act. It had the natural advantage of a comparatively level route between the Hudson River and Lake Erie, through the only break in the Appalachian Mountain chain. Yet the engineering tasks were imposing. The distance was more than 350 miles, and there were ridges to cross and a wilderness of woods and swamps to penetrate. The Erie Canal, begun in 1817 and completed in 1825, was by far the greatest construction job that Americans had ever undertaken. It quickly proved a financial success as well. The prosperity of the Erie encouraged the state to enlarge its canal system by building several branches.

The range of the New York canal system was still further extended then the states of Ohio and Indiana, inspired by the success of the Erie Canal, provided water connections between Lake Erie and the Ohio River.

What does the passage suggest was the principal route for transporting crops to the east prior to 12?

A.River to road

B.Canal to river

C.River o ocean

D.Road to canal

Primary school teachers' poor 【C1】______ of English and maths is undermining the Governmen
t's literacy and numeracy strategies, an official evaluation has concluded.

【C2】______ in teachers' knowledge of their subject and weaknesses in their teaching methods are threatening to limit improvements in reading, writing and numeracy, the analysis for the Department for Education and Skills found.

The report, 【C3】______ a team of academics from Toronto University, concluded that it was difficult to assess the effect of the 【C4】______ on pupils' learning. While literacy and numeracy scores had risen significantly between 1997 and 2002, much of the increases had 【C5】______ before the introduction of the two strategies: literacy in 1998 and numeracy in 1999.

The team, led by Professor Michael Fullan, also warned ministers against 【C6】______ ever higher targets for schools, arguing that this would backfire when staff began to regard the goals as 【C7】______ .

But this advice came too late for the Government, which has already set new and higher targets for primary schools, 【C8】______ failing to meet the previous goals in the summer.

Soon after coming to power in 1997, the Labour government set challenging targets which required 80 percent of Il-year-olds to reach a required 【C9】______ in English, and 75 percent in maths, by 2002. But after a strong start, the improvements tailed off and both 【C10】______ were missed.

Despite this failure, ministers have repeated their desire to push ahead with more demanding goals that require 85 percent of students to reach the standard in English and maths by 2004.

The team of academics highlighted the 【C11】______ of some primary teachers' knowledge. "For the strategies to succeed in the ways that strategy leaders believe 【C12】______ possible, many teachers will need to be highly skilled and more knowledgeable about teaching literacy and mathematics than is currently the case," the report said.

"The data indicate that for many teachers, gaps or weaknesses in subject knowledge limit the extent 【C13】______ they can make full use of the frameworks and resources of the strategies." The 【C14】______ also said that the high-profile nature of the targets had had "unintended negative consequences" for primary schools.

The team cast 【C15】______ on ministers' ambition to improve standards further. The pressure on teachers to comply with directives from central government threatened to create a "culture of dependence" that would make it difficult for schools to raise standards once the ministers' focus had moved, the report concluded.

【C1】

A.grasp

B.grip

C.hold

D.concern

听力原文: Ask any kid about homework, and you'll get the same response: There is too much of it, and too much of it is worthless.

Ah, kids. What do they know?

Maybe more than you think.

The push 'for high standards in American education has driven schools to pile on the homework. Twenty years ago elementary school children averaged 85 minutes of homework a night, according to a University of Michigan study. Today that's grown to more than two hours a night, a 50 percent increase.

That's not the only thing that's grown. So have the number of children who report having back, shoulder and neck pain as a result of hauling back packs heavy with homework, according to the American Academy of Orthopedic Surgeon.

Results are mixed. The U.S. Department of Education tests progress in math, reading and science under a program called the National Assessment of Educational Progress. And in the twenty years, while fourth-graders have made moderate improvements in math and science, reading scores actually have declined slightly.

Junior and senior high students have made better gains in test scores. But despite that, a vocal anti-homework movement has emerged the last few years that argues that too much homework takes away from important family time and actually creates a counterproductive backlash in some students who simply get tired of the grind. What's more, they argue, few studies have established any concrete benefits to heavy homework loads.

(33)

A.It has doubled.

B.It has increased by half.

C.It has an 85% growth.

D.It has grown out of proportion.

To: Jakob Skolnik

From: Victoria Williams

Subject: yesterday's awards ceremony

Mr. Skolnik,

We were all concerned about your sudden illness yesterday and hope that you are feeling better today. I know that you will feel reassured to learn that last night's awards ceremony went very well despite your absence. We had Kazadi Koite lead both items 3 and 4, and I am happy to report that he did an excellent job. The CEO of B. J. Technology accepted the award for "most environmentally friendly company" on his company's behalf and expressed great delight on receiving it. The reception was enjoyed by all. We had reserved the room for only three hours, and some guests stayed until the last possible moment. More guests attended than we expected, so we barely had enough room for everyone. Perhaps we should ask for a bigger room next year. Rooms 2 and 3 are also small, but either room 4 or room 6 would be a good size, think. Even though the ceremony and reception were a great success, I have several other ideas for improvements for next year's ceremony. We can discuss them when you return to work. Please rest well. We hope to see you healthy and back at work soon.

Victoria

Passage Three:Questions 21 to 25 are based on the following passage.After the violent eart
hquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll (死亡人数) could have been much worse.

More than 60 people died in this earthquake. By comparison, as earthquake of similar intensity that shook America in 1988 claimed 25,000 victims.

Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a.m. on a holiday, when traffic was light on the city’s highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city’s buildings and highways, making them more resistant to quakes.

Despite the good new, civil engineers aren’t resting on their successes. Pinned to their drawing boards are blueprints (蓝图) for improved quake-resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place.

In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports. Called smart buildings, the structures respond like living organisms to an earthquake’s vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction.

The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

第21题:One reason why the loss of lives in the Los Angeles earthquake was comparatively low is that ________.

A) new computers had been installed in the buildings

B) it occurred in the residential areas rather than on the highways

C) large numbers of Los Angeles residents had gone for a holiday

D) improvements had been made in the construction of buildings and highways

阅读理解:Robert F. Kennedy once said that a country's GDP measures "everything except that which

Robert F. Kennedy once said that a country's GDP measures "everything except that which makes life worthwhile." With Britain voting to leave the European Union, and GDP already predicted to slow as a result, it is now a timely moment to assess what he was referring to.

The question of GDP and its usefulness has annoyed policymakers for over half a century. Many argue that it is a flawed concept. It measures things that do not matter and misses things that do. By most recent measures, the UK's GDP has been the envy of the Western world, with record low unemployment and high growth figures. If everything was going so well, then why did over 17 million people vote for Brexit, despite the warnings about what it could do to their country's economic prospects?

A recent annual study of countries and their ability to convert growth into well-being sheds some light on that question. Across the 163 countries measured, the UK is one of the poorest performers in ensuring that economic growth is translated into meaningful improvements for its citizens. Rather than just focusing on GDP, over 40 different sets of criteria from health, education and civil society engagement have been measured to get a more rounded assessment of how countries are performing.

While all of these countries face their own challenges , there are a number of consistent themes . Yes , there has been a budding economic recovery since the 2008 global crash , but in key indicators in areas such as health and education , major economies have continued to decline . Yet this isn't the case with all countries . Some relatively poor European countries have seen huge improvements across measures including civil society , income equality and the environment.

This is a lesson that rich countries can learn : When GDP is no longer regarded as the sole measure of a country's success, the world looks very different .

So, what Kennedy was referring to was that while GDP has been the most common method for measuring the economic activity of nations , as a measure , it is no longer enough . It does not include important factors such as environmental quality or education outcomes - all things that contribute to a person's sense of well-being.

The sharp hit to growth predicted around the world and in the UK could lead to a decline in the everyday services we depend on for our well-being and for growth . But policymakers who refocus efforts on improving well-being rather than simply worrying about GDP figures could avoid the forecasted doom and may even see progress .

1.Robert F. Kennedy is cited because he

A.praised the UK for its GDP

B.identified GDP with happiness

C.misinterpreted the role of GDP

D.had a low opinion of GDP

2.It can be inferred from Paragraph 2 that

A.the UK is reluctant to remold its economic pattern

B.GDP as the measure of success is widely defied in the UK

C.the UK will contribute less to the world economy

D.policymakers in the UK are paying less attention to GDP

The Evolution of the PhotofitSecurity technology: A new type of computerised photofit syst

The Evolution of the Photofit

Security technology: A new type of computerised photofit system takes a novel evolutionary approach to generating images of suspects. If you have ever tried to describe someone's face in detail, you will understand why the "photofit" composite images used by the police look so dodgy. In recent years, computerised "E-Fit" systems have helped improve the accuracy of these images by allowing witnesses to choose from a wider range of facial features. But researchers at the University of Stirling in Scotland found that, despite these improvements, people still have a hard time constructing recognisable faces--especially if there is a delay of more

The problem is that people tend to recoguise faces as whole entities, rather than as separate features. So picking from a range of eyes, noses and mouths is not necessarily the most suitable approach, says Charlie Frowd, a psychologist at the University of Stifling. Next year, however, British police are expected to begin trials of a new computerised system, called EvoFIT, developed by Dr. Frowd and his colleague Peter Hancock. It uses an evolutionary approach, known as a genetic algorithm, to "evolve" faces rather than piece them together.

"The process is entirely non-verbal and takes a fraction of the normal time," claims Dr. Frowd. A witness is shown an array of 60 different faces with random features. Having studied them closely, the witness is asked to choose the six images that most closely resemble the person they are trying to describe. These six are then used to generate another set of 60, by switching featurees between some of the images and by making random changes to others. The witness is then asked to repeat the task, whereupon a new batch of faces is generated, and so on. In evolutionary terms, this process is known as "genetic crossover and mutation", and is a powerful way to search a large number of possibilities for a particular solution. By allowing the user to steer the selection process, the program is able to generate a good likeness for the original face after just a few cycles.

In one of its early versions, EvoFIT was used by police in Northampton shire who were trying to catch a violent attacker. The attacker was never caught, but the senior investigating officer, Superintendent Paul Spick, says the witness involved found the new software much quicker and easier to use than traditional E-Fit systems. It was also more accurate: the final image caused the witness visible distress when displayed. A further important advantage of EvoFIT over traditional composites is that an image can be generated even if the witness can only provide a sketchy verbal description.

The researchers have since made a number of further improvements to their system and are now in the process of commercializing it in partnership with ABM, a British firm which supplies police forces with photofit, one of the leading computerized composite systems. The images are more realistic, and the system can generate three-quarter angle views of the face, which are easier to distinguish than direct frontal views, says Dr. Frowd.

A His team has also found that by combining the images generated by different witnesses, or even from a single witness, it is possible to get an even better likeness. B This could be particularly useful when multiple witnesses come forward and the police are unsure which of the images they produce is the most accurate. C In the latest version, witnesses are given a selection of face shapes to choose from before facial features are added. D This makes it less likely that the correct facial features will be rejected simply because they are on the wrong-shaped face.

These modifications appear to make all the difference. In recent experiments, Dr. Frowd and Dr. Hancock compared EvoFIT with the computerized systems currently in use by asking volunteers

A.mixture.

B.compose.

C.find.

D.system.
