More than 1.5 billion people around the world live without electricity. Finding better ways to bring light to the poor is the goal of researchers like Professor Irvine. In the late 1990s, he was working in Nepal when his return flight was canceled. A delay gave him time to take a fourteen-day hiking trip in the Himalayas.
One day he looked in the window of a school and noticed how dark it was. This is a common problem for millions of children around the world. Many families use kerosene oil (煤油) lamps. There are many problems with these lamps. They produce only a small amount of light. They are dangerous to breathe. And they are a big fire danger, causing many injuries and deaths each year. Kerosene costs less than other forms of lighting, but it is still costly in poor countries. Professor Irvine says many people spend over 100 dollars a year on the fuel.
When he returned to Canada, he began researching ways to provide safe and clean lighting. He began experimenting with light-emitting diodes (发光二极管), LEDs, at his lab. As a professor of renewable energy, he already knew about the technology. Light-emitting diodes are small glass lamps that use much less electricity than traditional bulbs (灯泡) and last much longer. He used a one-watt bright white LED made in Japan. He found it on the Internet and connected it to a bicycle-powered generator (发电机). He remembers thinking it was so bright that a child could read by the light of a single diode.
In 2000, after much research and many experiments, he returned to Nepal to put the systems into homes. Now the homes of 25,000 people in 51 countries have been equipped with it. “The one-time cost of our system which basically lives forever, as well as the solar panel — is less than one hundred dollars. So, one year of kerosene would pay for a solid-state lighting system,” he said. Now his aim is to develop a lower-cost lighting system. In January, Irvine is leaving the University of Calgary. He has also decided to start his own company in India.
1.We can learn from the second paragraph that kerosene oil lamps ______.
A. cost more than other forms of lighting
B. have damaged children’s eyesight
C. have wasted only a little fuel
D. have a lot of disadvantages
2.Irvine connected a white LED to a bicycle-powered generator to prove ______.
A. whether it can work without electricity
B. whether it can work well with less electricity
C. whether it can last longer than a generator
D. whether it is brighter than a traditional bulb
3.We can learn from the text that Irvine ______.
A. likes India rather than Nepal
B. is good at making new kinds of bulbs
C. is giving up his job in the university
D. is to earn much money from his company

Paris has grown steadily since it was chosen as the national capital in the late 10th century. With the introduction of the Industrial Revolution, a great number of people moved to the city from the country during the 19th century. The migration(移居) was especially stimulated(增强) by the construction of railroads, which provided easy access(通路) to the capital. After World War II more and more immigrants(移民) arrived.

第三部分 阅读理解(共20小题:每小题2.5分,满分50分)
阅读下列短文,从每题所给的四个选项A、B、C、D四个选项中,选出最佳选项。
Today, as in every other day of the year, more than 3000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death.
Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised.
First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors exceeded that among female by nearly 10 percent. The statistic is reversing. Third, several recent studies have indicated high school dropouts have excessively high smoking rates, as much as 75 percent.
Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking levels among youth.
36. According to the author, the deaths among youth are mainly caused by __________.
A. traffic accidents B. smoking-related disease
C. murder D. all of these
37. Every day there are over ______ high school students who will become regular smokers.
A. 750 B. 23 C. 30 D. 3000
38. By “dropout” the author means __________.
A. students who failed the examination B. students who left school
C. students who lost their way D. students who were driven out of school
39. The reason for declining adolescent smoking is that __________.
A. NCI has taken effective measures
B. smoking is prevented among high school seniors
C. there are many smokers who have died of cancer
D. none of these
40. What is implied but not stated by the author is that __________.
A. smoking rates among youth have declined very little
B. there are now more female than male smokers among high school seniors
C. high smoking rates are due to the increase in wealth
D. smoking at high school is from low socio-economic backgrounds

We often use the words “growth” and “development” as if they meant basically the same thing. But this may not always be the case. One can easily imagine instances in which a country has achieved higher levels of income (growth) with little or no benefit coming to most of its citizens (development).
In the past, most development policies were aimed at increasing the growth rate of income per capita (人均所得). Many are still based on the theory that benefit of economic growth will come to all members of society. If this theory is correct, growth should encourage development.
By the early 1970s, however, the relationship between growth and development was being questioned. A major study by the World Bank in 1974 concluded that it is now clear that more than decades of rapid growth in developing countries has been of little benefit to & third of their population.
The World Bank study showed that increase in GNP per capita did not promise important improvements in such devel??opment indicators as nutrition (营养), health, and education. Although GNP per capita did indeed rise, its benefit came down to only a small part of the population. This realization gives rise to a call for new development policies. These new policies favor agriculture over industry, call for national redis??tribution (资源分配) of income and wealth, and encourage programs to satisfy such basic needs as food and shelter.
In the late 1970s and early 1980s the international macroeconomic crises (大规模的经济危机) of high oil prices, worldwide recession (衰退) and the third world debt, forced attention away from programs designed to get rid of poverty. however, the lesson remains: economic growth does not prom??ise economic development. Efforts may be required to change growing output capacity (能力) into economic benefit that reach most of a nation’s people.
What do we learn from the first paragraph about the relationship between growth and development?
A. Growth and development refer to the same thing.
B. Growth always brings about development.
C. Development is not a necessary result of growth.
D. Development is a reliable measure of growth.
Before the 1970s, most development policies were based on theory that economic growth would benefit ________.
A. most people in society B. some people in society
C. few people in society D. everyone in society
according to the study by the World Bank in 1974, economic growth in some backward countries brought ________.
A. benefit to a third of their population
B. benefit to two thirds of their population
C little benefit to their people
D. no benefit at all to their people
If the passage continues, what would the author most likely discuss in the next paragraph?
A. How to turn growth into development.
B. How to remove poverty from society.
C. How to decrease the third world debt.
D. How to cope with economic crises.
