The "life-saving effect" occurred as the volume of phones grew into the early 1990s, and increasing numbers of cells were used to call 911 following accidents, leading to a drop in fatalities, explains Loeb. But this life-saving effect was canceled out6 once the numbers of phones reached a "critical mass" of about 100 million and the "life-taking effect" - increased accidents and fatalities outweighed the benefits of quick access to 911 services, according to Loeb.
Loeb and his co-authors used econometric models to analyze data from a number of government and private studies. He and his co-authors recommend that governments consider more aggressive policies to reduce cell phone use by both drivers and pedestrians, to reduce the number of fatalities.
36.The two new studies, lead-authored by Professor Peter D. Loeb
A.show that talking on the phone while driving or walking in the street increases deaths of drivers and pedestrians.
B.show that talking on the phone while driving increases pedestrian deaths.
C.recommend that strict measures be taken to restrain cell phone use.
D.both A and C.
37.According to the second paragraph, when did cell phones actually help to reduce pedestrian and traffic fatalities?
A.Right after cell phones were invented.
B.Before the number of cell phone users reached a critical mass
C.When cell phone users totaled to a certain number.
D.When the number of cell phones decreased to a certain number. www.lexue88.com
38.What is said about cell phone use in the mid-1980s in paragraph 5?
A.It had a life-taking effect because there weren't enough cell phones in use then.
B.The increased use of cell phones then caused a "life-taking effect."
C.Traffic fatalities increased then because the number of cell phones in use decreased.
D.Traffic fatalities decreased then because the number of cell phones in use increased.
39.What is said about cell phone use in paragraph 4?
A.The number of cell phones in use exploded in the late 1980s and part of the 1990s.
B.The number of traffic deaths was reduced in the late 1980s and part of the 1990s due to cell phone use.
C.Cell phone users are likely to be involved in traffic accidents.
D.The use of cell phones has a life-saving effect for pedestrians and drivers.
40.Which of the following statements DOES NOT answer the question "What caused the "life-saving effect" to occur in the early 1990s?"
A.There were more cell phone users during that period.
B.The number of cell phone users reached about 100 million.
C.More cell phones were used to call 911 when accidents occurred.
D.Cell phones enabled people to have quick access to 911 services.

Oil Refining
An important new industry, oil refining, grew after the civil war. Crude oil, or petroleum --- a dark, thick ooze from the earth --- had been known for hundreds of years. But little use had ever been made of it. In the 1850’s Samuel M. Kier a manufacturer in western Pennsylvania, began collecting the oil from local seepages (油苗) and refining it into kerosene. Refining, like smelting is a process of removing impurities from a raw material.
Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was becoming harder to get. Soon there was a large demand for kerosene. People began to search for new supplies of petroleum.
The first oil well was drilled by E.L.Drake, a retaired railroad conductor. In 1859 he began drilling in Titusvill, Pennsylvania. The whole venture seemed so impractical and foolish that onlookers called it “ Drake’s Folly”. But when he had drilled down about 70 feet (21 meters ), Drake struck oil and his well began to yield 20 barrels of crude oil a day.
News of Drake’s success brought oil prospectors to the scene. By the early 1860’s these wildcatters were drilling for “black gold “ all over western Pennsylvania. The boom rivaled the California gold rush of 1848 in its excitement and Wild West atmosphere. And it brought far more wealth to the prospectors than any gold rush.
Crude oil could be refined into many products. For some years kerosene continued to be the principal one. It was sold in grocery stores and door-to-door. In the 1880’s and 1890’s refiners learned how to make other petroleum products such as waxes and lubricating oils. Petroleum was not then used to make gasoline or heating oil.
41.What is the best title for the passage?
A.Oil Refining : a historical perspective
B.The California Gold Rush: Get Rich Quickly
C.Private Property: Trespassers Will Be Prosecuted
D.Kerosene Lamps: A Light In the Tunnel
42.It can be inferred from the passage that kerosene was preferable to whale oil because whale oil was too_______.
A.expensive
B.thick
C.hot
D.polluted
43.According to the passage, many people initially thought that E. L. Drake had made a mistake by ________.
A.going on a whaling expedition
B.moving to Pennsylvania
C.retiring from his oil
D.retiring from his job
44.The author mentions all of the followings as possible products of crude oil EXCEPT _____.
A.wax
B.gasoline
C.kerosene
D.plastic
45.Why does the author mention the California gold rush?
A.To explain the need for an increased supply of gold
B.To indicate the extent of United States mineral wealth
www.lexue88.com C.To describe the mood when oil was first discovered
D.To argue that gold was more valuable than oil

Looking into the Future
Bertrand Russell, a famous philosopher, said in 1944, “The one thing the study of the past teaches us is that the future is never how people imagine it will be.”
In 1946, physicists predicted that within twenty years, most of the world’s energy would be supplied by nuclear power. __________ (46) In 1951, a famous surgeon said that he and his colleagues were confident that “by the end of the 1950s, a cure for most if not all cancers will have been found.” In 1954, an American economist predicted Americans would go on getting richer and richer. ___________ (47).
In the year 1969, an automation engineer working for Max Factor Cosmetics in Britain said that “within twenty or twenty-five years factories that today employ hundreds of workers will need only five or ten computer technicians to run them.” _____________ (48).
In the early 1970s, there were many predictions that before the end of the century most homes in the United States, Europe and Japan would have computers in them. ___________ (49)
Long before 1980, it was predicted that instead of letting nature and luck choose their children’s characteristics, people would have to decide which characteristics they wanted their children to inherit from them and previous generations in their families. ____________ (50)We may be able to have “undesirable” characteristics changed or destroyed through genetic therapy. Perhaps we may even begin to wish that Bertrand Russell was right when he said that history teaches us that the future is never like that future we imagine.
A. “By the end of the century,” he said, “there will be no poverty anywhere in the country.”
B. If this prediction comes true, we will be faced with a much greater responsibility than ever before.
