The poorer mental function seen among alcoholics,many of whom also regularly smoke cigarettes,may be partly due to the long term effects of nicotine(尼古丁),new research suggests.
“People who are also smokers are at a much higher risk,” Dr.Jennifer  M.Glass of the University of Michigan's Addiction Research Center said. In her study,“Cigarette smoking has a bad effect on IQ and thinking,” she said.
This finding may seem counterintuitive(违反直觉的),since many smokers show that they feel quicker and focused after smoking. Indeed,research shows that improved mental functioning is one of the immediate effects of nicotine exposure. Chronic(慢性的)smoking,however,is known to have the opposite effect. Studies show that up to 87 percent of alcoholics smoke cigarettes.
Yet,few studies have looked into cigarette smoking as a factor that might explain the cognitive(认知的)lack reported among alcoholics. To search for that association,Glass and her colleagues examined brain function among 172 men from the same area,including 103 men who abused alcohol. The team found that men with higher scores on the lifetime alcohol problems scale(LAPS)and those who reported a higher number of pack years of smoking both had lower IQ scores.
Upon further research,the researchers found that smoking also appeared to be independently associated  with weaker word and space reasoning.
Thus,though smoking did not account for all of the decreased mental functioning observed among the alcohol abusers,it did seem to account for some of the effects,the report indicates.
What is the passage mainly about?

A.Cigarette smoking contributes to decreased IQ and thinking.
B.Alcohol abuse is to blame for the poorer mental function.
C.Most of the alcoholics are also heavy smokers.
D.Non-smokers mostly have higher IQ scores.

The underline sentence “Chronic smoking, however, is known to have opposite effect” in paragraph 3  suggests:

A.Chronic smoking can improve mental functioning.
B.Chronic smoking has an immediate influence on mental functioning.
C.Chronic smoking has side effect on mental functioning improvement.
D.Chronic smokers feel quicker and focused after smoking.

From the passage we can learn that .

A.cigarette smoking is not related to reasoning
B.nicotine exposure can improve mental functioning temporarily
C.the long term effects of nicotine cause alcoholics
D.men with lower scores on the LAPS have lower IQ scores

It can be inferred from the passage that .

A.many alcoholics suffer a great deal from smoking
B.giving up smoking is significantly challenging for the alcoholics
C.alcoholics who do not smoke much have higher IQ scores
D.other factors can cause the poorer mental functioning besides smoking

The purpose of this passage is .

A.to warn us of the bad effects of smoking on IQ and thinking
B.to tell us why people are addicted to smoking
C.to give us some advice on how to improve IQ and reasoning
D.to compare the bad effects of alcohol and cigarette

PART THREE: READING COMPREHENSION (30分)
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage.
A
At dawn on Friday, May 19, 1780, farmers in New England stopped to wonder at the pink color of the sun. By noon the sky had darkened to midnight blackness, causing Americans, still in the painful struggle of a prolonged war of independence, to light candles and tremble at thoughts of the Last Judgment. As the birds quieted and no storm accompanied the darkness, men and women crowded into churches, where one minister commented that “The people were very attentive.” John Greenleaf Whittier later wrote that “Men prayed, and women wept; all ears grew sharp . . .”
A recent study of researchers, led by Richard Guyette from the University of Missouri’s Tree Ring Laboratory, has shown that vast forest fires in the Algonquin Highlands of southern Ontario and elsewhere in Canada brought this event upon New England. The scientists have discovered “fire scars” on the rings for that year, left when the heat of a wildfire has killed a part of a tree’s cambium (形成层). Evidence collected also points to a drought that year. An easterly wind and low barometric pressure (低气压) helped force smoke into the upper atmosphere. “The record fits pretty close,” says Guyette. “We had the right fuel, the drought. The conditions were all there.”
Lacking the ability to communicate quickly over long distances, Americans in 1780 remained in the dark about the event, which had disappeared by the next day. Over the next several months, the papers carried heated debates about what brought the darkness. Some were the voices of angry prediction, such as one Massachusetts farmer who wrote, “Oh! Backsliding New-England, attend now to the things which belong to your peace before they are forever hid from your eyes.” Others gave different answers. One stated that a “flaming star” had passed between the earth and the sun. Ash, argued another commentator. The debate, carried on throughout New England, where there were no scientific journals or academies yet, reflected an unfolding culture of scientific enquiry already sweeping the Western world, a revolution nearly as influential as the war for independence from the English.
New Englanders would not soon forget that dark day; it lived on in folklore, poems, and sermons for generations.

A. the pink color of the sun B. the darkened sky at daytime
C. the Last Judgment on Friday D. the American War of Independence

B. They swept throughout the Western world.
C. They were organized by scientific institutions.
D. They improved Americans’ ability to communicate.
60. What can be the best title for the text?
A. New England’s dark day. B. Voices of angry prediction.

A wallet misplaced during a romantic embrace has been returned to its forgetful owner after 55 years.
Two classic car collectors from the US state of Idaho found the wallet after it fell out of the back of a vintage(旧式的)car they were planning to restore.After an Internet search they found and contacted the owner,Glenn Goodlove.Mr.Goodlove said he probably lost the wallet in the back seat of his 1946 Hudson car when he was home on leave from the US Navy.
Jon Beck,61,and Chuck Merrill,72,bought the now-vintage vehicle in Idaho after placing an ad in a local newspaper to buy a classic car in need of restoration.Driving the car home after buying it,the collectors stopped at a restaurant and saw something from below the back seat.
“Like a couple of kids,we thought we had a goldmine,”Mr.Beck said.Instead,they found some small change--the leather wallet held a$10 bill,Mr.Goodlove’s military ID, his social security card,his driver's license and several jewellery receipts from 1952.But they were all in the name of Glenn Putnam.
After searching online,Mr.Beck discovered that Mr.Putnam had changed his name to Glenn Goodlove and moved to San Diego,California.He called Mr.Goodlove,asking to speak to a man who used to drive a’46 Hudson.
“There was a silence for about 15 seconds,”Mr.Beck told the Twin Falls Times-News.“Then he said,‘Who is that?”Mr.Goodlove,now 75,says he did not even remember losing the wallet,but the find has brought memories of his youth in Everett,Washington,flooding back.“I could see the house and the car and the town and all the good stuff from living there”’he said.“They’ve been flowing ever since he talked to me.”

Zanzibar,Tanzania--Hundreds of dead dolphins were washed up on Friday along the shore of a popular tourist place on Tanzania’s northern coast.Scientists have ruled out poisoning.
It was not immediately clear what killed the 400 dolphins,whose dead bodies lied along a 4-kilometer coast of Nungwi,said Narriman Jidawi,a marine biologist at the Institute of Marine Science in Zanzibar.But the bottleneck dolphins,which live in deep offshore waters,had empty stomachs,meaning they could have got lost and had been swimming for some time to reorient themselves.They did not die of hunger and were not poisoned,Jidawi said.
In the US,experts were looking into the possibility that sonar(声呐)from the US submarine could have caused a similar incident in Marothon,Florida,where 68 deep-water dolphins stranded(搁浅)themselves in March 2005.
The deaths are a blow to the tourism industry in Zanzibar,where thousands of visitors go to watch and swim with dolphins.Villagers,fishermen and hotel residents found the dead bodies and told officials.Mussa Aboud,Zanzibar’s director of fisheries,went on state radio to warn the public against eating the dolphins’meat,saying the cause of death had not been found.
The Indo-Pacific bottlenose,commonly known as dolphins,are the most common species in Zanzibar’s coastal waters,with bottlenose and humpback dolphins often found in mixed-species groups.
63.According to the passage,the bottleneck dolphins
A.are often attacked by submarine in deep water
B.find it hard to find enough food near the coast
C.often fall ill along the shore of a tourist place
D.1ike living in the deep waters near the coast
64.The underlined word“reorient”means
A.lose their way B.find their way
C.look for food D.fight against enemies
65.What can we infer from the passage?
A.The dolphins died because of the sonar from US submarines.
B.The dead dolphins can not be eaten as they are poisonous.
C.The US experts are researching sonar at present.
D.The ability of locating is extremely important for dolphins.
66.What would be the best title for the passage?
A.400 dolphins died along the coast of Nungwi.
B.Dolphins are facing increased risk of death.
C.It’s necessary for us to protect dolphins.
D.Nungwi is famous for many dolphins there.

Residents along Australia’s east coast awoke in the morning to an orange sky as winds swept millions of tons of red dust from the country’s inland and dumped it on Sydney.
Tanya Ferguson,living in Sydney,saw that the room was completely orange.She thought there was a bush fire.But when she went outside,the entire city was covered in a film of orange dust.
“It was like being in the outback(澳大利亚内陆),but it was right here in the city,”she said On that day,a big dust storm swept through Sydney.It covered the city in orange dust for about eight hours,making landmarks such as the Sydney Opera House and Harbor Bridge invisible.
The storm affected the transportation system.Flights were delayed.Roads were busy as drivers struggled in the difficult conditions.Children and the elderly were told to stay indoors until the dust had cleared.Later strong winds blew it out to the sea and up the coast.
No one was hurt in the storm,though health officials answered hundreds of calls from
people with breathing difficulties.Emergency services responded to hundreds of calls about
tree branches brought down by strong winds.
Dust storms are common in the Australian outback,where the land is arid(贫瘠的).But the storms rarely reach the coastal regions.
Officials said it was the worst dust storm of the past 70 years.Air pollution levels were
15,500 micrograms of pollutants per cubic meter.
“On a clear day the pollutants are around 10—20 micrograms per cubic meter,”said Chris
Eiser of the NSW department of the environment.
Experts said that dry conditions in the outback and strong winds caused the sandstorm.
“Ten very dry years over inland southern Australia and very strong winds have combined to produce the storm,”said Nigel Tapper,an environmental scientist at Monash University, Australia.
56.The article is about
A.the causes of the major dust storm in Australian cities
B.different reactions to a dust storm in Australia
C.the damage caused by the big dust storm in Australia
