A study led by Professor Mark Weiser of Tel Aviv University and the Sheba Medical Center at Tel Hashomer Hospital has determined that young men who smoke are likely to have lower IQs than their non-smoking peers (同龄人). Tracking 18-to 21-year-old men enlisted in the Israeli army in the largest ever study of its kind, he has been able to demonstrate an important connection between the number of cigarettes young males smoke and their IQ.
The average IQ for a non-smoker was about 101, while the smokers’ average was more than seven IQ points lower, at about 94, the study determined. The IQs of young men who smoked more than a pack a day were lower still, at about 90. An IQ score in a healthy population of such young men, with no mental disorders(心理疾病), falls within the range of 84 to 116.
An addiction that doesn’t discriminate(歧视)
“In the health profession, we’ve generally thought that smokers are most likely the kind of people who have grown up in difficult neighborhoods, or who’ve been given less education at good schools,” says Weiser, whose study was reported in a recent version of the journal, Addiction, “But because our study included subjects with various socio-economic backgrounds, we’ve been able to rule out socio-economics as a major factor. The government might want to rethink how it arranges its educational resources on smoking.
Making the results more significant, the study also measured effects in twin brothers. In the case where one twin smoked, the non-smoking twin registered a higher IQ on average.
Although a lower IQ may suggest a greater risk for smoking addiction, the representing data on IQ and smoking found that most of the smokers investigated in the study had IQs within the average range, nevertheless.
In the study, researchers took data from more than 20,000 men before, during and after their time in the military. All men in the study were considered in good health, since pre-screening(筛选的)measures for suitability in the army had already been taken. The researchers found that around 28 percent of their samples smoked one or more cigarettes a day, 3 percent considered themselves ex-smokers, and 68 percent said they never smoked.
“People on the lower end of the average IQ tend to display poorer overall decision-making skills when it comes to their health,” says Weiser. He adds that his finding can help address serious concern among heath counsellors at grade and high schools.

A new report says the number of foreign students at colleges and universities in the United States increased by three percent last year. This has been the first obvious increase since 2001.
American schools last fall had 583,000 foreign students. The record is 586,000. That was set in 2002 after many years of gains. But after that the numbers fell. The terrorist attacks on September 11th, 2001 led to more visa (签证) requirements. Now stronger efforts are being made to get more foreign students to study in the United States.
China remained in second place in front of South Korea but behind India, whichsent almost 84,000 students last fall. The number of Japanese fell sharply by nine percent, although it remained in fourth place.
There were three percent drops from Indonesia and Kenya, the only African country in the top twenty last year. But there were obvious increases from Saudi Arabia, Nepal and Vietnam. The number of Saudi students more than doubled, rising to nearly eight thousand.
For a sixth year, the University of Southern California in Los Angeles had the most foreign students. Columbia University in New York was second. Other schools in the top five were New York University, the University of Illinois and Purdue University.
Unlike American students in other countries, who often choose history and language study, the leading area of study in the USA was business and management. Second was engineering.
The new report also says more than 220,000 Americans studied in other countries. That was during the 2005-2006 school year. It was a record number, and an increase of eight and a half percent from the year before. But only five percent of them stayed for a full year. 【小题1】After 2002, the number of foreign students in the USA fell mainly because ____.
| A．Americans were worried that foreign students might attack them |
| B．few American universities welcomed students from abroad |
| C．their own countries could offer them a better education |
| D．it was harder for foreign students to get permission to study in the USA |

【小题4】We can learn from the passage that ____ .| A．Kenya is the only African country that has students in the USA |
| B．now foreign students are encouraged to study in the USA |
| C．the number of students studying in America always increases |
| D．the number of foreign students in the USA will keep increasing in the future |

A newly-wed couple on a four-month honeymoon were hit by six natural disasters, including the Australian floods, Christchurch earthquake and Japanese tsunami.
Stefan and Erika Svanstrom left Stockholm, Sweden, on December 6 and were immediately stranded in Munich, Germany, due to one of Europe's worst snowstorms. Travelling with their baby daughter, they flew on to Cairns in Australia which was then struck by one of the most tremendous tonadoes in the nation's history. From there, the couple, in their 20s, were forced to shelter for 24 hours on the cement floor of a shopping centre with 2,500 others. "Trees were being knocked over and big branches were scattered across the streets," Mr Svanstrom told Sweden's Express newspaper. "We escaped by the skin of our teeth," said Svanstrom.
They then headed south to Brisbane but the city was experiencing massive flooding, so they crossed the country to Perth where they narrowly escaped raging bush fires. The couple then flew to Christchurch, New Zealand, arriving just after a massive magnitude 6.3 earthquake destroyed the city on February 22. Mrs. Svanstrom said, "When we got there the whole town was a war zone." "We could not visit the city since it was completely blocked off, so instead we travelled around before going to Japan." But days after the Svanstroms arrived, Tokyo was rocked by Japan's largest earthquake since records began. "The trembling was horrible and we saw roof tiles fly off the buildings," Mr. Svantrom said. "It was like the buildings were swaying back and forth."
The family returned to Stockholm on March 29,2011 after a much calmer visit to their last destination China. But Mr. Svanstrom, who also survived the destructive Boxing Day tsunami that hit southeast Asia in 2004, said the marriage was still going strong. He added, "I know marriages have to endure some trials, but I think we have been through most of them." "We've certainly experienced more than our fair share of catastrophes, but the most important thing is that we're together and happy." Mrs. Svantrom added: “ To say we were unlucky with the weather doesn’t really cover it! It’s so absurd that now we can only laugh.”

A deadly strain of avian flu may have passed between people for the first time, experts believe.The avian influenza A (H7N9) virus is thought to have been transmitted between father and daughter in eastern China, according to research published online by the British Medical Journal (BMJ).
The findings provide the strongest evidence yet of H7N9 transmission between humans since its discover in February, but its ability to transmit itself was deemed "limited and non-sustainable" by the Chinese researchers behind the study.At the end of June 133 cases had been reported, including 43 deaths. Most infections have been among people visiting markets, selling live birds or among those who had contact with live poultry（家禽） in the seven to 10 days before becoming ill.
The latest study examined the case of a 60-year-old father who regularly visited a live poultry market and became ill five to six days after his last visit in March. He was admitted to hospital with fever, cough and shortness of breath. Despite intensive care treatment he died of multiple organ failure on 4 May. His 32-year-old daughter, who was previously healthy, looked after him at his bedside before he was admitted to intensive care. She had no known exposure to live poultry before falling ill with a very high temperature, cough and fever. The daughter developed symptoms six days after her last contact with her father and was admitted to hospital where she died of multiple organ failure on 24 April.
Follow-up investigations(调查) uncovered almost genetically identical virus strains from each patient, suggesting transmission from father to daughter. Another 43 people were also tested who had had close contact with the father, daughter or both.
Dr Peter Horby, senior clinical research fellow at the Oxford University Clinical Research Unit in Hanoi, Vietnam, said of the study: "The most likely source of infection for the daughter was her father, during the period that she cared for him while he was ill. "He said “limited person to person transmission had been reported for other strains like H5N1 , H7N7, and the pig origin flu virus H3N2. Those strains had been around for more than a decade but have not progressed any further down the path towards a world-wide virus.” “Limited human-to-human transmission of H7N9 virus is therefore not surprising, but strengthening to monitor it was still needed,” Dr Horby added.
