1、Smoking Can Increase Depressive Symptoms in Teens
While some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens.
"This observational study is one of the few to examine the perceived emotional benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating ____ or to improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "
As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools located in high, moderate and low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood or physical state; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had trouble going to sleep or staying asleep; felt unhappy, sad, or depressed; felt hopeless about the future; felt vexed, antsy or tense; and worried too much about things.
"Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O'Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."
The association between depression and smoking exists principally among teens that use cigarettes to feel better. "It's important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.
【单选题】

A.effects

B.methods

C.steps

D.directions

正确答案:A

答案解析:句中的or是“即”，也就是说，to have self-medicating加上填入的词之后的意思相当于to improve mood。四个选项中只有选项A的effects（效果）是填入空格的最合适的词。to improve mood是自我治疗的效果。其他三个选项methods、steps、directions与self-medicating连用，意思分别为“自我治疗的方法”、“自我治疗的步骤”、“自我治疗的指导”，与句子的意思不相配。

2、Youth Emancipation in Spain
The Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest.
Around 55 percent of people aged 18 ～ 34 in Spain still sleep in their parents' home, says the latest report from the country's state - run Institute of Youth.
To coax (劝诱) young people from their homes, the Institute started a "Youth Emancipation(解放)" programme this month. The programme offers guidance in finding rooms and jobs.
Economists blame young people's family dependence on the precarious (不稳定的) labour market and increasing housing prices. Housing prices have risen 17 percent a year since 2000.
Cultural reasons also contribute to the problem, say sociologists (社会学家). Family ties in south Europe (Italy, Portugal and Greece) are stronger than those in middle and north Europe, said Spanish sociologist Almudena Moreno Minguez in her report "The Late Emancipation of Spanish Youth: Key for Understanding".
"In general, young people in Spain firmly believe in the family as the main body around which their private life is organized," said Minguez.
In Spain, especially in the countryside, it is not uncommon to find entire groups of aunts, uncles, cousins, nieces and nephews (外甥／侄子) all living on the same street. They regularly get together for Sunday dinner.
Parents tolerance is another factor. Spanish parents accept late - night partying and are wary of setting bedtime rules.
"A child can arrive home at whatever time he wants. If parents complain he'll put up a fight and call the father a fascist," said Jose Antonio Gomez Yanez, a sociologist at Carlos Ill University in Madrid.
Mothers willingness to do children's household chores (家务) worsens the problem. Dionisio Masso, a 60 - year - old in Madrid, has three children in their 20s, The eldest 28, has a girlfriend and a job. But life with mum is good.
"His mum does the wash and cooks for him, in the end, he lives well," Masso said.
It can be inferred from paragraph 5 that family ties are stronger in Portugal than in ______.【单选题】

A.Greece

B.Finland

C.Spain

D.Italy

正确答案:B

答案解析:本题难度不大，是送分题。第五段第二句谈到了欧洲南部国家的家庭联系比欧洲中部和北部的国家更紧密，结合地理知识，芬兰位于北部，所以答案是B，此外，即使不靠地理知识，也可使用排除法做对这道题目，作者列举了三个国家都是在欧洲南部，选项A，C，D都是作者提到的，可以明显被排除掉，答案只能是B。

3、In the process, the light energy converts to heat energy.【单选题】

A.reduces

4、Gun Rights in the US
Immediately after the shooting at Virginia Tech University, Americans gathered to mourn the dead. The president and the state governor both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons.
Strictly speaking, the US is not the only country where gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the few countries that seems unwilling and politically incapable of doing anything serious to stop it.
In countries like Britain and Canada. The government adopted stricter gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby and the electoral system.
The powerful National Rifle Association, the major supporter of gun rights in the US, is too strong for any party to take on. Most Republicans oppose gun controls anyway. Over the years, the Democrats have found that they can either campaign for gun control or win power, not both; they prefer power.
According to the US Bureau of Justice Statistics, firearm incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So, although opinion polls show most Americans want stricter gun laws, many don't want to give up their arms they keep to protect themselves.
Dave Hancock, a Virginia gun lover, is one example. In an interview he said. "If one professor in Virginia incident had been carrying a legal weapon they might have been able to stop all this. " In his opinion, the massacre is an argument for more people to carry, weapons, not fewer.
But at the root of Americans' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government , commented UK's Guardian newspaper.
One Virginia resident, who had a permit to carry; a concealed firearm, told the Guardian thin itwas every American's responsibility to have a gun.
"Each person," he said, "should not rely solely ____ the government for protection. "
【单选题】

5、Smallpox virus
It's now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?
In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. And the last “official” stocks of live virus bred mistrust of the US and Russia, for no obvious gain.
Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So one again there's a good reason to keep the virus—just in case the disease puts in a reappearance.
How do we deal with the mistrust of the US and Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that's open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn't mean the idea is wrong. If the virus ____ useful, then let's make it the servant of all humanity—not just a part of it.
【单选题】

A.will?be

B.would?be

C.is

D.are

正确答案:C

答案解析:本句是个条件句。从句中动词一般用现在时表示“未来”。这就排除了will?be和would?be。virus是单数，因此D也不正确。故C为正确答案。
