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(違反直覺的),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)smokinghowever,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(認知的)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.

1.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.

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.

3.From the passage we can learn that .

A.cigarette smoking is not related to reasoning

B.nicotine exposure can improve mental functioning temporarily

A.many alcoholics suffer a great deal from smoking

B.giving up smoking is significantly challenging for the alcoholics

C.a(chǎn)lcoholics who do not smoke much have higher IQ scores

試題分析:根據(jù)調(diào)查發(fā)現(xiàn)尼古丁對人體神經(jīng)的長期影響在某種程度上是嗜酒成癮者智力下降的主要原因,因為他們中很多人同時也是老煙民。盡管抽煙并不是導致嗜酒成癮者神經(jīng)系統(tǒng)識別功能降低的全部原因,但確實有一定的影響。提醒人們抽煙對智商和思維能力有消極的影響。

1.這是主旨大意題。根據(jù)In her study,“Cigarette smoking has a bad effect on IQ and thinking,抽煙對智商和思維能力有消極的影響,故選A。

2.這是細節(jié)理解題。因為很多人都覺得在抽完煙后反應會更敏捷,注意力更集中。研究結果顯示,抽煙后確實會有短暫的意識功能增強,但這只是尼古丁釋放的短暫效果之一。然而,長期抽煙會產(chǎn)生相反的效果。故選C。

3.這是細節(jié)理解題。Indeed,research shows that improved mental functioning is one of the immediate effects of nicotine exposure研究結果顯示,抽煙后確實會有短暫的意識功能增強故選B。

4.這是推理判斷題。根據(jù)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.研究報告認為,盡管抽煙并不是導致嗜酒成癮者神經(jīng)系統(tǒng)識別功能降低的全部原因,但確實有一定的影響。故選D。

5.這是寫作意圖題。抽煙對智商和思維能力有消極的影響。故選A。

考點:這是一篇社會類的文章。

點評:推理判斷就是根據(jù)作者的意圖和傾向來完成相關的問題。 根據(jù)你對文章的理解,來判斷各個選項的正誤。最重要的就是讀懂句子的意思,找出文章的中心,這種閱讀是深層閱讀,但是你最重要的就是找出文章的中心意思,抓住主要句子和相關句子的意思就可以解決了,要注意題目中的一些關鍵詞和文章中的句子的對比,尤其是一些轉(zhuǎn)折詞、連詞等等。

Depression(抑郁癥)is a serious problem today.Depression causes workers to be unproductive,causing companies and countries to lose billions of dollars.One expert says that depression is like cancer because it is “widespread,costly and deadly”.Depression hits one person in five around the world.

Although people have believed depression to be a problem among the rich and educated,studies show that depression is a problem among everyone。Over any six-month period,between five to seven percent of the world's population will be suffering from a serious depression.

suicide(自殺)rates among people suffering from the disease in its extreme,or clinical form were 80 percent higher than in the population at large,and sufferers were four times more likely to have heart attacks. People who suffer from depression often have problems sleeping,getting up on time,and doing work productively.

Depression,which researchers agree has its origin in the genes(基因),brings loss of confidence and ability to concentrate-making it impossible for employees and managers to work efficiently.

Depression is made more serious in China by Chinese's inability to face it.Many people believe that depressed people are either weak or lazy.  Besides,there is no good treatment,with few specialists available.

“Most patients in China just don't get help,”a Chinese doctor says.“In my hospital.I have to see 30 or 40 patients in a morning,just have time to say “Hello how do you feel?”

In Western countries,people are not afraid to admit that they have depression,but most do not tell it to their boss,because they fear that their boss would fire them.

“In my experience,aging bosses are the most willing to admit they have it. Because they feel the most secure about themselves,”an American doctor says.

Hopefully,in the near future,people around the world will be able to admit that they have depression so that they can get the right treatment.

Children are being indirectly affectly by the impact of the recession (經(jīng)濟衰退) on their parents, the Children’s society warns.

The chief executive of the Children’s Society, Bob Reitemeier, said that children were “on the front of recession”. He said the recession made it even more important to try to end child poverty.

The answers suggest children from poorer backgrounds are more likely to be affected, but over a third of children across all backgrounds said they were aware that the recession was worrying their parents.

Fifteen-year-old Patricia said her family felt the impact of the recession on their everyday budget(預算). “We have to save up our money and do not spend it so much on unnecessary things,”she said.

Those questioned appeared to have great awareness of the economic crisis, which, unsurprisingly, was higher among the older children. But around 15% said they hadn’t been affected by it.

Recent figures showed that in 2007 there were 850,000 young people with no particular occupation. An official from the government said it was so “disappointing” that some young people were concerned about the economy.

Parents are clearly best placed to talk to their children about their worries, but schools also play an important role in teaching young people the skills they need to become healthy, happy and confident individuals.

(    )68.Which of the following is true?

A. It is more important to try to end child poverty in the recession.

B.Children from poorer areas are less likely to be affected.

C.All the children questioned are worried about the economy.

D.That some young people are worrying about the economy is “good news”.

(    )69.What does the underlined word “it” refer to in Paragraph 5?

A. The poorer background.   B.The impact of the recession. 

C. Everyday budget.        D.The government.

(    )70.What’s the main idea of the passage?

A. Many children are concerned about the recession.

B.Children are being directly affected by the recession.

C.The recession affected children indirectly.

D. Schools play an important role in teaching young people how to become healthy, happy and confident individuals.
