Question

【题目】People who smoke could lose around one third of their daily memory, researchers say.

A study by a team at Northumbria University showed that smokers lost more of their memory when compared to non-smokers.

And the research also found that those who kicked the habit saw their ability to recollect information back to almost the same level as non-smokers.

The study involved more than seventy 18-to-25-year-olds and included a research of the university .Those who took part were asked to recall small details, such as a list of songs played at the Students’ Union and tasks completed at various points .

Smokers performed badly, remembering just 59 %of tasks. But those who had given up smoking remembered 74 %and those who had never smoked recalled 81 % of tasks.

Dr. Tom Heffernan, who leads Northumbria University’s Collaboration for Drug and Alcohol Research Group, said the findings would be useful in movements against smoking. He said, “This is the first time that a study has set out to examine whether giving up smoking has an effect on memory.”

“We already know that giving up smoking has huge health benefits (好处)for the body, but this study also shows how stopping smoking can have knock-on benefits for cognitive functions （认知）too. ’’

A. 15% less than those who have never smoked

B. 33% less than those who have given up smoking

B. nobody believes the result of the research by Tom Heffernan’s team

C. nobody will risk their health or even life to go on smoking anymore

D. nobody had done the same research as Tom Heffernan’s team before

【3】According to Tom Heffernan, it is necessary for smokers to ______.

A. train their memory B. give up smoking

C. remember small details D. Be given more tasks

【2】D

【3】B

【4】A

【解析】本文讲述的是抽烟对人的记忆力影响的实验，想通过这个实验来告诉人们，吸烟不仅对身体健康有害，而且影响人的记忆力。

【1】题意：Tom Heffernan团队的研究表明，吸烟者的记忆力_____________。A. 15% less than those who have never smoked比从未吸烟的人低15%；B. 33% less than those who have given up smoking比戒烟者低33%；C. 22% less than those who have never smoked比从未吸烟的人低22%。D. 22% less than those who have given up smoking比戒烟者低22%。根据第四段最后3行Smokers performed badly，remembering just 59 percent of tasks．But those who had given up smoking remembered 74 percent and those who had never smoked recalled 81 percent of tasks．（吸烟者表现糟糕，只记得59%的任务。但是那些戒烟的人记得74%，而从未吸烟的人回忆了81%的任务。）可知吸烟者的记忆力比戒烟者低74%-59%=15，比从未吸烟者低81%-59%=22%；故选C。

【2】题意：从文章中可以得知，____________________。A. nobody shows any interest in research by Tom Heffernan’s team没有人对Tom Heffernan团队的研究感兴趣；B. nobody believes the result of the research by Tom Heffernan’s team没有人相信Tom Heffernan团队的研究结果；C. nobody will risk their health or even life to go on smoking anymore没有人会冒着健康的危险甚至生命危险去抽烟。D. nobody had done the same research as Tom Heffernan’s team before以前没有人和Tom Heffernan的团队做过同样的研究。根据第5段最后一句He said, “This is the first time that a study has set out to examine whether giving up smoking has an effect on memory.”（他说：“这是一项研究首次发现戒烟是否对记忆有影响。”）可知D是正确的。

【3】题意：根据Tom Heffernan的说法，吸烟者_____________是必要的。A. train their memory训练他们的记忆力；B. give up smoking戒烟；C. remember small details记住小细节；D. Be given more tasks被赋予更多的任务。根据最后一段“We already know that giving up smoking has huge health benefits (好处)for the body, but this study also shows how stopping smoking can have knock-on benefits for cognitive functions （认知）too. ’’（“我们已经知道戒烟对身体有巨大的健康益处，但这项研究也表明戒烟对认知功能也有好处。”）可知根据Tom Heffernan的说法，吸烟者戒烟是有必要的。故选B。

【4】题意：下面哪一个可以作为文章的恰当标题？A. Warning :Smokers could be more forgetful. 警告：吸烟者可能更健忘；B. Warning: Smokers wouldn’t get back memory警告：吸烟者不会恢复记忆；C. Warning: Smoking must be harmful to health警告：吸烟有害健康；D. Warning: Smoking might cause mental problems警告：吸烟可能引起精神问题。本文讲述了Tom Heffernan团队做了抽烟对人的记忆力影响的实验，研究表明：吸烟者表现糟糕，只记得59%的任务。但是那些戒烟的人记得74%，而从未吸烟的人回忆了81%的任务。根据本文主要内容可知“吸烟者可能更健忘。”作为本文标题最好，选A。
