A．affect；effect       B．affected；effect

C．affected；effects      D．affect；effects

解析　affect为及物动词“影响”；effect为名词。另外have an effect on为固定搭配，意为“对……有影响”，故选B项。

A．suggest　　　　　　　　 B．suggests

C．suggested   D．suggesting

解析 考查时态和主谓一致。句意：有许多人依旧在公共场合吸烟，这一事实表明我们也许需要搞一次全国性的活动来提高人们对于吸烟危害性的认识。the fact后跟同位语从句，设空处为主句的谓语动词，故排除D项；由题干中的smoke和may等可知语境指现在的情况，故排除C项。本句主语为the fact，且本句陈述的是一个事实，故谓语动词应采用第三人称单数形式，故选B项。

答案 B

Ⅱ.阅读理解

What happens inside the skull of a soccer player who repeatedly heads a soccer ball？That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players，and some anxiety among those of us with soccer­playing children.

For the study，researchers at the Albert Einstein College of Medicine in New York selected 34 adults，men and women.All of the volunteers had played soccer since childhood and now competed year­round in adult soccer leagues.Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year，as well as whether they had experienced any known concussions (脑震荡) in the past.

Then the players completed computerized tests of their memory and other learning skills and had their brains scanned，using a complicated new MRI technique which can find structural changes in the brain that can’t be seen during most scans.

According to the data they presented at a Radiological Society of North America meeting last month，the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory，attention and the processing of visual information，compared with players who had headed the ball fewer times.

This pattern of white matter loss is “similar to those seen in traumatic (外伤的) brain injury”，like that after a serious concussion，the researchers reported，even though only one of these players was reported to have ever experienced a concussion.

The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them，forgetting or fumbling the words far more often than players who had headed the ball less.

语篇解读：　研究表明，经常用头顶球会对大脑的内部构造造成严重影响，进而影响人的记忆力、注意力以及对视觉信息的处理能力。

1．The passage is most probably a________.

A．news report 　　 B．research report

C．story for soccer players　　 D．text for doctors

解析　推理判断题。根据第二段开头部分中的内容可推知，本文是一篇研究报告。

答案　B

2．From the passage we can conclude that frequent heading may have________.

A．significant effect on one’s brain

B．little effect on one’s brain

C．nothing to do with the brain injury

D．one’s memory improved

解析　推理判断题。根据第四段中的“the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains”可推知，频繁地用头顶球对大脑有显著的影响。

答案　A

3．What is likely to be the cause of memory loss?

A．Playing soccer frequently.

B．Tests of their memory.

C．White matter loss.

D．Information processing.

解析　细节理解题。结合第四段中的“loss of white matter in parts of their brains involved with memory”以及下一段的开头部分可知，记忆力的丧失可能与大脑中的白色物质缺失有关。

答案　C

4．The underlined word “fumbling” is closest in meaning to________.

A．remembering 　　 B．misunderstanding

C．recalling 　　 D．missing

解析　词义猜测题。结合画线词前面的“worse at recalling lists of words”和“forgetting”可推知，fumbling与missing的意思最相近。

答案　D
