Question

Searching the Internet may help middle-aged and older adults keep their memories sharp,US researchers said.
Researchers at the University of California, Los Angeles ,studied people doing web searches by recording their brain activity.
“What we saw was people who had Internet experience used more of their brain during the search,”Dr.Gary Small, a UCLA expert on aging, said,“This suggests that just searching on the Internet may train the brain and that it may keep it active and healthy.”
“This is the first time anyone has simulated(模擬)an Internet search task while scanning the brain,”Small said. His team studied 24 normal volunteers between the ages of 55 and 76. Half were experienced at searching the Internet and the other half had no web experience. However, the two groups were similar in age, gender and education.
Both groups were asked to do Internet searches and book reading tasks while their brain activity was monitored.
“We found that in the book reading task, the visual cortex— the part of the brain that controls reading and language — was activated,”Small said,“In doing the Internet search task, there was much greater activity, but only in the Internet-savvy（了解）group.”
He said it appears that people who are familiar with the Internet can engage in much deeper level of brain activity. Activities that keep the brain engaged can preserve brain health and thinking ability. Small thinks learning to do Internet searches may be one of those activities.

Answer 1

小題1:D
小題2:A
小題3:B
小題4:C

試題分析：這篇文章講述的是通過研究表明，進(jìn)行網(wǎng)絡(luò)搜索比閱讀書籍更有助于中老年人保持良好的記憶。
小題1:細(xì)節(jié)題。由第五段Both groups were asked to do Internet searches and book reading tasks while their brain activity was monitored.兩組志愿者被要求去做網(wǎng)絡(luò)搜索和閱讀書籍的時(shí)候，他們的大腦活動(dòng)被監(jiān)控了。故選D
小題2:由第四段His teamstudied 24 normal volunteers between the ages of 55 and 76. Half were experienced at searching the Internet and the other half had no web experience. However, the two groups were similar in age, gender and education.研究了24名志愿者，他們的年齡在55到76歲之間，其中一半有過網(wǎng)絡(luò)搜索的經(jīng)歷，另一半沒有。然而，這兩組在年齡，性別和學(xué)歷上是相似的。故選A
小題3:細(xì)節(jié)題，由最后一段He said it appears that people who are familiar with the Internet can engage in much deeper level of brain activity.看起來是熟悉網(wǎng)絡(luò)的人能夠進(jìn)行更深層次的大腦活動(dòng)。故選B
小題4:細(xì)節(jié)判斷題。由倒數(shù)第二段We found that in the book reading task, the visual cortex— the part of the brain that controls reading and language — was activated。我們發(fā)現(xiàn)當(dāng)閱讀書籍的時(shí)候，視覺皮質(zhì)——控制閱讀和語言的那部分大腦——被激活了。故A錯(cuò)誤。
由Dr.Gary Small, a UCLA expert on aging，可知B錯(cuò)誤。
Activities that keep the brain engaged can preserve brain health and thinking ability.網(wǎng)絡(luò)搜索活動(dòng)能夠保持大腦的健康和思考能力。故C正確。
由people who are familiar with the Internet can engage in much deeper level of brain activity.熟悉網(wǎng)絡(luò)的人比閱讀書籍的人能夠進(jìn)行更深層次的大腦活動(dòng)，故D錯(cuò)誤，故本題選C
點(diǎn)評：本文對兩種現(xiàn)象進(jìn)行了相關(guān)的實(shí)驗(yàn)，對于此類題，可以通過對于兩項(xiàng)實(shí)驗(yàn)的結(jié)果來迅速的理解全文。答題過程中可以對文章的大意進(jìn)行了解，在結(jié)合題目，相信每個(gè)題目都在文章中能找到相應(yīng)的地方，把握好作者的意思準(zhǔn)確作答。
