【文章內(nèi)容簡介】 C. Who Should Go to the Dentist Frequently? D. How Can We Go to the Dentist Less? D It’s a saying favored by grandparents, a eback beloved enough to make an appearance on countless Tshirts, “I’ve fotten more than you know.” Now, a team of researchers has offered some support for the idea that the sloweddown recall we associate with getting older may sometimes be a side effect of a mind that’s filled with decades of information not a symptom of certain cognitive (認(rèn)知的 ) decline. The findings are based on a series of puter simulations (模擬 ) of learning and memory, not tests of actual people. The basic idea is that “the larger the library you have in your head, the longer it usually takes to find a particular word,” Benedict Carey says. The researchers propose that over time, you store more and more data in your mind, making recalling a needed item (條目 ) whether that’s a word, a name, or information to make a decision harder and slower as you get older. But Michael Ramscar, a famous scientist, says puter simulations can only be trusted after years of testing on thousands of humans. “We not only found that a researcher’s choice of test can determine whether cognitive functioning appears to decline or improve with age, we also found that the results of the same cognitive test can suggest agerelated declines or improvements.” Patrick Rabbitt says even the study’s idea “that old brains contain more information than young brains” is unfounded. “It is also arguable becaus e it requires an extra assumption that all the information that our brains ever process is permanently recorded and bees progressively (漸進(jìn)地 ) less accessible only because mental congestion (擁堵 ) increases,” he says, “those who have larger vocabularies and more knowledge of the world must be slower” “In fact,” Rabbitt writes, “the opposite is the case.” 12. The first paragraph serves as a(n) ______. A. explanation B. introduction C. ment D. background 13. What does Benedict agree with? A. We can store as much information in our mind as a big library does. B. Remembering too much information slows down our decisionmaking process. C. The information we store in our mind will reduce slowly as we grow old. D. All the information in our mind is a mixture of names and words. 14. Ramscar considers the results of many cognitive tests ______. A. pletely wrong B. convincing C. controversial D. impressive 15. We can know from the last paragraph that Rabbitt think ______. A. old brains have more data than young brains B. people with large vocabularies are slower C. the information in our brain is permanently stored D. those who have more knowledge are quicker 第二節(jié) （共 5小題；每小題 2分，滿分 10 分） 根據(jù)對話情景和內(nèi)容，從對話后的選項中選出能入空白處的最佳選項。選項中有兩項為多余選項。 If something that you’re doing doesn’t challenge you, then it doesn’t change you. We all need some normal stress in our lives, after all. 16 So challenge the following limits: 1. Figure out what you’re scared of and do it continuously . If you’re a salesman, and you’re scared of talking to people personally or over the phone, now, instead of being scared and thinking you’ll fail, spend at least five minutes a day to pick up the phone and make a call. 17 But don’t stop on the first try! Eventually, you can look at fear in the eyes and say, “Go on, I’m not scared!” 2. 18 Make sure this hobby is not linked to your career。 you have to relax and relieve your stress while performing this. Some examples might be cooking, sewing, painting and so on. Apart from helping you challenge yourself, taking a class for your hobby may also give you extra ine. 3. Set aside at least nine minutes a day for physical exercise. 19 A simple 9minute run around your neighborhood can do wonders for yourself. Exercise can not only help you maintain your regular weight, but also make you feel better about yourself. 4. Travel and allow yourself to be interested in new people. Don’t just limit yourself to y our fellow travelers try to connect with the service staff. You never know what kind of people they’re going to be . Get out of your house or go online right no
