六、阅读理解
Are you afraid of going to the dentist If so, you're not alone.
The fear could just be in our heads, however. According to a recent survey by Martin Tickle, a professor at The University of Manchester in the UK, the pain isn't felt most of the time in dental surgeries (牙科手术). In fact, among the 451 interviewed patients, 75% reported no pain at all during their visits, including situations when they had their teeth pulled out.
Could it be the sound of the drill(钻机)then
"I found that the sound of drilling can evoke worry in dental patients' mind. Actually they don't have any pain," Hiroyuki Karibe, a scientist at The Nippon Dental University in Tokyo, told The Guardian.
To find the reason why a drill might bring on a racing heart, Karibe divided the volunteers into low-fear and high-fear groups based on how much they feared a trip to the dentist. Volunteers were played the sound of a drill while their brain activities were watched by a machine.
What Karibe found in the low-fear group was increased activity in the area of the brain relative to auditory processing(听觉处理), which means, for these people, the sound of dental drills is no different from other sounds.
In the high-fear group, however, the brain area that was activated(激活) was different. It was the area that carries out a number of duties, including learning, feeling and, most importantly, memorizing. This means that these volunteers not only heard the sound, but they remembered it — they made connections between the sound of a drill and the worry it produced in the past, causing their worry to return.
"Understanding how brains reply to the sounds of dentists' drills could help scientists find ways to make patients more relaxed," according to Karibe, "because patients who worry about going to the dentist might keep putting off their visits. But the best way is to keep your teeth healthy."
1.How does the writer explain that the pain isn't felt most of the time in dental surgeries
A. By showing facts with numbers.
B. By asking questions one by one.
C. By giving examples group by group.
D. By comparing results of patients.
2.According to the fourth paragraph, what does the underlined word "evoke" mean in Chinese
A. 减轻 B. 引起
C. 显示 D. 阻止
3.How did the sound of drilling produce different results to the volunteers in the study
A. It produced worry in the volunteers' mind in the low-fear group.
B. For the low-fear group, it activated the brain area dealing with learning, feeling and memorizing.
C. For the high-fear group, it caused activity in the brain area relative to auditory processing.
D. It made people in the high-fear group remember their past uncomfortable memories.
4.What is the last paragraph mainly about
A. How the study might be useful.
B. Some new ways to treat teeth.
C. The proper way to treat dental patients.
D. The importance of keeping our teeth healthy.
5.What's the purpose of the passage
A. To show us different areas in brains.
B. To introduce a recent survey by a scientist.
C. To help us have less fear of a trip to the dentist.
D. To make it clear that the sound of drilling is not terrible.
参考答案
一、词汇运用
1.Germans　German"德国人"为可数名词,且由空前的Three可知,此处应用其复数形式Germans。
2.refused　根据"has already"可知,本句为现在完成时,空处应填动词的过去分词形式。
3.toothache　句意:我总是牙痛。所以我必须记得每天至少刷两次牙。
4.wolves　句意:小心!森林里有许多狼。wolf是可数名词,空前有a lot of修饰,故此处用wolf的复数形式wolves。
5.fortunately　句意:其中一个孩子掉进了河里,但幸运的是他最后得救了。
6.headsets　句意:学生们在自己的电脑上完成这些活动,并戴着耳机与老师交谈。
二、单项选择
1.D　look after=take care of"照顾,照料"。
2.B　 ——我这些天牙不舒服。我不想吃任何东西。——你应该去看牙医。dentist"牙医"符合语境。
3.C　句意:拒绝香蕉很难。它们很好吃,而且在吃它们之前你不用洗(它们)。根据语境可知,before"在……之前"符合题意。
4.C　句意:我叔叔怕发胖,所以很少吃甜食。be afraid of"害怕"符合语境。
5.D　根据"我们错过了闭幕式"可知,此处是说"恐怕除了看回放我们别无选择",应用"have no choice but to do sth."结构。
