第1题：
However,it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when（ ）to it often enough.A.subjected
B.left
C.drawn
D.exposed答案：D解析：本题所在的句子是一个由when引导的条件句，由主句的主语可以推断，该从句省略了主语和谓语即people are。同时，从句中的it指代的是上文的a certain smell，由此可推断本句意思是：如果人能经常闻到这种气味也能突然对它变得敏感。而四个选项中，只有D.expose一词能与to搭配表示“使某人接触到……”，在这里引申为闻到气味。 -

第一篇
Computer Literacy
There is no denying that students should learn something about how computers work,just as we expect them at least to understand that the internal-combustion engine（内燃机）has something to do with burning fuel, expanding gases and pistons（活塞）being driven. For people should have some basic idea of how the things that they use do what they do.Further,students might be helped by a course that considers the computer's impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy（读写能力）。It is a trade skill that should not be taught as a liberal art.
Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers.But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun,and while our society needs some people who are experts at it,the same is true of auto repair and violin-making.
Learning how to use a computer is not that difficult,and it gets easier all the time as programs become more"user-friendly".Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen.What does the phrase"learning to use a computer" mean? It sounds like"learning to drive a car",that is,it sounds as if there is some set of definite skills that,once acquired,enable one to use a computer.
In fact,"learning to use a computer" is much more like"learning to play a game",but learning the rules of one game may not help you play a second game,whose rules may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program.To be the competent citizens of tomorrow,people should_______.
A:try to lay a solid foundation in computer science
B:be aware of how the things that they use do what they do,
C:learn to use a computer by acquiring a certain set of skills
D:understand that programming a computer is more essential than repairing a car答案：C解析：题干意思为：要成为未来的称职公民，人们应该怎么做。根据文章第2段，未来的称职公民要学习一些电脑的基本技能，但不必像专业编程人员那样。因此答案C为正确选项。
题干意思为：第二段提到的“小提琴制造”是为了说明什么。举这个例子是为了说明第2段的第一句话，即学习使用电脑和学习如何编程是两件截然不同的事情。因此答案D“人们可以使用电脑并不意味着必须了解电脑编程”为正确答案。
题干意思为：学习如何使用电脑正在变得越来越容易，原因是什么。文章第3段指出Learning how to use a computer is not that difficult , and it gets easier all the time as programs become more " user-friendly"，即学习使用电脑不难，并正在变得更加容易，原因是电脑程序正变得“让用户容易使用”，因此可知B为正确选项。
题干意思为：根据作者所述，第三段中“学习使用电脑”是什么意思。这一题的答案在文章的最后一句。即没有教一个人如何使用电脑这回事，一个人只能教别人如何使用这个或那个软件。答案C为学习特定的软件，符合题意。
题干意思为：作者写这篇文章的目的是什么。文章在第一段引出了computer literacy的概念，即“电脑素养”。全篇都是在围绕这个词进行解释。 -

第8题：
单选题It seems obvious that you don"t give away your product for free but this is exactly what indie rock group The Crimea did earlier this year. The band"s reasoning goes like this: more people will download the free album than would pay for it. Therefore more people will heat. The Crimea"s music. These people will then pay money for concerts by the band and perhaps buy a T-shirt or other merchandise. If the band play regular concerts to crowds of 200 or 300 people they can make more money than they would from sales of a CD. There will always be some people who want something they can hold in their hands so they will release the CD into the shops too—but making money through sales of their music isn"t the top priority. The story illustrates the creative thinking going on in the music business in response to dramatic changes over the last few years in the way that people buy music. Sales of music digitally—to computer, phones and MP3 players rose to $2 billion in 2006—an increase of almost 100 percent on the previous year—yet overall record company sales are down. People are simply not buying CDs in record shops in anything like the numbers they used to. This trend looks set to continue, so the big question for the music industry is whether they can successfully manage the move to being primarily a digital industry without profits falling to unacceptable levels. There are both positive and negative signs. On the plus side, more and more people are buying music on mobile phones, which allows people to make impulse purchases—they can buy a song as soon as they hear it. Research by the UK mobile operator 3 suggested that 75 percent of 16 to 24-year-olds wanted to buy a track they liked as soon as they heard it. With so much competition for people"s disposable income, a product that you can sell immediately is a big advantage. The bad news for record companies, however, is the amount of music that is downloaded illegally. Piracy—usually in the form of cheaply copied CD—has long been an issue for the music business but the Internet means music can be copied and distributed freely through file-sharing sites on a large scale than ever before. It is this situation that leads bands to start giving away their music for free and promises to make the next few years a very interesting time in the music business.What effect has the Internet had on music piracyAIt has made it easier to fight piracy.
BIt has increased the number of pirate CDs available.
CIt has made it easier to illegally copy music.
DIt has reduced the number of pirate CDs available.
正确答案： B解析： [解析] 推理判断题。题干的大意是：互联网对音乐盗版有什么影响从文中第五段第二句“the Internet means music can be copied and distributed freely through file-sharing on a large scale than ever before”可知，互联网使得非法拷贝音乐更容易，故选项C正确。 -

第11题：
问答题Dental Health Decay is not the only disease that can cause tooth loss. Another serious disease affects the gums, the tissue that surrounds the teeth. It is also caused by bacteria. If the bacteria are not removed every day, they form a substance that stays on the teeth. The substance is known as plaque. At first, the gums appear to be swollen, and may bleed when the teeth are brushed. This can lead to serious infection of the tissue around the teeth. The infection may damage the bone that supports the teeth and cause tooth loss and other health problems. Studies have found that people with severe gum disease have an increased risk of developing heart disease, diabetes and stroke. Gum disease can be treated by a special dentist called a periodontist. Periodontists are trained to repair the gum areas that have been damaged. This can be painful and costly. Dental health experts say the best thing to do is to stop gum disease before it starts. The way to do this is to clean the teeth every day. People also should use dental floss to remove plaque from between the teeth. Most experts also agree that another way to prevent tooth and gum problems is to eat foods high in calcium and vitamins and low in sugar. Scientists continue to develop better dental treatments and equipment. Improved technology may change the way people receive dental treatment in the future. For example, dentists are now suing laser light to treat diseased gums and teeth. Dentists use computer technology to help them repair damaged teeth. Researchers have developed improved methods to repair bone that supports the teeth. And genetic research is expected to develop tests that will show the presence of disease causing bacteria in the mouth. Such increased knowledge about dental diseases and ways to prevent them has improved the health of many people. Yet problems remain in some areas. In industrial countries, minorities and other groups have a high level of untreated dental disease. In developing countries, many areas do not have even emergency care services. The World Health Organization says people in countries in Africa have the most tooth and gum problems. World Health Organization experts say the dental health situation is different for almost every country in the world. As a result, it has developed oral health programs separately for each area. The WHO oral health program is mainly for people living in poor areas. It provides them with information about mouth diseases and health care. It also studies preventive programs using fluoride in water, salt, mild and toothpaste. And it explores ways to include dental health in national health care systems. Many governments and other organizations provide help, so people can get needed dental health services. But dental health professionals say people should take good care of their teeth and gums. They say people should keep their teeth as clean as possible. They should eat foods high in calcium and fiber. These include milk products, whole grain breads and cereals, vegetables, fruits, beans and nuts. Recent studies have shown that eating nuts can help slow the production of plaque on the teeth. Experts say these activities will help everyone improve their dental health throughout their lives.正确答案： 【参考译文】
牙齿保健 龋齿并不是唯一一种能对牙齿造成伤害的疾病,还有一种疾病严重影响了牙齿周围的牙龈,它也是由于口腔细菌造成的。如果你不每天清除口腔内的细菌,它们就会在你的牙齿上形成一种叫做牙斑的物质。
起初,牙龈表现为肿胀,刷牙的时候会出血,并会导致牙周组织的严重感染。这种感染可能会伤及支撑牙齿的骨骼,然后造成牙齿脱落或产生其他健康问题。研究表明,严重牙周疾病患者比一般人更容易得心脏病、糖尿病和中风。
牙周病可由专门的牙周病医师来进行治疗。他们一般都接受过正规培训,能够修复牙龈周围受到破坏的部分。但是这一过程比较痛苦而且价格昂贵。牙齿保健专家认为,最好的办法就是提前杜绝牙周炎的发生,方法是每天清洁牙齿。人们可以使用牙线来清除牙齿间的牙斑。多数专家认为,我们还可以通过摄入富含钙及维生素,或是含糖量少的食物以防止牙齿及牙龈疾病的发生。
科学家们正在继续研发更好的牙齿保健及医疗工具。改进后的技术将来可能会改变人们接受牙科治疗的方法。例如,牙医们目前使用激光来治疗损坏的牙龈和牙齿,他们还使用了计算机技术帮助修复损坏的牙齿。研究人员已经找出了修复支撑牙齿的骨骼的方法。一项遗传研究即将展开,它将会证明口腔内存在造成口腔疾病的细菌。
不断增长的牙科疾病知识和预防方法改善了许多人的身体状况,但是在某些地方还存在一些问题。在工业化国家,许多少数民族和其他社会群体中存在数量较多的没有得到治疗的牙科疾病。在发展中国家,许多地区甚至没有紧急医疗中心。世界卫生组织声称,非洲人在牙齿和牙周方面存在更多的问题。
世界卫生组织的专家说,几乎每个国家的牙齿健康状况都不相同,其结果就是每个地方都有各自的口腔保健计划。
世界卫生组织的口腔保健计划主要是针对那些住在贫困地区的人们。该计划为人们提供有关口腔疾病和保健方面的信息,也研究出了多种预防方法,如在水、盐、牛奶和牙膏中添加氟化物。同时,它也探索了把牙齿健康纳入国家健康保健系统的方法。
在许多政府和其他组织提供的帮助下,人们能够得到所需的牙齿健康服务。但是牙齿健康专家表示,人们应该好好照顾自己的牙齿和牙龈。
他们说,人们应当尽量保持牙齿的清洁,并且应该多吃含钙和纤维丰富的食物。包括奶制品、全麦面包及谷类食物、蔬菜、水果、大豆和坚果。近期研究表明,食用坚果能够缓解牙斑的形成。
专家们认为,这些做法将帮助人们改善牙齿状况,使他们终身受益。解析： 暂无解析 -

第13题：
资料：For promotions to remain effective, RT company has to analyze the impact of different campaigns. Word of mouth promotions can be more difficult to measure than some traditional methods of promotion. Although healthy sales are an important measure, RT uses other measures to evaluate the effectiveness of its activities. For example:
Setting targets for sales returns from the smaller promotional activities.
Evaluating the amount of editorial coverage its activities receive in the media.
Measuring the number of blogs related to RT's products and the frequency of comment on these blogs.
Evaluating the online influence of RT activities in the social media. For example, on Twitter there are around 260000 followers of RT activities.On Facebook,more than 21000000 consumers like RT.
Conducting an annual brand health-check with consumers to ensure that they like the brand.
Measuring the outcomes of RT promotions is not just about return on investment. These figures do not create the whole picture. This is because it can be difficult to value word of mouth promotions on paper. Sales returns do not take not account other factors such as longer-term brand loyalty.
What is the passage about?A.the sales report of RT campaigns.
B.the sales report of RT company.
C.how Facebook and Twitter have influenced the market.
D.how to evaluate promotional activities.答案：D解析：本题考查的是主旨大意。
