单选题A study by a group of dentists has concluded that regular use of a certain brand of mouthwash is as effective as flossing in preventing gum disease. The mouthwash company has released a television ad suggesting that people who do not like flossing can now rely solely on mouthwash and brushing to maintain good dental health. A leading manufacturer of dental floss brought a lawsuit against the mouthwash company demanding that the advertisement be discontinued on the grounds that it is misleading.  Which of the following, if true, provides the strongest support for the dental floss company’s claim that the advertisement is misleading?A The dental floss manufacturer is concerned that it will lose market share in the dental health market because the advertisement encourages people to switch from dental floss to mouthwash.B The dental floss company claims in its own advertisements that brushing and flossing after every meal is the most effective way to maintain good dental health.C Although mouthwash is an effective deterrent to gum disease, it is less effective than dental floss at removing plaque and preventing cavities between teeth.D Per usage, mouthwash is three times more expensive than dental floss, if the recommended amounts of both products are used.E The dentists who conducted the study on the effectiveness of mouthwash in preventing gum disease obtained their funding for the study from a company that manufactures mouthwash.

第1题:

A survey has shown that people have stopped believing both the media and politicians. A similar survey carried out 5 years ago showed that 50% of people thought that what politicians said was usually not true, and that 35% of people thought that what they saw on the television or read in newspapers was not true. Now both those figures have increased sharply, to 80% of people not believing politicians and 70% not believing the television or newspapers. Experts think that these figures are not going to come down in the near future.

Stories about politicians and journalists taking money from businessmen have caused the public to stop trusting them. Also politicians keep making promises that they do not keep. Mr Smith of York said, ‘When the politicians make new laws, they only help their friends, not people like me’. Mrs Marley of Leeds said, ‘The newspapers and television are not interested in what is true; they are only interested in money for advertising’.

It has got worse recently as more people can get news from the Internet and learn if the journalists and politicians are telling the truth or not. What can our politicians and journalists do? The only answer is to be more honest.

1.The number of people believing politicians and journalists has __________.

A.increased

B.not changed

C.decreased

2.Experts think this problem ____________.

A.will get better soon

第2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。

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6题:

根据文章内容进行判断,正确写“T”错误写“F”

Brand refers to names, logos and slogans. For example, Nike is known for its slogan “Just do it” and swoosh logo. A trademark shows the origin and ownership of a product or service, which is used to protect names, logos, drawings, symbols and other characters related with a business. Coke? and Coca-cola? are registered trademarks of the Coca-Cola Company.

Many companies spend a lot of money and time registering their trademarks. There are at least two good reasons for this. Firstly, if you trademark a brand, you are the only person allowed to use that Brand name slogan etc. If others want to use that brand, they must ask your permission or pay some money. Secondly, registration also allows the owner to bring legal action against anyone who uses the trademark without authorization.

There are basic trademark symbols, e.g.“TM”for goods and“SM”for service.They tell the public that the product's name and design are the exclusive property of the company, but a registered trademark? provides notice that it has indeed been registered.

( )26. According to the writer, it is not necessary for a company to register a trademark.

( )27. A trademark may be regarded as a protection for a brand name.

( )28. The trademark symbols TM and ? can be exchanged in a brand.

( )29. Legal protection on a brand comes into force only after registration.

( )30. A company can freely use other companies' brands.

第7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.

第9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 piracy

  • A、It has made it easier to fight piracy.
  • B、It has increased the number of pirate CDs available.
  • C、It has made it easier to illegally copy music.
  • D、It has reduced the number of pirate CDs available.
