    根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    Most drinks stating that they are fruit-flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.

    “Shoppers need to check the labels (标签)before buying drinks, though sometimes the actual content can be non-existent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive.    1   It will increase profits, and consumers won’t always realize they are being tricked.”

    Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry-flavored products sold in stores.    2   Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.

       3   Let’s take jam as an example. Some strawberry-flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.

       4   Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading.    5   Unfortunately, it is also legal and widespread,” Tokelove said. “It’s time to take measures to protect the consumers’ rights.”

    A．The products which contain real fruit are popular with people.

    B．Even products advertised as more natural often contained no fruit.

    C．They found that about 60 percent of them didn’t contain any fruit at all.

    D．If companies can cut their costs by using flavoring, they are likely to do so.

    E. It is important and necessary to demand a small amount of flavoring in the products.

    F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.

    G. The Food Commission suggested all flavors used in a product should be listed on the packaging.

    SECTION B (10 points )

    Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.

    The average college student in America spent an estimated 700 dollars on textbooks last year. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials.

    Association spokesman Charles Schmidt says electronic textbooks now represent just two to three percent of sales. But he says that is expected to reach 10 to 15 percent by 2012.

    Online versions are now available for many of the most popular college textbooks. E-textbooks can cost half the price of a new print textbook. But students usually lose access after the end of the term. And the books cannot be placed on more than one device, so they are not easy to share.

    So what do students think of e-textbooks? Administrators at Northwest Missouri State University wanted to find out. Earlier this year they tested them with 500 students in 20 classes.

    The students in the survey reported that downloading the books from the Internet was easy. They liked the idea of carrying lighter backpacks. And 56 percent said they were better able to find information.

    But most found that using e-textbooks did not change their study habits. And 60 percent felt they read more when they were reading on paper. In all, almost half the students said they still liked physical textbooks better.

    But the survey found that cost could be a big influence. 55 percent said they would choose e-textbooks if using them meant their textbook rental fee would not increase.

    Roger Von Holzen heads the Center for Information Technology in Education at Northwest Missouri State. He tells us that administrators are disappointed with the e-textbooks now available because the majority are not interactive.

    He thinks growth will come when more digital books include video, activities, games and other ways to interact with the information. The technology is improving. But for now, most of the books are just words on a screen.

    81. How much do the average college student in America spend on textbooks last year? （no more than 4 words）

    ______________________________________________________________________________

    82. What is the percentage of the e-textbook sales now according to Charles Schmidt? （no more than 4 words）

    ______________________________________________________________________________

    83. What do students think of downloading the books from the Internet in the survey? （no more than 2 words）

    ______________________________________________________________________________

    84. Why are administrators disappointed with the e-textbooks now available? （no more than 6 words）

    Nowadays people use different ways to communicate with each other. And does one always tell the truth when he or she talks with the other on the phone? Or does one sometimes tell a lie when writing an e­mail or giving an instant message? Recent research has found that communication technologies are far from equal when it comes to conveying the truth. The first study, made by Jeff Hancock of Cornell University in Ithaca，New York, to compare honesty across a range of communication media has found that people are twice as likely to tell lies in phone conversations as they are in e­mails. The fact that e­mails are automatically recorded—and can come back to trouble you—appears to be the key to the finding.

    Jeff Hancock made an investigation by asking 30 students to keep a communication diary for a week. In it they noted the number of conversations or e­mail exchanges they had lasting more than 10 minutes, and how many lies they told. Hancock then worked out the number of lies per conversation for each medium. He found that lies made up 14 per cent of e­mails,21 per cent of instant messages, 27 per cent of face­to­face interactions and an astonishing 37 per cent of phone calls.

    His results, to be presented at the conference on human computer interaction in Vienna, Austria, in April, have surprised psychologists. Some expected e­mailers to be the biggest liars, reasoning that because the unreal condition makes people uncomfortable,  the detachment of e­mailing would make it easier to lie. Others expected people to lie more in face­to­face exchanges because people are more practiced at that form of communication.

    But Hancock says it is also very important and effective whether a conversation is being recorded and could be reread，and whether it occurs in real time. People appear to be afraid to lie when they know that they will be responsible for what they have said in the conversation, he says. This is why fewer lies appear in e­mails than on the phone.

    People are also more likely to lie in real time—in an instant message or phone call, say—than if they have time to think of a response, says Hancock.  He found many lies are sudden or immediate responses to demands that they don’t expect, such as “Do you like my dress？”

    Hancock hopes his research will help business companies work out the best ways for their employees to communicate.For instance, the phone might be the best medium for selling their products where employees are encouraged to stretch the truth. But when giving results, work assessment, where honesty is regarded as more important than others, it might be best by using e­mails.

    Jeff Hancock’s study on lying in different ways of communication

    The 71.__________from the statistics of the investigation

    People tell 72.________lies when the communicating ways change from 73.________to instant messages to face­to­face interactions to phone calls.
