Organic food, once considered something that only health fanatics desired, is now a regular feature at most supermarkets. And that has created a bit of a dilemma. On the one hand, you have a conventionally grown apple. On the other, you have one that’s organic. Both apples are firm, shiny and red. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol.
Conventionally grown food generally costs less, but is organic food a better choice? The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale. Supporters of organic foods ― a term whose meaning varies greatly ―are frequently telling the world that such products are safer and more nutritious than others.
The growing interest of consumers in the safety and nutritional quality of daily foods is a welcome development. However, much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs.
Almost daily, the public is surrounded by claims for “no-aging” diets, new vitamins and other wonder foods. There are numerous unsubstantiated(没证实的) reports that natural vitamins are superior to man-made ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than those treated with insect spray and the like.
Although most of these claims are not supported by scientific evidence, large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction. As a result, claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have become widely advertised and form the basis for people’s opinion.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the conventional food supply and buy only expensive organic foods instead.According to Paragraph 2, which of the following statements about organic food is true?

Technically the domain name system consists of three parts. First is the addressing system of Internet Protocol(IP)numbers, the 32-bit numbers that are the true addresses of computers connected to the Internet. Next is the naming system, the by-now familiar names that include .com .org .edu .etc., which are collectively known as top level domains, or TLDs. The naming system was devised to find a computer or send email. Finally, there is the routing system, which “maps” domain names to IP numbers. Computers called “root servers” contain a kind of giant directory that links specific names to specific addresses on the Internet.
There are several political headaches about domain names that have no clear solutions. Because domain names have to be unique, they are inevitably linked to trademark disputes when two or more businesses, or people, want the same name.
Domain names also raise issues of privacy. Using a search tool such as the Whonami Global Internet Name Search site, anyone can look up the name and address of whoever is registered as the owner of a domain name.
In 1998, the U.S. government handed over management of the entire domain name system to the Internet Corporation for Assigned Names and Numbers, or ICANN, based in Marina Del Rey. ICANN’s board of directors held one of its periodic general meetings recently in Stockholm, an event that featured an outpouring of frustration and controversy about how the group is managing its new responsibilities.If you want to send email, you must own the following except .
| A．a computer |
| B．the addressing system |
| C．a domain address |
| D．a telephone line or cable |

| D．Search sites help people to get information about domain name owners. |
The purpose of naming system was to .
| A．link specific names to specific addresses on the Internet |
| B．find people on computers. |
| C．distinguish computers or send email |
| D．solve problems for businesses and people |
Domain names which have no clear solutions .
| A．cause people’s headache |
| B．cause difficult situations for the government |
| C．get businesses to change their trademarks |
| D．force businesses to put trademarks on their goods. |
Advertising is as old as story-telling itself. For as long as people have wanted to persuade others to buy their goods, give them their vote or lay down their lives, they have used the methods of advertising. Of course, methods have changed over the years. At first, word of mouth was the only means of communicating, but after the invention of the first printing press and the arrival of the first newspaper, the camera, the television, and the home video recorder, the persuasive methods of the advertising industry have become much more sophisticated.
Advertising appeals more to our emotions than to our minds and therefore uses persuasive techniques which, though not misleading, are certainly biased towards its products. Advertisements have some basic features.
·They are fast and short. They deliver their message in minimum time and space.
·They are concentrated. Their language and images are extremely dense.
·They appeal to consumers’ emotions rather than to their logic.
·They entertain. That entertainment may be in the form of a jazzy melody or a photograph or a clever joke, but it always draws attention to itself because advertisements have to compete against every other competitor for consumers’ attention.In the past, people used methods of advertising when they wanted others to .

Students and Technology in the Classroom
I love my blackberry—it’s my little connection to the larger world that can go anywhere with me . I also love my laptop computer ，as it holds all of my writing and thoughts .Despite this love of technology ,I know that there are times when I need to move away from these devices（设备） and truly communicate with others.
On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas .Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom ,I have a rule —no laptop ,iPads ,phones ,etc .When students were told my rule in advance of the class, some of them were not happy .
Most students think that my reasons for this rule include unpleasant experiences in the past with students misusing technology . There’s a bit of truth to that. Some students think that I am anti-technology . There’s no truth in that at all . I love technology and try to keep up with it so I can relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas . I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course the material and the class discussion .
I’ve been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create .Students realize that with deep conversation and challenge , they learn at a level that helps them keep the course material beyond the classroom .
I’m not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change ,I’m sticking to my plan. A few hours of technology-free （没有科技）dialogue is just too sweet to give up. Some of the students in the history class were unhappy with____
| A．the course material |
| B．others’ misuse of technology |
| C．discussion topics |
| D．the author’s class regulations |
According to the author ,the use of technology in the classroom may ____
| A．keep students from doing independent thinking |
| B．encourage students to have in-depth conversations |
| C．help students to better understand complex themes |
| D．affect students’ concentration on course evaluation |
It can be inferred from the last paragraph that the author ____
| A．is quite stubborn |
| B．will give up teaching history |
| C．will change his teaching plan soon |
| D．values technology-free dialogues in his class |
I grew up in a house where the TV was seldom turned on and with one wall in my bedroom entirely lined with bookshelves, most of my childhood was spent on books I could get hold of. In fact, I grew up thinking of reading as natural as breathing and books unbelievably powerful in shaping perspectives (观点) by creating worlds we could step into, take part. in. and live in.
With this unshakable belief, I, at. fourteen, decided to become a writer. Here too, reading became useful. Every writer starts off knowing that he has something to say, but being unable to find the right ways to say it. He has to find his own voice by reading widely and discovering which parts of the writers he agrees or disagrees with, or agrees with so strongly that it reshapes his own world. He cannot write without loving to read, because only through reading other people's writing can one discover what works, what doesn't and, in the end, together with lots of practice, what voice he has.
Now I am in college, and have come to realize how important it is to read fiction (文学作品)．As a. law student, my reading is in fact limited to subject matter-the volume (量) of what I have to read for classes every week means there is little time to read anything else. Such reading made it all the clearer to me that I live in a very small part in this great place called life. Reading fiction reminds me that there is life beyond my own. It allows me to travel across the high seas and along the Silk Road, all from the comfort of my own armchair, to experience, though secondhand, exciting experiences that I wouldn't necessarily be able to have in my lifetime. What can be inferred about the author as a child?
| A． He never watched TV. |
| B． He read what he had to. |
| C． He found reading unbelievable. |
| D． He considered reading part of his life |
The underlined word "voice" in the second paragraph most probably means "_______".
| A． an idea |
| B． a sound quality |
| C． a way of writing |
| D． a world to write about |
What effect does reading have on the author?
| A． It helps him to realize his dream. |
| B． It opens up a wider world for him. |
| C． It makes his college life more interesting. |
| D． It increases his interest in worldwide travel. |
Which of the following can be the best title of this text?
| A． Why do I read? |
| B． How do I read? |
| C． What do I read? |
| D． When do I read? |
Young adult filmmakers all hope to show their works in international festivals like Sundance and Toronto. But what about really young filmmakers who aren’t in film school yet and aren’t, strictly speaking, eve adults?
They are at the heart of Wingspan Arts Film Festival tomorrow, in a setting any director might envy: Lincoln center. Complete with “red carpet” interviews and various awards, the festival has much in common with events for more experienced moviemakers, except for the age of the participants: about 8 to 18.
“What’s really exciting is that it’s film for kids by kids,” said Cori Gardner, managing director of Wingspan Arts, a nonprofit organization offering youth arts programs in the New York area. This year the festival will include films not only from Wingspan but also from other city organizations and one from a middle school in Arlington, Virginia. “We want to make this a national event,” Ms. Gardner added.
The nine shorts to b shown range from a Claymation biography of B.B. King to a science fiction adventure set in the year 3005. “Ａlot of the material is really mature,” Ms. Gardner said, talking about films by the New York branch of Global Action Project, a media arts and leadership-training group. “The choice is about the history of a family and Master Anti-Smoker is about the dangers of secondhand smoke.” Dream of the Invisibles describes young immigrants’ (移民) feelings of both belonging and not belonging in their adopted country.
