Laptop(便携式) computers are popular all over the world. People use them on trains and air planes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1,500 students at the college will receive a laptop. The laptops are part of a $ 10 million computer program at Westlake, a 100-year-old access to the Internet. In addition, they will be able to use E-mail to "speak" with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast food restaurant or under the tree -- anywhere at all!
Because of the many changes in computer technology, laptop use in higher education, such as, colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable (可携带的) Internet, but also libraries and other re sources. State higher-education officials are studying how laptops can help students. States officials al so are testing laptop programs at other universities, too.
At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, "Here we are in the middle of Virginia and we're giving students a window to the world. They can see everything and do every thing."
The main purpose of the laptop program is to give each student a laptop to ______.
A．use for their schoolwork
B．get access to the Internet
C．work at home
D．connect them to libraries

The Internet raises major issues and challenges for education, not just in China but all over the world. Yet it simply cannot be ignored in terms of the opportunities and resources that it can offer.
We can divide the main issues facing education systems into three groups -- access, quality and responsibility. Let us consider the Internet in relation to each of them.
First, access. Through the Internet, practically the whole world can be brought into your classroom. Using e-mail makes it possible to have a class whose members are spread all over the world and who may never meet either the teacher or each other face to face. It can put students in different countries in easy contact.
The information resources available are almost limitless. With the Internet, students and teachers can access the wisdom, experience, skills, and even guidance of others in a way that was only possible for a very privileged few.
Next, quality. The Internet does pose serious problems of quality for education systems. Obviously, there is a lot of material on the Internet that no one would want children or students to have uncontrolled access to, but there are other problems which are very difficult to solve.
The first is how to handle the sheer quantity of information available, and how to make it manageable.
Because anyone can put information on the Internet, and there are no limits on quantity, it can be almost impossible to find exactly the information that one wants. Teachers and students cannot afford to waste time on unsuccessful searching.
How can we identify the information which will be most useful without overloading ourselves and our Students with unnecessary information？ How do we select the best information from all that is available？
This raises the issue of responsibility. There are few editors or quality controllers on the Internet. The ultimate responsibility for selection and judgment falls to the user, whether teacher or student. Teachers, and still less students, are not experts in every field;what we select may not be what we really want, perhaps is old, even wrong.
Any profession must take some collective responsibility in resolving these problems. Conscious and deliberate efforts have to be made to share information between teachers about useful sites and about the best way to use them.
Those who have found something useful or of high quality should not keep the information to themselves ,but share it as widely as possible.
There are many professional discussion groups active on the Internet which aim to do this. Access to them by teachers should be actively encouraged. This will require investment by institutions in giving easy access to the Internet and email to all teachers. Without this investment, educators --and ultimately students -- will be deprived of a vital resource for the development of education in the future.
第 21 题 With which of the following statements would the author be least likely to agree？
A．The Internet provides us with perfect educational information.
B．The Internet provides us with limitless resources.
C．We can obtain the latest information from foreign countries through the Internet.
D．The information on the Internet is no longer available only for a few people.

I felt that it was perfect chance to up-sell. I checked the booked room with the guest, “Thank you very much for your reliance on our hotel, Mr. Gao. It’s my pleasure to serve you. This time, you have ordered a standard large-bed non-smoking for three nights, right？” “Yes.”
”I suggest you are on a business, right？ I’d like to suggest you try our executive floor. It’s newly decorated, and you will enjoy the top-level service. And there are many preferential treatments.”
“Really？ Then what preferential treatments can I have if I take that？”
“Mr. Gao, you need to use the internet to deal with you business, right？ The Internet service is not free, but you may have one-hour free Internet use each day if you take the ECF. In addition, 80 yuan’s free laundry service, 6 tins of free soft drinks, and so on. And for all of these, you will only need to pay another 20 yuan.”
Here I stopped to observe the reaction of the guest. He kept silence for a while, looking hesitated. Then I said. “Maybe your concern is not how much you will pay, but rather whether the room is worth the price. Would you like to make your decision after having a look at the show room？”
The guest felt very hard to turn down my warm-hearted offer, so he decided to take an executive room for three nights.
30、The guest booked a deluxe room in Lisa’s hotel（）
31、Lisa wanted to earn more money by recommending a higher-priced room（）
32、The guest can use the Internet for free is he takes the executive room（）
33、Lisa really knew why the guest hesitated（）
34、At last, the guest accepted Lisa’s suggestion（）

New Research Lights the Way to Super-fast Computers
(1) New research published today in the journal Nature Communications, has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.＜br＞
(2)The research by the University of Surrey, in collaboration with the University of Cambridge and the University of Southampton, has found it is possible to change the electronic properties of amorphous chalcogenides, a glass material integral to data technologies such as CDs and DVDs.＜br＞
By using a technique called ion doping, the team of researchers have discovered a material that could use light to bring together different computing functions into one component, leading to all-optical systems.＜br＞
(3)Computers currently use electrons to transfer information and process applications. On the other hand, data sources such as the Internet rely on optical systems; the transfer of information using light. Optical fibers are used to send information around the world at the speed of light, but these signals then have to be converted to electrical signals once they reach a computer, causing a significant slowdown in processing.＜br＞
(4) "The challenge is to find a single material that can effectively use and control light to carry information arotmd a computer. Much like how the web uses light to deliver information, we want to use light to both deliver and process computer data," said project leader, Dr Richard Curry of the University of Surrey.＜br＞
(5) "This has eluded researchers for decades, but now we have now shown how a widely used glass can be manipulated to conduct negative electrons, as well as positive charges, creating what are known as &39;pn-junction&39; devices. This should enable the material to act as a light source, a light guide and a light detector -- something that can carry and interpret optical information. In doing so, this could transform. the computers of tomorrow, allowing them to effectively process information at much faster speeds."＜br＞
(6) The researchers expect that the results of this research will be integrated into computers within ten years. In the short term, the glass is already being developed and used in next-generation computer memory technology known as CRAM, which may ultimately be integrated with the advances reported.＜
