Last year college students in America spent an estimated $700 on textbooks on average. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials.
The association spokesman Charles Schmidt says electronic textbooks now just make up 2%~3% of sales. But he says that is expected to reach 10%~15% by 2012.
Online versions(版本) are now available for many of the most popular college textbooks. An etextbook can cost half the price of a new print textbook. But students usually lose access to them after the end of the term. And the books cannot be placed on more than one device(设备),so they are not easy to share.
So what do students think of etextbooks?Administrators at Northwest Missouri State University wanted to find it out. Earlier this year they tested them with 500 students in 20 classes.
The university is unusual. It provides laptop computers for all 7,000 of its fulltime students. It does not require students to buy their textbooks either. They rent them to save money. The school aims to save even more by moving to etextbooks.
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% said they were better able to find information.
But most found that using etextbooks did not change their study habits. And 60% 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% said they would choose etextbooks 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 University. He tells us that administrators are disappointed with the etextbooks now available because the majority are not interactive(交互式的).
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.
Etextbooks are not better than paper books in that________.

A.they cost more money
B.they’re difficult to carry
C.they’re not convenient to share
D.they can’t be downloaded from the Internet

How many surveyed students think paper books make better reading?

A.60%. B.56%. C.55%. D.50%.

It can be inferred from the text that in the future________.

A.digital books will be more popular
B.the digital books available need improvement
C.free digital books are available online
D.digital books will replace print textbooks

A sign can be found in the front yard of a house in the US. The people living here want to let their dog play outside and ensure it won’t run into the street. So, they hire a company to set up an “invisible fence”, an electric wire buried in the ground around the yard. The dog wears a special collar and when it walks near to the “fence”, the wire will send out a small shock. The dog quickly learns to stay away from the edge of the yard. As it says at the bottom of the sign, the fence will keep your dog “safe” (away from the street) and “at home” (contained inside the yard).
The small word “BRAND” printed in blue means that “Invisible Fence” is registered as the company’s brand name. Similarly, the “TM” printed after “your dog safe at home” stands for “trade mark”, a slogan registered specifically to one company.
The people set up an “invisible fence” _________.

A.to let their dog play outside their house
B.to keep their dog away from the edge of the yard
C.to keep their dog inside their yard
D.to warn others not to enter their house

A.The fence does not exist at all.
B.The “Invisible Fence” is the name of a company.

Imagine living locked inside a closet.You can’t choose when and what to eat or how you will spend your time.You can’t even decide when the lights go on and off. Think about spending your whole life like this.
This is the life of lab animals.
Now consider the needs of these animals.Chimpanzees(黑猩猩),in their natural homes,are never separated from their families.They spend hours together every day.But in a lab,chimpanzees are put in cages alone.There are no families,only cold,hard cages,and loneliness that goes on for so many years that most of them lose their minds at last.
Worse yet are the experiments.Animals are given diseases they would never normally get.Experimenters force-feed(给……强行喂食) chemicals to them,conduct repeated surgeries(手术),and much more,Think of what it would be like to put up with these and then be thrown back into a cage,usually without any painkillers.Often animals see other animals being killed right in front of them.
Hundreds of thousands of animals are poisoned,blinded,and killed every year in product tests for shampoos,skin creams and new cancer drugs.Although more than 500 companies have stopped testing on animals,some of them still force chemicals into monkeys’ stomachs and rabbits’ eyes.
Although some facilities are better than others at caring for animals—not every lab worker kills a mouse by cutting off its head with scissors—there are no happy animals inside laboratories.Will the lab life end? When will it end?

Taking the train is a wonderful way to see America.In the 19th century,train routes appeared from coast to coast,carrying both people and goods Today,a long-distance Amtrak train trip is a different way to experience the United States.
The long-distance Amtrak trains have lots of room.Coach seats have lots of leg room and wide aisles(走廊),sightseeing lounges(休闲室) have large windows,and sleeping areas can provide a good night’s rest.On a train trip,there’s time to talk,play cards or board games,and read to one another.On a car trip,parents have to drive while on a train,parents can sit back and watch the scenery go by.Unlike an airplane,traveling by train is not the quickest way to arrive at your destination;the train is the destination in itself.
Amtrak manages long-distance trains that run through the United States.Routes have different names,such as Empire Builder,California Zephyr,Sunset Limited and Southwest Chief.The long-distance trains have double-decker cars(Superliners), sightseeing lounges, and a real dining car.On shorter trains,such as from New York to Washington.DC,the cars are single level and only have a snack bar.In the Superliner trains,the sightseeing lounge is lined with windows on the second level while on the lower level a snack bar and tables can be found.In the evening,videos are shown in the lounge car—either entertaining movies or documentaries.
Tip:As delays are common on Amtrak trains,always call the station before you go there.Otherwise,you may be cooling your heels(脚后跟) for hours.
