copy. It charges libraries per book per copy and gives publishers a cut of the total income.
From the consumer"s (消费者) point of view, this means that if more than, say, five people want the latest
Danielle Steel romance novel, other people who request that book will get a message saying the title is
unavailable.
It"s a model many publishers seem to have embraced. More than 350 gave the company rights to hand out
their digital works, and McGraw-Hill Corporation and Houghton Mifflin Corporation have put money in the
company. The California public libraries and about 1, 800 others across the US are trying out the Net Library
service.
Some librarians criticize the New Library model. Stanford University librarian Michael Keller argues that the
company is creating an unnatural fear of digital works, which is contrary to the ideas of the Internet.
Keller and some other librarians argue for the e-book vision set forth by EBrary. EBrary is starting a service
that lets us users read books for free.
But it will charge about 25 cents a page when a person tries to print out material or copy and paste it into a
different file or tries to download a copy onto a computer.
Christopher Warnock, chief executive of EBrary, believes most consumers won"t want to buy entire books,
only the parts that interest them.
"There"s not really a lot of good in owning an electronic file and having to store it and manage it. It doesn"t
make sense," he said.
B. They share the money with the Net Library.
C. They get money by cutting the cost of the books.
D. They get the money from the readers.
B. held something tightly
C. disliked something badly
D. tried out something hard
B. enjoy the service of the Net Library
C. don"t like other people borrowing books
D. complain about the limited number of the new books
B. There is no need for consumers to have a whole book.
C. EBrary is not a good library for the consumers.
D. It"s reasonable to charge the consumers money for copying some pages.

Internet. However, you can also find many weather signs among wildlife, because of their highly developed
senses. Drops in air pressure (压力) produce an effect on small animals in many ways. Mice and deer are
good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field
mice come out of their holes and run around. Deer leave high ground and come down from the mountains.
Birds are especially good weather indicators because they also show the effect of a pressure drop in many
ways. For example, some birds become irritable (急躁的) and quarrelsome and will fight over a piece of bread.
Other birds chirp (叽叽喳喳) and sing just before a storm. It seems they know they won"t get another chance
for an hour or two. Birds also seek safe places before a storm. You will sometimes see birds settling in trees
or gathering together on a wire close to a building. Pre-storm low pressure makes the air so thin that birds
have difficulty flying.
It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the
spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may
be flying ahead of a storm.
By paying closer attention to some important signs in nature, we can become better prepared for any kind
of weather.

hardly know a time when computers weren"t around, and they eagerly catch the chance to spend hours online,
chatting with friends, So what?
But researchers nationwide are increasingly worried that teens are becoming isolated (孤寂), less skillful at
person-to-person relationships, and perhaps numb (麻木) to the cheatings that are so much a part of the e-mail
world. "And a teen"s sense of self and values may be changed in a world where personal connections can be
limitless,"said Sherry Turkle.
Another researcher, Robert Kraut, said he"s worried about the "opportunity costs" (机会成本) of so much
online time for youths. He found that teens who used computers, even just a few hours a week, showed
increased signs of loneliness and social isolation. "Chatting online may be better than watching television, but
it"s worse than hanging out (闲逛) with real friends," he said.
Today"s teens, however, don"t see anything strange in the fact that the computer takes up a central place in
their social lives, "School is busy and full of pressure. There"s almost no time to just hang out." said Parker Rice,
17. "Talking online is just catch-up time."
Teens say they feel good about what they say online or taking the time to think about a reply. Some teens
admit that asking someone for a date, or breaking up, can be easier in message form, though they don"t want
to do so. But they insist there"s no harm.

when writing book reports and stories, I use Microsoft Word instead of a pen and paper. That way, after my
teacher edits my work, I can go back and make revisions without having to rewrite the whole thing. And
Microsoft Word has a spell checks! I use it all the time.
For English class, we"re reading The Outsiders, by S.E.Hinter. As a pre-reading assignment, my teacher
asked us to research teenage groups on the Internet. I tried Google, Encarta, and Yahoo first, and finally
found an article on Time.com.
For a geography assignment on the United States, I used Encarta to learn about the Mississippi River. I
needed to find out how deep the river is, how its widths and depths are different, what states it runs through,
and what kind of fish live in it. I used the information to show how the geography of a country affects its
economy. For example, the river"s trade paths, the number offish caught in it, and the tourists it attracts
directly affect Southerners" jobs and incomes.
I never go to the library to do research. It takes too much time. Since I live in New York City and both
my parents work, getting to the library isn"t always easy. For a big assignment or research project, I"d have
to stay at the library to read, or sign out whatever books or magazines I needed. Being able to find the
information in my own living room makes everything a lot simpler. Online dictionaries and encyclopedias also
save time.
Sometimes. I think the computer spoils my generation because it"s so easy at least physically. But
computers are not like television, which does the thinking for you. You still have to use your mind. I prefer
using a computer. Easy, fun, and fast.

Did you ever wonder why the water level in a glass doesn"t change when the ice in the glass melts (融化)?
To find out why, you can use the scientific method. Used by scientists in various situations, the scientific
method is also a clear and logical way to solve many real-world problems, as the procedure below indicates.
| Steps in the Scientific Method | Examples |
| State the problem or question. | "Why doesn"t the water level in a glass rise when ice melts?" |
| Collect information about the problem, using your own observations and research. | You already know that ice is frozen water. From your research, you learn that water and ice are made of water molecules (分子). |
| Form a hypothesis, or a best guess based on the information. | "The molecules in water appear to be closer together than they are in ice." |
| Test the hypothesis by doing an experiment. | Fill four glasses with ice. Then pour water over the ice and fill each glass to the rim. As the ice melts, you observe that the water does not spill over the top of the glasses. Each time you repeat the experiment, you get the same results. |
| Draw a conclusion based on your results. | Molecules are closer together in water than they are in ice. |

| Dogs wag (摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found. Researchers in Italy examined the tail wagging behavior of 30 dogs, catching their responses to a range of stimuli (刺激物) with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time. The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners-a positive experience-their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appears of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Research ers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood (心情) of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach. | |
