Many businesses today use conferences as a means of discussing new plans for company. As people are paying more attention to the environment and green problems, more businesses are looking for ways to reduce their negative effect on the environment. Many businesses do this by using web conferencing.
Web conferencing is a technology that allows people to communicate more effectively over the Internet. It is an easy way of hosting and attending conferences without having to leave the office. Each of the people involved in a web conference will be posted an invitation to the conference with the time and date of the web conference on it. When the conference is ready to begin, all participants (參與者) must sit at their computer and they will be connected over the Internet.
Obviously, in doing this no fuel is used in traveling to and from a conference, and less work time is taken up in attending a conference.
Any material to be used during the web conference is simply e-mailed to all the participants before the conference. This not only saves paper but also greatly reduces mailing cost for the business.
As a conference hall or business center isn’t being used, it means that the only power that is used is the power used by the participants’ personal computers. Similarly conference organizers don’t have to arrange for food or overnight accommodation (住宿) for participants. All this means that less energy is used.
Many companies actively do many things to reduce their negative impact (影響) on the environment. So web conferencing is much cheaper and greener and more people are willing to host and attend a web conference.
小題1:What is the passage mainly about?
A．Ways of protecting the environment.
B．Green benefits of web conference.
C．Ways of hosting a web conference.
D．Impacts of web conferencing on costs.
小題2:According to paragraph 1, many companies use web conferencing because they________.

B．believe that web conferencing is more convenient
C．want to do something to protect the environment
D．haven’t enough money to hold a traditional conference

No one would be willing to pay one-third of the price for the packaging or wrapping of what he or she purchases. But over-packaging has become a disease that leads to an __50__ waste of resources and __51__ environmental pollution.
The wasted packaging materials are __52__ to be worth about 280 billion yuan annually. And such packages and wrappings thrown away by customers __53__ up half of the volume of solid waste in cities. __54__, it is high time that regulations were __55__ to stop enterprises from spending too much on unnecessary packaging and wrapping.
To produce paper packaging or wrapping, many more trees have to be cut down. Over-packaging also limits the interest of consumers when they have to spend quite a high percentage on something that they will have to throw into the dustbin. The simple truth is that the more a producer spends on packaging, the __56__ the products it sells will be.
Product packaging and wrapping used to be very simple 30 years ago. "Shabby" was the word many had used to __57__ the way Chinese products were packaged. And shabby packaging was blamed for making Chinese products __58__ in the international market.
It is __59__ to pay enough attention to packaging or wrapping products in such a manner that they can be __60__ to customers' eyes. But that does not definitely justify that packaging should even outshine what is inside.
In the Chinese proverb, “maidu huanzhu,” the buyer returns the pearl and just keeps the case because the __61__ is too fancy and luxurious. It not only laughs at the poor __62__ of the buyer, but also criticizes the unnecessary __63__ the seller has made in making the case. Another message from the proverb is that over-packaging helps cultivate an __64__ consuming attitude - to buy fancy-looking stuff but not what they really need.

Unlike Britain, the US does not have a national health care service. Most people buy medical insurance to help pay for medical care. The government only helps pay for some medical care for the old and the people who are on low incomes. The problems of those who cannot afford insurance have become an important political subject.
In Britain, when people are ill, they usually go to a family doctor first. However, people in America sometimes go straight to an expert. Children are usually taken to a doctor who is an expert in the treatment of children. In Britain, if a patient needs to see a specialist doctor, their family doctor will usually recommend a specialist, which will save more time and money both for the patients and the public fund（基金）.
In Britain, doctors do not go to people’s homes when they are ill. People always make appointments to see the doctor in the doctor’s office. In a serious situation, people call for an ambulance. In America, hospitals must treat all seriously ill patients, even if they do not have medical insurance. The gov-ernment will then help pay for some of the cost of the medical care.

Many people seem to think that science fiction is typified by the Bug-eyed Monster, embodying every feature that most people find unpleasant. This is unfortunate because it degrades a worthwhile literary endeavor. Instead, the basic interest of science fiction lies in the relation between man and his technology and between man and the universe. Science fiction is a literature of change and a literature of the future, and the aspects of human life that it considers make it well worth reading and studying for no other literary form does quite the same things. What is science fiction? To begin, the following definition should be helpful: science fiction is a literary subgenre which postulates(以…為前提) a change (for human beings) from conditions as we know them and follows the implications of these changes to a conclusion.?
The first point that science fiction is a literary subgenre is a very important one, but one which is often overlooked. Specifically, science fiction is either a short story or a novel. There are only a few dramas which could be called science fiction; the body of poetry that might be labeled science fiction is only slightly larger. To say that science fiction is a subgenre of prose fiction(小說(shuō)) is to say that it has all the basic characteristics and serves the same basic functions in much the same way as prose fiction in general, that is, it shares a great deal with all other novels and short stories.
Everything that can be said about prose fiction, in general, applies to science fiction. Every piece of science fiction, whether short story or novel, must have a narrator, a story, a plot, characters, setting, and language. The themes of science fiction are concerned with interpreting man’s nature and experience around him. Themes in science fiction are constructed and presented in exactly the same ways that themes are dealt with in any other kind of fiction. They are the result to a particular combination of a narrator, story, plot, character, setting, and language. In short, the reasons for reading and enjoying science fiction, and the ways of studying and analyzing it, are basically the same as they would be for any other story or novel.?
51.From the first paragraph, we can infer that science fiction has been most popular in the 20th century because ____.?
A with the growth of literacy, the size of the reading public has increased?
B competition from television has created a demand for more exciting fiction?
C science fiction is easier to understand than other kinds of fiction?
D the increased importance of technology has given science fiction an increased relevance
52.According to the definition in the passage, a fictional work that places human beings in a prehistoric world inhabited by dinosaurs____.?
A cannot be called science fiction because it does not deal with the future?
B cannot be called science fiction because it doesn’t deal with technology?
C can be called science fiction because it deals with man’s relation with the world?
D can be called science fiction because it places people in an environment different from the one we know?
53. Science fiction is called a literary subgenre because____.?
A it is not important enough to be a literary genre?
B it cannot be made into a dramatic presentation?
C it shares characteristics with other types of prose fiction?
D it has its limits?
54.One implication of the final sentence in the passage is that____.?
A the reader should turn next to commentaries on general fiction?
B there is no reason for any reader not to like science fiction?
C the reader should compare other novels and stories to science fiction?
D those who can appreciate prose fiction can appreciate science fiction?
55.An appropriate title for this passage would be____.?
A Man and the Universe?
B Toward a Definition of Science Fiction?
C A Type of Prose Fiction?
D The Bug-Eyed Monster??

Few of us make money by losing sleep．But three graduate students at Brown University in Providence built a company around sleep deprivation （睡眠不足）．
Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools．They began thinking about ways to sleep better．They discovered they weren't alone in burning the midnight oil．Around 20% of Americans get less than six hours of rest a night．
The friends imagined a smart alarm clock that could track how much time people spend in the most restorative （有回復(fù)作用的） stages of the sleep cycle: REM （rapid eye movement） and deep sleep．What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists．
Their company, Zeo, based in Newton, Mass, launched its product in June, 2009．The Zeo device uses a headband with tiny sensors （傳感器） that scan your brain for signs of four sleep states- REM, light, deep and waking sleep．The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep （which is when you're least groggy）．In the morning you can upload the data to the company's Web site, and so track your sleep over time．Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept．
"Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO．
Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm．
For now the company is selling Zeo online only．Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels．
小題1:Who will support Zeo?
A．People full of imagination．B．People suffering sleeping problems．

In the last few years the Internet has become a widespread phenomenon(現(xiàn)象) around the world. People have started to use the computers just like they used to watch TV. Whenever we get hungry, we simply order a pizza through the Internet and while we are waiting for the food, we can send an important business e-mail concerning some sales for tomorrow.

Sometimes when you are sad and are feeling lonely, if you go on the Internet, you can find good entertainment that will keep you busy.

This year 2,300 teenagers ( young people aged from 13-19 ) from all over the world will spend about ten months in U.S. homes. They will attend U.S. schools, meet U.S. teenagers, and form impressions (印象) of the real American teenagers. American teenagers will go to other countries to learn new languages and have a new understanding of the rest of the world.
Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George's family. In return, George's son, Mike, spent a year in Fred's home in America.
Fred, a lively young man, knew little German when he arrived, but after two months study, the language began to come to him. School was completely different from what he had expected — much harder. Students rose respectfully (尊敬地) when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
Family life, too, was different. The family's word was law, and all activities were around the family rather than one of the members. Fred found the food too simple at first. Also, he missed having a car.
“Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”
At the same time, in America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize (批評(píng)) American schools.” he says. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens. There ought to be some middle ground between the two.”
小題1:The whole exchange program is mainly to ____.
A．help teenagers in other countries know the real America
B．send students in America to travel in Germany
C．let students learn something about other countries
D．have teenagers learn new languages
小題2:What did Fred and Mike agree on?
A．American food tasted better than German food.
B．German schools were harder than American schools.
C．Americans and Germans were both friendly.
D．There were more cars on the streets in America.
小題3: What is particular (特別的) in American schools?
A．There is some middle ground between the two teaching buildings.
B．There are a lot of after-school activities.
C．Students usually take 14 subjects in all.
D．Students go outside to enjoy themselves in a car.
小題4:What did Mike think after experiencing the American school life?
A．A better education should include something good from both America and Germany.
B．German schools trained students to be better citizens.
C．American schools were not as good as German schools.
D．The easy life in the American school was more helpful to students.

“Life is speeding up. Everyone is getting unwell.”
This may sound like something someone would say today. But in fact, an unknown citizen who lived in Rome in AD 52 wrote it.
We all love new inventions. They are exciting, amazing and can even change our lives.
But have all these developments really improved the quality of our lives?
Picture this: You’re rushing to finish your homework on the computer. Your mobile phone rings, a QQ message from your friend appears on the screen, the noise from the television is getting louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have to stay up all night to get it done. How calm and happy do you feel?
Inventions have speeded up our lives so much that they often leave us feeling stressed and tired. Why do you think people who live far away from noisy cities, who have not telephones, no cars, not even any electricity often seem to be happier? Perhaps because they lead simpler lives.
One family in the UK went “back in time” to see what life was like without all the inventions we have today. The grandparents, with their daughter, and grandsons Benjamin, 10, and Tomas, 7, spent nine weeks in a 1940s house. They had no washing machine, microwave, computer or mobile phones.
The grandmother, Lyn, said, “It was hard physically, but not mentally.” She believed life was less materialistic. “The more things you have, the more difficult life becomes,” She said. The boys said they fought less to fight over, such as their computer. Benjamin also noticed that his grandmother had changed from being a “trendy（時(shí)髦的）, beer-drinking granny, to one who cooked things.”
Here are some simple ways to beat the stress often caused by our inventions!
Don’t be available all the time, turn off your mobile phone at certain times of the day. Don’t check your e-mail every day.
Don’t reply to somebody as soon as they leave a text message just because you can. It may be fun at first, but it soon gets annoying.
小題1:The passage is mainly about         .
A．problem with technology
B．improvements of our life with technology
C．the important roles technology plays in our everyday life
D．major changes which will be likely to happen to technology
小題2:The writer quoted（引用） what a citizen in ancient Rome said at the beginning of the story in order to         .
A．share a truth about life
B．tell us what life was like long time ago
C．make us wonder what causes such a thing to happen
D．point out that you experience some big problems and they may be the same
小題3:Why did the family choose to spend some time in a 1940’s house? Because       .
A．they liked to live simple lives
B．they were curious about how people lived without modern inventions
C．they were troubled by modern inventions
D．living in a different time would be a lot of fun for them
小題4:What do you think the underlined word “available” in the 1st suggestion offered by the writer mean?
A．Busy on lineB．Free.C．Be able toD．Be found by others.
