阅读理解。     From the jagged (锯齿状的) peaks of the Himalayas to the powerful Yangtze River that flows into the Pacific, China"s vast terrain (地带) and varied climate make it the sixth most biologically diverse nation on
the planet.
     Since 1998, The Nature Conservancy has been working in China"s northwest Yunnan Province to
protect some of the amazing natural and cultural diversity unique to this country for its future generations. In cooperation with Chinese local and state government agencies, the Conservancy established the Yunnan
Great Rivers Project, which protects an area about the size of West Virginia.
     Did you know?
     ●China contains 10% of the world"s total species.
     ●At least 15% of China"s mammal species and 8% of its bird species are found nowhere else on
Earth.
     ●Nearly 15,000 plant species are native to Yunnan Province.
     ●Yunnan is home to 75% of Tibetan medicinal herbs and 30 endangered species.
     What is the Nature Conservancy trying to do?
     Education for Sustainability (可持续性)
     The Nature Conservancy recognizes that environmental education is an important element of working
closely with local communities to achieve sustainable conservation results. In response, the Conservancy
launched a new program called Education for Sustainability which tests means of teaching and learning that combine conservation goals, social justice, and appropriate development and participation in a vision and mission for personal and social change.
     Promoting Green Tourism
     Tourism is both an environmental threat and an economic opportunity, with the potential to provide
extremely needed income to northwest Yunnan. The Conservancy is working with local communities,
government agencies, and tourism ,enterprises(企业) to develop strategies for "green" tourism which will
limit the footprint of mass tourism while generating income for local people. In addition to combining

阅读理解。     In the 1960s, people asked about your astrological sign(星相). In the 1990s, they wanted to know
your website (网址). These days, having a web address is almost as important as a street address.
Your website is an electronic meeting place for your family, friends and potentially, millions of people
around the world. Best of all, you may not have to spend a cent. The Web is filled with all kinds of
free services and all it takes is some time and creativity.
      Think of your home page as the starting point of your website. Like the table of contents of a
book or a magazine, the home page is the front door. Your site can have one or more pages, depending
on how you design it.
      While web pages vary greatly in their design and content, most use a traditional magazine layout
(版面设计). At the top of the page is a banner(大标题) GRAPHIC. Next comes a greeting and a
short description of the site. Pictures, texts, and links to other websites follow.
      Before you start building your site, do some planning. Think about whom the site is for and what
you want to say. Next, gather up the material that you want to put on the site. Draw a rough layout
on a sheet of paper.
      While there are no rules you have to follow, there are a few things to keep in mind:
      Start simply  If you are too ambitious (雄心勃勃的) at the beginning, you may never get the site
off the ground. You can always add to your site.
Less is better  Most people don"t like to read a lot of text online. Break it into small pieces.
      Smaller is better  Most people connect to the Internet with a modem (调制解调器). Since it can
take a long time to download large image files, keep the file sizes small. Have the rights  Don"t put any
material on your site unless you are sure you can do it legally (合法地). Learn the Net"s Copyright
Article for more about this.
      Now it"s time to roll up your sleeves and start building. Learning the Net Communities provides
tools to help you build your site. 1. The main purpose of the passage is to tell you _____.A. what a website is like     
B. how to build your own website
C. how to meet people online   
D. what a website is made up of2. According to the writer, your website is a place _____.   A. where you can meet people all around the world
B. where you can buy what you want
C. where you can get free services
D. where you can meet people on the Internet 3. The purpose of the home page of your website is _____.  A. to give a list of all the contents of your website
B. to make it look like a front door
C. to direct people to more of your pages
D. to design the cover of a book or magazine4. The writer thinks that if you are too ambitious at the beginning, _____. A. your website may leave no space for adding new things
B. you may never have your website working
C. you may have no idea how to build your website
D. you may tire yourself out

      After almost 30 years of arguing that a black hole swallows up everything that falls into it, British
astrophysicist (天体物理学家) Stephen Hawking moved backward last week.
      The world-famous writer of "Brief History of Time" said he and other scientists had got it wrong.  
     "I"ve been thinking about this problem for the last 30 years, and I think I now have the answer to it,"
said Hawking. "A black hole only appears to form but later opens up and set free information about
what fell inside. So we can be sure of the past and can predict the future."
      The findings could help solve the "black hole information paradox(似是而非的观点)", an important
puzzle in modern physics.
      A black hole is an area in space where matter is under such pressure that even light can not escape
from its gravitational pull(引力). But, exactly what happens there has long puzzled scientists.
      Black holes occur when a powerful star burns up its nuclear fuel and gravity forces it to break down
in on itself. The great weight of the star"s outer layers moves in towards its center. The force of gravity
keeps nearly all light from escaping and nothing inside can be seen from the outside.
      The star actually disappears from the universe into a point of infinite density(高密度). That is a place
where the laws of general relativity that govern space and time break down.
     Hawking has devoted most of his life to studying these questions.
     At the beginning, cosmologists believed the holes were like a "universal vacuum (真空) cleaner",
sucking up everything in their path.
      Hawking revolutionized the study of black holes when he proved, in 1976 that, under the strange
rules of quantum physics(量子物理), when black holes form they send out energy and lose mass in the
process.
      In thinking up this so-called "Hawking radiation", the Cambridge mathematician also created one of
the biggest puzzles in physics.
      These particles (粒子), he said, contained no information about what has been occurring inside the
black hole, or how it formed. Under his theory, once the black hole disappears, all the information within
it is lost.1. What"s the importance of Hawking"s new findings?    A. They could help solve the puzzle about black holes.
B. They has solved the mystery of "black holes".
C. We can now know what is going on inside "black holes".
D. Scientists have already predicted the future of "black holes" now.2. What"s the meaning of the underlined word "cosmologist" (in Paragraph 9)?  A. A person who studies the universe and its origin and development. 
B. A person who studies the stars and their development.
C. A person who travels in a spacecraft.
D. A person who studies the position of the stars and the movements of the planets.3. Which of the following is TRUE?  A. Hawking has now studied black holes for more than 40 years.
B. During the course of the black hole"s forming the enormous weight of the star"s center
moves into the outer layers.
C. Almost nothing can escape from the gravitational pull of the black hole.
D. Scientists have been thinking the black hole contains no information.4. What would be the best title for the passage?  A. The Formation of the Black Hole 
B. Black Hole Information Paradox
C. Black Hole Mystery
D. The Cause of the Black Hole

阅读理解。      Man is a land animal, but he is also closely tied to the sea. Throughout history the sea has served
the needs of man. The sea has provided man with food and a convenient way to travel to many parts
of the world. Today, nearly two-thirds of the world"s population live within 80 kilometers of the sea
coast.
      In the modern technological world, the sea offers many resources to help mankind survive.
Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many
of man"s needs.
     The list of riches of the sea yet to be developed by man"s technology is impressive. Oil and gas
explorations have been carried out for nearly 30 years. Valuable amounts of minerals exist on the
ocean floor ready to be mined.
     Fish farming promises to be a good way to produce large quantities of food. The culture of fish
and shellfish is an ancient skill practiced in the past mainly by Oriental people.
     Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm
temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents
and waves offer possible use as a source of energy.
     Technology is enabling man to explore ever more deeply under the sea. The development of
strong, new materials has made this possible.
     The technology to harvest the sea continues to improve. Experts believe that by the year 2050
the problems that prevent us from exploiting fully the food, minerals, and energy sources of the sea
will be largely solved.1. What is the beat title for the passage?A. Needs of Man.              
B. Sea Harvest and Food
C. Sea and Sources of Energy    
D. Sea Exploring Technology.2. It can be inferred from the passage that ______.A. man hasn"t completely made use of the riches of the sea
B. technology for exploring the sea has been solved
C. harvesting rice in the sea will be made possible
D. in the near future man can live on the ocean floor3. Why does the author mention a steamship in paragraph 5?A. To illustrate that man can make use of sources of energy from the sea.
B. To show that a steamship is better than other kinds of ships.
C. To argue that man should use steamships.
D. To indicate that it is warmer in the ocean than on land.4. According to the author, technology is important because ______.A. resources on land are running short in ten years
B. man can use it to explore the deeper sea
C. it is a lot of fun diving into the sea
D. ancient people used it to explore the sea5. According to the author, when will the problems to explore the deeper sea largely be solved?A. In the next generation.              
B. At the end of the 20th century.
C. In the near future.                  
D. By the middle of the 21st century.

阅读理解。    Among the most popular books being written today are those which are usually classified as science
fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore,
some of the most successful films in recent years have been based on science fiction stories. 
    It is often thought that science fiction is a fairly new development in literature, but it can be found in
books written hundreds of years ago. These books were often concerned with the presentation of some
form of ideal society, a theme which is still often found in modern stories.
    Most of the classics of science fiction, however, have been written within the last one hundred years.
Books by writers such as Jules Verne and H. Wells, to mention just two well-known authors, have been
translated into many languages. Modern science fiction writers don"t write about men from Mars or space
adventure stories. They are more interested in predicting the results of technical developments on society
and the human mind or in imagining future world which results the world we live in now. Because of this
their writing has obvious political undertones. 
    In an age where science fact frequently overtakes science fiction, the writers may find it difficult to keep ahead of scientific advances.Those who see the future clearly can teach us how to master new technology
and live in a rapidly changing world. 1. You can find science fiction ______. A. only in modern literature
B. only in books written for children
C. in books written today and hundreds of years ago
D. as a new development in literature 2. Modern science fiction writers are interested in ______. A. writing about men from Mars
B. writing about everything but politics
C. imagining future world with the results of technical developments
D. writing space adventure stories 3. It can be concluded that modern science fiction____________.A. reflects social political reform
B. shows the writer"s viewpoints
C. is not as good as that in the past
D. is better than other literary forms4. Science fiction writers may provide a valuable lesson on how to deal with the problems of ______. A. conflict used by different political theories
B. adopting new technology and adapting quickly to its effect on society
C. conflict caused by different religious beliefs
D. space adventure5. Which of the following statements is NOT true?A. Science fiction often overtakes science fact.
B. Writers may find it hard to keep ahead of scientific advances.
C. Some of the most successful films of recent years have been based on science fiction stories.
D. Those writers who can see clearly the way we are going will give us valuable instructions.

阅读理解。     Since the 1970s, scientists have been searching for ways to link the brain with computers.
Brain-computer interface (界面) (BCI) technology could help people with disabilities send
commands to machines.
     Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic school
in Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person"s
thoughts.
     In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right
hand. He could even talk as he watched the vehicle and guided it with his thoughts.
     "Our brain has billions of nerve cells. These send signals through the spinal cord(脊髓)to the
muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these
weak electrical signals from reaching the muscles," Tavella says.  "Our system allows disabled people
to communicate with external world and also to control devices."
     The researchers designed a special cap for the user. This head cover picks up the signals from the
scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the
motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They
help the computer react to commands from the brain.
     Prof. Milan, the team leader, says scientists keep improving the computer software that interprets
brain signals and turns them into simple commands. "The practical possibilities that BCI technology
offers to disabled people can be grouped in two categories: communication, and controlling devices.
One example is this wheelchair."
     He says his team has set two goals. One is testing with real patients, so as to prove that this is a
technology they can benefit from. And the other is to guarantee that they can use the technology over
long periods of time.

1. BCI is a technology that can _________________.

A. help to update computer systems        
B. link the human brain with computers
C. help the disabled to recover                
D. control a person"s thoughts

2. How did Tavella operate the wheelchair in the laboratory?

A. By controlling his muscles.                
B. By talking to the machine.
C. By moving his hand.                        
D. By using his mind.

3. Which of the following shows the path of the signals described in Paragraph 5?

A. scalp→computer→cap→wheelchair
B. computer→cap→scalp→wheelchair
C. scalp→cap→computer→wheelchair
D. cap→computer→scalp→wheelchair 

4. The team will test with real patients to                         .

A. make profits from them          
B. prove the technology useful to them
C. make them live longer            
D. learn about their physical condition      5. Which of the following would be the best title for the text?A. Switzerland, the BCI Research Center
B. New Findings About How the Human Brain Works
C. BCI Could Mean More Freedom for the Disabled
D. Robotic Vehicles Could Help to Cure Brain Injuries
