message. Though for many years science has cautioned against hearing too much of what we humans
would like to hear when we are trying to understand animal sounds, the musicality in some sounds is now
starting to have an effect on the science of animal communication itself.
Many specific animal sounds express aggression(进攻), warning, or food, but such practical
explanations are tough to apply to the long songs. Some whale songs can go on for up to 24 hours. The
usual explanation for birdsong is that the birds are singing to attract mates or to announce the limits of their area. But the audience is not always evident for these long love songs, which have many of the elements
related to human music: rhythm, melody (旋律), themes, repeating patterns
, organization, variety, interest - all adding up to something humans have found beautiful for thousands of years. "Birds taught man," wrote Roman poet and philosopher (哲学家) Lucretius, "and taught them songs before their art began." What is the scientific value of such sounds? The advantage of hearing music in nature and trying to
reach out to nature through music is that though we don"t fully understand it, it is so accessible.
Music refuses explanation, but it clearly expresses something deep and important, which humans can"t
live without. Finding music in the sound of birds, whales and other animals makes the farther frontiers
(边缘) of nature see much closer to us.
B. fought against
C. been filled with
D. been satisfied with
B. It is believed that birds are singing to attract mates or to warn the limits of their areas.
C. The songs of a bird really carry an emotional message such as "aggression and caring".
D. It is not very long for people to know that birdsong does ha
ve something beautiful. B. Birds can teach people how to go on singing a song up to 24 hours.
C. Human music has, in fact, come from the sounds of birds in nature.
D. Humans learned something beautiful from the sounds of many animals
B. is very easy to pick up and listen to

Bart: I don"t know that present-day electronic chips are, but some sort of chips - I"d guess maybe
plastic. Our three-pound brain is definitely a wonder, perhaps the greatest wonder of natural biology. In
this coming century,
we"ll be re-engineering the brain a piece at a time, first with implants (植入物) and finally engineering an complete replacement. There"s no question that in the distant future we"ll play the
music of the mind on instruments different from the current ones. So, yes, chips are our destiny (命运).
Edward: In 3000 perhaps the biggest difference from today is that there will be no more men. Females can have female children, without any need for men. In about ten years, we"ll find the cocktail that women can take to have female children. There"ll be no need for men at all.
Greg: What is Heaven? Heaven"s a place where you can create worlds at will, and the ideal Heaven is where you run the whole thing yourself. The current means of getting to Heaven involve various
supernatural systems for which, at this point, there"s no scientific evidence. So I think we can reduce
Heaven to an engineering project which we"re doing. The demand for Heaven is great-witness the desire of every human heart, from the people who built the ancient pyramids to modern society, to live beyond one"s given time. Our plan is to change human consciousness from the brain to bits of information in a computer
chip, or some other kind of computational medium, so that just by thinking we"ll be able to create our own personal world. And I think the first stage of Heaven will be the feeling world, and beyond that I think we"d find a higher, more spiritual plane.
B. it may be driven by plastic chips
C. it may be replaced by robots
D. it may play the music of the mind
B. Chips are on the way to controlling mind.
C. Chips are the production of future technology.

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
tourism development and management at our five action sites, we assisted with regional marketing efforts
to promote eco-tourism opportunities.
B. sixth
C. fifteenth
D. eighth
B. The Nature Conservancy cooperated agencies in the Yunnan Great Rivers Project.

C. government agencies
D. tourism enterprises
B. Tourism is extremely helpful to people in Yunnan.
C. Tourism does no good to our environment.
D. Tourism is an opportunity for the economy as well as threat to the environment.
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.
B. how to build your own website
C. how to meet people online
D. what a website is made up of
B. where you can buy what you want
C. where you can get free services
D. where you can meet people on the Internet
l the contents of your websiteB. 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 magazine
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
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.
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.
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.
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.
B. Black Hole Information Paradox
C. Black Hole Mystery
D. The Cause of the Black Hole
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.
B. Sea Harvest and Food
C. Sea and Sources of Energy
D. Sea Exploring Technology.
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 floor
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.
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 sea
B. At the end of the 20th century.
C. In the near future.
D. By the middle of the 21st century.
