But the last-minutecalls made by some of the passengers give us a more complete account of thestruggle of these everyday people. Here is one of the stories of courage and heroism.STEP 2 — Warming-up (20 minutes)1.DiscussionTeacher: Before we study the text, let me ask you some questions.1) What do you know about the events that took place in America on September11, 2001?2) Why do you think the terrorists attacked those targets?3) What can be done to stop such events happening again?*Summarize the answers to these questions.2.Questions about the TextBased on the title: Flight 93: What I Never Know, just guess the author‘s ideatowards Terrorism.4) Why does the author say that she will never really make sense of September11?5.) What‘s your idea of September 11?Information Related to the Text1) TerrorismTerrorism is the use of violence, or the threat of violence, to create a climateof fear in a given population. Terrorist violence targets ethnic or religious groups,governments, political parties, corporations, and media enterprises. Organizationsthat engage in acts of terror are usually small in size and fear generated by theirviolence, which seek to magnify their influence and power to affect politicalchange on either a local or an international scale.2) New JerseyA state of the east-central United States on the Atlantic Ocean. It was admittedas one of the original Thirteen Colonies in 1787. Trenton is the capital andNewark the largest city.3) NewarkA city of northeast New Jersey on Newark Bay, an inlet of the Atlantic Ocean,opposite Jersey City and west of New York City. It was settled by Puritans in 1666 and is today a heavily industrialized port of entry.4) CaliforniaA state of the western United States on the Pacific Ocean. California is often called the Golden State because of its sunny climate and the discovery of gold during its pioneering days. Sacramento is the capital and Los Angelas the largest city.5) WindhamA town located in Greene County, New York, USA. The town had a total population of 1,660 at the 2000 census. The town is believed to be named after a location in Connecticut.6) New YorkA state of the northeast United States. It was admitted as one of the original Thirteen Colonies in 1788. Albany is the capital and New York City the largest city. New York City is also the financial center of the nation.7) San FranciscoA city of western California on a peninsula between the Pacific Ocean and San Francisco Bay, an inlet of the Pacific. Discovery of gold nearby in 1848 changed the city from a small community into a thriving boom town known for its lawlessness and bawdy amusements.8) The World Trade CenterFormer building complex in lower Manhattan, New York City, consisting of seven buildings and a shopping concourse on a 16-acre (6.5-hectare) site; it was destroyed by a terrorist attack in Sept., 2001. Prior to its destruction, the World Trade Center had been the world‘s largest commercial complex, home to many businesses, government agencies, and international trade organizations.9) The PentagonThe Pentagon is the headquarters of the United States Department of Defense. Those who work within its walls often simply call it the Building. As a symbol of the US military, "the Pentagon" is often used metonymically to refer to the Department of Defense rather than the building itself. On September 11, 2001, exactly sixty years after construction began on the complex, part of the building was destroyed in the terrorist attacks which also brought down the World Trade Center‘s Tw in Towers.10) Remarks by the President Less than One Hour after the AttackI want to reassure the American people that the full resources of the federal government are working to assist local authorities to save lives and to help the victims of these attacks. Make no mistake: The United States will hunt down and punish those responsible for these cowardly acts.I‘ve been in regular contact with the Vice President, the Secretary of Defense, the national security team and my Cabinet. We have taken all appropriate security precautions to protect the American people. Our military at home and around the world is on high alert status, and we have taken the necessary security precautionsto continue the functions of your government.We have been in touch with the leaders of Congress and with world leaders to assure them that we will do whatever is necessary to protect America and Americans.I ask the American people to join me in saying a thanks for all the folks who have been fighting hard to rescue our fellow citizens and to join me in saying a prayer for the victims and their families.The resolve of our great nation is being tested. But make no mistake: We will show the world that we will pass this test. God bless.11) What had happened about Flight 93 on September 9, 2001?8:42 a.m. United Airlines Flight 93 takes off from Newark, NewJersey, with 44 aboard. The flight is bound for San Francisco. 9:16 a.m. The FAA informs NORAD that Flight 93 may have beenhijacked.9:24 a.m. NORAD orders two F-16s at Langley Air Force Base inVirginia to intercept United Airlines Flight 77.9:30 a.m. The two F-16s from Langley Air Force Base are airborne.After Flight 77 hits the Pentagon, the jets are ordered to perform coair patrols over Washington.

China's telecommunications industry has seen revolutionary transformation and growth over the past three decades. Chinese Internet users number nearly 150 million, and the PRC expects to quickly pass the US in total numbers of connected citizens. The number of mobile and fixed-line telephone users soared from a mere 2 million in 1980 to a total of nearly 800 million in 2007. China has been the most successful developing nation in history for spreading telecommunications access at an unparalleled rapid pace.The Telecommunications Revolution 背景知识(background info) •The Telecommunications Revolution1. telecommunications: Telecommunications, from Greek, means “communi cations at a distance”. Telecommunications through voice, data, and image communication is changing the world. The ease of accessing information and people anywhere at anytime is having major impacts on society, business, and finance. Two major trends have occurred in the technology that is applicable to telecommunications. The first trend has been the incredible increase in the processing power of digital computers, namely, dramatic decreases in physical size along with equally dramatic increases in complexity, speed, and capacity. The second trend has been the explosive growth in transmission capacity through the widespread use of optical fiber across continents and under oceans. These two trends have had impressive long-term consequences for telecommunications around the world. The Internet and the World Wide Web have already created a global system for the access of information. It has become popular that people check flight, weather, and hotels before traveling to a foreign country. E-mail makes it easy to keep in contact instantly with colleagues and friends around the globe. But many of the peoples of the world do not even have a telephone, much less access to the Internet and the information. The challenge to the telecommunications industry is to bridge the digital gap and extend the availability of telecommunications to all parts of the planet. For an introduction to the fundamentals of telecommunications, please check out the websites at /manual/one.html and /online/tutorials/fund_telecom/. Anothereasy-to-understand telecommunications primer can be found at/500/primer.html.2. optical fiber: Optical fiber (or “fiber optic”) often refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic wire or fiber. Optical fiber carries much more information than conventional copper wire and is in general not subject to electromagnetic interference and the need to retransmit signals. Most telephone companylong-distance lines are now of optical fiber. Transmission on optical fiber wire requires repeater at distance intervals. The glass fiber requires more protection within an outer cable than copper. For these reasons and because the installation ofany new wiring is labor-intensive, few communities yet have optical fiber wires or cables from the phone company's branch office to local customers (known as local loop). Single mode fiber is used for longer distances; multimode fiber is used for shorter distances. Please visit/fiber-optic-tutorial-basics.asp and/fibercable.htm for more information on optical fiber.3. information age: When we say that we live in the information age, we mean that we live in a time when information is very important and easy to get. The information age is an era of fundamental and global change in intellectual, philosophical, cultural and social terms. Today's information age began with the telegraph. It was the first instrument to transform information into electrical form and transmit it reliably over long distances. New techniques of encoding and distributing digital information are pacing the spread of the information age throughout society. For a historical perspective on the information technology, check out the websites at/resource/faq/nmah/techhistory.htm and/infoage/infoage.html. The web page at/crsweb/infolit/andyou/mod9/infotech.ht m provides extensive links to issues related to the information age. For a discussion of China in the information age, check out the paper at/~pam/papers/chinaip.html.4. information superhighway: A name first used by (former) U.S. Vice President Al Gore for the vision of a global, high-speed communications network that will carry voice, data, video, and other forms of information all over the world, and that will make it possible for people to send email, get up-to-the-minute news, and access business, government and educational information. The Internet is already providing many of these features, via telephone networks, cable TV services, online service providers, and satellites. In the U.S., the information superhighway is also known as National Information Infrastructure(/fs-1037/dir-024/_3476.htm). The information superhighway can be understood to be a highway which has computer technology and modern communication technology serving as the base of the road and fiber-optic cables serving as the surface of the road. The “vehicles” are the multimedia machines equipped with computer, television and telephone, and high speed transmission and exchange of various multimedia information forms the web covering the whole nation. If the national superhighways all over the world are linked together, the global information superhighway will be created.Who first created the idea of “constructing” a superhighway?In 1955, Albert Gore, then Tennessee Democratic senator, put forward in the U.S.Congress the act of interstate superhighway, which was later proved to have greatly promoted the American economic development. In 1991, his son, Al Gore, proposed another act — high performance computing act, HPCA(/congressional/laws/pl_102-194.html). For the first time, HPCA demanded high performance computer and communication. The core of the act is to set up a national research and education network, NREN.For more information on the subject, check out the websites at/gallery/abrahams/ish.htm,/IT/infohghy.cfm and.au/http/sfist/shwy0.htm.5. BellSouth Corporation: BellSouth is a telecommunications company in the U.S. that mainly serves the southern states. Its business ranges from voice (such as local and long-distance telephone and wireless) to data (computer networks) services.
