第2单元2013年大学网络学习新闻英语二，网上虽然有些答案但是不大一样，也没有听力原文，这里的最全准备1.Exercise 1: Listen to this passage and decide whether the following statements are true or false, write T for true and F for false.听力文本：Airport Security Screens Passengers Using New TechnologyChecking baggage for explosives hasn't been a problem. Airportsecurity can put bags in x-ray machines, open them up to lookinside, or use advanced machinery that that check traces ofchemicals often used in explosives.But checking people's bodies isn't so easy. A TSA initiativethat began last September to rigorously frisk more people led todozens of sexual harassment complaints. So the TSA turned totechnology installing what looks like a longer, more complexwalk-through metal detectors in nine airports around the country.Jose Ralls is the TSA director from McCarran International inLas Vegas.Jose Ralls: The machine actually will talk to the individual,telling them to stand inside and wait, and as soon as they arecleared, it will tell them to proceed.From a distance, Mr. Ralls watches one airport passenger gothrough the process.Jose Ralls: Now he knows to go on through, and he just waits,and as soon as the air is analyzed he will be allowed to proceedforward.The machine blasts air downward and across whoever inside theportal. Mr. Ralls says that often startles people.Jose Ralls: That's why our focus out there is to explain tothem what will be taking place,the noise that they will be hearing.The way it's supposed to work is that suspicious particles onclothing and exposed skin are blasted towards the floor -- where,within seven seconds, the machine can detect 40 types of explosives. If any are found, security is alerted.According to the manufacturer, Smith Detection, the portalsalso have less than 1% error rate. Company vice president MarkLastra says this technology is commonly used elsewhere. Smith Detection: Mostly highly controlled facilities, sensitive security, such as nuclear power plants and governmentbuildings with high security needs.Along with increasing security, the TSA hopes to cut down onpassenger wait times. It is collecting data from the airports inthis test base to see if the machines are faster and more efficient than human inspectors.The Transportation Security Administration plans to deployfive more of these portals elsewhere in the nation by late spring.Eventually it would like the explosive detectors to be as commonas metal detectors.I am Ky Plaskon in Las Vegas.题目：1.For a long time, checking baggage forexplosives has been aproblem for airport security.文本：你的答案:F正确答案:F得分:5.00题目：2.Within seven seconds, the machine mentioned in the news candetect 14 types of explosives.文本：你的答案:F正确答案:F得分:5.00题目：3.According to the manufacturer, theportals also have no errorrate.文本：你的答案:F正确答案:F得分:5.00题目：4.Along with increasing security, the TSA hopes to cut down onpassenger wait times.

He says that in the future, this computer model may be able to predict some earthquakes just as hurricane paths are nowforecast.John Rundle: Our goal is to be able to make forecasts on that kind of time scale and then to improve it to the point where we're actually able to see the preparation process in the months andyear or two leading up to a large earthquake.Dr. Rundle says that several decades from now, one third of the world's population could live in seismically active regions. He hopes that by then, the virtual reality software will helpprevent the heavy loss of life caused by tragedies such as theSouth Asia earthquake.Leta Hong Fincher, VOA news.题目：1.Geologists say they knew a large earthquake was coming in South Asia, and they also know when.文本：你的答案:F正确答案:F得分:4.00题目：2.The Himalayan Mountains were formed after a landmass broke off from Antarctica, drifted north and collided with the rest of Asia.文本：你的答案:T正确答案:T得分:4.00题目：3.Scientists say the Nouth Asian land mass is still movingtowards Sorth Asia at the rate of about two meters a year, making the area prone to earthquakes.文本：你的答案:F正确答案:F得分:4.00题目：4.Another earthquake-prone region is along the 1300 kilometer San Andreas Fault in America.文本：你的答案:T正确答案:T得分:4.00题目：5.Dr. Rundle says that several decades from now, one third of the world's population could live in seismically active regions.文本：你的答案:T正确答案:T得分:4.002.Exercise 1 Part 2: Listen to the passage and answer eachquestion by giving the best choice.Computer Simulations Might Predict Future EarthquakesGeologists say they knew a larger earthquake was coming inSouth Asia, but they did not know when.The Himalayan Mountains were formed some 150 million years ago after the landmass that is now India broke off from Antarctica, drifted north and collided with the rest of Asia.Scientists say the South Asian land mass is still movingtowards North Asia at the rate of about two centimeters a year, making the area prone to earthquakes.Harley Benz is a researcher at the U.S. Geological Surveyearthquake information center.Harley Benz: It's a broad zone of deformation, and across this zone that extends 1,000 kilometers, you have a whole series offaults and folds.Another earthquake-prone region is along the 1300 kilometer San Andreas Fault in California.It is here that John Rundle, a physics and engineeringprofessor at the University of California at Davis, is testing his earthquake computer simulation.John Rundle: You take these simulations, you turn them on, you run them and you do as good a job as possible in simulating orrepresenting the past history of activity on the fault systems.Dr. Rundle uses information from tools such as globalpositioning satellites to create a virtual reality model ofthousands of years of earthquake activity along the San Andreas Fault.

Indonesia, which was badly hit by the Indian Ocean tsunami four years ago, is expected to have its own early warning mechanism working by the end of the year.The Australian project is based in the southern city ofMelbourne and relies on high technology deep sea buoys. Five are in waters northwest of Australia, while others are off thecontinent's east coast in the Coral Sea. Additional buoys arefurther south in the Tasman Sea.Barry Drummond from the government's Geosciences office says the new system will provide accurate information about the risks of giant waves."Rather than saying a tsunami is on its way and it may impact the coastline of whichever state, the center is now in a position to be able to say, along that coastline these areas are moresusceptible than those and in these areas the threat will be to things in the water; swimmers, boats, harbors and that sort ofthings and within these other areas the tsunami may come ashore and then these are the areas that you have to worry about,"explained Drummond. "So far more detail. It allows us not toover-warn and ensures we don't under-warn."The sensitive monitoring equipment allows scientists topinpoint the location of an earthquake that could trigger atsunami, its depth and strength.The Australian system also will provide sea level and seismic data to vulnerable island nations in the Pacific Ocean and also to authorities in Japan.The epicenter of the undersea earthquake that triggered the December 26, 2004, Indian Ocean tsunami occurred off the westcoast of Sumatra in Indonesia.More than 200,000 people were killed in 11 countries. Manycoastal areas were swamped by waves up to 30 meters high.It was one of the world's worst natural disasters. Indonesia, Thailand, India and Sri Lanka were hardest hit.Unlike the Pacific, the Indian Ocean did not have a system to warn coastal communities that a tsunami was on the way.In the aftermath of the 2004 disaster, scientists andgovernments began working on an alert network for the Indian Ocean region.题目：1.Which one could be the possible title for the news?文本：A) The Australian Tsunami Warning CenterB) Australia Sets Up New Tsunami Warning SystemC) Indian Ocean TsunamD) Tsunami's Impact on Scientific Research你的答案:D正确答案:D得分:3.00题目：2.Due to Indian Ocean tsunami, how many people were killed?文本：A) more than 120,000 peopleB) more than 20,000 peopleC) more than 200,000 peopleD) more than 200,000,000 people你的答案:C正确答案:C得分:4.00题目：3.Which countries were not hardest hit during Indian Oceantsunami?文本：A) IndonesiaB) ThailandC) IndiaD) Singapore你的答案:D正确答案:D得分:3.002.Passage One Exercise 1 Part 2: Listen to the passage and decide whether the following statements are true or false, write T for true and F for false.Australia Sets Up New Tsunami Warning SystemThe Australian tsunami warning system is part of whatofficials hope will be a network of centers across the IndianOcean that share scientific data.
