听力原文： The U.S. Navy on Wednesday admitted an Egyptian was killed this week when shots were fired from a military-contracted cargo ship at a boat near the Suez Canal. The United States originally said no one died in Monday’s encounter between the cargo vessel Global Patriot and three small boats near the Suez Canal. When the boas approached the Global Patriot, a native Arabic speaker using a bullhorn warned the vessels to turn away, the U.S. Embassy in Cairo, Egypt, said. "A warning flare was then fired," the embassy said in a statement. "One small boat continued to approach the ship and received two sets of warning shots." The embassy said Wednesday it appears that one of the warning shots killed an Egyptian on the approaching boat. The embassy did not mention anyone being wounded. Egyptian media reports said two people were wounded in addition to the death. A senior U.S. military official said an armed military security team was on board for the canal transit. An Egyptian security official, speaking to the AP on condition of anonymity, said the merchants know not to approach military vessels, but the fact that the Global Patriot was a civilian vessel might have led to confusion.
What might happen in the accident on Monday？
听力原文：Hunger is not caused by a global scarcity of food．The world can easily produce enough to feed everyone，without any government support．When people go hungry，it is because they do not have access to food—sometimes for reasons of War or politics，most often because of poverty．
The speaker believes that a practical solution to the problem of starvation is to remove obstacles to adequate supply of food rather than to increase production of it.
Charles Andrews thinks that the best training involves ______.
Activities in environments that pose great danger to humans, such as locating sunken ships, cleanup of nuclear waste, prospecting for underwater mineral deposits, and active volcano exploration, are ideally suited to robots. Similarly, robots can explore distant planets. NASA's Galileo, an unpiloted space probe, traveled to Jupiter in 1996 and performed tasks such as determining the chemical content of the Jovian atmosphere.
Robots are being used to assist surgeons in installing artificial hips, and very high-precision robots can assist surgeons with delicate operations on the human eye. Research in telesurgery uses robots, under the remote control of expert surgeons that may one day perform. operations in distant battlefields.
Robotic manipulators create manufactured products that are of higher quality and lower cost. But robots can cause the loss of unskilled jobs, particularly on assembly lines in factories. New jobs are created in software and sensor development, in robot installation and maintenance, and in the conversion of old factories and the design of new ones. These new jobs, however, require higher levels of skill and training. Technologi cally oriented societies must face the task of retraining workers who lose jobs to automation, providing them with new skills so that they can be employable in the industries of the 21st century.
Automated machines will increasingly assist humans in the manufacture of new products, the maintenance of the world' s infrastructure, and the care of homes and businesses. Robots will be able to make new highways, construct steel frameworks of buildings, clean underground pipelines, and mow lawns. Prototypes of systems to perform. all of these tasks already exist.
One important trend is the development of micro-electromechanicai systems, ranging in size from centimeters to millimeters. These tiny robots may be used to move through blood vessels to deliver medicine or clean arterial blockages. They also may work inside large machines to diagnose impending mechanical problems.
