第6题

A pilot cannot fly a plane by sight alone. In many conditions, such as flying at night and

landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300, 000 kilometers in one second. A radar set sends out a short burst of radio waves: Then it receives the echoes produced when the waves bounce off objects. By determining the time it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word "radar," in fact, gets its name from the term "radio detection and ranging." "Ranging" is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots, radar is essential for air traffic control, tracking ships at sea, and for tracking weather systems and storms.

What is the main topic of this passage?

A．The nature of radar.

B．Types of ranging.

C．Alternatives to radars.

D．History of radar.

听力原文:Japanese electronics maker Toshiba said Monday that it was buying nuclear plant b

听力原文：Japanese electronics maker Toshiba said Monday that it was buying nuclear plant builder Westinghouse Electric, the US-based unit of the British government's British Nuclear Fuels, for US ＄5.4 billion.

Toshiba Chief Executive Atsutoshi Nishida said that while the price might seem quite high, Toshiba had a lot of competition for the company and that the future growth and profit potential of the business made it the correct price.

By 2020 the market for nuclear power generation is expected to grow 50 percent compared to 2005, Nishida said at a London news conference. "Toshiba is responding to this challenge by acquiring Westinghouse."

Upon completion of the acquisition, Toshiba expects its nuclear power business to expand to three times the current level by 2015 as a result of operational and technological synergies, Toshiba said in a statement.

Toshiba expects to close the deal within six months and is not expecting regulatory troubles, Nishida said.Westinghouse will keep its headquarters in Pennsylvania, as well as its equipment, employees and trademarks, he said.

Toshiba, which makes electronic goods including DVD players, semiconductors, electric motors and power systems, is preparing for an expected surge of new investment in power plants in China, India and the US.

Westinghouse, which has built most of the nuclear reactors in the United States, is likely to design the plant and service them when they come online.

What does the passage mainly discuss?

A．The acquisition of British Nuclear Fuels by Toshiba

B．The acquisition of Westinghouse Electric by Toshiba

C．Toshiba's expansion in nuclear power business.

D．Toshiba's embarking on nuclear power business.
