听力原文： Are electric cars the way of the future？ Automobile manufactures are under pressure to develop ca rs that do not pollute. One powerful motive is a California law requiring that by the year 2000 ten percent of new car sells in the state be so called zero-emission vehicles. These cars must put no pollutants whatsoever into the atmosphere.

California is a huge market for the automobile companies, so they are working hard to meet these standards. So far the electric car seems to be the best alternative. So the big advantage of electric cars is that they don't pollute. However they will be in competition with gas-powered cars and that's where the weaknesses come out.

The big problem is that the batteries that power electric cars weigh a lot relative to the amount of power they deliver. For instance, in one prototype electric car, the batteries weighed 400 kilograms. And they provide enough energy to go 250 kilometers before recharging, which takes eight hours. Compare that to a moderately fuel-efficient conventional car, it can go 600 to 700 kilometers on a tank of gas and refilling takes just minutes. If there are other drains on an electric car's batteries besides the motor, headlights, air conditioning or a heater, its already limited range will be significantly reduced. So automobile engineers are trying to make more powerful batteries that would increase the cars' range and make them more attractive to buyers.

What is the talk' mainly about？

A．Automobile safety.

B．Increasing fuel efficiency.

C．California's pollution laws.

D．Electric-powered cars.

听力原文： I'm sure almost every one of you looked at your watch or at a clock before you came to class today. Watches and clocks seem as much a part of our life as breathing or eating. And yet did you know that watches and clocks were scarce in the United States until the 1850s. In the late 1700s, people didn't know the exact time unless they were near a clock. Those delightful clocks in the squares of European towns were built for the public. After all, most citizens simply couldn't afford a personal time piece. Well into the 1800s in Europe and the United States, the main purpose of a watch, which by the way was worn off the wrist and on a gold chain, was to show others how wealthy you were. The word "wrist watch" didn't even enter the English language until nearly 1900. By then the rapid pace of the industrialization in the United States meant that measuring time had become essential. How could the factory worker get to work on time unless he or she knew exactly what time it was？ Since the efficiency was now measured by how fast the job was done, everyone was interested in time. And since industrialization made possible the manufacture of large quantities of goods, watches became fairly inexpensive. Furthermore electric lights kept factories going around the clock. Being "on time" had entered the language and life of every citizen.

(29)

A．The industrialization of the United States.

B．The development of individual timepieces.

C．Reasons for increased productivity.

D．How wristwatches are manufactured.
