Why does the electric car seem to be the best alternative so far？

A．It is comfortable.

B．It is best made.

C．It causes no pollution.

D．It makes less noise.

Researchers have learned that the slapping noise pigeons make when they suddenly take off is the sound of super charged lift. They call it the "clap fling" effect.

Here at SRI International scientists try to duplicate the pigeons' thrust. A flashing strobe reveals the secret.

Scott Stanford, a scientist at SRI, says, You re looking at the clap fling effect, where the two wings will come together and peel apart 【C2】______ each other, thus augmenting lift 【C3】______ drawing air from the top to the bottom. "

This mechanical bug won't get off the ground. 【C4】______ its flapping wings demonstrate a potential propulsion system for robotic birds: man-made rubbery muscle.

Roy Kornbluh works at SRI. "There, I'm turning the voltage on and off, and you can see when the voltage is on, the material is larger 【C5】______ when the voltage is off."

Super computers show high-speed airflows over supersonic aircraft.

But scientists have only begun to see how air flows 【C6】______ really low speeds.

Professor Max Platzer of the Naval Postgraduate School, says, "The flapping wing is generating a thrust, this way, this is the basic physics of the phenomenon."

It's pelicans--not pigeons--the Navy is looking at. The Navy is looking at the smooth easy flight of pelicans low over water--called "ground effect." Researchers at the Naval Postgraduate School are trying to imitate the pelican's efficiency.

Assistant Professor Kevin Jones of the Naval Postgraduate School says, " 【C7】______ flapping the wings, symmetrically, we're 【C8】______ effect imitating ground effect. We now have the same feature a bird sees when it's flying, over a ground plane."

An electric motor drives the flapping wings. Researchers here are working 【C9】______ ways to beam power to the tiny bird.

David Jenn of the Naval Postgraduate School says, "There's no battery inside of here, so we're going to set this inside the radar beam, and the energy is extracted from the radar beam and will be used to propel the motor."

Scientists are learning it's one thing to build an airplane, 【C10】______ quite another to build a bird.

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.

Lost Sea. It is listed by the Guinness Bool of World Records as the world&39;s largest underground lake. The Lost Sea is part of an extensive and historic cave system called Craighead Caverns.

The caverns have been known and used since the days of the Cherokee Indian Nation. The cave expands into a series of huge rooms from a small opening on the side of the mountain. Approximately one mile from the entrance, in room called "the Council Room", many Indian artifacts have been found. Some of the items discovered include pottery, arrowheads, weapons, and jewelry.

For many years there were persistent rumors of a large underground lake somewhere in a cave, but it was not discovered until 1905. In that year, a thirteen-year-old boy named Ben Sands crawled through a small opening three hundred feet underground. He found himself in a large cave half filled with water.

Today tourists visit the Lost Sea and ride far out onto it in glass-bottomed boats powered by electric motors. More than thirteen acres of water have been mapped out so far and still no end to the lake has been found. Even though teams of divers have tried to explore the Lost Sea, .the full extent of it is still unknown.

1、The Lost Sea is unique because it is__________.

A.part of a historical cave system

B.the biggest underground lake in, the world

C.listed in the Gninness Book of World Records

D.the largest body of water in Tennessee

Who located the Lost Sea in recent times？A.The Cherokee Indians.

B.Tourism.

C.Ben Sands.

D.Scientists.

It can be inferred from the passage that the Craighead Caverns presendy serve as__________. A.an Indian meeting ground

B.a tourist attraction

C.a motor boat race course

D.an underground testing site

The Craighead Caverns have been known__________.A.through history

B.since the time of the Indian Nations

C.since 1905

D.since divers explored them
