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. 【C1】______

The journey to the moon has been the first step towards future explorations in space. The distance between the moon and the Earth is very short indeed when compared with the distances between Earth and the other planets. Mars, the nearest planet to Earth is of miles away ! Traveling to the planets or travels between planets will be man’ s next aim. Such travels will be more difficult than the trip to the moon and certainly more exciting. Recently, two American unmanned spacecraft, Vikings 1 and 2, landed on Mars in an attempt to discover whether that planet had any life on it. So far the presence of life on Mars has neither been proved nor ruled out. Russian space-probes have discovered that the surface of Venus is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely, dense and the pressure is nearly a hundred times greater than the pressure of the Earth’s atmosphere. Scientists believe that in the future, space stations can be built in space. These stations can act as stop-over points in space. Spacecraft can refuel at these stations and get their supply of air, food and water. Spaceships of the future will be bigger and faster. They will be able to carry passengers for trips to the moon or planets. Man may in the future find planets which have the same conditions as those we have on Earth, and make them his home. However such a possibility is still in the distant future. At the same time, Man should realize that the Earth will be his only home for a long time and begin to value and care for it. Which of the following statements is true？ A．Recently, two American astronauts have landed on Mars. B．The surface of Mars is very hot. C．The journey to the moon started the future exploration in space. D．There is life in Venus.

What have India and Pakistan agreed to do？ A．To improve telecommunications. B．To avoid misunderstanding. C．To warn of military clashes. D．To prevent nuclear confrontation.

Japan has a population of over 116,000,000. The people are thickly settled on the four main islands. Since only one sixth of the land is arable, Japan relies on imported food. To pay for the imports, Japan exports manufactured goods. Japan builds and sells cars, motorcycles, television sets, radios and cameras. Textiles and chemicals also made. In Yokohama Harbor, ships are constructed for use by other nations. The "head start" western nations had may be the reason for Japan's success today. Western countries are still using machines and technology that they developed many years ago. Japan is using newer, improved methods. For example, robots are relieving factory-workers of long, tiring jobs. Modem technology has brought modern problems. Air and water quality reached dangerous levels in some parts of Japan in the late 1960's. Since then, the Japanese government has applied strong pollution controls. The main idea of the passage is that Japan ________. A．surprises the world. B．Suffers from serious air and water pollution C．Leads in exporting goods D．Leads in technology in the world today

A．distortion B．diversion C．dissipate D．discount

As the 100th anniversary of the first powered flight approaches in December, the industry it launched is still remarkably primitive. The car industry, created not long after the Wright Brothers made history, is now a global industry dominated by a dozen firms, at least half of which make good profits. Yet commercial aviation consists of 267 international carriers and another 500-plus domestic ones. The world's biggest carrier, American Airlines, has barely 7% of the global market, whereas the world's biggest carmaker, General Motors, has (with its associated firms) about a quarter of the world's automobile market. Aviation has been incompletely deregulated, and in only two markets: America and Europe. Everywhere else deals between governments direction who flies under what roles. These aim to preserve state-owned national flag-carriers, run for prestige rather than profit. And numerous restrictions on foreign ownership make cross-border airline mergers impossible. In America, the big network carriers face barriers to exit, which have kept their route networks too large. Trade unions resisting job cuts and Congressmen opposing route closures in their territory conspire to block change. In Europe, liberalization is limited by bilateral deals that prevent, for instance, British Airways (BA) flying to America from Frankfurt or Pads, or Lufthansa offering transatlantic flights from London's Heathrow. To use the car industry analogy, it is as if only Renaults were allowed to drive on French motorways. In airlines, the optimists are those who think that things are now so bad that the industry has no option but to evolve. Frederick Reid, president of Delta Airlines, said earlier this year that events since the 911 attacks are the equivalent of a meteor strike, changing the climate, creating a sort of nuclear winter and leading to a "compressed evolutionary cycle". So how, looking on the bright side, might the industry look after five years of accelerated development？ According to the author, the deeper problems of aviation industry ______. A．are the effects of various disasters B．are actually not fully recognized C．are attracting a lot of attention D．are not the real cause of airlines' bankruptcy
