n．But there are two tests that are more important than all the others．In the first test，a modem airliner must fly at very high altitudes． Air must be pumped into the plane so that the passengers can breathe. The metal structure of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure on a small window, for example, is like a huge foot that is trying to get out. If a small part of the plane were to crack, the plane would explode in the sky.. In order to test the structure of the plane, it is lowered into a huge tank of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is in the air. Finally, there is an explosion. Engineers can discover which part of the plane has cracked. In the second test, the test pilot must find out exactly what happens when all the engines are shut off at once. He takes the plane up very high. Then he shuts the engines off. The plane begins to fall like a stone. It is the pilot's job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they can ever carry passengers.

Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.

听力原文： The helicopter can fly forwards, backwards, up, down, and sideways. It can also hover in the air. It needs no runway to operate from. It can land and take off from a flat roof-or a clearing in the jungle.

The main disadvantage of the helicopter is that it cannot fly as fast as most planes. It is also often noisy. Helicopters are widely used by the armed forces. They are also useful for sea and mountain rescue operations. In some cities they are used for regular passenger flights.

The helicopter is different from an aeroplane which gets its lift from fixed wings, and its thrust from a propeller or a jet. Instead of wings, the helicopter has a many-bladed rotor on its top. This is driven by the engine. The rotor blades are, however, the same shape as wings and they provide lift for the helicopter when they turn. The spinning rotor also propels the helicopter. The helicopter pilot maneuvers his craft by altering the angle of the rotor blades.

As the turning of the rotor tends to make the body of the helicopter turn as well, most helicopters have a small rotor on their tail.

Ultralight(超轻型的) airplanes are a recent development in aviation that provide what aviation enthusiasts have long been seeking: an inexpensive airplane that is easy to fly. The ultralight plane was born of the marriage of the hang glider and the go-kart(微型单座赛车) engine around 1974, when John Moody mounted a 12-horsepower go-kart engine on his Icarus Ⅱ hang glider.

Today’s ultralights are not just hang gliders with engines; they are" air recreation vehicles". Modem ultralight planes use snowmobile(雪地机动车)engines that let them cruise at about 50 miles per hour, climb at about 500 feet per minute, and carry combined payloads of pilot and fuel up to about 200 pounds, which is about equal to an ultralight plane’s weight when empty. More than ten thousand ultralight planes were sold last year at prices ranging from $ 2,800 to $ 7,000. But the main reason for the increasing popularity of these aircraft is not that they are inexpensive, but that they are fun to fly.

The modern ultralight plane would look very familiar to the earliest pioneers of aviation. Otto Lilienthal made more than 2000 flights in Germany in the 1890’s in what were actually hang gliders. Octave Chanute designed and built many early hang gliders. Augustus Herring, Chanute’s assistam, used these gliders as models for a glider that he built for him self. On this glider, Herring installed a compressed-air motor and flew 267 feet in 1898. The Wright brothers' Flyer was the grandfather of today’s ultralight plane. The pilot sat right out in the open, just as in modem ultralights, and used con trois that were much the same as those used in today's machines.

Though most ultralight planes are used for pleasure flying, some are also used for crop dusting, aerial photography, and even military observation service. The likelihood is that further uses will be found for ultralight planes, but their greatest use will continue to be as air recreational vehicles.

The author seems to feel that ultralight airplanes are ______.

A．a toy for the rich

B．nothing but hang gliders

C．a new development that meets the needs of aviation enthusiasts

D．the most important development in aviation since the Wright brothers' Flyer

f people involved in patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient—no matter where he or she may be.

Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis (telemedicine) will be based on real physiological data from the actual patient. A group from the University of Kentucky has shown that by using an off-the-shelf PDA(personal data assistance) such as a Palm Pilot plus a mobile phone, it is perfectly feasible to transmit a patient's vital signs over the telephone. With this kind of equipment in a first-aid kit, the cry asking whether there was a doctor in the house could well be a thing of the past.

Other medical technology groups are working on applying telemedicine to rural care. And at least one team wants to use telemedicine as a tool for disaster response—especially after earthquakes. Overall, the trend is towards providing global access to medical data and expertise.

But there is one problem. Bandwidth is the limiting factor for transmitting complex medical images around the world—CT scans being one of the biggest bandwidth consumers. Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes, wars or famines. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of distributed medical intelligence.

Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should usher in an era when telemedicine and the sharing of medical information, expert opinion and diagnosis are common.

The basis of remote diagnosis will be______.

A．standardized symptoms of a patient

B．personal data assistance

C．transmitted complex medical images

D．real physiological data from a patient

the various networks of people involved in patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient -- no matter where he or she may be.

Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis, that is telemedicine, will be based on real physiological data from the actual patient.

but in practice it means that people from black and ethnic groups get an unfair treatment be cause their particular problems are seldom acknowledged.

So a project was piloted involving Bangladeshi women in inner city London, most of whom migrated to the UK in the 1960s and 1970s from a rural background. Many of these, women turned to their doctors with common symptoms of anxiety, such as headaches, sleeping difficulties, loss of appetite and lack of energy. They were usually prescribed tranquillizers(镇定剂)or even Vitamin C. Since the underlying causes remained, the women visited their doctors with in creasing frequency and some were referred on to mental-health professionals.

The psychologists wanted to see how normal Western approaches to anxiety problems might work when applied across cultures. However, they found that many things in the standard approach had to be changed. They had to translate many of the usual examples -- they would normally compare learning to relax with learning to drive, for instance, which would not have been culturally appropriate. At first they asked the women to rate, on a scale one to ten, the effect of relaxation on their level of anxiety. They found numbers an odd way of expressing how they were feeling. So psychologists shifted their focus to words rand talked of five stages form. "very good" to "very bad".

As it was a pilot project, there were Shortcomings. Psychologists looked for too little back up and did not collect as much objective data as they might have done with a white group. They fell into the white stereotype of assuming that Bangladeshi women would find the use of various checklists and written records foreign. Perhaps racism has conditioned the professionals to a greater extent than they expected. Psychologists found that using a Western model across cultures has potential. But it needs political, financial and personal commitment.

What does the phrase "color blind" in Paragraph 1 mean？

A．Not liking people from ethnic groups.

B．Giving specialized treatment to ethnic groups.

C．Unable to distinguish certain colors.

D．Not treating ethnic groups differently.

Time changes quickly. Education is going rapidly out of fashion. "Learning" (to be exact, "lifelong learning" ) is New Labour's new buzzword (时髦语). The shift from "education" to "learning" reflects more than a change of language. It stems from both educational research and left-wing ideas. During the 1980s, British educationalists got some new American ideas. One was the notion that traditional examinations do not test the full range of people's abilities. Another was the belief that skills are not necessarily learned from teachers in a conventional classroom. People can pick them up in all sorts of ways.

All this echoed left-wing ideas that traditional teaching methods were not sufficiently adaptable to the needs of individual learners. Advocates of lifelong learning argue that it merely describes what has changed in education in the past decade. And there are now hundreds of schemes in which pupils learn outside the classroom.

Until now, education has been changing from below. In the next few weeks, the government will help from above. One of its main projects for lifelong learning is about to begin its first pilot programs. With funding of $ 44 million in its first year, it will coordinate a new network of "learning centers" throughout the country. Traditional institutions, such as schools and colleges, will provide training at some non-traditional places of learning, such as supermarkets, pubs, and churches. The theory is that in such places students will feel more at ease, and therefore will be better motivated, than in a classroom.

The new schemes allow consumers of education to exercise complete choice over where, what and when they learn. In the rest of the state-run education sectors (部门), the government still seems to be committed to restricting choices as much as possible. If these programs succeed, they could improve the skills of Britain's workforce.

According to the writer, the shift from "education" to "learning"______.

A．is but a change of language

B．reflects the traditional ideas in education

C．reflects the government's wish to restrict choices

D．is not just a change of language
