Effective reading of the Results and Discussion section involves identifying its structure and extracting relevant information. Read the following statements, and identify the information contained in these three parts, and match the statement of a, b, &c with1, 2, & 3 1. Limitations and how they were addressed 2. Key findings 3. Main results a. Consumption of black tea without milk caused nausea in three volunteers. (the 2nd sentence of Results) ———————— b. We found that severely obese subjects with a high prevalence of diabetes and the metabolic syndrome lost more weight in a six-month period on a carbohydrate-restricted diet than on a fat- and calorie-restricted diet (the 1st sentence of discussion) ———————— c. This study proves a principle and does not provide clinical guidance; given the known benefits of fat restriction, future studies evaluating long-term cardiovascular outcomes are needed before a carbohydrate-restricted diet can be endorsed (the last sentence of paragraph 7, Discussion) （填空格式：例如123）

Directions: In this section you will hear everything ONCE ONLY. Listen carefully and then answer the questions that follow. Questions 1 to 5 are based on an interview. At the end of the interview you will be given 10 seconds to answer each of the following five questions.
Now listen to the interview.
听力原文： Interview with Peter Moore, the Chlef-Fngineer of OPEL
Interviewer: The cars you are making today will come to the market in the year 2000. Will there be any fundamental changes？
Mr. Moore: No, the time is too short for such kind of changes. It takes 5 years at a minimum to develop a completely new car. For engines it takes even a longer time. The engine for one model usually serves for 15 or even 20 years, and there are only slight changes during this period. There is also a certain insistence on a big automaker's mind that it should keep its characteristic style. which makes its cars different. That is to say in spite of the changes an Opel still has to look like an Opel at least within several years' time. That's why there won't be any revolutionary changes in the next few years. I would say it will only be a step by step evolution.
Interviewer: What are your major considerations in the development of a new car？
Mr. Moore: The first and most important thing is to lower the consumption of petrol. So that we will not only have an economical car, but also an environmentally friendly one. The active and passive safeties for the passengers are also very important. Last but not least, a car should be comfortable and provide all facilities for an enjoyable ride. I think building a car for the future with these considerations will lead us to success.
Interviewer: Yes, at the moment it seems to become increasingly important to make a car enjoyable. The cars are becoming faster and faster.
Mr. Moore: That's right. Today a 100 HP-engine is more powerful than a 100 HP-engine 10 years ago. In this area, automakers really have achieved a great deal in increasing the efficiency of the engine.
Interviewer: But do we actually need faster cars？ Our cities are almost totally blocked up with traffic; our highways are so crowded that at any time of the day it is impossible to drive fast. The average speed in the city during rush hours is only about 20 km an hour. Everyone on a bicycle could be faster than that.
Mr. Moore: But that is only the case during rush hours. On the highways, I think there are enough opportunities for you to drive fast. People do need to drive fast in certain occasions. Besides, driving fast is a lot of fun. The increased efficiency also brings about a positive effect. Today all our cars use considerably less petrol than only a few years ago. The average consumption of petrol for all Opel models ranges about 7.45 liters per 100 kilometers. It was even hard to imagine 10 years ago.
Interviewer: How are the chances for alternative fuels like hydrogen and electricity？
Mr. Moore: From the technical point of view alternatives like methanol or alcohol are no problem. But they are still too expensive and for this reason have no big chances. Regarding the hydrogen there still exist technical problems. The amount of hydrogen that can be carried on a car as its fuel is simply still too limited. As to the electro-car we should not forget that the electrical power has to be generated first. Here are the existing problems with the power-stations. Another problem is the weight. For carrying as much energy as what is contained in a 70-liter petrol-tank, we would need a battery weighing 2.5 tons. I'm sure the electro-car will continue to develop —we already have experimental electro-cars in use —but it's impossible for them to play the main role in transport within the next few years.
Interviewer: What about solar energy？ What do you think of the so-called "solaf-car"？
Mr. Moore: There is still a great deal of research
A．is too short to include great changes
B．is completely different from the old models
C．will try hard to keep its characteristic style
D．is not greatly different from the old models
A．many of them had lived independently until their early 90s
B．they enjoy better health than people in their 70s
C．their longevity could be attributed to heredity
D．their medical expenditures are surprisingly low

听力原文： The American adventurer Steve Fossett has successfully completed the longest-ever non-stop flight in an aircraft. He took off from Cape Canaveral in Florida three days ago and has covered more than 40 thousand kilometers. He landed in southern England, ending his fight slightly earlier than expected due to technical problems. At a news conference, he described the drama at the end of his flight. "The generator light came on, and as pilots we know, that's really serious that if you don't have a generator, and all you have available for electrical powers in your battery don't last for about 25 minutes."
Steve Fossett landed in his destination ahead of scheduled time because
A．there was something wrong with the generator.
B．the pilots of the aircraft went on a strike.
C．there was no electrical power in the battery.
D．he didn't know how to generate electricity.

听力原文： President Bush said Thursday it is unrealistic to expect NATO to send more troops to Iraq. Speaking as he prepared to leave the G8 summit, the President said, however, that NATO countries could contribute in other ways. Earlier, speaking off the coast of Georgia where the site of the summit was, Sea Island, the President has suggested a role for NATO troops in Iraq that was met with some opposition by French President Jacques Chirac. The Group of Eight summit ended with participating countries agreeing among other things to fight AIDS and to promote democratic reforms across the larger Middle East.
According to the news, French President Chirac disagreed with President Bush on ______.
A．sending more NATO troops to Iraq
B．changing the way NATO acts in Iraq
C．contributing non-military NATO support for Iraq
D．playing a new role in Iraq proposed by President Bush
