The car, Bloodhound, is designed to travel faster than 1,000 mph (1,600 km/h) —far in【48】ex______of the speed of sound and the equivalent of crossing four football pitches every second. The record of 763 mph was【49】s______in 1997 by the Royal Air Force pilot Andy Green, who will also drive Bloodhound.

The time trial is【50】sch______for 2011 and will take place in a desert in the Northern Cape of South Africa.

听力原文： Thank you all very much for coming. I will try to be as brief as possible. As I expect you’ve got your rights on the refreshments set at the back of the room which will be served the minute I finish.

OK. Before I move on to the new model, I just like to say a very warm welcome to our new marketing manager, Jane Seimes, who joined us this month. We are very glad to have her onboard.

Right, well, the regent itself, we started developing the regent as long ago as October 1999, using technology first design for our rally cars. Our engineers have worked extremely hard to bring a truly new car onto the market. Quality is guaranteed, by one of the most up-to-date production lines in the world, equipped with the lasers. They can work to a very high-level of accuracy.

Now, of course, many or most drivers won’t be thinking about that. But I think they will be very grateful for the fact that the regent is extremely economical in terms of running costs. It has the best fuel consumption rate in its class.

A lot of people say that all cars look the same these days. But that does not apply to the regent, with its special styling. And on top of that, it can be ordered in a large number of colors. More than any other car in this press range.

OK, the official launch is next week. Our advertising campaign starts tomorrow. And I' m very excited, because we are putting our main efforts into publicizing the model over the Internet. We feel we can affectively target our campaign in this way. I am very confident that the regent is going to sell very well indeed, and be part of super cars' continuing success. Because it is small and easy to park, I think we will see our best sales in cities.

Well, thank you for your attention. Now, for the refreshments.

In North America a【77】over 35 is advised to have a physical check-up and even an exercise electrocardiogram. The British, on the whole, think all this testing is unnecessary. Not many people die from exercise,【78】all, and ECGs (心电图) are notoriously inaccurate. However, two medical cardiologists at the Victoria Infirmary in Glasgow, advocate screening by exercise ECG for people over 40, or younger people al【79】at risk of developing coronary heart disease. Individuals【80】(show) a particular abnormality in their ECGs have, they say, a 10 to 20 times greater risk of subsequently developing signs of coronary heart disease, or of sudden death.
