At this part of the lake there occurs a deep bay or inlet(水湾, 小港), to save rounding which travelers usually strike straight【B1】from point to point, making what is called in voyageur parlance(俗话) a traverse(横渡).These traverses are subjects of【B2】anxiety, and【B3】of delay to travelers. Being sometimes of considerable extent,【B4】from four and five—and in such immense seas as lake Superior—to fourteen miles.
With boats, indeed, there is【B5】to fear,【B6】the inland craft of the fur traders can stand a heavy sea, and often ride out a pretty【B7】storm; but it is far otherwise with the bark canoes that are often used in【B8】. These frail craft can stand very little sea—their frames being made of thin flat slips of wood and sheets of bark, not【B9】than a quarter of an inch thick, which are sewed together with the fibrous roots of the pine【B10】by the natives, and rendered water-tight by【B11】of melted gum(树胶). Although light and【B12】,【B13】, and extremely useful in a country where portages are【B14】, they【B15】very tender usage; and when a traverse has to be made, the guides have always a grave【B16】with some of the most sagacious(有远见的) among the men, us to the probability of the wind rising or【B17】 consultations which are more or【B18】marked by【B19】and tediousness in proportion to the length of the traverse, the state of the weather, and the courage or【B20】of the guides.

Car makers' research and development laboratories have already proved that mixing more noise with the help of loudspeakers can reduce the unwanted noise.
Physicists have known about the technique for a long time. Sound is made up of pressure waves in the air. If two sound waves of the same frequency (频率) mix so that the highest point of one wave happens at the same time as the lowest point of the other wave, the result is no sound. Therefore, by producing a perfect copy of the noise and delaying it by half a wave cycle (周期), we can kill the unwanted noise. Using this technique many carmakers are racing to develop noise-killing systems (系统) both inside and outside the cars.
Another good thing about the use of noise-killing systems is that it saves the need for a silencer; this not only reduces the weight of a car, but also makes the motor burn less fuel and work better.
Some engineers believe that the noise-killing system will be used in most cars within a few years. But the carmakers haven't decided if they will carry it into production because it would add several hundred dollars to the cost of their cars.
Which of the following gives a general idea of how the noise-killing system works？
A．By producing pressure waves going in the opposite direction.
B．By mixing high frequency sound waves with low frequency sound waves.
C．By mixing new sound waves with the noise and sending them out together.
D．By making copies of the unwanted sound waves and letting them out a little later.
？Read the advice below about delivering a lecture.
？In most of the lines 34-45 there is one extra word. It is either grammatically incorrect or does not fit in with the sense of the text. Some lines, however, are correct.
？If a line is correct, write CORRECT .
？If there is an extra word in the line, write the extra word in CAPITAL LETTERS
Proper Preparation Prevents Poor Performance
34. eight common mistakes people frequently make in front of an audience. Second is the
35. tendency of poorly prepared speakers who to 'wing it'. Next, don't rely entirely on a
36. speechwriter—who will inevitably lack of the personal touch, which is vital. Fouth,
37. face up to tough questions and give honest answers—candour is essential to leadership.
38. At least that sounding honest is no doubt very important. As is the fifth point：the need
39. to research in the audience：the talk must be pitched at the appropriate level. The sixth
40. point is that the need to anticipate the obvious first question, which nonetheless often
41. floors the most smartest of expels. One mistake that is surely well known to even the
42. lowliest junior is there is nothing worse than a speaker who doesn't know when he to sit
43. down. Accordingly, when time your speech beforehand, standing up and delivering it.
44. Finally to drop a witty comment or anecdote to loosen up the audience. Nothing is more
45. cringe-making than a joke that falls flat.

听力原文： So, if everyone is here, I'll make a start. Now as you might know, a few months ago we asked some consultants to take a look at the way we answer the telephone across the group. They telephoned our offices and made enquiries as customers normally would. They recorded information such as how quickly the call was answered, how friendly people were and how efficiently they dealt with the enquiry.
So I'll begin with what they found out. Right, now first of all, they found out that on average we answer the phone after four rings, which isn't bad, but we can still improve on it. Secondly, friendliness. Now although some offices scored as high as 8 out of 10 for friendliness, the consultants only gave the company as a whole 6 out of 10. Once more. This wasn't as good as it should be. The consultants said that 7.5 is the minimum we should be aiming for throughout the group. And finally, efficiency. Now here, we did quite well. It deals with themselves or puts the caller through to the right person. However, there were one or two negative points which we still have to work on, such as always remembering to ask the caller's name before putting them through. So as you can see, we need to do a lot of work.
Going back to the first point, about the phone ringing four times, everyone will now be responsible for answering the phone after the third ring. This way there is no excuse for keeping a caller waiting. The point about friendliness, however, is the most important. People want to hear a cheerful voice when they call the company and feel good when they do business with, so we're going to choose some new hold music and the consultants have given us some good phrases to use on the phone. They're on the handout I gave you so, moving on to efficiency ...
•Listen to the manager talking to staff about the way they answer the telephone.
•For each question (23 -30), mark one letter (A, B or C) for the correct answer.
•You will hear the recording twice.
The information was
A．recorded by the company.
B．given by the company's customers.
C．collected by a consultancy.
