Both 【B2】______ that fuel, first into heat, then energy, some of 【B3】______ is used to do work, and some emitted as waste. And 【B4】______ your car uses more energy when the engine is racing than when it is idling, 【B5】______ does your body use more energy when you are working hard than 【B6】______ you are resting.

Your car cannot store fuel by turning it into 【B8】______ else; all gasoline not 【B9】______ remains as gasoline. But your body stores 【B10】______ energy as fat. When the gas tank is 【B11】______ empty, the car won't run; but your body can burn fat to provide more energy.
Therefore, if you want to gain weight, you must do 【B12】______ of two things: eat more calories (units of heat, therefore energy), or use less through 【B13】______ . If you want to lose weight, you do the 【B14】______ , decrease your intake of calories or increase the amount of energy you spend. There is 【B15】______ way.

听力原文： Police in London now say that more than 50 people died in yesterday's terrorist bombings and warn that the death toll could rise. Police also said that there were no more than four explosive devices involved, three on underground trains and one on a bus, and they estimated that all the bombs were relatively small containing about 10 pounds of high explosive. Commissioner Blair also denied there was any evidence to suggest that the attacks were carried out by suicide bombers but said the possibility could not be ruled out. Police said they received no warning about the attacks and would not speculate on a claim by a group calling itself "The Secret Organization of A1-Qaida in Europe" that it was behind the bombings.
We know for sure that _______.
Suppose you go into a fruiter's shop, wanting an apple—you take up one, and on biting it you find it is sour; you look at it, and see that it is hard and green. You take up another one, and that, too, is hard, green, and sour. The shopman offers you a third; but before biting it, you examine it, and you find that it is hard and green, and you immediately say that you will not have it, as it must be sour, like those that you have already tried.
Nothing can be simpler than that, you think; but if you will take the trouble to analyze and trace out into its logical elements what has been done by the mind, you will be greatly surprised. In the first place you have performed that operation of induction. You find that, in two experiences, hardness and greenness in apples went together with sourness. It was so in the first case, and it was confirmed by the second. True, it is a very small basis, but still it is enough from which to make the induction; you generalize the facts, and you expect to find sourness in apples where you get hardness and greenness. You found upon that a general law, that all hard and green apples are sour; and that, so far as it goes, is a perfect induction. Well, having got your natural law in this way, when you are offered another apple which you find is hard and green, you say, "All hard and green apples are sour; this apple is hard and green；therefore, this apple is sour." That train of reasoning is what logicians call a syllogism, and has all its various parts and terms--its major premises, its minor premises, and its conclusion. And, by the help of further reasoning, which, if drawn out, would have to be exhibited in two or three other syllogisms, you arrive at your final determination. "I will not have that apple." So that, you see, you have, in the first place, established a law by induction, and reasoned out the special particular case.
Well now, suppose, having got your conclusion of the law, that at sometime afterwards, you are discussing the qualities of apple with a friend; you will say to him, "It is a very curious thing, but I find that all hard and green apples are sour!" Your friend says to you, "But how do you know that？" You at once reply, "Oh, because I have tried them over and over again, and have always found them to be so." Well, if we were talking science instead of common sense, we should call that an experimental verification. And, if still opposed, you go further, and say, "I have heard from people in Somersetshire and Devonshire, where a large number of apples are grown, and in London, where many apples are sold and eaten, that they have observed the same thing. It is also found to be the case in Normandy, and in North America. In short, I find the universal experience of man- kind wherever attention had been directed to the subject." Whereon your friend, unless he is a very unreasonable man, agrees with you, and is convinced that you are quite right in the conclusion you have drawn. He believes, although perhaps he does not know he believes it, that the more extensive verifications have been made, the more results of the same kind are arrived at--that the more varied the conditions under which the same re- suits are attained, the more certain is the ultimate conclusion, and he disputes the question no further. He sees that the experiment has been tried under all sorts of conditions, as to time, place, and people, with the same result; and he says to you, therefore, that the law you have laid down must be a good one, and he must believe it.

Does money buy happiness？ It's sometimes said that scientists have found no relationship between money and happiness, but that's myth, says University of Illinois psychologist Ed Diener.
The connection is complex. In fact, very rich people rate substantially higher in satisfaction with life than very poor people do, even within wealthy nations, he says. "There is overwhelming evidence that money buys happiness," said economist Andrew Oswald of University of Warwick in England. The main debate, he said, is how strong the effect is.
Oswald recently reported a study of Britons who won between ＄ 2,000 and ＄ 250,000 in a lottery (彩票拍奖). As a group, they showed a boost in happiness averaging a bit more than one point on a 36-point scale when surveyed two years after their win, compared to their levels two years before they won.
Daniel Kahnman, a Nobel-Prize winner and Princeton economist, and colleagues, recently declared that the notion that making a lot of money will produce good overall mood is "mostly illusory". They noted that in one study, members of the high-income group were almost twice as likely to call themselves "very happy" as people from households with incomes below ＄ 20,000. But other studies, rather than asking for a summary estimate of happiness, follow people through the day and repeatedly record their feeling. These studies show less effect of income on happiness. Kahneman and colleagues said.
There is still another twist to the money-happiness story. Even though people who make＄150,000 are considerably happier than those who make ＄ 40,000, It's not clear why, says psychologist Richard E. Lucas of Michigan State University.
Researchers conclude that any effect of money on happiness is smaller than most daydreamers assume. "People exaggerate how much happiness is bought by an extra few thousand," Oswald said. "The quality of relationships has a far bigger effect than quite large rises in salary. It's much better advice, if you're looking for happiness in life, try to find the right husband or wife than to try to double your salary."
