Obesity Epidemic

Ask anyone why there is an obesity epidemic and they will say that it's all down to eating too much and burning too few calories. That is undoubtedly true. But it's also true that we live in an "obesogenic (肥胖基因的) environment": calorific food is plentiful and cheap and our lifestyles are increasingly sedentary.

Now, obesity researchers are increasingly dissatisfied with such explanations. They believe that something else must have changed in our environment to cause such dramatic rises in obesity over the past 40 years or so. Nobody is saying that the "big two" -- reduced physical activity and increased availability of food -- are not important contributors to the epidemic. But they cannot explain it all.

Earlier this year a review paper by 20 obesity experts set out the 9 most plausible alternative explanations for the epidemic. Here they are.

Not Enough Sleep

It is widely believed that sleep is for the brain, not the body. Could a shortage of shut-eye also be helping to make us fat?

Several large epidemiological studies suggest there may be a link. People who sleep less than 7 hours a night tend to have a higher body mass index (BMI) than people who sleep more, according to data gathered by the US National Health and Nutrition Examination Survey. Similarly, the US Nurses Health Study found that those who slept an average of 5 hours a night gained more weight during the study period than those who slept 6 hours, who in turn gained more than those who slept 7.

It's well known that obesity impairs sleep, so perhaps people get fat first and sleep less afterwards. But the nurses' study suggests that it can work in the other direction too: sleep loss may cause weight gain. One factor that could be at work here is the way sleep deprivation alters metabolism (新陈代谢). Leptin, the hormone that signals satiety (过饱), falls while ghrelin, which signals hunger, rises -- and this boosts appetite.

Climate Control

We humans, like all warm-blooded animals, can keep our core body temperatures pretty much constant regardless of what's going on in the world around us. We do this by altering our metabolic rate, shivering or sweating. Keeping warm and staying cool take energy.

There's no denying that surrounding temperatures have changed in the past few decades. In the US, the changes have been at the other end of the thermometer as the proportion of homes with air conditioning rose from 23 to 47 per cent between 1978 and 1997. In the southern states -- where obesity rates tend to be highest -- the number of houses with air con has shot up to 70 per cent from 37 per cent in 1978.

Could air conditioning in summer and heating in winter really make a difference to our weight? Sadly, there is some evidence that it does -- at least with regard to heating.

Less Smoking

Bad news: smokers really do tend to be thinner than the rest of us, and quitting really does pack on the pounds, though no one is sure why. It probably has something to do with the fact that nicotine is an appetite suppressant and appears to up your metabolic rate.

Katherine Flegal and colleagues at the US National Center for Health Statistics in Hyattsville, Maryland, have calculated that people kicking the habit have been responsible for a small but significant portion of the US epidemic of fatness. From data collected around 1991 by the US National Health and Nutrition Examination Survey, they worked out that people who had quit in the previous decade were-much more likely to be overweight than smokers and people who had never smoked. Among men, for example, nearly half of quitters were Overweight compared with 37 per cent of nonsmokers and only 28 per cent of smokers.

听力原文：W: Have you been to that new restaurant yet?

M: You mean the campus comer?

W: Yeah. That's the one. It's right across the street from the entrance to the school.

M: No. I've never eaten there. I usually have 6me to go home for lunch between classes.

W: Are you a good cook?

M: I'm quite handy in the kitchen myself. Last semester I took a course in Chinese cooking. And I must say I think I did rather well.

W: Well, in that case I'll certainly have to take the advantage of our acquaintance. Do you think you could teach something about Chinese cooking?

M: That's a great idea. Say, why don't you come home with me after geometry class? I'll mm dinner into a cooking lesson.

W: OK. If you are sure it's not too much trouble.

M: Not at all. I'll teach you what I've learnt in the cooking class. Just remind mc to stop by the grocery store after class. I have to pick up a couple of ingredients.

W: I hope this isn't turning into a huge project.

M: No way. I like to cook. Besides we have to eat anyway, right?

W: You are fight. I guess I haven't thought of it that way.

M: Oh, there is the professor. You'd better go sit down.

W: OK. See you after class.

In a country which must certainly have been a long way away from where we Rumanians live, all the young people decided to kill all the old people. It's an old, old story... What was the use of their going on living with white beards and all? They had lived their life, they'd had their time and that was that. Anyone who reached the age of fifty or a bit over—he was to be done away with.

Lots of wise old men were killed and lots of wisdom passed away with them.

Only one kind-hearted young man, so they say, took pity on his father; after all, he owed his life to him in the first place. So he hid him away in a cellar and took care of him.

Time passed and a terrible drought came. Meadows and plough lands shriveled and withered and all the springs dried up. There was terrible famine, and sickness and all kinds of troubles came upon the young people thick and fast, and their hair began to go white before its time.

They would have put up with everything as best they could, but more and worse troubles followed. The snow melted and spring was upon them without their having a single grain of seed to put in the ground.

They scraped the floors of all the barns that used to be stacked so high they could hardly hold all the grain. All the king's councilors held long talks with the king but there was nothing they could do to get themselves out of their terrible trouble. From bishop to farm worker the whole people were overcome with horror and fear at the thought that spring had come and there was nothing to sow their fields with.

The old man hidden in the cellar could see that his son was going about looking miserable all the. time. One day he asked him: "What's making you look so thoughtful, my boy? Has anyone done you any harm? Are you in trouble? Tell your father all about it. He may be able to help you, even if it's only with words."

The son told him all the troubles straight away, from beginning to end. The old man thought for a little and then he said: "Don't tell anybody anything for the time being. But when the last patches of snow melt on the fields, take your plough and go and plough up the lane in front of your house. Rake it over after that and.., stop worrying. "The boy followed the advice the old man had given him and what did he see? There came a quick spring rain and out of the ground there began to sprout wheat and maize, oats and barley and even beans and peas in some places. It seemed so wonderful that news of it spread up and down the country. It was a thing no one had ever heard of—a man's reaping where he hadn't sown.

Of course the king got to hear of it too. He quickly ordered the lad to be brought before him. So he presented himself and of course he was now considered to be the wisest of the wise.

"What did you do? How did you do it? Who told you what to do?" The king started asking him questions at once. All these questions confused the boy and he was afraid so he didn't tell him the true answer straight off. But in the end he admitted what had happened.

"Bring me your father here," the king ordered. So the old man was brought along too.

"Well, your Majesty, just think how many seeds drop on the ground when people carry them home on their carts."

The old fellow was given a royal reward; he had saved the life of the whole nation and so the boy was pardoned too for not killing him.

And ever since then, my friends, they haven't killed the old men any more.

What happened to the country when a drought came?

A．People in the country fought against it bravely.

B．People in the country suffered from hunger, diseases and all kinds of troubles.

C．People could not find their green meadows any more.

D．Many people cried.

We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we make it known to others soon. But can you imagine that a tree can talk and share news too? Of course, no tree moves lips and says words just as people do. Strange as it may sound, though, some trees do manage to communicate with each other.

Willow(柳树) trees are the best-known of these trees. When insects begin nibbling(叮咬) a willow tree, the tree sends out a special smell at once. This smell tells the other willows that harmful insects are coming near. All of them quickly make a chemical(化学物质) in their leaves. This chemical is bad to the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.

The next time when you take a walk in the woods, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees give messages to each other, too.

Willow trees send messages with _________.

A.words

B.movements

C.smells

D.sounds

The underlined word “lips” in the first paragraph means ________.A.树干

B.嘴唇

C.枝条

D.手势

The passage tells us that some of the trees can ________.A.speak just as people do

B.tell stories to others

C.communicate with each other

D.kill insects in the woods

According to the passage, the right order of the following is ________. a、 The willow tree gives out a smell. b、 The willow trees make a chemical in their leaves. c、 Insects fly away because of the chemical. d、 Insects begin nibbling a willow treeA.d-a-b-c

听力原文：W: Today in the studio we have Alberto Cortez, the well-known Brazilian advocate of the anti-global movement. He's here to talk about the recent report, stating that by 2050 Brazil will be the one of the word's wealthiest and most successful countries. Alberto, what do you say to the report?

M: You know this isn't the first time that people are saying Brazil will be a great economic power. The same thing was said over a hundred year ago. But it didn't happen.

W: Yes, but you must admit the world's a very different place now.

M: Of course. In fact I believe there's maybe some truth in the prediction this time around. First of all, though, we must remember the problems facing Brazil at the moment.

W: Such as...?

M: There's an enormous gap between the rich and the poor in this country. In Sal Paulo, you can see shopping malls full of designer goods right next door to the slam areas without proper water and electricity supplies. A lot of work needs to be done to help people in those areas improve their lives.

W: What needs to be done?

M: Education, for example. For Brazil to be successful, we need to offer education to all Brazilians. Successful countries like South Korea and Singapore have excellent education systems. Brazil needs to learn from these countries.

W: So you are hopeful for the future.

M: As I said earlier, I'm hopeful. This isn't an easy job. We need to make sure that these important opportunities for Brazil aren't wasted, as they were in the past.

听力原文：M: Well, Cynthia, our first semester at university is almost over. I can't wait for the holiday.

W: Me too, Edward! Why don't we go somewhere far away and forget these lectures and essays and all that hard work?

M: Sounds good to me. Now, how long will we have before we have to be back here on campus for the next semester?

W: We've got about six weeks, I think.

M: How about if we go to the coast? It would be great to do some swimming and surfing there.

W: The coast would be good, but let's look at our other options. There are the mountains. They're nice and cool at this time of year. And we can do some bush-walking. There's also the desert, which I really enjoyed last year.

M: What about going to Sydney? I've never been there and they say it's a great city to visit. Visitors may do lots of things there and have a good time, I've heard.

W: I agree. Sydney would be good but there are too many tourists there at this time of year. And I'd rather get away from the tall buildings and the cars. There are enough of those around here. I vote for mountains.

M: All right, then, let's do that. Now we have to decide where we're going to stay and how we're going to get there.
