Is a recently discovered hormone the reason why folks who lose weight can’t keep it off?
Like millions of other fat people, at 530 inches high, more than 300 pounds, Carnie Wilson was not just fat. After trying all sort of diets that didn’t work,
she has to go to the stomach – bypass surgery (胃部迂回手術), ie, have most of her stomach sewed up, only leaving tiny room to hold several tablespoonfuls at most. Result: she simply couldn’t eat the way she used to. In three years, Wilson is one third of her former weight.
Wilson’s experience is not all that unusual, and while doctors still aren’t exactly sure what is going on, a report in last week’s Journal of Medicine offers an explanation. The loss of appetite in bypass patients may be linked to a recently discovered hormone called ghrelin. Not only that, ghrelin may turn out to be one reason we feel hungry and it’s hare for didters to keep weight off.
Nowadays, researchers are careful to stress only what they know for sure. For the three conclusions, the leading Dr. David of the University of Washington says, “I feel very solid about two of them.” The first is that ghrelin levels in the bloodstream rise significantly before meals and drop afterward. The second conclusion is that ghrelin levels are higher on average in people who have lost weight from dieting.
Dr. David is less sure of the third conclusion, that bypass patients have only a quarter as much ghrelin as most people of normal weight. After all, ghrelin is produced by cells in the stomach. Years ago, leptin, a hormone was found as an appetite suppressant (食物抑制劑). But after years of trying, it had to be given up.
What doctor
s suspect is that both leptin and ghrelin are part of a complex system of brain and body chemicals that govern weight and appetite. That does not mena pharmaceutical (藥物的) weight control is forever out of the question. “In the next ten years, we will be able to develop new drugs to help people lose weight healthily and effectively.”
47．What can we learn about ghrelin according to the passage?
A．After meals ghrelin levels are higher in the bloodstream.
B．People who have lost weight have less ghreilin in their body.
C．Without ghrelin, people are really difficult to lose weight.
D．Ghrelin is something produced by cells in the stomach.
48．What is Dr. David not sure?
A．pharmaceutical weight control is impossible.
B．There is less ghrelin in the bypass patients.
C．new drugs will be developed in 10 years.
D．ghrelin levels are higher in people on diet.
49．In fact, people’s weight and appetite are controlled by
A．ghrelin and leptin B．hormone and medicine
C．brain and body chemicals D．stomach and food
50．What can we infer from the passage?
A．People with a lower ghrelin level go hungry easily.
B．Doctors managed to use leption to control the appetite.
C．Doctors are optimistic about how to lose weight healthily.
D．The loss of appetite in bypass aptient is linked to leptin

Children are our future, and it’s up to us to arm them with the tools to succeed. Sadly, today’s children are being armed with more dangerous tools like weapons （武器）, drugs and gangs. Once a relatively peaceful environment, many schoolyards of today are becoming unsafe for both students and teachers.
Home schools are available to give you choices. Home schooling provides top-quality education, flexibility, and freedom to create your own schedule. At Heritage Home School we believe the choice should be yours. Thanks in part to modern technology, home schooling information is becoming readily available across our nation. A recent study by the ITBS （Iowa Tests of Basic Skills） and TAP （Tests of Achievement and Proficiency） shows us that students of home schools do particularly well when compared with the nationwide average. In every subject at every grade level, students of home schooling scored obviously higher than those in public and private schools.
If you’re new to home schooling, you may be asking yourself, “Will home schools really work for my children?”
Fact: A nationwide study using a random（任意）selection of 1,516 families found students of home schooling to be scoring, on average, at or above the 80th percentile in all areas on standardized achievement test.
Note: The national average on standardized achievement tests is the 50th percentile. Collectively, the staff at Heritage Home School brings 65 years of experience in home schooling curriculum. We’ve placed students in the top 2 % of the nation in math and many are successfully moving on to college.
One study found that of the home schooled adults, 0% were unemployed, 0% were on welfare and 94% said home education prepared them to be independent persons. For more home schooling information, call us today toll free at（877）532-7665.

Which comes first, happiness or money? Are richer people happier? And if so, how do people get much richer? A recent study could tell you the answer.
The study looked into thousands of teenagers and found that those who felt better about life as young adults tended to have higher incomes by the time they turned 29. Those who were happiest earned an average of $8,000 more than those who were the most depressed.
The researchers, from University College London and the University of Warwick, say that very gloomy teens, no matter how tall or smart they were, earned 10% less than their peers, while the happier ones earned up to 30% more.
Happier teenagers have an easier time getting through school, college and a job interview, chiefly because they always feel better about life. It may also be true that happier people find it easier to make friends, who are often the key to homework help or networking.
A report in June suggested that professional respect was more important than dollars in terms of workplace happiness. In August scientists announced that they had found the gene for happiness in women, Alas （the same gene doesn’t appear to have the same effect on men）. And in October researchers in the UK and in the US announced that people who eat seven portions of fruit and vegetables a day report being the happiest.
The big question is: if it really is true that happier kids end up being wealthier kids, is it necessary for parents to get their kids to do the homework? The fact is that no homework will make kids happy but surely hurt their grades. Studies do show, after all, that more education leads to better-paid jobs, which may give us a deep thought.
“These findings show that the teenagers’ happiness is important to their future success,” one of the report’s authors writes. “But what is the most important is that we should find a way to help children gain more satisfaction from doing schoolwork.”
1.What conclusion can the researchers draw from the recent study?
A. Happy teenagers grow up to be wealthier.
B. Money can make people become happier.
C. Wealth has nothing to do with happiness at all.
D. Schoolwork can help teens achieve success.
2.The main reason why happier people have more chances to succeed is that ________.
A. they are easy to communicate with others
B. they are good at doing their schoolwork
C. they are hopeful and optimistic about their life
D. they eat much more fruit and vegetables a day
3.The underlined word “gloomy” in Paragraph 3 probably means “________”.
A. upset B. glorious C. happy D. wealthy
4.What can be the best title for the text?
A. The way to educate kids. B. The source of happiness.
C. How to achieve your goal. D. The secret of being wealthier.
