What Makes Me the Weight I Am?
There's no easy answer to this question.Your genetic makeup,the physical traits that get passed down to you from your parents,plays a big part in determining your size and weight. ______(46)But if your parents are smaller than average,you may want to rethink that professional basketball career!
The same goes for your body type.Have you ever heard someone say a person is"big boned"?It's a way of saying the person has a large frame,or skeleton.Big bones usually weigh more than small bones. ______(47) Like your height or body type,your genes have a lot to say about what your weight will be.But that's only part of the story.Being overweight can run in someone 's family , but it may not be because of their genes._______ (48 ) And even though some kids gain weight more easily than others , when they eat right and exercise , most kids can be a healthy and happy weight that's right for them.It's true the way you live can change the way you look.

Napping to a Healthier Heart?
1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.
2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP.Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.
3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.
4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart disease patient should affect that person's treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the Journal of the American Medical Association.
5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children.But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps.
6 The researchers say napping may improve heart health by reducing stress.They say the research suggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.

People who take regular afternoon naps______.
A:where fewer people die from heart problem
B:whether they have the risk of heart attack,heart failure or stroke
C:would probably have lower rates of heart disease
D:how to test a person's NT-proBNP level in the blood by himself
E:his heart muscle would be under pressure in some way
F:that napping is of great benefit to women too

Smart Exercise

Doctors are starting to find more and more information that suggests a connection
between exercise and brain development.Judy Cameron,a scientist at Oregon Health and
Science University,studies brain development.According to her research,it seems that
exercise can make blood vessels,including those in the brain,stronger and more fully
developed.Dr. Cameron claims this allows people who exercise to concentrate better. As
she says:"While we already know that exercise is good for the heart,exercise can literally
cause physical changes in the brain."
The effects of exercise on brain development can even be seen in babies.Babies who
do activities that require a lot of movement and physical activity show greater brain
development than babies who are less physically active.With babies,even a{ittle
movement can show big results. Margaret Barnes , a pediatrician（儿科医师）,believes in
the importance of exercise.She thinks that many learning disabilities that children have in
elementary school or high school can be traced back to a lack of movement as babies.
"Babies need movement that stimulates their five senses.They need to establish a
connection between motion and memory.In this way,as they get older,children will begin
to associate physical activity with higher learning,"says Margaret.
Older people can beef up their brains as well.Cornell University studied a group of
seniors ranging in age from seventy to seventy-nine. Their study showed a short-term
memory increase of up to 40 percent after exercising just three hours a week.The exercise
does not have to be very difficult,but it does have to increase the heart rate.Also,just like
the motion for infants,exercise for older people should involve some complexity.Learning
some new skills or motions helps to open up memory paths in the brain that may not have
been used for a long time.
For most people,any type of physical activity that increases the heart rate is helpful.
The main goal is to increase the brain's flow of blood.And your brain can benefit from as
little as two to three hours of exercise a week.

The expression"beef up"in paragraph 3 means
A:control.
B: strengthen.
C:operate.
D: encourage.

Personality and Career

1.When you select your career,there's a whole lot more to it than assessing your skills and matching them with a particular position.If you ignore your personality,it will hurt you long-term regardless of your skills or the job's pay.There are several areas of your personality that you need to consider to help you find a good job.
2. There are isolating（使孤立）jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy.Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.
3.Most jobs these days have some elements of change to them,but some are more than others. If you need stability in your life,you may need a job where the changes don't happen so often.Other people would be bored of the same daily routine.
4.There are people who are happy to spend more than 40 hours a week on a computer,while there are others who need a lot of human interaction throughout the day.Again,these are extremes and you'll likely find a lot of positions somewhere in the middle as well.

Obesity:the Scourge of the Western World
Obesity is rapidly becoming a new scourge of the western world,delegates agreed at the 11th European Conference on the issue in Vienna Wednesday to Saturday. According to state-ments before the opening of the conference一of 2,000 specialists from more than 50 countries一1.2 billion people worldwide are overweight,and 250 million are obese.
Professor Bernhard Ludvik of Vienna General Hospital said:“Obesity is a chronic ill-ness.In Germany,20 percent of the people are already affected,but in Japan only one per-cent.”But he said that there was hope for sufferers thanks to the new scientific discoveries and medication.
Professor Friedrich Hopichler of Salzberg said:“We are living in the new age(but)with the metabolism of a stone-age man.”“I have just been to the United States.It is really terni-ble.A pizza shop is springing up on every corner. We have been overrun by fast food and Co-ca-Cola-ization.”
Many of the experts stressed that obesity was a potential killer. Hopichler said:“Eighty percent of all diabetics are obese,also fifty percent of all patients with high blood pressure and fifty percent with adipose tissue complaints.”“Ten percent more weight means thirteen percent more risk of heart disease.Reducing one's weight by ten percent leads to thirteen percent lower blood pressure.”
Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs.“Though the health insurance pays for surgery( such as re-ducing the size of the stomach)when the body-mass index is more than 40.That is equivalent to a weight of 116 kilograms for a height of 1.70 meters.One should start earlier.”
Ludvik said that prevention should begin in school.“Child obesity(fat deposits)correlates with the time which children spend in front of TV sets.”The consequences were only apparent later on. No more than fifteen percent of obese people lived to the average life ex-pectancy for their population group.

What is the correlation between body weight and heart disease and blood pressure?
A: Ten percent less body weight means ten percent less risk of heart disease and high blood pressure.
B: Thirteen percent more body weight means ten percent more risk of heart disease and high blood pressure.
C: The more body weight one gains,the more risk of heart disease and high blood pressure he has.
D: The less body weight one gains,the more risk of heart disease and the less risk of high blood pressure he has.
