Lowering the Risk of Heart Disease
Like millions of other Americans, I come from a family with a histotry of the heart disease. My father had his first three heart attacks when he was only thirty-one. _____________(46) I grew up with heart disease. It was there, but I didn’t take it seriouly.
When I was thirty-one, my blood cholesterol(胆固醇)level was measured for the first time.It was 311 mg/dl, the doctor told me- an extremely high level that put me at a very high high risk of heart disease, especially with my family history. He sent me to the National Institutes of Health(NIH)to be screened for participation in a clinical trial._____________(47)
At NIH, physicians explained the degree of risk associated with my blood cholesterol level and the nature of the experiment. This test involves putting a tube through a leg artery(动脉) up to the heart._____________(48)
Learning about the risks of the experiment as well sa the risk associated with my raised blood cholesterol level scared the life out of me. Although I was excluded from participating in the study, the experience may well have saved my life.
For the first time, I began to realize the seriousness of high blood cholesterol.___________(49) But equally important, I got a taste of what it is like to be a patient, to have tests done on me and to think of myself as sick.This was hard to take.
This experience taught me two lifesaving lessons. First, although I felt fit and strong, I was actually at high risk for heart disease because of my high blood cholesterol level. And with my family histaory, it could not be ignored.________________(50)
A Second, I could lower my blood cholesterol level simply by changing what I ate.
B I was three years old at that time.
C There is not enough oxygen in the blood.
D It was a heart attack just waiting to happen
E The trial was designed to test the effect of lowering blood cholesterol on the risk of heart disease.
F The death rate for the test was only 1 in 100, I was assured.

Why do People Shrink？
Did you ever see the movie Honey, I shrunk the kids？ It's about a wacky(乖僻的) dad (who's also a scientist) who accidentally(偶然的) shrinks his kids with his homemade miniaturizing(使小型化) invention. Oops! The kids spend the rest of the movie as tiny people who are barely visible while trying to get back to their normal size.
_________ (1)It takes place over years and may add up to only one inch or so off of their adult height (maybe a little more, maybe less), and this kind of shrinking can't be magically reversed, although there are things that can be done to stop it or slow it down. But why does shrinking happen at all？
_________(2).As people get older, they generally lose some muscle and fat from their bodies as part of the natural aging process. Gravity (the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(椎骨), may break down or degenerate, and start to collapse into one another. _________ (3).But perhaps the most common reason why some older people shrink is because of osteoporosis.
Osteoporosis(骨质疏松症) occurs when too much spongy(海绵) bone tissue (which is found inside of most bones) is broken down and not enough new bone material is made. _________ (4).Bones become smaller and weaker and can easily break if someone with osteoporosis is injured. Older people –especially women, who generally have smaller and lighter bones to begin with-are more likely to develop osteoporosis. As years go by, a person with osteoporosis shrinks a little bit.
Did you know that every day you do a shrinking act？ You aren't as tall at the end of the day as you are at the beginning. _________ (5).Don't worry, though. Once you get a good night's rest, your body recovers, and the next morning, you're standing tall again.
