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.

It is an astonishing fact that there are laws of nature, rules that summarize conveniently

-【21】qualitatively but quantitatively - how the world works. We might【22】a universe in which there are no such laws, in which the 108 elementary particles that【23】a universe like our own behave with utter and uncompromising abandon. To understand such a universe we would need a brain【24】as massive as the universe. It seems【25】that such a universe could have life and intelligence, because being and brains【26】some degree of internal stability and order. But【27】in a much more random universe there were such beings with an intelligence much【28】than our own, there could not be much knowledge, passion or joy.

【29】for us, we live in a universe that has at least important parts that are knowable. Our common-sense experience and our evolutionary history have【30】us to understand something of the workaday world. When we go into other realms, however, common sense and ordinary intuition【31】highly unreliable guides. It is stunning that as we go close to the speed of light our mass【32】indefinitely, we shrink toward zero thickness【33】the direction of motion, and time for us comes as near to stopping as we would like. Many people think that this is silly, and every week【34】I get a letter from someone who complains to me about it. But it is virtually certain consequence not just of experiment but also of Albert Einstein's【35】analysis of space and time called the Special Theory of Relativity. It does not matter that these effects seem unreasonable to us. We are not【36】the habit of traveling close to the speed of light. The testimony of our common sense is suspect at high velocities.

The idea that the world places restrictions on【37】humans might do is frustrating. Why shouldn't we be able to have intermediate rotational positions？ Why can't we【38】faster than the speed of light？ But【39】we can tell, this is the way the universe is constructed. Such prohibitions not only【40】us toward a little humility; they also make the world more knowable.

第10题

If you're like most kids, you probably think you'll never get old. Achy joints, failing ey

esight, heart attacks: These are things you won't have to deal with for a long time, right？ So why worry now？

As it turns out, the choices you make now can make a big difference in how you feel later in life. I recently learned this lesson the hard way.

It started with an injury: a cracked shinbone caused by too much running on hard pavement. My doctor suggested a bone scan, which showed that my bones axe weaker than average. I don't have osteoporosis, a disease that causes older people to shrink in height and break bones easily. But I'm close.

For me, the diagnosis was a scary wakeup call. I'm just 27 years old, but already I'm worried about things that normally happen only to women more than twice my age. Will I break my hip if I slip on a patch of ice？ Is it sale for me to go skiing, lift heavy boxes, play Ultimate Frisbee？

Perhaps what upsets me most is the realization that I might have avoided all of this if only I had thought ahead earlier in life. Childhood and adolescence are the most important times to build strong bones. For you, there's still time. Doctors suggest a variety of foods you can eat and exercises you can do as a teenager to build strong bones for life.

Getting the right kind of bone-building nutrition and exercise as a teenager is like putting money in the hank. Your bones can stay strong, as you get older.

Unfortunately, many teenagers don't think about their bones when they order lunch or decide what to do with their free time. They'd rather snack on chips or slurp soda than think about vitamins.

And parents don't always set the best example. "I was standing by the elevator at Children's Hospital," says Susan Coupey, an adolescent medical specialist at Children's Hospital at Montefiore in Bronx, New York. "There was a 2-year-old child being fed soda by his parents."

The writer's own experience told readers that ______.

A．they begin to shrink in height and break bones easily as they grow older

B．they can avoid the writer's troubles if they think over them later in life

C．they should ask their parents to set the best examples for them

D．the choices they make now can make a big difference in how they feel later in life
