ever see the movie Honey, I shrunk the kids It’s about a wacky(古怪的)dad (who’s
also a scientist) who accidentally(偶然的) shrink’s 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. (46) 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 (47) 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. (48) .
But perhaps the most common reason why some older people shrink is because of
osteoporosis (骨质疏松症). Osteoporosis 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. (49) . 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. (50) . Don’t worry, though. Once you get a
good night’s rest, your body recovers, and the next morning, you’re standing
tall again. A. They end up pressing closer together, which makes
a person lose a little height and become shorter. B. That’s
because as the day goes on, water in the disks of the spine gets compressed
(squeezed) due to gravity, making you just a tiny bit shorter.
C. Over time, bone is said to be lost because it’s not being
replaced. D. Luckily, there are things that people can do to
prevent shrinking. E. For older people, shrinking isn’t that
dramatic or sudden at all. F. There are a few reasons.
