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. (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. 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. (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.
