Why Do Pelple Shrink?
Did you ever see the movie Honey,Ishrunk the kids?It's about a wacky(古怪的)dad(who's also a scientist) who accidentally(偶然的) shrinks his kids with his homemade miniaturizing(使小型化)inwention.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 matural aging process. Gravity(the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(推骨),may break down or degenerate, and start to collapse into one another.(48)But perhaps thje most common reason why some older people shrink is because of osteoporosis(骨質(zhì)疏松癥).
Osteoporosis occurs when too much spongy(海綿)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 lust 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.
答案解析：
46.E【解析】空格后面的內(nèi)容講述他們成年時(shí)的身高。故前面應(yīng)該是老年時(shí)。故選E。
47.F【解析】空格上段提出了一個(gè)問(wèn)題“為什么這種收縮還是會(huì)發(fā)生”。因此下面應(yīng)該是給出的原因。故選F。
48.A【解析】空格前面具體講述“地球引力對(duì)人體骨架的影響”，接著繼續(xù)談到“這種影響最終的結(jié)果”是很自然的。在用詞呼應(yīng)上：one another與A項(xiàng)中的they呼應(yīng)。故選A。
49.C【解析】空格前后句中都在提到“bone”或與“bone”相關(guān)的內(nèi)容，所以C項(xiàng)出現(xiàn)的可能性。故選C。
50.B【解析】前面說(shuō)到了這種收縮的現(xiàn)象，后面應(yīng)該進(jìn)行相應(yīng)的解釋。故選B。
