Why Do People Shrink？
Did you ever see the movie Honey，I Shrunk the Kids?It's about a wacky dad （who's also a scientist） who accidentally shrinks his kids with his homemade miniaturizing invention.Oops！____1_____
For older people,shrinking isn't chat dramatic or sudden at all.It takes place over years and may add up to only an inch or so off of their adult height2 （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.____2_____There are a few reasons.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） takes hold3,and the bones in the spine,called vertebrae,may break down4 or degenerate,and start to collapse into one another5._____3____But perhaps the most common reason why some older people shrink is because of osteoporosis.
Osteoporosis occurs when too much spongy 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,too?You aren't as tall at the end of the day as you are at the beginning.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.Don't worry,though.____5_____
練習(xí)：
A.They end up6 pressing closer together,which makes a person lose a little height and become shorter.
B.Once you get a good night's rest,your body recovers,and the next morning,you're standing tall again！
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.The kids spend the rest of the move as tiny people who are barely visible while trying to get back to their normal size.1
F.But why does shrinking happen at all？
答案與題解：
1.E 文章一開頭講到，在《親愛的，我把孩子們縮小了》這部電影中，一位古怪的父親不小心把自己的孩子們給縮小了，接下來的句子還應(yīng)該與這部電影有關(guān)。
2.F 從第三段的第一句話可以判斷，此處應(yīng)為詢問原因的問句。
3.A 前一句講，脊椎骨有可能退化并擠壓在一起，接下來應(yīng)選表明這種行為結(jié)果的句子。
4.C 前一句講到，當(dāng)太多松軟的骨組織壞掉并且沒有足夠的新的骨組織生成時，骨質(zhì)疏松就發(fā)生了。接下來應(yīng)首選表明這種現(xiàn)象結(jié)果的句子。
5.B 此段講的是：一個人到了晚上的時候就不如他在早起的時候高，但他不必為此著急。接下來應(yīng)首選表明不必著急原因的句子。
