When we say older people shrink, we don’t mean they become tiny enough to fit in your pocket! We just mean that it’s common for older people to become a little shorter over time. This kind of shrinking can’t be reversed, although people can slow or stop this process. But why does shrinking happen at all?
Because of gravity (that force that keeps your feet on the ground) , cushions between the bones in the spine (脊骨), get compressed (压缩), which makes a person lose a little height and become shorter.
Another reason why some older people shrink is because of osteoporosis (骨质疏松). Osteoporosis occurs when bone is broken down and not enough new bone material is made. Over time, bone is said to be lost because it’s not being replaced. 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 can get small breaks in bones that are called compression fractures. These breaks cause collapse of the spine and over time the person with osteoporosis can become hunched over (驼背).
Did you know that every day you shrink a little, 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 due to gravity, making you just a tiny bit shorter. Don’t worry, though. Once you get a good night’s rest, your body recovers, and the next morning, you’re standing tall again!
Smoking and drinking alcohol can make this problem worse. Want to do something right now to build strong bones? I believe what I say will help you.

Prague is an ancient European city, featuring one of the most magnificent Old Towns in Europe, along with delicious food, inexpensive shopping and friendly people. Prague is also famous as being home to one of the most famous 20th century writers, Franz Kafka. The famous Czech beer is also one of the reasons to visit Prague.
The narrow streets of the older parts of the town are appealing the visitors to take nice long walk and settle in some of the many restaurants, which offer top-quality foods at a low price. The buildings there are mostly tower-shaped,and so Prague is called “city of a hundred spires.”

查看习题详情和答案>>The London Eye is a giant 135---meter tall Ferris wheel situated on the banks of the River Thames in the British capital. Since 20 January 2011, it has been officially known as the EDF Energy London Eye following a three---year deal with the company. It is the tallest Ferris wheel in Europe, and the most popular paid tourist attraction in the United Kingdom, visited by over 3.5 million people every year. The London Eye is located at the western end of Jubilee Gardens, on the South Bank of the River Thames In the London Borough of Lambeth in England, between Westminster Bridge( which has longer history than the famous Severn Bridge to the west of London) and Hungerford Bridge. When erected in 1999, it was the tallest Ferris wheel in the world, until surpassed first by the 160 m Star of Nanchang in 2006, and the 165m Singapore Flyer in 2008. A breathtaking feat of design and engineering, passengers in the London Eye’s capsules can see up to 40 kilometers in all directions. The London Eye is the vision of David Marks and Julia Barfield, a husband and wife architect team. The wheel design was used as a metaphor for the end of the 20th century, and time turning into the new millennium(千禧年). Back in 2000, the London Eye was known as the Millennium wheel. In 2009, a 4D Film Experience was added as a free extra to enjoy before your ride on the Eye. Once you get high enough and start coming down the other side, you will see people reach for their cameras. Here’s where the good stuff is right at your fingertips(or seems so). Parliament and Big Ben are beneath you, as are so many other historical things . If you are interested in other attractions in London, you can refer to the homepage.
