An astronaut’s work may sound exciting, but living in space isn’t as fun as you think. The website www.space.com lists the disadvantages of living in space. Here are some of them.
When astronauts work outside the station during spacewalks, they have to wear special gloves. The gloves are very tight. They can hurt the astronauts’ fingernails(手指甲) and even make them fall off.
In space, you don’t have many choices in what you eat. It’s hard to get fresh fruits and vegetables. It is not OK to eat bread because it leaves crumbs(碎屑). Crumbs could fly around everywhere.
In space, it is impossible to have a good shower because water can fly all over the ship and break the machines. Astronauts have to use a special water-shooting(噴水) gun and a washcloth.
Astronauts lose their bone strength quickly during their stay in space. So far, there is no way to solve this problem. They do exercise while they’re in space to try to keep their bones strong as long as possible.

It is said that more than four million people die each year from smoking. That number is frightening.

Yet people around the world continue to smoke. In the United States, about forty-seven million adults smoke. This year, more than 430,000 Americans died of diseases which have something to do with smoking. The American Cancer Society(美國癌癥協會)says smoking harms the body greatly. It warns that smoking even a number of cigarettes is dangerous.
It’s not easy to give up smoking. However, doctors say you probably will live longer if you do stop smoking. You will feel better and look better. You also will protect the health of family members who breathe your smoke.
There is not one right way to stop smoking, doctors say. Any way can help. You can take long walks or spend time in places where smoking is not allowed. Also, you can eat a small piece of fruit or vegetable instead of having a cigarette. The sooner you stop smoking, the more you’ll reduce your chances of getting cancer and other diseases.
Stop smoking before smoking stops you!

Mount Kilimanjaro is the highest mountain in Africa and one of the largest free-standing mountains in the world, and some say, the most beautiful place on the earth.
The mountain towers 15,000 feet above the plains. Mount Kilimanjaro is in Tanzania and it covers an area of 60 miles long and 40 miles wide. Kilimanjaro is an extinct volcano(死火山), with 3 peaks. Kibo is the highest one in the center.
Because of Kilimanjaro's great height, the mountain influences(影響) its own weather. Winds incoming from the Indian Ocean are stopped upward by the mountain and drop their moisture(濕氣) as rain and snow. People have planted coffee, corn, and other crops on the lower slopes(斜坡).
