Our space is beautiful. Looking out of the window of a space shuttle, you can see the stars more clearly than you can from Earth. It’s thrilling view. However, what’s out there can be dangerous too. And the dangerous things are often too small to see.

77.

Above Earth, where space shuttles orbit, there are thousands of chunks of space garbage. They are flying as spaceships, at about 17,000 miles per hour. Sometimes they hit spaceships. On one flight of the shuttle Columbia, the ship was hit 106 times. Most of those hits were not caused by rocks. They were caused by pieces of space garbage.

78.

What kinds of objects are floating in space today? Some are satellites that are no longer working. Others are pieces of rockets that exploded. The first explosion of a rocket in space took place in 1961. Since then, many others have occurred. An exploding rocket can send out hundreds of bits of metal.

79.

Space garbage also results from everyday even ts. Let’s say an astronaut walks outside a shuttle, taking pictures. What if he drops the camera lens cap? It becomes a piece of orbiting junk. A flying bolt may not sound like much. If it’s flying ten times as fast as a bullet, though, it can be pretty sc ary. Some space trash burns up by falling toward Earth. If it’s high up in space, though, it won’t fall to Earth. It will stay in orbit.

80.

What can be done about space trash? This may be one of the most important questions now facing NASA. One answer is to keep track of it. Radar can track a piece of space junk as small as a softball. Before launching a flight, NASA makes sure no other ships or satellites will be in the way. They could also make sure no large pieces of space junk were in the flight’s p ath. But what

about smaller things? What about a piece of metal as small as a pebble? One solution is to invent armor for spaceships. Another is to leave less garbage up there.

76.

Home is a place where one feels safe and secure but unfortunately, it is also the place where you may have serious accidents. The biggest single cause of accidents is human error! So you must take care of yourself!

77.

The design of houses can cause accidents. Balconies, fireplaces, staircases, ponds, glass doors or open-plan kitchens can all increase the risk of accidents. Hot water, household chemicals, fireplaces, matches, alcohol and sharp objects are also potential dangers. Loosing balance, clumsiness and being tired or careless can be the reasons for these accidents. What’s more, if you are under stress or when a routine is changed, you may also be under the risk of home accidents.

78.

You can see many dangerous home accidents happening around you. The most common ones are slips, falls and collisions. They are not fatal but often result in broken bones. The second most common types of accidents are burns, swallowed objects or breathed in chemicals. They especially affect children and need hospital attendance. Some other possible dangers at home are poisoning, choking, drowning, electric shocks, and animal bites. Some of these accidents may even result in death.

79.

Sometimes the simplest precaution protects you from the greatest harm! Therefore, it is important that we should educate people. The Ministry of Health can train professionals to educate nursing staff, ordinary people, voluntary workers, teachers, nursery staff and parents in home accident prevention and control. When people know first aid, they can reduce the risk of serious injuries.

80.

You must take measures to make your home a safer place. For instance, keep knives and other sharp objects in a safe drawer. Wipe up any liquids on the floor immediately in order not to slip or fall. Keep hot objects away from the reach of children. You also mustn’t leave children unattended near a bath that has water in it. If you keep furniture away from windows, you may prevent possible harm. Store all medicines, household chemicals, and so on, preferably in a locked box and do not forget to keep all dangerous substances in their original containers. In brief, if you want to protect yourself, be careful not to be sorry!
