1、E. Small objects also lead to dangers in the space.F. Space garbage comes from satellites and rockets.76. 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. Its thrilling view. However, whats out there can be dangerous to
2、o. 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 10
3、6 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
4、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 events. Lets 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 fl
5、ying bolt may not sound like much. If its flying ten times as fast as a bullet, though, it can be pretty scary. Some space trash burns up by falling toward Earth. If its high up in space, though, it wont fall to Earth. It will stay in orbit.80. What can be done about space trash? This may be one of
6、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 t
7、he flights path. 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.7680 ADFEB(崇明)A. Most common types of accidents.B. Ways of preventing accidents.C. Nursing home injuries.D. Caus

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. Th
9、e 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
10、 tired or careless can be the reasons for these accidents. Whats 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
11、 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 a
12、nimal 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 worke
13、rs, 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 liquid
14、s on the floor immediately in order not to slip or fall. Keep hot objects away from the reach of children. You also mustnt 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
15、 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!76. F 77.

I had been through a very tiring day, and all I wanted to do was eat. I opened the refrigerator door and se
17、arched for something eatable. Luckily, I chanced to find a piece of leftover pizza from the night before. I put it onto a plate and popped it into my microwave oven. Presto! In less than two minutes, my pizza slice was ready for me to bite into. This modern-day invention, the microwave oven, should
18、be considered one of the “wonders of the world”because it is unbeatable as a food, money, and time saver.As a food saver, a microwave oven is definitely hard to beat. Almost any kind of leftover can be reheated in this type of oven, and used properly there is no worry of the food drying out. For exa
19、mple, spaghetti is a mess to try to reheat on top of the stove. It dries out terribly and will stick to the bottom and sides of a saucepan. The spaghetti will also scorch(烧焦) easily if one is not careful. But with a microwave oven, this is a different story with a happier ending. The spaghetti will
20、remain saucy, will not stick, and will not scorch. The Italian food will be as good as it was the first time around.Another “wonder”about the microwave oven is the money that it saves. Leftovers that would normally be thrown out can be saved and reheated. This saves food; thus, it saves money. Also,
21、 these ovens are faster; therefore, they are electricity. In these days that can be a blessing.Best of all, however, is the time that a microwave oven can save. As a general rule, microwave cooking takes one-third the time that a conventional oven does. Imagine what a delight this would be after a t
22、iring day at work, school, or, better yet, shopping! For instance, to bake a medium-sized potato takes only eight to ten minutes in a microwave oven. So in the time it would take to fry up a hamburger, one could have a hot baked potato to go with it. In addition to speedy cooking, a microwave is won
23、derful for defrosting (解冻) meat. On low power this oven can defrost any kind of meat in less than fifteen minutes. This is a real lifesaver when company drops in right at dinnertime.Indeed, microwave ovens should be considered one of the modern wonders of the world. I know that it was a wonder for m

25、r Tough TimesSonja Lyubomirsky, an author, has researched the science of happiness for years. Here are her tips to help you cope with a bad economy, and increase your bursts of happiness throughout the day.76. _“You could spend a lot of time thinking deeply,” says Lyubomirsky. “But that just makes y
26、ou feel even more pessimistic, more out of control, and affects your self esteem. Your relationships will suffer and your job performance will suffer.”Get rid of pessimism. One of the most effective ways to cope when things are difficult is to adopt a positive thinking strategy. “What can I learn fr
27、om this? Times are tough, Ive been furloughed at work, but I can spend more time with the kids, adopt a new hobby, or learn a new set of skills.”77. _Now more than ever we need each other to survive. Lyubomirsky found that doing good things for friends, family, or strangers can make you happier. Thi
28、nk of practical, everyday gestures that can make someones life a little bit easier. For example, Lyubomirsky says, “Maybe now many of us cant afford to take a cab to the airport, so offer to give a friend a ride.”78. _You dont need an expert to tell you that relationships are critical to happiness.
29、Not being the bread-winner anymore or not being able to fulfill your kids needs can weigh down hard on your family life. But the trick is to stop feeling guilty and focus on caring for your loved ones.“I was at a psychology conference where an expert was talking about the effects of this economy on
30、families and how parents cant afford to buy their kids luxuries like toys anymore,” says Lyubomirsky. “But what they dont realize is that kids dont care about toys what they care about is parents being grumpy and taking it out on them.”79. _“If you find a happy person you will find a project,” says
31、Lyubomirsky. “Happy people all have goals they care about.”Commit yourself to a project whether it is a business you want to start or a dance you want to learn. But its also important to remember to be flexible in these times. Dont get frustrated if circumstances are stopping you from meeting your goals. Adopt and change!“If your spouse has lost their job you might have to change your goal,” says Lyubomirsky. “Or you might have to l
