It is impossible to know when you might find yourself lost in a forest. If you know what to do, you can survive in a forest without much trouble; but if you are not prepared, survival can be much less likely.

Keep fear at bay

It is completely natural to be afraid when you are faced with a survival situation. 1. The more your fear overcomes you, the lower your chances are of survival, as your mind is going to become clouded and panic may set in.

Stay warm

Obviously, the low body temperature is one of the primary dangers you face when you must survive in the forest2. Never stop to sleep or quit moving around unless you have appropriate shelter.

Know how to make a fire

Obviously , if you have a lighter or matches, this is not a problem. But if not, you can attempt to use a dry narrow pointed stick and a dry flat piece of wood. 3. This requires a great deal of work, but if done correctly, you will succeed.

Make some shelter

4. The easiest way to provide protection is to find a fallen tree and cover it with other branches and brush so that you can stay in the natural pit underneath the tree trunk.This is a very important aspect of being able to survive in the forest.

Stay put unless you know exactly where you are

If you can build a stable shelter and start a fire, you can survive in the forest for several days. 5. If you know where you are, travel as far as possible during the day while making sure you stop long enough before dark so that you can build another shelter.

A. Soon you will find that it’s not that difficult to survive in the forest.

B. However, if you are going to survive in the forest, you must keep your thoughts clear.

C. Make as much friction(摩擦) as possible by rubbing the pointed stick along the flat piece.

D. It is better to stay and wait for rescue.

E. Under no circumstances should we fight with the wild animals.

F. Caves and overhangs are perfect, but most likely you must build your own.

G. It is crucial that you do all you can to stay dry and keep your body temperature up.

With the press of a button, a person with severe spinal cord (脊柱)injuiy is able to walk again, thanks to the Walking Assistive Exoskeleton Robot (WAER).

Powered suits that could help paralyzed (瘫痪)people walk and others lift and carry heavy loads with ease have been a dream since late 19th century. But they can realize their dreams in the 21st century.

The 20-kilogram robot has four battery-powered motors that can run for up to three hours. Inventor Wu Chenghua, from Taiwan’s Industrial Technology Research Institute, says it has successfully been in tests on 12 patients. “We have learned from our research process that patients whose injuries are below the fourth chest joint (关节)are able to use our robot to stand, walk and sit down,” he said.

Since walking contributes to muscle exercise, Wu says patients receive some additional benefits. “In the clinical process, we would check their bone mineral density (密度),and we found that the bone mineral densities of these patients had been improved.” he said. Wu says his exoskeleton may be available for consumers by 2018.

Meanwhile, baggage handlers at Tokyo’s Haneda Airport will soon start testing a similar robot, developed by the Japanese firm Cyberdyne. The battery-powered robot weighs only 3

lift a heavy object, the machine monitors the movemen”,says Yoshiyuki Sankai, the developer and CEO of Cyberdyne.

“This robot suit monitors the signal from the human nerve (神经)system to support the waist’s movement,” Sankai said, “It self-adjusts the level support to reduce the load on the human waist, light and smart. We believe that it will change the life of paralyzed people in many ways and have a promising future.”

1.With the help of WAER, patients will probably .

A. recover from spinal cord injury

B. improve their bone mineral density

C.walk as fast as normal people

D. monitor their waist’s movement

2.What can we learn about the invention of Wu Chenghua from the passage?

A.It weighs 3 kilograms and can run for up to three hours.

B.It will soon get tested at Tokyo’s Haneda Airport.

C.It may be put into use for consumers by the year 2028.

D.It can be used by patients with injuries below the fourth chest joint.

3.How does Sankai feel about the future of the robot suits?

A. Optimistic. B. Worried.

C. Doubtful. D. Puzzled.

Healthy habits for living longer

Many of us are set in our daily habits. We eat the same meal, wear the same clothes, take the same route to work and work the same old job. But what we sometimes fail to recognize is the huge influence that our daily habits can have on our health. It is very important for us to keep our daily habits healthy. 1.

Take some exercise every day. Daily exercise does improve our health. In fact, studies show that daily exercise can add three years to our life. Opportunity for exercise is everywhere—just be creative. Whenever we can, walk to work. 2. It’s really that simple.

Eat a healthy breakfast. Researchers have found that those who eat an early morning meal are less likely to be too fat and get diseases compared with those who don’t. 3.

All in all, eating breakfast is a great and healthy way to start our day.

Have enough sleep. 4. Failing to get at least seven hours of sleep appears to increase the risk of major illnesses including cancer, heart disease, diabetes and many more.

Get chances to communicate(交流). 5. Any social communication can positively affect our health because we can have more time and chances to communicate with others. All of these can add years to our lives.

A. Not enough quality sleep can shorten our life.

B. Exercise also helps us keep away from illnesses.

C. If we live or work in a tall building, just take the stairs.

D. Breakfast-eaters also report feeling better.

E. There’s an old saying that says a good friend is cheaper than treatment.

F. Finding time for structured exercise can be pretty much impossible for many people.

G. By making just a few small changes and keeping them, we can add a few years to our life.

Some time ago I discovered that one of my chairs had a broken leg. I didn't think there would be any difficulty in getting it mended, as there are a lot of antique (古董) shops near my home. So I left home one morning carrying the chair with me. I went into the first shop expecting a friendly reception. I was quite wrong. The man wouldn't even look at my chair.

The second shop, though slightly more polite, was just the same, and the third and the fourth - so I decided that my approach must be wrong. I entered the fifth shop with a plan in my mind. I placed the chair on the floor and said to the shopkeeper, "Would you like to buy a chair?" "Twenty pounds," I said. "OK,"he said. "I'll give you twenty pounds." "It's got a slightly broken leg," I said. "Yes, I saw that. It's nothing." Everything was going according to the plan and I was getting excited. "What will you do with it?" I asked. "Oh, it will be easy to sell once the repair is done. " "I'll buy it," I said. "What do you mean? You've just sold it to me," he said. "Yes, I know but I've changed my mind. I am sorry. I'll give you twenty-seven pounds for it." " You must be crazy," he said. Then, suddenly the penny dropped. "I know what you want. You want me to repair your chair." "You're right," I said. "And what would you have done if I had walked in and said, 'Would you mend this chair for me?'" "I wouldn't have agreed to do it," he said. "We don't do repairs, not enough money in it and too much trouble. But l'll mend this for you. Shall we say for five pounds?"

He was a very nice man and was greatly amused by the whole thing.

If you want to cook something quickly, you heat it from both sides. That’s what’s happening to the West Antarctic ice sheet(南极洲西部冰盖). A new study reveals that the area under the ice sheet is far hotter than previously thought, fed by an unexpected flow of geothermal energy(地热能). While the CO2 we send out heats the atmosphere above the continent, earth is melting us ice from below.

If you were to drill (钻) deep at some place on the continents, you would find that the temperature increases about 25℃ for every kilometer deep into the hole on average. Scientists call this the geothermal gradient(地热梯度). Until recently, no one had drilled deeply enough through the West Antarctic ice to determine the geothermal gradient underground. For the new study, researchers drilled all the way through the ice and into the mud. They found that the geothermal gradient was about 200℃, which is several times the global average on continents. Few predicted this result, although it had been showed that the earth below the West Antarctic ice is unusually hot.

Even with the new discovery, though, we still don’t know exactly where the heat is coming from. One interesting possibility is volcanoes, which are under the ice. As recently as 2013, scientists were still discovering volcanoes under the ice in the area, and there may be many more.

Some people say that these volcanoes, rather than manmade climate change, are responsible for melting the area’s ice. While it’s true that heat coming from within the earth, including heat related to volcanoes, makes the melting faster, it is just one contributor to the loss of the West Antarctic ice sheet---not the main cause. Today’s study could help us understand how the whole system, including global warming, is melting the ice.

1.What’s happening to the West Antarctic ice sheet?

A. The ice sheet is getting hotter and hotter.

B. It is heated from below rather than from above.

C. The ice sheet is producing a new kind of energy.

D. It is melting from both sides.

2.What can be learned from the second Paragraph?

A. It was the first time that researchers had tried to measure geothermal gradients.

B. The geothermal gradient showed where the heat came from.

C. The result was beyond the researchers’ expectations.

D. Researchers never knew the earth under the West Antarctic ice was hot.

3.The author would probably agree that ___.

A. the new discovery is unhelpful without a certain conclusion

B. no volcano has been found to support the researchers’ idea

C. volcanoes are the most important reason for the melting of the ice

D. global warming is surely one reason for the melting of the ice

4.What’s the main idea of the passage?

A. The West Antarctic ice sheet is in danger.

B. Researchers are trying to stop global warming.

C. The West Antarctic ice sheet’s melting will bring terrible consequences.

D. It has been known how to stop the melting of the West Antarctic ice sheet.
