Wind turbines are efficient sources of cheap energy but also a source of concern as their huge spinning blades (葉片) frequently kill birds and bats. A new type of wind generator developed in Spain offers a creative solution to that problem.
In 2002, Spanish inventor David Yanez saw a short film about the Tacoma Narrows Bridge in the U.S., collapsing in strong wind. It was a vivid example of the powerful vibrations wind can create when it blows past a long pole, such as a car antenna or even a stick of bamboo. It gave him the idea for a new type of wind-energy generator.
“The initial philosophy or spirit was to create a generator of dreams that had all the qualities one would want: It should be as cheap as possible, need as little maintenance as possible, the setup as simple as possible,” he said.
Yanez and his friend Raoul Martin took the idea to an engineering firm, where they were told it would never work. Undiscouraged, they started experimenting on their own in a small wind tunnel they built.
Good initial results were repeated by a larger working model called Vortex (渦旋) installed in a nearby field. “What we have is a mast (桅桿), which is the top piece and acts as a blade,” Yanez said. “It’s constructed from the same material as a conventional generator, and what it does is it oscillates (振蕩), transmitting the oscillation to a conventional alternator, which by its own oscillation converts the wind’s energy into electric energy.”
Yanez said the output of the 6-meter-tall generator, and even that of smaller models, was better than expected. The Vortex creates about 30 percent less energy than a comparable bladed wind turbine, but it is lighter and cheaper to build and maintain. It is made mostly of reinforced plastic and has very few moving parts. Also, it does not create noise and—even more important for many environmentalists—it does not present a threat to passing birds.
The current prototype works at wind speeds ranging from 1.5 to 7 meters per second. The inventors say the next step is building a 12.5-meter tall bladeless generator with a 4-kilowatt capacity that could power small businesses or individual homes, or provide supplemental power to a main grid. The commercial version of the Vortex Bladeless generator should be ready for the market by 2017.
1.The author mentions a short film about the Tacoma Narrows Bridge to show ________.
A. what the initial philosophy or spirit was
B. what inspired Yanez to create the generator
C. how the bridge was destroyed in strong wind
D. how wind creates powerful vibrations
2.What do we know from the passage?
A. The original idea was considered as practical in an engineering firm.
B. Yanez and Martin’s initial tests by themselves proved to be successful.
C. The material for constructing the mast is different from that of the past.
D. The new generator is better at creating energy than a comparable bladed one.
3. What would be the best title for the passage?
A. Bladeless wind-power generator is friendly to birds.
B. Wind turbines are efficient sources of cheap energy.
C. A new generator will come onto the market by 2017.
D. Yanez has made a generator for the benefit of people.

Questions:
A.Do you think people should be decisive in the wild?
B.How to make hunting tools?
C.Do you think people should send an SOS while they are in danger?
D.How to make a fire in the wild?
E.How to set a trap to hunt animals?
F.How to build a shelter in the wild?
1.___________
Answer: If you are in a desert environment, try to build an underground shade shelter to avoid prolonged sun exposure, obviously only for hot climates.So you can be more comfortable in cooler temperatures to avoid sweating.If your environment is damp, use branches laid and criss-crossed on top of one another to create a solid and dry foundation for an open bed pad.Raise the foundation above ground level as much as possible.
2._________
Answer: Yes, I think so.For example, if you think the best survival course of action is to look for help and civilization, don’t wait 4 or 5 days before you come to this conclusion.Take action on the 1st or 2nd day if possible while you still have strength and endurance working for you.
3._________
Answer: Use dry wood and sticks to start your fire.Fire is started by using three kinds of wood: tinder, kindling, and fuel.Tinder is any kind of flammable wood shavings, usually light and wispy.You can take two pieces of dry wood, sharpen one of them and use it to drill into the other piece.Place any highly flammable objects you can find next to the drill bit.The moment the flammable object catches a spark, use a rock to swiftly tip the object onto a nest of leaves and little branches.
4.__________
Answer: Get an ordinary block of wood and hit it with a rock repeatedly until the wood sharpens.In this case, use the rock as your sharpener.You could also take a rock and break off some of the edges and then use another rock and some water like a wet stone and sharpen.In an ideal situation, obsidian stone would be used for its infamous sharpness.
5.___________
Answer: Use two more sticks to hold up a “teepee”, similar to your shelter.Place an item of your choice you think an animal will come after, if you’re lucky, the animal will be trapped.Dig a hole in the ground about 2m-3m deep and 1m-2m across.Take two thin branches and place them criss-crossed across the hole.Cover it with leaves and put something the animals like to eat.You can also put a few wooden spikes sharpened by your knife at the bottom.Don’t forget to build a ladder or you might not be able to climb out of the hole.

Let us suppose it is now about A.D. 2060. let’s make believe it is about fifty years from now. of course, things have changed and life is very different.
Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment of young and old.
What are people eating now? People are still eating food. They haven’t yet started to take on heir(繼承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.
Since there are several times as many people in the world today as there were a hundred years ago, most of our planet’s surface has to be filled. The deserts are irrigated(灌溉) with water and crops are no longer destroyed by pests. The harvest is always good.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.
People are now largely vegetarians(素食者). You see, as the number of people increases, the number of animal decreases. Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.
Such would be our life in 2060.
1. According to the text, what will be on the moon in about A.D.2060?
A. Many other animals. B. Many tourists.
C. Many plants. D. A sea.
2. What will people eat in 2060 according to the text?
A. Foods in pill form. B. Foods in gas form.
C. Biscuits in pill form. D. Foods in water form.
3.Why are people largely vegetarians in 2060?
A. There are fewer animals existing on earth.
B. People don’t like to eat meat.
C. People no longer need food.

D

Skaar didn’t panic.She figured that it was just a small fire.Her office building was huge.There were 62 floors and her desk was on the 37th floor.
Skaar called out to office mate Stephen Oksas,who also stayed late to work.But when they got to the hallway,they were met by a cloud of black smoke.Rushing back,Skaar shut the door and filled the space at the bottom of the door with her jacket to keep the smoke out.

Hopeless,they tried to break the windows,but the glass was not breakable.Everything they threw at just bounced back.
Defeated,they struggled back to the workroom.They felt weak and dizzy .Soon Skaar found Oksas had passed out.
