A Leap（跳跃）to Honor
Leaping on a narrow balance beam（平衡木） is not easy. But Lola Walter, a 13-year-old gymnast, is an expert at it.
To perfect her skills, Lola 36 for four hours a day, five days a week. At the state championships in March, she finished seventh out of 16 girls.
That’s especially impressive, 37 she is legally blind, born with a rare condition that causes her eyes to shift constantly. She often sees double and can’t _38 how far away things are.
When she was little, her mom 39 that even though she couldn’t see 40 , she was fearless. So her mom signed her up for gymnastics when she was three. She loved the 41 right away and gymnastics became her favorite.
Though learning gymnastics has been more 42 for her than for some of her tournaments, she has never quit. She doesn’t let her _43 stop her from doing anything that she wants to.
She likes the determination it takes to do the sport. Her biggest 44_ is the balance beam. Because she has double vision, she often sees two beams. She must use her sense of touch to help her during her routine. Sometimes she even closes her eyes. “You have to 45_ your mind that it’ll take you where you want to go,” says Lola.
To be a top-level gymnast, one must be brave. The beam is probably the most 46 for anyone because it’s four inches wide. At the state competition, Lola didn’t fall 47 the beam. In fact, she got an 8.1 out of 10---- her highest score yet.
Lola doesn’t want to be 48 differently from the other girls on her team. At the competitions, the judges don’t know about her vision _49 _. She doesn’t tell them, because she doesn’t think they need to know. Her mom is amazed by her _50 attitude.
Lola never thinks about 51__. She is presently at level 7 while the highest is level 10 in gymnastics. Her 52 is to reach level 9. She says she wants to be a gymnastics coach to pass down what she’s learned to other kids 53 she grew up.
Lola is 54 of all her hard work and success. She says it’s helped her overcome problems in her life outside gymnastics, too. Her 55 for others is “just believe yourself”.

Microwaves may be great at warming up food, but what about warming people?
Using microwaves to directly heat owners of a room would save much of the energy wasted by heating walls and furniture. And despite popular ideas about microwaves, this technique would be safe, according to Charles R. Burlier of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.
To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 milliwatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs between 35 and 50mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000 mw. / sq. cm.
In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector (运动感应器)would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwave oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical.)
While it might be some time before homeowners are comfortable enough with the idea to set up whole-body microwave heaters in houses, Buffler says microwaves may attract livestock(家畜) farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly.
1.Which of the following can tell the main idea of the passage?
A．A new heating system. B．A new microwave oven.
C．A popular technique. D．The magnetron.
2.According to Paragraph 2, which of the following does not describe the characteristics of a microwave heater?
A．It directly heats people in a room.
B．It heats walls and furniture in a room.
C．It is safe.
D．It saves energy.
3.The test conducted by Buffler shows that when a person feels comfortable warmth, he receives about ________________.
A．20 mw. / sq. cm. B．40 mw. / sq. cm. C．60 mw. / sq. cm. D．85 mw. / sq. cm.
4.According to Paragraph 4, which of the following fills the room with low-power microwaves?
A．The magnetron. B．The motion detector.
C．The microwave oven. D．The radiation-absorbing chemical.
5.Which of the following statements about microwave heaters would Buffler most probably agree with?
A．Microwave heaters will soon be widely used by homeowners.
B．Microwave heaters sometimes make people feel uncomfortable.
C．Perhaps microwave heaters will be first used by livestock farmers, who wish to protect their lambs in winter.
D．Microwave heaters cannot be accepted by the public because they are somewhat unsafe.

Christmas is long gone. and Valentine’s Day is a distant memory. That means it's a slow time for jewelers, and a good time for you to make a purchase. Whether you’re out shopping for gold, or silver, here fife a few things you need to know:
What determines price?
The purity of the metal is one of the elements that determines the price. Gold purity is indicated with a stamp of 10K, 14K, 18K, or 24K. And different countries have their own standards. For example, for a piece to be considered gold in the US, it must be at least 10K. In Britain and Canada: 9K. In Italy and France: l 8K. Anything over l 8K is really too soft for everyday wear. That’s why jewelry stores in the US sell mostly 14K.
How much can you expect to pay?
That depends on the weight of the metal and the gemstone(宝石). So keep that in mind, especially when buying online. To keep yourself from getting ripped off, ask yourself the following:
●How long has the company been around?
●What is its return policy?
● Is the jewelry featured on the website visible from all directions?
● Is the company transparent with the gram weights and the size of the gemstones?
Yellow gold? White? Rose?
Yes, it's confusing, and while this is largely a personal decision, there fife a few things to keep in mind. For starters. white or rose gold costs about l 0% more than yellow gold. If you want the “look for less”, consider gold. plated jewelry. “Gold plated” and “gold overlay” mean the same thing and guarantee a thicker layer of finish than “vermeil” which is a flash finish that is thinner and less consistent, but more affordable. Buy vermeil finished pieces you want for a season or two just to follow the fashion. For pieces you want to wear for a lifetime, solid gold is best.
What about sterling silver(标准纯银)?
Sterling silver has been。an alternative for white gold during the difficult economy, and while it used to be more popular with just the younger these days it has much more mass appeal. So much so that retailers are now offering fine gemstones with silver--something you used to see only with gold.
Keep in mind that in the US. the sterling silver standard is 92.5% real silver. Don’t buy it if there isn’t a “925” stamp on it. And keep in mind that the lower price you’re paying for silver means more maintenance. To keep silver jewelry from becoming less shiny, consider keeping a piece of chalk in your jewelry box.
1.According to the passage, the underlined phrase “getting ripped off” in Paragraph 3 probably means “_______”.
A．being charged B．being cheated C．being affected D．being attracted
2.Which of the following is relatively good for only wearing a short time?
A．A 14K necklace. B．A gold-plated ring.
C．A vermeil ear ring. D．A gemstone necklace.
3.We call infer from the last paragraph that silver jewelry should be kept ________
A．in a dry place B．in a cold place C．in a wet place D．in a hot place
4.The author writes the passage mainly to ________.
A．encourage young people to buy fashionable jewelry
B．tell people the best time to purchase gold and silver
C．introduce the real value and popularity of gold and silver
D．inform people of the factors to consider in buying jewelry
According to the
US government, wind farms off the Pacific coast could produce 900 gig watts of
electricity every year. Unfortunately, the water there is far too deep for even
the tallest windmills(see picture)to touch bottom. An experiment under way off
the coast of Norway, however, could help put them anywhere.
The project, called Hywind, is the world’s first large-scale deepwater wind turbine(涡轮发电机).Although it uses a fairly standard 152-ton,2.3-megawatt turbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture),a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cable(缆索)；these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywind’s stability(稳定性)in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September.
To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spar’s to design a new kind of wind turbine, one whose gearbox(变速箱) sits at sea level rather than behind the blades (see picture )
Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available.
1.
The Hywind project uses totally new technology to ensure the stability of _______.
A. the cables which tie the spar to the ocean floor
B. the spar which is floating in deep-sea water
C. the blades driven by strong and steady sea wind
D. the stones filled in the spar below the sea surface
2.
To balance a bigger turbine high on a flatting spar, a new type of turbine is to be designed with its gearbox sitting ____________.
A. on the sea floor B. on the spar top
C. at sea level D. behind the blades
3.
Wide applications of deepwater wind power technology can ____________.
A. solve the technical problems of deepwater windmills
B. make financial profits by producing more turbines
C. settle the arguments about environmental problems
D. explore low-carbon power resources available at sea
