【题目】Carol Vaness, the well-known American opera singer, was born in San Diego and began her professional performance in San Francisco. She has sung at many of the major opera houses in the world. Unlike other world-famous male opera singers, she was particularly known for her Mozart operatic roles.

At the Metropolitan Opera in New York City where she often sings, Carol’s voice must be loud enough to be heard by four thousand people. It must reach every person in the theater, without a microphone, even when she’s singing softly. The reason Carol can project her voice that far is the way she breathes.

“When you breathe, it’s like a swimmer taking a deep breath before going underwater,” Carol explains. “You have to take a lot of air into your lungs.”

According to Carol, the main difference between pop singing and opera is “how you breathe, how much air you take in, and how you control it coming out. Regular singing is more like speaking, and it’s a lot softer.

Ever since she started piano lessons at the age of ten, Carol has loved music. As she got older, she decided to become a music teacher. When she went to college, she took singing lessons as part of her studies. Her voice teacher discovered that nineteen-year-old Carol had an exceptionally beautiful soprano(女高音) voice the highest singing voice for women.

Today, Carol performs throughout the United States and Europe and she has sung for almost twenty years. But she has never forgotten why she started singing in the first place. “Put your heart into your singing and enjoy it,” says Carol, “because singing is a great joy. That’s why I sing. In fact, that’s why everybody sings.”

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。A strong memory depends on the health and vitality (活力) of your brain. They say that you can’t teach an old dog new tricks, but when it comes to the brain, scientists have discovered that this old saying simply isn’t true. 1Give your brain a workout. Memory, like muscular strength, requires you to “use it or lose it”. The more you work out your brain, the better you’ll be able to process and remember information. 2Don’t skip the physical exercise. While mental exercise is important for brain health, that doesn’t mean you never need to break a sweat. Physical exercise helps your brain stay sharp. It increases oxygen to your brain and reduces the risk for disorders that lead to memory loss.Get enough sleep. There is a big difference between the amount of sleep you can get by on and the amount you need to function at your best. 3Keep stress in check. Stress is one of the brain’s worst enemies. Over time, stress destroys brain cells. Studies have also linked stress to memory loss.Have a laugh. 4That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specific areas of the brain, laughter engages multiple regions across the whole brain.5Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains, “healthy” fats and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it’s not just what you eat—it’s also what you don’t eat.

A. Eat a brain-boosting diet.

B. Play games with memory.

C. Laughter is the best medicine.

D. But oversleeping is not good for your brain.

E. Even skipping a few hours makes a difference!

F. You have to shake things up from time to time!

G. The human brain has an astonishing ability to adapt and change.

【题目】Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem.

Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available very soon.

Grant Stapleton from Malloy Aeronautics says the Hoverbike, which is able to get in and out of small spaces very quickly, will be a truly personal flying vehicle. "It can be moved across continents very quickly because it can be folded and packed," he adds.

Mr. Stapleton says safety was the company's main concern when developing the Hoverbike. He ays the designers solved the safety issue by using overlapping rotors (折叠旋翼) to power the vehicle. The company is testing both a one-third size model and a full-size prototype (原型) of the Hoverbike.

Inventors say their Hoverbike will most likely be used first by the police and emergency rescue teams.

In New Zealand, the Martin Aircraft Company is also testing a full-size prototype of its personal flying bike, called Jetpack. It can fly for more than 30 minutes, up t0 1,000 meters high and reach a speed of 74 kilometers per hour.

Peter Coker is the CEO of Martin Aircraft Company. He said Jetpack "is built around safety from the start, " In his words, "reliability is the most important part of it. We have safety built into the actual structure itself, very similar to a Formula One racing car. "

Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute (降落伞) that can be used should there be an emergency.

"It opens at a very low altitude and actually saves both the aircraft and the pilot in an emergency," he adds.

【1】Which of the following words can best describe the Hoverbike?

A. Powerful. B. Fast. C. Portable. D. Available.

2What make(s) flying vehicles seem practical now?

A. Modem technology. B. New safety rules.

C. Love of cycling. D. Public concerns.

3Who are expected to use the Hoverbike first?

A. People who dream of flying.

B. People who really love cycling.

C. People who design the bike.

D. People who serve public purposes.

4What's the main concern the two companies share?

A. Safety. B. Speed. C. Size. D. Design.
