【题目】The days of having to carry a phone charger everywhere could soon be over. Michigan researchers have revealed a major breakthrough in harvesting energy from human motion. They say it could lead to smartphones powered for a week by the motion of a swipe(重击).

Michigan State University’s low-cost device, known as a nanogenerator, has already been tested. Scientists successfully operated an LCD touch screen, a bank of 20 LED lights and a flexible keyboard, all with a simple touching or pressing motion and without the aid of a battery. The groundbreaking findings, published in the journal Nano Energy, suggest “We’re on the path toward wearable devices powered by human motion,” said Nelson Sepulveda, associate professor of electrical and computer engineering and lead researcher of the project.

“What I foresee, relatively soon, is the capability of not having to charge your cell phone for an entire week, for example, because that energy will be produced by your movement,” said Sepulveda, whose research is funded by the National Science Foundation.

Electrical energy is created when the device is compressed by human motion. The completed device is as thin as a sheet of paper. The device used to power the LED lights was palm-sized, while the device used to power the touch screen was as small as a finger. Advantages such as being lightweight, flexible and low-cost could make it a promising and alternative method in the field of Mechanical-energy harvesting.

The device also becomes more powerful when folded. Sepulveda said, “You can start with a large device, but when you fold it once, and again, and again, it’s much smaller and has more energy. Now it may be small enough to put in a specially made heel of your shoe so it creates power each time your heel strikes the ground.”

Sepulveda and his team are also developing technology that would transmit the power generated by the heel strike to, say, a wireless headset.

1Who is Nelson Sepulveda?

A. The major researcher in the project. B. A professor of engineering.

C. The fund supplier of the research. D. A journalist writing for Nano Energy.

【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
C
In seventh grade, I decided to try out for my school musical. I only made it through the first part before the drama teacher stopped me. It goes without saying that my Christmas carol didn't get me any role.
Am I embarrassed? No. Not just because it was ten years ago, but also because it's such a great story to share. Why? I think the main reason is that admitting to mistakes makes you easier to relate to. Interestingly enough, science proves this theory.
Researchers have conducted numerous studies and have concluded that when someone makes a mistake or acts in a clumsy(笨拙的) way, they are found to be more likeable. In other words, if you're competent(有能力的) at something and then you mess up, it shows your human side. This allows others to connect and relate to you, which in turn makes them like you more.
Growing up, I was the type of student who had to get straight A's and the type of athlete who always had to perform at the top of the game. The problem was that my standards were so high that I was never happy. It was only when I learned to let go and forgive myself for my mistakes that I truly felt relaxed.
When one of your close friends or family members makes a mistake, are you quick to forgive and forget? Sadly, many of us often express more sympathy(同情) for others than ourselves. With each mistake comes a lesson, and if you can learn to let go and forgive yourself, you will be better equipped to handle life's challenges going forward.
More importantly, if you're frequently worried about looking silly, you'll never be able t o get improvement at work. Even if you make a fool of yourself, it isn't the end of the world. Think about it: what's the worst that can happen? In many cases, the reward often outweighs the risk.
(1)What does the underlined part “this theory” probably refer to?
A.A mistake makes you more likeable.
B.An embarrassed person tends to act clumsily.
C.Competent people always mess up in life.
D.It's not embarrassing to share mistakes.
(2)Which of the following statements is true according to the passage?
A.The author is proud of her work.
B.The author was once a perfectionist.
C.The author always made some mistakes.
D.The author felt ashamed of her high standards.
(3)What message can be got in the last two paragraphs?
A.Making a fool of yourself when necessary.
B.Being sensitive when it comes to forgiveness.
C.Viewing mistakes as l earning opportunities.
D.Not being afraid to face your mistakes.
(4)What does the author want to tell us in the passage?
A.It's okay to make mistakes.
B.Everyone may make mistakes.
C.It's time to forgive yourself.
D.How to forgive our mistakes.

【题目】Rene Laennec was a French doctor who learned to tap on people’s chests to find out illness from an Austrian doctor named Leopold Auenbrugger.

But he was even more interested 5diseases of the heart, and he wished that he could hear heartbeats clearly. In those days, a doctor would place his head on a patient’s chest to listen, but if the patient was 6 (extreme) fat it was impossible to hear any heartbeat at all.

One day when Laennec 7(walk) in the park, he saw some girls playing with a see-saw(跷跷板). One of them scratched the end of the board while the others placed their ears against the other end. On walking up, the doctor was asked why the sounds travelled along the wood. “The sounds are magnified(放大), girls, er…”Suddenly he turned and rushed back to the hospital. Quickly8(take) some thick paper, he rolled it up like a tube and began listening to patients’ chests. He heard the heartbeats and 9 (they) breathing clearly. Laennec soon made a better instrument of wood, one he called a stethoscope(听诊器). Later, they 10 (make) of steel and rubber.
