Thomas Alva Edison (爱迪生)was awarded more patents(专利) on inventions than any other American. When he died in 1931,Americans wondered how they could best show their respect for him .One suggestion was that the nation observe a minute or two of total blackout . All electric power would be shut off in homes,streets,and factories. Perhaps this suggested plan made Americans realize fully what Edison and his inventions mean to them. Electric power was too important to the country. Shutting it off for even a short time would have led to complete confusion. A blackout was out of the question.

On the day of Edison’s funeral(葬礼),many people silently dimmed their lights. In this way they honored the man who had done more than anyone else to put the great force of electricity at his countrymen’s finger tips.

2.People decided to honor Edison when______.

A. he made the first electric light

B. electric power was 100 years

C. the country realized electricity’s importance

D. he died in 1931

Under new rules posted by the Civil Aviation (航空) administration of China on Friday, pilots will have to pass a “level four” test of Mandarin Chinese, China’s official language. Those who speak with an accent that “often impedes” comprehension will not pass. These rules take effect in January 2016.

China’s 56 ethnic groups speak more than 80 languages and dialects. Even native Mandarin speakers can have trouble communicating with each other depending on the strength of their accents, which can be mutually unintelligible (难理解的).

One flight trainer illustrated the scope for linguistic confusion, especially when common English aviation terms are used. Asked if there is a problem on board, a Chinese pilot might answer in the negative with the words mei you, or “there isn’t.” But someone speaking with a heavy Sichuan accent would pronounce mei you as “May day” — unconsciously parroting the universally recognized distress call (遇难信号).

Like their international counterparts (对应物), Chinese aviators have developed codes to avoid confusion resulting from homonyms (同音异义字) or near-homonyms. They use the terms yao for one and guai for seven, which are otherwise pronounced yi and qi respectively and easily confused.

The new rule could affect all pilots, who must renew their license every six years, and adds to a growing list of burdens for the profession.

1.What does the underlined word “impedes” in Para 1 mean?

A. improves B. helps

C. misleads D. limits

2.Which of the following is true according to the passage?

A. Sichuan dialect has the contrary meaning to Mandarin.

B. Native Mandarin speakers can understand each other well.

C. It isn’t necessary for a pilot to pass the test before January 2016.

D. “May day” is a distress call in our everyday life.

3.What is the purpose of the Chinese aviators using the terms yao for one and guai for seven?

A. To avoid misunderstanding.

B. To communicate with their international counterparts.

C. To pass the test.

D. To avoid their accents.

4.What is the best title for the passage?

A. Chinese Pilots Told to Get Rid of Regional Accents

B. Chinese Pilots

C. Rich Chinese Languages

D. Hard to Be a Chinese Pilot

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.

1.Who 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.

2.The underlined word device in the 2nd paragraph is closest in meaning to ________.

A. keyboard B. smartphone C. screen D. machine

3.From the passage we know that the nanogenerator ________.

A. becomes more powerful when kept flat

B. has already come into market in the USA

C. is lightweight and flexible though expensive

D. makes it possible to produce power by walking

4.The purpose of the passage is to ________.

A. persuade people to buy the device B. bring in a new way to save energy

C. introduce a breakthrough in science D. honor Nelson Sepulveda for his contributions
