The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana (大麻). That is the statement of researchers who have found that tapping away on a mobile phone or computer keypad or checking for electronic messages temporarily knocks up to 10 points off the user’s IQ. This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.

It is concluded that too much use of modern technology can damage a person’s mind. It can cause a constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.

Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 per cent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an email and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.

The effects on IQ were studied by Dr Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”

1.We can learn from the passage that “infomania” ______.

A. has a positive influence on one’s IQ

B. results in the change of part of the brain

C. lies in the problem of lack of concentration

D. is caused by too much use of modern technology

2.The research mentioned in the passage is most probably about ______.

A. the important function of advanced technology

B. the damage to one’s brain done by unhealthy habits

C. the relevance between IQ and use of modern technology

D. the relationship between intelligence and working effectiveness

3.The underlined word “scrutinized” probably means “______”.

A. examined carefully B. copied patiently

C. corrected quickly D. admitted freely

4.What is the main idea of this passage?

A. The regular use of text messages and e-mails can be compared to smoking marijuana.

B. The regular use of text messages and e-mails can harm your IQ.

C. Modern technology can damage a person’s mind.

D. Electronic messages have side effects on the user’s life.

You never see him, but they're with you every time you fly. They record where you are going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book.They're known as the black box.

When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潛水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.

In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device(裝置) was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架艙). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.

Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations,and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated ( 隔絕的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

1.In Paragraph 1,the author wants to say the black box_________.

A. is an necessary device on an airplane

B. comes from a comic book

C. can prevent disasters

D. can control the function of an airplane

2.From the black box on the Yemeni airliner_________could be found.

A. the scene of the crash and the degree of the damage

B. the total number of passengers on board

C. data for analyzing the cause of the crash

D. homing signals sent by the pilot before the crash

3.Why was the black box redesigned in 1965?

A. New materials became available by that time.

B. The early models often got damaged in the crash.

C. Too much space was needed for its device.

D. The early models didn't provide the needed data.

4.The black boxes were painted orange or yellow to_________.

A. distinguish them from the colour of the plane.

B. warn people to handle them with care

C. make them easily identified.

D. obey the international standards.

5.What do we know about the black boxes from Air France Flight 447?

A. There is still a good chance of their being recovered.

B. There is an urgent need for them to be reconstructed.

C. They have stopped sending homing signals.

D.They were destroyed somewhere near Brazil.

Katharine Meyer Graham was once described as “the most powerful woman in America.? She was not a government official or elected representative. She owned and published The Washington Post. Under her leadership, it became one of the most important newspapers in the country.

Katharine Meyer was born in New York City in 1917. Her father was a successful investment banker and became an important financial official. Her family was very rich. Katharine grew up in large houses in New York and Washington. Her parents were often away from home, traveling and working, Katharine was often lonely. Katherine Meyer graduated from the University of Chicago in Illinois in 1938. In 1933, her father bought a failing newspaper, The Washington Post. It was the least successful one of five newspapers in Washington.

Katharine Graham returned to Washington and got a job editing letters to the editor of her father's newspaper. She married Philip Graham.
