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 keyboard or checking for electronic messages temporarily knocks up to 10 points off the user’s IQ. This rate of decline in intelligence compared 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(微蜂窝，微孔的) 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 percent 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 e-mail 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.”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 |

| A．the important function of advanced technology |
| B．the damage to one’s brain done by unhealthy habits |

w hich of the following shows the structure of the passage?
It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible．Everybody knows that the nicest men would become fierce tigers behind the wheel．It is all right to have a tiger in a cage, but to have one in the driver’s seat is another matter altogether.
Road politeness is not only good manners, but good sense too．It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving．On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting．A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and calm so necessary in modern traffic condition．But such behaviors of politeness are by no means enough．Many drivers nowadays don’t even seem able to recognize politeness when they see it.
However, misplaced politeness can also be dangerous．Typical examples are the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may be not able to stop in time．The same goes for encouraging old ladies to cross the road wherever and whenever they want to．It always amazes me that the highways are not covered with the dead bodies of these grannies.
An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings．Unfortunately, modern drivers can’t even learn to drive．Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users．It is high time for all of us to take this message to heart.According to the passage, troubles on the road are often caused by .
| A．road conditions |
| B．the speed of modern life |
| C．the behavior of the drivers |
D．the large number of cars  |
In the writer’s opinion, .
| A．drivers should avoid traffic jams |
| B．strict traffic rules are badly needed |
| C．unskillful drivers should be punished |
| D．drivers should show road politeness properly |
The underlined word “give-and-take” in the passage means .
| A．politeness and impoliteness |
| B．good manners and bad manners |
| C．offering help to others as much as possible |
| D．willingness to give in to each other’s wishes |
What is the best title of the passage?
| A．Road Politeness |
| B．Traffic Problems |
| C．Bad Manners on the Road |
| D．Good Drivers and Bad Drivers |
