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.”
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

Why texting harms your IQ
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.

Texting long messages can be a pain in the neck. The repetitive action of working your fingers across the keyboard of your cell phone can cause some of the same chronic (慢性的) pain problems previously limited to those who’d spent a lifetime typing.
The possible connection is particularly worrying considering how much teens and young adults — and increasingly those in professional settings — are texting nowadays, said Judith Gold, who carried out one of the first studies on the potential connection.
Text messaging is a fairly new technology, Gold says, so this is a new area of research for those who study ergonomics (人类工程学). But “considering the similarities in body position, findings from research on overuse injuries from computers could be applicable” to texting.
“The way the body is positioned for texting – fixed shoulders and back with rapidly moving fingers – is similar to the position for typing on a computer,” Gold explained. Previous research has found pain in the elbow connected with too much thumb texting.
To look for a broader link between texting and chronic pain, Gold and her colleagues sent a questionnaire to 138 college students, asking them to report the number of text messages they sent per day (in four categories: 0, 1-10, 11-20, 21+ messages) and to point out any discomfort they felt on a body map.
The research showed an association between the number of text messages sent per day and shoulder discomfort. The effect seemed to be particularly pronounced in males, though Gold says she doesn’t know why that would be.
“What we’ve seen so far is very similar to what we see with office workers who’ve spent most of their time at a computer,” Gold said. However, Gold’s study did not take account of the amount of time the people surveyed also spent typing on computers, which could be affecting the results.
1.In the past, who usually suffered from a pain in the neck according to the passage?
A. A writer B. A typist C. A teacher D. A doctor
2. The underlined word “that” in Paragraph 6 refers to the fact that _______.
A. office workers easily suffer from the body discomfort
B. men like to text messages more
C. text messaging causes body discomfort
D. males have more shoulder discomfort
3.The passage mainly tells us _______.
A. what ergonomics is
B. texting too much causes a pain in the neck
C. whether texting is beneficial or not
D. the connection between texting and typing
4.It can be inferred from the passage that _______.
A. the study was the first one carried out by Gold
B. one positions oneself differently from computer-users when texting
C. the amount of computer-use time was calculated in the survey
D. the result of the survey was not 100% convincing

Kenya is the first country to try and protect elephants by text message. Mobile phone SIM cards inserted in the collars(项圈) of elephants automatically send a text message when they get too close to farms, allowing wildlife workers to drive them off rather than shoot them.
Hungry elephants cause big problem for farmers and villagers in some parts of Kenya looking for food and destroying homes and livelihoods in the process. Two years ago the Kenyan wildlife service had to shoot five elephants with regret and sadness who continued to destroy crops.
In an attempt to avoid such destructive actions the Save the Elephants charity installed a mobile phone SIM card in a collar that was placed on a huge bull elephant called Kimani. The conservationists( 自然环境保护者) then set up a virtual fence using a global positioning system.
Each time Kimani came near the fence, a text message was sent to workers. So far he has been prevented from going into farms fifteen times.
The project is expensive requiring five full time staff and a vehicle but it seems to be working successfully as Kimani hasn't come near a farm for four months. A similar system has now been carried out in another part of the country.
One of the biggest benefits of the project is that elephants seem to learn from one another.
Tracking and controlling one elephant can help a whole group change their habits.
The elephants can also be tracked using Google Earth software. This is also helping to prevent illegal hunting and killing as the workers know where to concentrate their resources to best protect the animals.
45. Which of the following is NOT a benefit of the project?
A. To extend elephants' habitat.
B. To protect farms from being destroyed.
C. To make more elephants change their habits.
D. To prevent elephants from being shot.
46. The fence mentioned in Paragraph 3 __________________________________ _.
A. can be seen by elephants B. actually refers to the text message
C. has prevented Kimani for 50 times D. doesn't exist in fact
47. According to the passage, the project ____________________.
A. costs just a little B. is carried out all by machine
C. seems to work out well D. is carried out across Kenya
