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. 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.” 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 |
| C．the relevance between IQ and use of modern technology |
| D．the relationship between intelligence and working effectiveness |

Traditional surgical procedures require surgeons to make large incisions（切口）in a patient’s body in order to gain access to the organs inside . It was once common for heart surgeons , who perform highly specialized and complex procedures , to make long incisions in a patient’s chest and then split the breastbone to reach the heart . Patients who undergo surgery are often at the risk of infection , as bacteria can infect the cut in the skin . In addition , there is often a lengthy recovery period .
A surgical technique known as “ keyhole surgery ” has become common in recent years . In general , the surgeon will make a couple of small incisions around the area where the operation is going to be performed . Tubes are pushed into the holes , and a tiny camera is put into the body . The camera is attached to a large monitor screen and the doctor can see it while performing the operation . In addition to the camera , doctors also push their tiny surgical instruments through the tubes . The awkward part of keyhole surgery is that it is counterintuitive ; that is to say , if a surgeon wants to move the tool to the left , he or she must push it to the right .
Another new machine called the “ Da Vinci Surgical System ” has been tested in hospitals in the US. Unlike keyhole surgery , this robot’s moving parts are designed to copy man’s hand and wrist movement , thus providing better control and sensitivity . Sitting at a console（控制台）a few feet from the patient , the surgeon can control the instruments by moving highly sensitive pads . The area of the body is enlarged on a screen , which gives surgeons a view similar to that of a traditional surgical procedure .
The Da Vinci Surgical System has been welcomed as revolutionary by many surgeons . Patients with serious illness must undergo major surgery , but the smaller incisions typically mean a shorter recovery time . On the downside , some operations have taken up to fifty minutes longer because surgeons are inexperienced at using the new technology . As surgeons become more familiar with the machines , the time needed for surgical procedures is likely to decrease .. What can be learned about the traditional surgery according to the passage ?
| A．Long incisions are made in a patient’s chest |
| B．It often takes a longer time to do an operation |
| C．The cost of the traditional surgery is very high |
| D．The incision is likely to be infected after the operation . |
. Which of the following is one disadvantage of keyhole surgery ?
| A．It requires the use of long , thin tools and a tiny camera |
| B．The doctors can not view the inside of the patients body clearly |
| C．The direction in which a doctor moves the surgical tools is opposite |
| D．A tiny camera has to be inserted into the patient’s body in advance |
. The Da Vinci Surgical System differs from keyhole surgery in that it __________ .
| A．requires that a surgeon make more small incisions on a patient |
| B．reduces the amount of time it takes to perform a surgical procedure |
| C．allows the surgeon to use the surgical instruments more sensitively |
| D．get rid of the need for surgeons to make Large incisions on patients |
. The passage mainly tells readers about __________ .
| A．the challenges brought about by new technology |
| B．the application of new technologies in modern surgery |
| C．the reflections on the development in medical science |
| D．the benefits and drawbacks of the Da Vinci Surgical System |
One thing the tour books don’t tell you about London is that 2,000 of its residents are foxes , which fled the city about centuries ago after developers and pollution moved in . But now that the environment is cleaner , the foxes have come home , one of the many wild animals that have moved into urban areas around the world .
Several changes have brought wild animals to the concrete jungles . First of all , air and water quality in many cities has improved as a result of the 1970s’ pollution control efforts . meanwhile , rural areas have been built up , leaving many animals on the edges of suburban areas . In addition , conservationists have created urban wildlife shelters .
“ The number and variety of wild animals in urban areas is increasing , ” says Gomez Jones . One of the country’s largest populations of raccoons now lives in Washington , D.C. , and moose are regularly seen wandering into Maine towns . Peregrine falcons（猎鹰）dive from the window edges of buildings in the largest U.S. cities to hunt for pigeons .
For peregrine falcons , cities are actually safer than rural areas . By 1970 the birds had died out east of the Mississippi because the DDT , a widely used poison to kill insects , had made their eggs too thin to support life . That year , Tom Cade began raising the birds for release in cities , for cities afforded abundant food in the form of pigeons and contained none of the peregrines’ natural enemies .
“ Before they died out , some migrated to cities on their own because they had run out of natural habitats , ” Cade says . “ To peregrines , buildings are just like natural habitats . ” He has released about 30 birds since 1975 in New York , Baltimore , Philadelphia and Norfolk , and of the 20 pairs now living in the East , half are originally born in the city . “ A few of the young ones have gotten into trouble by falling down chimneys and crashing into window glass , but overall their adjustment has been successful . ”.

| B．why wildlife likes the noise and activities in the cities |
| C．that wildife refuges have been built in the cities |
| D．why wildlife is returning to cities |

In Colombia , there are some unwritten rules that people are used to , These rules are not officially established , but people do respect them . For example , on a bus , a person keeps a distance from another person , and people don’t like to touch each other . Many people come to work late because they prefer to wait for another bus if the first one is too crowded . They don’t want to have to stand too close to another person , or maybe they are afraid of starting a conversation .
A friend of mine in Colombia once said his mom got angry because he came home late , so he asked her , “ Mom , what do you think of most people arriving at their jobs so late ? ” That gave her the answer to her question since everyone knows no one wants to get on a bus that is too crowded . His mother realized at that moment that customs have a big influence on a person’s life .
Sometimes , people don’t like to make any kind of conversation or make eye contact with others . For example , when they are in line at a bank , they prefer to look up or down rather than look at other people .
Moreover , people usually look down when they are in an elevator . Not only on a bus , in line at a bank , and in an elevator do people usually avoid talking to other people , but also in the streets when they are walking , they prefer to look down and to avoid contact with others ..
