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.”

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.Which of the following shows the structure of the passage?

高二英语阅读理解中等难度题查看答案及解析

There is one type of illness in the world that has a severe effect on more people than anything else and is very deadly. If untreated this illness could affect everything you do. What is this illness? Depression. Serious depression requires professional treatment. Self-induced depression is something each of us can change.

Everyone’s circumstances are different, but the causes of self-induced depression are common: low self-esteem, hurtful thinking and a bad attitude.

So how can we change the way we think, feel, and have a cheerful attitude?

First we must look at ourselves, truly and honestly examining our motives for what we wish to accomplish. If you are dissatisfied because you feel you haven’t or can’t do anything, then one step is needed—to set goals.

Always start your goals relatively small and easy to attain. Think of them as sand; one grain may be insignificant(微不足道的) but as a group they form the beach. Once you have set and attained small goals for yourself, move on to slightly larger, more challenging goals.

It takes not just setting goals but positive thinking. How can we obtain this?

There are a number of factors that can make us think negatively and one of those is diet.

In my opinion, a person who eats a lot of take-out and fast food is feeding their body junk. Start by eating better foods which give the body much NEEDED minerals. If your physical body is happy, it’s much easier for your mental body or “thinking ability” to be happy.

Next, exercise. Half an hour a day is recommended for positive well-being. Then think about good memories you had, or generally think of things that make you smile. Remember, everything you wear costs money but to wear a smile is free. A smile can be the difference between an average day and a great day.

If you follow these steps, positive change is on the way.

1.Which of the statements about depression is TRUE?

A. Depression is a kind of illness that can’t be cured like some cancer.

B. Depression can all be cured successfully by doctors in an easy way.

C. Those who suffer from depression live in the same circumstances.

D. Those who suffer from depression hold negative attitudes.

2.According to the passage we can learn that ________.

A. a practical goal can help people to achieve a sense of success

B. we shouldn’t be satisfied with small goals that are insignificant

C. we should avoid challenging goals that may result in failure

D. people can enjoy happiness even if they set inappropriate goals

3.What can we infer from the reading passage?

A. Those who can achieve small goals can surely achieve big ones.

B. Depression has something to do with the food people eat.

C. You can only exercise half an hour if you want to get rid of depression.

D. Smile makes no sense to the feeling in daily life.

It is important for countries to develop. Sometimes development can do more harm than good for a country. Therefore, this development needs to be different from past development, which polluted the environment and wasted natural resources. One possible solution to this problem now being discussed is sustainable development. It focuses on preserving the environment and natural resources. It is all about creating better health care, education, housing and improved standard of living for everyone. This is a simple idea, but one that is hard to put into practice. However, it is something that we must do, because without sustainable development our future and the lives of our children and our grandchildren will be in danger.

Nearly everything we do in our modern lives requires the use of the Earth’s natural resources. These natural resources provide the energy for many important things. The list is almost endless. For all these things, we mostly depend on fuels such as coal, gas and oil to produce energy. We are now consuming these fuels at a much higher rate than they are being produced. On top of this, burning these fuels produces carbon dioxide, which is harmful to the environment. This is why many people are pushing for the use of alternative energy sources.

Alternative energy sources can be used without running out. Some examples of the alternatives are solar energy, wind energy and hydroelectricity. As people are becoming more aware of the need to protect the environment, these types of energy are becoming more and more popular.

In many parts of the world, tentative(试验性的) steps are being taken to introduce these forms of alternative energy. For example, some people in Nigeria are training to use solar power, and in Costa Rica, people are now using hydroelectricity to provide power for their small villages. The introduction of programmes like these will hopefully help end the systematic destruction of the environment and see alternative energy promoted around the world. This will mean good things for our future, our children’s future and our grandchildren’s future.

1.We know from the passage that sustainable development _________.

A. means to develop slowly

B. can bring little good to the people

C. has ended the environmental destruction

D. is an idea being discussed

2.It is important to preserve the natural resources because they _________.

A. consume the energy for important things

B. are running out

C. provide the energy for people to use

D. are being produced at a high rate

3. Hydroelectricity means ___________.

A. using the sun to provide electricity

B. using wind power to produce electricity

C. using water power to produce electricity

D. using water to protect the environment

4. What is the author’s attitude toward sustainable development?

A. Critical.　　　　 B. Positive.

C. Tolerant.　　　　　 D. Doubtful.

A dog’s tail can tell you a lot more than you might think. Is it wagging (摇) to the left or is it wagging to the right?

“The direction of tail wagging does in fact matter，”said Giorgio Vallortigara，a professor at the University of Trento in Italy. Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog’s state of mind—whether you’re a human or another dog.

What’s the difference between a left wag and a right wag？Professor Vallortigara and his colleagues have studied 43 dogs of various breeds — German Shepherds，Beagles，Boxers，Border Collies and some mutts. They find that if a dog wags its tail to the left. it’s feeling anxious or nervous. The reason could be an unfamiliar or dangerous situation，an unfamiliar person，or an unfamiliar and possibly threatening dog. But if the tail is wagging to the right，it means the dog is feeling relaxed and approachable.

“The tail is a very important signal，”said Thomas Reimchen，a biologist at the University of Victoria in British Columbia, Canada. ”There is a lot of visual information that dogs use when communicating with each other. ”

How did the scientists figure all this information out? They had the dogs in their study watch videotapes of other dogs. When the dog on the tape wagged its tail to the right，they say the other dogs remained calm and cool. But when the dog on the tape wagged its tail to the left，the other dogs got anxious.

The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously. They suspect that it might be something the dog does without even thinking about it — kind of like when you get goose bumps if something scares or startles you. They plan to do more research to get more information about what dogs are thinking and feeling while they’re wagging. As Reimchen said，“I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before. ”

1.Professor Vallortigara’s study focused on the relationship between_________.

A. a dog’s state of mind and its owner's feeling

B. a dog’s state of mind and the direction of its tail wagging

C. a dog’s sense of direction and its state of mind

D. a dog’s intention of tail wagging and its feeling

2.According to the study，dogs which wag their tails to the left may feel_________.

A. calm B. happy C. angry D. nervous

3.It is implied in Thomas Reimchen’s words in Paragraph 4 that___________.

A. dogs’ tails play all important role in their growth

B. dogs show their feelings only by wagging their tails

C. dogs get to know others by watching tail wagging

D. dogs can understand each other by repeating tail wagging

4.How does the passage mainly develop?

A. By asking and analyzing questions

B. By making comparisons

C. By following the order of time

D. By providing examples
