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.”

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

It’s official. Denmark—as well as being the world’s best country to live in for women with the second-happiest people and one of the best healthcare systems in Europe—has the most contented babies. Or, at least, the ones who cry the least. According to research published in the Journal of Pediatrics, Danish, German and Japanese babies cry the least, while British, Canadian and Italian babies cry the most.

“I’m not surprised,” Danish parenting expert and co-author of The Danish Way of Parenting Jessica Alexander tells me. “The first year of a child’s life is considered so important in Denmark. Danish parents are much less stressed because they get good maternity and paternity leave (孕產(chǎn)假). The atmosphere is much calmer and, if mothers are getting more time off, that goes hand in hand with less stress, more contact, more routines and less crying.” She pauses before throwing in a final tip: “Oh, and Danish babies sleep outdoors a lot.”

In Denmark, a woman is given four weeks pregnancy leave followed by 52 weeks of paid leave that can be shared between parents. And Alexander thinks there is another important reason why Danish babies cry less: breastfeeding. “It’s just the done thing in Denmark,” she says of a country that has the world’s highest breastfeeding rates. “In other countries, there are continual discussions about whether you should or shouldn’t breastfeed. In Denmark, breastfeeding has never gone out of style. And everyone does it for a year.”

For Iben Sandahl, Alexander’s co-author, it comes down to the Danish attitude to life in general. “We are an honest and pure people,” she tells me. “We are surrounded by social support and are less likely to become angry, sad or annoyed when our babies are crying. And we are good at embracing (擁抱) all kinds of feelings, so we aren’t scared. Instead, we try to connect with the babies when they cry. It’s how babies communicate and it’s about trying to understand it.”

1.Which of the following can make a baby cry less?

A. An effective healthcare system.

B. More company from a parent.

C. An energetic busy mother.

D. More chances to meet fellow babies.

2.It can be learned from the text that ________.

A. something in the milk from breastfeeding can keep babies happy

B. Demark is second to none in protecting its females’ rights

C. Danish parents’ attitudes to a baby’s first year vary considerably

D. breastfeeding is a common and accepted practice in Denmark

3.When babies cry, Danish parents will probably ________.

A. try to figure out what they want

B. put them outdoors for a good sleep

C. seek social support for guidance

D. wait a moment for them to calm down

Many people think that romance（浪漫）will disappear little by little as couples grow older, but a heartbreaking video of an elderly man singing to his dying wife shows that for some, love lasts a life time.

The video was uploaded(上傳) to Facebook by the pair's granddaughter Erin Solari. In the video 92-year-old Howard is singing to his dying wife, 93-year-old Laura, with the 1940s love song "You'll Never Know".

"I love you.., always love," Laura, who is seriously ill, tells her husband in the video--before asking him to "take good care of yourself" when she's gone.

Howard then continues to sing to his wife: "You' 11 never know just how much I miss you. You'll never know just how much I care. You'll never know just how much I love you." "Isn't your grandfather lovely?" Laura says to her granddaughter, who is filming the moving moment on her phone in the hospital room.

Erin originally posted the video to her Facebook page on September 12, 2015, and it has since earned more than 3.6 million views. On her Facebook, Erin wrote down details of her grandparents' inspiring relationship. She said Howard chose to sing "You' 11 Never Know" to his wife because "the song comforted her when he went away to fight in World War II." "Their love story has moved hundreds of thousands of people throughout the world," said Erin.

1.Where did Erin Solari record the video?

A. In Laura' s house. B. At her home.

C. At the hospital D. On the way to the hospital.

2.Why did Howard sing "You' 11 Never Know" when Laura was dying?

A. To ask for her forgiveness. B. To let her feel less painful.

C. To remind her of the past. D. To give her some comfort.

3.What result does the video make?

A. It moves a lot of people. B. Solari receives many letters.

C. It helps Solari earn some money. D. It will be filmed into a movie.

You often find somebody who works around you complaining(抱怨) all the time, don't you? 1. About 70% of Americans say being around nonstop complainers sometimes has a bad influence on them. Luckily, here are 4 tips to help form positive patterns.

1．Self?awareness

When a negative(消極的) thought pops into your mind, immediately correct it. Instead of telling yourself “That's a nice shirt, but I can't afford it，” change the message to “That will look great with my black pants when I can afford it.” 2.

Of course everyone complains sometimes. But the less frequently you complain, the better you will feel.

2．Distance yourself

3. Excuse yourself and go somewhere quiet, somewhere outdoors in the fresh air. Think of something pleasant before returning. You have to take this seriously because negative people can and will pull you into the quicksand.

3．Don't try to change complainers

If you find yourself trapped in a group of complainers in a meeting or at a social event, simply choose silence. Let their words bounce off you while you think of something else. Attempting to stop the complaining can make you a target. 4. If someone says, “I hate Mondays; weekends are too short，” try to think, “I'm glad I rested up over the weekend, so I'm ready to make some improvement on that big project.”

4.5.

When someone is shouting at you angrily, throw the responsibility back at them by asking, “So what do you intend to do about it？” In most cases, complainers don't really want a solution(解決方法). They just want to speak them out. If you make them aware that they themselves have to find the solutions, they will leave you alone and find someone else to complain to. If so, you will be happy.

A．Find solutions

B．Change responsibility

C．You have got a lot of company.

D．By doing this, it will lead to positive behaviors.

E．But you can redirect the discussion in your own mind.

F．Whenever possible, escape from negative conversations.

G．You will never know what they are going to talk about.
