Bringing tech into the bedroom can be more harmful than helpful. Glancing at your phone before hitting the bed may be distracting and, more important, the blue light its screen emits is known to make falling asleep more difficult. But that’s not true for all gadgets. These smart-home devices want to invade your bedroom with the aim of improving your sleep.
Muse Headband, $249
Falling asleep can be more difficult than staying asleep. With its headband, Muse hopes to train the brain to handle stress more efficiently, making it easier to relax. The gadget uses sensors to measure brain activity and then feeds that data to an app that guides you through meditation exercises. A number of less expensive or free meditation apps attempt to do much of the same without the headband.
Here One Smart Earbuds, $299.99
Sometimes earplugs or the sound of the
TV isn’t enough to drown out a partner’s snoring. Earbuds like these can help by
allowing you to progressively drown out the volume of the world around you. And if you typically need white noise to fall asleep, you can turn on a filter for that type of sound through the accompanying app.
Apple Iphone, $399-$769
Staring at the blue light coming from
your phone before bed can lower your body’s efficiency to produce melatonin, the
hormone that affects circadian rhythms.
Apple’s Night Shift feature lessens this effect by making the display colors look warmer to reduce blue light. It can also remind you to get to bed at the same time to even out your sleep habits.
S+sleep Monitor, $129.99
Many devices that track sleep require
special sensors worn on the body or embedded in a mattress. ResMed’s S+claims to monitor without making physical ontact. Instead, it uses motion-detection tehnology to pick up your tosses and turns throughout the night. It can also assess whether the temperature and lighting conditions in your room are

B.It makes it harder for your body to produce an essential chemical.
C.The Night Shift feature can probably reduce the emission of blue light.
D.Blue light reminds you to get to bed and regulates your sleep.
3.What’s the best title for the passage?
A.Sleep, something well deserved
B.Sleep, your name is gadget

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?
CP: Central Point P: Point Sp: Sub-point (次要点) C: Conclusion

Canadian experts have found that so – called self – help books may actually do more harm than good to people who really need help．Researchers say that individuals （个人） with low respect felt much worse after repeating positive statements about themselves．
In their study, psychologists Joanne Wood and John Lee sought to determine how positive thinking affected people with different levels of self – confidence．They questioned dozens of people both made and female, analyzed their self – worth and optimism by means of the standard psychological methods and then asked them to write down their thoughts and feelings．The scoring system ranged from 0 to 35．
During the experiment, the researchers asked a total of 68 participants to repeat the self-help book phrase, “I am a lovable person．” After that they measured the participants’ moods and their feelings about themselves．The results revealed that the participants in the low self – respect group who repeated the mantra （颂歌）, were feeling much worse afterwards, when compared to other participants in low self – respect group who did not repeat the phrase．Those with low self – respect who repeated the phrase scored an average of 10 points．Their counterparts （对比者） with equally low self – respect who were not asked to repeat the statement, were able to score a little higher average of 17 points．
However, individuals with high self – respect reported feeling better after repeating the positive self – statement – but only slightly．They scored an average of 31 points, compared with an average of 25 for those with equally high self – respect who did not repeat the phrase．
Professor Wood urged those who promote self – help books, magazines and television shows to stop telling people that simply repeating a positive mantra could change one’s life．First, people start following this idea and feel like they are not alone．They are told that all they have to do is just to read that book and then to repeat these positive statements in a hope that things will be better, and when it does not work for them and they realize that nothing gets better, then it is really frustration to people．
Researchers concluded: “Repeating positive self – statements may benefit certain people such as individuals with high self – respect but discourage the very people who need confidence the most．”
1.The experts tried to find out, when repeating positive self – statements, ________．
A．the different influences on people with different levels of self - confidence
B．whether males or females will get more benefit from self – help books
C．which group of people self – help books will do the greatest harm to
D．who will get the least benefit from self – help book
2.How many points did the low self – respect participants get after repeating the self – help book phrase?
A．An average of 10 points． B．An average of 17 points．
C．An average of 31 points． D．An average of 25 points．
3.So – called self – help books do some good to ________．
A．people lacking confidence
B．people with high self - respect
C．people with problems to settle urgently
D．people repeating positive self – statements

Depressed people can be very difficult to be around，and yet they need more than the usual amount of support and understanding from their friends and family.
The anger and lack of concern that a depressed person may have for people close to him or her can be very disturbing to someone who's trying to help.At such times，the sincerity of a friend or a family member is questioned when the depressed person doesn't feel worthy of someone's friendship.Withdrawal from others can make it nearly impossible to encourage a depressed person to enter into activities that may help pull him or her out of the depression.
It is frequently difficult for a depressed person to carry on a conversation.Attempts to help may be met with defensiveness and verbal attacks.While being supportive and understanding，the friend of a family member must be careful not to do too many things for the depressed person.There is a very thin line between being supportive and being overly protective.Too much“doing for” can be a disservice(帮倒忙)．
You can best help a friend or relative who is depressed by considering the following points：
◆Do not moralize.Don't pressure him or her to “put on a happy face，” or to “snap out of it.” Often the person will feel even worse after hearing such words.
◆When you are alone with your depressed friend，you might say something like，“I've noticed lately that you seem down.I care about you and would like to listen to what you're thinking about.” Then be a good listener.
◆Don't say，“I know exactly how you feel.” You probably don't.But if you've had similar experiences，sharing those may help.Say things like，“This happened to me.It might help you.” Or “I know some of what you must be feeling.”
◆Urge him or her to get professional help if necessary.Offer to accompany your friend on the first visit if it will be easier for the person.
1.．The above passage is mainly intended for ________.
A．a doctor who works with a depressed person

Electric Shocks Can Be Fatal
Government statistics recently showed that in the UK, more than 3,000 people a year experience electric shocks in their home. A smaller number of people are killed after contact with power lines outside the home. Electric shocks can cause a person’s heart or breathing to stop, can also cause burns and are potentially fatal. It is essential for people to learn basic first aid techniques to deal with such emergencies.
What to do? If you are the first person to reach someone who has had an electric shock, don’t touch them!
If they are still holding the appliance (家用电器) that has given them shock (e.g. a hair dryer), unplug it or turn off the power at its source. Under no circumstances will you try to move the appliance with your hand!
If you can’t turn off the power, use a piece of wood, like a broom handle or a chair, to separate the victim from the appliance or the power source. You may even be able to do this with a folded newspaper.
The victim must remain lying down. If they are unconscious, victims should be placed on their side. But they should not be moved if there is a possibility of neck or spine injuries unless it is absolutely necessary.
It is essential to maintain the victim’s body heat, so make sure you cover him or her with a blanket before you do anything else. If the victim is not breathing, apply mouth-to-mouth resuscitation(恢复呼吸). Keep the victim’s head low until professional help arrives.
If the electric shock has been caused by an external power line, the dangers to the victim and to anybody providing first aid are much greater.
1.What kind of passage is it?
A. An advertisement. B. A horror story.
C. A news report. D. First aid emergency advice.
2.The underlined sentence, “Under no circumstances will you try to move the appliance with your hand!” implies that ________.
A. you should move the appliance that caused it
B. you should pick up the appliance and turn off the electricity
C. it is very dangerous to touch the appliance with your hands
D. it is unnecessary to unplug the appliance with your hands
3.When a person has got an electric shock, you should ________.
A. separate the victim from the appliance and let them sit up
B. keep the victim warm and help them breathe again
C. move the victim onto their side if they have got neck injuries
D. keep the victim’s head high until professional help arrives
