Those who spend more pre-bedtime hours using the Internet or watching television are more likely to report insufficient sleep, even though they sleep almost as long as people spending fewer pre-bedtime hours in front of a computer or television screen, survey findings show.
“While many people use electronic media, say, the Internet, it should be noted that the longer media use before sleep can trigger (self-perceived) insufficient sleep,” lead researcher Dr Nakamori Suganuma, of Osaka University, Japan, told the reporter.
He and colleagues obtained data on self-perceived sleep problems and the use of electronic media prior to bedtime from 5,875 altogether Japanese respondents in two separate Internet-based surveys. Their findings are published in Sleep and Biological Rhythms.
Nearly half of the respondents associated their problem with electronic media use before bedtime. Longer electronic media users were also more likely to report insufficient sleep.
“Overall, 29% of light users (less than 1.5 hours) listed electronic media use as a possible cause of their insufficient sleep. By comparison, 40% of medium users (1.5 to 3 hours) and 54% of heavy users (more than 3 hours) said the same.
However, longer Internet and television use before bedtime did not correlate with less actual sleep.
While heavy users averaged about 3 more hours in front of computer or television screens than light users, the heavy users averaged only about 12 minutes less pre-workday sleep time than light users.
Notably, Suganuma said, "Internet use affected self-perceived insufficient sleep more than TV watching not only in younger Internet users but also in middle-aged or aged Internet users."
Up to 38% of the respondents listed accessing the Internet far into the night as a possible cause for their sleep disturbance, while about 25% said watching television far into the night caused it.
The findings suggest that while heavy computer and television use before bedtime has a small effect on sleep duration, it may have a more significant effect on "sleep demand and sleep quality," Suganuma notes.

According to the survey conducted by some scientists, it is common to have difficulty sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift(轮班)work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap (小睡). When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications (药物治疗) may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism (新陈代谢) that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的)circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.

“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device of such products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to beauty or desirability.
Often such products are nothing more than money-making things for their promoter. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food Drug Administration)can require proof (证明)under the Food, Drug, and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action ,including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律诉讼), and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
【小题1】It can be inferred that ads mentioned in the text are ______.
A.objective | B.costly | C.unreliable | D.illegal |
A.if it is a drug |
B.if it is a device |
C.if its consumers make complaints |
D.if its distributors challenge FDA’s authority |
A.a product which was designed to produce electricity |
B.a product whose distributor was involved in a legal case |
C.a successful advertisement of a beauty product |
D.an example of a quality beauty product |
A.make consumers aware of the promoters’ false promises |
B.show the weakness of the law on product safety |
C.give advice on how to keep young and beautiful |
D.introduce the organization of FDA |

Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn’t it?
While such vigilant(警觉的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.
It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(预期寿命).
A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.
It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”
That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.
【小题1】Why do doctors recommend routine cancer screening for elderly people?
A.It is believed to contribute to long life. |
B.It is part of their health care package. |
C.The elderly are more sensitive about their health. |
D.The elderly are in greater danger of tumor growth. |
A.It adds too much to their medical bills. |
B.It helps increase their life expectancy. |
C.They are doubtful about necessity. |
D.They think it does more than good. |
A.It applies to women over 50. |
B.It is a must for adult women. |
C.It is optional for young women. |
D.It doesn’t apply to women over 74. |
A.They want to protect themselves against medical disputes. |
B.They want to take advantage of the medical care system. |
C.They want data for medical research. |
D.They want their patients to suffer less. |
A.The more, the better. |
B.Prevention is better than cure. |
C.Better early than late. |
D.Better care, longer life. |

Parties and social gatherings no longer excite us the same way they once did. This is not due to a lack of desire to socialize, but the smartphone.
At parties, more people are on their smartphones than on their drinks. According to a recent International Data Corporation study, well over half of all Americans have a smartphone and reach for it the moment they wake up, keeping it in hand all day. In addition, too much of society is using smartphones while driving and as a result getting into car crashes. 34 percent of teens admit to text while driving, and they confirm that text messaging is their number one driving interruption. People's attachment to their smartphones is unbelievably becoming more important than the lives of themselves and others.
Just as drivers dismiss the importance of focusing while on the road, many people also fail to recognize the significance of human interaction. When with their friends, some people pointlessly check or send text messages in the presence of a friend, which sends a message to that friend: the person I am texting is more important than you. In addition, relying on our smartphone to make friends does not give us the same advantage as being able to make new friendships in the real world. Face-to-face conversations will give us much stronger communication skills in the long run.
As many people risk their lives and the lives of people around them just to send a text or mindlessly check their massages, smartphones are in many ways more dangerous to people. The quality of this technology is de-advancing societal achievements and weakening the value of communication. Not only is the smartphone affecting our desire to interact (交流) face-to-face but it is also lowering society's ability to communicate.
【小题1】The purpose of this text is to ______.
A.call for an end to use the smartphone while driving |
B.appeal to us to pay attention to communication skills |
C.express a concern about the overuse of the smartphone |
D.advise us to be cautious about the addiction to the smartphone |
A.giving examples | B.listing figures | C.comparing facts | D.analyzing the effects |
A.by using smartphones | B.in a face-to-face way |
C.in different ways | D.under a free circumstance |
A.parties and gatherings limit their social circle |
B.people are more and more narrow-minded |
C.people's communication skills are weakened |
D.face-to-face communication becomes less important |

“When your mother scolds you, you can look elsewhere and think about other things. Just ignore her words. But remember: such a tough attitude cannot be used often.”
These words are from a series of cartoons which outline skills for children to fight against their mothers. The images have created heated debate among Chinese netizens.
Regarded as “a book for children aged 6 to 12 who are always scolded by their parents”, the cartoons, drawn by two 10yearold Beijing girls, list over 20 skills which children can use to deal with their mothers' anger such as crying, pretending to be ashamed, fleeing into the toilet and pleasing her afterwards.
Each skill is described with vivid pictures and humorous notes. The creativity of the young girls has amazed netizens, the Yangtse Evening Post reported on Thursday.
According to one of the girls' mothers, her daughter once received a poor mark in an exam, and the mother blamed her and compared her performance with another classmate. The daughter's feelings led to her creating the cartoons.
The girl's father, who first posted the pictures on his Sohu Microblog on Monday, said he hopes parents pay close attention to the pictures, allow children to feel free to develop their own characteristics and try not to criticize them so often.
The father said the cartoons aren't finished yet; his daughter will continue with them when she has time.
“The cartoons, although an individual case, reflect a modern phenomenon and some of the problems within Chinese family education,” said Yu Qinfang, an expert on family education.
According to a survey of 104 children and their parents, Yu discovered that as many as 51.9 percent of primary school students hate being urged to do things by their mothers.
“Not giving children enough time and hurrying them to do things seems to be a very tiny detail within family life, but it is potentially a huge problem which can easily be ignored by parents. A mother's blame may lead to negative feelings within her child's heart,” Yu said. “Parents should learn to blame less and be more patient.”
【小题1】What amazed Chinese netizens according to the text?
A.The girls' poor marks. |
