Below is some advice on how to sleep better.
1. Maintain a regular bed and wake time schedule
Go to bed at the same time every night. Choose a time when you normally feel tired, so that you don’t toss or turn. Try not to break this routine on weekends when it may be tempting to stay up late. If you want lo changeyour bedtime, help your body adjust by making the changein small daily increments, such as 15 minutes earlier or later each day. As with your bedtime, try to maintain yourregular wake-time even on weekends.
2.Fight after-dinner drowsiness（睡意）
If you find yourself getting sleepy before your bed-time, get off the couch and do something mildly stimulating to avoid falling asleep, such as washing the dishes, calling a friend, or getting clothes ready for the next day. If you give in to the drowsiness, you may wake up later in the night and have trouble getting back to sleep.
3. Keep your room dark and cool
When it’s time to sleep, make sure that your environment is dark. Even dim light —especially those from TV or computer screens —can confuse the body clock. Heavy curtains or shades can help block light from windows, or you can try an eye mask to cover your eyes. The temperature of your bedroom also affects sleep. A bedroom that is too hot or too cold can interfere with quality sleep.
4. Turn off your television
Many people use the television to fall asleep or relaxat the end of the day. You may even have a television inyour bedroom. However, television actually stimulates themind, rather than relaxing it. Part of this is due to con­tent. Late night news and prime time shows frequently have disturbing, violent material. Even non-violent pro­gramming can have commercials that are jarring and loud.
5. Exercise early
Exercise helps promote restful sleep if it is done sev­eral hours before you go to bed. Exercise can help you fall asleep faster and sleep more soundly— as long asit ’s done at the right time. Try to finish exercising at least three hours before bed or work out earlier in the day.
6. Consult your doctor
Use a sleep diary and talk to your doctor. Note what type of sleep problem is affecting your sleep or if you aresleepy when you wish to be awake and alert. Try these tips and record your sleep and sleep-related activities in a sleep diary. If problems continue, discuss the sleep diary with your doctor. There may be an underlying cause and you will want to be properly diagnosed. Your doctor will help treat the problem or may refer you to a sleep specialist.

A team of US psychologists have found that talking to another person for ten minutes a day helps with memory.
"Socializing is just as effective as more traditional kinds of mental exercise in boosting memory and intellectual performance," Oscar Ybarra, a psychologist at the University of Michigan Institute for Social Research, said in a statement.
In one investigation, they analyzed data on 3610 people, aged 24 to 96.
They found that the higher their level of social interaction (交流), the better their cognitive (认知的) functioning.  Social interaction includes getting together or having phone chats with relatives, freinds and neighbors.
In another experiment, the researchers conducted lab tests on 76 college students, aged 18 to 21, to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests.
The students were divided into three groups: the social interaction group had a discussion of a social issue for 10 minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group (对照组) watched a 10-minute clip (电源片段) of the Seinfeld television show.
"We found that short-term social interaction lasting for just 10 minutes improved participants’ intellectual performance as much as engaging in so-called ’intellectual’ activities for the same amount of time," Ybarra said.
The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin.

It is obvious that doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients about it?
The results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often don’t know what to say.
“So while doctors may tell patients they are overweight, the conversation often ends there,” said Christine C. Ferguson, director of the Stop Obesity Alliance. “Patients are not told about the possibility of diabetes (糖尿病),” she said. “And doctors don’t feel they have good information to give. They felt that they didn’t have adequate tools to address this problem.
The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most overweight patients don’t even know that they’re too heavy. Only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight.
Of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. In fact most have tried to lose weight and may have been successful in the past—and many are still trying, the survey found. And many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesity­related diseases like hypertension and diabetes.
Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn. , which ranks the 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. “If you’re to be successful with helping your patients lose weight, you have to talk to them at actually every visit about their progress, and find something to encourage them and coach them,” he said.
He acknowledged that many doctors tend to be not optimistic.
“Part of this is that there’s this common belief, and doctors are burdened by it, too, that overweight people are weak-willed and just don’t have any willpower and are self­indulgent and all that business,” he said. “If you think that way, you’re not going to spend time having a productive conversation.”
小题1:What is the Stop Obesity Alliance most probably in Paragraph 3?
A．An organization of doctors suffering from obesity.
B．An organization of patients suffering from obesity.
C．A research group that conducts special surveys about overweight people.
D．A research group dealing with doctor-patient relationship.
小题2:How many of the patients surveyed have been advised by their doctors to lose weight?

Paragraph 1
Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds. (2) citrus(柑桔) fruits and tomatoes; (3) potatoes and other fruits and vegetables; (4) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or cereal(谷类), rice is also in this kind of food; (7) butter, or something like butter.
Paragraph 2                                                                 
People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether foods are eaten raw or cooked, canned or frozen. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day.
Paragraph 3

Ever since news of widespread food recalls caused by a carcinogenic dye（颜料） broke, there has been confusion over possible links to the country of the same name, but Sudan officials say there is no connection whatever.
Sudan1 is a red industrial dye that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003.
Since the ban was put in place, EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled.
Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the dye’s name.
Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.
　　"We want to keep an eye on every detail and avoid any misunderstanding there," she said. "Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country. But they told us there was no relationship."
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week.
　"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said. "People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out."
Sudan dyes, which include Sudan1 to 4, are red dyes used for colouring solvents（溶剂）, oils, waxes, petrol, and shoe and floor polishes. They are classified as carcinogens by the International Agency for Research on Cancer.
小题1:What does the underlined word mean in paragraph one?
A．Causing cancer.B．Having side effect.C．Containing poison.D．Poisonous.
小题2:How did the Sudan1 get its name?
A．The dye is often produced in Sudan.
B．The dye has something to do with the country named Sudan.
C．Nobody is sure of the origin of the name.
D．Many foods produced in Sudan contain the dye.
小题3:We can infer from the passage that        .
A．the Sudan government is paying much attention to the food safety
B．Sudan1 is often used to be added to the food
C．people didn’t realize the danger of Sudan1 until 2003
D．many food shops will be closed down
小题4: Which of the following is the best title?
A．Keep away from Sudan1
B．No Sudan1 dye links to the country
C．How Sudan1 dye got its name?
D．Pay attention to the food safety
Choose the yum(美味的东西) and risk the yuk（讨厌的东西）?
Scientists have given us a lot of health warnings. The advice from cancer experts for avoiding bowel(肠) cancer is "try to avoid processed(加工过的) meats such as bacon, ham, corned beef and some sausages", and women fearing breast cancer are told "there doesn't seem to be a starting point at which alcohol consumption is safe",
But all these health warnings tend to have little influence on behavior, So who is being unreasonable —the scientists who give us health advice, or the public that just ignores it?
The curious fact is that both might be right. The reasoning behind these health warnings seems to be this: if you do more of something pleasurable (which we shall give the name “yum”) there is a higher risk of something bad (which we shall give the name “yuk”)occurring, so you should avoid yum.
But when presented with this argument you might ask two questions.
First, maybe the pleasure of yum makes the risk worth taking, especially if yuk might occur a long time in the future? Second, maybe there are other benefits of yum that could cancel out the risks of the particular yuk that has been identified (确认) ?
So suppose bacon sandwiches are your particular yum: research shows that 50g per day — that is a great greasy sandwich — increases your risk of bowel cancer by 20%.
But this means that out of every 100 people who stuffed down that big bacon sandwich every day of their lives, the number of bowel cancers would rise from five to six.
In addition, if a middle-aged woman gave up alcohol, it might reduce her risk of breast cancer, but could increase risk of some other cancers as well as heart disease.
So we need to look at the whole picture before trying to get people to change what they do, since everything has benefit and harms — just think of the joggers(慢跑者) who get knocked down by cars — and people need to be able to find their own balance.
Therefore, as you reach for your yum, perhaps sometimes pause a moment and realize that you are taking a gamble(赌博) on the yuk occurring, but that it may be a risk worth taking.
小题1:What is the advice given by scientists for avoiding breast cancer?
A．Try to avoid processed meat.B．Try to avoid alcohol.
C．Try to choose the yum.D．Try to risk the yuk.
小题2: What does “this argument” in Paragraph 4 mean?
A．If you choose the yum, you will risk the yuk.
B．If you risk the yuk, you’ll choose the yum.
C．The yum is worth taking, especially if yuk might occur in the future.
D．Other benefits of yum could cancel out the risks of the yuk.
小题3:Why do we need to look at the whole picture before trying to get people to change what they do?
A．Because giving up alcohol might reduce breast cancer.
B．Because people are not able to find their own balance.
C．Because all the things have both sides.
D．Because the advice given by scientists is not true.
小题4:According to the passage, which of the following is correct?
A．People are often influenced by the health warnings.
B．Both the scientists and the public are not reasonable.
C．Alcohol consumption has both benefit and harms.
D．People should avoid yum to reduce the risk of yuk.
You maybe surprised to learn that one of the best steps you can take to protect your health is to step outside and spend some time in the grass, dirt and water．
Our ancestors enjoyed the healing power of nature , and now scientists are starting to catch up．According to research in recent years, just having a view of nature has been shown to improve hospital patients'  recovery and reduce illness rates among office workers．Also, exposure （曝露）to wildlife, horseback riding, hiking, camping and farms can be helpful for a variety of health conditions in adults and children．
Much of this type of research is focusing on children, and in fact an entire movement has quickly developed to connect kids with the healing power of nature．
Obesity （肥胖）．Rates of childhood obesity have grown sharply in recent years, and this is partly because of reduced outdoor activity time．Increasing the time students spend learning about nature, both in and outside the classroom, would help solve this problem．Such lessons are often more attractive for students and often lead them to become more active outside．
Attention deficit hyperactivity disorder （ADHD） （注意力缺失症）．Exposure to ordinary natural settings （环境） in the course of common after-school and weekend activities may be effective in reducing attention deficit symptoms in children．Participation in green activities —such as nature walks—helped ADHD patients from a wide range of backgrounds to stay focused and complete tasks．
Stress．Access to nature, even houseplants, can help children cope with stress．
Depression  and  seasonal  emotional  disorder．Major  depression requires medical treatment, but physical activity, especially outdoors, can help ease symptoms．For your average case of winter blues, experts suggest spending time outside every day and, if possible, taking the family to a sunny vacation spot in mid-winter．
Experts emphasize that you needn' t go to wilderness preserves to enjoy nature' s benefits—simply walking in a city park or growing in a rooftop garden can make a difference．

Nutrition is the study of how the body takes food and uses it. This science provides information about the kinds of food a person must eat to improve and maintain good health. Such knowledge helps him develop and form people habits to his problems of healthful living. People habits of nutrition can be developed by paying attention to: (1) the variety of food included in the diet; (2) the quality of each kind of food eaten. A diet, or the food regularly eaten, must contain all the necessary factors.
Many physicians believe that overweight is one of the greatest dangers to good health. This condition often leads to a shorter life.
