According to a new study by Israel researchers from University of Haifa, posting blogs to express feelings and emotions is therapeutic for children aged 13-17. Psychology professors Meyran Boniel-Nissim and Azy Barak have found that a teenager writing a publicly-viewed blog on the Internet is more effective for relieving stress rather than keeping a private diary. The study, published in the journal Psychological Services, supports that expressing oneself through writing can be therapeutic.
To conduct the research, Boniel-Nissim and Barak randomly selected Israeli high school students who displayed a certain degree of stress. The teenagers were then divided into six groups. Two groups were asked to post blogs twice a week about their social difficulties, but only one of them was asked to open the blogs for comments. The next set of groups were also asked to blog twice a week to post about whatever was going on in their mind, again with one group allowing comments. The two control groups were asked to keep an old-fashioned private diary.
The researchers then collected the blog posts and diaries to discuss the adolescents’ emotional and social position. From the research, they saw that the greatest improvement in mood was with the bloggers who wrote about their personal troubles and allowed people to interact with their posts. The research also noted that the comments were mostly positive and constructive. Boniel-Nissim and Barak said that the commentators’ interactions helped the bloggers while they were distressed. The conclusive research noted that expressing yourself on the Internet not only let others know what was personally going on with you, but also helped you figure out some things about yourself too.

People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals(间隔)each day.
Low-calorie Diets Do Not Work 
The reason people cannot lose weight by starving themselves is that their metabolism(新陈代谢)will detect any major drop in calories and it will then adjust(调整)itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2, 500 calories per day and not gain any weight.
Low-fat Diets Do Not Work
Many people in today’s society are buying mostly low- fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle.
Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.
【小题1】What is the main reason why people are overweight according to the author?

Research has shown that music has an important effect on one’s body and psyche (心灵). In fact, there is a growing field of health care known as music therapy, which uses music to treat diseases. Even hospitals are beginning to use music therapy. This is not surprising, as music affects the body and mind in many powerful ways.
Research has shown that quick music can make a person feel more alert, while slow music can produce a calm, deep thinking state. Also, research has found that music can change brainwave activity levels. This can help the brain to change speeds more easily on its own as needed, which means that music can bring lasting benefits to your state of mind, even after you’ve stopped listening.
Breathing and heart rates can also be influenced by music. This can mean slower breathing, slower heart rate. This is why music and music therapy can help reduce the damaging effects of long-term stress, greatly promoting (促进) not only relaxation, but health.
Music can also be used to bring about a more positive state of mind by helping to keep worries away. Music has also been found to bring many other benefits, such as lowering blood pressure and reducing the risk of strokes. It is no surprise that so many people are considering music as an important tool to help the body become or stay healthy.
【小题1】What can we infer about music therapy?

●What prevents depression：tea，coffee or hot chocolate?
Women who drink for or more cups of coffee a day are a fifth less likely to become depressed．Drinking two or three cups reduces the risk by 15 percent. This is the result of a study of 51,000 women over ten years, published in the Journal of the American Medicine Association.
One theory is that caffeine reduces the  effect of the chemical adenosine(腺苷) in the brain, which can make us feel sleepy by slowing down nerve cell activity. Some anti-depressants also work by blocking the adenosine receptors. Coffee was found to be far more influential on depression levels than hot chocolate or tea due to the high caffeine content.
●How many eggs can we healthily eat: one a day or two a day?
Neither-eat them freely. We’ve long been warned to stick to two or three eggs a week because of their high cholesterol(胆固醇)content. But according to the Food Standards Agency, there is no recommended limit to how many eggs we can healthily eat, unless you have been told to cut down by your doctor.
There is no evidence that eating eggs raises cholesterol levels, and researchers found that eggs contain less cholesterol than in the past because hens are no longer given bone meal, which was banned in the 1990s after the BSE(疯牛病) cresis.
Research by the British Egg Council found that a medium egg gives you around 100 mg of cholesterol, a third of the 300mg recommended daily limit.

Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule, protecting them from the body—and the body from them—until they can be released at just the right spot. There are lots of ways to trigger (引发) this release, including changing temperature, acidity, and so on. But triggers can come with their own risks—burns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR, 近红外线) on the drug in the capsule.
The idea of using light to liberate the drug in the capsule isn’t new. Researchers around the globe have developed polymers (聚合物) and other materials that begin to break down when they absorb either ultraviolet (UV, 紫外线) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds (化合物) absorb NIR well and go through chemical changes.
That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it separates from the polymer.
So Almutairi and her colleagues reported creating a new material for capsules that’s even better.This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive(易反应的) components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a light-absorbing compound called Bhc. When the Bhcs absorb NIR light, the reactive groups are exposed and break the long polymer into two short chains. Shining additional light continues this breakdown, potentially releasing any drugs in the capsule. What’s more, Almutairi says, Bhc is 10 times better at absorbing NIR than is ONB and is not poisonous to cells.
【小题1】According to the passage, which of the following could be the best trigger?

Eating a diet high in processed food(加工食品)increases the risk of depression，research suggests．What's more，peopie who ate plenty of vegetables，fruit and fish actually had a lower risk of depression，the University College London team found．
Data on diet among 3，500 middle-aged civil servants(公务员)were compared with their emotional state five years later，a British journal reported．They split the participants into two types of diet--those who ate a diet largely based on whole food，which inc!udes lots of fruit， vegetables and fish，and those who ate a mainly processed food diet，such as sweetened desserts，fried food，processed meat，refined grains and high fat dairy products After accounting for factors such as gender，age，education，physical activity，smoking habits and chronic(慢性的) diseases，they found a significant difference in the future depression risk with the different diets．
Those who ate the most wholefood had a 26％ lower risk of future depression than those who ate the least wholefood．By contrast，people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods．
Study author Dr. Archana SinghManoux pointed out there was a chance the finding could be explained by fl lifestyle factor they had not accounted for．
There was a paper showing a Mediterranean diet was associated with a lower risk of depression，but the problem with that is if you live in Britain，the likelihood(可能性)of you eating a Mediterranean diet is not very high．
Dr．Andrew McCulloeh，chief executive of the Mental Health Foundation，said，this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health．
He added people's diets were becoming increasingly unhealthy．The UK population is consuming less nutritious，fresh produce and more saturated(含饱和脂肪酸的)fats and sugars．

Many people think of guys as being carefree when it comes to their appearance. But in fact, a lot of guys spend plenty of time in front of the mirror.    1   .
Body image is a person’s opinions and feelings about his or her own body and physical appearance.     2   . You appreciate your body for its capabilities and accept its imperfections.
So, what can you do to develop a positive body image? Here are some ideas:
Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking, dancing, or even running. Or perhaps you have non-sports skills, like drawing, painting, singing, playing a musical instrument, writing, or acting.      3   .
Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques (体形) don’t just happen.     4   . A healthy habit can be as simple as exercising 20 minutes to one hour three days a week. Working out can also lift your spirits.
Respect your body! Practicing good habits --- regular showering; taking care of your teeth, hair, and skin; wearing clean clothes, and so on --- can help you build a positive body image.
   5     . Your body is just one part of who you are. Your talent for comedy, a quick wit (智慧), and all the other things make you unique. So try not to let small imperfections take over.

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he op­erated on them. He made the monkeys’ blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys’ brains. When the brain’s tempera­ture was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
【小题1】The biggest difficulty in operating on the damaged brain is that _______.

If you have to miss a meal a day, which meal will cause you fewest health problems if you don’t eat it? If you have to make a decision of this type, most people (especially very busy people) will choose to skip breakfast.
However, many experts in the field of health consider breakfast ( the meal which “break” you “fast” ) to be the most important t meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients (营养) we need to begin our working day with vigor(活力) and stay hopeful with good honor. However, many people skip breakfast or substitute a cup of coffee for a well balanced meal. What happens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people. Participants included both males and females who ranged in age from 12 to 83. The results showed that if a person eats an adequate breakfast, he or she will work more efficiently and more productively than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental(脑力的) activities. The study showed that if school-children eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate (集中)on their lessons for a longer period of time than if their breakfast is inadequate.
The study also showed that contrary to what people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you want to lose weight, skipping breakfast will not help you. You will likely lose more weight if you decrease your other meals.
【小题1】According to experts, breakfast is the most important meal of the day because _____.
