BEIJING, Jan. 11(Xinhuanet)-- Sleeping a little bit longer a day might help fight against obesity（肥胖）, a recent study shows. The research-- published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research-- after comparing people of normal weight- a body mass index of less than 25- with those who were overweight or obese , found that sleeping for an extra 20 minutes each night could offer a pain-free way to lose weight.
Insufficient sleep is linked with changes in hormone levels that may stimulate（刺激）appetite. A series of studies in recent months have shown that the less people sleep, the heavier they tend to be.
American researcher Robert Vorona from Eastern Virginia Medical School in Norfolk and colleagues have now examined the relationship between people's self-reported sleep time per 24 hours and their body mass index(BMI). They found that total sleep time and BMI were inversely correlated was total sleep time decreased, BMI increased, except in the severely obese group." Americans experience insufficient sleep and corpulent bodies. Clinicians are aware of the burden of obesity on patients," the study said. "Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index," it added. "We warn that this study does not establish a cause-and-effect relationship between restricted sleep and obesity (but) investigations demonstrating success in weight loss via extensions of sleep would help greatly to establish such a relationship."
In November 2004, researchers from Columbia University in New York City, New York demonstrated a clear link between the risk of being obese and hours of nightly sleep, finding that people aged 32 to 59 who slept four hours or less per night were 73% more likely to be obese than people who slept between seven and nine hours per night.The research, which was published in the Archives of Internal Medicine, found that____________.

When I was in the seventh grade, I was a candy striper (义工) at a local hospital in my town. I volunteered(自愿做) about 30 to 40 hours a week during the summer.
Most of the time I spent there was with Mr. Gillespie. He never had any visitors, and nobody seemed to care about his condition. I spent many days there holding his hand and talking to him, helping with anything that needed to be done. He became a close friend of mine, even though he responded with only an occasional squeeze (紧握) of my hand. Mr. Gillespie was in a coma (昏迷).
I left for a week for a vacation with my parents, and when I came back, Mr. Gillespie was gone. I didn’t have the courage to ask any of the nurses where he was, for fear they might tell me he had died. So with many questions unanswered, I continued to volunteer there through my eighth-grade year.
Several years later, when I was a junior in high school, I was at the gas station when I noticed a familiar face. When I realized who it was, my eyes filled with tears. He was alive! I got up the nerve to ask him if he was Mr. Gillespie, and if he had been in a coma about five years ago. With an uncertain look on his face, he replied yes. I explained how I knew him, and that I had spent many hours talking to him in the hospital. His eyes welled up with tears, and he gave me the warmest hug I had ever received.
He began to tell me how, as he lay there comatose (昏睡的), he could hear me talking to him and could feel me holding his hand the whole time. He thought it was an angel(天使), who was there with him. Mr. Gillespie firmly believed that it was my voice and touch that had kept him alive. Then he told me about his life. We exchanged a hug, said our good-byes and went our separate ways.
Although I haven’t seen him since, he fills my heart with joy every day. I know that I made a difference between his life and his death. As importantly, he has made a great difference in my life. I will never forget him and what he did for me: He made me an angel. When the author volunteered at a local hospital, she .

Are you having too much salt? You might not think so, but people in China eat on average (平均) about 12 grams of salt each day, that is much higher than the 6 grams suggested by the World Health Organization. You could be eating too much without realizing it, because about 75% of the salt we eat is already in the food we buy, such as bread, sauces, soups and sausages.
What problems can eating too much salt cause? To answer that question, first let’s take a look at what salt is.
Salt is a chemical compound. It is made of sodium (钠) and chloride (氯化物). Salt is used to keep and flavor foods. A small amount of salt is important for good health because our bodies need sodium and chloride to work.
But past studies have found that people who eat more salt than they need tend to have high blood pressure. Eating too much salt has also been connected with other conditions, such as heart and kidney (肾) problems.
If you want to cut down on salt, the good news is, there are plenty of simple things to do. Here are some tips:
*Cut back on high salt foods.
Most foods contain some salt. But some foods such as cheese, bacon, pickles (泡菜), smoked fish and chips are almost always high in salt because of the way they are made. You can still enjoy them, but try to have these in smaller amounts, or eat them less often.
*Choose reduced salt bread and breakfast cereals.
Bread and breakfast cereals (谷物) are major source of salt in the diet, not that they’re necessarily high in salt but because we eat a lot of them. For these foods, there can be a really big difference between different types and brands. So next time you’re shopping, take the time to compare the salt levels on a few similar products. And always try to choose the ones lower in salt.
*Avoid adding salt to cooking and at table. Instead, you could use herbs and spices (香料) such as garlic (大蒜) and lemon juice to add flavor to meals.Many people in China don’t realize they are eating too much salt because ______.
| A．salty food tasted better than reduced salt food |
| B．they do not calculate the amount of salt they eat |
| C．about 3/4 of the salt we eat is already in the food we buy |
| D．few people experience problems from eating too much salt |
For a healthier life, the author’s suggestion is to ________.
| A．cut back on food with less salt |
| B．eat less heavily salted food |
| C．eat as much reduced salt bread as is wanted |
| D．stop eating bread and breakfast cereals |
What is the purpose of the article?
| A．To warn people of food containing too much salt. |
| B．To inform people of the right amount of salt taken each day. |
| C．To advise people to be careful about the amount of salt they eat. |
| D．To promote (促进) the right way to make reduced salt food. |
How to Study Smarter, Not Harder
Here are some of our favorite study tips that will help any student study smarter, not harder:
Recite As You Study
Reciting—saying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening. It will also help you to notice your mistakes and the topics you have trouble understanding.
Take Fuller Notes
Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words.
Study the Middle
The best time to review is soon after you’ve learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review.
Sleep On It
Study before going to bed, unless you are very tired. It’s easier to remember material you’ve just learned after sleeping than after an equal period of daytime activity, because your brain continues to think even after you’ve fallen asleep.
Combine Memory and Understanding
There are two ways to remember: by memorizing and by understanding. Multiplication tables(乘法表), telephone numbers, and math formulas(公式)are better learned by memorizing(记忆). Ideas are best learned by understanding.
The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again.You can notice your mistakes by _______.
| A．saying things out aloud | B．taking notes |
| C．studying the middle | D．sleeping on it |
When taking notes, you should _______ to better help you with reading.
| A．underline important notes |
| B．write notes in your own words |
| C．take down every detail |
| D．write as quickly as possible |
The writer advises you to _______ as it is easier for you to remember material.
| A．study after a period of activity |
| B．do some exercise after studying |
| C．study as soon as you get up |
| D．study before going to sleep |
Which of the following is NOT helpful for your understanding?
| A．Thinking about an idea in different ways. |
| B．Relating ideas and concepts with what you already know. |
| C．Reading from the beginning to the end without stop. |
| D．Going back to what first made you confused and start again. |
Why is pink or purple a color for girls and blue or brown for boys?
The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils (灾祸).
People’s choice of colors is also influenced by their bodies’ reactions (反应) toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomachaches.
Red can cause a person’s blood pressure to rise and increase people’s appetites (食欲). Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person’s eye.
Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.
The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.Muslims regard green as a symbol of heaven mainly because of their .
| A．cultural values | B．commercial purposes |

“A very disruptive(调皮捣蛋的) six-year-old child kicked my legs and clawed at my hand,” said one teacher. “ I broke up a fight and was kicked between my legs,” said another. Many people have heard stories like this. But the situation is more worrying still and it involves parents.
Every child, regardless of the circumstances into which they are born, has the right to achieve their potential, regardless of their parents’ wealth and class. And we recognize that, as a nation, it is a long way to achieve this goal. But with rights come responsibilities and what worries people is that we are in danger of ignoring the latter.
Far too many children are behaving badly at school, even to the point of being violent to staff. This is terrible enough, but it is hard to be surprised since many children are just mirroring the behaviour of their parents.
My members tell me that parents also come into school often and threaten staff and some staff have been attacked by a pupil’s parents. One father encouraged his child to start a fight on the playground before school started. A primary teacher reported that a parent shouted at him. We need to have a serious and sensible debate about the roles and responsibilities of parents and the support that they can reasonably expect of schools and teachers.
Children will not learn how to behave as social beings if they are stuck in front of the TV for hours every day. They need their parents to show an interest in them and to spend time with them, helping them to play with their peers(同龄人) and to learn the rules of social behavior.
Children are now arriving at school socially undeveloped, increasingly unable to dress themselves, unable to use the toilet properly, unable to hold a knife and fork and unused to eating at a table, Mary Bousted, general secretary of the Association of Teachers and Lecturers, writes in today’s Observer. Instead of taking responsibility themselves, too many parents expect teachers to control their children’s behavior and wellbeing, she adds. Bousted says one mother blamed staff when she discovered that her 16-year-old son was smoking.
We are in danger of becoming a nation of families living separate lives under one roof. The bedroom, once a place to sleep, has become the living space for the young. Spending hours in front of computer screens, on social networking sites or being immersed(沉迷于) in computer games, children and young people spend little time with their parents. Parents are unable to monitor just what their children are watching.
Schools cannot right the wrongs of society and teachers cannot become substitute parents. Both parties need to work together. Parents must be helped and given confidence to take bake control. They are responsible for setting boundaries for their children’s behaviour and sticking to those boundaries. They are responsible for setting a good example to their children and for devoting that most precious of resource------time------- so that children come to school ready and willing to learn.In the opinion of the writer, what problem do people ignore?
| A．The violence in the school. |
| B．The study pressure of students. |
| C．The responsibilities of the students. |
| D．The right to achieve students’ potential. |
The underlined part in Paragraph 7 means _____.
| A．parents care little about children’s life at home |
| B．parents and children live in their separate rooms |
| C．children don’t live with their parents in the same house |
| D．children live a different life from that of parents at home |
The author’s attitude to the behaviour of parents may be ______.
| A．dissatisfied | B．indifferent | C．understanding | D．tolerant |
From the last paragraph, we can infer that ______.
| A．teachers have no responsibility for playing the role of parents |
| B．schools can’t correct the wrongs that society does to teachers |
| C．students are responsible for making themselves known in society |
| D．parents should spend time with children to make them ready to learn |
