【推荐1】While there are many different methods of fighting with stress, arming your body with mood-improving food is one of the most basic places to start. Try adding the following foods to your diet, and step away from bread and cake.

1. Eggs

Rich in protein, eggs also provide calcium, iron, zinc, selenium, phosphorus, and vitamins A, D, E, and K, making them one of the most nutritional foods around. Drew Ramsey, author of The Happiness Diet, praises nutrient-rich foods for battling stress and notes that eggs are part of his favorite anxiety-reducing breakfast.

2. Fish

Eating fish can have many benefits (好处), including fighting stress. Fish (like sardines, salmon, canned tuna) is rich in omega-3 fatty acids. Studies show omega-3 fatty acids help with depression as well as encouraging more positive social behavior in children.

3. Red peppers, papayas and kiwis

They have more vitamin C than oranges. Many studies point to vitamin C for controlling stress hormones. As Psychology Today reports, “People who have high levels of vitamin C do not show the expected mental and physical signs of stress when faced with serious psychological challenges.”

4. Tea

Drinking black tea may help you recover from stressful events more quickly, notes WebMD. One study looked at people who drank four cups of tea daily for six weeks, compared with people who drank something else. At the end of the study, the tea drinkers reported feeling calmer and had lower levels of cortisol after stressful situations.

5. Dark chocolate

Chocolate can help improve the mood and keep clear thinking. Studies also show dark chocolate can help people feel good and reduce stress. Not to mention, it might make you smarter. Is it just a coincidence (巧合) that the higher a country’s chocolate consumption is, the more Nobel Prize winners it creates? More chocolate, please.

A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fiber, without giving us too much fat and sugar. But why is water important?

The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.

Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems start as a result of dehydration (脱水)-—a lack of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stage of dehydration. In fact, we are advised to drink water before we feel thirsty.

These doctors think that health problems such as headaches, high blood pressure and asthma (哮喘) could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water. There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.

1. From the text, we know water can carry_________.

A．energy and fiber in our bodies	B．fruit, vegetables and fish in our bodies
C．sugar and fat out of our bodies	D．poisons and waste out of our bodies

2. Some doctors think that________.

A．some health problems are caused by a lack of water

B．water is not important for our health

D．people eat too much sugar

3. Lack of water caused people to put on weight too much because_______.

A．they think they are thirsty and eat less	B．they think they are hungry and eat too much
C．water has no calories	D．it makes them thirsty

4. Which of the following isn’t mentioned in the passage?

A．The amount of water a person should drink in a day.

B．Some healthy problems start because of a lack of water.

C．Drinking more water may stop people from overeating.

D．Fruit provides us with energy and fibre.

【推荐3】Around the world, eggs have been a breakfast staple（重要部分）for all good reasons. After all, an egg is a storehouse of vital nutrients, making it an essential part of a healthy diet. And for those of you who are afraid of having this power food because you're worried that it will add to your weight, remember, one egg contains about 80 calories and about five grams of fat. Hence, smart consumption is a far healthier option.

Eggs are a well-known rich source of protein — an important building block of bones, muscles, skin, and blood. The body uses protein to build and repair tissues as well as making other body chemicals. Unfortunately, unlike fat and carbohydrates(碳水化合物), the body does not store protein, and therefore has no reservoir to draw on when it needs a new supply. Thus eggs are the perfect sources and a smart food choice for those who reduce their intake of carbohydrates in a bit to lose extra weight.

Another important nutrient you'll find abundantly in egg white is riboflavin or Vitamin B2. And for all of you wondering what's the benefit of this nutrient, Riboflavin is a water-soluble(水溶性) vitamin which is involved in vital processes in the body and is necessary for normal cell function, growth, and energy production.

The yolk, which many of us avoid out of fear, is actually a very healthy food, if consumed in moderation(适度). Mainly fat, the yolk contains 1.33 gm of cholesterol（胆固醇） per 100 gms and is a rich source of vitamin A, B vitamins, calcium, phosphorous(磷) and iron. Incidentally, the iron found in the yolk is easily digested in the body. According to nutrition experts, one can eat one whole egg every day without harming one's cholesterol and other blood-fat levels. But for those who crave for more eggs, you can reduce fat by having one whole egg and the whites of the rest of the eggs.

1. Eggs are regarded as important in breakfast because__________.

2. When our body is short of protein, we may____________.

A．feel tired and sleepy.

B．feel discomfort in our legs.

C．get tired of eating eggs.

D．be eager for other chemicals.

3. We can infer from the last paragraph that____________.

A．the author suggests we only eat the whites of eggs.

B．eating enough yolk can reduce cholesterol in the body.

C．iron and phosphorous in the yolk are difficult to digest.

D．high blood-fat level can do harm to our health

【推荐2】In recent years, many Americans of both sexes and various ages have become interested in improving their bodies. They have become devoted to physical fitness. The need to exercise has almost become natural with many people who have a strong desire to be more physically fit.

By nature, Americans are enthusiastic and energetic about their hobbies and pastimes. They apply their energy to running. As a result, there are running clubs to join and many books and magazines to read about running.

The desire to be physically fit is explained by a “passion” for good health. The high rate of heart attacks in the 1960s caused an increase on the part of the public in improving the human body. Middle-aged men especially suffered from heart attacks. Thus, they are one group strongly interested in more physical exercise. In fact, many doctors encourage their patients to become more physically active, especially those who have sedentary jobs. It is interesting to note that the rate of heart attacks began to decrease in the 1970s and it is still decreasing. Physical fitness enjoys a favored role in the United States at present. It is a new “love” that Americans have valued very much. Will it last long? Only time will tell--- or until another “new passion” comes along.

1. We can learn from the passage that ________ .

A．people’s interest in physical exercise has something to do with their health condition

B．by nature, Americans are stronger and more energetic than others

C．the love for physical exercise won’t last long in American

D．men have a stronger desire than women to take exercise

2. In recent years, many Americans have become interested in improving their bodies because ________ .

A．there are many running clubs to join

B．they are eager for their hobbies and pastimes

C．they have a strong desire to be more physically fit

D．there are many books and magazines about running

3. According to the passage, the underlined word in the last paragraph “sedentary” means ________.

【推荐3】Nowadays, are you sitting more and more? Take a moment to think about your sitting habits. You’re probably sitting while reading this.     1    Besides, many people still lie on the sofa swiping their phones instead of doing exercise after work. That’s undoubtedly a lot of sitting. The fact is that the amount of time spent sitting has increased over time.     2    

People know sitting too much is unsuitable, and most of us naturally feel a little guilty after a long-time TV watching. But what problems gradually exist when we seat ourselves for nearly eight hours per day? A study on nearly 8000 adults suggests that there’s a direct relationship between the time spent sitting and our risk of early death from any cause.     3    

“Sit less, move more” is what the Heart Foundation encourages us to do.     4    It is like telling people to just “exercise” without telling them how. Exercise guidelines are always more practical. For example, the Centers for Disease Control and Prevention recommends adults do exercise for two hours and 30 minutes every week, plus muscle strengthening exercise two or more days a week. We need similar guidelines for sitting.

    5    One of them is from Diaz’s research team. “It would probably be like this: for every 30 continuous minutes of siting, stand up and move or walk for five minutes at a quick pace,” Diaz, the lead researcher, said, adding that the study has put us a step closer to the satisfying guidelines. But more researches are needed to confirm their approaches.

A．Now it’s time to get up and move around.

B．It is quite usual for you to remain seated in a business meeting.

C．As the total sitting time increases, so does the danger of early death.

D．But the function of this rule is just too simple and abstract to benefit us a lot.

E．The experts suggest that more exercise should be done to reduce sitting time.

F．It is reported that many people have spent more than 6 hours sitting or lying.

G．Various specific and detailed guidelines have been made to inspire people to reduce sitting time.

【推荐1】Food likes and dislikes vary from culture to culture. Canadians are generally considered to be conservative (保守的) in their food tastes, but actually, the ability to enjoy different kinds of foods is highly regarded in Canada. A Canadian family may eat Italian food one night, Chinese food the next, and then Greek or Japanese food. Eating in Canada will provide you a good chance to enjoy various foods and get in touch with different cultures. Canadians often invite people to dinner. It’s customary to arrive on time for a dinner party and to bring along a bottle of wine or a small gift, such as flowers or candy. Food is not brought unless especially asked for by the host. Some meals may include appetizers（开胃菜）, soup or salad before the main course. A typical main course includes meat or fish, potatoes or rice, or one or two vegetables. Dessert is usually served with coffee or tea at the end of the meal.

To show that you enjoy a meal, it is polite to praise the quality of the food. Be sure to accept a second helping if you like the food and are not full. But in some other countries, it is polite to refuse up to three times before accepting a second helping.

【推荐2】Have you ever dreamed of visiting a planet in the Milk Way (银河系)？While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.

European researchers are now conducting hibernation(冬眠) experiments. The study may help them understand whether humans could ever sleep through the years it would take for a spaceflight to distant planets. “If there was an effective technology, it could make deep-space travel a reality,” said Mark Ayre of the European Space Agency last month.

What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state. They have now moved on to small, non-hibernating mammals like rats.

A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex. “It’s like moving from a simple Apple computer to a supercomputer,” said Marco Biggiogera, a hibernation researcher at Italy’s University of Pavia. Just like bears and frogs, the hibernation of human beings would cause a person’s metabolism (新陈代谢) to lower so they would need less energy.

Medical research, however, is just half of a spaceflight hibernation system. There is the challenge of designing a suitable protective shelter(栖身所). Such a shelter would provide the proper environment for hibernation, such as the proper temperature It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.

According to Ayre, the six-person human Outer Planets Exploration Mission to jupiter’s moon (木星的卫星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.
