Naturally regulate your sleep-wake cycle

Melatonin(褪黑激素) is a naturally occurring hormone(激素) that helps regulate your sleep-wake cycle. Melatonin production is controlled by light exposure. Your brain should produce more in the evening, when it's dark, to make you sleepy, and less during the day when it's light and you want to stay awake. However, many aspects of modern life can disturb your body's natural production of melatonin and your sleep-wake cycle.

Spending long days in an office away from natural light, for example, can impact your daytime wakefulness and make your brain sleepy. Then bright lights at night—especially from hours spent in front of the TV or computer screen—can hold back your body's production of melatonin and make it harder to sleep, However, there are ways for you to naturally regulate your sleep-wake cycle, improve your body's production of melatonin, and keep your brain on a

healthy schedule.

              Increase light exposure during the day

☆Remove your sunglasses in the morning and let light onto your face.

☆Spend more time outside during daylight. Try to take your work breaks outside in sun light, exercise outside, or walk your dog during the day instead of at night.

☆Let as much light into your home/workspace as possible. Keep curtains and blinds open during the day, move your desk closer to the window.

☆If necessary, use a light treatment box. A light treatment box can create sunshine and can  be especially useful during short winter days when there's limited daylight.

            Improve melatonin production at night

☆Turn off your television and computer. Many people use the television to fall asleep or relax at the end of the day. Not only does the light hold back melatonin production, but television can actually excite the mind, rather than relaxing it. Try listening to music or audio books, or practicing relaxation exercises. If your favorite TV show is on late at night, record it for viewing earlier in the day.

☆Don't read from a backlit device at night (such as an iPad). If you use a portable electronic device to read, use an eReader that is not backlit, i. e. one that requires an additional light source such as a bedside lamp.

☆Change your light bulbs. Avoid bright lights before bed, use low-wattage bulbs instead.

☆When it's time to sleep, make sure the room is dark. The darker it is, the better you'll sleep. Cover electrical displays, use heavy curtains or shades to block light from windows, or try an eye mask to cover your eyes.

☆ Use a flashlight to go to the bathroom at night. As long as it's safe to do so, keep the light to a minimum so it will be easier to go back to sleep.

Moving in with a boyfriend causes women to eat more unhealthily and put on weight. But the opposite is true for men, whose long-term health benefits when they move in with a female partner.

Dieticians at Newcastle University said both partners try to please one another, and so change their dietary habits to suit their other half.

It leads men to eat more light meals, such as salads, fruit and vegetables, while women choose to make creamier, heavier dishes like curry or rich pasta sauces, which may please their partner.

Women still have the strongest long-term influence over the couple’s diet and lifestyle, as they still have the traditional role of shopper and cook in most households.

The report, by Newcastle University’s Human Nutrition Research Centre, reviewed the finding of a variety of research projects from the UK, North America and Australia, which looked at the eating and lifestyle habits of couples.

The research shows that women are more likely to put on weight and increase their consumption of foods high in fat and sugar when they move in with their partner.

Women also use food as a comfort when dealing with emotional stress and have been found to gain weight when a relationship ends, while the same finding has not been observed in men.

Many couples reported food as being central to their partnership, and eating together in the evening was particularly important to many.

Report author and registered dietician Dr. Amelia Lake said, “The research has shown that your partner is a strong influence on lifestyle and people who are trying to live healthier lives should take this factor into consideration.”

In Canada and the United States, there is a new group of children called “satellite kids”, who live in one place but whose parents live in another place.

Asians are immigrating to Canada and the United States in larger numbers than ever before. Most Asians immigrate because they believe that they can give their children a better education in the West. In Asia, especially in China, Japan, and Korea, it is difficult to go to university. Students must first pass the strict national examination. However, in Canada and the United States, it is easy to go to university and anyone who wants to go can go. As a result, Asian parents decide to leave their countries so that their children can go to university.

The problem is that when Asians arrive, they discover that finding a job and making money are more difficult in the West than in the East. Also, they find that they are very lonely, and that they miss their homes. Because of these two reasons, most Asian parents decide to go back to work while their children study in the West. Therefore, these children become “satellite kids”, and most of their parents do not know how sad it is to be a “satellite kid”.

Only until now are Canadians and Americans discovering the “satellite kid” problem. Because these children do not speak English and because their parents are not there to take care of them, they are often absent from school. To be a “satellite kid” means to grow up in a country where you know you are different and where you cannot make friends because you do not speak English well. Also, it means to grow up lonely, because your parents are elsewhere. What these “satellite kids” will probably say to their parents is that it’s better to have parents around than to have a university education.

1.Some Asian parents send their kids abroad because _______.

A．all foreign universities are better than the ones in their own countries

B．they hope their children may easily find a job there

C．the kids may not be accepted by universities in their own countries

D．the kids want to improve their English and make foreign friends

2.“Satellite kids” refer to Asian kids ________.

A．with university education                 B．speaking no English

C．without parents                         D．living abroad alone

3.What is the main idea of the passage?

A．Parents want better education for their kids.

B．Kids in foreign countries alone are badly in need of care from family.

C．Parents feel lonely and miss their families.

D．Canadians and Americans begin to notice the “satellite kids” problem.

Are you an optimist? Do you look at your glass and see it as half full? Do you believe that every cloud has a silver lining and that generally things turn out for the best? Do you believe that if something is meant to be, it will be? If you reply “yes” to all of these questions, then you are an optimist. You probably are enthusiastic, cheerful and outgoing. You may well be successful atwork and in love.

But you may be misguided because things don’t turn out for the best. You may believe that when one door closes another one opens (for example，you may fail to obtain a new job，another chance will come around soon), Wrong. When one door closes, another door slams in your face. That's bitter reality.

Now a book has been published which confirms what we pessimists(悲观者）have suspected all along. It's called The Positive Power of Defensive Pessimism. Its author argues that defensive pessimism can lead to positive results. Defensive pessimism is a strategy used to manage fear, anxiety and worry. Defensive pessimists prepare for things by setting low outcomes for themselves. They carefully consider everything that may go wrong and plan for ways to handle these problems. And this gives them a sense of control. Lawrence Sanno, a psychology professor, says, “What’s interesting about defensive pessimists is that they tend to be very successful people, so their low opinion of the situation’s outcomes is not realistic. They use it to motivate themselves to perform better. ”

So far, so good. This is not rocket science. Defensive pessimists prepare carefully and consider what might go wrong, whether at work, on a date or even in a sports game. It makes sense to have a back-up plan. There are many sayings in English urging caution. For example, “Don’t put all your eggs in one basket,” and “ Don’t count your chickens until they hatch. “ To have a confident and optimistic approach to life’s problems is good. But listen to what Woody Alien，the American comedian says, ”Confidence is what you have before you understand the problem.”

There are pros and cons to being an optimist and a pessimist. Don’t feel bad if you see the glass half empty. You are a realist. But lighten up and hook up with someone who sees the same glass half full.

1.What is the passage mainly about?

A．A book that has recently been published.

B．The dangers of being too optimistic.

C．How to become successful in life.

D．The benefits of defensive pessimism.

2.The underlined sentence “This is not rocket science” in paragraph 4 means     .

A．it is quite simple to understand             B．there is no real proof

C．it’s not a dangerous thing to do            D．the cost is not so high

3.The writer would probably describe himself as          .

A．an optimist        B．a defeatist         C．a realist           D．a scientist

4.Which of the following English expressions would a defensive pessimist believe?

A．“Every cloud has a silver lining.”           B．“Don’t put all your eggs in one basket.”

C．“Whatever will be, will be.”              D．“The glass is half full not half empty.”

Inventors are always looking for ways to make our lives easier, greener and a whole lot more fun. Take a look at the following breakthroughs in science and technology. What in the world will inventors dream up next?
