    It is reported that although our genes and environment play an important role, how happy we are largely depends on our choices and activities. The following are just several areas that tend to make a big difference to people's happiness.

    Take a positive attitude

    Positive emotions―like joy, gratitude, satisfaction, inspiration and pride― don't just feel good when we experience them.{#blank#}1{#/blank#} So although we need to be realistic about life's ups and downs, it helps to focus on the good aspects of any situation―the glass half full rather than the glass half empty.

    Accept who you are and what you are

    {#blank#}2{#/blank#} Learning to accept ourselves and being kinder to ourselves when things go wrong will increase our enjoyment of life. It also helps us accept others as they are. Ask a trusted friend or colleague to tell you what they think your real strengths are.{#blank#}3{#/blank#}

{#blank#}4{#/blank#}

    Caring about others is fundamental to our happiness. Helping other people is not only good for them; it's good for us too. It makes us happier and can help to improve our health. Giving also creates stronger connections between people and helps to build a happier society.

    Take part in something bigger

    People who have meaning and purpose in their lives are happier. They also experience less stress, anxiety and depression.{#blank#}5{#/blank#} It might come from doing a job that makes a difference, or spiritual beliefs, or our family. The answers may be different for each of us but they all involve being connected to something bigger than ourselves.

A. Our broader social networks bring a sense of belonging.

B. Nobody is perfect.

C. Give them a call or offer your support.

D. Try to make more use of these.

E. They also help us perform better, and improve our physical health.

F. But where do we find meaning and purpose?

G. Do things for others.

    Get a Thorough Understanding of Oneself

    In all one's life time it is oneself that one spends the most time being with or dealing with. {#blank#}1{#/blank#}

    When you are going upwards in life you tend to overestimate (高估) yourself. It seems that everything you seek for is within your reach. {#blank#}2{#/blank#} It's likely that you think it wise for yourself to stay away from the outer world. Actually, you may keep the following tips in mind.

    Gain a correct view of oneself.

    You may look forward hopefully to the future but be sure not to expect too much, for dreams can never be fully realized. You may be brave to meet challenges but it should be clear to you where to direct your efforts. {#blank#}3{#/blank#}

Self-appreciate.

    Whether you compare yourself to a tall tree or a piece of grass, a high mountain or a small stone, you represent a state of nature. {#blank#}4{#/blank#} If you sincerely admire yourself you'll have a real sense of self-appreciation.

{#blank#}5{#/blank#}

    In time of anger, do yourself a favor by releasing it in a quiet place; in time of sadness, do yourself a favor by sharing it with your friends; in time of tiredness, do yourself a favor by getting a good sleep.

A. It has its own value.

B. Do oneself a favor when it's needed.

C. Do yourself a favor when you meet with the attack of illness.

D. But it is precisely oneself that one has the least understanding of.

E. Especially if it is well within your reach, you are just too blind to see it.

F. When you are going downhill you tend to underestimate yourself for not being qualified.

G. So long as you have a perfect knowledge of yourself, there won't be difficulties you can't overcome.

    It is not as simple as opening the door and hitting the track in winter. There are a few things you can do to ensure you are getting the most out of your run, and, importantly, not doing more harm than good.

    Warm up, cool down

    {#blank#}1{#/blank#}Your muscles need some time to warm up when it's cold, so take it easy when you set off and do a few stretches (伸展) once you're finished.

    Drink water

    You might not feel hot, but that's because sweat evaporates (蒸发) more quickly into the chilly, dry air. So be sure to drink water before, during and after cold-weather workouts. {#blank#}2{#/blank#}A belt bottle conveniently attaches to your waist so you don't have to carry it and can have a drink whenever you feel like it.

    {#blank#}3{#/blank#}

    Running in cotton is a bad idea. Wear thin, breathable layers of synthetic ( 合成的)clothing that help protect you from the wind and snow, but still let out heat and moisture (水分) .Thirty percent of your body heat escapes through your hands and forty percent through your head. Wear a hat, or beanie (无边小便帽) ,and gloves so your circulatory system can distribute warm blood to the rest of your body.{#blank#}4{#/blank#} Run into the wind.

    {#blank#}5{#/blank#}Obviously, it will be an easier passage home with some extra help from Mother Nature. But, more importantly, you won't have the wind in your face for the second half of your run, when you are more likely to be sweating and catch a chill.

A. Dress right.

B. Keep warm.

C. Don't go too fast, too soon.

D. Start and finish in the same way.

E. Don't wait to drink water until you feel thirsty.

F. Head out into the wind and come home with it at your back.

G. On really cold days, wear a mask or scarf over your mouth to protect your face.

    Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.{#blank#}1{#/blank#}

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.

    Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day.{#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right.{#blank#}4{#/blank#} The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

    If Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

    Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. {#blank#}5{#/blank#} “You keep what matters,” Tononi says.

A. We should also try to sleep well the night before.

B. It's as if the brain is preserving its most important memories.

C. That's why students do better in tests if they get a chance to sleep after learning.

D. Similarly, when people go for a few days without sleeping, they get sick.

E. The processes take place to stop our brains becoming loaded with memories.

F. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.

G. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.

    Imagine that you are in a remote village somewhere with no medical clinic.{#blank#}1{#/blank#}Once the doctors get to you, they examine you and take blood samples, but they won't be able to help you until they take the samples back to the hospital to find out what is wrong.{#blank#}2{#/blank#}Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic (诊断的) tool.

    Ozcan's invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, don't have enough training to correctly interpret what they see.{#blank#}3{#/blank#}With Ozcan's mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at a hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes.

    {#blank#}4{#/blank#}His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.

By inventing a medical tool that uses existing technology—mobile phones—Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effectively almost anywhere.{#blank#}5{#/blank#}

A. As a result, they may diagnose illnesses incorrectly.

B. People are trying to reduce the cost of this new medical tool.

C. This tool has become much more popular all around the world.

D. Another reason that Ozcan's invention is important is that it is inexpensive.

E. You become very sick and must wait days until a mobile medical unit arrives to help.

F. Ozcan's simple, cost-effective tool might just save millions of lives around the world.

G. Even though you may only have a simple infection, you might die because of the delay.
