Four simple ways to stay positive

    Trying to stay positive, both in good times and bad, is a great way to improve your quality of life. Try these four methods on a daily basis.

1）. Don't think a lot about negativity.

    Of course. Staying positive 24 hours a day, seven days a week is a bit difficult. Letting things get to you is normal, and it's actually healthy to cry or express frustrations once in a while.

    It's when those negative moments control your life that your emotional balance is at risk. {#blank#}1{#/blank#} However, don't give that sadness another second in your day.

2）. {#blank#}2{#/blank#}

    What you put into your body directly affects how you feel on the outside. Fill yourself with good, healthy foods like fruits and vegetables and limit snacking. Exercise is equally of great importance. Take a few days out of your week for at least half an hour of activity, and try to stick to it. {#blank#}3{#/blank#}

3）. Be kind to others.

    {#blank#}4{#/blank#} Making someone's day a bit brighter not only puts a smile on his or her face, but also yours as well. Remember to smile and treat each person with pity and respect. Good deeds are contagious（传染的）, and your positive attitude may spread among others.

4）. Take it one day at a time.

    Being positive isn't an instant thing. It's a steady effort that we follow every hour of every day. {#blank#}5{#/blank#} Instead, focus on living at the moment and doing what you can to make each moment better.

A.Eat healthy and stay fit.

B.Take your lunch breaks outside.

C.Don't worry about what the future may bring.

D.Gratefulness helps you appreciate life in bad times.

E.Good feelings come from acts of kindness and selflessness.

F.Take a few minutes to feel sad and accept what happened.

G.Even going outside for a walk and enjoying the sunshine improves your mood.

    Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

    {#blank#}1{#/blank#}I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

    For those who do not particularly enjoy competitive sports—{#blank#}2{#/blank#}—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

    Even after you have found a way for keeping in shape, through sport or gymnastics, {#blank#}3{#/blank#}, because, according to the experts, you must also master the art of complete mental and physical relaxation. {#blank#}4{#/blank#}Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—{#blank#}5{#/blank#}—which were the natural way of life of our forefathers.

A. be active and practise Yoga

B. There are some aspects of our unhealthy lives that we cannot avoid.

C. and it is especially difficult to do so if you are not good at them

D. physical effort on the one hand and relaxation on the other

E. they spent most of the time out of doors

F. you are still only half way to good health

G. It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on.

    The correct way to brush your teeth is to use short, gentle strokes on the teeth, You should pay special attention to the gum (牙龈) line. {#blank#}1{#/blank#}

    Pick the right toothbrush.

    Most dentists say that a soft-upraised toothbrush with a small head is best for removing dirt and rubbish while getting into those hard-to-reach places. {#blank#}2{#/blank#} They have limited skills in their hands and thus they can do a better job at cleaning teeth.

    Pick the right toothpaste.

{#blank#}3{#/blank#} And some are tailored (特定需要) specifically for dental issues such as sensitivity, dirt, holes or gingivitis (齿龈炎). Each person's mouth is different, and it is advisable to talk to your dentist about what toothpaste is best for you.

    {#blank#}4{#/blank#}

    Hold your brush at a 45 degree angle, and use short, circular cleans or back and forth movements on your teeth. Brush the gum line in a pattern that pushes rubbish away from it. {#blank#}5{#/blank#} Make sure that all chewing surfaces are clean, and brush the surface of the tongue too.

    One of the easiest and most pleasing ways to express your creativity (创造力) is by drawing. In addition, drawing can calm you down in many ways. It can help keep you away from negative thoughts and clear your mind. {#blank#}1{#/blank#}

    Draw something that makes you comfortable. Content (内容) does not matter as much as the meaning you connect with whatever you choose to draw. If you find mountains or trees relaxing to be around, try your hand at drawing. You can also draw things like pets or buildings. {#blank#}2{#/blank#} For example, draw a dog's head on a pig's body with a horse's legs and tail.

    Just draw. Experiment on drawing with different color patterns (色型) and emotions. Believe it or not, drawing can help realize physical relaxation by lowering your blood pressure. Color your drawing with bright, exciting colors. Draw patterns. Start with changes of circles, as they're easier to draw. Simply cover a page in a pattern. Keep your subjects smile. Whether you are drawing mountains, humans, or animals, add a face with a smile. {#blank#}3{#/blank#}

    Go somewhere where you feel calm. Choose some quiet places. Turn off your phone, and avoid areas with television or computers. Some private (私人的) places are best, as your drawing will not be forbidden by the presence of others, and you will be less likely to be bothered. Get outside. {#blank#}4{#/blank#}. Drawing outside can also give you ideas of things to draw.

    Have fun. {#blank#}5{#/blank#} Don't worry about the final product. And don't judge your artistic abilities. Lose yourself in the experience of creation! Sitting down to draw for just a few minutes can brighten your feelings. You'll feel energetic and may feel even more open­minded for the rest of the day.

A. Let yourself enjoy the process.

B. Listen to music when you draw.

C. Simply being outside will calm you down.

D. Sure, it's silly but you'll probably smile back.

E. Hang up your work somewhere it will catch your eye.

G. And the enjoyment of drawing can help keep your stresses away.

    Rainbows (彩虹) are one of the most beautiful works that nature creates. {#blank#}1{#/blank#} If you've ever seen one, consider yourself lucky.

    Rainbows can be seen when light passes through raindrops, says Kristin Calhoun, a research scientist studying the conditions of weather.

    When sunlight passes through raindrops, the light bends, as it enters a droplet. As it leaves the droplet, the light separates into different wavelengths (波长). {#blank#}2{#/blank#} The seven colors — red, orange, yellow, green, blue, indigo and violet — bend in seven different directions. Red light, for example, bends in a different way than violet light. {#blank#}3{#/blank#} It also explains why rainbows look like an arc (弧). Sometimes, however, rainbows can actually form a circle that you can see in a plane with the right conditions.

    {#blank#}4{#/blank#} "There is an even better chance when the sun is at a lower level, early or later in the day," Calhoun says. And another key is to face the rain and have your back to the sun.

    {#blank#}5{#/blank#} "Small showers and storms often form in late afternoon in this area," Calhoun says. "These types of showers often produce heavy rain, but remain isolated (孤立的) over the center of the island."

A．There are lots of stories relating to rainbows.

B．Rainbows are created by light through raindrops.

C．And each wavelength appears as a different color.

D．With the conditions just right, Hawaii gets lots of rainbows.

E．The best time to catch a rainbow is when it's sunny and raining.

F．But they can be seen only if you are in the right place at the right time.

G．This is why the person on the ground sees each color at a different location.
