Is Fresh Air Really Good for You?

    We all grew up hearing people tell us to "go out and get some fresh air." {#blank#}1{#/blank#} According to recent studies, the answer is a big YES, if the air quality in your camping area is good.

    {#blank#}2{#/blank#} If the air you're breathing is clean-which it would be if you're away from the smog of cities-then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉)and your brain.

    Recently, people have begun studying the connection between the natural world and healing(治愈). {#blank#}3{#/blank#} In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood(情绪).Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. {#blank#}4{#/blank#} It gives us a great feeling of peace.

    {#blank#}5{#/blank#}While the sun's rays can age and harm our skin, they also give is beneficial Vitamin D. To make sure you get enough Vitamin D—but still protect your skin— put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that's plenty of time for your skin to absorb a day's worth of Vitamin D.

A. Fresh air cleans our lungs.

B. So what are you waiting for?

C. Being in nature refreshes us.

D. Another side benefit of getting fresh air is sunlight.

E. But is fresh air really as good for you as your mother always said?

F. Just as importantly, we tend to associate air with health care.

G. All across the country, recovery centers have begun building Healing Gardens.

    It's important to learn how we can protect the environment. Here are 5R rules for us.

    Reduce. If you want to reduce waste, you should use things more wisely.{#blank#}1{#/blank#} If everyone uses paper carelessly, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the amount of waste we produce.

    Reuse. You should always think of reusing things before throwing them out. For example,{#blank#}2{#/blank#}. In a family, you may pass on such clothes to younger brothers or sisters.

    Recycle. Bottles, cans and paper can easily be recycled. By doing so we can save lots of time and money. For example,{#blank#}3{#/blank#}. The metal can be used to make new coke cans.

    Recover.{#blank#}4{#/blank#}. You have two choices: one is to throw the apples away, the second is to throw the rotten ones and keep the good ones. In this way, you are recovering the eatable parts of food.

    Repair. If one of the legs of your table is broken, you should repair it. If you want to buy something newer and better, it is better for you to sell the old table, or {#blank#}5{#/blank#}Learn the rules to protect our environment. Let's try our best to make the earth cleaner and more beautiful.

A. give the clothes you do not use or the ones which are too small to the poor.

B. coke cans are sent to a factory, where they are smashed flat and melted.

C. A large number of trees are being cut down to make paper.

D. Trees are planted every year.

E. give it to people who can use it after repairing it.

F. don't throw it away if you can use it.

G. When you buy a box of apples, there may be a few rotten ones.

Everyone knows that early to bed and early to rise is good for your health.{#blank#}1{#/blank#}It takes a lot of willpower to get out of bed early on a cold winter's day. For this, we specially recommend a "painless early rise" guideline.

{#blank#}2{#/blank#}The secret to becoming a morning person is exposure to natural light. Jennifer Martin, president of the board of directors for the American Academy of Sleep Medicine, agrees with it firstly. That's because natural light holds back melatonin, a chemical that plays an important role in our bodies. "The sun is the driver of our internal clock," she says.

Ease in gradually. For some people like those who need to drive long distances, those first few days of being tired from switching to a new schedule aren't safe.{#blank#}3{#/blank#}"What I'll suggest to people is to shift half an hour, wait a few days, shift another halt an hour, wait a few days, and then shift another half an hour," she says.

Hold on — even on weekends.{#blank#}4{#/blank#}. Decide what time you're going to wake up every day. And stick to it without exception.

Plan something to look forward to. To force you out of bed,{#blank#}5{#/blank#}. You're not worrying if you think of that. "Now is the time to go to buy your favourite coffee or pick up some cakes to have when your alarm goes off at 5 a.m.," she says.

A. Adjust yourself to the schedule at night.

B. Seek out as much natural light as possible.

C. Becoming a morning person is a seven-day-a-week job.

D. But the reality is that getting up late is the norm for many of us.

E. In that case, Martin recommends gradually easing into the early-bird life.

F. Martin suggests treating yourself to something special you can enjoy first.

G. You should cut back on how much exposure to bright light you're getting.
