    I was diagnosed with allergies (过敏反应) when I was a little kid. Other than family, no one truly knows I have allergies, although I have to tell people it's allergies when my eyes start to tear up. {#blank#}1{#/blank#} Sometimes my friends just tease in a friendly way.

    {#blank#}2{#/blank#}I look like a normal kid. I don't mind telling people about my allergies—after all, it's normal to have them. Having allergies hasn't affected my self-confidence.

    {#blank#}3{#/blank#}For example, I am a big traveler and I would enjoy going to see the cherry blossoms in Washington, D. C. But when I come anywhere within a 10-foot range of cherry blossoms it feels like I lose almost all my senses! Even though it's only temporary, I still feel miserable.

    My allergies haven't stopped me from traveling when I can, though. My class trip was to Williamsburg in Virginia. At first it was supposed to be during cherry blossom time, and that had me worried. {#blank#}4{#/blank#}

    I've had to rethink some of my dreams, too. Since I'm allergic to animals with fur, I may need to adjust my hopes of being a veterinarian (兽医) or working in an agricultural-science department. {#blank#}5{#/blank#}

    Now I have learned to deal with my allergies and even see the good side sometimes. Having allergies has taught me not to be prejudiced about people's health conditions.

G. Sure, my allergies have held me back from doing some of the things that I love to do.

                                                                      Little－known facts about germs

    Germs are everywhere and in so many forms.{#blank#}1{#/blank#} There are some steps you can take to help prevent the spread of germs in your personal space.

    Computer keyboards can have more germs than a public toilet.Keys and spaces on a keyboard are main breeding grounds for bacterial and viral growth.{#blank#}2{#/blank#} Clean your keyboard regularly with specialized wipes for electronics，and remove dust with an air duster.

    {#blank#}3{#/blank#} While it seems to make sense that covering your toothbrush would protect，the opposite is the case.With a cover on your brush，a more humid environment is created and more likely to encourage growth of germs.Wash your toothbrush when done，and allow it to air dry.Make sure you store it away from the toilet.

    Hand sanitizer(洗手液) does not always replace soap and water washing.Hand sanitizer is great when you're not near a sink，and need to clean your hands.But given the choice of a spritz of sanitizer or good old soap and water，choose the soap and water route.{#blank#}4{#/blank#}  Lather up and scrub hard for at least 20 seconds，and wash between your fingers and the back of your hands.Don't skimp with the hand sanitizer either—cover the same hand areas as for soap and water.

    {#blank#}5{#/blank#} If you freeze foods that you suspect might be spoiled，freezing them will not kill the germs already in the food.Freezing prevents further bacterial growth，but when you thaw it out，the bacteria continue to increase and pollute your food.

    How Fit Are Young Teens?

    How often do you exercise? A new study finds that most kids ages 12 to 15 aren't getting enough physical activity.{#blank#}1{#/blank#}

    U.S. fitness guidelines recommend (推荐) an hour or more of physical activity every day. According to the study, only 1 in 4 U.S. kids meet the recommendation. Few kids in the survey met the guidelines for physical activity that raises the heart rate and makes you breathe harder. However, most of those kids said they did at least an hour of exercise at that level during the previous week.{#blank#}2{#/blank#}

    The study found fat teens were less active than normal-weight girls and boys. Overweight girls were slightly less active than normal-weight girls.{#blank#}3{#/blank#}

     “There's always room for improvement,” said health expert Tala.{#blank#}4{#/blank#}She also said the results provide useful information to help with fitness campaigns such as Let's Move, which was launched by First Lady Michelle Obama. To inspire kids to eat right and get in shape, the First Lady visits schools and holds exercise events. She also calls on schools to offer regular gym classes.

    The research suggests kids who get physical education may get better grades.{#blank#}5{#/blank#}

A. It's concerning.

B. She is an expert on children's health.

C. She was the lead author of the study.

D. The results are based on about 800 kids.

E. Schools should give kids more time for physical activity.

F. But levels were similar among overweight and normal-weight boys.

G. Overall, about 25% said they got an hour of that kind of difficult exercise every day.

    Lemon water is pretty popular. It's offered as a free upgrade to regular water at pretty many restaurants.{#blank#}1{#/blank#}, others are devotees of the possible health benefits. Here's what may happen if you take up the lemon water habit.

    Easier weight loss

    Studies in mice indicate that the antioxidants(抗氧化剂) in lemons can reduce weight gain despite a high-fat diet. More studies are needed to determine if the results can be applied to humans, but anecdotal evidence is favorable. People who drink lemon water regularly report easier weight loss, though it is unclear if the combination of lemon and water is the fundamental driver.{#blank#}2{#/blank#}.

    Get enough vitamin C

    Vitamin C is an important antioxidant that has a ton of health benefits. It can only be gotten from food as our bodies don't produce it alone. Getting your RDA (Recommended Daily Allowance) of vitamin C can lower the risk of heart disease, stroke, and high blood pressure. Vitamin C is good for your skin and bonds with free radicals (自由电子) that accelerate aging.{#blank#}3{#/blank#}, but they're a great source nevertheless.

    Stabilized moods

    Studies have found that smelling lemon scent reduces stress hormones that regulate mood. Drinking lemon water offers this benefit as well as the vitamins and potassium(钾) in the fruit. {#blank#}4{#/blank#}, and high blood pressure is related to stress, so not getting enough potassium can certainly affect your mood. All in all, lemon water can be a calming drink.

    In the end, drinking water is never a bad call, and there is absolutely no reason not to add lemon to it. Drinking lemon water provides some helpful nutrients and antioxidants. Give it a try!{#blank#}5{#/blank#}.

A. Lemon is a common smell in all manner of cleaning products

B. Potassium plays a huge part in regulating blood pressure

C. There is nothing to lose

D. Lemons aren't the highest in vitamin C

E. While some people drink it simply because of its taste

Lying awake for hours before falling asleep is a common problem. Even if you can finally fall asleep, taking too long to fall asleep can lead to too few hours of sleep altogether. {#blank#}1{#/blank#} So people having trouble falling asleep always wonder how they can sleep well. 

Parents know from experience that gentle music can help babies fall asleep. Science supports this, showing that children of all ages, from babies to elementary school children, sleep better after listening to comfortable music. Fortunately, children aren't the only ones who can benefit from gentle music before bedtime. {#blank#}2{#/blank#}

Listening to music likely improves sleep for more than one reason. Music can promote sleep directly by affecting your physiology (生理机能). {#blank#}3{#/blank#}Besides, it can also promote sleep by becoming a healthy bedtime habit. Many people can't fall asleep quickly because stressful and worrying thoughts keep them awake at night. By listening to music, the mind has something else to focus on. With time, the practice of listening to music at bedtime becomes more effective as the brain positively associates music with sleep. 

{#blank#}4{#/blank#} Studies have looked at many types of music and playlists but there isn't a clear answer about the best music for sleep. What we do know is that researchers have typically used either a self-made playlist or one that has been designed especially with sleep in mind. One of the most important things on how music affects a person's body is their own musical preferences. {#blank#}5{#/blank#} For those who don't want to design their own playlist, online music services have stepped in and usually offer playlists for sleep or relaxation.

A．It can guarantee sufficient sleep.

B．It's natural to wonder about the best type of music for sleep.

C．The quality and quantity of our sleep become poor as we age.

D．Listening to music can reduce your stress and inspire positive feelings.

E．This can have a serious effect on a person's quality of life if it continues.

F．People across age groups report better sleep quality after listening to soft music.

G．Useful personal playlists may include relaxing songs that have helped with sleep in the past.
