Are you a-teenager{#blank#}1{#/blank#} (absorb) in music? If so, I will give you a warning – the music you love could end up making you deaf. More {#blank#}2{#/blank#}(specific), the way you listen to the music you love could make you deaf.

    The problem is .headphones. In the past, we played music out into the air. Then earmuff-style（耳罩式）headphones {#blank#}3{#/blank#} (invent) and we were able to play music much closer to our eras. Now we have earbuds（耳塞）, which many doctors think are {#blank#}4{#/blank#} (bad) than older headphones because they play music directly into the eras. Also, earbuds are not as good as blocking outside noise, so people{#blank#}5{#/blank#} use them nay turn the volume {#blank#}6{#/blank#} to dangerous levels.

    What's the dangerous level? Well, it {#blank#}7{#/blank#}(depend) on how long you are going to listen to the noise. Very, very loud sounds can be dangerous to your hearing. But the scary {#blank#}8{#/blank#}(true) is that even seemingly “normal” noise can be dangerous {#blank#}9{#/blank#}you listen to it all the time.

    Think for a minute about how long you spend {#blank#}10{#/blank#} (listen) to loud noise with headphones every day. Then do some research. There are resources online telling you what volumes are safe, and for how long.

    Laughter Yoga is a new form of exercise that promotes the use of laughter as a form of physical exercise. It {#blank#}1{#/blank#} (create) in the mid-1990s as a social experiment. Although it came from India and {#blank#}2{#/blank#} (certain) includes some yoga, don't expect it to have much in common with the yoga classes {#blank#}3{#/blank#} (offer) at your local studio or gym. Laughter Yoga attaches {#blank#}4{#/blank#} (much) importance to the former than to the latter.

    The method began in 1995 when Dr. Madan Kataria called on a group of students in a park {#blank#}5{#/blank#} (test) whether introducing regular laughter into people's lives would improve their well-being. Kataria also introduced deep breathing and simple stretches into the exercises.

    Medical research has suggested that laughing is {#blank#}6{#/blank#} good way to reduce stress and help people feel good. Kataria's Laughter Clubs are popping up in response {#blank#}7{#/blank#} people's need to handle {#blank#}8{#/blank#} (press).

    Kataria also offers books and DVDs to people {#blank#}9{#/blank#} don't have access to a local Laughter Club. However, connecting with other humans is a big part of Laughter Yoga's success in {#blank#}10{#/blank#} (help) people feel better and experience more joy.

At first, the locals decided {#blank#}6{#/blank#} (make) zongzi in hopes that it would sink into the river and reach Qu Yuan's body. However, the tradition of wrapping the rice in bamboo {#blank#}7{#/blank#} (leaf) to make zongzi began the following year.
