📖 Sounds All Around

Hi, my name is Annie and I am going to tell you about this book called: Sounds all around. First, did you even know that when you talk, the sound doesn't start in your mouth? Instead, it starts in your throat! Feel your throat when you talk or when you sing. Your fingertips tingle because of your vocal cords. They shake back and forth very fast. This is called a vibration. Now don't talk and sing, then feel your throat. Your vocal cords are still because there are no sounds, and therefore there are zero vibrations! Sounds play very important parts in our lives. Now, did you know you can measure sounds? How soft or loud you whisper and YELL is measured in decibels. For example, whispering is about 30 decibels. Talking is about 60 decibels. Yelling is about 85 decibels. Sounds are all around us. Just open your ears and listen! I recommend this book to people who enjoy learning sounds.

大家好,我叫Annie,今天我要给大家介绍一本书,叫《声音无处不在》。首先,你知道吗?当你说话的时候,声音其实不是从嘴巴开始的,而是从喉咙开始的!当你说话或唱歌时,可以摸一摸喉咙,你的指尖会感觉到轻微的震动,这是因为你的声带在快速地上下振动。这种现象叫做"振动"。现在你可以试试不说话、不唱歌,然后再摸喉咙,你会发现声带是静止的,因为没有声音,所以也就没有振动!声音在我们的生活中非常重要。你知道吗?声音的大小可以用"分贝(decibels)"来测量。比如,耳语大约是30分贝,说话大约是60分贝,大喊大约是85分贝。声音无处不在,只要你打开耳朵仔细听,就能发现很多有趣的声音!我推荐这本书给所有喜欢了解声音的人。
