What makes sound? crash boom BAM bang swoosh and splash Sounds are all around us

什么会产生声音？ 哗啦、轰隆、嘭、砰、嗖嗖、哗哗，声音就在我们身边

People, animals, and objects make sounds. Even the weather makes sound. Sounds can be loud or soft. They can be pleasant or unpleasant.

人、动物和物品都会发出声音。 就连天气也会发出声音。 声音可以很响亮，也可以很轻柔。 它们可能悦耳，也可能刺耳。

Animals use sound in many ways. Humans use sound to communicate their thoughts and feelings. Other animals use sound to communicate too. They use sound to defend themselves, attract a mate, or signal a warning.

动物使用声音的方式有很多种。 人类用声音来交流想法和感受。 其他动物也会用声音来交流哦。 它们用声音保护自己、吸引配偶，或者发出警告信号。

Humans have invented many things to make sounds. Drums, bagpipes, and stringed instruments make music. Horns, bells, and sirens sound warnings or call people to events. Alarm clocks signal with music or loud beeps that it is time to get out of bed.

人类发明了很多能发出声音的东西。 鼓、风笛和弦乐器能演奏出音乐。 喇叭、铃铛和警报器用来发出警告，或者召集人们参加活动。 闹钟用音乐或者响亮的蜂鸣声提醒我们该起床啦。

What is sound? Sound is made when an object vibrates or moves back and forth very quickly. People make sound to talk when air vibrates vocal cords in their throats. Different vibrations in the vocal cords make different sounds.

声音是什么呢？ 当物体振动也就是快速来回移动的时候，就会产生声音。 空气振动我们喉咙里的声带，人就能发出声音说话啦。 声带的振动方式不同，发出的声音也不一样。
