My Heart, written by Rachel Rice, illustrated by Meryl Rainey. Focus Question. Why is your heart an important part of your body?

《我的心脏》，作者：蕾切尔·赖斯，绘者：梅丽尔·雷尼 思考问题 为什么心脏是你身体的重要组成部分？

My doctor checks to see if my heart sounds healthy. She listens to my heart, and I stay quiet and still.

医生会检查我的心脏听起来是否健康。 她听我心跳的时候，我会安安静静、一动不动。

She hears the healthy sound, lub dub, lub dub.

她听到了健康的心跳声：扑通、扑通。

My heart needs to be healthy to move blood around my body. My heart needs to work hard for me, even when I sleep.

我的心脏要保持健康，才能把血液输送到全身各处。 哪怕我在睡觉，我的心脏也一直在为我辛勤工作。

Blood is how my body moves many things it needs, such as oxygen and nutrients. It is also how my body moves around some of its waste.

血液负责运输身体所需的多种物质， 比如氧气和营养。 它也会帮身体运走一部分代谢废物。

My heart doesn't make blood, but it does keep my blood moving. My heart is made mostly of muscle. Each time my heart muscle squeezes, it moves blood.

我的心脏不生产血液， 但它能让血液一直保持流动。 我的心脏主要由肌肉构成。 每次心肌收缩，就会推动血液流动。
