为什么擦破的皮会自己长好？

Why does a scraped skin heal by itself?

伤口下面会急忙长出新皮肤，血还会结成痂像小盖子护着伤口。过几天痂掉了，新皮肤就长出来了。
Under the scrape the body quickly grows new skin, and blood forms a scab like a small lid protecting it. After a few days the scab falls off and fresh skin shows.

为什么晒太阳后皮肤会变黑？

Why does skin get darker in the sun?

阳光刺激皮肤制造更多黑色素，像给细胞撑起小阳伞来挡光，皮肤就看起来黑一些。这是身体在自我保护，但仍要涂防晒。
Sunlight makes skin produce more melanin, like raising tiny umbrellas over cells to block light, so skin looks darker. It is self-protection, but sunscreen is still needed.

为什么热的时候会出汗？

Why do we sweat when it is hot?

出汗是身体在给自己降温，汗珠在皮肤上变凉，就把热气带走。出完汗吹吹风，人就舒服凉快了。
Sweating is the body cooling itself; as sweat on the skin turns cool, it carries heat away. After sweating and a bit of breeze, you feel comfortable again.

为什么夏天出门要涂防晒霜？

Why do we put on sunscreen before going out in summer?

防晒霜像一件看不见的小披风，挡住太阳里厉害的光线，保护皮肤不被晒红晒痛。涂了防晒，就能安心在户外玩耍。
Sunscreen is like an invisible cape that blocks the sun's strong light so skin does not turn red or sore. With it on, you can play outside with peace of mind.

为什么天热时特别想喝水？

Why do we feel extra thirsty when it is hot?

天热出汗多，身体里的水跟着流失，大脑就发出口渴信号提醒补水。及时喝水能帮身体保持凉快和正常运转。
In heat we sweat more and lose water, so the brain sends a thirst signal to remind us to drink. Timely water keeps the body cool and working well.

为什么药不能随便吃？

Why shouldn't medicine be taken carelessly?

药是为特定身体问题配的，吃错种类或份量可能伤身体。药要由大人保管和按说明给，小朋友不能自己拿。
Medicine is matched to specific problems, and wrong type or dose can harm the body. Medicine should be kept by adults and given as directed, never taken by children on their own.
