英語日記帶翻譯：西瓜皮的學問

清涼可口的西瓜人人都愛吃，我也不例外，但是我一次吃西瓜的`時候，卻有了一個發現。

Everyone likes to eat the cool and delicious watermelon, and I am no exception, but when I eat watermelon once, I have a discovery.

今年夏天，媽媽買了一個大西瓜。這個西瓜又大又圓，活像一個大皮球。我們迫不及待地把它切開，我發現它的皮是綠油油的，裏邊卻紅彤彤的。這是爲什麼呢?於是我放下手中的西瓜，去查《少兒百科全書》，終於我找到了答案。

This summer, my mother bought a big watermelon. The watermelon is big and round, like a big ball. We can't wait to cut it open. I find its skin is green, but it's red inside. Why? So I put down my watermelon and went to look up the Encyclopedia of children, and finally I found the answer.

原來，西瓜的表皮有葉綠素，爲了吸收陽光。但它裏面吸收了陽光，成熟後就變成紅色的了。

Originally, watermelon's epidermis has chlorophyll, in order to absorb sunlight. But it absorbs sunlight and turns red when it matures.

一個普通的西瓜裏都有這麼多的知識!生活中往往隱藏着無窮的知識，等着善於觀察，努力探究的人去發現。

There are so many knowledge in a common watermelon! Life often hides infinite knowledge, waiting for those who are good at observation and hard to explore to find out.
