在一个炎热的夏天，奶奶买来了一大袋苹果。我咬了一口，好酸呀！手一滑，酸酸的苹果便顺势“咕咚咕咚”的滚进了电视柜下。
On a hot summer day, grandma bought a big bag of apples. I took a bite, it's so sour! With a slip of the hand, the sour apple follows suit; Gudong Gudong; It rolled into the TV cabinet.
一个星期后，爷爷将我从房间里叫了出来，手中拿着一个长了毛的苹果诉道“这个苹果是你扔的吧！我就说最近家里怎么有果蝇？还有越来越难闻的怪味，原来就是这个小家伙搞的鬼哦！”我一脸好奇地望着爷爷手中长了毛的苹果，对爷爷的话我是左耳进右耳出，半句都没听进去。我好奇的从爷爷手中夺过苹果，跑回房间。
A week later, my grandfather called me out of the room, holding a hairy apple in his hand and saying, '; Did you throw this apple! I just said, why are there fruit flies at home recently? There is an increasingly unpleasant odor, it turns out it was this little guy who caused it! ” I looked curiously at the hairy apple in my grandfather's hand, and didn't even listen to a word he said. I curiously snatched the apple from my grandfather's hand and ran back to my room.
为什么好好的苹果会长毛呢？我的大脑被这个问题缠绕着，可一直想不通原因。于是，我抱着“打破砂锅问到底”的精神起身去问大人们。问爷爷，爷爷说不知道；问奶奶，奶奶说苹果长了霉。我不太懂，为什么要长霉？只好去问妈妈和更多的人，但她们的答案大多都和奶奶说的相似。没办法，既然不能从她们那儿得到全面的知识，我只能去找“度娘”问清楚了。
Why do good apples grow long hair? My brain is entangled with this question, but I can't figure out the reason. So, I held onto“ Break the sand pot and ask the question to the end; Get up with the spirit and ask the adults. Ask grandpa, grandpa says he doesn't know; Ask grandma, she said the apple has mold. I don't quite understand, why do we have mold? I had to ask my mother and more people, but most of their answers were similar to what my grandmother said. There's no other way, since I can't get comprehensive knowledge from them, I can only look for them; Du Niang; I asked clearly.
打开百度，直接搜索了我的疑惑，马上就出来了答案。我快速的将所有答案浏览了一遍，居然没有找到。果然是——心急吃不了热豆腐，不甘心，只好重新一字不漏的读了一遍，终于在最后找到了：
Open Baidu and search for my question directly, and the answer will come out immediately. I quickly browsed through all the answers, but surprisingly couldn't find them. Indeed, it is -; — Unable to eat hot tofu in a hurry and unwilling to accept it, I had to read it word for word again and finally found:
苹果长毛其实是发霉了。因为空气中有氧气，有细菌，细菌在苹果上繁殖，所以，苹果就腐烂了。空气中还有各种各样的真菌，还有孢子，这些东西在适宜的温度下，就会在实物上萌发生长，导致食物发霉。
The long hair on the apple is actually moldy. Because there is oxygen and bacteria in the air, and bacteria multiply on apples, they rot. There are various fungi and spores in the air, which can germinate and grow on physical objects at suitable temperatures, causing food to mold.
原来苹果没有长毛，而是被霉菌当做种田的田地了啊！真是太有趣了！
It turns out that apples don't have long hair, but are used as farmland by fungi! That's really fun!
这个发现值得被记录。今天又学到了新知识，真开心！
This discovery is worth recording. I learned new knowledge again today, I'm so happy!
