我在慢慢凝固中。听说我将来会形成了一种酸性岩。
I’m slowly setting up.I hear that I will become a “sour rock” in the future.
真遗憾，我本来想给大家带来甜蜜和幸福，可是我竟然是酸的。
It's a pity that I want to bring sweetness and happiness to everyone, but I am sour.
那么，让我闻一闻，我是山楂一样酸，还是泡菜一样酸呢？
So, let me smell, am I as sour as hawthorn, or pickle?
我左闻闻，右嗅嗅。可是我一点也感觉不到酸。
I smell myself around. But I don't sniff the sour at all.
我伸出舌头舔一舔，可还是感觉不到酸。
I put out my tongue to lick, but I still can't taste the sour.
原来，酸性岩的酸，指的是另外一种酸。岩浆能够形成许多种火成岩。有的火成岩含有少量二氧化硅，就叫超基性岩；有的含多一些二氧化硅，就叫基性岩。
It turns out that I will not become a “sour rock” but an acid rock.Magma can become many kinds of igneous rocks. With few silica, it is called the ultra-basic rock; with little silica, it is called the basic rock.
像我，含有很多很多二氧化硅，就叫酸性岩。我的身体里二氧化硅有多少呢？超过了65%。
I contain a lot of silica, called acid rock. How much silica is there in my body? The answer is much more than 65%.
二氧化硅是什么呢？其实很常见，玻璃、水晶、石英等等，这些东西里的主要化学成分就是二氧化硅。
What is silica? It's very common. Like glass, crystal, quartz, and so on, the main chemical component in which is silica.
有个小朋友告诉我，他用舌头舔过玻璃了，可一点也不酸。
A child tells me that he licks the glass with his tongue, but it’s not sour at all.
嘿嘿，其实我不仅舔了自己，我还咀嚼过自己了。我也觉得我自己不酸。
In fact, I not only lick myself, but also chew myself. I believe that I'm not sour.
