I found something.A few days ago, I found a strange thing, you guess what? Tell you, that is, the oil can kill the goldfish. You might think I’m kidding, you’re wrong, don’t believe it, just listen to me!On Sunday morning, I got up early. I, as usual, came to the goldfish bowl and looked at my little goldfish. These five small goldfish can be beautiful, like the water, like the princess, dressed in gorgeous clothes, yellow, white, black. As I ate bread, I looked at the fish. They seem to be aware of, one by one scrambling to swim over, I look at them one by one to rush to the appearance, thought: maybe they are hungry. So, I broke a piece of bread to give them to eat, at this time, suddenly from behind my father’s a broken drink, do not feed them. I was so surprised to ask, "Dad, why don’t you give them to me?" he said, "it’s up to you to find out.". When I listened to my father, I took out two goldfish and put them in another fish bowl, and I put the bread I had just broken down. Two fish saw, they scrambled to grab up, soon the bread was eaten up. I’m all eyes to look at them, but they may also have something. I thought to myself: my father must have lied to me. So, I went to play.The second day, I will come to see them, the two goldfish are heroic sacrifice. My heart is very sad, and suddenly, I found a layer of oil floating on the water, I thought: this layer of oil and goldfish and death has no relationship? So, I took this question to check my information. Finally, I found the answer in the "one hundred thousand why", the original is because the oil cut off the air, fish, because they do not suck the air to die.

A few days ago, I found a strange thing, can you guess? Well, let me tell you, that is, the oil can kill the goldfish. You might think I’m kidding, but you’re wrong, I am serious. On Sunday morning, I got up early. As usual, I came to the goldfish bowl and looked at my little goldfish. These five small goldfish are beautiful, like some princesses dressed in gorgeous clothes, yellow, white, black. As I ate bread, I looked at the fish. They swam one by one to rush out of the water, and I thought that maybe they were hungry. So, I broke a piece of bread to give them to eat. At this time, my father shouted behind me, "Do not feed them." I was so surprised to ask, "Dad, why don’t you give them to me?" He said, "It’s up to you to find out." When I listened to my father, I took out two goldfish and put them in another fish bowl. And then I put the bread I had just broken down. They scrambled to grab it, and soon the bread was eaten up. I opened all eyes to look at them, but nothing happened. I thought, my father must lie to me. So, I went to play. The next day, when I came to see them, they died. I was very sad, and suddenly, I found a layer of oil floating on the water. I thought whether this layer of oil had relationship with the death of two goldfish. So, I went to get the answer. Finally, I found it in the "Mr. Know all", which says that the oil cut off the air, so the fish die of lacking of air.
