One fresh sunny day, while I was swimming in the water, I felt something special going through my gills (鳃). It was a different kind of water. I also found many of my friends became sick. Some of them were dying. I began to worry because I didn't want to get sick or die. (A) I also considered what I should do to save my friends. So I decided to do some research for my underwater life.

　　My research started. At first, I noticed there were many bottles, plastic bags and other kinds of rubbish in the water. Then I went on... I got closer and noticed a man pouring something polluted into the water. It flowed everywhere. Other people saw him do this and they followed him. (B) I found that it ___________ __________ (闻起来奇怪). Then I tasted it. It made me feel terrible. I hated it! I really wanted to tell them that it was killing us! But I couldn't.

　　I think it is so stupid of people to do bad things to the earth that they are living on! I can't understand why they are doing these People should care about the environment. If they do that, we will not have anything to worry about. I suggest they take my advice. If so, (C) 我相信每一个人将过上幸福的生活。
