Just then a boy put up his hand and said, “Miss Li, you told us that water has no color and no smell. But where can we find such kind of water？The water in the river behind my house is always black and it has a bad smell.” Most of the children agreed with him.

【小题1】The students were having their _______ class.  

As a girl, I've spent a great deal of my time on earth concerned about my weight. So I do know something about exercise. Let me tell you about the calorie-burning activities I've tried or will try.
Salsa (萨尔萨舞)
I try to maintain my weight through dancing. Dancing improves my coordination and sense of rhythm in addition to burning calories. I'm personally interested in salsa, which I find sexy and expressive(有表现力的). But I have not yet to start classes, because classes are very expensive, and I cannot find a dance partner.
Ping-Pong
Ping-pong is the national sport of China, so how could I know nothing about it?
My father is a ping-pong fan, and a really good player. He's won several informal (非正式的) matches. My relationship with ping-pong has always been on-and-off. I'll get into it for a while, and then lose interest. The reason is because I can’t find a good partner. Some stronger can depress you, while someone weaker (or just as weak) can make the game boring.
Tae Kwon Do （跆拳道）
I've recently decided to try tae kwon do as my regular exercise activity. There’s a story behind this choice: A few weeks ago, I was sitting on a bus, concentrating on a book. Suddenly, the bus became very quiet except for the sound of a woman’s crying. I looked up to see what had happened and overheard whispers that she had just quarreled with a man, and the man slapped(拍打) her face. No one on the bus dared say anything because the man looked really strong. Even now I feel ashamed I was among the silent.
That’s why I've made up my mind to learn something that will help me protect others and myself.
