17．　　In most schools, all students must wear school uniforms when they are at school. But not every student likes the school uniform.
　　Li Jia, a 13-year-old girl from No. 9 Middle School, said, "I don't like my school uniform at all . It is too ugly. I think young girls should wear some colorful clothes. But, I have to wear it every day."
　　However, Su Yang, also a middle school student, has different opinions. He said, "I like my school uniform. It is very beautiful. It is a symbol of my school and I like my school very much."
　　Mr. Chen, a teacher, told the reporter, "It's good for the students to wear uniforms. It saves a lot of time and money. In the past, my daughter spent much time on her clothes. But now, she seldom(很少) asks me to buy clothes for her because she has to wear the school uniform."

18．　　Birds live in trees. Squirrels (松鼠) live in trees. But do you know that some frogs live in trees, too?
　　The tree frog is hard to find. This frog can change colors. On green leaves, it stays green. On a brown branch, it turns brown. Some tree frogs can change from green to gold or blue.
　　Tree frogs have legs and wide feet. They have sticky pads at the end of their toes. These sticky toe pads keep the tree frogs from falling off.
　　Tree frogs have different colors and markings on their skin. Their eyes are different, too. Some have green eyes, some gray. Some frogs' eyes are gold, and some are bright red.
　　The sounds they make in spring and summer are different, too. One frog makes a sound like a dog barking. Another frog makes a loud noise like a snore (打鼾). There is even a frog that whistles (吹口哨)!
