Do you know how to keep fish at home?

The fish need room. They must not be crowded（拥挤）. Fish need oxygen(氧气). Fish get it from water in the tank. There must be enough water for all fish in the tank. So the size of the tank is important..

In the tank many people put small plants(植物). They give oxygen to the water. Plants help in other ways, too. Fish can nibble(轻咬)on the plants. They hide in the plants and sleep, lay eggs there.

Both the plants and fish need light. You can put near a window. It will get light there. But remember: a window may let cold air in. The cold can kill(杀死) your fish. Too hot water can kill your fish, too.

　　云南本是个诗歌的家乡，路南和达西歌舞早著名全国。这一回却更加丰富了我的见闻。

　　这是种生面别开的场所，对调子的来自四方，各自蹲踞在松树林子和灌木丛沟凹处，彼此相去虽不多远，却互不见面。唱的多是情歌酬和，却有种种不同方式。或见景生情，即物起兴，用各种丰富譬喻，比赛机智才能。或用提问题方法，等待对方答解；或互嘲互赞，随事押韵，循环无端。也唱其他故事，贯穿古今，引经据典，当事人照例一本册，滚瓜熟，随口而出。在场的既多内行，开口即见高低，含糊不得，所以不是高手，也不敢轻易搭腔。那次听到一个年轻妇女一连唱败了三个对手，逼得对方哑口无言，于是轻轻地打了个吆喝，表示胜利结束，从荆条丛中站起身子，理理发，拍拍绣花围裙上的灰土，向大家笑笑，意思像是说，“你们看，我唱赢了”，显得轻松快乐，拉着同行女伴，走过江米酒担子边解口渴去了。

　　这种年轻女人在昆明附近村子中多的是。性情开朗活泼，劳动手脚勤快，生长得一张黑中透红枣子脸，满口白白的糯米牙，穿了身毛蓝布衣裤，腰间围个钉满小银片扣花葱绿布围裙，脚下穿双云南乡下特有的绣花透孔鞋，油光光辫发盘在头上。不仅唱歌十分在行，而且大年初一和同伴各个村子里去打秋千（用马皮做成三丈来长的秋千条，悬挂在高树上），蹬个十来下就可平梁，还悠游自在，若无其事！
