人谁无过，____，____。

    I'm Fang Ming. On holidays my parents often take me to the zoo in our city because I like animals. I have a lot of toy animals in my room. In the zoo I can see tigers, elephants, monkeys, pandas, bears, giraffes and many other animals. Some animals are very friendly, but some are not. Tigers, bears and lions are very dangerous. That is why they have to stay in cages. But I don't think it's good for animals to stay in cages. They should be free. The animals in cages can't be happy.

    Tigers usually live in forests and mountains. They can run very fast. They catch and eat small animals like rabbits and deer，but now they live in small rooms. They have nothing to do every day. So they walk in the cages，and they want to get out. When they are tired，they sleep. I feel sorry for them.

在我国的经济生活中，有一种“龟兔双赢理论”。龟兔赛了很多次，各有输赢。后来龟兔合作，兔子把乌龟驮在背上跑到河边，然后乌龟又把兔子驮在背上游过河去，这就是“双赢”。这个例子给我们的启示是（     ）

    听听，

    秋的声音，

    大树抖抖手臂，

    “刷刷”，

    是黄叶道别的话音。

    听听，

    秋的声音，

    蟋蟀振动翅膀，

    “嚯嚯”，

    是和阳台告别的歌韵。

    一排排大雁追上白云，

    撒下一阵暖暖的叮咛；

    一阵阵秋风掠过田野，

    送来一片丰收的歌吟。

    秋的声音，

    在每一片叶子里，

    在每一朵小花上，

    在每一滴汗水里，

    在每一颗绽开的谷粒里。
