球球的可爱还表现在吃相上。它呀，只要我一有好吃的，就不管三七二十一地往我身上冲，一边摆动着它小小的、打卷的尾巴，有时候，见了肉骨头都比见了我还亲。有一次，我给球球做了一份丰盛的“红烧肉大餐”。它紧盯着食盘，还没等我把放稳，球球早迫不及待的吃了起来，像饿了几天似的。我终于忍不住了，对它说：“又没人抢你的，能不能别这么护食?”球球好像听懂了我的话似的，冲我摇了摇头，扇了扇小耳朵，摆了摆尾巴，好像在认错，那样子，可爱极了。咦，它什么时候把红烧肉都吃光了?!

我爱我的球球!

Animals are natural resources that people have wasted all through our history。 Animals have been killed for their fur and feathers， for food， for sport， and simply because they were in the way。 Thousands of kinds of animals have disappeared from the earth forever。 Hundreds more are on the danger list today。 About 170 kinds in the United States alone are considered in danger。

Why should people care？ Because we need animals， and because once they are gone， there will never be any more。 Animals are more than just beautiful or interesting。 They are more than just a source of food。 Every animal has its place in the balance of nature。 Destroying one kind of animal can create many problems。 For example， when farmers killed large numbers of hawks， the farmers stores of corn and grain were destroyed by rats and mice。 Why？ Because hawks eat rats and mice， with no hawks to keep down their numbers， the rats and mice multiplied quickly。

Luckily， some people are working to help save the animals。 Some groups raise money to let people know about the problem。 And they try to get the governments to pass laws protecting animals in danger。 Quite a few countries have passed laws。 These laws forbid the killing of any animal or plant on the danger list。 Slowly， the number of some animals in danger is growing。

Although it is only a small animal, but it also has a kind heart. Once when Grandpa was ill in hospital, he went hungry! Even if we bought it its favorite loach fish, he refused to eat it. It wasnt until the grandfather left the hospital half a month ago that he was happy to eat, and it was really a love and pity at the time.

但有时候，它也很“可恨”!一天，它在玻璃缸里憋的难受要出来，我看它着急的样子就好心帮它，我用食指和大拇指小心地捏住它的壳，轻轻地把它拿出来，没想，到它竟然用尖尖的爪子挠我，真是不识好人心!虽然我很生气，但看到它开心的在地上自由的到处玩耍，我也替它高兴。

But sometimes, its also "hateful.""! One day, it in the glass bowl to hold uncomfortable, I think it will help it in such a hurry, I use the index finger and thumb carefully pinched its shell, gently put it out, didnt think it even with the sharp claws on me, is really not good people!

Some places

completely using the cliffs, rivers and lakes as a natural barrier, it can be called art beats nature. The

Great Wall, as a great project, become the Chinese nation is a valuable heritage.

长城修筑的历史悠久，工程雄伟浩大，是世界少有的奇迹。长城东西南北交错，绵延伏于我们伟大祖国辽阔的土地上。它好像一条巨龙，翻越巍巍群山，穿过茫茫草原，跨过浩瀚的沙漠，奔向苍茫的大海。根据历史文献记载，有20多个诸侯国家和封建王朝修筑过长城，若把各个时代修筑的长城加起来，大约有10万里以上。其中秦、汉、明3个朝代所修长城的长度都超过了1万里。现在我国新疆、 甘肃、 宁夏、 陕西、 内蒙古、 山西、河北、北京、 天津、 辽宁、 吉林、 黑龙江、河南、山东、湖北、湖南等省、市、自治区都有古长城、峰火台的遗迹。其中仅内蒙古自治区的长城就达3万多里。

明朝在“外边”长城之外，还修筑了“内边”长城和“内三关”长城。“内关”长城以北齐所筑为基础，起自内蒙古与山西交界处的偏关以西，东行经雁门关、平型诸关入河北，然后折向东北，经来源、房山、昌平诸县，直达居庸关，然后又由北而东，至怀柔的四海关、与“外边”长城相接，以紫荆关为中心，大致成南北走向。“内三关”长城在很多地方和“内边”长城并行，有些地方两城相隔仅数十里。除此以外，还修筑了大量的“重城”。雁门关一带的“重城”就有24道之多!

长城是我国古代劳动人民创造的奇迹。自秦始皇开始，修筑长城一直是一项大工程。据记载，秦始皇使用了近百万劳动力修筑长城，占全国人口的1/20!当时没有任何机械，除运土、运砖可以用毛驴、山羊能爬山的牲畜外，全部劳动都得靠人力，而工作环境又是崇山峻岭、峭壁深壑。可以想见，没有大量的人群进行艰苦的劳动，是无法完成这项巨大工程的。

万里长城的工程量，据粗略估计，仅以明朝修筑为例，若将其砖石、土方用修筑一道厚1米、高5米的大墙，可环绕地球一周有余。如果用来铺筑一条宽5米、厚35厘米的马路，那就能绕地球三四周了。如果把所有朝代所修的总计10万里来计算，则这道长墙可绕地球十几周，这条马路，可绕地球三四十周。

“因地地形，用险制塞”是修筑长城的一条重要经验，在秦始皇的时候已经把它肯定下来，司马迁把它写入《史记》之中。以后每一个朝代修筑长城都是按照这一原则进行的。凡是修筑关城隘口都是非曲直选择在两山峡谷之间，或是河流转折之处。或是平川往来必经之地，这样既能控制险要，又可节约人力和材料，以达“一夫当关，万夫莫开”的效果。修筑城堡或烽火台也是选择在“四顾要之处”至于修筑城墙，更是充分地利用地地形，如像居庸关、八达岭的长城都有是沿着山岭的脊背修筑，有的地段从城墙外侧看去非常险峻，内侧则甚是平缓，收“易守难攻”之效。在辽宁境内，明代辽东镇的长城有一种

叫山险墙、劈山墙的，就是利用悬崖陡壁，稍微把崖壁劈削一下就成为长城 了。还有一些地方完全利用危崖绝壁、江河湖泊作为天然屏障，真可以说是巧夺天工了.长城，作为一顶伟大的工程，成为中华民族的一份宝贵遗产。
