Hibernation is more than sleep. It is a very deep animals temperature drops to just over zero centigrade,and its heart beats very slowly. People who find hibernating animals asleep often think that they are dead: the body feels very cold, and the creature may breathe only once every five minutes. A hibernating animal cannot feel any pain. You can touch it, or even pull its tail, without causing it to move or wake up. In its hibernating state it can even live in a poisonous atmosphere for a long time without any ill effect.
Hibernating in this way, the animal can sleep all through the winter. You might wonder how it manages to live without eating for so many months. The answer lies in two facts. Thefirst is that it has stored supplies of fat in its body during the summer and autumn. The second is connected with the main use the body makes of food -- to supply the energy for movement. We have seen that hibernating animal reduces movement to far below the ordinary level. Even the movements of the heart and lungs are greatly reduced. The animal hardly makes any movement, hardly use any energy, and hardly needs any food.
Some animals, including some bears only half is to say, they sleep during the winter, but their sleep is not deep and their body temperature does not drop, as they are warm-blooded animals. In the antumn the bear eats and eats and becomes very fat. His hair grows longer. Soon he has a thick covering of fat and fur. In November he finds a place to lie down and goes to sleep. On warm winter days he may think spring has arrived; he gets up and walks around. When he sees that the snow is still thick on the ground, he quickly goes to sleep again.

当我呀呀学语的时候，爸爸妈妈告诉我，我是一个中国人，是炎黄子孙，是龙的传人;当我懂事的时候，爷爷、奶奶告诉我，我们的祖国是一个拥有960万平方公里的大国;当我上小学时，老师教育我们要热爱伟大的祖国。
如今，我长大了，我是五年级的学生了。通过书本，我知道了祖国的幅员辽阔，地大物博，九百六十万平方公里的土地上，养育着十三亿华夏子孙，在这片美丽而富饶的疆土上，有飞流直下的黄果树瀑布，五彩斑斓的九寨沟，秀丽宜人的桂林山水，蜿蜒于崇山峻岭间的万里长城，婀娜多姿的黄山。
我知道了，祖国，是我们的家园，是我们生存的家园。我们祖祖辈辈生活在您的疆域里，您在我们的心里多么伟大，多么神圣，多么亲切。我们生活在您的怀抱里，无比幸福，无比自豪，无比骄傲。
我爱我们伟大的祖国，我爱我们美丽的家园，长大后，我要建设更美好的家园。

老师们、同学们：
大家好!
我是--。今天我在国旗下讲话的题目是：感恩祖国。蓝天下，迎着初生的晨曦，我们举行这庄严而又隆重的升国旗仪式。我们眺望着国旗冉冉升起，耳畔回荡着气壮山河的国歌，我们为这一庄严的队礼而自豪，我们因肃然于国旗前而激动。我们是新世纪的孩子，浴血奋战、硝烟弥漫的战火已离我们久远;历史的恩怨，国危的呼号也融进了历史。国旗是新年中国的一个象征。国歌，这一中国人心中最激越的旋律，穿越时空，延续着我们中华民族的伟大传统，凝聚着新中国的豪情壮志。国旗的光辉伴随着我的成长，照亮了我们前进的道路;国歌的旋律激励我们继承先辈的伟大事业，不懈奋斗。
当国歌奏响、国旗升起时，我们从那满含泪花的凝视里，从自豪激昂的“起来”声中，从挺直腰杆、溢满喜悦的容颜上，体会到了做一个中国人的自豪，同时，也掂量到我们跨世纪儿童肩头的重任：努力学习吧!祖国需要我们，世纪需要我们，未来需要我们!一面国旗，招展着一种象征：战争中的勇气，异国思乡的亲情，国际交往的尊严;一面国旗，书写着丰厚的内涵：那是祖国的土地，那是游子的归依，那是不屈的奋斗，那是国家的富强。国旗照耀航程，国歌催人警醒，那“起来、起来”的呐喊，鼓舞着我们中华民族的新一代不断创新，激励着每一个炎黄子孙自强不息。奥运健儿在第27届奥运会上的顽强拼搏，不正是这一内涵的诠释吗?
国旗，在新世纪升起;国歌，在新世纪奏响。爱国需要斗志，如高尔基所说。
