暖水袋装进了开水后,就热乎得不得了。它以讥讽的口吻对热水瓶说:“冰冷的家伙,一点热情也没有,难道你也配叫热水瓶吗?看我,对别人多热情!”
不久,暖水袋慢慢地冷了。热水瓶说:“哦,原来热得快的人,冷得也快!”
哺乳动物与其它动物在许多方面都有区别。但主要的区别有两点:一是哺乳动物除极个别的以外都是胎生,是靠乳汁哺育后代的;二是哺乳动物的身体表面长着用以调节体温的毛和汗腺。
鲸是哺乳动物,母鲸用乳汁把小鲸哺养大,但鲸身上没有毛,这是为什么?
原来,鲸过去身上也是长毛的。后来由于鲸长期生活在水中,它的皮下逐渐形成了厚厚的脂肪层,这种脂肪层能够代替身上毛的功能,即起保持体温即起保持体温的作用,又使它容易浮上水面。由于鲸皮下脂肪层的增加和这种脂肪功能的发挥。鲸身上毛的功能便逐渐降低,越来越显得可有可无,最后逐渐减少,逐渐不起作用,直到几乎全部退化。但是鲸身上的毛也并不是退化得完全彻底,有的鲸的口边还留着一些毛。
不仅鲸是这样,还有些哺乳动物身上的毛也发生了退化,如大象、河马等也在退化,身上的毛越来越少了。
鲸的身上没有毛,这是鲸长期水生生活适应的结果,但是它十分全面的具有哺乳动物其它诸方面的特征。所以鲸是哺乳动物。
鲨鱼属于鱼纲鲨目,是肉食性海洋鱼类。
鲨又叫鲨鱼、鲛,是软骨鱼类。身体呈纺锤形,眼睛大都在头部两侧,无鳔。生活在深海区。全世界有300多种鲨鱼,性情温和的鲨鱼吃小鱼虾`和贝类;凶猛的鲨鱼会吃海兽,甚至攻击人类。多数卵生或卵胎生,少数胎生。
防震演习今天一大早,同学们正在早读。突然,只听上课铃打响了,本是升旗仪式,广播里却说要进行一次简易的防震演习。以前我们学校也进行过防震演习,今天又要演习了,真是兴奋,按照广播里说的一些防震要领,还没等我们反应过来,“呜呜”的警报叫拉响了。大家手忙脚乱,广播里说的要领忘的一干二净,只顾望桌子底下钻,有的同学费了好大劲也没钻进去。肖老师气得大喊:“把椅子放到桌子下面,人藏在桌子之间”。大家回过神来,赶紧按老师说的做。(哎,幸好这时演习,否则还不全完啦!?)忙活了一阵,有的同学蹲得不舒服,左动一下,右动一下,有的同学在底下聊天讲话,全不当回事。忽然,警报停了,广播里说赶快下楼,不少同学“解脱”了似的,舒展了一下筋骨,排队去了。到了楼梯口,大家“谈笑风生”,如果是真的地震,估计只能听到“sos,救命”了。到了大操场,大家抱头蹲下,等人到齐后,老师便开始讲“防震小知识”。大家约用了三分钟全部“逃离”成功,沈老师最后总结说:“在我们遇到地震时,不要慌张,井然有序才有可能获得最大生机。”我想到了上星期学的《船长》这篇课文,正是哈尔威船长沉着镇定,让大家按秩序才得以使60个人生还的吗?在地震时不能自私,你抢先我也要抢先,那么,谁也逃不出去。以前看过一篇文章,讲一个人在学校里做了一个实验,一个仅可供一个球出入的瓶子里有好几个同样的球,每个球都有个线给孩子们拉着,一说开始,便要用最快的速度把球拉出来,孩子们一个接一个的拉出来,很快完成了任务。这就象人一样,如果像人一样,如果一起拉,大家卡在门口谁也出不来。沈老师还说:“在户外遇到地震时,要远离高大建筑物,在高楼不能坐电梯也不能跳楼。”是啊,如果我们懂得逃生知识,有秩序,便可以以最快最好的逃离。有一篇文章写了几个孩子在海上划船找不到陆地,一个孩子靠自己的知识让大家跟着海鸟最终救了大家。即使只是一次小演习,我们也得认真对待。人有情但灾难无情,我们只有懂得更多的自救知识,才能减少灾难多我们的害。
面对一篇寓言类材料作文,我们首先要理解这则寓言故事,然后再来认真审题。也就是说我们要读懂寓言故事里讲的是什么,它的寓意是什么,这应该是最基本最起码的要求。读懂寓言,首先要让学生懂得寓言这一文体的特点。“寓言,文学体裁的一种。以散文或韵诗的形式,讲述带有劝谕或讽刺意味的故事。结构大多短小,主人公多为动物,也可以是人或非生物。主题用意在惩恶扬善,多充满智慧哲理。”【辞海“寓言”(fable辞条】“寓者,寄也;言者,话也”。所以寓言就是“寄托的话”。作者把自己要说的话寄托在一个虚构的小故事里。寓言的表现方式是由此及彼,通过借古喻今、借物喻人、借小喻大或借此喻彼的手法,揭示事物丰富的内涵和蕴含的深刻道理。了解了这些,我们也就不难理解材料,不难审题了。
例题1:动物园里来了一位哲学教授,向动物们传授哲学。哲学教授讲了好多空洞的理论,接着说:“任何事物都必须从基础做起,就如任何建筑都必须从底层做起。”有一只青蛙听得不耐烦了,就向教授发问:“请问教授,真的所有建筑都必须从底层做起吗?”哲学教授瞄了青蛙一眼:“当然!井底之蛙!”青蛙反击说:“正因为是井底之蛙,我才问你--难道打井也从底层做起吗?”哲学教授哑口无言。动物们纷纷说:“是啊,即使是井底之蛙,他也有自己独特的.见解,何况不是呢?”
要求全面理解材料,但可以选择一个侧面、一个角度构思作文。自主确定立意,确定文体,确定标题;不要脱离材料的含意作文,不要套作,不得抄袭。
读完这则寓言故事,我们应该明白,它讲的是一个哲学教授和青蛙以及其它动物们之间的故事,结果是这个哲学教授被青蛙和其它动物们驳倒。教授被驳倒是因为:(1理论与实践脱离。(2具体问题不能具体分析。(3说话过于绝对。青蛙把教授给驳倒了是因为:(1勇于质疑。(2敢于挑战权威。动物们反驳教授是因为:教授只信自己,小看他人。
理解了这些,我们也就不难审题了,这个故事就是要告诉我们:理论要与实践相结合,学会具体问题具体分析,对事物下的结论不要太过绝对,看问题也不能太过绝对;要敢于质疑,敢于挑战权威;要看到别人的长处。
随着一阵铃声,同学们不顾一切,飞奔向楼下去,可是又被广播叫起。
这就是我们学校举行的防震演习。但上课铃一响。同学们便冲下楼,这本是原来的安排。但是临时改变的策略则使我们大大的失去了体力。主任说什么等铃声响后,还要一班一班的“逃”,只有按照她所念的顺序跑才行。
第二次开始,当听到广播中响出602班开始时,又再一次出现刚才的一幕,且我们不用1分钟便全班抵达操场,这使我们十分高兴!
在演习中,我看到同学们认真的神情,想到,我自己也应该努力才行啊!!我飞快的奔跑着的时候,感觉跑得还是很快的!!
如果真的出现地震的话,按我们的速度,一定会安全的脱离危险的。但在演习中,我也看到同学们不规范的地方,有的同学居然还手牵着手一起跑,这个紧张的时刻,是不能出现这种状况的啊,这样会危及到生命的。这种不规范的行为也不能再犯了啊!这是绝对不可行的!
这次防震演习,使我们懂得了在地震来临的危急时刻,应该怎样保持着镇定的心理。举行这种防震的演习是意义重大的,我们也不能忽视!!
失望和希望一同去寻找成功。在通往成功的道路上,它俩遇到了困难。失望一见到困难,便退却了;希望却勇敢地迎了上去。经过顽强拼搏,希望终于把困难踩在了脚下,获得了成功。
失望后来问希望:“为什么你能战胜困难,而我却不能呢?”
希望回答说:“因为我视困难为垫脚石,而你却把困难当成了拦路虎。”

As is shown above, a leader father is sitting in the chair with a seal grasping in the hand, and a lot of money beside him. He seriously said to his son that there is more to life than just money -it is power. Simple as the picture is, but a profound truth is reveled in the picture.
I surely disagree with father ’s philosophy. As a leader, he shouldn ’t use his power to make money. It is his duty to serve people wholeheartedly, just one person said “with great power comes great responsibility ”. If he stick to his philosophy. I believe that he will spend the rest of his life in prison. What’s worse, he could affect his son ’s philosophy, guiding him in the opposite direction , nothing can be done to reverse the trend itself. The only solution is to change father ’s philosophy. Because of many greedy officials in China, it is time to reverse the trend itself by establishing new policy. As Chinese always has been our confidence that we can change for the better and better.
In my opinion, there is more to to life than just money -it is happiness, nothing is important than happiness. We can live a colorful life in our spare time.

今天下午,第二节课刚刚开始,老师对我们说:“针对地震,为了提高防范自救能力,掌握安全防护知识,我校今天要做一次防震演习。大家要做到两个方面:第一是自我保护,同学们要双手抱着头,钻到桌底下。第二是逃生,大家要快速跑到操场上排好队,确定好安全的位置。”老师的话说完不久,学校的警报器就响了,我们立即钻到课桌底下。同学们都很紧张、也很害怕,他们可能是在想:“如果真的地震了,那多可怕呀!”老师叫我们起来的时候,还没过两分钟,第二次警报器又响了。同学们有条有序并迅速的离开了教室,快速的跑到了操场。这时候,老师开始清点人数,看到同学们完整无缺,心里放心多了。虽然是演习,但是我们还是挺紧张的。有个别同学在逃生演习中,由于紧张摔倒了,被其他同学搀扶了起来。
可见,演习也增进了我们同学互相帮助的友谊,太好了。我们要熟悉逃生路线,即使是发生地震,也能有条有序的、迅速的做到安全疏散,安全撤离,确保生命的安全。通过演习,让我们学到了安全防护知识,达到遇事不惊慌、保持镇静、积极应对、树立自我保护意识,这样还可以让我们提高对突发事件的应变能力。
这堂令人难忘的演习课实在是太有意义了!
