蚂蚁 - 简介蚂蚁是一种人们十分熟悉的动物,它的踪迹几乎遍布全球,除南极洲之外,其它各洲都可以见到它们,以热带地区最多.蚂蚁也是一种非常古老的动物,它在地球上生活的历史超过了一亿多年.地球上到底有多少种蚂蚁,目前还没有一个公认的数据,各种资料由于来源渠道不同,相差甚远,产生这种现象的原因可能与蚂蚁个体太小、分布地域太广等原因有关,而生活在我国境内的蚂蚁已经查明的大约有500种.蚂蚁的个头因种类不同相差很大,大的超过花生米,小的只有芝麻般大,从身体的颜色来看,有红、黑、褐、黄等多种,少数还有金属光泽.蚂蚁的一生要经历卵、幼虫、蛹和成虫几个阶段,发育全过程大约要经过8至10周的时间.它们的食性复杂,一般来说比较低级的种类为肉食或杂食性,比较高级的种类为植食性.
在昆虫世界里,蚂蚁是一种比较高级的社会性动物,它们常成群地活动.每群中的蚂蚁一般可以分为繁殖蚁、工蚁和兵蚁三大类.雄蚁和具有生育能力的雌蚁都有翅膀,交配后不久雄蚁便死去,雌蚁的翅膀脱落,并开始营巢、产卵.最早出生的卵从孵化到长成全都由雌蚁亲自照料,这些小家伙们的食物都来自于雌蚁体中,相当于哺乳动物的乳汁.随着时间的推移,这批“子女”慢慢地长成,所有的“家务事”都由它们来承担,雌蚁则成为这个“家族”中专门负责产卵的蚁后.蚁后每天产卵的数量因种类的不同略有一些差异,一般在500至1 000粒左右,一只蚁后一生能产几万、几十万粒甚至更多的卵,由于卵巢发育使腹部不断膨胀,最后连吃食也得由工蚁来喂,行动也依靠工蚁来抬,蚁后还有一高招,那就是它无论是否受精都能产卵,没有受精的卵将发育成雄蚁,受精卵都发育成雌蚁,雌蚁中只有极少数的具有生育能力,它们长大后必须自立门户,那些不能生育的雌蚁就成为工蚁和兵蚁,工蚁和兵蚁都没有翅膀,我们平时看到在地面爬动的基本上都是工蚁.
蚁群中的工蚁最辛劳,筑巢、觅食、抚育后代都由它们来承担.兵蚁的头部发达,那比一般蚂蚁要大许多的上颚,是攻击其它动物的武器,当遭到别的蚁群袭击时,它们会拼死地搏斗,有时我们在地面看到成堆的死蚂蚁,那就是交战双方留下的尸体.除此之外,少数种类的工蚁腹部具有螫针,能施放出有毒的液汁来抵御敌害.
在昆虫世界里,蚂蚁的社群行为可以说是最复杂的了,从群体的大小来看,多的达到数十万到上百万,例如军蚁,少的只有数十到一千来只,例如小家蚁;从巢穴方面来看,大多数蚂蚁的巢穴都建在地下深处或石块、建筑物之下以及植物根的附近,少数种类的巢穴高出地面,形成蚁丘,还有把巢建在树上的.从生活习惯方面来看,更是五花八门.有一种生活在南美洲热带地区的军蚁,它们不筑巢,平时列队在丛林中四处游荡,将沿途碰到的各种昆虫以及无脊椎动物一扫而光,蛇、蝎、蜥蝎等动物遇到它们也在劫难逃,除了蚁后周期性产卵时,蚁群休息几天,然后就又携带着幼虫一起迁移;还有一种以蚜虫产的蜜露为食的蜜蚁,它们具有放牧的本领,能帮助蚜虫越冬,从一株植物迁移到另一株植物以及抵御其它天敌的袭击,蚜虫就像是它们的“奶牛”一般;还有一种生活在非洲的去头葡萄蚁的生活习性也十分有趣,其蚁后故意让香家蚁将其拖到巢中,然后咬掉香家蚁蚁后的头,将香家蚁的工蚁变成它的“奴隶”,所产的卵由这些被奴役的工蚁来照看.诸如此类,不一而足,这些千奇百怪的习性形成原因是蚂蚁在长期的生物进化中,不断地适应环境的结果.
在蚂蚁世界里,除雄蚁的复眼和3只单眼比较发达之外,雌蚁和工蚁的视力高度退化,它们主要靠头上的触角来感知外界事物.触角的作用有两种:其一是可以探明周围的环境,例如遇到障碍物时,通过触角可以感知其大小、形状、硬度等方面的情况,同类也是通过触碰触角来传递信息.其二是具有嗅觉的作用,蚂蚁能从腹部末端的肛门以及腿部的腺体分泌出一些带有“家族”性气味的化学物质,外出活动时将其留在沿途作为“路标”,它们到离巢数十米远的地方活动也不会迷路,通过嗅闻气味仍可找到自己的“家”.此外根据气味还可以很快地识别自家人,防止外人混入.蚂蚁留下的气味能保持比较长的时间,如果因意外被破坏,它们还可以根据太阳来确定巢穴的位置.
蚂蚁个子虽说不大,但力气却不小,它能搬运的重量是它体重100至400倍的物体,能拉动的重量是自己1 700倍的物体,而对于号称万物之灵的人类来说,没有一个人能举起重量超过自身体重3倍的物体,所以,蚂蚁是动物世界中当之无愧的大力土.蚂蚁的力气为什么会如此之大呢?科学家经过研究发现,蚂蚁肢体上的骨头长在肌肉外面,它的肌肉纤维里含有特殊的酶和激素蛋白,稍加活动就能释放出巨大的能量,而且几乎没有损耗,这是其它动物所不能相比的.蚂蚁的这一特长引起了仿生学家极大的兴趣,他们试图制造出“人造肌肉发动机”,那样只需要少量的?可以使能源的利用率达到70%至90%.蚂蚁还是天生的“数学家”,当一只蚂蚁遇到自己搬不动的物体时,它会通知蚁巢中的其它工蚁来帮忙,这些来帮忙的工蚁刚好能将物体搬走,在根据搬运对象确定劳动力的多少方面,达到了十分精确的程度

一天,我和几个伙伴兴致勃勃地用湿泥在土坑上建造“宫殿。烈日当头,我们不想多待。只是用手一捏、一拍、马马虎虎粘在一起,便竣工了。
正准备回家时,却意外在土坑上发现了一个巨大的蚂蚁窝,对我来说无疑是一个神秘的外星飞碟。
挖出以后,一座富丽堂皇的宫殿顿时呈现在我眼前。蚂蚁窝里通道多得犹如繁星;有似一条条通风管道。怪不得蚂蚁窝被称为全天下最宏伟的建筑;怪不得蚂蚁窝被称为全天下最精致的建筑;怪不得蚂蚁窝被称为全天下最舒适的建筑。这实在是一件艺术品;一件价值连城的宝贝;一件独一无二的珍宝。
是谁造了它呢?是蚂蚁,是一群生命卑微的蚂蚁。在如此坚硬的土坑里;在坚是遍布的土坑里。一群微不足道的蚂蚁却创造了奇迹。蚂蚁能力如此微小,身份如此卑微,生命如此脆弱。却在烈日炎炎下,在有生之年里,不顾旁人的看法,为着生命的意义,为着精致、宏伟、舒适的人生目标,唱着搬土,运石,前进……的生命之歌,尽力做好自己力所能及的事情。无论是刮风下雨;无论是烈日炎炎;无论生,死;无论……
和蚂蚁的生命相比,弱小、卑微、脆弱是否离我更远呢?我是否应该把力所能及的事做得更精致、更仔细、更一丝不苟呢?
让我也把力所能及的事做得更好一些吧!
也许,当我做完之后,我会感到一丝自豪、一丝成就感!

出于好奇,我拿出一个纸da杯,将一些矿泉水倒进了纸杯里,随手抓了几只蚂蚁放了进去。面对着这突如其来的“洪水”,这些蚂蚁惊慌失措,在水中拼命地挣扎,触角不断地摆动,好像在发出求救信号。短暂的慌乱过后,蚂蚁们好像不再害怕了,它们将腿伸开,拨动着纸杯中的矿泉水,犹如在划动着船桨。渐渐地,有几只蚂蚁聚拢到了一起,它们仿佛在商讨着逃离“洪水”的办法。蚂蚁们一边商讨,一边摇摆着触角发出信号,好像在告诉其它伙伴怎么逃离。最后,这些蚂蚁一步一步地游到纸杯的边沿,逃离了“洪水”。 紧接着,这些蚂蚁赶忙爬出了纸杯,排着整齐的队伍又加入到大部队里面去了。
过了一会儿,我将一块小饼干放在离蚂蚁们不远的地方。咦,蚂蚁真灵巧,闻到了饼干的香味。有一只蚂蚁首先爬到了饼干的旁边,围着饼干绕了一圈又一圈,然后爬了上去。接着,又有四、五只蚂蚁爬过来,它们也在饼干上爬来爬去,跟前面来的那只蚂蚁碰了一下触角,好像在嘀咕什么。大约过了一分钟,这些蚂蚁一起爬回到大部队的队伍当中。怎么这些蚂蚁都不吃饼干就走开了?难道饼干不好吃吗?过了一阵子,一支庞大的蚂蚁队伍来到了饼干旁边,望了望比自己身体大了几十倍的饼干,它们似乎在担心能不能搬得动。过了好久,这些蚂蚁个个全身不停地在摆动,仿佛在做热身运动。然后,蚂蚁们纷纷钻到了饼干的下面。喔,偌大的饼干竟然给蚂蚁们齐心协力地扛起来了。看着蚂蚁们步伐一致地把饼干一步一步扛回洞穴,我真是感到惊讶,原来集体的力量是那么强大,难怪俗话说——“人心齐,泰山移”!

Students need enough sports and activities to do physical exercises and relax, but in some schools they are not given enough time to do outside activities. It's harmful for students' growth. Teachers ask students to spend most of their time on studies. But when they feel tired and bored, students can't concentrate on studies. They are in bad health.
It's necessary to give students enough time to do outside activities. After good relaxation and rest, studens will work harder.
Pay attention to students' health and growth.
学生们需要足够的运动和活动来锻炼和放松,但是一些学校没有给予学生足够的时间从事课外活动,这对学生成长是有害的。老师为了让学生得高分,要求他们把大部分的时间放在功课上。但是当学生疲惫厌烦时,就不能集中精力学习。他们的身体也不好。
给予学生足够的时间从事课外活动是很必要的。休息好和放松后,学生会更加努力学习。
请关注学生的健康和成长。

金钱是幸福之本?:
Directions: For this part, you are allowed 30 minutes to write a composition on the topic Can Money Buy Happiness?
You should write no less than 100 words and you should base your composition on the outline (given in Chinese) below:
1.有人认为金钱是幸福之本(source of happiness)
2.也有人认为金钱是万恶之源(root of all evil)
3.我的看法
Can Money Buy Happiness?
范文:
Can money buy happiness? Various people have various answers. Some people think that money is the source of happiness. With money, one can buy whatever he enjoys. With money, one can do whatever he likes. So, in their minds, money can bring comfort, security, and so on. Money, as they think, is the source of happiness.
But there are still a lot of others who think that money is the root of all evil. Money drives people to steal, to rob, and to break the law. A lot of people became criminals just because they were in search of money. And in the Western countries, there is nothing that can’t be bought by money. Many people lose their own lives when hunting it.
I think that money is essential to life and we cannot do without money. But even though money is necessary to life, it can’t buy happiness. Happiness is not something that can be measured by money. It is a state of mind. One can have plenty of money, with which he can buy whatever he wants, and at the same time he is not happy because he is never satisfied or he is troubled by various kinds of problems. Therefore, although money is necessary for a happy life, it can’t buy happiness.

Nowadays in china, many students are the only child in their family. they are the apple of their parents' eyes or even their granparents', so they are free of any house work or menial labor. and moral education is no more than some bookish thing. studentsare largely dependent on their parents and teachers.
To educate them to be independent, the most effective way is to let them experience on their own. therefore,they are better to be given the opportunity to get some train at school-to clean the washing room,which can be regarded as part of the moral education
4.一件难忘的事情(An Unforgetful Thing)
How time flies!I'm fifteen years now.During the long time,there was one thing that I will never forget.
The Spring Festival is our traditional festival.During the Spring Festival,people usually visit their friends and relatives.When I was 9 years old,my family took the bus to my grandparents' to say "Happy New Year" to them.
In the bus,I had a good seat.At 7:30,the bus came to a village.A woman got on with a baby in her arms.At that time,there was no seat.But she must look after her baby carefully.She had to stand next to me.I wanted to stand up and let her sit down,but I was afraid of hearing the other people say"That girl want to be praised."I looked around.Most people were looking out of the windows and some were sleeping.Suddenly,a little boy behind me,stood up and made room for the woman.She said "Thank you very much" with a big smile.The boy smiled,too.When I told my cousin about it after that,he said "The child is the father of a man." I'm very ashamed.Why could't I do the same thing as the little boy did?
From that I learn that we should do our best to help people who need help.If everyone makes a contribution to helping others,the world will become much more beautiful!

工作与娱乐(Work and Play)
Work and play do not contradict each other; in fact, they complement each other. As the saying goes, %26quot;All work and no play makes Jack a dull boy.%26quot; A life burdened with work leads you nowhere, for you would get tired and bored with your daily routine work. On the other hand, proper recreation will relieve the tension and discomfort of our monotonous life because it offers you various ways to let out your pent-up emotions.
What I usually do to relax after school is jogging and seeing movies. Usually I don't spare time for exercise, but I value the physical education class at school. Jogging several rounds in the field certainly relieves the day's pressure. On weekends, I'll catch the morning movie for my visual enjoyment. I feel revived and energetic for another week's work-load.
工作与娱乐并不互相冲突,事实上,它们之间的关系还相辅相成。有句格言说:「整日工作而没有休闲娱乐,会令人变得沉闷乏味。」被工作重担压得喘不过气来的生活,将使你一事无成,因为你将对一成不变的例行公事感到厌烦。由另一方面来说,适度的娱乐活动能提供各种管道,来渲泄你被压抑的情绪,减轻单调生活中的紧张与不悦。
放学之后,我最常做的休闲活动,便是慢跑与看电影。通常我并不特地拨出时间来做运动,但是我很重视学校的体育课。在操场上慢跑几圈,无疑地可以减轻一天的压力。在周末时,我都去看早场电影,享受视觉飨宴。如此一来,我将有如再生般的充沛活力,去面对下一星期的工作量。
6.No Pains,No Gains
It is obvious to everybody that the only way to achieve one’s goal is to work hard. Just as the old saying goes "no mill, no meal". Have you ever seen a man who succeeds just by idling about? Of course, the answer is "No". So we know if you want to gain something, you will have pains.
The farmers harvest by a year of arduous work; the scientists gain achievements by years of devoted researches; students get good marks by working hard; even the little ants have their food by working hard day and night. 1 know there are always some people who wait for the opportunities falling on them. They may attribute their failures to lack of good chances. Therefore, there are so many people gaining nothing at last. Clever men know that the more effort they make, the bigger chance they will have to be successful.
So, when others achieve their aspirations and you still gain nothing, don’t complain about the unfair fate and don’t give up, either. Remember: no pains, no gains.
不劳则无获
大家都知道,获得成功的唯一途径就是辛勤付出。正如那句老话所言:不推磨,没面吃。你见过一令人靠无所事事获得成功吗?答案当然是否定的。因此,我们应明白有劳才有获这个道理。
一年的辛苦劳作使农民获得丰收;科学家经过多年钻研后取得成就;学生努力学习才取得;好成绩;就连小小的,蚂蚁也是靠日以继夜的劳动才获得了食物。但依旧有许多人渴望着天上掉馅饼,他们失败时,会归罪。于运气不好,所以最终他们什么也不会得到。聪明人知道,越努力去做,成功机率越大。
当你看见别人成功而自己仍无所事事时,不用抱怨命运不公,更别轻易放弃。记住,有付出才会有收获。

当今社会,我们应该看重诚信还是看重能力
据报道,某地一女青年用假文凭通过公司面试,进入某公司工作.她工作能力较强,工作干得很出色,但后来假文凭被查出,公司以她缺乏诚信为由解雇了她.
你认为公司这种做法对吗 当今社会,我们应该看重诚信还是看重能力 请根据这一件事件选择其中某一种观点,结合你身边的事例,写一篇100词左右的短文,谈谈你的看法,重点表述你持某种观点的理由,题目自拟.
参考词汇:文凭 diploma 诚信 honesty
Possible versions:
Honesty Comes First
I think it is right to fire her, though she is now good at the job. Her fake diploma does help her, but it also does harm to others. It is unfair for others to compete in the job hunting. So I think honesty should come first. Nowadays, more and more students tend to cheat in exams. I think it is a serious problem. Though you can get higher marks and be praised by others, you should clearly realize that it does do harm to others and even yourself. The fame is temporary and you won't get real knowledge.
In a word, we should be honest and honesty must come first.
Society Calls For Honesty
Personally, I am in favor of the company's decision on firing the woman. Abilities are not always the most important, though one's personality of being honest is what really matters. If the woman was not laid off, no one could guarantee that she wouldn't go against honesty any more.
Society calls for honesty. When accepting someone as a friend, one will always take his honesty, rather than abilities into account. However, some of our own actions are the same case with that young woman. Take cheating in exams for example. Have you ever cheated in exams Most of your answers to this question, I think, are %26quot; yes%26quot;, but the marks are really worth selling your honesty out
A fake diploma will not always help, but the personality of being honest will go with you forever and make things smooth. Now have you attached importance to honesty Have you made up your mind to be an honest man.

Water
Water is very important for living things. Without water there can be no life on earth. All animals and plants need water. Man also needs water.
Water is found atmosteverywhere. Even in the driest part of the world there is some water in the air.
As we all have found out, water may be a solid, or a liquid or a gas.When it isa solid, it may be as hard as brick, When itis a liquid, you can pour it out of a container. When it is a gas, you cannot see or feel it.
Although about 70 percent of the earth’s surface is covered with water,there are many places in the world still running out of water. So we should make good use of water on earth.

水对生物很重要,没有水,地球上就没有生命。所有的动植物都需要水。人类也需要水。
水几乎无处不在。即使在世界上最干燥的地方,空气中也有水。
水,正如你所了解的,有固态、液态和气态。当它是固态时,它可以像砖一样硬;当它是液态时,你可以将它从容器中倒出;当它是气态时,你看不见或感觉不到它。
虽然地球表面70%是水覆盖着,世界上仍有许多地方缺水。所以我们要好好利用地球上的水。
9.论因特网(On the Internet)
The Internet seems to have become an indispensable part in modern lire. This is because the Internet has a lor of advantages. To begin with, the Internet provides people with enormous amounts of information in a fraction of a second. With this easy access to the Internet, searching for information has become easier than ever before. Besides, the Internet changes the way people communicate with each other. E mail allows us to write to our friends and receive letters from our friends cheaply and instantly. Furthermore, the Internet has revolutionized business. E-commerce enables people to do business and go shopping at home easily and conveniently. Finally, the Internet plays an important role in mass education.
However, the Internet also has some unfavorable aspects. Cyber crime causes a great loss in people's property. Computer viruses bring us lots of trouble. Trash mail is always a nuisance to everyone. Worst of all, pornography may corrupt people, especially young people.
In a word, the Internet has both merits and demerits. But on the whole, it brings peop[e more benefits than harm. It is suggested that a clever use be made of this modern technique for the benefit of all people.
10.浪费(waste)
Mankind is wasting things every'where and everyday. Wherever we go, we can see that paper, bottles and cans are thrown away; food is wasted just because of poor taste; clothes are discarded simply due to their old fashion. Not only things and money are wasted, but natural resources are abused as well. Trees are cut down merely for fuel; wild animals are killed simply for meat and fur; oil and coal are exploited in a bad way.
The worst example of man's waste is the waste of time. Many people tend to spend their time on worthless things, such as wandering about in the street, gossiping in the office, sleeping too much during the day. As we know, time is very precious to us since it passes by and never returns. The waste of time amounts to the waste of life.
It is time to call for an end to the waste. On one hand, we must save on natural resources and make full use of them; otherwise human beings will be faced with the shortage of natural resources and suffer from the pollution caused by waste. On the other hand, we must trea sure our time. Only with our time devoted to the study and the work for the people, will we never regret the life we have had.

1.生活处处有科学,科学处处在。
一天,我和小伙伴在外面玩耍。突然,我们发现有一群蚂蚁正在忙着要干什么。我听说过蚂蚁害怕樟脑球的气味,想去做一下试验,证明这是不是真理。
首先,我们捉来了2只小蚂蚁。我们用樟脑球在蚂蚁的前面画了一条线,蚂蚁转了转,然后冲破了那一条线,跑了。我不假思索,蚂蚁怎么跑走了呢?蚂蚁不是害怕樟脑球的气味的吗?疑团未揭开,带着好奇,我们又捉来了2只小蚂蚁。
像原先一样,我们在蚂蚁的前面画了一条线,蚂蚁仍然转了转就冲破了画线。我们又在蚂蚁的前面画了一条线,蚂蚁想冲破,在向画线逼近,似乎在说:就这么一条线,就想把我们困住!你们未免也太小瞧我们了吧!哈哈哈~ ~ ~ ”。蚂蚁说着说着,便得意洋洋的冲向画线。我想,这次的试验一定又是以0分为结局了。当我这在叹息时,蚂蚁像被一阵风吹了回来似的,蚂蚁不敢冲破画线了。
当蚂蚁累得精疲力尽,四肢无力的时候,我们又在蚂蚁的周围画了一个大圆圈。这下蚂蚁好像变得聪明起来,不想原先那样硬要冲破画线了。蚂蚁也没有了原先的嚣张和得意。在圈子里徘徊,沉着镇定的寻找着出口。
我们把圈子慢慢的缩小,蚂蚁好像再也受不了那樟脑球是气味了。好像在苦苦哀求道:“求求你们放过我们吧!我们实在是受不了了,刚才是我们太嚣张了…”最后我们把圈子缩小到比1角钱硬币还要小,蚂蚁不再徘徊了,躺在地上一动不动了。蚂蚁也许是太累了,再加上樟脑球的气味,实在受不了,所以它们就离开人间了。
蚂蚁的试验告诉我们:科学无处不在,只要你是有心人,你就会发现科学就在我们身边。
2.我在公园的草地上发现了一支队伍。这支队伍走成了一条弯弯曲曲的小路。这是什么呢?我趴下去一看,噢,原来是一支蚂蚁队伍。它们正忙碌着呢!有一群蚂蚁从洞穴里搬出泥土,另外一群蚂蚁却往洞穴里运粮食,还有一群蚂蚁正来回穿梭,好像是在指挥其它蚂蚁干活……
出于好奇,我拿出一个纸da杯,将一些矿泉水倒进了纸杯里,随手抓了几只蚂蚁放了进去。面对着这突如其来的“洪水”,这些蚂蚁惊慌失措,在水中拼命地挣扎,触角不断地摆动,好像在发出求救信号。短暂的慌乱过后,蚂蚁们好像不再害怕了,它们将腿伸开,拨动着纸杯中的矿泉水,犹如在划动着船桨。渐渐地,有几只蚂蚁聚拢到了一起,它们仿佛在商讨着逃离“洪水”的办法。蚂蚁们一边商讨,一边摇摆着触角发出信号,好像在告诉其它伙伴怎么逃离。最后,这些蚂蚁一步一步地游到纸杯的边沿,逃离了“洪水”。 紧接着,这些蚂蚁赶忙爬出了纸杯,排着整齐的队伍又加入到大部队里面去了。
过了一会儿,我将一块小饼干放在离蚂蚁们不远的地方。咦,蚂蚁真灵巧,闻到了饼干的香味。有一只蚂蚁首先爬到了饼干的旁边,围着饼干绕了一圈又一圈,然后爬了上去。接着,又有四、五只蚂蚁爬过来,它们也在饼干上爬来爬去,跟前面来的那只蚂蚁碰了一下触角,好像在嘀咕什么。大约过了一分钟,这些蚂蚁一起爬回到大部队的队伍当中。怎么这些蚂蚁都不吃饼干就走开了?难道饼干不好吃吗?过了一阵子,一支庞大的蚂蚁队伍来到了饼干旁边,望了望比自己身体大了几十倍的饼干,它们似乎在担心能不能搬得动。过了好久,这些蚂蚁个个全身不停地在摆动,仿佛在做热身运动。然后,蚂蚁们纷纷钻到了饼干的下面。喔,偌大的饼干竟然给蚂蚁们齐心协力地扛起来了。看着蚂蚁们步伐一致地把饼干一步一步扛回洞穴,我真是感到惊讶,原来集体的力量是那么强大,难怪俗话说——“人心齐,泰山移”!

今年暑假,我发现了蚂蚁的生活习性,为此我感到很高兴。
事情是这样的:在一次偶然的机会我看见有许多蚂蚁在“扛着”一只蚂蚱。这引起了我的好奇心。于是,我就仔细的观察起蚂蚁来。我发现蚂蚁的洞口比较小,周围有一些细沙,有许许多多蚂蚁在进进出出的忙碌着,可见蚂蚁是群居生活。
为了证明蚂蚁靠吃什么为生,我便从家里拿了一块糖、大米和菠菜。把这些东西放在离洞口比较近的地方。一只小蚂蚁最先发现食物,它一一爬到每个食物上,又爬下来跟附近的小蚂蚁碰了碰触角,然后就回到了洞里。不一会儿,来了许多只蚂蚁,黑压压的一片,它们齐心协力抬着糖块和大米一起地瞳回洞口,却不碰菠菜。看!它们搬不进去了,因为糖块太大而洞口很小,它们想出了一个巧妙的办法,围着糖块开始啃,用了很长时间才把糖块啃成一小块一小块的,然后再一块一块地搬回洞里。通过这个实验,我知道了蚂蚁是用触角辨别食物,喜欢吃甜味的东西和农作物,由此我断定蚂蚁是害虫。蚂蚁对人类的危害很大。如果蚂蚁在大坝上“安家落户”,那可惨了,人们不是常说“千里之堤,毁于蚁穴”吗?更不用说那专吃树木的蚂蚁和食人蚁了。洪水一来,大坝就会被冲垮,要危害到多少生命,损失多少财产呀!那专吃木要头,给大自然的树木带来危害的白蚂蚁,还有那食人蚁,对我们人类更是一大威胁。
通过这次对蚂蚁生活习性的发现,对我的启发很大。今后,我们要经常留心周围的事情,做到一名学科学、爱科学、用科学的好学生。运用科学知识去解决问题。
