1000篇我喜欢的小动物五年级作文
全文共 562 字
+ 加入清单每个人都有自己喜欢的小动物,有人喜欢小猫,有人喜欢小狗,哈哈,反正是萝卜青菜各有所爱。
我喜欢的动物要很多;小狗,熊猫,小鸟。。。。到那我不怎么喜欢,我最喜欢的是小猫。它那漂亮的毛滑滑的,大大的眼睛承托这个中等大小的脸,可爱极了。它叫起来,温柔好听,像灵泉一样流露出来。
它心情好的时候,会在你的脚下走来走去,那滑滑的的猫使得你痒痒的,也会用那脏脏的脚掌在你写字本上踩来踩去,使得你想揍它一顿,可以见它那可爱的表情会让你不忍心下手。心情不好的时候,理也不理你一顿,就算你怎么叫,都不采理你。它想玩就玩,一玩就玩到天昏地暗,它不想玩的时候,都会乖乖的在它的窝里睡觉。猫就是这样,让人难以猜测,也让人觉得它,懒。
它最喜欢玩毛线,一玩起来把什么都不放在眼里;它也最喜欢吃鱼,吃起鱼来,都会发出咕咕的声音,好像在说;好吃好吃。猫也会挑食呢。给它肥肉吃,它不吃,非要有瘦肉或鱼它才吃;给它球玩,它不玩,非要玩毛线才行。这也让人们特别讨厌。
虽然它神秘莫测,贪吃又贪玩,但是有一件事它可是高手呢!
每到晚上,那些可恶的老鼠找东西吃,只要猫看见了,紧盯着老鼠,找到时机,一扑,一抓,就把那老鼠捉到手了,这对它来说,那就是张飞吃豆芽小菜一碟这也就是人们让小猫的理由了。
猫神秘莫测,贪吃又贪玩,又会捉老鼠,让人们又讨厌又喜欢。
我就喜欢小猫,你喜欢吗?

篇3:我最喜欢的动物英语词

+ 加入清单Perhaps, everyones heart has their own favorite animals, small to cats, dogs, big to elephants, pandas, giraffes, but, I like animals or insects, small to not see dont see, it is the most easily neglected but a large number of ants.
The ant is a kind of like social insects, dont look at it, but it has a "strong man" title. An ant can lift 50 times more than their weight. 2 times people if can move up the weight of everything is wonderful. People who want to really dust and ants than strength.
Previously, I have heard, the ants are very united, I also saw, in the ant mouth, many ants against a live common caterpillar, thought, and the mere survival needs, hunting together, a lot of animals wolves hunt, hyenas are so common, no surprise. So many ants have thinking every day together, cant afford to infighting just strange!
Later, I saw an article, let I to small awestruck by ants. This article writes: a group of ants meet fire, they didnt panic, immediately transform into a group of formations, these can keep the queens, young ants race survival ant package in the middle, rapid rolling a ball of fire, break through in the direction of the river, outer ant ant regiment repeatedly heard burned after the burst of noise, but not to reduce the ant regiment. Obviously, this outer "ant kingdom hero" by the burning to death also dont loose fraction, courage all crack dont give up their jobs. And in a short while, ant group rushed into the river, as to the other side of the scroll, the river rose a thin layer of smoke... Any creature that has a survival instinct, small ants can in a survival situation, continue to race, choose to sacrifice myself, what a respectable!
Compared with the unity of ants, we should be ashamed of yourself. Sometimes because of the little things, and her classmates went red, shouldnt have. Originally in the world, noble and great really has nothing to do with size, strength, what really matters is strong in spirit, if we have ants so closely united, dedicated spirit, what we cant finish?
也许,每个人的心中都有自己最喜爱的动物,小到小猫、小狗,大到大象、熊猫、长颈鹿,可是,我喜欢的动物或者说是昆虫吧,小到不仔细看根本看不到,它就是最易被人忽视的却又数量庞大的蚂蚁。
蚂蚁是一种喜欢群居的昆虫,别看它微不足道,但它却拥有“大力士”的称号。一只蚂蚁能搬起超过自己体重50倍的物体。人如果能搬起自己体重2倍的东西都很了不起了。人要和蚂蚁比力气可真是望尘莫及。
以前,我曾听别人说过,蚂蚁们十分团结,我也亲眼见过,在蚂蚁洞口,众多蚂蚁共同对付一只活毛毛虫,心想,那只不过是生存需要,共同猎食罢了,好多动物像狼、鬣狗都是这样共同捕食,不足为奇。这么多有思维的蚂蚁天天在一起,不起内讧才怪呢!
后来,看到了一篇文章,让我对小小蚂蚁肃然起敬。这篇文章写道:一群蚂蚁遇到火灾,他们没有惊慌失措,立刻变换队形扭成一团,将蚁后、幼蚁这些可以维持种族生存的蚂蚁包在中间,迅速滚过火球,向河岸方向突围,蚁团不断发出外层蚂蚁被烧焦后爆裂的声响,但是蚁团却不见缩小。显然,这外层被灼焦的“蚁国英雄”们至死也不松动分毫,肝胆俱裂也不放弃自己的岗位。一会儿,蚁团冲进了河流里,随着向对岸的滚动,河面上升腾起一层薄薄的烟雾……但凡生物,都有求生本能,小小蚂蚁却能在生死关头,为了种族延续,选择牺牲自己,多么可敬啊!
和蚂蚁的团结比起来,我们应该感到惭愧。有时因为一点小事,和班里的同学就闹得面红耳赤,真不应该。原来这个世界上,崇高与伟大真的与个头、力量没有关系,真正重要的是精神上的强大,如果,我们具备蚂蚁这样紧密团结,勇于奉献的精神,还有什么事情我们不能完成呢?

+ 加入清单我家小狗白雪属于古代牧羊犬,有一身黑白相间的毛,一双丹凤眼,一只是蓝色的,一只是棕色的;一双有时竖起有时耷拉的耳朵,最奇怪的是,它是一只没有尾巴的狗,我非常喜欢它,因为它是一只淘气、可爱、聪明、善战的狗。
白雪从来都不在自己家门口大小便,总是箭一样冲到邻居家门口,蹲到人家的脚垫上,痛痛快快地拉个够,让我们哭笑不得。
有一次我家的电视上放一些狗粮,它看见了,就彬彬有礼地走过来,乖乖地蹲下来,流露出听话可爱的神态,它心想:电视也能像人类一样实现我的愿望吧,可等了半天,狗粮还是无动于衷,于是它恼羞成怒,用力的扒着电视,发出奇怪的声音,它一不小心把电视的开关按扭打开了,电视里出现几个人,白雪还以为是来打它的,于是就一溜烟地逃跑了。
白雪打架的时候十分厉害,总是靠智慧战胜对方。遇到比自己小的狗,它会冲上去把人家打得落花流水,逃之夭夭;遇到比自己强大的狗,就假装做出失败的样子,忽然袭击,这样,它就反败为胜。
睢!这就是我家的小狗--白雪,相信你是它的主人也会喜欢它。

一:贪睡。在它们冬眠时,那样子真是太可爱了!它们像两只熟睡的小熊,什么东西也不吃,就算你拿出大鼓,使劲敲也叫不醒它们,它们可真贪睡啊!
二:贪吃。在它们过了冬眠之后,可就变成了两只贪吃的“小猪”。看!有时,我会喂些小虾给它们吃,它们狼吞虎咽,有时一只小乌龟会用脚踢跟它抢食的同伴,似乎在说:“别跟我抢东西吃!”可真霸道!
三:贪玩。贪玩是小朋友的特点,当然也是小乌龟的特点。小乌龟们包餐一顿,就进入了游戏环节。第一个游戏叫叠罗汉。它们中的一只乌龟爬上了另一只的背上,就这样,这个游戏它们每天会玩5~10次。第二个游戏叫爬玻璃缸。它们虽然知道自己爬不出玻璃缸,可它们每天还是爬呀爬,似乎充满了爬出去的希望。最好玩的要算带它们散步。它们东看看西瞅瞅,对外面的世界充满了好奇。有一次,我把它们放到浴池里,过了几分钟,我去看它们,发现少了一只乌龟,我找来找去,终于在洗衣机吸满找到了它,它可真调皮啊!
我爱我家的可爱的小乌龟!

+ 加入清单我最喜欢的动物就是小狗啦!每当我看见小狗的时候都会被他们所吸引,这是为什么呢?因为他们的样子非常可爱。有的毛卷卷的,像烫过的一样。有的耳朵大大的垂在两边,像戴着帽子的小老头.。有的浑身雪白雪白的,毛茸茸的,走起路来就像一团绒球滚来滚去。有的活泼好动,一刻不停的在主人前后跑来跑去,像一个调皮的小男孩。有的热情好客,一见到人就“汪汪”地打招呼。还有的看样子很凶,其实很老实,一直乖乖地跟在主人身后……
我也非常想要养一条小狗,但妈妈怎么也不同意,弄得我很扫兴。幸亏我的同学那里有一条非常可爱的贵宾犬,每个星期日,在等校车的时候都可以看到它。我跟它握握手,摸摸它的小鼻子,他也用舌头来舔舔我的小手,我们就这样成了一对好朋友。
我长大了以后一定要养一条属于自己的小狗。

每次放学回家,小花猫蹲在大门口等着我,看到我回来,它就摇着尾巴,仿佛在说:“小主人,你终于回来了。”回家后我给它喂吃的,看着他贪婪地大口大口地吃,我很高兴。吃完后,它就躺在院子里享受阳光。
有一次,它的脚好像被什么东西粘住了,我把它抱在怀里,仔细地检查什么也没有发现,还是妈妈的眼睛厉害,一眼就看到脚底下的玻璃渣子了,妈妈仔细地帮它拔了出来,它感激地望着我们,好像在说:“谢谢你们了!”,这只猫可真有灵性。

我把小蜗牛们带回了家,放在盒子里,仔细观察一下。它们的壳是棕色的,薄薄的硬硬的,像一个个小房子似的,壳上面的花纹是一圈一圈的。它们的身体是乳白色的,软软的。蜗牛有两对触角,它们的眼睛长在后一对触角上,两个触角向前伸着,特别灵敏,只要轻轻一碰,立刻会缩回去。它们白天睡觉,晚上起来吃食物。它们最喜欢的是大白菜,别看它那像针尖一样小的嘴,里面却有26000颗牙齿,是世界上牙齿最多的动物,所以吃起东西来可快了!
我刚把蜗牛带回家时,妈妈很不喜欢它们,觉得它们生活在泥土里很不干净,我就用一个塑料盒盛了一些水把它们放了进去,不一会儿,小蜗牛的触角慢慢伸出水面,它们俩小心翼翼地往上爬,爬的好慢啊。它们爬过的地方留下了黏液。我用铅笔轻轻触碰它们的身体,蜗牛的两对触角就像害羞的小女孩,立刻缩到它们的房子里。妈妈渐渐喜欢上了它们,并用大白菜做了一个小房子。第二天一早,我去看它们时,怎么也找不到,小朋友们,你们知道我的小蜗牛躲在哪里吗?原来呀,它们藏在白菜房子里呼呼睡大觉呢!
小朋友们,你们喜欢我的小蜗牛吗?

小白兔的眼睛非常奇异,它是红色的,好像一颗亮闪闪的红宝石。我问妈妈:“小黑兔眼睛是黑色的,小灰兔眼睛是灰色的,小白兔眼睛为什么却是红色的呢?”妈妈对我说:“小黑兔身体有黑色素,小灰兔身体里有灰色素,而小白兔的身体里没有色素,那是它血管的颜色。”
我听了以后恍然大悟,没想到小白兔的身体里还有这么大的奥秘!
我觉得小白兔的尾巴是最有趣的,它就像一个小棉团一样。它真像传说中那样,乌龟把它的尾巴咬得只剩下了一个毛茸茸的小圆球。
小白兔它什么都怕,有时候假如你扔一片菜叶,它也要躲一躲,等到它确定你走后才敢回来吃。可是他又是那么的勇猛,有时候闯一闯树丛,甚至邻居家的猫来了,它也敢斗一斗。
小白兔吃饭的时候 最有趣。见到了合它口味的蔬菜,它便一下子冲到那里去,张开自己的三瓣嘴,一点一点地品尝着可口的蔬菜。当你仔细观察,你会发现,它吃饭时,那奇怪的三瓣嘴和那只有几根的胡须一颤一颤的,那样子可真有趣。
它也非常淘气,假如你把它放在草坪上,一会儿,你回来找它的时候,它就已经无影无踪了。可是,正当你焦急万分的时候,它又从树丛后面跑出来,扑到你的腿上。
小白兔可真是太惹人喜爱了。

小黑吃东西可挑了,它经常到我们家,向我们要肉骨头吃,给它一块小的骨头,它先闻了闻,之后再吃进去,然后它又吐了出来,好像在说:“这么小的骨头,还不够我塞牙缝呢,我要一块大一点的,大一点!”它抬起头看,可怜巴巴地看我,还摇着尾巴,又好像在说:“求求你了,”我只好给它一块大点儿的肉,它高兴地叼着肉到旁边去吃了。
小黑有一点非常可爱,每当它吃完饭,去休息或是散步的时候,就让人不自觉地发笑。吃完饭,小黑就跑出去散步,之后它从走路变成了跑步,越跑越快。然后它自己跑累了就找地方躺下来休息,没过一会儿,它的肚子又咕噜咕噜地叫了,估计是跑步跑的肚子又饿了,它起身又去寻找吃的。
这就是外婆家的小黑,我的好朋友,虽然外婆那个村里有许多狗,但我最喜欢的就是小黑。

如果你问我:"你最喜欢的动物是什么?”那我告诉你,是茶杯狗,它可可爱了,你要是摸了它,它会非常黏人。
它的皮肤白白的,就像天上白白的小云朵;它有一对水汪汪的眼睛,它还有鲜红的鼻子,好像一个小樱桃;它的嘴巴好像一个小月亮。
以前,我买了一只茶杯狗,我给它取名叫小月。每次它饿了的时候,都会叫我把杯子拿下来,把狗粮放进杯子里,每天四次,前三次每次十克,最后一次三克。每天它吃完一次,都会来找我一起玩;它每次脏了的时候,我会都帮它把水放好,把它抱到脸盆里洗澡;我写作业的时候,它总想看我写作业。
茶杯狗虽然寿命很短,但是非常粘人。
