海龟在大家的印象中,应该是笨重而强壮的动物。

然而,你可能还有不知道的呢!

海龟在陆地上十分好欺负,但到了海中,它们就成了捕食者。

它们有着流线型的身体和健壮的“腿”好像是专门为当“旅行者”做的准备,身上的硬壳和尖尖的头,好似是用来扛、挂行李的一样。

海龟可是一位旅行者,它们是出生在沙滩上的,而不是在海里,它们的妈妈在沙窝产下海龟蛋后就不会再回来了,这些小海龟独自生长。

刚从沙窝爬出来的小海龟,要想走回大海,那可有千难万险呢!它们一路上会被鸟类捕食、被人们捕捉,甚至会因灯光干扰,将方向弄错。

有一些可爱的小海龟,一直不折不挠,最终回到大海生存下来。

我觉得,能成功爬到水中的龟,已经是精英了!看,你的脑中有没有几只小海龟在沙滩上爬行的画面呢?

终于,小海龟入海了。

很快,大多数的海龟都长大了,有几十厘长,几十千克重了。

它们一边成长一边学习,如何睡觉、捕食等。

其中捕食最有趣。

它们有的追着猎物游,有的张着嘴,让好奇的鱼儿进来。

啊呣!海龟的晚餐来了!

随着海龟慢慢长大,到了该当妈妈的年纪,它们会回到自己出生的地方,产下七八十个卵,然后,让小宝宝们在沙窝里沐浴着阳光,自己慢慢爬回海中继续生活。

你们是不是很期待新的小海龟诞生呢?那就不要打扰,静静地等吧!只有好好保护,新生命才能绽放。

一次偶然的机会,老爸从超市买回来一袋“重庆怪味胡豆”,乍一看这种食品的名称,我就对“怪味”这两个字产生了强烈的好奇心:什么样的味道才是怪味呢?为了尽快得到答案,我便迫不及待地打开包装袋,飞快地拿了一颗放在嘴里细细地品尝,味道果然不同凡响。从此我就迷上了这种味道特别的风味食品。

胡豆也叫蚕豆,是重庆的特产。

重庆怪味胡豆具有特有的工艺、独有的风味,集麻、辣、甜、咸、酥为一体,堪称一绝。它颗粒壮似桑椹,色泽滋润,香甜酥鲜美奇特,麻辣咸舒适爽口,品赏时除直观感外,还有美妙的想像之味。奇趣多多又相得益彰,因此得名怪味。

重庆怪味胡豆还有健脾开胃调理,学生膳食,夏季养生调理,便秘调理,清热解毒调理,益智补脑调理等功效,还荣获“99重庆市最佳食品品牌”、“98中国食品工业协会推荐品牌”、1996年中国国际食品博览会“国际品牌精品”、1995年中国·成都国际食品精品,食品机械包装设备博览会暨。

怪味胡豆的制作流程非常精细——把鲜蚕豆去皮、摘芽、洗净,煮熟后捞起,控干水分,用植物油加盐、料酒炒几下蚕豆,再加入糖、辣椒面,再炒几下,最后放入味精、花椒粉、香油,炒匀后一盘重庆怪味胡豆便闪亮登场了。

怎么样,听了我的介绍,心动了吧!快去买一袋尝尝吧!

在我家书柜里,有一个极其精美的相框,里面有一张红色的剪纸。剪纸呈“福”字型外框,这张剪纸虽然不大,但做工极为精细,让人无可挑剔。这张剪纸是外婆过年时送给我的,充满了节日的喜庆,我把它珍藏了起来。

仔细一看那剪纸,一个胖乎乎的大头娃娃,花瓣一样的头发,细长而浓密的眉毛,大大的眼睛水汪汪的,还有一个小鼻子。他穿着一件花衣裳,上面绣着菊花的图案,两只袖子上还有几只凤凰。他那馒头似肉乎乎的小手中拿着一只晶莹剔透的玉如意,开开心心地笑着,喜着。我自己给它编了一个故意:从前,有一个聪明机智的小男孩,出生在一个穷苦农民家,一次,小男孩种了一朵荷花,可到了第二天,荷花竟变成了一只闪闪发光的玉器,小男孩开心极了。“有它,我能去换一件暖和的衣服。”话音刚落,霎时间,玉器闪闪发光,光线越变越强,在一阵耀眼的光束之后,一件棉衣穿在小男孩的身上,小男孩乐极了,抱着如意又蹦又跳。给它起名为“如意”。从那以后,小男孩用它得到了自己想要的东西,生活富裕了起来。

古人把剪纸当作喜庆的象征,每张剪纸都有着自己的寓意,保佑人们幸福美好。

每个人都有自己喜欢的一种风味食品,我也不例外,我喜欢的风味食品是潮汕牛肉丸。

在我们潮汕地区,潮汕牛肉丸是最有名的风味食品之一。它圆溜溜的,大如汤勺,丸味香滑,细嫩松脆。其实想吃到香喷喷的牛肉丸,就要准备好材料:牛霖,肥肉、鱼露、潮州薯粉,虾米,金银蒜,沙茶酱,胡椒粉,麻油各适量。再将牛肉,肥肉切小块,虾米洗净发好,切碎,将所有原料倒入高速搅拌机中打成肉胶,唧成丸装,入70度开水中,慢火煮至水开,丸即熟,新鲜牛肉丸就会使你垂涎欲滴。

然而我最喜欢吃的是牛肉丸火锅,首先先煮好70度左右的开水,往里放些油,再把牛肉丸放入锅里煮,放入汤料,不一会儿,一锅香喷喷的牛肉丸火锅就会出现在你的眼帘!让你大饱口福!

味道鲜美,口感爽脆的潮汕牛肉丸将以它无以伦比的美味吸引着更多外来客!

瞧!这就是我最喜欢的风味食品——潮汕牛肉丸!

白色的毛,短短的尾巴,长长的耳朵,这到底是什么动物呢,没错,它就是兔子,。

兔子虽然不如森林之王老虎凶猛的,狮子威风,但它却很有自己独特的魅力。

它平时很安静,也不乱叫,摸起来也很舒服。

它的毛软得像一团白缎子,又白又长。

它的身上就像穿着雪白皮袄,在灿烂的阳光照耀下,像一堆闪闪发光的白棉团,真是漂亮极了!

圆滚滚的尾巴躲在绒毛里,不仔细看,还不容易被发现,兔子的尾巴不仅小,而且还很圆,就像一个又小又圆的网球。

小白兔的头很小,两只长长的耳朵像两把大扇子插在头上,只要有一点动静那对耳朵就会测出是否是危险,如果是,它就会快速地逃走。

最有特色的东西就是小白兔的眼睛,它的眼睛特别漂亮,有小玻璃球那么大红光四射,就像一个晶莹剔透的红宝石。

小白兔吃的`东西尤其挑剔,一定不能乱吃,除了可以吃干草以外,还可以吃兔粮、萝卜叶子、胡萝卜、人工饲料。

小白兔吃的干草一定要是新鲜,最好是春雨过后,湿润时草。

如果草很老,会引起小白兔肠胃不通,一般吃完人工饲料或别的很***食物后,也可以喝点水,这样就不会噎着了!

兔爸爸和兔妈妈每两个月会生4至10只兔宝宝,照这样计算,一年大概能生一百到两百只兔宝宝,真是个超级大家庭呢!兔妈妈生兔宝宝前,一定要给它喂点草噢,不然兔妈妈太饿了就没有力气生小宝宝了!

这就是可爱,美丽的兔子,你们想不想也来一只呢?
