有一回,妈妈带我上姥姥家去,路上我看到一条小。我见这条小狗非常可爱,就从妈妈的车上跳下来,慢慢走到小狗的身边。这时不知从哪里走过来一个人,她问我:”这小狗是你家的吗?”“是啊!豆豆走吧!”我脑子灵机一动,想出了个名字,随口就说。

望着那个人远去的背影,又看看这只小狗,我想把它带回家,因为我太喜欢这只小狗了。

我边往姥姥家走,边回头瞅着小狗,招呼它和我走,可是它只是望着我,就是不和我走。我便假装慢跑,边跑边回头,小狗以为我和它逗着玩,就慢悠悠地跟着我跑过来了。

这时不知从哪里又出来一个大男孩,他问我:”这小狗是你家的吗?”我冲他点点头,假装真的似的。可是那个男孩就是不信,还和又不知从那冒上来的一个阿姨说:”妈妈,这不是谁谁谁家丢的那条狗吗?”我有点急了,眼看就要成功的事了,不能就这样白白泡汤了。我大声说:”不是!”他们看我这样着急了,就相信了我。我便带着小狗往姥姥家走去。

我害怕小狗再从我身边走开,边走边想办法。我看见路边有一家抻面店,便过去向店主要了三块小瘦肉丁。我先扔给小狗一小块,让它看看我手里还有两块肉。然后往前走。小狗吃了一块以后,就摇着尾巴跟着我小跑起来。我带着它走到姥姥家的楼口,让它跟我上楼。看着他一跳一跳地跟着我上楼梯,我真高兴,又给了他一块。他香喷喷地吃下去,摇着尾巴又跟我走,一直上到姥姥家的门口,等姥姥打开门,小狗跟我进了屋,我才把最后一块小肉丁给了它。我赶快关上门,这条不是我们家的可爱的小狗就被我用计策带了回来。

虽然我很快就送还给为丢狗着急的李奶奶,还是觉得它带给我难忘的快乐。

Quiet warm summer out of the people in the world, the arrival of autumn quietly, summer is not sentimentally attached to this world, because he will come back, however, summer is the best season in my mind, the most beautiful in the summer.

Summer is hot and lovely season, people on the golden beaches of the foot up as soft as snow, blue and sometimes playing pretty deep sea spray, like a soft blueberry jelly, sometimes obvious, sometimes seems like a child playing hide and seek The hide.

Summer grass is always warm sun shining, the sun is particularly bright, some people also like to eat cold summer ice cream.

In the summer season the children who always like to go to a distant village from urban life, always like to sit outside their own thatched shack sun, eat watermelon, summer in the country, like a trace of the cool wind blowing over the side, and exceptionally cool summer countryside, in the clear brook clear slapstick kids in a small stream thorough pants rolled up, cheerful name of water fights, the slightest cool, the body is all wet.

篇10:描写夏天动物的段落

全文共 2584 字

1、夏天是一个浪漫的诗人,它一面吹着软绵绵的南风,一面谱出新曲,让人沉醉其中,幻想更多的新境界。

2、夏天的中午,万里碧空中飘浮着朵朵白云。这些自云,有的几片连在一起,像海洋里翻滚着的银色浪花,有的几层重叠着,像层峦叠蟑的远山,有时 在一片银灰的大云层上,又飘浮着朵朵大小不一形状不同的云朵儿,就像岛屿礁石上怒放的海石花。再看那太阳,如同熊熊燃烧的火焰。有时,它自己似乎也感到炎 热,想躲进云层去寻求阴凉。但更多地是自己在那里豪迈地燃烧着,向大地倾泄着过量的光与热,使路边的白杨叶与田里的南瓜秧无精打采地下垂着。

3、草丛中,蛐蛐撕着嗓子唱着歌;池塘里,青蛙在伞似的荷叶上为蛐蛐伴奏着。粉红色的荷花现在不再像羞答答的小姑娘了,你看它摇摆着身子,露出那张笑脸,缓缓跳起优美的舞蹈。池塘边的小花也被这美景迷住了,宁愿走出自己美好的梦境,来感受夏天的气息??

4、当夜色变浓时,人们都回家了。此时,辽阔的田野早进入了梦想,那翡翠般的禾苗,那崎岖不平的田埂,那散发着宜人芳香的小花,在这温馨的夏夜里也闭上了朦胧的睡眼,在风儿轻柔的吹拂下,在青蛙欢乐的伴奏声中做着香甜的梦。

5、夏姐姐把火红的长裙铺在地上,大地立刻就变得生机勃勃:一朵朵花儿竟相开放,它们在阳光的照耀下梳妆打扮,向别人展现出自己最美丽的一面, 好像在开选美大赛呢!一只只蝴蝶蜜蜂围着那些五彩缤纷的花儿转来转去,好像在比谁的舞蹈跳得好看呢!各种各样的小草使劲的往上钻,小心翼翼地探出头来;各 种各样的树木长得枝繁叶茂??

6、夏天最美最凉爽的时候在夜晚。每年只要一到夏天,我就盼望快点到夜晚,因为白天热得难以形容。可是夏天白天最长,盼了好久好久,才盼来夜晚。

7、雨渐渐大了,云渐渐地将原本皎洁的月亮遮掩着。使天空显得更加暗淡。这时的我仿佛已经进入了另一个世界,大脑也已被这清凉气息所清洗。路旁的骄树,也被今晚这场雨所屈折。原本炎热寂静的夏夜也被今晚这场雨所打破

8、夏天是多姿多彩的,沉静的是湖蓝,纯洁的是乳白,高贵的是米黄,热烈的是大红,典雅的是银灰,庄重的是墨黑??缤纷的色彩把温煦的夏日画满了。清雅的雏菊馥郁的郁金香娇艳的山茶花妖娆的牡丹??

9、夏之使者慷慨地赠送给了她们夏之舞衣----由白到粉,又到深粉,颜色过渡的自然让你看不出一点瑕疵,却又真真切切地让你感觉到了它的融合,不愧是吓久违的杰作之举啊!一缕缕阳光落在上面,使荷花们更加富有生机,那么优美,那么自在!

10、池塘里,告别了苞蕾的荷花,绽放着清丽的笑靥,在轻风拂送下,舞动着叠翠的裙裾,婷婷的妩媚着矜持的身姿,凝雾噙露着似若一婉约的女子在 轻轻呤诵"掉拂荷珠碎却圆"的诗句,隽秀的枝杆无不在向你展示着夏的风情,不由得让你在赞叹那绝佳的韵致间。于蓦然回首中,已是"接天莲叶无穷碧,映日荷 花别样红了"。

11、窗外的树木生长的格外苍翠茂盛,夏日的阳光像一个个调皮的小精灵在树梢跳舞,欢 笑嘻嘻笑嘻嘻系快的曲调,在树下投出斑驳的影子,也跟着动起来。看到一大片开的鲜艳的花儿,颜色张扬,如同莫奈随意画上的大片颜料一般。

12、夏天是一个可人儿,它使我们倘徉在蔚蓝的水面上,甚至连小鸭子也玩的不亦乐乎。夏天的早晨,迎着微风风向大自然走过去,是多么清静,美丽,使得这一天又充满了朝气。夏日黄昏最诗情画意,它代表着光辉灿烂的希望,它不像冬日黄昏消失了倩影。这是仲夏

13、湖面很静,静得像一缎色的丝绸。一缕缕阳光轻抚着水面,使人觉得无比的温暖。偶尔会有一阵阵微风吹过,划过水面,泛起层层星星点点的波纹。

14、静静地,走在树木中间的小路上,毫不意外地听到了蝉的鸣声,使原本闷热的夏天变得更加烦躁,心里怎么也不能安定下来。路上并没有太多的人,大概是因为天气炎热而不愿出来吧。放低太阳帽,我就来接受阳光的沐浴吧。

15、树木被太阳晒得往下垂了,仿佛一群挨了批评的小孩,垂头丧气地耷拉着脑袋。池塘里的水,似乎进入了梦境,宁静安闲,像正在做一个清澈透明 的梦,梦见自己拥抱着蓝天白云,梦见池塘里的鱼儿在蓝天白云上游来荡去,梦见池塘四周的花木也进入了梦乡,梦见池塘岸边的人们总是醒着,总是忙着,总是在 寻求什么??

16、夏日的绿,在天地间挥毫泼墨,在蓝天白云下,描绘着一幅幅多彩多姿的画卷。映入眼里的或墨绿,或清绿,都完全地脱了鹅黄的底子,它是这般 的葱茏和葳蕤着,不再浅薄不再稚嫩,浓浓的把生命的层次极尽展现。它充满激情地吸纳着烈烈的阳光,悠悠的呼吐出纯纯的气息,让你在这样绿的庇护中,神清气 爽,尽享清凉。

17、不知不觉中就到了黄昏,我已经在荷岸站了几个小时了。彩霞满天,也是只有站在这个角度。才能看见一个橙红的太阳一跳一跳地跳进了大山之中,也只有在这个时候,才能清楚地看见远山那优美的轮廓。这真是一幅难得一见的美景啊!

18、夏天是绿色的。不信你走进我们的学校看看,你会发现校园被一片绿色笼罩了:大树小树绿绿的,草地也是绿绿的。榕树高大挺拔,抬头仰望,一树鲜绿的叶子在阳光下闪着光,展现出无穷的生机。

19、夏天是一年四季中最炎热的季节,也是非常美丽的季节。我觉得夏季的美在于绿色,我最喜欢绿色。一到夏天,绿色无处不在。碧绿的小河,绿茵茵的草坪,嫩绿的杨柳,看起来真让人赏心悦目!

20、乡间的空气比城里的空气清新多了,没有一点儿杂质,仿佛是用清水洗过的一样。荷花,荷叶,整个荷塘都随着那柔柔的晚风翩翩起舞,又增添了几许夏的独特的风味。

21、夜晚,特别的安谧静美。知了睡了青蛙也睡了。天空中,明亮的月亮像一位仙女,她给大地披上了一层银纱。那位仙女一直望着我,向我絮絮低语。在她周围,许多调皮的小星星向我眨眼。

22、夏天是红色的。唐朝诗人杨万里在诗中写道:“毕竟西湖六月中,风光不与四时同;接天莲叶无穷碧,映日荷花别样红。”你瞧,那一朵朵粉红色 的荷花犹如披着轻纱的仙女在湖中沐浴。娇羞欲语,盈盈欲滴,随风飘来清香阵阵,沁人心脾。有的蓓蕾初绽;有的含苞欲放,花骨朵像火炬似的高高伸出;有的竞 相开放,露出娇嫩的小莲蓬。

23、夏天的夜色,总是挂着迷人的色彩,有点深沉却带着浪漫。天空的云朵在晚霞的映射下,五彩缤纷,幽悠的明艳着自己的美丽。那高悬着银镜似的 圆月,把那如水的清辉漫漫倾泻,在蛙鸣虫啁中,繁星调皮的眨着眼,快乐的欣赏着婆娑的树影。这时,习习的凉风便把昼日里的烦与忧轻轻的弥散开来。

A triple bacon cheeseburger seems like a heart attack on a plate.

三层奶酪咸肉汉堡感觉吃完很容易让人突发心脏病。

So how can polar bears thrive on their version, seal blubber?

那么,北极熊是如何处理这些高热量食物的呢?

Turns out theyve stocked up on genes that let them clear fats from their blood.

结果显示它们储存在遗传基因里的信息使得它们能够清除血脂。

Thats according to a study in the journal Cell.

这是根据《细胞》杂志上的一篇研究得出的结论。

Polar bears are well adapted to life on the sea ice.

北极熊非常适应在浮冰上的生活。

Up to half their body weights fat, which gives them extra insulation and buoyancy, and provides them with a ready source of energy.

几乎占它们身重一半的脂肪足以使它们保暖并且维持体力,提供给它们一种易转化的能量。

But how can an animal so fat also be so fit?

但一种动物怎么能又胖又健康?

Researchers compared the genomes of polar bears with those of brown bears, and found that polar bears have accumulated genetic changes that boost their heart health and fat metabolism.

研究人员们通过比较北极熊和棕熊的基因,发现北极熊的基因组中积累了不少有利于心脏健康和脂肪代谢的遗传突变。

One gene in particular, called ApoB, helps move cholesterol out of the blood—where it causes problems in humans—and into cells.

特别是编码为载脂蛋白B的基因有助于清除血液中对人类有害的胆固醇转变成细胞代谢。

These genomic changes happened quickly, evolutionarily speaking.

这些遗传变化从进化的角度来讲发生的十分快。

Polar bears and brown bears diverged from a common ancestor less than half a million years ago.

北极熊和棕熊都来自于同一个祖先,它们是在大约50万年前左右开始向不同分支进化。

But if that seems super speedy, the ability to digest lactose didnt spread through human populations until we domesticated cows, just 10,000 years ago.

但是如果这种变化看上去十分快速的话,消化乳糖的酶逐渐进化到人类各个种群中也还是发生在大概1万年前我们可以驯化乳牛之后。

这是自然选择力量的证明。

Animals are natural resources that people have wasted all through our history.Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way.Thousands of kinds of animals have disappeared from the earth forever.Hundreds more are on the danger list today.About 170 kinds in the United States aloneare considered in danger。

Why should people care? Because we need animals, and because once they are gone, there will never be any more。Animals are more than just beautiful or interesting.They are more than just a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice.Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly。

Luckily, some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.Quite a few countries have passed laws.These laws forbid the killing of any animal or planton the danger list.Slowly, the number of some animals in danger is growing。
