我家有一只小狗，名叫点点，今年三岁，毛色是浅黄色的，非常讨人喜欢，点点的鼻子黑黑的，长得及小，它天生有一种傲慢的性格。

点点是一只金毛。还记的2007年冬天，正下着鹅毛大雪，它的母亲把它生下来，一个月以后我去姥姥家把它抱了回来，但它分外的小，它就是两斤左右，点点在我家生活了一年左右，因为我家没有黄土，点点的大小便也成了一个问题，无奈之下妈妈不得不把它寄存在姥姥家，点点刚走的的那几天，我无时无刻不在想它，干什么事都无精打彩，时间久了，我也渐渐淡忘了。

至从有一天，妈妈说：好久没去姥姥家了，今天去看看吧，这使我猛的想起了被我遗忘的好朋友点点，吃过午饭，我们去了姥姥家，一见面，我还差点没有认出，当初像“豆芽形”的小狗，现在却长得又粗又高，看起来威风凛凛的，鼻子上也有一点淡淡的红色，显得格外精神。

在回家的路上，我想了许久，为什么当初的小狗到了姥姥家就长大了?也吃胖了呢?我想是因为姥姥家的饭很合它的胃口吧。呵呵，我家的小点点可爱吧。

保护动物初二英语作文二：How to protect the animals？

Animals are our friends.But how to protect them? government is working to protect all animals in danger,and has made lots of plans to save animals. On the other hand, we shouldn’t eat wild animals.We should keep them away from our dinner. That way,there will not be wild animals on sale. I think the hunters and killers will become fewer and fewer.

Last, we should protect the environment.We should stop people from cutting trees down. Without trees, wild animals will lose their home. And we will lose our animal friends. All of us should try our best to protect animals.

We need to protect animals better.We should give them fresh water to drink.We should make the forests bigger for animals in danger to live in.We should advice people not to kill animals beacause they are our friends!

保护动物初二英语作文三：Save the Wild Animals

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.

In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.

Only if we human beings take some drastic measures can wild animals be preserved.

保护动物初二英语作文四：Protect Panda

People want to find a home for them, and recently, they have set up a nature park for them in Sichuan Province,which is called "Pandas Home. "There pandas can enjoy their life happily. There is a bamboo forest near the Pandas Home. So the pandas can find bamboos easily which they like to eat very much. .

Because pandas are well protected now, the number of them is increasing every year. We hope that one day we will have enough pandas to set them free and let them live in the wild again.

Pandas are good friends of man. Man should try to protect them and ]et them live in the way they like!

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。

在与人类交往的关系在历史中是最具有戏剧性的。无论是从悠远的传说，还是历历在目的现实生活，它都在人类社会中充当着非常独特的角色。它的名字就叫做——狗，没错，现在，人与狗已经相濡以沫，建立起最深厚的情感纽带，共享忠诚、眷顾、依赖与信任的伙伴关系。狗也是我们身边最熟悉的动物。

我爷爷家就有一只小狗，它长着一双黑亮亮的眼睛，一只又湿又黑小巧的鼻子，还有一对尖尖的耳朵，总是竖在那里，使它显得格外的机灵。它长得胖胖的，也不是太胖那样;四个小腿儿就像四根火腿肠;它的小尾巴一直摇个不停;它是一只黑白相间的狗，它的身上黑一块儿的，白一块儿的，头也是黑色的，但尾巴却是白色的，特别可爱。因此它的名字叫做黑白。

有一次我去爷爷家玩的时候，突然，好像有什么东西拽着我的裤腿。我吓了一跳，往下一看，原来是爷爷家的那只小狗。它那双又大又黑、看上去非常有神的眼睛望着我，好像在说：“我一个人闷得慌，和我一起玩，好不好，求你了!”我看见它这么可爱就忍不住离开房间，来到外面，和它一起玩。我捡起一根塑胶骨头随手一扔，这可是它最喜欢的玩具。只见黑白用它那水灵灵的眼睛往空中一看有一根骨头从它眼前飞过。于是，它连忙跑到骨头前用它那坚硬无比的牙齿咬住骨头把它叼到我面前，我就再扔，但每次它都能很快的把骨头叼回来，乐此不疲，直到我不想扔了为止。过了一会儿，小狗突然“汪汪汪”地冲着我叫起来，我不明白怎么回事就跑去问哥哥。哥哥笑着说：“肯定是黑白饿了!哈哈!”哥哥连忙走过去把它最喜欢的肉拿了过来，放到地上，只见它如同猛虎般扑过来，狼吞虎咽的吃了起来，不一会儿，就只剩下一块骨头了，真可爱。

狗，真的是一种充满灵性的动物，是人类的好朋友，它对我们忠诚，然而它也依赖着我们。
