[描写花和树的英语作文

我最喜欢的动物，牠有一条毛茸茸的长尾巴，膨膨松松的像鸡毛杆子，有一个娇小又柔软的身体。牠的身体虽然娇小，但灵活的四肢，让牠能够在树林间飞快的穿梭，你知道牠是谁了吗?对!没错!牠就是可爱的——松鼠。

记得有一次，我们全家利用假日到中山林游玩，当我们嘴里哼着歌，迈着轻快的脚步，不知不觉的走到一片树林里时，因为那时刚下过雨，所以不时有水滴落到我们的身上，整片树林是非常的寂静，耳边听到的不仅是清脆的鸟叫声，还有昆虫「唧唧」的声音。就在这个时候，一个小黑影跳了过来，拿走了我刚从地上捡拾在手上的小果子。哇!被牠这么一拿，我整个完全傻了眼，竟然被眼前的景象给吓呆了，等我回过神来，仔细的看清楚后，才知道原来是一只小巧可爱的松鼠，牠正站在树枝上吃着那颗小果子呢!那可爱的模样，真让我感到既心疼又喜欢。我再回想刚才牠碰触我的那一剎那，那条毛茸茸的尾巴，真是无法形容的柔软啊!

有了那次的体验后，每次当我到树林的地方时，我都会特别仔细的寻找牠的身影，希望能再看到松鼠的可爱模样。如果看到电视里播放有关动物的节目时，我也会特别的留意，看会不会再看到牠，因为我实在太喜欢牠了。

我觉得这世界上的动物，并不一定全是凶恶残暴的，像老虎抓兔子、蛇吞老鼠、……，牠们所以会那么残暴，那全都是为了填饱牠们饥饿的肚子，那是动物求生存的本能啊!如果大家都能这么想，那动物就跟人类差不多了，并没有想像中的那样可怕啊!

Animals are friends of human beings. Most of them are lovely. I like giraffe the most. They are very tall and have many brown spots. They have very long necks, so that they can eat the leaves in high trees. Giraffes are gentle and lovely. They are friendly to people. When I go to the zoo, I always look at them. They move slowly. I can’t keep it as a pet, because it’s so huge. It’s a big pity.

动物是人类的朋友，大部分的动物都很可爱。我最喜欢的是长颈鹿，它们很高而且又很多棕色斑点。它们的颈很长因此可以吃到大树上的叶子。长颈鹿温驯可爱，它们对人类很友善。当我去动物园的时候我总喜欢去看它们。它们动作缓慢。我不能把它当宠物因为它太大了，这有点遗憾。

As we all know,animals are our friends.I like every animal.But I like dogs best.Dogs are not only very lovely,but also very helpful.Thats why we all feed dogs at home.I often share happiness and shorrow with it, which belongs to me three years ago,called"Betty".In other words,we should treat them as our real friends.Do you agree with me?

我们都知道,动物是我们的朋友。我喜欢所有的动物。但我最喜欢狗。狗不仅是很可爱,但也很有帮助。这就是为什么我们都喂狗在家里。我经常和它分享快乐,我三年前称它为“贝蒂”。换句话说,我们应该善待我们的真正的朋友。你同意我吗?

My grandmother is sixty—two years old。 She is healthy so that she walks around often。 In the morning， she goes to buy food in the market early。 There are several old grannies going with her。

In their opinion， it’s a kind of exercise， because walking is important to their health。

Besides， my grandmother is very active and easygoing。 She makes many friends near my home， from her peer to the little babies。

She always laughs and makes others happy。 I think my grandmother is so lovely that I want to stay with her。

最近， 我家新添了两位新成员——两只可爱的小仓鼠，它们俩还没有我的拳头大。瞧!我还给他们布置了 一个新家呢：这座小房子是双层的。第一层的地上铺着一层厚厚的木屑，一台小巧玲珑的跑步机旁，是通往二楼的 滑梯，滑梯的右下方是一个迷你版的小水壶和一个红色的小餐盘。第二层有一座超小型的木屋，屋顶是咖啡色的， 其余的都是白色，整个就像一块巧克力蛋糕。

我给它们分别取了一个名字，“小金子”和“小银子”。“小金子”全身雪白，眼睛是红色的，像两颗红 玛瑙;“小银子”全身黑白相间，眼睛像两颗黑芝麻。他们的耳朵、鼻子和“手脚”粉嫩粉嫩的，看上去很是吸引 人。它们的身体像两颗小绒球，圆圆的，毛茸茸的。它们的爪子非常奇特：前爪有四个，总是缩在胸前，后爪有五 个，尖尖的，吃起东西来可方便了。又长又细的胡须从它们的嘴边冒出来，滑稽又可爱!

“小金子”和“小银子”很懒，白天不是吃就是睡。每当我把食物放入它们的小餐盘里时，它们立马精神 振作起来，争先恐后的吃着盘中的食物，所以它们长得圆嘟嘟的。

到了晚上，它们要开始活动了。只见“小金子”快速地从滑梯上窜到了二楼，表演它的绝活——“飞檐走 壁”。它一个敏捷的转身就从笼子这边，跳到了笼子那边。相比之下，“小银子”就要安静得多，它在木屑上来回 踱步，不知在思考什么……就这样，一个夜晚过去了。

第二天，当我再来看这两个小家伙时，它们已经睡着了，缩成小小的一团，躲在木屑里。明媚的阳光洒在 它们身上，暖洋洋的……

舅婆家养了一只狗，是公的。听妈妈说是泰迪犬，就像动画片里的泰迪熊一样。它的名字叫黑黑。我们不叫它的全名，只叫黑黑身子呈咖啡色，全身的毛又长又卷，脑袋圆圆的，身子胖乎乎的，尾巴短短圆圆，牙齿雪白尖利。

凯七警惕性很高，对待朋友相当热情。别看它成天疯玩，只要听到敲门声，或其它一丁点儿异动，不管它正在干什么，准保会一下子窜到门口，汪汪大叫。一旦得知来者是客，它就会立刻跳到客人身上温柔地叫唤，表现得很是热情。

凯七还很贪吃呢。吃饭的时候，如果不把它关起来，它就会跳到人身上要东西吃，不给他吃，它就会一直叫唤；如果把狗粮放在手上喂它，它就会一直跟着你，一步不离左右，甚至上厕所也不例外。

它喜欢球，尤其爱和玩具鸭子玩。有一次，我拿着一个小皮球，随便一扔，他便飞跑的去抢，由于速度太快，一头撞在了墙上，愣了好半天没回过神，搞笑极了。等它回过神来，我又把玩具鸭子弄响，朝他扔过去，没想到它一点不吸取教训，又去抢鸭子。我把鸭子抢过来，弄响，不扔，它又来抢鸭子。

这就是我舅婆家的狗——黑黑，它真讨人喜欢。

Yesterday had a major event, this thing let our family welcome joy. Kitten finally came back, I am very happy.
