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.
这个寒假,学校布置了个作业:4—6年级每个人制作一件“科技小发明”。做什么呢?我望着窗外的雪景,突然,我想,要不做个“雪花飞舞”吧!
我准备的材料有:塑料泡沫板、大号可乐瓶、剪刀、水彩笔、吸管、牙签。
开始做了!我先将大号可乐瓶上部用剪刀剪下;再把塑料泡沫板剪成和可乐瓶上部口一样大小的圆形,上面扎一个洞;接着,把吸管短的一端插进扎好的孔,上面多余的部分剪掉;然后,把弄好的泡沫塑料板用水彩笔打扮一下,用牙签把自己想放进去的小玩意儿固定好;最后,我用剩下的塑料泡沫互相摩擦,一个个像一粒粒雪的东西掉下来。有的小球很调皮,总爱往我的衣服上、头发上、脸上、裤子上、鞋子上,我费了九牛二虎之力,终于把小球一一抓回来。我把小球装进可乐瓶里,把塑料板装好,就大功告成了!
我端详着“雪花飞舞”,希望它能给科技节做点事。
在我们中国上下五千年,其中也不乏盛世,人民生活幸福指数可能高于现在,但是对于那时环境污染的记载却几乎没有。而在近一个世纪里,尤其是最近的几十年中,环境被严重破坏,到了触目惊心的地步,人类的生存条件日渐降低,许多的生物已经绝种,大量的物种濒临灭绝,为何?
“水可载舟、亦可覆舟”这是我国博大精深文化中的一句。我认为非常有道理。最近的一个世纪,科技的兴盛,创造了无数的前所未有,但同时也带来了前所未有的大破坏。科学技术的运用发明了更多的产品,也使人类的***更加膨胀,带来了战争,于是大量开发矿产,破坏地形地貌,破坏了生物链,最终也破坏了人类的生存条件。
在我国五六十年代,庄稼所用的肥料都是有机肥,用家畜的粪便或用河道里的於泥,腐烂的草,土地的特性得到保持,但在使用化肥农药后,产生了一系列的恶性循环,土地日益酸碱化,农作物也受此影响,而这种现象要大自然用几百年的时间才能减弱。另外,河道中的淤泥日益增多,破坏了生态环境,加上工业污水使鱼儿无法生存,前些年,太湖大面积的发生蓝藻,使无锡市民得不到饮用水,也是这方面的因素。
而工业的发展更加剧了破坏环境的进度,石油和煤炭的大量开采,大量的排放和尾气产生了地球温室效应,使得全球气候产生了变化,引发了许多的自然灾害,如此长久下去,人类迟早会毁灭在自己的手中。
幸好人们发现了这种变化,许多国家在发展工业的进程中也加强了保护环境的意识。德国是一个人造森林最多的国家,在破坏的同时绿化相同的面积,从而保持了总的'生态环境。在我国,这种做法也在逐渐推广,运用科技力量,在发展中注重环保,但是只起到一部分的作用,同样,在太湖蓝藻事件中,许多的方法只起到了表面的作用,最后,放养了大量的鲢鱼去食用蓝藻,用生态平衡法则来解决根本问题。
近几年来,在我们农村,环保意识史无前例的加强了,建立了许多生态保护区,更多品种的生物回来了,在我家后面的河面上,多了一些不认识的水鸟,爷爷说四五十年没见到了,这让人感到欣慰。
所以,我们这一代人身上的使命更神圣了,责任更大了,我们要加强环保意识,提倡“低碳”生活,处处进行“节约”生活,从细节着手,保护好我们的家园,保护好大自然,保护好我们赖以生存的地球。
On Sunday morning, my parents took me to the zoo. We did not go there for a long time. Last week, my classmates told me that the zoo added some funny entertainment facilities. I was very curious. So, I asked my parents to took me there and they promised to. We got there at 9 o'clock. There were many people.
Most of them were parents and children. We first went to see the animal. I like parrots most. And then we saw the animal shows. Elephants, tigers, lions and monkeys did wonderful shows for us. People were happy, especially the children. After that, we went to experienced the entertainment facilities.
My mum was too scared to be with us. So, only my dad and I played. It was so exciting, but I was a little dizzy. However, I was very happy. It was a great day.
My favorite animal is the dog. Dogs are the most loyal animals to people.
My family also has a dog, its name is lu lu, is a male dog. It was a shish dog, covered with long, golden hair and felt soft and comfortable. It had big black eyes and a twinkle in the evening. There's also a lovely flat black nose that is always wet, so it likes to lick its nose. There was a cute little braid tied to the head, and a red bow tied to the braid.
It has been with me since I was a baby. I remember one time I made a mistake and my mother was going to hit me. Lulu saw it, and ran quickly, Shouting at her mother, trying to protect me, and her mother gave up.
My dog has a skill that other dogs don't, and whenever I play the harmonica, it will sing in rhythm, in a deep, sometimes high-pitched way. I think it's going to be a concert of its own! Do you mean my dog is tough?
So, I like dogs very much.
我最喜欢的动物是狗。因为,狗是对人最忠诚的动物。
我家也养了一只狗,它的名字叫噜噜,是一只公狗。它是一只西施狗,浑身上下长满了长长的金黄色的毛,摸上去软软的,舒服极了。它有一双黑黑的大眼睛,一到晚上就会发出闪闪的光芒。还有一只可爱的扁扁的黑鼻子,上面总是湿漉漉的,所以它总喜欢舔自己的'鼻子。噜噜的头上还扎着一个超可爱的小辫子,辫子上还扎着一只红色的蝴蝶结,分外耀眼。
从我还是婴儿的时候起,它就开始陪伴着我成长。记得有一次,我犯了一个错误,妈妈要打我。噜噜看见了,就飞快地跑过来,对着妈妈凶狠地大喊大叫,想要保护我,妈妈见它那么凶,只好放弃了。
我家的狗还有一个别的狗没有的本领,只要每次我吹响口琴时,它就会按节奏唱起歌来,时而委婉深沉,时而高亢激昂。我想,它肯定能开一个属于自己的演唱会了!你说我家的狗厉害吗?
所以,我非常喜欢狗。
I have a big dog ane I love him very much .he has two round black eyes and his sense of hearing is sensitive .
His claws are like four plum blossoms .His tail always shakes and looks very cute .In the daytime ,he likes sleepping under the sunshine .
But at night ,he is careful and keeps like the doorkeeper guards .He is smart and always eat a lot .He is meek to me but when he meets strangers ,he will bark to them .
When I become tired ,he will come and lick my face with his tongue .when I am not busy ,he will play with me .He can give me so much happiness and now I can not leave him .I love my dog because he is one of my family numbers .
I like dogs, because they are man’s good friends. They can do many helpful things to us, such as guarding our houses, greeting guests, helping the police, and so on. Some trained dogs can even lead the blind people and save people’s lives. So they‘re treated as our family members. I hope someday dogs will be in great harmony with human-beings.
我非常喜欢狗,因为它是人类的好朋友。它可以为我们做很多有用的事情,如,保护房子,问候客人,帮助警方等等。一些受过训练的狗甚至可以引导盲人、拯救人们的性命。所以它都被当做是我们的家庭成员。我希望有一天狗能与人类和谐共处。
