什么是生物英语作文【一】

Long, long ago, there were two brothers, the one rich and the other poor. When Christmas Eve came, the poor one had not a bite in the house, either of meat or bread; so he went to his brother, and begged him, in God's name, to give him something for Christmas Day. It was by no means the first time that the brother had been forced to give something to him, and he was not better pleased at being asked now than he generally was.

"If you will do what I ask you, you shall have a whole ham," said he. The poor one immediately thanked him, and promised this.

"Well, here is the ham, and now you must go straight to Dead Man's Hall," said the rich brother, throwing the ham to him.

"Well, I will do what I have promised," said the other, and he took the ham and set off. He went on and on for the livelong day, and at nightfall he came to a place where there was a bright light.

"I have no doubt this is the place," thought the man with the ham.

An old man with a long white beard was standing in the outhouse, chopping Yule logs.

"Good-evening," said the man with the ham.

"Good-evening to you. Where are you going at this late hour?" said the man.

"I am going to Dead Man's Hall, if only I am on the right track," answered the poor man.

"Oh! yes, you are right enough, for it is here," said the old man. "When you get inside they will all want to buy your ham, for they don't get much meat to eat there; but you must not sell it unless you can get the hand-mill which stands behind the door for it. When you come out again I will teach you how to stop the hand-mill, which is useful for almost everything."

So the man with the ham thanked the other for his good advice, and rapped at the door.

假如我是生物学家……

假如我是生物学家,我要采毒蛇的毒液和企鹅的毛。

一个娇阳似火的早晨,我们不知不觉地走到了热带丛林,这时,走在前面的助手大声喊到:“什么玩意?!”只见一只双头蛇从从石缝里钻了出来,转过头用那冷酷的眼神盯着我们。“这蛇怎么长着两个脑袋?!”我不慌不忙地说:“这东西捉回去肯定有用。”我连忙用钳子夹住它的尾巴,用手握紧它的头,麻利地把它装进麻袋。

我拿出地图一看,下一个目标居然在北极,不知道什么时候才能到达目的地呀!就在这时候,一驾直升机从天而降,我赶忙“飞”上直升机……冰天雪地的北极到了,我跳下直升机,寻找目标,我的助手说:“看!那只企鹅正合适。”说干就干,我悄悄地逼近那只正在孵蛋的企鹅,轻轻地拔了根毛放进腰包里……

回到实验室,我把双头蛇抓了出来,用左手按着那两个脑袋,右手把小瓶子贴紧它的嘴巴,把毒液挤了出来,经过无数次试验,才把它制成了药,能治白血病拯救上万人的生命。然后,我把那孤零零的毛放进了新开发的复制器,我们不分昼夜地工作,它们才全部被制成了毛衣,登山运动员如虎添翼。有了我特制的毛衣,北方人冬天就不用开暖气了,还能为祖国节约不少能量资源哩!

假如我是生物学家,我还要……

当新学期来临时,许多学生对新生活表现得很兴奋。在大学,新生快乐地享受着自由。在接下来的四年里,他们希望过着高中描绘的'美好生活。但事实是,大学生活中有很多东西要学。

First, the major knowledge occupies the most important role. As a student, learning knowledge is their job, while many students focus on playing cellphone in the class, or just sleep. They lose interest in studying when they come to the free environment. Mastering the professional skill helps them to be competitive. The sad thing is that most of them can't realize it.

首先,专业知识占据着最重要的角色。作为一名学生,学习知识是他们的工作,而很多学生在课堂上玩手机,或者睡觉。当他们来到自由的环境后对学习失去了兴趣。掌握专业技能帮助他们提高竞争力,可悲的是,大多数人没有意识到这一点。

Second, as there is much free time, they can make use of it and gain the valuable experience. Students can join some clubs to develop more interest, or find part-time jobs. It is better than to stay in the dorm and play computer games all the time.

第二,由于空闲时间多,他们可以充分利用好这些时间,并从中获得宝贵的经验。学生可以参加一些活动来发展更多的兴趣爱好,或找份兼职工作。比呆在宿舍玩电脑游戏好多了。

A lot of students feel lost in the campus, because they don't plan campus life well. The things you learn will make you different in the future.

很多学生因为没有计划好校园生活在所以迷失了。所学到的东西会让你在未来有所作为。

20xx年的一天,一名生物学家正和他的研究小组成员一道在实验室里研究着“提取壁虎断尾再生基因”的课题。他们在显微镜下仔细地观察着,在离心机旁耐心地等待着,全神贯注的神情呈现在他们的脸庞上。你们知道那人是谁吗?那就是20年后的我。

我们生活在这个世界上,每个人都应该为社会做贡献。但人各有志,因此所选择的职业也各不相同。有的人想当大官,有的'人想做富商,有的人立志当教师,而当一名生物学家,攻克生物基因移植难题却是我从小学就开始的梦寐以求的愿望。

在我的带领下,我们这个课题组首先观察了壁虎断尾再生的过程。被断尾后的壁虎,在没有任何治疗的情况下,经过几天的休养,竟然断尾再生。我们看着它重新长出来的尾巴,受到了很大的启发。既然壁虎的断尾能够重新生长,那么它的体内一定存在着某种再生基因。如果能将这种基因提取出来,移植到肢体伤残的人身上,使伤残的肢体再生,那将是一件造福人类的大好事呀!我们全组人员立即制定了一整套的研究方案。经过一年多的努力,经过无数次的失败,再生基因终于被我们从壁虎体内成功地提取出来了。我们把它注射到残肢的小白鼠身上,结果几星期后,这只小白鼠的腿成功地长了出来。通过众多专家的再次可行性论证,我们将此基因用于临床病例。这是一位因意外事故被截去一根手指的病人,我们将再生基因注入他的体内,经过几个月的漫长等待,他失去的手指又重新长了起来。

我们的研究终于取得了丰硕的成果,为此,我们全组人员都流下了激动的泪水。这项技术使生物遗传基因的研究有了突破性的发展,也填补了我国医学史上的一项空白。
