英语写作遗传与环境

『壹』 先天遗传与后天环境的英语作文

Today the way we consider human psychology? and mental development is heavily determined by the genetic sciences. We now understand the importance of inherited characteristics more than ever before. Yet we are still unable to decide whether an indivial's personality and development are more influenced by genetic factors (nature) or by the environment (nurture).

Research, relating to identical twins, has highlighted how significant inherited characteristics can be for an indivial's life. But whether these characteristics are able to develop within the personality of an indivial surely depends on whether the circumstances allow such a development. It seems that the experiences we have in life are so unpredictable and so powerful, that they can boost or over-ride other influences, and there seems to be plenty of research findings to confirm this.

My own view is that there is no one major influence in a person's life. Instead, the traits we inherit from our parents and the situation and experiences that we encounter in life are constantly interacting. It is the interaction of the two that shapes a person's personality and dictates how that personality develops. If this were not true, we would be able to predict the behavior and character of a person from the moment they were born. In conclusion, I do not think that either nature or nurture is the major influence on a person, but that both have powerful effect

『叁』 关于保护环境的英语作文80词左右

写作思路：可以写保护环境人人有责，接着说一些保护环境的具体措施以及好的方法等等，中心明确。

正文：

Everyone has the responsibility to protect the environment. It seems that environmental protection is far away from us, but it is always around us. The problem of environmental pollution can not be ignored.

保护环境人人有责提起环保，似乎离我们很远，但它却时刻在我们身边。环境污染这个问题确实不容忽视。

To protect the environment, I have the following suggestions: we should cherish energy and not waste water and electricity resources; we should take good care of greening, not picking flowers and plants, not trampling on grass, not cutting trees; we should not create too much waste, such as plastic bags, and use as little as possible; we should know how to use waste, and useless newspapers, magazines, bottles, etc. should be sent to the purchasing station for waste recycling.

保护环境我有以下几点小建议：要爱惜能源，不浪费水电资源；要爱护绿化，不乱摘花草，不践踏草地，不乱砍树木；不要制造太多废物，像塑料袋等应尽可能少用；要懂得废物利用，没用的报纸、杂志、瓶子等应送到收购站进行废物回收。

We should pay attention to environmental hygiene, not spitting, not littering, fruit debris should be put into the stbin. These are all the ways that we can and should do.

要注意环境卫生，不可以随地吐痰，不能随地扔垃圾，果皮杂物应放进垃圾箱。以上的这些都是我们能够做到，并且应该做到的方法。

『肆』 请帮我找一篇有关“遗传”的英语作文范文！

Genetics and the saying goes, "plant melons and you get melons, sow beans and you get beans." This simple and concise language which truly reflects the universal law of the biological species from generation to generation. It has long been discovered organisms (including plants and animals and even human) characters can be transmitted from one generation to the next generation. This is genetic, the color is the reason why people like features such as the height of the reasons always look like their parents. Ecologists found in the colorful, mysterious phenomenon will have its genetic material foundation it is found in the nucleus DNA. Also composed of chromosomal DNA and protein. Every human nucleus of a mature cell containing 46 or 23 pairs of chromosomes. have tens of thousands of human genetic information stored in it directly with the naked eye can not even see the tiny little between their chromosomes. Back in the 18th century the 1960s, as genetic material DNA in the nuclei of pus were found. From the 1940s, scientists have discovered the 19th century with a film clip, the pneumococcal pathogenic nucleic acid extraction. Another film clip will not, the non-pathogenic cocci genetic trait change, into a film clip and the pneumococcal disease, the mystery goes without saying. DNA to carry a film clip of genetic information, such as sexual transmitted disease and another pathway, so DNA is the carrier of genetic information. Genetic material is the foundation. Higher biological complex genetic traits, and enormous amounts of information. There are 46 chromosomes in the DNA molecule so how can accommodate large amounts of information. This was perplexed mankind's age-old mystery. Scientists discovered in 1953 called deoxyribonucleic acid (DNA, a DNA molecule) structure, The answer is only the truth of this mystery, a landmark discovery that won a Nobel Prize. more important is to bring about a revolutionary change in the field of life sciences. DNA is a biological macromolecules, the basic structure of tens of millions of units -- deoxynucleotidyl link from chainlike structure, Further further by the two chains together and come into the two-track train track Wanru shape sleeper section of the track is equivalent to one end connected to the one deoxynucleotidyl DNA molecule. Only four types of human DNA deoxynucleotidyl different chemical composition. repeat elements arranged in irregular and seems to turn up. Now that the 46 chromosomes containing about one billion deoxynucleotidyl CPC, which is equivalent to one billion pieces of a long sleeper tracks. Can be seen every one of the four types of chromosomes have deoxynucleotidyl great quantity, So four deoxynucleotidyl row from the end of the DNA molecule to the other end, there are a variety of sequencing. This particular deoxynucleotidyl sequencing hold infinite number of genetic information. Stored so many genetic traits to the long chain of human chromosomal DNA. When the average extension of up to four centimeters in length. even imagine it can be stuffed into a microscope to see the very small cells. Long-chain DNA molecules form a spiral structure in space first, and then after several circled and the bar-shape folded chromosome, the length incredible times to be reced by nearly 10,000, able to accommodate only six to seven microns in diameter of the nucleus. Generally speaking, heredity is determined by genes, cell division, nuclear or accuracy of the chromosome replication to a new set of chromosomes, deoxy nucleotide sequencing, and its cell structure and the same, Therefore, the parents of a comprehensive and correct transmission of genetic information to offspring. 23 pairs of chromosomes in the cells of human eggs, sperm cell from the father of 23, inherited his father's genetic information. Another 23 mothers from the mother's egg faithfully preserved genetic information, and consequently, Growth almost become characters in the offspring of parents is the "." This is the "fruit How can you get beans grow beans How can get melons" scientific truth lies. DNA is the genetic material foundation, the gene is located on chromosome DNA fragment organisms of different genes may determine different traits, can be described as a specific gene carrying the genetic information of a particular character, In fact it is the basic unit of heredity genes. Scientists speculate the body cells of chromosome 46 with a total of about 100,000 genes. This shows how great the human genetic information. Along with the rapid development of science and technology. Scientists in 1985 seeks to clarify the 46 human chromosomes 1 billion Deoxymononucleotides sequencing. This is awesome global Human Genome Project was launched in 1990, has achieved a great success People plan to make the full sequencing of the human genome completed in 2005. to decipher all human genetic information to enable mankind to the first fully self-understanding at the molecular level. Human genes determine the genetic traits of indivial characters through a variety of protein and is emerging. It is not difficult to imagine that genes control protein synthesis is necessary genetic information. This embedded in the gene can convey to the residence of protein to maintain a specific genetic trait. So if DNA is the carrier of genetic information, genetic protein is the discoverer. The molecular weight by linking thousands of amino acids -- basic unit. The human body is composed of 20 kinds of amino acid. amino acid protein in the form of thousands of different kinds of protein sequencing. with the implementation of their own specific functions, and represents a specific biological traits. Scientists through a long and arous exploration, found that the DNA information through other nucleic acids -- messenger ribonucleic acid (mRNA) and protein relay. MRNA molecules from the four nucleotides (Note : deoxynucleotidyl DNA and the four completely different species) in different sequencing component. A chain molecule DNA sequencing can deoxynucleotidyl the strict guidance of the specific mRNA molecules proced nucleotide sequencing. This DNA molecules on the accurate transmission of genetic information to mRNA molecules, a process known as transcription. A specific gene, the DNA fragment, Genetic information can be transmitted through the transcription of the mRNA molecule which nucleotide sequencing. MRNA molecule three adjacent nucleotide sequencing was called codons. is one of the amino acids each codon codes, a 20 amino acids each codon. So the mRNA molecule sequencing genetic information that the codon can be strictly guided protein of 20 amino acid molecule sequencing. MRNA so that the genetic code is carried on in descending order of amino acids, linked to protein This process is known as translation. They can make the intrinsic link between a popular metaphor : mRNA molecule sequencing of the genetic code or code telegram ordering mRNA molecules are arranged in the codon translated into protein molecules of amino acid sequencing. and the cable can be translated into a series of codes is the precise meaning of the wording. What is truly amazing is that some of them have strange psychedelic various low. It does not use a set of higher organisms have complex genetic code, the implementation of similar genetic code Messenger RNA is the genetic information flows from DNA, and then the flow of protein. However, the genetic changes may also bring misfortune to Ecologists even human suffering. All things the development of a two-edged sword. Mankind in the long process of adaptation to changes in the external environment and survive, Nuclear gene unknowingly carried out extremely slow evolution, evolution and improvement, Genetic stability and gene evolution is the driving force behind evolution of biological species. If some genes in the human genetic change caused by congenital diseases, often with lifelong eroded. Hemophilia is a typical example. Because of a lack of a clotting factor disease, the patient's organs and tissues once sustained minor injuries, it will stop the bleeding. Due to the lack of clotting factor that makes the blood coagulate into pieces and the wounds difficult to stanch bleeding. Some genetic diseases. only one gene or replace the lost one deoxynucleotidyl on the whole lifelong disease caused by the loss of gene function. Apart from congenital genetic diseases, gene mutations acquired the disease may be triggered. Chemical carcinogen in the human body, will be integrated into the human DNA molecule, This interferes with the normal transmission of genetic information, resulting in malignant transformation of cells, the human body, trigger cancer. With the rise of molecular biology, and the rapid development of cutting-edge technology. Scientists have can be applied to "elements" have high-power microscope to see that even in the gene splicing, repair and replacement. Therefore, to conquer the many genetic diseases or diseases caused by gene mutations are not far off. Even according to the wishes of scientists to one foreign gene into a plant organisms can create a new species. This is the magic of genetic engineering. This is to prevent crop pests, improving livestock species, biological pharmacy, and so has tremendous value. Therefore, the master of the human genome and the genetic mysteries, they use it brought the benefit of mankind. its development prospects are very bright.

There is no denying that,currently,a controversial debate has risen as to whether American TV dramas are beneficial to our study or merely entertaining .As I see it,the American TV dramas to study is what roofs to rooms,packs to bags ,attaching exceedingly importance to our English studies .Hardly can I imagine the world without the fascination of it which gets indivials all over the world work themselves into buries over it .Nevertheless ,as the old saying goes “No garden has two weeds”,therefore ,on no account can we turn a blind eye to the unforeseeable consequences it caused .There is no consensus among people concerning this controversial issue
Some people hold the perspective that watching American TV dramas can enhance their language sense while someone maintain that watching American TV dramas has nothing to do with learning.When it comes to our studies,I frown on the latter,because watching American TV dramas not only help us learn multitudes of words but broaden our horizons,strengthen our humanistic attainments and enrich our lives,making us more competitive in the society.So hence one can see that studies have a significant relation with watching American TV dramas.However,needless to say,nothing will be more cogent than to be stated as follows.In accordance with a recent survey concted by UNESCO .among people of all ages around the world ,about 79.4﹪ of the teenagers tend to watch comedies of American TV dramas ,That is to say,The majority of person watch American TV dramas only for purpose of relaxing themselves .But is there no advantages involved in we shouldn’ take apart for the all

『陆』 英语作文-污染环境

Human activities caused by the decline in environmental quality and harmful to human beings and other living a normal existence and development of the phenomenon. When the concentration of waste into the environment or harmful to human beings and other living normal existence and development of the material more than the total environment of self-purification capacity, it will cause environmental pollution. Environmental pollution is the main reason for the irrational use of resources and waste, so that the resources available as a waste discharged into the environment and cause harm. Environmental pollution can not only cause acute poisoning and chronic hazards, but the organism can have an impact on the immune function, the genetic material from organisms change. Long-term exposure to carcinogenic factors in the environment can cause cancer, called the environment (of) cancer. Environmental pollution by environmental factors can be divided into air pollution, water pollution and soil pollution, and so the pollutants can be divided into the nature of biological contamination, chemical pollution and physical pollution, according to the shape of pollutants can be divided into air pollution, waste water pollution, Solid waste pollution, noise pollution, radiation pollution; according to the cause pollution can be divided into the proction of pollution and pollution of life, the former can be divided into instrial pollution, agricultural pollution, traffic pollution, and so on the distribution of pollutants can be divided into Global pollution, regional pollution and local pollution.

中文翻译;人类活动所引起的环境质量下降而有害于人类及其他生物的正常生存和发展的现象。当进入环境的废物浓度或有害于人类及其他生物正常生存和发展的物质总量超过环境自净的能力，就会造成环境污染。环境污染产生的主要原因是资源的不合理使用和浪费，使可用资源作为废物排入环境而造成危害。环境污染不仅能引起急性中毒和慢性危害，而且能对机体的免疫功能产生影响，引起生物体遗传物质的变化。长期接触环境中的致癌因素还可引起恶性肿瘤，称为环境(性)癌。环境污染按环境要素可分为大气污染、水体污染和土壤污染等；按污染物的性质可分为生物污染、化学污染和物理污染；按污染物的形态可分为废气污染、废液污染、固体废物污染、噪声污染、辐射污染等；按污染产生的原因可分为生产污染和生活污染，前者又可分为工业污染、农业污染、交通污染等；按污染物的分布范围又可分为全球性污染、区域性污染和局部性污染等。
