下面为大家整理一篇优秀的essay代写范文 -- Sperm and Eggs:  Neither Active nor Passive but Interactive,文章讲述在论文《卵与精子:科学如何根据定型的男女角色构筑爱情》中,作者以卵与精子为例,坚定而严格地识别并探索了生物学科学语言中隐藏的性别定型观念。本文中的大多数证据表明,在生物学和科学文献中,通常将精子描述为主动强壮的,而卵则被认为是被动和弱小的。但是,有一个证据使我不偏不倚和科学的本质给我留下了深刻的印象:“与传统观点相反,‘卵不仅仅是一个巨大的,卵黄质的球体,精子可钻入该球体赋予新生命。相反,最近的研究表明,几乎是异端的观点认为精子和卵子是相互活跃的伙伴。” (马丁750)这条证据加上论文中的论点,为我的个人主张提供了启示:鸡蛋在生物领域应有应有的地位。                                                                

                               

Sperm and Eggs:  Neither Active nor Passive but Interactive

In the essay The Egg and the Sperm: How Science Has Constructed a Romance Based on Stereotypical Male-Female Roles, the author firmly and rigorously identifies and explores the gender stereotypes hidden within the scientific language of biology by taking egg and sperm as an example. Most of the evidence in this essay show that in biological and scientific texts, the sperm has generally been described as active and strong while the egg have been casted a role of being passive and weak. However, one piece of evidence strikes me with its unbiased and scientific nature: “Contrary to conventional wisdom, the ‘egg is not merely a large, yolk-filled sphere into which the sperm burrows to endow new life. Rather, recent research suggests the almost heretical view that sperm and egg are mutually active partners.” (Martin 750) This piece of evidence, combined with the arguments in the essay, has shed light on my personal claim: egg deserves a righteous place in biological field.

For a long period of time, sperm has been depicted as strong, active, and even aggressive, while egg is stereotyped as weak and passive. Yet scientific evidences, meaning facts and not descriptions, show that sperm has its own limitations and when compared with the egg, it is as “aggressive” as they were described. Many believe that with a “strong and forceful” tail and a large head, the sperm can swim and can penetrate and enter the egg forcefully. However, the fact is that during this process, “the forward thrust of sperm is extremely weak” (Martin 749), the sperm is trapped by the adhesive surface of the egg and “the mechanical force of its tail is so weak that a sperm cannot break even one chemical bond” (Martin 750). All these prove that the strong and active image of the sperm is exaggerated to some extent. Actually, sperm and egg work closely to get through the whole process. “in another example, ‘the driving force for engulfment of a fused sperm comes from a region of cytoplasm just beneath an egg’s plasma membrance.”

Besides, in spite of being traditionally regarded as “damsel in distress” or “sleeping beauty” that waits for the sperm’s penetration, the egg actually plays a more active role in the fertilization process. The egg attracts and traps the sperm and “adheres to it so tightly that the sperm's head is forced to be pressed against the surface of the egg” (Martin 749). This reflects that the egg is not at all passive in the whole process.

Given the images of active sperm and passive egg being overthrown, a rational and unbiased description should be given to this destined pair. On the basis of the above analysis, their relationship should be best described as “interactive”. Hopefully, this will break the cultural expectations and stereotyped view on the sperm and egg. But this is very necessary: only by describing things as what it is, can we avoid unnecessary prejudice and move forward toward the ultimate truth of the world.

In a word, based on the evidences provided in the essay, in the fertilization process, the sperm and egg are both playing a proactive role. Egg in no sense should be degraded but rather dealt with a fair treat.
