拋磚:少爺寫作文

(2013-04-09 09:06:26) 下一個

我家少爺畫地為牢,很怕寫作文,總說自己寫得不好。

上次被我逼了去參加學校作文比賽的選拔。考試過程是在45分鍾內,每人寫一篇作文,題目是"寫最近一次讓你流淚或者快要流淚的事情"。少爺回來說,他花了很長的時間考慮寫什麽,等他好不容易想好了,剛剛寫了個開頭,交卷時間就到了。我說,沒關係,你沒經驗,下次不要花這麽長的時間醞釀,快點開寫。再問,那你到底寫了什麽讓你傷心的事情?人家回答說,我寫我的狗死了。什麽???孩子啊,我們家從來沒有養過狗,你,你這不是胡編亂造嗎?

少爺氣憤地說,媽媽,你不覺得我的生活太平淡了嗎?我實在沒有什麽有戲劇性的故事可以寫啊。

上個周末,少爺哼哼嘰嘰不肯去中文學校。我說好吧,不過你得在家寫一篇作文。他問寫什麽,我說寫寫我們的春假吧。少爺麵露痛苦,那有什麽可寫的。問,我可不可以寫我感興趣的內容,比如telomerose?我說可以,於是他就寫了這麽一篇。

Telomerase: The Fountain Of Youth

Since the beginning of time, humans have yearned to subvert the natural course of time, with stories such as Ponce de Leons Fountain of Youth, which would grant eternal life to those who bathed in its waters. There are other stories of substances that would bring immortality, such as an Elixir of Life, and substances like jade and cinnabar. We still cant promise eternal life. But with the miracle of modern science, we now have a substance, telomerase, that can come close.

Telomerase is a ribonucleoprotein, or, more simply, an enzyme. It is a biocatalyst that affects metabolic reactions in the body. Like all enzymes, telomerase has a purpose. Its purpose is to regenerate telomeres. But what do telomeres do? Every day, cells in the body are created and destroyed. This happens through processes called meiosis and mitosis, where a cell splits into two new cells. The chromosomes are replicated into each new cell. At the end of the chromosomes are telomeres. They act as caps, preventing the chromosomes from being damaged or flawed. But when the human body runs out of telomeres and telomerase to reproduce telomeres, organs fall into disrepair and shrivel, other organs start to fail, the body becomes infertile, and eventually dies. This is known as aging.

With a surplus of telomerase, aging could theoretically slow, stop, or even reverse. In 1961, Leonard Hayflick first noticed that a cell can only reproduce between 40 and 60 times. This is known as the Hayflick Limit. Research in telomere shortening started in 1973 by a Soviet biologist, Alexey Olovnikov, who connected telomeres and aging. In 1984, Carol Greider and Elizabeth Blackburn discovered telomerase, along with Jack Szostak. However, scientists quickly realized that aging was not a direct process, but had many deciding factors. Telomerase was not as crucial as they had thought.

Since the discovery of telomerase, many experiments concerning it have been conducted. Mice born without telomerase quickly aged and gained age related disabilities. However, when supplied with telomerase, they miraculously became healthy again. Even if telomerase therapy was used on humans, many are worried that telomerase could excite tumors. In fact, telomerase is what makes cancer so deadly. Others argue that telomerase would eliminate DNA damage, stopping cancer altogether. With our limited technology, we are yet to find out whos right.

Even though telomerase is not reliable enough to test on humans, we can lengthen telomeres with simple activities such as exercise. Just taking a walk every now and then can increase a persons lifespan, and make them healthier to boot. Although miracle substances like a magic fountain may never exist, the mysteries of telomerase are sure to be unraveled soon.

怎樣教初中生寫作文我不太懂,對他寫的具體內容也不詳,貼上來求建議求引玉。

work&family 回複 悄悄話 回複綾子的評論:

哇,你好厲害啊。你的建議太好了,我馬上要把這個指示貫徹下去。今後請多多指導。
綾子 回複 悄悄話 7年紀, 寫這樣相當不錯, 我教中國孩子英文寫作,自己也上社區大學裏的英文寫作課,作為非小說類文章, 他基本上寫得很成功, 要寫得再好, 就是要加入自己的觀點,感受(哪怕是不成熟的),讓讀者能感覺到是"他"寫的, 而不是僅僅重複別人的觀點.
work&family 回複 悄悄話 回複綾子的評論:

謝謝鼓勵。七年級。
綾子 回複 悄悄話 少爺寫得不錯, 流暢,完整,上幾年級?
小野鴨子 回複 悄悄話 回複work&family的評論:
嘻嘻,不能以phd對證據的要求來要求初一生啊!
work&family 回複 悄悄話 回複小野鴨子的評論:

終於引來了一塊大玉,太好了。你的建議都非常好,我會轉告少爺。十分感謝!我覺得這篇文章還有一個問題是,他試圖賣一副永葆青春的狗皮膏藥,但並沒有提出足夠的證據。
小野鴨子 回複 悄悄話 客氣話就不說了,就寫作評兩句,不同意請勿介意:
(1)短促的句子很多,尤其是第二段。如果能用連詞或者從句把相關的短句子連起來,讀起來會更流暢,行文的邏輯性會更強。
(2)倒數第二段和第三段如果重組一下會更好。比如說,倒數第三段第一句“With a surplus of telomerase, aging could theoretically slow, stop, or even reverse.”作為中心句,與次段落剩下的句子關係不大(我知道它們在作者心中的聯係,但是。。。)

work&family 回複 悄悄話 回複西門祝的評論:

謝謝首長指示,我會戒驕戒躁戒push.
金筆 回複 悄悄話 恭喜,貴公子乃有才之人也。。。
西門祝 回複 悄悄話 少爺自己有興趣,他遲早自己會走這條路。千萬不要 over push,小孩有自尊心,你一 push,他不幹了。還不如鼓勵他的興趣方向,因勢利導,有事半功倍的效果。切切。。。
work&family 回複 悄悄話 回複金筆的評論:

謝謝好建議!我沒有想到這個可能,因為孩子一直對這方麵感興趣。趕緊試了一下,沒有找到其他完全相同的出處,倒是馬上找到了我的博克。上初一。
work&family 回複 悄悄話 回複西門祝的評論:

我也是這麽想,還寫了這篇“推媽不止”
http://blog.wenxuecity.com/myblog/34338/201303/12916.html

目前隻能說未遂。
西門祝 回複 悄悄話 少爺如不想當臨床醫師,學 Pharmacology 或 Biochemistry 今後搞研究也很好玩。隻要能找到 Grant,沒有搞臨床的壓力。混進 Sandia Lab 一類的,吃喝玩樂挺開心呢。哈哈。。。
金筆 回複 悄悄話 建議您將作文隨機的選幾句,加上雙引號,google 一下,如果不是抄的話,那這個孩子很了不起。
寫的基本不錯,是初幾?
西門祝 回複 悄悄話 少爺有上醫學院的潛質。可先從 Biology、或 Neuroscience 入門,進醫學院。日後上 Pharmacology 或學臨床。先道喜了。
登錄後才可評論.
