15.Life is full of surprises and you never know how things will turn out.
Sir John Gurdon is a good example of this.As a boy,he was told he was hopeless at science and finished bottom of his class.Now,aged 79,the very same Gurdon shared the 2012 Nobel Prize in Medicine with Japanese stem cell(干細(xì)胞) researcher Shinya Yamanaka.
Like so many scientists,Gurdon shows us where the power of curiosity and perseverance(堅持不懈) can lead.
At the age of 15 in 1948,Gurdon ranked last out of the 250 boys at his high school in biology and every other science subject.Gurdon's high school science teacher even said that his dream of becoming a scientist was"quite ridiculous".
In spite of his teacher's criticisms,Gurdon followed his curiosity and kept working hard.He went to the lab early and left later than anyone else.He experienced thousands of failures.
"My own belief is that we will,in the end,understand everything about how cells actually work."Gurdon said.
In 1962,Gurdon took a cell from an adult frog and moved its genetic(基因的) information into an egg cell.The egg cell then grew into a clone(克。 of the adult frog.This technique later helped to create Dolly the sheep in 1996,the first cloned mammal(哺乳動物) in the world.
In 2006,Gurdon's work was developed by Yamanaka to show that a sample (樣本) of a person's skin can be used to create stem cells.Using the technique,doctors can repair a patient's heart after a heart attack.
"Luck favors the prepared mind,"Gurdon told the Nobel Prize Organization."Ninety percent of the time things don't work,but when they do,you have to seize(抓住) the chance."

分析 文章大意:這篇文章主要講述了Gurdon,一位諾貝爾獲得者的故事.生活往往充滿了驚喜,你永遠(yuǎn)不知道下一秒會發(fā)生什么.Gurdon就是一個鮮活的例子.當(dāng)他還是小孩的時候,他是班級的倒數(shù),可誰曾想過就是這樣一個被認(rèn)為與科學(xué)家無緣的男孩長大后,在79歲之際獲得了在干細(xì)胞研究方面的諾貝爾獎.像其他許多科學(xué)家一樣,是好奇與堅持的力量鑄就了他今日的輝煌.即使被老師和同學(xué)們不看好,他仍然堅持早到晚出實驗室,一遍遍嘗試.1962年,他將一只成年青蛙的基因信息導(dǎo)入到卵細(xì)胞中成功的克隆了這只成年青蛙,這一技術(shù)對后來世界上第一只哺乳動物山羊多莉的克隆起著關(guān)鍵的作用.2006年,Gurdon采集人的皮膚樣本創(chuàng)造干細(xì)胞,使用這一技術(shù)醫(yī)生可以在病人心臟病發(fā)作時及快的修復(fù).通過Gurdon我們相信越努力越幸運,我們的堅持總有回報.

解答 66.答案C.細(xì)節(jié)理解題.根據(jù)"Now,aged 79,the very same Gurdon shared the 2012 Nobel Prize in Medicine with Japanese stem cell(干細(xì)胞) researcher Shinya Yamanaka."可知兩人共同獲得了諾貝爾醫(yī)學(xué)獎,故選C.
67.答案B.細(xì)節(jié)理解題.根據(jù)"in 1962,Gurdon took a cell from an adult frog"可知他先從成年青蛙中取一個細(xì)胞;之后將這個青蛙的基因信息導(dǎo)入到另一個卵細(xì)胞中;然后這個卵細(xì)胞成長為了一只克隆青蛙;利用這一技術(shù)1996年有了克隆羊多莉;2006年利用人體皮膚創(chuàng)造干細(xì)胞;依據(jù)順序綜上所述,故選B.
68.答案D.詞意推斷題.根據(jù)"At the age of 15 in 1948,Gurdon ranked last out of the 250 boys at his high school in biology and every other science subject"可知他在生物等理科課程方面的成績在高中是250個男生中的最后一名,因此老師說他做科學(xué)家的夢想是"滑稽的,荒謬的",故選D.
69.答案D.細(xì)節(jié)理解題.根據(jù)"In spite of his teacher's criticisms,Gurdon followed his curiosity and kept working hard"可知他不管老師的看法,依舊跟隨自己的好奇心堅持努力工作,故選D.
70.答案B.主旨大意題.根據(jù)"Luck favors the prepared mind",文章結(jié)尾點名主旨,可知"機(jī)會總是留給有準(zhǔn)備的人",盡管很多工作沒有結(jié)果,但只有那樣,當(dāng)機(jī)會來臨時我們才能抓住它.同時全篇也都描寫了主人公為實現(xiàn)夢想所做的各種努力,有準(zhǔn)備才會成功,故選B.

點評 快速閱讀全文,掌握文章大意,并認(rèn)真閱讀題目,把握好相關(guān)文章細(xì)節(jié),做出正確解答.

"In 1997I was found to have developed diabetes (糖尿病),believing the profession trained for the whole of my life ended,I felt very sorry.Then one of my friends said there was no reason why I should stop training and competing.That was it-the encouragement I needed.I could still be a winner if I believed in myself.I am not saying that it isn't difficult sometimes.But I wanted to prove to myself that I wasn't finished yet.Nothing is to stand in my way."
