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 in science and finished bottom of his class. However,aged 79,the very same Gurdon shared the 2012 Nobel Prize in Medicine with Japanese stem cell (干細胞) researcher Shiny a 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 criticism,Gurdon followed his curiosity and kept working hard. He went to the lab earlier 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," said Gurdon.'
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 (克隆) of the adult frog. This technique later helped to create the sheep Dolly 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 of a person's skin can be used to create stem cells. Using this 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."

1. C細節(jié)理解題。由題目中的關鍵詞2012 Nobel Prizein Medicme ,可回原文定位于第二段。根據(jù)"...Gurdon shared the 2012 Nobel Prize in Medicine with Japanese stem cell researcher Shinya Yamanaka."可知,Sir John Gurdon和Shinya Yamanaka共同獲得諾貝爾醫(yī)學獎。
2. B細節(jié)理解題。由題目中的關鍵詞In what order,可回原文定位于第七、八段。正確的順序是:take a cell from an adult frog→move the frog's genetic information into an egg cell?→grow into a clone of the adult frog→create the sheep Dolly → use a person's skin to create stem cells。
3. D詞義猜測題。由題目中的關鍵詞ridiculous,可回原文定位于第四段。根據(jù)"Gurdon ranked last out of the 250 boys"可以判斷,這與成為一個科學家的夢想差距太大。ridiculous意為"荒謬的,可笑的"。
4. D細節(jié)理解題。根據(jù)第五段第一句"In spite of his teacher's criticism,Gurdon followed his curiosity and kept working hard."可知,不在意老師的批評, Gurdon仍然繼續(xù)努力。根據(jù)第二段第二句"As a boy,he was told he was hopeless in science and finished bottom of his class."可知,他被告訴他在科學方面沒有希望,排除A;根據(jù)第四段第一句"At the age of 15 in 1948.Gurdon ranked last out of the 250 boys..."可知,他是最后一名,排除B;根據(jù)倒數(shù)第二段最后一句"Using this technique,doctors can repair a patient's heart after a heart attack."可知,修復心臟是可能的,排除C.
5. B主旨大意題。文章通過Gurdon的故事說明了幸運總是光臨有準備的頭腦。

I'm Alfred. I was born with a problem in my backbone and mobility (行走能力) was a big challenge (挑戰(zhàn)) for me,but thanks to my teachers and friends,my school life was excellent.
My friends and I used to sit together and have lots of fun. Whenever we got a free period,we used to start shouting or play games. I took part in all competitions,such as poetry writing,story writing,painting and all activities on Teachers' Day or somebody's birthday and had much fun.
My English teacher was very tall. The moment she entered the class,we would all sit quietly and open the books. She would encourage me by giving me important assignments and also morning news to read during the assembly. She would come down and listen to my English debate (辯論) ,which made me participate (參加) in all debate competitions.
The same was true of my biology and science teacher. She was very nice and sweet. She would always give me extra information on the biology project. I could not go to the lab for practicals ( lessons or exams in science,cooking,etc. in which you have to do or make something yourself rather than write or read about it) ,so she would bring down the lab and help me with the biology and science practicals and would give me excellent marks.

I was never shouted at or made fun of or scolded (批評) by any of my friends or teachers.
Today I often see the terrible punishments given to students on TVs. I feel very sad.
