3．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 2012Nobel Prize in Medicine with Japanese stem cell （干细胞） researcher Shinya Yamanaka．
Like so many scientists，Gurdon shows us where the power of curiosity and perseverance （坚持）can lead．
At the age of 15in 1948，Gurdon ranked last out of the 250boys 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 laboratory earlier and left later than anyone else．He experienced thousands of failures．
"I believe that we will，in the end，understand everything about how cells actually work．，"Gurdon said．
In 1962，Gurdon took a sell from an adult frog and moved its genetic （基因的）information into an egg cell．The egg cell then grown into a clone of the adult frog．This technique later helped to create Dolly the sheep in 1996，the first cloned mammal in the world．
In 2006，Gurdon's work was developed by Yamanaka to show that a sample （样本） 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 prefers 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 catch the chance．"

分析 这篇文章主要介绍一位诺贝尔医学奖获得者John Gurdon，他在小时候受尽质疑，但是凭借着不放弃、勇往直前的精神最终获得成功．告诉我们相信越努力越幸运，我们的坚持总有回报．
解答 答案：24．B 细节排序题．根据整篇文章内容第六段句子in 1962，Gurdon took a cell from an adult frog，The egg cell then grown into a clone of the adult frog．可知他先从成年青蛙中取一个细胞；之后将这个青蛙的基因信息导入到另一个卵细胞中；然后这个卵细胞成长为了一只克隆青蛙；第六段第二行句子This technique later helped to create Dolly the sheep in 1996，利用这一技术1996年有了克隆羊多莉；倒数第二段句子In 2006，Gurdon's work was developed by Yamanaka to show that a sample （样本） of a person's skin can be used to create stem cells2006年利用人体皮肤创造干细胞．所以正确顺序是b-d-e-a-c，故选B．
25．D 词义猜测题．根据第三段第一行句子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"他在生物等理科课程方面的成绩在高中是250个男生中的最后一名，可知老师说他做科学家的梦想应是"滑稽的，荒谬的"．故选D．
26．D 细节理解题．根据第四段第一行句子In spite of his teacher's criticisms，Gurdon followed his curiosity and kept working hard．他不管老师的看法，依旧跟随自己的好奇心坚持努力工作．可知John不管老师的看法，依旧努力工作．故选D．
27．B 主旨归纳题．根据最后一段第一句Luck favors the prepared mind，机会留给有准备的人．可知"机会总是留给有准备的人"，尽管很多工作没有结果，但只有那样，当机会来临时我们才能抓住它．同时全篇也都描写了主人公为实现梦想所做的各种努力，有准备才会成功，故选B．
