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 Nobe 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(克隆) of the adult frog. This technique later helped to create Dolly the sheep in 1996, the first cloned mammal(哺乳动物）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.” 36.Who won the 2012 Nobel Prize in Medicine? A. Sir John Gurdon B. Shinya Yamanaka. C. Sir John Gurdon and Shinya Yamanaka D. Gurdon’s science teacher. 37.In what order are the followings mentioned in the passage?     a. create the sheep Dolly b. take a cell from an adult frog c. use a person’s skin to create stem cells d. move a frog’s genetic information into an egg cell e. grow into a clone of a frog A. b—a—c—d—e B. b—d—e—a—c C. b—d—a—c—e D. b—e—d—a—c 38.What does the underlined word “ridiculous” mean? A. 无知的 B. 无畏的 C. 荒废的 D. 荒谬的 39.According to the passage, which statement is TRUE? A. As a boy, he was told he was hopeful. B. He ranked first at his high school in biology. C. It’s impossible for the doctors to repair a patient’s heart after a heart attack. D. In spite of his teacherˈs criticisms, he kept working hard. 40.What’s the main idea of the passage? A. Ninety percent of the time things don’t work. B. Luck favors the prepared mind C. Life is full of pleasure. D. How to know cells actually work. 【答案】C、B、D、D、B 【解析】文章大意：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，但是凭着不放弃、勇往直前的精神最终获得成功。  36. 根据文中Now, aged 79, the very same Gurdon shared the 2012 Nobe Prize in Medicine with Japanese stem cell(干细胞) researcher Shinya Yamanaka.可知答案，故选C。 37. 根据文中In 1962, Gurdon took a cell from an adult frog and moved its genetic(基因的）information into an egg cell.

C On February 9th, 2013, Sarah Darling was walking along the street when she met a homeless man named Billy Ray Harris. She reached into her change purse, emptied out all the coins she had and gave them to the homeless man. Neither of them realized that this small generous act would change their lives. Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the following morning. She and her husband, Bill Krejci, rushed to see if they could find Billy. The homeless man was not only in the same place, he also immediately returned the ring. The grateful couple paid him back for his honesty by emptying out their pockets of all the money they had. Bill Krejci, a web designer, felt that he needed to do something more for this amazingly honest man. So on February 18th, he set up a special page to raise money for him. In just four days, Billy received over $85,000 and there seems to be no end yet. That is not enough. Billy is living with a person who is generous instead of living in the streets. And that's not all—thanks to the news report, he got together again with his older brother, Edwin Harris, who he had been unable to find for 27 years. All the good luck is just because Billy did the right thing—returning something that did not belong to him. 46.When did Sarah realize that she had also given Billy the diamond ring? A. On February 9th, 2013. B. On February 10th, 2013. C. On February 18th, 2013. D. On February 22nd, 2013. 47.Which of the following is NOT mentioned in the passage? A. Billy is living with a generous person. B. Billy has found his brother. C. Billy bought a diamond ring. D. Billy appeared in the news report. 48.The underlined word "That" in Paragraph 4 refers to (指代) ________. A. returning the ring B. setting up a page C. living in the streets D. receiving money 49.Who did the diamond ring belong to? A. Sarah Darling. B. Billy Ray Harris. C. Bill Krejci. D. Edwin Harris. 50.What's the best title of the passage? A. Generous Woman Changed Her Own Life B. Kind Man Set Up Special Page C. Homeless Man Returned Diamond Ring D. Many People Donated Much Money 【答案】B、C、D、A、C 【解析】【文章大意】短文主要记述了一个人在施舍给一个乞讨者时，不小心把钻石戒指给了这个人。后来这个乞讨者归还了戒指，并因此受到一笔很大的捐款，还找到了自己失散多年的兄弟。可以说这一切都是诚实带来的好运。 46. 根据第一段句子On February 9th, 2013, Sarah Darling was walking along the street when she met a homeless man named Billy Ray Harris.2013年2月9日，萨拉达林在街上走着，遇到了一个叫比利雷哈里斯的流浪汉。第二段句子Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the following morning.莎拉没有意识到她不仅给了比利她所有的零钱而且她还把她的钻戒放在她的零钱钱包里，直到第二天早上才意识到，可知应该是2013年2月10日。故选B。 47. 根据倒数第二段句子Billy is living with a person who is generous比利和一个慷慨大方的人生活在一起，可知A选项在文章中提到了；根据倒数第二段句子Thanks to the news report, he got together again with his older brother多亏了这篇新闻报道，他又和他的哥哥再次相聚。可知B选项提到了；根据倒数第二段句子Thanks to the news report多亏了新闻报道，可知，D选项也提到了。根据第二段句子Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the following morning.莎拉没有意识到她不仅给了比利她所有的零钱而且她还把她的钻戒放在她的零钱钱包里，直到第二天早上才意识到。可知C选项这句话不符合文意，这个钻石戒指是Sarah的，并不是Billy买的。故选C。 48. 根据第三段句子So on February 18th, he set up a special page to raise money for him. In just four days, Billy received over $85，000and there seems to be no end yet.因此，在2月18日，他设立了一个特别的页面为他筹集资金。仅仅4天，比利就得到了8.5万美元的收入，而且似乎还没有结束。可知，这里的that 代指的应该是前文中所提到的事情，这里应该指的是当Billy归还了戒指之后，在Bill的努力下，人们为他捐了很多钱。故选D。 49. 根据第二段句子Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the following morning.莎拉没有意识到她不仅给了比利她所有的零钱而且她还把她的钻戒放在她的零钱钱包里，直到第二天早上才意识到。The homeless man was not only in the same place, he also immediately returned the ring.那个无家可归的人不仅在同一个地方，他还立即把戒指还给了他。可知钻石戒子属于莎拉•达林。故选A。 50. 根据整篇文章内容及其第二段句子Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the following morning.莎拉没有意识到她不仅给了比利她所有的零钱而且她还把她的钻戒放在她的零钱钱包里，直到第二天早上才意识到。The homeless man was not only in the same place, he also immediately returned the ring.那个无家可归的人不仅在同一个地方，他还立即把戒指还给了他。可知这篇短文讲述的是一个诚实的流浪汉归还了Sarah无意间给他的一枚戒指，而他的这份善良也给他自己带来了回报。他不仅从人们那里得到了很多捐款，而且找到了他失散多年的哥哥。故这篇短文的标题应该是无家可归的人返回钻石戒指。故选C。 D Beauty sleep is a real thing, researches have shown that people who have enough sleep look more attractive (有魅力的) to others. A few bad nights are enough to make a person look "espe-cially" more ugly, their sleep experiments show. The researchers asked 25 university students to join in their sleep experiment. They were asked to get a good night's sleep for two nights. A week later, they were asked to sleep for only four hours every night for two nights in a row. The researchers took make-up free (素颜) photos of the vol-unteers after both the good and the bad sleep. Next, they asked 122 strangers to have a look at the photos and judge (评价) them on attractiveness, health and sleepiness, as well as asking them, "How much would you like to make friends with this person in the picture?" The strangers were good at judging if the person they were looking at was tired, and, if they were sleepy, their attractiveness score was low. The strangers also said they wouldnˈt want to socialize with the tired students. The researchers say this is natural for people. An unhealthy-looking face makes people run away. In other words, people don't want to hang around with people who might be ill. Dr. Brewer, an expert at the University of Liverpool said, "Judgement of attractiveness is often unconscious (无意识的), but we all do it, and we are able to judge on even something small like whether someone looks tired or unhealthy. This study is a good reminder of how important sleep is to us." 51.When did the researchers take make-up free photos? A. After two nightsˈ good sleep. B. After two nightsˈ bad sleep. C. Before the experiment. D. After both two nights' good sleep and two nights' bad sleep. 52.The researchers asked the strangers to do the following EXCEPT ______. A. telling who looked healthier B. telling who didn't have many friends C. telling who missed a lot of sleep D. telling who was attractive 53.What kind of friends did the strangers like to make? A. The people who were tired. B. The people who were sleepy. C. The people who were unhealthy. D. The people who were attractive and energetic. 54.What does the underlined word "socialize" mean in Chinese? A. 合伙 B. 玩耍 C. 交往 D. 共事 55.According to the passage, which of the following is the best title? A. Beauty Sleep, More Attractive B. More Sleep, More Friends C. Less Sleep, Fewer Friends D. No Attractiveness, No Friends 【答案】D、B、D、C、A 【解析】【文章大意】本文主要介绍了睡眠对我们的重要性，美容觉能让人看起来更有魅力。 51. 根据短文内容The researchers took make-up free (素颜) photos of the volunteers after both the good and the bad sleep .可知，研究人员在志愿者有两个晚上好的睡眠和两个晚上不好的睡眠之后都进行了拍照。故选D。 52. 根据短文内容Next, they asked 122 strangers to have a look at the photos and judge (评价) them on attractiveness, health, and sleepiness,可知，他们让122个陌生人看了照片，并根据照片中的人的吸引力、健康程度和困倦程度对其进行了评价，但并没有让他们判断照片上的人是否有很多朋友，而没有提到辨别谁没有一些朋友。故选B。 53. 根据短文内容An unhealthy-looking face makes people run away. In other words, people don't want to hang around with people who might be ill.可知，陌生人不想和那些看起来不健康的人交朋友，由此得知他们是想和那些有魅力和精力充沛的人交朋友。故选D。 54. 根据短文内容An unhealthy-looking face makes people run away."可知，看起来不健康的人会把人吓跑，由此推知人们不愿意和那些疲倦的人交往，故socialize意为“交往”。故选C。 55. 主旨大意题。根据文章第一句Beauty sleep is a real thing, researches have shown that people who have enough sleep look more attractive(有魅力的) to others.可知，本文主要介绍了睡眠对我们的重要性，美容觉能让人看起来更有魅力，故A项“美容觉，更有吸引力”为本文最好的标题。故选A。 五、单词拼写（共10小题；每小题1分，共10分） 根据句意及汉语提示完成句子。 56.How terrible!

I got out of bed and turned it off. It was 6:30 in the morning, and I was very tired! It was very   (11)   outside, so I couldn't see anything! I walked over to the bathroom, took a shower and then I came out. I put all my books in my backpack so I wouldn't   (12)   them when I went to school. I went into the kitchen and ate the food my mother had cooked for me. But when I finished, my   (13)   still wasn't downstairs (在楼下) to drop me off at the school bus stop. Where was she? I went to my parents' bedroom and saw my mother   (14)  ! She must have gone back to bed! I woke her up and said, "I'm going to be late for school!" She looked at me and said, "Go and look   (15)  ." Confused(困惑的), I went to the window and opened the curtain(窗帘). It was lighter now and I could see outside.   (16)   I didn't see the green grass or the black road. Instead, I saw white everywhere. It was a snowy day, so there was no school! I ran to my mother. She got up and   (17)   me a jacket, boots and told me to play in the snow for a while. It was fun but really cold. I came inside after an hour. My dad was sitting at the table   (18)   two cups of hot chocolate and one was for me!

Control B People sometimes look at nature and fail to see its perfection. For example, they look at a plant and think, "How much better this plant would be if only   (21)   flowers were more beautiful!" Or they see a summer rain and think, "If I had created the world, I would have made it never rain when people are   (22)   vacation." Such was the case long ago when a traveler   (23)   under an apple tree. As he looked around, he saw a big pumpkin in a nearby garden. He noticed   (24)   the vine (藤）on which the big pumpkin grew was weak. Above him, he saw small round apples hanging on strong limbs (枝）. " (25)   silly nature is!" the man thought to himself. "If nature had half a brain, it would have made these big pumpkins   (26)   on this strong tree rather than on the weak vine." The traveler was   (27)   that he was smarter than the creator of all things in the natural world. Just then, a small apple fell from the tree, hitting the traveler on his   (28)  . He quickly saw the defect (不足之处）in his thinking. He   (29)   how things might have been different if it had been the huge pumpkin that had hit him on the head.

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 Nobe 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(克隆) of the adult frog. This technique later helped to create Dolly the sheep in 1996, the first cloned mammal(哺乳动物）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.” 36.Who won the 2012 Nobel Prize in Medicine? A. Sir John Gurdon B. Shinya Yamanaka. C. Sir John Gurdon and Shinya Yamanaka D. Gurdon’s science teacher. 37.In what order are the followings mentioned in the passage?     a. create the sheep Dolly b. take a cell from an adult frog c. use a person’s skin to create stem cells d. move a frog’s genetic information into an egg cell e. grow into a clone of a frog A. b—a—c—d—e B. b—d—e—a—c C. b—d—a—c—e D. b—e—d—a—c 38.What does the underlined word “ridiculous” mean? A. 无知的 B. 无畏的 C. 荒废的 D. 荒谬的 39.According to the passage, which statement is TRUE? A. As a boy, he was told he was hopeful. B. He ranked first at his high school in biology. C. It’s impossible for the doctors to repair a patient’s heart after a heart attack. D. In spite of his teacherˈs criticisms, he kept working hard. 40.What’s the main idea of the passage? A. Ninety percent of the time things don’t work. B. Luck favors the prepared mind C. Life is full of pleasure. D. How to know cells actually work. B Peng Jiangya, a 24-year-old girl, was born in Guizhou Province. She lives in a village of the Yinjiang Tujia and Miao Autonomous County(自治县)at the foot of the Fanjing Mountains on the Yunnan-Guizhou Plateau（高原）. Twenty-two years ago, One day her parents were out, she fell into a fire stove at home, and the fire burned her fingers badly. The family was too poor at the time to afford the expensive medical treatment ,at last she lost all her fingers. "When I was a child, I was unable to hold chopsticks. My parents taught me for a long time. It was really difficult, but I tried it over and over again ,and at the age of seven, I overcame it. From then on I knew that one had to put great efforts into what she was doing,” said PengJiangya. As a child , PengJiangya often saw others make cross-stitch (十字绣) and then she decided to learn how to make it herself. “ Of course, it took me many years to do that, when I was 18, I got it.” Said Peng. Now she can make as good cross-stitch works as her companions(同伴),but she is faster than other people. Her hometown of Yinjiang Tujia at the foot of the Fanjing Mountains on the Yunnan-Guizhou Plateauhas become a tourist attraction. As for her future, Peng Jiangya said: "I will gather a few other people to embroider(绣) the beautiful landscape of our hometown as a souvenir and lasting memory for tourists. At the same time, we can make more money." 41.Peng Jiangya was born            .

A. easily B. hardly C. with great efforts D. without any difficulties C On February 9th, 2013, Sarah Darling was walking along the street when she met a homeless man named Billy Ray Harris. She reached into her change purse, emptied out all the coins she had and gave them to the homeless man. Neither of them realized that this small generous act would change their lives. Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the following morning. She and her husband, Bill Krejci, rushed to see if they could find Billy. The homeless man was not only in the same place, he also immediately returned the ring. The grateful couple paid him back for his honesty by emptying out their pockets of all the money they had. Bill Krejci, a web designer, felt that he needed to do something more for this amazingly honest man. So on February 18th, he set up a special page to raise money for him. In just four days, Billy received over $85,000 and there seems to be no end yet. That is not enough. Billy is living with a person who is generous instead of living in the streets. And that's not all—thanks to the news report, he got together again with his older brother, Edwin Harris, who he had been unable to find for 27 years. All the good luck is just because Billy did the right thing—returning something that did not belong to him. 46.When did Sarah realize that she had also given Billy the diamond ring? A. On February 9th, 2013. B. On February 10th, 2013. C. On February 18th, 2013. D. On February 22nd, 2013. 47.Which of the following is NOT mentioned in the passage? A.

Edwin Harris. 50.What's the best title of the passage? A. Generous Woman Changed Her Own Life B. Kind Man Set Up Special Page C. Homeless Man Returned Diamond Ring D.
