Barbara McClintock was one of the most important scientists of the twentieth century. She made important discoveries about genes (基因) and chromosomes (染色体).
Barbara McClintock was born in 1902 in Hartford, Connecticut. Her family moved to the Brooklyn area of New York City in 1908. Barbara was an active child with interests in sports and music. She also developed an interest in science.
She studied science at Cornell University in Ithaca, New York. Barbara was among a small number of undergraduate students to receive training in genetics in 1921. Years later, she noted that few college students wanted to study genetics.
Barbara McClintock decided to study botany, the scientific study of plants, at Cornell University. She completed her undergraduate studies in 1923. McClintock decided to continue her education at Cornell. She completed a master's degree in 1925. Two years later, she finished all her requirements for a doctorate.
McClintock stayed at Cornell after she completed her education. She taught students botany. The 1930s was not a good time to be a young scientist in the United States. The country was in the middle of the Great Depression. Millions of Americans were unemployed. Male scientists were offered jobs. But female geneticists were not much in demand.
An old friend from Cornell, Marcus Rhoades, invited McClintock to spend the summer of 1941 working at the Cold Spring Harbor Laboratory. It is a research center on Long Island, near New York City. McClintock started a temporary (临时的) job in the genetics department. A short time later, she accepted a permanent position in the laboratory. This gave her the freedom to continue her research without having to teach or repeatedly ask for economic aid.
By the 1970s, her discoveries had had an effect on everything from genetic engineering to cancer research. McClintock won the Nobel Prize for Physiology or Medicine in 1983 for her discovery of the ability of genes to change positions on chromosomes. She was the first American woman to win an unshared Nobel Prize.
1.When did McClintock receive her doctorate
A.In 1921. B.In 1923. C.In 1925. D.In 1927.
2.What happened during the Great Depression in the US
A.Young female scientists might have trouble finding a job.
B.Female geneticists were not wanted at all.
C.Male geneticists were in great demand.
D.Even great scientists were out of work.
3.Why was McClintock awarded the Nobel Prize
A.Because of her research on botany.
B.Because of her discoveries about genes and chromosomes.
C.Because of her contribution to genetic engineering.
D.Because of her unshared work in the laboratory.
4.Where is the passage likely to appear
A.In a philosophy textbook. B.In a history paper.
C.In a travel brochure. D.In a biography.

Does just thinking about stepping inside a gym make you feel exhausted If so, here's some good news. One of the world's largest studies on physical activity has found that doing household chores (家务活) can be just as effective as running or working out when it comes to cutting your risk of heart disease and extending your life.
A team of researchers discovered that people enjoyed the same health benefits whether they were going to the gym, walking to work or doing household chores. Indeed, performing 30 minutes of any kind of physical activity a day, five days a week, could reduce your risk of dying from any causes by 28% and your rate of heart disease by 20%. And, again, the positive effects were the same whether someone was working out, walking or doing chores such as mopping the floor or gardening.
"Walking for at least 30 minutes most days of the week has a massive benefit, and high levels of physical activity is associated with even lower risk of illness," the lead researcher Scott Lear said about the findings. "By including low and middle income countries in this study, we were able to determine the benefit of activities such as having an active job or even doing household chores," Lear said. He noted that 1 in 4 people worldwide do not get 30 minutes of exercise a day, five times a week.
Interestingly enough, the Canadian study found no ceiling(上限) on the benefits of exercise and "no risks associated with extremely high levels of physical activity", defined as more than 2,500 minutes, or more than 41 hours per week. Lear said that those who spent more than 750 minutes walking quickly each week lowered their risk of premature death by 36%.
1.What can we infer about the study from Paragraph 1
A.Women should do more housework than men.
B.Doing housework may help to live long and healthily.
C.People with heart disease had better do less housework.
D.Doing housework makes people feel less tired than going to the gym.
2.What does Scott Lear say about his findings on health
A.Sitting long will take health away.
B.Exercise will make life meaningful.
C.It's a good idea to walk less than 30 minutes a day.
D.High levels of physical activity can reduce disease risk.
3.What is the study in the passage mainly supported by
A.Statistics. B.Voices. C.Examples. D.Experiments.
4.Which is the best title for the text
A.Take Exercise for Better Strength and Balance
B.Risks of High Levels of Physical Activity
C.Doing Household Chores May Be a Secret to Living Longer
D.Two Factors that Determine the Benefits of Activities
D
Climate change leads to a threat to the world's sandy beaches, and as many as half of them could disappear by 2100, a new study has found. Even by 2050 some coastlines could be unrecognizable from what we see today, with 10% to 12% facing severe erosion (侵蚀).
Using updated sea level rise predictions, the researchers analyzed how beaches around the world would be in the future with higher seas and more damaging storms. They also considered natural processes like wave erosion, as well as human factors ——like coastal building developments, all of which can affect a beach's health. The study found that the sea level rise is expected to outweigh these other factors, and that the more heat-trapping gases humans put into the atmosphere, the worse the influences on the world's beaches are likely to be.
It's hard to overstate just how important the world's beaches are. They cover more than one third of the world's coastlines, and protect coastal areas from storms. Beaches are also the important economic engine, supporting relaxation, tourism and other activities. And in some areas, the beach is more than a vacation destination. In places like Australia, life near the coast revolves around (以……为中心) the beach for much of the year.
Some of the world's most popular beaches are already taking action. Places like Miami Beach are trucking in thousands of tons of sand to patch up(修补) the badly eroded shoreline, while others have built sea walls and breakwaters in an attempt to hold precious sand in place. But the financial and environmental costs of these projects are huge, and scientists say rising seas and more powerful storms, supercharged by a warmer climate, will make this a losing battle.
However, the researchers did find that humans have some control over what happens to the world's beaches. If the world's governments are able to stick to modest cuts in heat-trapping gas pollution, the researchers found that a lot of projected beach losses by 2050 could be prevented.
1.Which may be the biggest contributor to severe beach erosion
A.Damaging storms. B.Wave erosion. C.Coastal buildings. D.The sea level rise.
2.What can we infer from Paragraph 3
A.It is hard to protect coastal beaches.
B.One third of storms break near beaches.
C.Beaches are of great significance to human life.
D.Most Australians live on beach tourism.
3.What does the underlined word "this" refer to in Paragraph 4
A.Popularizing the beaches. B.Holding sand in place.
C.Reducing the projects' costs. D.Stopping global warming.
4.What is the best title for the text
A.Half beaches could disappear by 2100
B.Climate change is doing harm to human life
C.The beach is more than a vacation destination
D.Governments are taking action to fight wave erosion

六、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
The moon was hanging low in the South Carolina sky as Misha finished loading her truck. Then she led Gandalf to his cage in the back. It was 3 a. m. on Tuesday March 20. Misha's husband Chuck came out to see her off. "Don't expect to go up there and find that lost boy in the woods, because it's just not going to happen," Chuck said. As a retired firefighter, he had seen more incredible things than a kid surviving three cold nights in the mountains, but he didn't want his wife to be disappointed in herself or her dog.
Three days earlier, 12-year-old Michael disappeared suddenly from his troop's campsite in Doughton Park. A massive search party had been sent out to find the boy that had been missing in the woods for three days, but there was barely a trace of the boy. They were about to lose hope when one dog named Gandalf, stepped in.
Misha and Gandalf, her two-year-old dog, had trained for a year with the South Carolina Search and Rescue Dog Association. But this was their first real job. Doughton Park was located in a bowl on the side of a mountain. It was covered with heavy forest, where slippery moss (苔藓) and waterfall spray threatened one's footing and thundering streams could drown out a child's cry for help.
Misha and her teammates arrived at the staging area around 7 a. m. on Tuesday, day four. The wind was coming toward them then around the shoulder of a cliff (悬崖). Gandalf was about 30 yards ahead, working on the bank of the stream where it turned beneath a wall of rock. Misha saw him quickly lift his head. Was that the sign she'd been waiting for Gandalf ran to the left, which was out of sight behind the cliff face. Misha tried to climb up the track behind him.
注意:续写词数应为150左右。
Paragraph 1:
All of a sudden came the bark of Gandalf.
_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Paragraph 2:
As it turned out, Michael's experience was tough.

二、答案：EGAFC
解析：本文是一篇说明文。研究发现参观公园会提升我们的幸福感。
①根据下文中的"spending 20 minutes in a city park can make you happier, whether you use that time to exercise or not可知,在公园里待20分钟就能让你更快乐,不管你是否利用那段时间来锻炼身体,故此处强调仅仅去公园就可以提高情绪健康(状况),结合选项可知,E项符合语境。
②根据空后的"Instead, we found time spent in the park is related to improved emotional well-being"可知,相反,我们发现在公园里度过的时间与情绪健康(状况)改善有关,故可推知,空前表示的是另外一种情况,即"我们没有发现体育活动级别与情绪健康(状况)改善有关",故G项符合语境。
③根据空后的"A visit of between 20 and 25 minutes showed the best results"可知,20到25分钟的参观显示出最好的结果,故空前应说明调查的过程,故A项"有一些东西被用来追踪他们的体育活动"与上下文联系紧密,符合逻辑。
④根据上文内容可知,20到25分钟的参观显示出最好的结果,参与者的幸福感增加了约64%,即使他们在公园里不怎么运动。F项"这意味着人们可以从参观附近的公园中受益,无论他们的体能如何"是对上文的调查做出的总结,并与第二段中的研究结果相呼应。故F项符合逻辑。
⑤根据空前的"The study group was truly small, as the study's co-author and another UAB professor, Gavin Jenkins, admitted"可知,正如研究报告的合著者——UAB的另一位教授Gavin Jenkins所说的那样,研究小组的规模确实很小,而空后则指出了当前城市面临的挑战,结合选项可知,C项"然而,它的发现指出了城市公园的重要性"承接上下文。
三、答案：1-5.DCBCB; 6-10.DCADB; 11-15.CBDAC
解析：1.根据下文可知,此处是说Fritz Kreisler偶然遇见了一把小提琴,想把它买下来。
2.根据上下文可知,Fritz Kreisler当时没有钱买那把小提琴,最后终于凑够了钱才回去买它。
3.上文说Fritz Kreisler十分想买那把小提琴,下文中提到收藏家坚持不卖小提琴的细节,由此可知,此处是说Fritz Kreisler试着说服收藏家把小提琴卖给他。
4.由上下文语境可知Fritz Kreisler希望收藏家能把小提琴卖给他,而收藏家却说那把小提琴是他宝贵的财产之一,前后句之间是转折关系,故选C项。
5.由收藏家没有将小提琴卖给购琴心切的Fritz Kreisler可知,Fritz Kreisler应该会感到失落,所以应选B项。
6.根据上下文内容可知,Fritz Kreisler喜欢这把小提琴却又得不到它,所以请求在小提琴被收起来之前用这把小提琴再演奏一次。
7.由语境可和,此处是说Fritz Kreisler用小提琴演奏出了美妙的音乐。
8.根据下文中的"The violin is yours, Mr Kreisler."可知,收藏家听完Fritz Kreisler的演奏之后认为他自己没有权利继续拥有那把小提琴了,所以把它送给了Fritz Kreisler。
9.根据上下文的内容可知,收藏家希望更多的人能听到小提琴的美妙音乐。下文中的"our 14 is meant to be heard"也是提示。
10.由空前的"For you and I are excellent violins"可知,应选B项。
11.由下文中的"it is found in applying our lives to helping others"以及"My life is meant to be lived"可知,应选C项。
12.根据上文中的"live it fully"可知,作者希望自己的生活充实一些,宁可终日繁忙也不愿虚度年华。use up意为“用尽,用光”。
13.作者在此进一步解释了自己的观点,他所说的“充实地生活”并不是指做很多的事情把自己弄得疲惫不堪。exhaust意为“使疲惫不堪”。
14.根据上文中的"applying our lives to helping others"以及下文中的"charity organization"可知,此处是指自愿做。
15.根据上文中的"applying our lives to helping others"可知,此处作者重申主题——幸福不在于我能做什么或不能做什么,而在于我能给予别人多少。give意为“给予”。
四、答案：an; prevention; out; but; treating; remarkable; to overcome; was awarded; to; its
解析：本文是一篇说明文,主题语境为人与社会。文章介绍了中国工程院院士、著名呼吸病学专家、全国呼吸感染性疾病防治领军人物——钟南山。
①考查冠词。句意:钟南山,一位85岁的人,也是一名中国工程院院士,著名呼吸病学家,中国呼吸传染病防治领军人物。此处作Zhong Nanshan的同位语,泛指“一位85岁的人”,应使用不定冠词,85-year-old的发音以元音音素开头,故填an。
②考查名词。此处与and后的control是并列成分,作介词in的宾语,应使用名词,为抽象意义,且不可数,故填prevention。
③考查固定短语。句意:2003年春天,中国和世界各地暴发了非典疫情。根据句意可知,此处使用固定短语break out,故填out。

六、答案：
Paragraph 1:
All of a sudden came the bark of Gandalf. When Misha heard that, she immediately climbed over the track and looked around. At first, she saw Gandalf was walking back and forth around a rock. Misha went over and saw Michael, who got injured. His right leg was trapped under a stone. He looked weak and unconscious. Then Misha immediately called on her teammates to save Michael. They removed the stone on Michael's leg and sent him to the nearest hospital.
Paragraph 2:
As it turned out, Michael's experiernce was tough. After treatment, he came around. Then he told them what had happened to him in the forest. A few days ago, he was playing around the campsite when he saw a beautiful butterfly flying around. He tried to catch the butterfly and chased after it, only to find he was lost. He slipped and his right leg was trapped under the stone when he was looking for his way back. Fortunately, it was Gandalf, Misha, and Misha's teammates who saved him. He said he would appreciate that forever.
