Growing up, Deka Ismail says she let labels define what she could be. “I was a black girl, from a refugee (难民) family,” Deka said. “It was as if I was only allowed to explore in this predetermined
box.”
After a high school chemistry class inspired her to think about a career in science and gave her confidence in the field, Deka learned to live outside labels and began making big plans for her future. Now she is about to begin her freshman year at the University of California, planning to become a professor.
Born and raised in San Diego’s City Heights neighborhood, Deka is the daughter of a Somali refugee couple. When Deka was eight years old, her mother got a job by studying hard back in school in order to support the whole family. That made Deka realize that education could make a difference to one’s life. She spent a lot of time in the library reading books, and didn’t do many of the things her peers did, like partying or having romantic relationships.
“I always felt like I had to be the perfect girl for my family,” Deka said. “You have to do your best and do much better than everyone else. I felt like the whole world was waiting for me to mess up.”
Deka’s efforts paid off. The summer before her senior year of high school, she was accepted to the American Chemical Society Project SEED Programme. “She brought both enthusiasm and focus,” Botham, a researcher at this research institute, recalled. “She arrived every day ready to work, ready to learn and ready to tackle new challenges regardless of whether or not she had done anything similar.”
When asked what advice she would give to others like her, Deka warned them not to underestimate themselves. “Don’t tell yourself that scholarship is too big or this programme is too competitive or I’ll never get into this school,” she said. “I was not sure whether I could make it until
I started seeing the acceptance letters rolling in.”
24. From the passage, we can learn that ______.
A. Deka was adopted by a refugee family.
B. Deka became a professor after graduation.
C. Deka’s experiences drove her to work hard.
D. Deka spent a lot of time going to parties.
25. Deka realized the importance of education ______.
A. after her chemistry class
B. from her mother’s experience
C. by reading books in the library
D. through working at the institute
26. According to the last paragraph, Deka advised that students be ______.
A. patient
B. ambitious
C. confident
D. generous
27. What does the story intend to tell us?
A. Life is not all roses.
B. Practice makes perfect.
C. Well begun is half done.
D. Hard work leads to success.
C
The worst outbreak of desert locusts (蝗虫) in decades is presently underway in the Horn of Africa. It is the biggest of its kind in 25 years for Ethiopia and Somalia – and the worst Kenya has seen for 70 years.
What we are seeing in East Africa today is unlike anything we’ve seen in a very long time. Its destructive poten tial is enormous, and it’s taking place in a region where farmers need every gram of food to feed themselves and their families. Most of the countries hardest hit are those where millions of people are already vulnerable (脆弱的) or in serious humanitarian need, as they endure the impact of violence, drought, and floods.
We have acted quickly to respond to this outbreak. The primary method of battling locusts is the aerial spraying of pesticides (杀虫剂). FAO’s “Locust Watch” service explains that “although giant nets, flamethrowers, lasers, and huge vacuums have been proposed in the past, these are not in use for locust control. People and birds often eat locusts but usually not enough to significantly reduce population levels over large areas.”
The UN’s Office f or the Coordination of Humanitarian Affairs has released $10 million from its Central Emergency Relief Fund to fund a huge scale-up in aerial operations to manage the outbreak.
But the window to contain this crisis is closing fast. We only have until the beginning of March to bring this infestation under control as that is when the rain and planting season begins. If left unchecked – and with expected additional rains – locust numbers in East Africa could increase 500 times by June.
We must act now to avoid a full-blown catastrophe. And we will. At the same time, we need to pay attention to a bigger picture. This is not the first time the Greater Horn of Africa has seen locust outbreak approach this scale, but the current situation is the worst in decades. This is linked
to climate change. Warmer seas mean more tropical storms, generating the perfect breeding conditions for locusts.
28. What is implied in paragraph 2?
A. People in East Africa are going through floods.
B. The locust outbreak is worsening locals’ life.
C. People in East Africa are suffering drought.
D. The locust outbreak will cause crop failure.
29. What can we learn from the last paragraph?
A. It is the largest outbreak of locusts ever in history.
B. We need a bigger picture to study the disaster.
C. The outbreak of locusts is fueled by global warming.
D. It is the second outbreak of locusts in East Africa.
30. What is the purpose of the text?
A. To introduce and assess.
B. To argue and discuss.
C. To analyse and compare.
D. To inform and call for.
31. Where does the text probably come from?
A. A news report.
B. A health magazine.
C. A chemistry paper.
D. A guidebook.
D
Scientists say they have developed a system that uses machine learning to predict when and where lightning will strike. Researchers report the system is able to predict lightning strikes up to 30 minutes before they happen within a 30-kilometer area.
Lightning is a strong burst of electricity in the atmosphere. Since it carries an extremely powerful electrical charge, it can be destructive and deadly. European researchers have estimated that between 6,000 and 24,000 people are killed by lightning worldwide each year. For this reason, climate scientists have long sought to develop methods to predict lightning.
The system tested in the experiments uses a combination of data from weather stations and machine learning methods. The researchers developed a prediction model that was trained to recognize weather conditions that were likely to cause lightning.
The model was created with data collected over a 12-year period from 12 Swiss weather stations in cities and mountain areas. The data, related to four main surface conditions: air pressure,
air temperature, relative humidity and wind speed, was placed into a unique machine learning algorithm (算法), which compared it to records of lightning strikes. Researchers say the algorithm was then able to learn the conditions under which lightning happens.
The researchers test-ran the system several times. They found that the system made predictions that proved correct almost 80 percent of the time. “It can now be used anywhere,” the Swiss Federal Institute of Technology said in a statement.
The researchers plan to keep developing the technology in partnership with a European effort that aims to create a lightning protection program. The effort is called the European Laser Lightning Rod project. Scientists working on the project are experimenting with a laser technology that could someday control lightning activity, transferring lightning charges from clouds to the ground. They hope that such technology can one day be used as protection against lightning strikes. Possible uses could be at stations, airports or places where large crowds gather.
32. Why was the system developed?
A. To show the power of lightning.
B. To meet kids’ curiosity about lightning.
C. To protect people from lightning.
D. To keep track of lightning deaths.
33. What is special about the system?
A. It adopted a different machine learning algorithm.
B. It used an effective method of collecting data.
C. It was based on a number of samples worldwide.
D. It required low cost of predicting lightning.
34. What will the researchers do next with the laser technology?
A. Generate electricity with lightning.
B. Direct energy from lightning.
C. Monitor lightning activity.
D. Prevent the occurrence of lightning.
35. What can be a suitable title for the text?
A. A Theory of Employing Lightning
B. A Model of Creating Lightning
C. A System of Controlling Lightning
D. A Method of Forecasting Lightning

Competition is a common phenomenon in our social life. 36 There is constant competition for academic degrees, jobs, customers, money and so forth. In a sense, competition is
one of the motive forces to the development of society.
37 Therefore, the only way to survive is to be competitive. Growing in a competitive environment is important for a child because future adult life is difficult. Finding a good job, for example, is an extremely competitive activity.
Today, most people obtain knowledge through various ways and a large number of people get good education. 38 The quality of people is rapidly increasing. Competition is more violent than what we thought it should be. The potentially successful job applicant has to be prepared in stronger position by gaining more qualifications and experience. In the sports contests, the strongest will come out as winners. In the business world, to beat your competitors, you must be better than the other employees. 39
Though the only way our world rewards people is to give honor to the winners, not to the losers, by attempting to compete at different activities, we can still learn to win and lose, gain experience and know our strengths and weaknesses. Competition prepares us for the tough things in life.
Whether in games, in study or in business alike, the aim is to win the game, the degree, the trophy, and the contract. 40
A. Modern society demands high-quality talents.
B. Otherwise, you will be defeated.
C. Learning to be competitive is clearly the best preparation for life.
D. There are also many people who have higher degrees in their special fields.
E. Children have to learn to be competitive in order to adapt to modern society.
F. We compete when we play games and when we try to do better than others in our study.
G. In the natural world, the weak will be replaced by the strong and the fittest can live.

A Colorado pair brings new meaning to the word “determination”. When one couldn’t walk and the other couldn’t see, they41 up to share their love of the great outdoors.
Melanie Knecht has to use a wheelchair to get around due to born spina bifida (脊柱裂). Trevor Hahn only recently became blind after he 42 an eye disease five years ago. Both living in Fort
Collins, Colorado, the two met at an adaptive boxing class — and they soon ran into each other again at an adaptive rock-climbing class.
They immediately 43 over Knecht’s lifelong hobby of camping and Hahn’s p assion for outdoor sports. When she told him about her recent trip to Easter Island, where she got the 44 to be carried on another person’s back, an unusual idea occurred to her.

“It just seemed like common sense. He’s the legs, I’m the eyes!48 , we’re the dream team.” said Knecht.
At the start of each hike, a friend lifts Knecht 49 a carrier on Hahn’s back. From that point on, she gives him oral directions to lead the way.
Hahn said, “It made me so happy to help someone experience what I’ve been able to exp erience my whole life. The best part is being able to make her smile—that gives me 50 .”
In addition to this sense of purpose, the two share an understanding of how 51 it can be asking able-bodied or sighted people for assistance in everyday life. They get immeasurable 52 from being able to do this on their own.
While the two accept that others 53 what they’ve been able to do, they’re not looking for 54 —they just want others to encourage solutions for their friends with disabilities. Don’t 55 them because you think they won’t be able to do something.

Alexis Vaughan, 17, sat quietly in the passenger seat of her dad's car. She stared out the window at the Preston, Idaho, cornfields.
Alexis, a high school student, let her eyes lazily scan the landscape for wildlife. Still, she was terrified when a deer came into view about 200 yards in front of them, just a few feet off the road. "Dad, there's a deer, there!" Alexis said, rolling down the window for a better look. It was a three-point buck(雄鹿) --a male deer with sharp, three-pronged antlers (角) on each side of its head．As the car moved closer, Alexis saw that the buck's head was bent toward the ground．Then she heard a scream. A few seconds later, she saw an arm fly up near the buck's head．Alexis realized the buck was attacking a woman. Sue Panter, a 44-year-old mother, had been out for her morning run. The buck had come out from the tall corn and began following her. Having lived in rural Idaho for years, Sue knew that most bucks got frightened by humans. But this buck edged closer, even when she threw at it with a handful of gravels(石子).
Sue went to pick up a log to use for self-defense, and the buck charged．It lifted her with its antlers and threw her into the air. Sue could feel the horns punctured(刺穿) her leg and blood flowed down her leg．Within seconds, the buck had pushed her off the road and into the cornfield.
When Alexis and her father pulled up, the buck was rolling Sue like a rag doll．Alexis looked into the woman's terrified eyes, and before her father had even stopped the car, the 104 pound teenager jumped quickly out of the car and down the slope （斜坡）toward the buck. She was kicking and hitting it to get its attention. Then Michael, her father, who had followed his daughter, wrestled the buck away from the women by holding the antlers.
Paragraph1: Alexis helped Sue up the slope. ___________________________________________

Dear Tom,
How is everything going? I'm delighted to know you're coming to China to learn Chinese paintings, hoping to take a short course in my city.
An art school, which is located in the center of the city, is the best choice for you. As I've learned, you'll finish studying Chinese ink landscape painting in six weeks. What's more, you can both eat and live in the school while studying here. Therefore, you needn't worry about your accommodation. In addition, the school charges a relatively modest fee.
If you have any other questions, please write to me as soon as possible.
Yours,
Li Hua

Alevis helped Sue up the slope. With all her strength, she immediately seated her into their car, and then applied a clean towel from her bag to Sue's right leg tightly, which would help to stop its bleeding. Sue was covered with wounds from head to toe and she was in rags（衣衫褴褛) because of the severe attacks. Apparently Sue was too shocked by the accident to let out a word. Alexis talked softly to comfort the terrified woman and thought about how to help her father Then she heard her father yell. Michael had been knocked to the ground, his right leg speared
（刺）by the buck. Alexis grabbed a hammer from the car and ran to where Michael lay on his back in the dirt. She beat the bucks head and neck, but the blows didn't work. Standing over her father, Alexis could see that he was struggling to breathe. Turning the hammer around, Alexis squeezed her eyes shut and hit the buck's neck. When she opened her eyes, the buck was running away. Alexis got in the driver's seat and sped toward the hospital.

高二下学期期中考试总结 紧张的考前复习，压制神经的考试，下考场后的议论纷纷，有人欢喜有人忧。全县统考结束后顿时感受轻松了不少，暂且别去说考试成绩的好坏，至少这种感受让人感到发自心里的放纵。随后而来的便是对考试成绩的焦急等待和新一轮学习的开始...也许以我这次的考试成绩并别能说成是优异，能够说算个中等吧。但关于我个人来说这也是一具进步，尽管有几科成绩别尽人意。下面就仔细分析分析吧。 先说说英语和历史吧。总体来说进入高中以来我的英语成绩呈现直线下滑趋势，这次也毫别出意外的只考了87分。我很清晰的知道考低分的原因:寻常老师让默写单词时别写，让记语法时别记。一到考试的时候就开始发愁，特别是在做单项挑选题的时候，单词疑惑什么意思感受哪个选项都对，语法疑惑如何运用感受哪个选项基本上答案，结果惟独乱猜了，这次考试在这方面就吃了大亏了。历史这科自我感受依然挺简单的，因为上次考试还得了80多分呢，我想的是这次至少能够考85分的，结果特别完美的验证了一具词语:眼高手低。成绩下来只考了66分。尽管说这次全校历史成绩都有所下滑，但是得高分的依然有的。这次历史成绩给了我别小的打击，更何况老班是算是由历史老师，的确有点别给他面子了。寻常历史学的还挺卖劲的，对历史也是有浓厚的兴趣的，可考试怎么说是考试，后面的非挑选题都是基本上只得了一半的分，未来可得注意了。再说说政治吧。说句实话《日子与哲学》这一册的知识比较难理解，寻常的学习也不过死记，全然别太理解其中的含义，寻常做练习题也别注意总结，结果考试的时候后面的咨询答题都是是胡写的，想到哪一点就写哪一点，没有头绪没有要点。有因必有果:有两个大题别得分，有一大题只得了一分，在整张卷子上拉了将近30分，尽管挑选题做的还能够，但分数也都是定格了，只考了59分。看看分数再想想自己在课堂上的表现:睡觉，发呆...特别是老师说练习题的时候都是是别听的，以至于对张老师说的咨询题分析、做题思路都毫无印象，考试的时候为所欲为，乱答一气。如今终于知道自己有多笨了，真懊悔。 数学和语文成绩小有进步。语文就别用说了，数学可是个难题。说句实话，数学有25分的挑选题别是我自己做的，后面的大题自己苦心专研的。自认为很简单的，结果很别爽的有两道大题别得分。挑选题在别人的热心帮助下错了两道，还别错。事实上，这段时刻可没少在数学上下功夫，终于功夫别负有心人得了92分。语文得了115分，我最开心的是语文没有低于110分过，但成绩还有待更进一步。最后说说地理吧。事实上高一上学期学自然地理的时候，我的地理成绩依然一踏糊涂，但在这种极其惊险的事情下，我依然毅然挑选了文科。为了补瘸腿科，我对地理学习也分外的努力。高一下学期是人文地理，比较简单，渐渐的我的地理成绩也有所上升。事实上能有如此的成绩和地理老师和老师是分别开的。刚开始学习地理的时候我别敢向老师咨询题，也从来没有咨询过。高一下学期和老师开始带我们班地理之后这种事情才有所改变，渐渐的也就没有什么胆怯的了。时刻长了对地理也产生了浓厚的兴趣。这对我将来的学习产生了很大的妨碍。这次地理成绩还算理想，考了83分。我想这与我平时的训练是分别开的，特别是考试前对基础知识的复习和对往常做过的练习题的复习，但是挑选题错的太多，错了5道，都是好基本上寻常老师说过的，真别应该。总体上来说，这次考试题别算太难。但由于自己的粗心大意依然吃了很多亏。未来一定要注意。 别管如何样，这次考试差不多结束了，成绩的好坏也差不多成了定局。但它只能代表过去，别能对自己的以后做判决。这次考试给了我很大的启示，也让自己看到了自己的缺点与别脚，有了这次的考试经验，将来我一定注意改正自己在学习中的缺点，弥补自己的别脚，争取再创一具更好的成绩！ 命运如同手中的掌纹，不管再如何蜿蜒但终究在你手中。要知道，没有等出来的漂亮，惟独拼出来的辉煌！
