　　2017西安市高考英语三轮冲刺选练4 阅读理解。Once, the Paiter-Surui tribe(部落)lived a happy life in the heart of the Amazon rainforest in Brazil. But after the tribe’s first meeting with Westerners several decades ago, they were nearly wiped out; diseases brought by outsiders reduced the Surui’s numbers from 5, 000 to about 250. Today, some 1, 300 tribe people live in 23 villages across 600, 000 acres. Though they are as likely to wear T-shirts and jeans as feathered headdresses, the Surui are determined to preserve and protect the tribal culture of their homeland. Now they are under threat again, from illegal logging and deforestation(滥伐), but this time it’s different. The Surui have put aside their bows and arrows and taken up a new weapon: the Internet. The tribe people learned to use the Web from their leader, Chief Almir Narayamoga. “We decided to use computers and technology to bring attention to our situation, ”says Narayamoga, 36. The first in his tribe to attend college, Chief Narayamoga learned how to use computers at the Federal University of Goiás in Goiânia, a city of 1. 2 million. In 2007, he fled the Surui homeland after his fight against loggers who placed a $100, 000 reward on his head. He traveled to the United States and paid a visit to Google headquarters in California. He came armed with a big idea. Narayamoga’s visit to Google was considered a great success. And Google sent teams to the Amazon to train the Surui in using computers, cameras, and smart phones to photograph logging sites, which could be pinpointed using GPS technology and then uploaded to Google Earth. The Surui have now mapped the entire reserve and recorded the biodiversity and the rainforest within it. 【文章大意】本文主要讲了巴西土著居民正在利用因特网让世人知道他们的处境, 并开始保护他们的家园。 1.

A．A study indicates that women arrived in America around 20,000 years ago． B．A study indicates six women gave rise to migrants of America． C．A DNA study tells about people who crossed into North America from Asia． D．A study indicates Native Americans can trace their ancestry to just six women． 7．Which of the following is TRUE about the research? A．It shows that DNA is passed from parents to daughters． B．It concludes that the six women arrived individually but lived at the same time． C．It is a joint one conducted by Salt Lake City and an Italian university． D．It shows that only six women in 95% of present Native Americans have got a particular DNA legacy． 8．Which of the following has the closest meaning to the underlined word “lineages”? A．Classes． B．Varieties． C．Families． D．Findings． 9．What didn’t Ugo Perego and his team do? A．They used a “family tree” to analyze the findings． B．They focused on life styles of the original women． C．They clarified genetic changes in the family tree． D．They studied how long each branch had developed． 10．What can we infer from the finding? A．The six mothers probably lived on the present islands in North America． B．Most Native Americans have got the DNA legacy passed from the six women． C．Beringian DNA was found in the women who originally immigrated to North America． D．The research was not accepted by the previous scientists because of its contradiction．【参考答案】6—10、 D C C B B 阅读理解。 Everyone knows about straight-A students．We see them frequently in TV situation comedies and in movies like Revenge（报复）of the Nerds．They get high grades, all right, but only by becoming dull laborers, their noses always stuck in a book．They are not good at social communication and look clumsy while doing sports． How, then, do we account for Domenica Roman or Paul Melendres? Roman is on the tennis team at Fairmont Senior High School．She also sings in the choral group, serves on the student council and is a member of the mathematics society．For two years she has maintained A’s in every subject．Melendres, a freshman at the University of New Mexico, was student-body president at Valley High School in Albuquerque．He played soccer and basketball well, exhibited at the science fair, and meanwhile worked as a reporter on a local television station．Being a speech giver at the graduation ceremony, he achieved straight A’s in his regular classes, plus bonus points for A’s in two college-level courses． How do super-achievers like Roman and Melendres do it? Brains aren’t the only answer．“Top grades don’t always go to the brightest students, ” declares Herbert Walberg, a professor of education at the University of Illinois at Chicago, who has conducted major studies on super-achieving students．“Knowing how to make the most of your innate（天生的）abilities counts for more．Much more．” In fact, Walberg says, students with high IQ sometimes don’t do as well as classmates with lower IQ．For them, learning comes too easily and they never find out how to get down． Hard work isn’t the whole story, either．“It’s not how long you sit there with the books open, ” said one of the many-A students we interviewed．“It’s what you do while you’re sitting．” Indeed, some of these students actually put in fewer hours of homework time than their lower-scoring classmates． The kids at the top of the class get there by mastering a few basic techniques that others can readily learn． 11．The underlined word “nerds” can probably be ． A．dull bookworms lacking sports and social skills B．successful top students popular with their peers C．students with certain learning difficulties D．born leaders crazy about social activities 12．What can we conclude from the first paragraph? A．Most TV programs and films are about straight-A students． B．People have unfavorable impression on straight-A students． C．Everyone knows about straight-A students from TV or films． D．Straight-A students are well admired by people in the society． 13．Some students become super-achievers mainly because ． A．they are born cleverer than others B．they work longer hours at study C．they make full use of their abilities D．they know the shortcut to success 14．What will be talked about after the last paragraph? A．The interviews with more students． B．The role IQ plays in learning well． C．The techniques to be better learners． D．The achievements top students make． 15．What can we infer from the passage? A．IQ is more important than hard work in study． B．The brightest students can never get low grades． C．Top students certainly achieve all-around developments． D．Students with average IQ can become super-achievers．【参考答案】11—15、A B C C D （2017陕西卷）假定你是中学生李华。美国一个中学校长代表团即将访问你校并出席英语周的一项活动。请根据写作要点和写作要求写一篇欢迎词。 写作要点： 1.表示对客人的欢迎； 2.介绍此项活动（如活动目的、内容等）； 3.表达对客人的祝愿。 写作要求： 1.词数不少于100； 2.称呼已经给出，请写欢迎词正文； 3.不能使用真实姓名和学校名称。 Dear American guests, _____________________________________________________________________ 【考点】考察提纲类作文【写作指导】本文属于提纲类作文。美国一个中学校长代表团即将访问你校并出席英语周的一项活动，你作为李华要写一篇欢迎词。所以使用一般现在时，和第一人称。要点：1.表示对客人的欢迎；2.介绍此项活动（如活动目的、内容等）；3.表达对客人的祝愿。本作文中给出的要点比较具体,故需要准确表达.写作时注意准确运用时态，上下文意思连贯，符合逻辑关系，尽量使用自己熟悉的单词句式，同时也要注意使用高级词汇和高级句型使文章显得更有档次。特别注意在选择句式时要赋予变化。【一句多译】这个活动的目的是发展我们学习英语的兴趣并提高我们听说英语的能力。（1）The purpose of this program is to develop our interest in English learning and practical abilities in listening and speaking. （2）It is the purpose of this program to develop our interest in English learning and practical abilities in listening and speaking. 【参考范文】 Dear American Guest, On behalf of our school, I would like to express our warm welcome to you.
