Ⅱ.阅读理解
A
Over the summer,18­year­old Roberto Mancera of Chandler wasn’t looking forward to dances，football games or even his last year in high school.He was more excited about building a robot that will compete in the sixth annual FIRST Robotics Competition (FRC)Arizona Regional.
FIRST stands for For Inspiration and Recognition of Science and Technology，a non­profit organization that believes the heroes of today’s youth should be engineers，not sports or pop stars.They aim to change the culture by hosting athletic­like competitions for robots，with cheering fans，mascots(吉祥物) and music.
Mancera and a team of about 14 of his schoolmates will compete this year against 44 other high school teams from all over Arizona，California and New Mexico at the Arizona Veterans Memorial Coliseum in Phoenix.Finalists will move on to the FRC 2009 Championship in Atlanta to face teams from 48 states and seven other countries.
For the 40 regional events worldwide，a similar “kit(工具包)of parts” is given to each of the 1,680 teams from around the globe every January.The robot functions are different every year，and after a six­week building season，robots are boxed up and shipped off to the competition’s destination.
The competition has a minimum $6,000 entrance fee，and students are sponsored and mentored by adult professionals and experts，like computer science teacher Sam Alexander,39，at Chandler High.“I try to give the kids the challenge and they try to figure it out，” he said.“They work through the entire scientific method without me giving them the answers.”
FIRST students are also eligible(有资格的) to apply for $9.7 million in college scholarships，something that Alexander’s students have taken advantage of.
“You learn skills that your average student isn’t learning，” Mancera said.“It’s really amazing，and I’ve been able to meet a lot of interesting people.” Mancera said that he found himself when he joined the robotics team.He now has a career goal set and has learned valuable leadership skills.
1．The goal of FIRST is to________.
A．help students have a rich summer
B．choose heroes for today’s youth
C．develop the interest of young people in sports
D．create a culture of valuing technology
答案　D
解析　事实细节题。根据第二段的“They aim to change the culture by hosting athletic­like competitions for robots...”可知答案为D项。
2．Each robot made for the competition is________.
A．designed for a different function
B．decorated similarly
C．a team­made product
D．a copy of famous robots
答案　C
解析　推理判断题。根据第三段的“Mancera and a team of about 14 of his schoolmates...” 可知，参赛机器人是团队制作的产品。
3．Which of the following words has the similar meaning to the underlined word “mentored” in Para.5?
A．Guided. B．Controlled.
C．Judged. D．Replaced.
答案　A
解析　猜测词义题。根据第五段中“students are sponsored and...by adult professionals and experts”可知专家们赞助并指导参赛学生。
4．What’s the influence of FIRST on Roberto Mancera?
A．He has been awarded a college scholarship.
B．He has become the hero for his classmates.
C．It has helped him to decide his future career.
D．It has allowed him to make a lot of friends with the same interest.
答案　C
解析　事实细节题。根据最后一段的“He now has a career goal set...”可知答案为C项。
B
Scientists studying the impact of climate change on the Arctic need to consider ways to reduce their own carbon footprints(碳排放量)，says Ryan Brook，a researcher who regularly flies north to study the health of caribous(驯鹿)．He calls on scientists to show leadership by examining and sharing ways to reduce the impact of working in polar regions.
“The importance of the research is not at question here. It is important to our understanding of and adapting to climate change.But we need to think about better approaches，” says Brook.
“This is an issue for all scientists，though polar researchers often travel particularly long distances using commercial air travel.We also rely extensively on small aircraft，icebreakers，and snowmobiles，all of which produce large amounts of carbon.”
Brook studies the health of caribou herds in Nunavut and Northwest Territories.He works with northern wildlife managers.This work typically takes him north five or six times per year and when he calculated his own carbon footprint，he was not happy with the result.
“My research footprints are about the same as the annual footprints of an average Toronto resident.Basically，I have two footprints—my own personal life，which is moderate，and my research footprint.”
Climate scientists can rightly argue that Arctic research is a specialized field and the community of scientists who travel north is relatively small.Even if all scientists working in the north reduced their carbon emissions，it would not make a big impact on the global scale.For Brook，it’s the option that matters.
There are ways researchers can reduce the amount of carbon they use.Some helicopters use less fuel than others.Solar and wind power are alternatives to gas­fired generators.And while carbon offsets(抵消) don’t reduce the amount of carbon emitted，they are an easy first step.
“There aren’t necessarily any easy answers，but we need to start talking about it，”says Brook.“This is particularly important for the next generation of scientists being trained and I hope to see them become leaders in this issue.”
5．The underlined word “It” in Para.2 refers to________.
A．the research of climate change on the Arctic
B．the study of the health of caribous
C．the impact of working in polar regions
D．the reduction of polar scientists’carbon emissions
答案　A
解析　代词指代题。根据“The importance of the research is not at question here.It is important to our understanding of and adapting to climate change.”(这项研究的重要性不言而喻。它对我们理解并适应气候变化很重要)可知“It”指：对北极气候变化的研究工作。
6．What did Brook find when he calculated his own carbon footprints?
A．His carbon footprints are more than the annual footprints of a Toronto resident.
B．His personal life footprints are more than the annual footprints of a Toronto resident.
C．His research footprints are about the same as his personal life footprints.
D．His personal life footprints are more than his research footprints.
答案　A
解析　推理判断题。根据第五段的“My research footprints are about the same as the annual footprints...I have two footprints—my own personal life...and my research footprint.”可知Brook的carbon footprints(personal life footprint＋research footprint)比“the annual footprint of an average Toronto resident”多。
7．We can infer from the last paragraph that________.
A．we should take actions immediately instead of just talking
B．it’s easy to start talking about the problem of carbon emissions
C．it’s necessary now to pay attention to the problem of research footprints
D．the next generation of scientists are more interested in research footprints
答案　C
解析　推理判断题。根据最后一段的“...but we need to start talking about it...”可知答案为C项。
8．What’s the main idea of the text?
A．The importance of arctic research is not at question.
B．Climate change becomes worse because of arctic research.
C．Brook suggests ways of reducing the use of carbon.
D．Scientists must look at their own carbon footprints.
答案　D
解析　主旨大意题。本文主要介绍了一位科学家通过关注自己在北极地区研究时所产生的二氧化碳问题，从而提出了所有的科学家在北极地区工作时，要注意自己产生的碳排放的问题。

沁园春·雪 <毛泽东>
北国风光，千里冰封，万里雪飘。
望长城内外，惟余莽莽；
大河上下，顿失滔滔。
山舞银蛇，原驰蜡象，
欲与天公试比高。
须晴日，看红装素裹，分外妖娆。
江山如此多娇，引无数英雄竞折腰。
惜秦皇汉武，略输文采；
唐宗宋祖，稍逊风骚。
一代天骄，成吉思汗，
只识弯弓射大雕。
俱往矣，数风流人物，还看今朝。
希望的灯一旦熄灭，生活刹那间变成了一片黑暗。——普列姆昌德

薄雾浓云愁永昼， 瑞脑消金兽。 佳节又重阳， 玉枕纱厨， 半夜凉初透。
东篱把酒黄昏后， 有暗香盈袖。 莫道不消魂， 帘卷西风， 人比黄花瘦。
