Ⅰ.阅读理解
As a kid, Joanna Buckley wasn't interested in science — until she had a chance to try it. That happened when she got a chemistry set for Christmas.
“Over the course of a few weeks, I'd completed every experiment. But in the process, I polluted my parent's dining room carpet and burnt the kitchen worktop with the spirit burner，” she says.
Now science is Buckley's job. She works in the chemistry department at the University of Sheffield in England. “I realize, firsthand, how important it is to have something or someone to show you why science is so great，” she says. Now the good news is that citizen science appears.
Citizen science takes the fun of experimenting a step further than Buckley's athome chemistry kit. That's because these experiments are real, looking for novel answers.
“Compared with a oneoff experiment, what's cool about citizen science is that students get that this has a purpose，” Prunuske says. “Students want to do a good job, because they know scientists are going to use the new data in their own research.”
Long agrees. “Kids like that it's real. And they like that it's important, that it matters.” Citizenscience projects have made big discoveries. One found a previously unknown galaxy cluster (星系团). Another project helped assess how much damage a big earthquake had caused in Japan. And one of the first citizenscience projects helped scientists learn where butterflies go every winter.
Some adults worry about teens losing interest in science. That's one reason they hope that fun, exciting citizenscience projects can help them keep in touch, Long says. And she has some evidence that it's working, “Last year, we did have a couple of students say, ‘I really think I want to be a scientist now.’”
语篇解读：本文是一篇说明文。文章主要介绍了公民科学项目，使青少年体验实验的乐趣，激励着少年，为他们在科学的道路上指引着方向。
1．What is the purpose of Paragraph 2?
A．To support trials can make teens interested in science.
B．To prove failure is the mother of success in science.
C．To state Buckley has a talent for science.
D．To praise Buckley for her strong will.
解析：选A 推理判断题。第一段提到小时候，乔安娜·巴克利对科学并不感兴趣，直到她有机会尝试一下。这件事发生在她圣诞节得到一套化学仪器的时候。由此可知，第二段是为了支持第一段提出的观点，只有做了试验才能对科学感兴趣。故选A。
2．Why is citizen science more fun?
A．It carries out experiments frequently.
B．It must carry out experiments in groups.
C．It needs to seek for new solutions.
D．It demands to handle complex problems.
解析：选C 细节理解题。根据第四段第二句可知，它更有趣是因为需要寻找新的解决办法。故选C。
3．What can we know from what Prunuske said?
A．She participated in the experiment.
B．She took pride in what students took up.
C．Citizen science is popular with students.
D．Scientists are willing to employ students.
解析：选C 推理判断题。根据第五段第一句“Compared with ...purpose” 与一次性的实验相比，公民科学的最酷之处在于，学生们意识到这是有目的的。由此可知，公民科学受学生欢迎。故选C。
4．What is Long's attitude towards citizen science?
A．Concerned. B．Supportive.
C．Doubtful. D．Unclear.
解析：选B 推理判断题。根据最后一段可推断出，Long对于公民科学项目是支持的。故选B。
