A
Jeremy Baras remembers the first time he ever saw a pop-up restaurant. The 26-year-old entrepreneur
was on vacation in England four years ago and had to look up at the London Eye Ferries wheel to see it.
Hanging above him was a capsule（航天舱）full of diners who were served a new course each time a
revolution was made. “I t hought that was the coolest thing ever”, he says. Baras, who founded https://www.doczj.com/doc/327368160.html, in 2012 to promote the idea of pop-up restaurants in the USA, has been studying them
ever since.
Pop-ups, which have been around since at least the early 2000s, are open anywhere from a few hours
to several months, but their defining feature is that they are temporary. They may be only a tiny part of the
$709 billion U.S. restaurant industry, but pop-ups have gotten a boost in recent years as a lower-cost,
lower-risk way for entrepreneurs to test the waters. Some restaurant owners see them as a way to renew
interest in existing locations. And some struggling cities, like Oakland, California, have turned to them to
help revitalize local economies impacted by the recession（衰退）.
The concept has been especially popular with up-and-coming chefs who want to test-drive as a menu
concept without investing a fortune in a permanent space. “Your cooks and chefs are really talented, but
menu,”
s ays Zach
kitchen cooking somebody else’s
they’re stuck in the back of somebody else’s
Kupperman, chief businessman officer and co-founder of Dinner Lab.
Chefs in Dinner Lab cook in the middle of space, give a brief introduction about the menu and
themselves — and then bravely listen to diner feedback afterward. Pop-ups’ temporary nature also allows restaurateurs to charge a deposit to make sure the diners will show up.
Of course, trends in the food industry come and go quickly, and there is no guarantee that diners won
tire of the concept. Some entrepreneurs have resorted to even weirder locations — in a former limestone
mine, say, or at the top of a crane —to keep customers interested. “It’s not quite part of the mainstream says Baras.
economy yet.”
51. What does the underlined p art “a revolution was made” in Paragraph One possibly mean?
A. Chefs designed creative dishes.
B. Diners tasted food in a new and creative way.
C. The capsule containing diners made a circle.
D. Great changes were made in the food industry.
52. Perspective chefs are drawn to pop-ups due to the fact that ________.
A. pop-ups are becoming increasingly popular with diners worldwide
B. they have the desire to explore a safer way to make a living
C. their investment in pop-ups will bring them a long-lasting fortune
D. pop-ups provide a changeable test field for talented chefs’ creativity
53. The writer’s
purpose of writing the passenger is ________.
A. to appeal to people to dine out in pop-up restaurants
B. to give a brief introduction of pop-up restaurants
C. to warn business owners of the appearance of pop-up restaurants
D. to foresee the future of pop-up restaurants’ development
B
The pills we take to treat anxiety may affect the behavior of fish, new research in the journal Science
suggests.
Swedish researchers found a common drug in rivers downstream of wastewater treatment plants. It is a
drug for treating anxiety, called oxazepam. It is accumulating in fish and makes them bolder. Wastewater
treatment plants are not designed to get rid of drugs. As a result, the drugs end up in wildlife, reaching
harmful levels.
“It’s something we don’t think about very often, but there are a lot of similarities between fish and
is a biologist
humans. So some of our responses to drugs can be seen in fish as well,” said Karen Kidd. She
at the University of New Brunswick, Canada. The mood-altering drugs get into waterways when people
taking the prescriptions throw unused pills into the waste stream.
The researchers let perch（鲈鱼）swim in lab tanks with concentrations similar to those found
downstream from wastewater treatment plants. “The perch preferred to swim alone rather than in large
groups. They were more likely to explore their environment,” said Micael Jonsson of Ume? University in Sweden, who helped lead the research.
adventurous behavior required more energy. And they ate more plankton（浮游生Johsson said, “This
物）, or tiny algae-eating animals, to guarantee enough energy for their activities. This could reduce the
population of plankton.” The result could be more algae
（水藻）. On the other hand, the new behavior could
lead to the opposite effect. If perch make themselves closer to their natural enemies, they are likely to be
eaten by them.
None of the scientists is suggesting that people should give up these drugs. They just want to reduce
the effects of the medicines on the environment. They recommend wastewater treatment plants should be
redesigned to get rid of these medicines. But Kidd said that would be too expensive for some communities.
Bryan Brooks, director of the Environmental Health Science Program at Baylor University, said drugs
could also be designed to break down more quickly in the environment. And the government could
continue to run recycling programs where people drop off their unused drugs at government locations.
Brooks said he’s particularly concerned about drug effects on aquatic（水生的）environments, like the
Trinity River south of Dallas and the South Platte River near Denver, where the majority of the flow comes
from treated wastewater. In the developing world, he said, the problem may be even worse, because of
careless wastewater treatment and industrial regulations.
54. Which of the following best describes oxazepam’s effect on fish?
A. It causes fish to be more daring.
B. It makes fish much stronger.
C. It has little influence on fish.
D. It helps treat a fish disease.
55. What will happen if perch become adventurous?
A. They will eat more algae.
B. There will be less plankton.
C. They will need more oxazepam.
D. Their natural enemies will be stronger.
56. What would be the best title for the passage?
A. More wastewater treatment plants are needed
B. Fish in wastewater become more adventurous
C. Drugs for treating mental diseases end up in wildlife
D. Anxiety drugs found in rivers change the behavior of fish
C
Culture can affect not just language and customs, but also how people
experience the world on surprisingly basic levels.
Researchers, with the help of brain scans, have uncovered shocking
differences in perception（感知）between Westerners and Asians, what they see
when they look at a city street, for example, or even how they perceive a simple
line in a square, according to findings published in a leading science journal.
In western countries, culture makes people think of themselves as highly independent individuals.
When looking at scenes, Westerners tend to focus more on central objects than on their surroundings. East
Asian cultures, however, emphasize inter-dependence. When Easterners look at a scene, they tend to focus
on surroundings as well as the object.
Using an experiment involving two tasks, Dr Hedden asked subjects to look at a line simply to estimate its length, a task that is played to American strengths. In another, they estimated the line
relative to the size of a square, an easier task for the Asians.
The level of brain activity, by tracking blood flow, was then measured by Brain Scanners. The experiment found that although there was no difference in performance, and the tasks were very easy, the
levels of activity in the subjects’ brains were different. For the Americans, areas linked to attention lit up more, when they worked on the task they tended to find more difficult —estimating the line’s size relative to the square. For the Asians, the attention areas lit up more during the harder task also — estimating the
line’s length without comparing it to the square. The findings are a reflection of more than ten years of previous experimental research into East-West differences.
In one study, for instance, researchers offered people a choice among five pens; four red and one green. Easterners were more likely to choose a red pen while Westerners were more likely to choose the green

苏州市2017届高三调研测试英语试卷解读与分析 苏州市教科院刘洪等 苏州市2017届高三调研测试英语试卷的设计是以2015年和2016年江苏省高考试卷为指导思想和命题方向，比较真实地考查高三学生本学期的学习成果和学生的综合英语运用能力。从基础到能力题的选材上尽量体现核心素养内涵，充分展示立德树人和积极向上的正能量引导，同时根据英语课程标准和江苏省高考说明，体现人文关怀和科学情怀。试题的设计没有偏题、怪题，但考虑到为下学期英语学习提出警示和鼓励学生更加努力学习，不盲目乐观，以便能够从容面对2017年高考，因此试卷难度系数定位在略高于2015与2016年江苏省高考题，试卷总词数也大于这两年高考（本卷：4980；2016：4461；2015：4395）。现将试卷各题型作详细解读和分析。 一、听力 听力选材突出时代性和日常性，所设计的情景基本是日常生活常见情景，语言突出原汁原味，并略有一些涉及英美文化和日常语言要素。 1—5题没有拐弯抹角。第1题，刻意加了一点幽默，目的让学生会心一笑，放松心情。第4题谈观看“美国队长”的感受，需要简单推理。第5题有一定难度，需要注意说话者的语气，同时，用阿甘正传的名言来检验学生的知识面，但即使不知道也可以从最后一句判断出正确选项。 按照近八年高考听力第二节每段材料一贯的设题题数，第6、7两段对话各设2道题，第8段对话设3道题，第9、10两段材料各设4道题。第6段对话涉及国外风俗习惯，题目难度不大。第7段对话是家人出游的感受，有人物的关系和事实判断题，直截了当，比较容易。第8段对话是有关邀请的日常交际情景，有简单推算和结果判断，难度中等。第9段对话是朋友在某处相逢并邀请做客的对话，对话相应较长，但信息比较直接，考题的设计有细节题，例如：从picking up some soap要推断出会话的地点，语句较短，容易忽略，有一定难度，其他难度中等。第10段独白有关健康常识，词汇量略大，但题目设计与材料紧密相关，没有深层推断题，但由于有些单词在口语不是很常用，会造成理解有一定困难，也是整套听力最易拉分的一段。 总体来讲，听力试题比较难的题是5、13、19、20，其他均与2016年相仿。 二、单项选择 单项选择的来源主要是第9、10模块、VOA慢速英语、China Daily、https://www.doczj.com/doc/327368160.html,、CBS news及英语名人名言等。这次考试充分体现与教材的正相关，除了语言点突出了第9、10模块的各类从句和连接词外，一些语言点和词汇的考查也都以教材为主要资源，这一点与近两年高考相似，源于教材而又有别于教材。从题量来看，第21、22、23、24、25、28、29、32、33、34、35等11题都与教材有关，有的是课文的原句或者原句的改编。这样出卷的意图是，让学生能体会到这个学期学习的内容在考试中有所体现，让学生有一定的成就感和学而致用的体验，为今后的课堂上认真学习起到积极推动作用，也改变诸多任课教师所认为的教材与测试毫无联系的错误观念。单项选择总体设计紧随2015与2016高考题，难度紧扣高考，突出“运用语言和词汇的基本知识在真实情景中解决问题”导向，没有故意设计让学生出错的陷阱题，同时也突出语言的“积极阳光的心情”表达，从而起到激励学生奋发向上的积极人生观。然而，由于学生的语言知识一直是学生英语水平和能力提升的瓶颈，有可能该题型的均分不会乐观。但是，如果因为得分不理想，教师就用大量的时间和精力去让学生训练语言知识题，就本末倒置了。因为该题型中很多题目还是考查学生的语言理解能力，而非过多地语法知识，即使存在的一些也具有一定的情景性，且难度也不是太大。因此，当时间

At Google in Silicon Valley, the princess is the one defending the castle. Parisa Tabriz is a 31- year-old with perhaps the most unique job title in engineering- “Google Security Princess ”. Her job is to hack into the most popular web browser （浏览器）on the planet, trying to find weaknesses in the system before the “black hats ” do. To defeat Google's attackers, Tabriz must firstly think like them.Tabriz's role has evolved dramatically in the eight years since she first started working at Google. Back then, the young graduate from Illinois University was one of 50 security engineers---today there are over 500. Cybercrime （网络犯罪）has come a long way in the past decade - from the Nigerian Prince Scam to credit card theft. Tabriz's biggest concern now is the people who find bugs in Google's software, and sell the information to governments or criminals. To fight against this, the company has set up a Vulnerability Rewards Program, paying anywhere from $100 to $ 20, 000 for reported mistakes. It's a world away from Tabriz's computer-free childhood home in Chicago. The daughter of an Iranian-American doctor father, and Polish-American nurse mother, Tabriz had little contact with computers until she started studying engineering at college. Gaze across a line-up of Google security staff today and you'll find women like Tabriz are few and far between （稀少的）--- though in the last few years she has hired 班级姓名准考证号考场号座位号
