Anonymizing job applications to eliminate（消除）discrimination is not easy.
“If you’ve got the grades, the skills and the determination, this government will ensure you can succeed,” declared the British prime minister, on October 26th, as he introduced plans to tackle discrimination in the workplace. Ten big employers in the public and private sectors—including the civil service, HSBC and Deloitte—have agreed to start recruiting（招募）on a “name-blind” basis in Britain; others may also follow suit. In such schemes, those drawing up shortlists of applicants cannot see their names, with the aim of reducing racial and sexual bias. But do they work?
Several countries have experimented with name-blind applications. In 2010 Germany’s Anti-Discrimination Agency, an advisory body, sponsored a voluntary scheme to get businesses to try it. In France a law passed in 2006 made the anonymizing of applicants’ CVs compulsory for firms of over 50 employees. But the government was slow in laying down the conditions for how the law would operate, and only started performing it last year.
In Sweden and the Netherlands there have been some trials. Discrimination against job applicants based on their names is well documented, particularly among ethnic minorities. An experiment in Germany found that candidates with German-sounding names were 14% more likely to be called for an interview than candidates with Turkish ones. A review of various studies, by the Institute for Study of Labour (IZA), a German outfit, found that anonymized job applications boost the chances of ethnic minority candidates being invited to an interview. A Sweden study found that it led to more ethnic-minority people being hired.
However, the results from other trials are less clear. A second Swedish experiment found that only women, not immigrants, were boosted by anonymous recruitment. According to the IZA, experiments in the
Netherlands showed no increase in the likelihood of ethnic-minority candidates being offered a job if their CVs were seen anonymously, suggesting that discrimination had slid in at the interview stage. Ensuring that a candidate is completely anonymous is also tricky.
A 2012 French study found that foreign-born candidates and those from poor districts were less likely to be called for interview when applications were anonymized. Its authors suggested that recruiters may have used other indicators, such as knowledge of Arabic, to identify race. In places suffering from religious tension, such as Northern Ireland, the name o f a school can reveal a candidate’s faith, while a few years missing on a CV may suggest maternity leave（产假）, and thus that the candidate is female. Going name-blind when shortlisting candidates may be a sensible start, but it is likely to be just a small step towards ending hiring bias.
58. What can learn from the passage?
A. In France, the government started the anonymized recruitment in 2006.
B. In Germany, chances of ethnic-minority name-blind candidates being interviewed are slighter.
C. In the Netherlands, the anonymous recruitment is more of a trick than an effective practice.
D. In Sweden, not only women but also immigrants may well enjoy a higher recruitment rate.
59. What does the underlined phrase “drawing up” in paragraph 2 mean?
A. writing out
B. taking in
C. making up
D. picking out
60. By writing the passage, the author tries to ______.
A. inform readers of the idea of anonymizing job applications
B. explain how anonymization in recruitment is operated
C. discuss whether anonymization in job applications works
D. promote the strategies of name-blind recruitment

SAN FRANCISCO---When you pull the headset over your eyes and the game begins, you are transported to a tiny room with white walls. Your task is to break out of the room, but you cannot use your hands. There is no joystick or game pad. You must use your thoughts.
You turn toward a ball on the floor, and your brain sends a command to pick it up. With another thought, you send the ball crashing into a mirror, breaking the glass and revealing a few numbers on a wall. You mentally type those numbers into a large keypad by the door. And you are out.
Designed by Neurable, a small startup founded by Ramses Alcaide, an electrical engineer and neuroscientist (神经科学家), the game offers what you might call a computer mouse for the mind, a way of selecting items in a virtual world with your thoughts.
Combining a headset with virtual reality goggles and sensors that can read your brain waves, this prototype (样机) is a few years from the market. And it is limited in what it can do. You cannot select an object with your mind unless you first look in its direction, narrowing the number of items you may be considering.
But it works. I recently played the game, which has the working title Awakening, when Alcaide and two Neurable employees passed through San Francisco, and a few hundred others tried it this month at the Siggraph computer graphics conference in Los Angeles.
The prototype is among the earliest fruits of a widespread effort to embrace technology that was once science fiction---and in some ways still is. Driven by recent investments from the US government and by the herd mentality (从众心理) in the tech world, a number of startups and bigger companies like
Facebook are working on ways to mentally control machines. They are also looking for smoother ways to use virtual reality technology. The increased interest in neurotechnology is partly a result of an effort the government administration started in 2013. The initiative helped create significant government financing for brain-interface companies and related work in academy.
The Neurable prototype shows what is possible today. Using electroencephalography, or EEG---a means of measuring electrical brain activity that has been around for a decade---the company can provide simple ways of mentally interacting with a game. Some companies hope to go much further and want to build ways of performing nearly any computing task with the mind. Imagine a brain interface for rapidly typing on a smartphone.
At Neurable, which is based in Boston, Alcaide and the member of his team are pushing the limits of EEG headsets. Although sensors can read electrical brain activity from outside the skull, it is very difficult to separate the signal from the noise. Using computer algorithms (算法) based on research that Alcaide originally published as a doctoral student at the University of Michigan, Neurable works to read activity with a speed and accuracy that is not usually possible. The algorithms learn from your behavior. Before playing the game, you train them to recognize when you are focusing your attention on an object. A pulse of light bounces around the virtual room, and each time it hits a small colored ball in front of you, you think about the ball. At that moment, when you focus on the light and it stimulates your brain, the system reads the electrical spikes of your brain activity. “Once we understand them, we can use them.” Alcaide expects.
61. Which of the following is TRUE about the design of the game?
A. You can break the glass with a simple click of the mouse.
B. You can select as many items around you as you like.
C. The game has boosted the government revenues since its release.
D. The game can’t work without sensors and virtual reality technology.
62. What can be inferred from the underlined sentence in Paragraph 6?
A. What was a fantasy is coming true with technology.
B. Whatever efforts you make might not fruit success.
C. Science fiction leads to the development of the prototype.
D. The technology behind the prototype enjoys wide popularity.
63. What can we learn from the last paragraph?
A. It’s not uncommon that we usually have different voices in mind.
B. There’s still a long way to go before the game is fully mat ured.
C. The Alcaide team focuses on limiting the usage of headsets.
D. It’s impossible for Alcaide to read activities fast and accurately.
64. What might be the best title of the passage?
A. A game controlled with mind
B. A machine leading to the future
C. Neurable: king of tomorrow
D. Neurology: a cutting-edge zone
D
Miss Martha, aged 40, kept a little bakery on the corner.
Two or three times a week a customer came in in whom she began to take an interest. He spoke English with a strong German accent. His clothes were worn and darned in places, and wrinkled and baggy in others. But he looked neat, and had very good manners.
1.He always bought two loaves of stale bread. Fresh bread was five cents a loaf. Stale ones were two for five. Never did he call for anything but stale bread.
Once Miss Martha saw a red and brown stain on his fingers. She was sure then that he was an artist and very poor. No doubt he lived in a attic painting pictures and ate stale bread.
Often when Miss Martha sat down to her chops and light rolls and jam and tea she would sigh, and wish that the gentle-mannered artist might share her tasty meal instead of eating his dry bread.
In order to test her theory as to his occupation, she brought from her room one day a painting that she had bought at a sale, and set it against the shelves behind the bread counter.
Two days afterward the customer came in.
"Two loafs of stale bread, if you please.
"A fine picture, madam," he said while she was wrapping up the bread.
"Yes?" says Miss Martha "I do admire art.You think it is a good picture?"
"Der balance," said the customer, is not in good drawing. Then he took his bread, and hurried out.
How and kindly his eyes shone behind his spectacles! To be able to judge perspective at a glance -- and to live on stale bread! But genius often has to struggle before it is recognized. She thought he began to look thinner. 2. Her heart ached to add something good to eat to his meagre purchase, but her courage failed at the act. She did not dare affront him. She knew the pride of artists.
Miss Martha took to wearing her blue-dotted silk waist behind the counter. In the back room she cooked a mysterious compound of quince seeds and borax.
One day the customer came in as usual, and called for his stale loaves. 3. While Miss Martha was reaching for them, a fire-engine came lumbering past. He hurried to the door to look, as any one will. Suddenly inspired, Miss Martha seized the opportunity. With a bread knife Miss Martha made a deep slash in each of the stale loaves, inserted a generous quantity of butter, and pressed the loaves tight again.
When the customer turned once more she was tying the paper around them.
When he had gone, after an unusually pleasant little chat, Miss Martha smiled to herself. For a long time that day her mind dwelt on the subject. She imagined the scene when he should discover her little deception.
He would prepare for his luncheon of dry bread and water. He would slice into a loaf -- ah!
Miss Martha blushed. Would he think of the hand that placed it there as he ate? Would he?
The front door bell jangled viciously. Somebody was coming in, making a great deal of noise.
Martha hurried to the front. Two men were there. One was a young man smoking a pipe -- a man she had never seen before. 4. The other was her artist.
His face was very red, his hat was on the back of his head, his hair was wildly rumpled. He clinched his two fists and shook them ferociously at Miss Martha. At Miss Martha.
"Dummkopf!" he shouted with extreme loudness; and then "Tausendonfer!" or something like it in German.
Miss Martha leaned weakly against the shelves and laid one hand on her blue-dotted silk waist. The young man took the other by the collar.
"Come on," he said, "you've said enough." He dragged the angry one out at the door to the sidewalk, and then came back.
"Guess you ought to be told, ma'am," he said, "what the row is about. That's Blumberger. He's an architectural draftsman. I work in the same office with him.

同学们，大家好！ 这份考前辅导材料先从一则故事入手，让我们先来走进它： 1968年，在墨西哥奥运会的百米赛道上，美国选手吉?海因斯撞线后，转过身子看运动场上 的记分牌。当指示灯打出9.95秒的字样后，海因斯摊开双手自言自语地说了一句话。这一 情景通过电视网络，全世界至少有好几亿人看到，可是由于当时他身边没有话筒，因此海因 斯到底说了句什么话，谁都不知道。但人们清楚地知道这是人类历史上首次有人在百米赛道 上突破10秒大关。 1984年，洛杉矶奥运会前夕，一位叫戴维?帕尔的记者在办公室回放墨西哥奥运会的资 料片，当再次看到海因斯回头、摊手、自言自语的镜头时，他想他一定说了一句不同凡响的 话。但这一新闻点，竟被当时400多名在现场的记者给漏掉了，这实在是个天大的遗憾。于 是他决定去采访海因斯，问他当时到底咕哝了句什么话。当被问起16年前的事时，海因斯想了想笑着说：“当时难道没人听见吗？我说，上帝啊，那扇门原来是虚掩着的！” 谜底揭开之后，戴维?帕尔接着对海因斯进行了采访。针对那句话，海因斯说：“自美国运动员欧文斯于1936年5月25日在柏林奥运会上创下10.03秒的百米赛世界纪录之后，以詹姆斯?格拉森医生为代表团的医学界断言，人类的肌肉纤维所承载的运动极限不会超过 每秒10米，的确，这一纪录保持了32年，这一说法在田径场上非常流行，我也以为这是真的，但是，我想我的最高水平该跑出10.01秒的成绩。于是，每天我以自己最快的速度跑50公里。因为我知道，百米冠军不是在百米赛道上练出来的。当我在墨西哥奥运会上看到自己 9.95秒的纪录之后，我惊呆了，原来10秒这个门不是紧锁着的，它虚掩着，就像终点那根 横着的绳子。” “百米冠军不是在百米赛道上练出来的。”，“每天我以自己最快的速度跑50公里。”同学们，就是这每天的坚持成就了海因斯在最后的赛道上突破了自己的“10秒大关”，推开了虚掩着的成功之门，成就了自己，创造了历史。 高考不也如此？看似枯燥、单调、甚至令人心烦的一份一份小练、一题一题讲解、一遍 一遍重复，回想起来不正是铺就了我们通向虚掩着的那扇门吗？ 越是接近终点，越要屏气凝神、步履坚定、成竹在胸。因为我们知道，翻过了这份“考 前辅导材料”，“2018年高考卷”的尊容就在那扇虚掩着的门背后。 去吧，去轻轻地推开它！ 高三英语组全体老师预祝莘莘学子梦想成真！ 2018届高考英语考前辅导 应试总方法：“一看二序三速四查”。 一看：充分利用考前５分钟，认真阅卷，同时调节紧张的心理。阅卷时要注意，答题要求、 题量、总页码及正反面的试题。不要迫不急待答题。“磨刀不误砍柴工”。 二序：遵循先易后难的原则，不要违反规律。 三速：在规定的120分钟内完成全部试题需要一定的速度。以下为各项题目建议时间分配：（学生可根据自己的实际作适当调整） 听力单项、完形阅读理解任务型书面表达涂卡、整理 20分钟25分钟35分钟13分钟25分钟2分钟（建议做好一大题 就涂好一大题） 四查：在完成全部试题后要认真检查： 1. 试题是否全部完成（包括正、反面）。不要轻易改答案（尤其是阅读理解），除非恍然大悟。 2. 答题卡是否全部涂规范、正确，考号、姓名、科目等是否正确无误。 3. 对漏做、疑难的题目进行强攻。

It includes airfare ($225), hotel ($170), dining out ($116) and dressing up ($95) and the gift. If you have weddings to attend this year, here are some tips for you to avoid breaking the bank. 1. Book flights in advance The moment you decide to attend a wedding is the time to check flight prices at the best time. Plane fares are higher in the summer, especially in July and August. Booking in advance will save you money, as will watch for sales on lower-cost carriers like JetBlue and Frontier. You can check Google Flights for a calendar of prices showing the cheapest days to fly from apps like Hopper to get real-time alerts when a fare is at its lowest price point. 2. Don't blow your budget on the gift If you've got the money, an expensive gift is lovely. But there's no need to take out loans to prove your love for the happy couple. Skip an expensive necklace by giving (an appropriate amount of) cash instead. To save on the gift, consider making one: A photo album or scrapbook of memories with the bride and groom shows how much you care. You could also share the gift with other guest(s) or even make gifts with DIY ideas by yourself to save money. 3. Use old dresses and suits You don't always have to be on a new dress for a wedding. While men have the option of repeating their suits, women are more likely to spend money on new clothes for the special occasion. But before you take out your wallet, consider reinventing something already in your
2018年江苏高考英语试题答案解析 21.By boat is the only way to get here,which is_______we arrived. A.where B.when C.why D.how 【答案】D 【解析】考查名词性从句。句意：乘船是到达这里唯一的途径，这就是我们如何到达的。分析which引导的非限定性定语从句可知，后面为表语从句。分析句意可知，这里用连接副词how引导表语从句，充当方式状语，表示“如何”。故选D。 拓展：本题考查表语。首先需要弄清句意及分析句子结构，然后根据前句By boat is the only way to get here提示可知作方式状语，就不难选出正确答案。 22.Kids shouldn’t have access to violent films because they might_______the things they see. A.indicate B.investigate C.imitate D.innovate 【答案】C 【解析】考查动词词义辨析及语境理解。句意：孩子不应该接触暴力电影，因为他们也许会模仿他们所见的事情。A.indicate指示；B.investigate调查；C.imitate模仿；D.innovate改革。故选C。 拓展：本题考查动词辨析。动词和动词短语的考查是高考重点考查的知识点，解题时要区分清选择项的含义与区别，再联系句意进行判断，从而选出正确答案。考生在平时学习过程中要注重动词和动词短语的识记与掌握。 23.Self-driving is an area_______China and the rest of the world are on the same starting line. A.that B.where C.which D.when 【答案】B 【解析】考查定语从句。句意：自动驾驶是一个中国和世界其它国家都在同一起跑线的领域。句中先行词为area，在从句中作地点状语，故用关系副词where，相当于in which。故选B。拓展：本题考查定语从句。定语从句是高考重点考查知识之一，分析定语从句需抓住两点：1.找准先行词。2.看先行词在从句中所作的成分。抓住这两点，再根据句意，从而能够判断出正确的关系词。

Any type of hobby that you can think of can be found in Australia. The following are four top Australian pastimes. Fishing Fishing is probably one of the most popular free-time activities in Australia and many people love spending their free time waiting at the end of a rod for a fish to bite on their line. There is free public access to almost all beaches，canals and coasts，which means there are plenty of great places to fish. Surfing Another popular pastime of the Australians is surfing. Australia has a lot of beautiful surf spots，especially in Queensland. Queensland has some of the best surf beaches in the country such as Noosa Heads，Stradbroke Island，and Burleigh Heads，with the Gold Coast being the best known.
