The team said they also found additional reduction in activity in two regions of the prefrontal cortex (前額皮質(zhì)) linked to the sense of self, pared with when the actors were responding as themselves. Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments. Dr Steven Brown, from McMaster University in Canada, said, It looks like when you are acting, you are suppressing (壓制) yourself。故選C。根據(jù)第三段中的The new material was lighter and... more likely to survive the Journey.可知A項(xiàng)和B項(xiàng)正確；以及After all, ... made the chalk powder easier to erase.可知C項(xiàng)正確；D項(xiàng)文章未提及。t draw the maps their teacher wanted on their tiny boards, so Pillans put several slates together to create a large board. ”在1800年，一名英格蘭校長James Pillans想讓他的學(xué)生們畫地圖，但是學(xué)生們在他們的迷你板上無法畫出地圖，因此校長讓學(xué)生把他們的迷你板拼湊在一起來制造一個(gè)大的板。故選D。Function of the blackboard.【答案】 （1）D（2）B（3）D（4）C 【解析】【分析】本文是一篇說明文，通過描述黑板發(fā)展歷程向讀者介紹了黑板最早的時(shí)候確實(shí)是黑色的，隨后慢慢發(fā)展變成了綠色。s the main idea of the text? A.They39。They39。To draw students39。D.C.B.t plaining either. After all, the new greenboards made the chalk powder easier to erase. Plus, the enamel left less of a glare and the color was nicer to look at. At that point, people started using the word chalkboard as a more accurate descriptor, but blackboard still stuck around.（1）What did the late 18thcentury students use in class? A.t draw the maps their teacher wanted on their tiny boards, so Pillans put several slates together to create a large board. Problem solved! From there, the idea spread quickly as teachers could finally show a concept to the whole class at one time. By 1815, the massive writing spaces were mon enough to earn their own name: blackboard.s up with the name? Originally, blackboards were really black. Before wallsized blackboards existed, late 18thcentury students used their own mini boards made of slate (石板) or painted wood, according to Concordia University, Those first boards were, in fact, black, and they paved the way for the larger ones.根據(jù)全文的描述，可知作者對于東京奧運(yùn)倡議是持積極的態(tài)度，故選A。s a good start in showing what the public can do if they39。re in the homestretch for silver and gold medals, meaning the collection process can pack up at the end of March. 銅牌所需要的數(shù)量已經(jīng)達(dá)到了，并且到了最后關(guān)頭，也就是說，收集過程可以在3月底完成。 （1）考查推理判斷。B.PositiveIt saves the expense spent in making all the medals.D.D.final stageOnly producers of electronics participated in the project.D.s a good start in showing what the public can do if they39。s success. ll not only be wearing something that celebrates their sporting performance, but something that symbolizes lastingness. For both the 2020 Olympics and Paralympics, organizers aim to make all of the gold, silver, and bronze medals out of used electronics. This strong message about how to make use of ewaste has gotten a lot of Japan involved.re in the homestretch for silver and gold medals, meaning the collection process can pack up at the end of March.s largest mobile phone operator allowed the public to turn in phones at their shops, which counted a lot in the project39。 After being taken apart and sorted, the small electronics underwent a smelting process to extract (提煉) all the gold, silver, and bronze elements. Thanks to this initiative, the worldwide struggle with ewaste will have a global platform. According to a study published by the United Nations University— million metric tons of ewaste were made in 2016. Only 20% of that was actually recycled. Unfortunately, this figure is set to rise significantly in the ing years, moving to million metric tons by 2021. So while the Tokyo Olympics initiative might be just a drop in the bucket, it39。It is easy to get elements needed from the used electronics.C.collection effortC.It shows the power of advanced technology in daily life.C.s attitude to the Tokyo Olympics initiative?

So what39。 In 1800 when a Scottish headmaster named James Pillans wanted his students to draw maps, the students couldn39。 The color change came in the 1960s when panies sold, steel plates, coated with green enamel (漆) instead of the traditional dark slate. The new material was lighter and less fragile than the first blackboards, so they were cheaper to ship and more likely to survive the journey.

A.re more convenient to transport.C.re more useful than the traditional ones.（4）What39。Color of the blackboard.D.根據(jù)第一段中的，...late 18thcentury students used their own mini boards made of slate (石板) or painted wood...可知，18世紀(jì)的學(xué)生用的是“迷你板”。In 1800 when a Scottish headmaster named James Pillans wanted his students to draw maps, the students couldn39。 （3）考查細(xì)節(jié)理解。文章第一段前四句話點(diǎn)明了文章中心：我們看到的黑板大多是綠色的，為什么叫黑板？通讀全文也可知文章主要講述了黑板發(fā)展過程中顏色從黑色變成綠色的過程和原因。 Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love? However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than pretending to be someone — it involves embodying (體現(xiàn)) the text and language.（1）How did Dr Brown39。By
