【正文】 ysical constants (物理常數(shù)).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20th 2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.（1）What does Paragraph 1 mainly tell us? went before libra in measurement. things used to be adopted as measures. were accepted as measures by the Romans. measurement systems were gradually formed.（2）How does the author develop the second paragraph? time order. analysis. space order. parison.（3）Which of the following countries used SI as an official measurement? ....（4）What will the world39。s measurement bodies achieve at the meeting held in Versailles? will e up with seven new SI units. will set May 20th as a new international festival. will redefine four SI units including the kilogram. will decide on a new measure used in the laboratory.【答案】 （1）B（2）D（3）A（4）C 【解析】【分析】本文是一篇說明文，法國凡爾賽宮舉辦的國際計(jì)量大會(huì)，將對(duì)目前使用的國際單位制中的四個(gè)基本單位進(jìn)行重新定義，其中包括對(duì)千克的重新定義。 （1）考查推理判斷。根據(jù)第一段中的“man has been the measure of many, if not all, things ”以及下文提到的用作計(jì)量單位的手、腳、谷物重量和參考角豆種子重量的磅可知，本段主要講述了不同的東西被用作計(jì)量單位。故選B。 （2）考查推理判斷。根據(jù)第二段中的“The king39。s foot ...around a centimetre shorter than the Belgic foot”和“Greek, Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos,以及The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south”可推知，本段作者主要運(yùn)用了對(duì)比的寫作方法，把同一計(jì)量單位在不同國家之間或者在同一國家不同區(qū)域間的差異進(jìn)行了說明。故選D。 （3）考查細(xì)節(jié)理解。根據(jù)第三段中的“it was the French who in 1799 made it law和The Syst232。me International d39。Unit233。s (SI, or the metric system, as it is better known)developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States ”可知，在所給出的四個(gè)國家中，只有法國采用國際單位制(SI)。國際單位制是現(xiàn)時(shí)世界上最普遍采用的標(biāo)準(zhǔn)度量衡單位系統(tǒng)，采用十進(jìn)制進(jìn)位系統(tǒng)。故選A。 （4）考查細(xì)節(jié)理解。根據(jù)最后一段中的“At a meeting in Versailles, France, on November 16th, 2018, the world39。s measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units...will follow the other three...in being redefined in terms of the values of physical constants”可知，在法國凡爾賽宮召開的會(huì)議上，七個(gè)基本計(jì)量單位中的四個(gè)將被重新定義，其中包括對(duì)千克的重新定義。故選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。3．犇犇閱讀理解 News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world39。s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession. Unlike previous news robots though, Xin does not read news like a cold machine。 she reads it almost like a human being. The muscles on her face stretch and relaxand her reactions changeas she continues reading. That39。s why many news anchors were worried: Will AI replace us in the near future? To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro electric motors behind her face move to make her expressions seem more human. Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person39。s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs Both the technologies used to make Xin39。s performance impressive are mature. The real difficulty lies in the third the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don39。t always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.（1）What does the underlined word reluctant in the first paragraph mean? A.Delighted.B.Unwilling.C.Confused.D.Optimistic.（2）What can we infer about previous news robots? A.They read news without expressions.B.They looked like a human beingC.They could interview sports starsD.They could interact with audience.（3）What do we know about the third technology? A.This technology is very perfect so farB.This technology is quite popular nowC.This technology remains at the theoretical stageD.This technology is far from mature.（4）From the last paragraph, we can draw a conclusion that____. A.human news anchors should learn from AT anchors to save their jobsB.Al anchors perform much better than human news anchors at presentC.Al news anchors won39。t replace human news anchors in the near futureD.Xin Xiaomeng s expressions vary so naturally that they are true to life【答案】 （1）B（2）A（3）D（4）C 【解析】【分析】本文是一篇說明文，上周日，新華社新聞主播辛?xí)悦瘸蔀槭澜缟系谝晃慌匀斯ぶ悄苄侣勚鞑?，作者介紹了人工智能背后的技術(shù)，并指出在不久的將來，人工智能新聞主播不會(huì)取代人類新聞主播。 （1）考查詞義猜測。根據(jù)第一段中的Xin Xiaomeng began working as the world39。s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday及第二段中的That39。s why many news anchors were worried: Will AI replace us in the near future?可知，擔(dān)心將來自己的工作會(huì)被人工智能取代的新聞主播一定不愿意透露下面這個(gè)消息：上周日，新華社新聞主播辛?xí)悦瘸蔀槭澜缟系谝晃慌匀斯ぶ悄苄侣勚鞑?，由此可知畫線詞詞義為不愿意的，故選B。 （2）考查推理判斷。根據(jù)第二段中的Unlike previous news robots though, Xin does not
