【正文】 n cultures that have discovered farming, these consonants (輔音) are much more mon. The argument goes that farmers eat more cooked food and more dairy than hunter gatherers. Either way, they need to chew mush less, and to bite less with their front teeth. So farmers grew up with smaller lower jaws and more of an overbite than their ancestors who had to bite through harder foods. It became easier for them to make the labiodental consonants instead of purely labial (唇音) ones: one example is that f e to take the place of p. Romans said pater but English speakers (unless they39。d rather think of language as product of our thought Babies have an astonishing talent that adults entirely lose. By the age of one, they can recognise the significant noises around them and group them into a language. When we have lost this capacity as adults, it bees enormously difficult to distinguish between sounds that are glaringly different to a native speaker. It all sounds Greek to us. This is because the range of possible sounds that humans use to convey meaning may be as high as 2,000, but few languages use more than 100 and even then the significant noises－the phonemes (音素) of a language－each cover a range of sounds and so vague distinctions which would change the meaning of a word in other languages. 【點評】本題考點涉及詞義猜測和推理判斷兩個題型的考查，是一篇科研類閱讀，考生需要根據(jù)上下文的邏輯關系，進行分析，推理，從而選出正確答案。 （4）考查推理判斷。re made more aware of the issue. 所以盡管東京奧運會的提議只是杯水車薪，這是一個很好的開始，展示了如果公眾對這個問題有了更多的認識，他們能做些什么。根據(jù)最后一段中的 So while the Tokyo Olympics initiative might be just a drop in the bucket, it39。 in the homestretch 固定短語，“最后關頭”，故選C。根據(jù)第二段中的Already, the quantity needed for bronze medals has been met, and they39。根據(jù)第三段中的 In a period of about 18 months, a little over 5 million smartphones were collected thanks to cooperation with NTT DOCOMO. 在大約18個月的時間里，由于與NTT Doo的合作，收集了500多萬部智能手機，故選D。Indifferent【答案】 （1）D（2）C（3）D（4）A 【解析】【分析】本文是一篇說明文，介紹了日本將回收利用廢棄的電子產(chǎn)品中的金屬，用于制作2020年奧運會獎牌。C.Negatives attitude to the Tokyo Olympics initiative?

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.

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. 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科教類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據(jù)上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。根據(jù)第四段中的“The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it.”及全文內容可知，文章主要敘述了隨著越來越多的機器人具有人性化，參與者就可能越不會犧牲機器人。故選B。 （3）考查推理判斷。根據(jù)第三段中的“According to Sari Nijssen, the study set out to answer the following question:‘ Under what circumstances would adults be willing to sacrifice robots to save human lives?’可知，在這項研究中，參與者可能必須決定何時犧牲機器人。故選B。 （1）考查細節(jié)理解。Robot Saved, People Take the HitD.Robots, A Must for FutureB.Certain moral status should be attached to robots.D.Humanized robots offer less help to people.B.what robots should be like（3）What can be inferred from Paulus39。where to experience risksC.How to find more applications.（2）In the study the participants probably have to decide ________. A.How to treat them in life.C. This result indicates that our study group attached a certain moral status to the robot, says Paulus. One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could e into conflict with their intended function—to be of help to us.（1）What has bee a concern about robots? A. According to Sari Nijssen, the study set out to answer the following question: Under what circumstances would adults be willing to sacrifice robots to save human lives? The participants were faced with a hypothetical (假設的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine. Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards t
