2020-2021學(xué)年新教材英語外研版必修第三冊課時(shí)作業(yè)：Unit 3　The world of science 第二課時(shí)　Using language Word版含解析

1、好好學(xué)習(xí)，天天向上課時(shí)作業(yè)8using languageawhen a mathematics student was examined in the hospital, dr john lorber discovered that he had almost no brain at all.normally, the condition is quite severe in the first months of babyhood。even when someone survives， he or she is usually seriously disabled。somehow， thou

2、gh, the student had lived a perfectly normal life and went on to gain a degree in mathematics。this case is by no means as rare as it seems。lorber has identified (確認(rèn)） several hundred people who have very small brains but who appear to be normally intelligent people。he describes some of them as having

3、 “no detectable brain”， yet they have scored up to 120 in iq tests。no one knows how people with “no detectable brain” are able to function at all, let alone graduate in mathematics。one suggestion is the old idea that we only use a small percentage of our brains anywayperhaps as little as 10 per cent

4、。but more recent research shows this idea is a misunderstanding dating from research in the 1930s in which the functions of large areas of the brain could not be determined and were named “silent, while in fact they are linked with important functions like speech and abstract thinking。the other inte

5、resting thing about lorbers findings is that they remind us of the secret of memory. at first it was thought that there is a part in the brain for memory, like the memory chips in a pc.but further research of the brain has turned up the surprising fact that memory does not depend on any particular a

6、rea in the brain.as one scientist put it, “memory is everywhere in the brain and nowhere.”but if the brain is not a place for classifying and storing experiences and analyzing them to enable us to live our lives, then what on earth is the brain for？and where is the seat of human intelligence? where

7、is the mind?本文是一篇科普類說明文。作者從一個(gè)“無腦人”案例入手，分析了人類大腦的功能問題。1what will usually happen to a very young baby without brain？ait will die。bit will survive。cit will be intelligent。dit will become disabled。答案:a解析:推理判斷題。根據(jù)第一段中的第二句和第三句可知，通常情況下，在出生的前幾個(gè)月里，這種情況(無腦）是非常嚴(yán)重的，有人即使存活下來，通常也會(huì)有嚴(yán)重的殘疾.由此可知，這種情況對嬰兒來說死亡率很高，故選a項(xiàng)。2w

8、hat is the new finding of the functions of the brain?amuch of the brain is useful。bthe brain is in fact of no use。cthe brain determines ones iq。donly a small part of the brain is used。答案:a解析：細(xì)節(jié)理解題。根據(jù)第三段中的第二句可知，舊的觀點(diǎn)是我們僅僅用了大腦很小的一部分,但下文對這一觀點(diǎn)進(jìn)行了否定.“but more recent research shows this idea is a misunders

9、tanding.。abstract thinking.”即這種舊觀點(diǎn)是一種誤解.由此可知，我們并非只使用大腦中很小的一部分，而是大腦的大部分區(qū)域都跟重要的功能相關(guān)聯(lián),都是有用的，故選a項(xiàng)。3what do we know about the existence of memory？awe use all of our brain.bwe have memory chips.cwe are fully aware of it.dwe are still confused about it。答案：d解析：推理判斷題.根據(jù)題干中的關(guān)鍵詞memory 定位到最后兩段。作者在指出關(guān)于人類記憶的兩種截然不

10、同的觀點(diǎn)之后,連續(xù)提出了三個(gè)疑問，因此可知我們對于記憶的存在依然是很困惑的,故選d項(xiàng).bfuturologists (未來學(xué)家） predict that life will probably be very different in 2050 in all the fields of activity， from entertainment to technology。first of all, it seems that tv channels will have disappeared by 2050。instead, people will choose a programme fro

15、nd and deaf people see again and hear again。scientists will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have.本文是一篇說明文。文章從娛樂、交通、機(jī)器人、醫(yī)藥學(xué)等角度對2050年時(shí)人類生活的變化進(jìn)行了展望。4what is not true about television by 2050 according to this passage?aone will

16、 be able to smell the food on television。bone can have a try of the food you see on television.cthere will be no channels for us to choose programmes。dtelevisions will be completely controlled by computers.答案：b解析:細(xì)節(jié)理解題.第一段最后一句提及未來人們可以看、聞、觸摸電視上的東西，但沒有提及可以品嘗。故b項(xiàng)表述與文章不符。5what can be the development of

18、 accidents，因此c項(xiàng)正確。6it can be implied in the passage that by 2050 _。apeople will live more healthily and longerbcomputer will control the speed of carscpeople can read newspapers through a computerdthere will be no people working in factories答案：a解析：推理判斷題。根據(jù)最后一段中的“medicine technology will have conquer

19、ed many diseases”判斷，未來人們會(huì)更健康、更長壽。7what is the authors attitude towards peoples life in future？adoubtful。bsad。chappy。dworried.答案:c解析：觀點(diǎn)態(tài)度題。作者在敘述未來生活各個(gè)領(lǐng)域的變化時(shí),給予了積極評價(jià)，如clean， in just two hours， prefer， conquer等詞匯的應(yīng)用，體現(xiàn)了作者積極樂觀的態(tài)度。因此選c。根據(jù)短文內(nèi)容,從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。it is sometimes possible to

21、 back together and it wont turn on, it is likely that some water has gotten down inside the phone. _3_. you can remove the battery and sim card from the phone once again and place all three components into a bowl filled with rice。 this may work because rice is very absorbent。_4_. if the rice method

22、either did not work, you can take the phone apart and lay all its pieces outside in direct sunlight for several hours。 the heat from the sun may completely dry out the inside and outside of the phone and its parts。 if it is raining or the sun is not out， you can use a blow dryer on low heat to get t

23、he same results。if all of your attempts at repairing your phone are unsuccessful, you will likely have no choice but to take it to your cell phone provider or to a place that repairs cell phones to get it fixed。 unless your phone is very valuable, the cost of repairing the phone might be higher than

25、g a new onefwhen this happens, you can still repair it using rice, thoughgplace them onto a paper towel so the water can completely drain本文屬于說明文，介紹了四種維修被水損壞了的手機(jī)的簡單易行的方法。1d解析：根據(jù)空后the longer you wait, the more likely the phone is unrepairable可知，d項(xiàng)提出盡快修理它可能更好，為下文“你等待的時(shí)間越長,手機(jī)就越有可能無法修復(fù)?！弊鲣亯|，故選d。2g解析：根據(jù)空前

26、additionally， you should take out the sim card and battery可知，g項(xiàng)提出“把它們放在紙巾上,這樣水就能完全排干”是前文動(dòng)作的目的，符合語境,故選g。3f解析:根據(jù)空前if you put your water。damaged cell phone back together and it wont turn on, it is likely that some water has gotten down inside the phone. 可知，如果你把被水損壞的手機(jī)組裝好,但它仍不能開機(jī)，很可能是手機(jī)內(nèi)部進(jìn)水了，再根據(jù)后句的rice可

27、知f項(xiàng)提出“但是,當(dāng)這種情況發(fā)生時(shí)，你仍然可以使用大米進(jìn)行修復(fù)。”符合語境，故選f。4b解析：本空是一個(gè)主題句。本段主要是介紹通過光照和使用吹風(fēng)機(jī)對被水損壞的手機(jī)進(jìn)行維修,所以b項(xiàng) “你也可以用熱來維修它”符合本段主旨,故選b.5e解析：根據(jù)空前unless your phone is very valuable, the cost of repairing the phone might be higher than what you paid for it。 可知，除非你的手機(jī)很值錢，否則修理手機(jī)的費(fèi)用可能會(huì)比你買手機(jī)花的錢還多，e項(xiàng)“那你最好買個(gè)新的”是前文的結(jié)果，符合語境，故選e。閱讀

28、下面材料，根據(jù)其內(nèi)容和所給段落開頭語續(xù)寫兩段，使之構(gòu)成一篇完整的短文。續(xù)寫的詞數(shù)應(yīng)為150左右。one time， the teachers at a school wanted to teach the students about airplanes. while all airplanes can fly, some are able to fly farther than others。 this is because not all airplanes are built the same。 for example, a fighter plane looks very differ

29、ent from a plane that people fly in when they want to go on a holiday. the teachers wondered how they could make students understand this。then， the science teacher, mr moose， decided that the school should have a paper airplane contest. every student would design a paper airplane。 they would stand i

30、n a line in the playground behind the school。 the students would take turns throwing their airplanes. the student whose airplane went the farthest would win.when mr moose announced the paper airplane contest to the students, they were very excited. a student named paul, who was on the school sports

31、team, said to everyone else that his airplane would win. “i am the strongest, paul said。 “so i will be able to throw my airplane the farthest.”however, while paul was saying this， another student， brian, was thinking how he could win。 brian did not play any sports and was not very strong. but he lov

32、ed airplanes and really wanted to win the contest.brian realized what he had to do。 he went to the store and bought a big stack （疊） of paper。 when he got home, he took the paper into his backyard. he took a piece of paper and folded an airplane。 it didnt go very far， so brian took another piece and

33、folded another airplane and threw it. this airplane went a little farther。 brian kept folding different kinds of airplanes and throwing them。 some went very far and some did not。 finally, when brian had used all the paper， he walked up to the airplane that had flown the farthest and picked it up。the next day was
