unit 6 b卷一、阅读理解ai live in hollywood.you may think people in such an attractive，funfilled place are happier than others.if so，you have some mistaken ideas about the nature of happiness.many intelligent people still equate(使相等)happiness with fun.the truth is that fun and happiness have little or nothing in common.fun is what we experience during an act.happiness is what we experience after an act.it is a deeper，more longlasting emotion.going to an amusement park or ball game，watching a movie or television，are fun activities that help us relax，temporarily forget our problems and maybe even laugh.but they do not bring happiness，because their positive effects end when the fun ends.i have often thought that if hollywood stars have a role to play，it is to teach us that happiness has nothing to do with fun.these rich，beautiful individuals have constant access to exciting parties，fancy cars，expensive homes，and everything that spells“happiness”but in memoir(回忆录)after memoir，celebrities reveal the unhappiness hidden beneath all their fun：depression，alcoholism，drug addiction，broken marriages，troubled children，longtime loneliness.the way people hold on to the belief that a funfilled，painfree life equates happiness actually decreases their chances of ever attaining real happiness.if fun and pleasure are equated with happiness，then pain must be equated with unhappiness.but，in fact，the opposite is true：more often than not，things that lead to happiness involve some pain.as a result，many people avoid the very endeavors or efforts that are the source of true happiness.they fear the pain inevitably brought by such things as marriage，raising children，professional achievement，religious commitment，charitable work，and selfimprovement.1according to the passage，“fun activities”mentioned in the 2nd paragraph_.aare the things we do before we find happinessbmay help us relax and forget our problems sometimescwill lead us to the true happinessdcould provide longlasting positive effects2in the authors opinion，those hollywood stars_.apossess happiness because they are rich and famousbexperience almost all kinds of happy thingsctell us happiness isnt equal to fun using their own storiesdhave to suffer a lot before they become successful3it is difficult for people to find real happiness because_.athey believe happiness is the fun life without painbthey find pain equals unhappinesscthey fear to lose what they already have in lifedthey are afraid all their efforts were in vain4the main purpose of the text is to_.adescribe the difference between happiness and funbshow the true meaning of happinesscencourage people to pursue fun activitiesdadvise people to find their real lifebwhy do human beings still risk their lives underground and doing one of the dirtiest and most dangerous jobs in the world? a small group of engineers and robotics experts envision(展望)a day in the nottoodistant future when robots and other technology do most of the dangerous mining work.one of the first mining robots was developed five years ago at carnegie mellon universitys robotics institute.it was called groundhog and it looked like a golf cart.it used lasers(激光)to“see”in dark tunnels and map abandoned minessome of the most dangerous work in the business.the latest prototype is called cave crawler.its a bit smaller than groundhog，and even more advanced.it can take photos and videos and has sensors that can detect the presence of dangerous gases.incredibly，the robot has a real sense of logic.if it comes across an obstacle it gets momentarily confused.it has to think about what to do and where to go next.sometimes it throws_a_fit just like a real person.myles and his colleagues hope that robots like cave crawler will one day be used in rescue operations.“a robot could speed up the rescue process by doing reconnaissance(侦察)，”says chuck whittaker，a robotics engineer at carnegie mellon.“the robot can go ahead and，with its sensors，report what it has found and whether it is safe for humans to proceed.”using robots in rescue operations，though，is problematic.the lasers that guide the robots dont work in smoky environments so the engineers at carnegie mellon have experimented with sonar(声呐)and radar guidance systems，and with some success.some experts predict that robots in mines will serve much of the same function that they do in the automotive industry.the robots do the most repetitive and dangerous jobs，but wont get rid of the need for human workers.5the underlined phrase“throws a fit”in paragraph 3 probably means“_”agets angrybgets shockedcbecomes confused dbecomes cheerful6the latest robot is more advanced than groundhog mainly because_.ait can map abandoned minesbit can see in the dark tunnelscits smaller than groundhogdit has a real sense of logic7we can infer from the last paragraph that _.athe mining robots will have a very bright futurebrobots in the automotive industry must be improvedcthere will be no need for human workers in minesdrobots in mines will cost a lot8what can guide the robots in smoky environments?athe lasers.bsonar and radar guidance systems.ccommand guidance systems.dimage matching guidance systems.二、任务型读写阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。what do you usually use your cellphone for？calling friends or sending them text messages?as technology develops，nowadays cellphones can do much more than that.they have become an allinone cellphone.a typical example is apples phone.the touch screen cellphone plays music，connects to the web，sends emails and takes photos.more than 1 million apples phones have been sold since it was sold in june.“todays young people enjoy using all kinds of digital functions，such as those of a music player，a camera and even a computer.an allinone cellphone is easy to carry.that is the goal of developing a technology to make our lives more convenient，simple and relaxed，”said professor ding shouqian at nankai university.however，the allinone cellphones come with some problems.users have complained that they are too complicated to use and that their battery life is too short.cellphone producers say that they are working hard to make their phones even better.its very convenient to use it.“we are trying to make the cellphones in a way that people can quickly move from phoning to taking pictures to listening to music，”said alastair curtis，nokia s chief designer.“if you look at the nokia 3250 model，it has a twisting(转动)bottom.so you twist it half a turn，and its in camera mode.you twist it another 90 degrees，and its in music player mode.”japanese companies such as toshiba and fujitsu are also working to develop a new kind of battery for cellphone.if all the problems are solved in the future，allinone phones will change our lives for the better.title：the allinone cellphonesituationwith the 1._ of technology，nowadays cellphones can do much more than that.functions*it plays music.*it is 2._ to the web.*it can 3._ emails and take photos.*it can even be used as a 4._.5._*the cellphones are 6._ carried and used.*the cellphone is designed to bring people much more 8._：simplicity and relaxation.problems*they are too complicated to use.*their battery life is short.7._*to make it easy and 9._ to move from one mode to another.* the companies make better batteries that last 10._.参考答案与解析课时作业(十二)unit 6b卷一、阅读理解解题导语
