20．We have entered a new age of embedded（嵌入式的），intuitive（直覺(jué)的） computing in which our homes，cars，stores，farms，and factories have the ability to think，sense，understand，and respond to our needs．It's not science fiction，but the dawn of a new age．
Most people might not realize it yet，but we are already feeling the impact of what's known as the third wave of computing．In small but significant ways it is helping us live healthier and more secure lives．If you drive a 2014Mercedes Benz，for example，an"intelligent"system tries to keep you from hitting a pedestrian．A farmer in Nigeria relies on weather sensors that communicate with his mobile device．Forgot your medicine？A new pill bottle from AdhereTech reminds you through text or automatic phone messages that it's time to take a pill．
Technology is being integrated（融入） into our natural behaviors，with real-time data connecting our physical and digital worlds．With this dramatic shift in our relationship to technology，companies can adapt their products and services．
To understand how revolutionary the third wave is，we ought to consider how far we have come．The first wave began when companies started to manage their operations through mainframe computer systems over 50years ago．Then computing got"personal"in the 1980s and the 1990s with the introduction of the PC （personal computer）．For the most part，computing remained immobile and lacked contextual awareness．
In computing's second wave，mobile computing and the smartphone took center stage．Billions of people，some of whom might not have had access to clean water，electricity，or even housing，were connected．Developers created applications and provided consumers with access to just about everything through their phone at the cost of a monthly data plan．
As the third wave keeps developing，designers must meet the demands of consumers who want to experiment with new technology．
Historically，designers have focused their attention on a product's form and function．While that still matters，of course，the definition of a meaningful user experience has expanded significantly and will continue to do so．Instead of creating a single product，designers will need to imagine a series of connected products and services that have awareness of each other and their surroundings．

74．Why are three examples given in Paragraph 2？D．
A．To tell us that human beings are smarter and smarter．
B．To illustrate the importance and necessity of technology．
C．To prove that we are living healthier and more secure lives．
D．To show the impact of the third wave of computing on our life．
75．In the first wave of computingD．
A．companies'operations were reliable on computer systems
B．computing had awareness of people's needs in the context
C．people could have access to computing almost everywhere
D．it was possible for people to experience computing at home
76．Which of the following is a situation in the third wave of computing？C．
A．There's no need to create a single product．
B．The definition of the user experience is more significant．
C．Products and services are not independent of each other．
D．The products'form and functions are no longer important．
77．What can we conclude from the passage about the new age we are facing？B．
A．There's a shift of attention from people's physical worlds to their digital worlds．
B．There's closer relationship between technology and people's natural behaviours．
C．People live more happily with the convenience brought by advanced technology．
D．People become lazier with the products that can think and respond to their needs．

分析 本文主要講述了三次計(jì)算機(jī)革命給我們帶來(lái)的影響，以及如今技術(shù)仍在發(fā)展，設(shè)計(jì)師們將會(huì)設(shè)計(jì)出產(chǎn)品與服務(wù)互相依靠的新產(chǎn)品．

解答 74．D   細(xì)節(jié)理解題，由第二段Most people might not realize it yet，but we are already feeling the impact of what's known as the third wave of computing．可知我們已經(jīng)受到了第三次計(jì)算機(jī)革命的影響，第二段向我們說(shuō)明我們受到了哪些影響，故選D．
75．D   細(xì)節(jié)理解題，由第四段Then computing got"personal"in the 1980s and the 1990s with the introduction of the PC （personal computer）．For the most part，computing remained immobile and lacked contextual awareness．可知第一次計(jì)算機(jī)革命的時(shí)候電腦是固定不動(dòng)的，因此人們可以在家體驗(yàn)，故選D．
76．C   理解推斷題，由最后一段Instead of creating a single product，designers will need to imagine a series of connected products and services that have awareness of each other and their surroundings．可知產(chǎn)品與服務(wù)不是相互獨(dú)立的，故選C．
77．B  細(xì)節(jié)理解題，由第二段If you drive a 2014Mercedes Benz，for example，an"intelligent"system tries to keep you from hitting a pedestrian．A farmer in Nigeria relies on weather sensors that communicate with his mobile device．可知技術(shù)與人們的自然行為之間有著緊密聯(lián)系，故選B．

點(diǎn)評(píng) 做閱讀理解時(shí)要快速的瀏覽全文，把握文章主旨大意，帶著問(wèn)題回到原文，尋找細(xì)節(jié)或概括相應(yīng)的答案，最后理清作者寫作思路．

Nearly 20 million Americans will find themselves prisoners of basketball festival madness．The fun comes partly from guessing the winners for every game．Friends compete against friends．（38）AColleagues against bosses．
Big-name schools are usually favored to advance into the tournament．But each year there are dark horses from little-known universities．
This adds to the madness．Watching a team from a school with 3，000 students beat a team from a school with 30，000，for many Americans，is an exciting experience．Two years ago，the little-known George Mason University was one of the final four teams．（39）GCollege basketball players are not paid，so the game is more about making a name for their university and themselves．（40）CAbout 4billionwillbespentgambling（賭）ontheevent．AccordingtoMediaLifemagazine，theeventwillbringin 500 million in advertising income this year，topping the post-season income of every US professional league，including that of the NBA．

9．閱讀下面的短文，然后按照要求寫一篇150詞左右的英語(yǔ)短文．
World Reading Day was set up by the UNESCO in 1995to encourage people，especially teenagers，to discover the pleasure of reading．
Many countries celebrated World Reading Day．Take the UK as an example，on that day，millions of schoolchildren can buy books of special price，a much lower price than usual，in any bookstore．It has been done every year since 1998．World Reading Day 2010in the UK will take place on Thursday 4th March．Please note that this date applies to the UK and Ireland only．The initiative is so well established in schools there that they want to make sure that the Day happens in term time to really make the most of this opportunity to celebrate books and reading．Most other countries hold World Reading Day on 23rd April every year．
World Reading Day is also celebrated in China．Chinese Premier Wen Jiabao，an avid reader，does lots of reading every day though he is very busy．On World Reading Day 2009he encouraged citizens to do more reading．Wen suggested that young people should spend more time reading．"Books cannot change the world，but people can change the world by changing themselves through reading．"
Reading can benefit people in many ways．Reading helps us to follow the latest developments of science and technology．Reading gives us information about other cultures and places of the world．Reading is also one of the most important ways to learn a foreign language like English．
"Reading makes a full man"（Bacon，1597）．Books，magazines，newspapers and other kinds of reading materials can help us to know more about the outside world and perfect us．Therefore，it is necessary for us to spend time on reading every day．

2．以約120詞就"Reading-A Bright Way to A Better life"發(fā)表你的看法，內(nèi)容包括：

As we know，knowledge may be acquired through many ways，the best of which is reading．In the age of high technology，reading deserves to be paid attention to．
To begin with，it is the most flexible way of getting information．Many people think it not only helps them better understand society as well as nature，but also broadens their horizon．Additionally，reading，to some degree，is of great benefit to interpersonal communication apart from self-improvement．It can also enrich our life and bring people pleasure．What's more，reading is also regarded by many as a means of better survival．
Books are to mind what food is to body．However，not every book is worthy of being read．Some may mislead readers．So keep in mind that choosing a good book is likemaking a good friend．Besides，reading is supposed to be done in a proper period of time，for example，in our spare time，thus not disturbing our work or study．As long as we insist on reading，we can get improved gradually．
Personally，I appreciate reading classical literature in my spare time，which provides me with a thorough understanding of life and society．Through practicing reading between the lines and beyond the lines，I find my comprehension ability stably improved．Perhaps in the near future，I'm not merely a reader but also a writer．．
