Everyone knows that the Internet has changed how business operate,governments function and people live.However,a new,less (41)H technological trend is just as transformative:"big data."Big data starts with the fact that there is a lot more information (42)D around these days than ever before and it is being put to extraordinary new uses.
Consider language translation,for example.When IBM first started to work on machine translation in the 1990s,it just fed a small number of high-quality translation into a computer and programmed it to infer which word in one language is the best (43)B for another.Although this (44)F revolutionized the task of translation,the result was far from being perfect.Then,in 2006,Google burst in.Instead of millions of pages of texts,the search giant (45)E billions,from corporate websites to documents in every language from the European Union.The result is that its translations are much better than IBM's were and it covers 65languages.Large amounts of (46)I data defeated small amounts of cleaner data.
Another good example of how big data can be (47)C helpful is online shopping.Using data collected from customer shopping habits,today,Amazon can (48)G who is most likely to purchase what and when.Details such as your history and wish list help the company gain a glimpse (一瞥) into your interests.Goods will then be dispatched to a logistics center(物流中心) near you and get packed before you even order,meaning that when you do make an online purchase,same-day (49)A would be possible.
With big data,instead of trying to understand exactly why an engine breaks down or why a drug's side effect disappears,researchers can instead collect and analyze massive quantities of information about such events and everything that is associated with them,looking for (50)K that might help predict future occurrences.
Big data answers not why but what.Finally,it will mark the moment when the"information society"finally fulfills the promise implied by its name.

解答 41.H  42.D  43.B  44.F  45.E  46.I  47.C  48.G  49.A  50.K
41.H 考查形容詞.visible此處是形容詞,意思是看的見的,根據(jù)句意visible technological trend 一種技術(shù)性趨勢即 big data.
 42.D  考查動詞.根據(jù)后句 it is being put to extraordinary new uses.可知,big data 這種科技正在被廣泛使用.
43.B  考查名詞.根據(jù)句子里for another可知,IBM 當初被認為是最好的翻譯工具選擇.
44.F  考查名詞.process此處是名詞,意思是過程,盡管這個過程革新了翻譯的任務(wù),但結(jié)果卻不是很滿意.
45.E  考查動詞.根據(jù)from corporate websites to documents in every language from the European Union可知,Google公司分析了數(shù)百萬的從公司網(wǎng)站到各種語言的文獻.
46.I  考查形容詞.Large amounts of massy data意思是大量的數(shù)據(jù)信息.
47.C 考查副詞.根據(jù)上文介紹可知,講述big data 的好處,所以此處enormously修飾helpful.
 48.G  考查動詞.determine此處是決定的意思,根據(jù)句意可知,Amazon可以判斷出誰要購買什么.
49.A  考查名詞.根據(jù)前句when you do make an online purchase當你在網(wǎng)上購物時,delivery意思是投送將成為可能.
50.K 考查名詞.pattern此處是名詞,樣式,根據(jù)句意researchers正在尋找能夠預(yù)測未來的一些模式.

點評 做完型填空時要求考生對文章通讀一遍,做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進行仔細分析,結(jié)合選項選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案.

7.In 1955,a man named Raymond Kroe entered a partnership with two brothers named McDonald.They opened a popular restaurant in California which sold food that was easy to prepare and serve quickly.Ha mburgers French fries,and cold drinks were the main food there.Kroc opened similar eating places under the same name,"McDonald's",and they were an instant success.He later took over the company,and today it is one of the most famous and successful"fast-food"in America and round the world.
Why was his idea so successful?Probably the most important reason was that his timing was right.In the 1950s,most married women stayed home to keep house and take care of their children.In the 1960s,many women returned to the workplace.This me ant that they had less time or energy to prepare meals,so they spent more on"TV dinners"and fast-food restaurants.Single parents also have little time to spend in the kitchen.People living alone also depend on this type of food,since cooking for one is often more trouble than it is worth.
Fast-food is not part of the diet of all Americans.Another trend of the 1960s,sometimes called the back-to-nature movement influenced many people to avoid food that was packaged or processed(處理).This preference for natural food continues to this day.
From the success of Raymond Kroc's fast-food business,we can say that social economic(經(jīng)濟)trends influence where and what we eat.
24."Cooking for one is often more trouble than it is worth"means thatB.
A.cooking for some people is worth more money
B.it is not worthwhile to take too much time to cook for one person
C.there are more problems when one person cooks

25.McDonald's success was mainly becauseD.
A.people living alone depend on fast-food
B.single parents have little time to spend in the kitchen
C.many women returned to the workplace in the 1960s
D.his timing was right
26.The main idea of the reading is thatB.
A.Raymond Kroc is the most successful fast-food business owner in the world
B.social and economic changes affect eating habits
C.fast-food is easy to prepare and serve quickly
D.Americans eat either fast-food or natural food.
