2. Passage FifteenBig data can be defined as information that is too big or complex to be contained or processed by any one machine or person.As a student at the University of Sussex， Julian Dailly had two majors——English and philosophy.When he completed his studies， Dailly wondered how he would ever earn a living in a world filled with machines and technology.Now， he is part of the big data industry that includes Google and Facebook.Dailly’s research company， Monar Consulting， started three years ago with five employees.The company’s earnings have increased by 25% each year.It now employs 90 people.“What we do here is we try to discover what’s meaningful for people and link that to their economic behavior，” Dailly said.He noted the importance of working with people with different skills.“We have people from traditional research backgrounds， in addition to some in social sciences， economics， people from tech backgrounds， and sales people，” Dailly said.Companies like Dailly’s employ recent college graduates.The industry profits from the ideas of these young men and women.New forms of data also make it possible for some observers to predict the future.They are more valuable to companies than the traditional forms of data recording or reporting.“We have access to the core information inside people’s heads，” Dailly said， “They tell you what people are going to do as opposed to what they’ve done.That helps people take proper action in advance.This makes it much more useful for strategy.”Julian Dailly dismisses concerns that computers have finally taken control of our daily lives.“Some may worry that humans will be allowed to be replaced by machines.I think it’s a fantasy.”Dailly’s company focuses on businesses in ().

4. Passage Twenty-SevenOut of all the students who enroll in a massive open online course (MOOC)， only about 5 percent complete the course and receive a certificate of accomplishment.This statistic is often cited as evidence that MOOCs are fatally flawed (有缺陷的)and offer little educational value to most students.Yet more than 80 percent of students who fill out a post-course survey say they met their primary objective.How do we look at these two facts? We’re used to focusing on completion rates in higher education， but they’re not the only—or even the most meaningful—indicator of engagement in open online courses.With no cost to enroll， no punishment for dropping out， and little reward for actually earning a certificate， MOOCs are fundamentally different from traditional classes—and students use them in fundamentally different ways.Data from more than 1.8 million students enrolled in 36 MOOCs offered by the University of Pennsylvania show that students treat MOOCs like a buffet (自助餐)， sampling the material according to their interests and career goals.Some are curious about the subject matter and just watch one or two video lectures; others use the discussion forums to connect with their intellectual peers around the world.Of all enrolled students， nearly 60 percent watch at least one video， complete at least one assignment， or post at least once in a forum.So focusing on the tiny fraction of students who complete a MOOC is misguided.The more important number is the 60 percent engagement rate.Students may not finish a MOOC with a certificate of accomplishment， but the courses nonetheless meet the educational goals of millions.The sentence “students treat MOOCs as a buffet” (Para.3)().

5. Passage Twenty-FiveOnline dating has just been revealed to be one of the most common ways to start a relationship.But new research reveals that the concept is still highly flawed (有缺陷的).An analysis of 400 studies into online dating shows that while it offers access to plenty of other singles， users can be overwhelmed and put off by the volume of choice， defeating the purpose.The research， by Northwestern University and published in the journal Psychological Science in the public interest， found that the processes involved don’t lend themselves to forming strong relationships.The findings also indicated that the concept of an online profile (介绍)is not entirely useful and “can result in treating potential partners as mere objects”.Lead author Eli.J.Finkel explained， “Online dating is a terrific addition for singles to meet.However， there are two problems.” First， studying over seemingly endless lists of profiles of people one does not know， as on Match.com， does not reveal much about them.Second， it “overloads people and they end up shutting down，” he said.He compared it to shopping at “supermarkets of love” and said psychological research shows people presented with too many choices tend to make lazy and often poor decisions.The study’s authors also questioned the algorithms (算法)employed by sites such as eHarmony.com to match people based on their interests or personality—comparing it to having a real estate agent of love.While the algorithm may reduce the number of potential partners from thousands to a few， they may be as unsuitable for each other as two people meeting at random， Dr.Finkel explained， adding the chances are no better than finding a relationship by walking into any bar.“There’s no better way to figure out whether you’re a match with somebody than talking to them over a coffee or beer，” Dr.Finkel said.According to Dr.Finkel， what is the best way to find a match?

32. Questions 31 to 35 are based on the following passage.The United States is facing a housing crisis: Affordable housing is inadequate， while luxury homes abound (充裕)， and homelessness remains a persistent problem.Despite this， popular culture and the housing industry market happiness as living with both more space and more amenities (便利设施).Big houses are advertized as a reward for hard work and diligence， turning housing from a basic necessity into a luxury.This is reflected in our homes.The average single-family home built in the United States before 1970 was less than 1，500 square feet in size.By 2016， the average size of a new， single-family home was 2，422 square feet.What’s more， homes built in the 2000s were more likely than earlier models to have more of all types of spaces: bedrooms， bathrooms， living rooms， dining rooms， recreation rooms and garages.There are consequences of living big.As middle-class houses have grown larger， two things have happened.First， large houses take time to maintain， so cleaners and other low-wage service workers are required to keep these houses in order.Second， once-public spaces， where people from diverse backgrounds used to come together， have increasingly become privatized， leading to a reduction in the number of public facilities available to all， and a reduced quality of life for many.Take swimming pools.While in 1950， only 2，500 U.S.families owned pools， by 1999 this number was 4 million.At the same time， public municipal pools were often closed， leaving low-income people nowhere to swim.The trend for bigger housing thus poses ethical questions.Should Americans accept a system in which the middle and upper classes enjoy a luxurious lifestyle， using the low-wage labor of others? Are we willing to accept a system in which an increase in amenities purchased by the affluent means a reduction in amenities for the poor?I believe neither is acceptable.We must change the way we think: living well does not need to mean having more private spaces; instead， it could mean having more public spaces.A better goal than building bigger houses for some is to create more publicly accessible spaces and amenities for all.What is one of the consequences of living big?

A. 　Many Americans’ quality of life has become lower.

B. 　People from diverse backgrounds no longer socialize.

C. 　People no longer have access to public swimming pools.

D. 　Many Americans’ private life has been negatively affected.

3. Passage Twenty-EightOn November 19， 1863， Abraham Lincoln went to Gettysburg in Pennsylvania to speak at the National Soldiers Cemetery.The Civil War was still going on.There was much criticism of President Lincoln at the time.He was not at all popular.He had been invited to speak at Gettysburg only out of politeness.The principal speaker was to be Edward Everett， a famous statesman and speaker of the day.Everett was a handsome man and very popular everywhere.It is said that Lincoln prepared his speech on the train while going to Gettysburg.Late that night， alone in his hotel room and tired out， he again worked briefly on the speech.The next day Everett spoke first.He spoke for an hour and 57 minutes.His speech was a perfect example of the rich oratory of the day.Then Lincoln rose.The crowd of 15，000 people at first paid little attention to him.He spoke for only nine minutes.At the end there was little applause.Lincoln turned to a friend and remarked， “I have failed again.” On the train back to Washington， he said sadly， “That speech was a flat failure， and the people are disappointed”.Some newspapers at first criticized the speech， but little by little as people read the speech， they began to understand better.They began to appreciate its simplicity and its deep meaning.It was a speech which only Abraham Lincoln could have made.Today， every American school child learns Lincoln’s Gettysburg Address by heart.Now everyone thinks of it as one of the greatest speeches ever given in American history.It can be inferred from the text that ().

35. Questions 31 to 35 are based on the following passage.To write his 2010 book， The 5-Factor World Diet， nutritionist Harley Pasternak traveled to the healthiest countries around the world to learn more about what made their meals extra nourishing.He noted that Japanese people ate a wonderful variety of seaweeds， and that Chinese people tried to include at least five different colors in every meal.Pasternak also came away with some valuable observations about how different the North American way of life was， compared with many other countries.For starters， Americans eat much bigger portions than people in other countries.“We don’t prioritize eating seasonally or locally， and we also add lots of salt， sugar and thickening agents to our foods，” explained Pasternak.Contrast that to the healthy Mediterranean， Nordic and Okinawan diets listed in Pasternak＇s book.They all seem to stick to the ethos (特质)of regional， seasonal produce.For example， a traditional Mediterranean diet includes fruits， vegetables， whole grains， nuts and olive oil as the main components of nutritional intake.Fish， chicken and red wine make moderate appearances， while red meat， salt and sugar are used much less often.The benefits of a traditional Mediterranean diet have been studied since the 1970s， and researchers have found that living that olive oil life can help people lose weight， lower their heart disease risk and reverse diabetes.Most other healthy eating cultures also make meals an event—say， multiple courses around the family table， or a glass or two of red wine at a long lunch—opposed to hastily wolfing down handfuls of cereal above the kitchen sink and calling it dinner.Each of the healthy eating cultures has its own unique feature.But Pasternak did take note of one unifying factor in all of the healthy societies he observed.“The only overlapping feature in most of these healthy countries is that they all walk way more than the average American，” said Pasternak.“So really， regardless of what you’re eating， if someone’s walking four miles more than you each day， they are going to be a lot thinner and live a lot longer than you.”Compared with the average American， people in healthy societies ( ).
