4. Passage ElevenDoctors say anger can be an extremely damaging emotion, unless you learn how to deal with it.They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and breast cancer.Anger is a normal emotion that we all feel from time to time.Some people express anger openly in a calm and reasonable way.Others burst with anger, screaming and yelling.But still others keep their anger inside.They cannot or will not express it.This is called (repressing)anger.For years some doctors claim that both repressing and expressing anger can be dangerous.They say that in both situations the brain of an angry person releases the same hormones (荷尔蒙).They spend the heart rate, raise blood pressure or sugar level in the blood.As a result, the angry person feels excited and is ready to react.The violent reaction may lead to high blood pressure.However, some other doctors argue that repressing anger is more dangerous to a person’s health than expressing it.They believe that those who keep their anger inside may face a greater danger of heart disease.Most doctors agree that it is important to learn how to deal with anger.They say the first step is to admit that you are angry and recognize the real cause of the anger, then decide if the cause is serious enough to get angry about.If so, you should not express your anger immediately and try to wait until your anger has cooled down, so that you are able to express yourself calmly and reasonably.They also believe that a good way to deal with anger is to find humor in the situation that has made you angry.After all, it is much healthier to laugh than to get angry.The costs of tuition and housing in Lewis and Clark College are ().

2. 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 Paragraph 2, online dating ().

2. 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.In Para.2, the author stresses ().

38. Questions 36 to 40 are based on the following passage.Some people have said aging is more a slide into forgetfulness than a journey towards wisdom.However, a growing body of research suggests that late-in-life learning is possible.In reality, education does an aging brain good.Throughout life, people’s brains constantly renovate themselves.In the late 1960s, British brain scientist Geoffrey Raisman spied growth in damaged brain regions of rats through an electron microscope; their brains were forging new connections.This meant brains may change every time a person learns something new.Of course, that doesn’t mean the brain isn’t affected by the effects of time.Just as height usually declines over the years, so does brain volume: Humans lose about 4 percent every decade starting in their 40s.But that reduction doesn’t necessarily make people think slower; as long as we are alive and functioning, we can alter our brains with new information and experiences.In fact, scientists now suspect accumulating novel experiences, facts, and skills can keep people’s minds more flexible.New pathways can strengthen our ever-changing mental structure, even as the brain shrinks.Conventional fixes like word puzzles and brain-training apps can contribute to mental durability.Even something as simple as taking a different route to the grocery store or going somewhere new on vacation can keep the brain healthy.A desire for new life challenges can further boost brainpower.Research about aging adults who take on new enterprises shows improved function and memory as well as a reduced risk of mental disease.Openness—a characteristic defined by curiosity and a desire for knowledge—may also help folks pass brain tests.Some folks are born with this take-in-the world attitude, but those who aren’t as genetically gifted aren’t necessarily out of luck.While genes can encourage an interest in doing new things, a 2012 study in the journal Psychology and Aging found completing reasoning tasks like puzzles and number games can enhance that desire for novel experiences, which can, in turn, refresh the brain.That’s why brain scientist Richard Kennedy says “It’s not that old dogs can’t learn new tricks.It’s that maybe old dogs don’t realize why they should.”What is one thing that helps maintain the health of our brain even as it shrinks?
A. Doing daily routines by conventional means.
B. Avoiding worrying about our mental durability.
C. Imitating old dogs’ way of learning new tricks.
D. Approaching everyday tasks in novel ways.

33. 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 questions arise from living big?
A. Questions related to moral principles.
B. Questions having to do with labor cost.
C. Questions about what lifestyle to promote.
D. Questions concerning housing development.

3. Passage NineteenA 3-year-old boy who was lost in the woods for two days is now safe at home.But Casey Hathaway told his rescuers that he was not alone in the rainy, freezing cold woods.He said he was with a friend——a bear.The child went missing on January 22 while playing with friends at his grandmother’s house in the southern state of North Carolina.When the other children returned to the house and Casey did not, the family searched the area for almost an hour before calling the police.Police formed a search and rescue team to look for the young boy in the nearby woods.But two days went by and still——no Casey.The woods of North Carolina are home to many black bears, like this one.It seems one of them helped a little boy while he was lost in the woods.Then on January 24, someone called the police saying they heard a child crying in the woods.Police followed up on the information and found Casey at about 9:30 that night.They pulled him out of some briar (荆棘).He was in good health.Police Officer Chip Hughes said that Casey did not say how he was able to survive in the woods for two days in the cloud, rainy weather, but that “he did say he had a friend in the woods that was a bear that was with him.”Hundreds of people helped in the search and rescue efforts, including some 600 volunteers, federal police and members of the military.Hughes told reporters that at no point did he think Casey had been kidnapped (绑架).Doctors at Carolina East Medical Center treated Casey for minor injuries.He was then released to his family on January 25.After receiving the call, the police ().
