5. 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.What is the author’s attitude toward MOOCs?

2. 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.According to some doctors， ().

35. Questions 31 to 35 are based on the following passage.Lao Zi once said， “Care about what other people think and you will always be their prisoner.” People-pleasing， or seeking self-worth through others’ approval， is unproductive and an exhausting way to go through life.Why do we allow what others think of us to have so much power over how we feel about ourselves? If it’s true that you can’t please people all the time， wouldn’t it make sense to stop trying?Unfortunately， sense often isn’t driving our behavior.For social beings who desire love and belonging， wanting to be liked， and caring about the effect we have on others， is healthy and allows us to make connections.However， where we get into trouble is when our self-worth is dependent upon whether we win someone’s approval or not.This need to be liked can be traced back to when we were children and were completely dependent on others to take care of us: Small children are not just learning how to walk and communicate， they are also trying to learn how the world works.We learn about who we are and what is expected of us based on interactions with others， so， to a four-year-old， if Mommy or Daddy doesn’t like him or her， there is the danger that they will abandon them.We need to understand that when we desperately want someone to approve of us， it’s being driven by that little kid part of us that is still terrified of abandonment.As you become more capable of providing yourself with the approval you seek， your need for external validation will start to vanish， leaving you stronger， more confident， and yes， happier in your life.Imagine how much time we lose each moment we restrain our authentic selves in an effort to be liked.If we base our worth on the opinions of others， we cheat ourselves of the power to shape our experiences and embrace life not only for others but also for ourselves， because ultimately， there is no difference.So embrace the cliché (老话)and love yourself as it’s highly doubtful that you’ll regret it.What does the author advise us to do in the last paragraph?

A. 　Embrace life for ourselves and for others.

B. 　Base our worth on others’ opinions.

C. 　See our experiences as assets.

D. 　Love ourselves as we are.

2. Passage FourteenFor a long time， people have disagreed about whether golf is a sport or a game.On one side of the argument， people say that golf meets the dictionary definition of a sport， because it is a physical， athletic activity.They add that golf is recognized as a sport by sporting goods companies， athletic groups， fans， and the media.Also， golf’s inclusion in the Olympics in 2016 is more proof that it is a sport.On the other side， people say that golf is a game， not a sport.They say golf is not a very physical activity and can be played well by people who are overweight or injured.Also， golf was only recently added to the Olympics.For more than 100 years it was not included in the Olympic Games.For many， the Olympic Games serve as a measurement for whether an activity should be called a sport.Golf was first included in the Olympics in 1900.However， it was removed shortly thereafter because of a lack of participation and conflict with other golf events.Through the years， there were several attempts to bring golf back to the Olympics.It wasn’t until the 2016 Summer Olympics in Rio de Janeiro， Brazil that golf returned.Some say the return of golf does not prove that it is a sport.Rather， it only proves that the Olympics wanted to benefit from the star power of famous golfers like Tiger Woods.The disagreement continues today.Those who think golf is a sport point to pro-golfers like Woods， who are strong and fit.Those who disagree point to golfers like John Daly.He is a successful pro-golfer who once had health problems.So is golf a sport? The answer depends on who you ask——and whether that person owns a set of golf clubs.The overweight or injured people are mentioned in Paragraph 3 to ().
