35. 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 does the author advocate for people to live well?

A. 　Finding ways to turn private spaces into public ones.

B. 　Building more houses affordable to those less affluent.

C. 　More public spaces created for everyone to enjoy.

D. 　All amenities made accessible to the rich and the poor alike.

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)().

8、I have always wondered at the passion many people have to meet the celebrated(名人).The “advantage” you acquire by being able to tell your friends that you know famous men proves only that your are yourself of small account.The celebrated develop a technique(技艺，技能)to deal with the persons they come across.They show the world a mask， often an impressive one， but take care to conceal(隐藏)their real selves.They play the part that is expected from them， and with practice learn to play it very well， but you are stupid if you think that this public performance of theirs corresponds(符合)with the man within.

8.The project ()by the end of 2000， will expand the city＇s telephone network to cover 1，000，000 users.

40. Questions 36 to 40 are based on the following passage.Most of us in the entrepreneurial community are blessed — or cursed — with higher-than-average ambition.Ambitious people strongly desire accomplishments and are willing to take more risks and spend more effort to get them.Overall， this is a positive quality， especially for people trying to build their own businesses.Apparently， if you’re more naturally driven to set goals， you are more likely to succeed.Actually， this isn’t always the case.In fact， in some cases， extreme ambition may end up doing more harm than good.One major side effect of excessive ambition is the tendency to focus too determinedly on one particular vision or end goal.This is problematic because it hinders your ability to adapt to new circumstances， which is vital if you want to be a successful entrepreneur.If a new competitor emerges to threaten your business， you may need to change direction， even if that means straying from your original vision.If you have too much ambition， you’ll find this hard， if not impossible.Few people are successful when they try to build their first brand.Unfortunately， for the most ambitious entrepreneurs， a failure is seen as disastrous， and impossible to recover from.It’s a clear departure from the intended plan toward the intended goal.For people with limited ambition， however， failure is viewed as something closer to reality.Remember， failure is inevitable， and every failure you survive is a learning experience.Ambitious people tend to be more materialistically successful than their non-ambitious counterparts.However， they’re only slightly happier than their less-ambitious counterparts， and tend to live significantly shorter lives.This implies that even though ambitious people are more likely to achieve conventional “success，” such success means nothing for their health and happiness—and if you don’t have health and happiness， what else could possibly matter?Clearly， some amount of ambition is good for your motivation.Without any ambition， you wouldn＇t start your own business， set or achieve goals and get far in life.But an excess of ambition can also be dangerous， putting you at risk of burnout， stubbornness and even a shorter life.What does the author advise us to do concerning ambition?

A. 　Distinguish between conventional success and our life goal.

B. 　Follow the example of the most ambitious entrepreneurs.

C. 　Avoid taking unnecessary risks when starting a business.

D. 　Prioritize health and happiness over material success.
