18.In face of global warming,much effort has been focused on reducing greenhouse gas emissions through a variety of strategies.But while much of the research and innovation has concentrated on finding less-polluting energy alternatives,it may be decades before clean technologies like wind and solar meet a significant portion of our energy needs.
In the meantime,the amount of CO2 in the air is rapidly approaching the limits proposed by the Intergovernmental Panel on Climate Change (IPCC)."As long as we're consuming fossil fuels,we're putting out CO2,"says Klaus Lackner,a geophysicist at Columbia University,"We cannot let the CO2 in the atmosphere rise indefinitely."
That sense of urgency has increased interest in capturing and storing CO2,which the IPCC says could provide the more than 50% reduction in emissions needed to reduce global warming."We see the potential for capture and storage to play an integral (基本的) role in reducing emissions,"says Kim Corley,Shell's senior advisor of CO2 and environmental affairs.That forward thinking strategy is gaining support.The U.S.Department of Energy recently proposed putting 1billionintoanew2.4billion coal-burning energy plant.The plant's carbon-capture technologies would serve as a pilot project for other new coal-burning plants.
But what do you do with the gas once you've captured it?One option is to put it to new uses.Dakota Gasification of North Dakota captures CO2 at a plant that converts (转换) coal into synthetic(合成的)natural gas.It then ships the gas 200miles by pipeline to Canada,where it is pumped underground in oil recovery operations.In the Netherlands,Shell delivers CO2 to farmers who pipe it into their greenhouses,increasing their production of fruits and vegetables.
However,scientists say that the scale of CO2 emissions will require vast amounts of long-term storage.Some propose storing the CO2 in coal mines or liquid storage in the ocean,Shell favors storing CO2 in deep geological structures such as saline (盐的) formations and exhausted oil and gas fields that exist throughout the world.

67.What does the author intend to tell readers?C
A.How to find more oil and natural gases.B.How to reduce greenhouse gas emissions.
C.How to deal with the greenhouse gas creatively.
D.How to make good use of solar and wind energy.
68.According to the passage,the following statements are true EXCEPT thatB.
A.the idea of capturing and storing CO2 is supported by the American government
B.it is widely accepted that the CO2 captured should be stored in deep geological structures
C.capturing and storing CO2 is intended to handle the problem with global warming
D.long-term storage of CO2 is no easy job because of the scale of CO2emissions
69.By using CO2,Dutch farmers have been able toA.
A.increase their production of fruits and vegetables  B.convert coal into synthetic natural gas
C.pump it underground in oil recovery operations  D.make exhausted oil and gas fields productive
70.How would you understand the underlined part in the third paragraph?C
A.It means a project training new pilots who will serve the new strategy.
B.It refers to the coal-burning energy plant that U.S government sponsors.
C.It implies the carbon-capture technologies will be popular once successful.
D.It shows the new idea of reduction of CO2 emissions needs a large sum of investment.

9.The 2016 Nobel Prize in Physics is shared by three scientists,the Royal Academy of Sciences announced in Stockholm on Tuesday.The Nobel Prize in Physics 2016 was divided,with one half awarded to David J.Thouless,the other half jointly to F.Duncan M.Haldane and J.Michael Kosterlitz"for theoretical discoveries of topological phase transitions and topological phases of matter.(物质拓扑相变和拓扑相)."
Haldane said he was"very surprised"at the news,adding that he was glad that their discoveries found something previously unnoticed by many,and that they revealed"more possibilities for looking for new materials."He particularly pointed out that a lot of work was still ongoing.
The year's prize amount is 8million Swedish krona (0.93 million US dollars),and will be split properly between the three winners.
The winners are given a sum of money when they receive their prizes,in the form of a document confirming the amount awarded.The amount of prize money depends upon how much money the Nobel Foundation (基金会) can award each year.The purse has increased since the 1980s,when the prize money was 880,000 SEK per prize.In 2009,the monetary award was 10million SEK(US$1.4million).In June 2012,it was lowered to 8million SEK.
If there are two winners of a particular prize,the award money is divided equally between the winners.If there are there,the awarding committee can choose to divide the money equally,or award one-half to one winner and one-quarter to each of the others.It is common for winners to donate prize money to benefit scientific,cultural,or charitable causes.

32.How much prize money does Thouless get?C
A.8 million Swedish krona.
B.6 million Swedish krona.

6.When Frida Kahlo's paintings were on show in London,a poet described her paintings as"a ribbon (丝带)around a bomb".Such comments seem to suggest Kahlo had a big influence(影响) on the art world of her time.Sadly,she is actually a much bigger name  today than she was during her time.
Born in 1907in a village near Mexico City,Kahlo suffered from polio(小儿麻痹症)at the age of seven.Her spine (脊柱)became bent as she grew older.Then,in 1925,her back was broken in several places in a school-bus accident.Throughout the rest of her life,the artist had many operations,but nothing was able to cure the terrible pain in her back.However,the accident had an unexpected side effect.While lying in her bed recovering,Kahlo taught herself to paint.
In 1929,she got married to Diego Rivera,another famous Mexican artist.Rivera's strong influences on Kahlo's style can be seen in her early works,but her later works from the 1940s,known today as her best works,show less influence from her husband.
Unfortunately,her works did not attract much attention in the 1930s and 1940s,even in her home country.Her first one-woman show in Mexico was not held until 1953.For more than a decade after her death in 1954,Kahlo's works remained largely unnoticed by the world,but in the 1970s her works began to gain international fame at last.

28.What does the phrase"a much bigger name"in paragraph 1most nearly mean?C
A.a far better artist
B.a far more gifted artist
C.a much more famous person
D.a much stronger person

B.Sympathy       
C.Worry

10.Ulrich's friend Anna was missing at school.His mother said that perhaps she had gone into hiding.That was the hope anyway-that the family had left on their own and had not been sent on one of the prison trains to Germany or Poland.So many people in his city had disappeared since the Nazis came to Amsterdam in 1940.The streets,once crowded with busy shoppers,were now filled with tanks and soldiers.
No one felt safe,except maybe the collaborators(通敌者).Who were they?Who would betray their friends and let their neighbors be arrested?Ulrich remembered his friend Anna:her father had a small business right down the road from his house.Her sister,Margot,was in the upper school,where Ulrich's sister was in her class.
When he walked to or from school,Ulrich studied the faces of the people on the street.Some looked concerned and cast their eyes downward as they walked,trying not to be noticed.His own parents had that look,like ghosts walking and wondering what had happened to them.The ones that bothered him were those who smiled,who acted like nothing was wrong."Were they blind?"he wondered.Worse were those who moved into the houses and took the businesses of their missing neighbors.They seemed too assured,too content.They may be Dutch,Ulrich thought,but they are the enemy,too.They were the ones who made the occupation easy.He hoped that when the war was over,the rightful owners would come back and toss them out on their ears.
School was not the same either.It was more than the missing students,though that was the biggest part of it.The teachers,who once seemed to know everything,were different,too.They seemed afraid to teach history,afraid that the authorities would not like what they said.They jumped when a student dropped a book.It was as if they all had to hold their breath.
It was nearly spring.Already tulips(郁金香)were fighting their way out of the cold ground.How many more winters,springs,summers,and falls would go by until they were free?Ulrich waited,and hoped that his friend Anna would soon come home.

56.What happened to Anna?D
A.She left on her own.B.She went into hiding.
C.She joined the army in Poland.D.She was missing for unknown reason.
57.The writer hates most the ones whoA.
A.occupied the neighbors'houses       B.acted like nothing was wrong
C.walked like ghosts                 D.looked concerned
58.The teachers jumped when a student dropped a book,because theyC.
A.were not confident                 B.disliked teaching history
C.were too cautious                  D.were enemies
59.Why did the writer mention tulips in the last paragraph?C
A.Tulips reminded Ulrich of his friend Anna.
B.It took a long time before tulips grew up.
C.Tulips stood for hopes in Ulrich's eye.
D.He liked springs best of all seasons.
7.A new study has found that social media could be affecting the sleep of young adults.The study is a project of researchers at the University of Pittsburgh's School of Medicine.They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less.
The researchers say doctors should ask young adults about their use of social media when treating sleep issues."This is one of the first pieces of evidence that social media use really can affect your sleep,"said Jessica C.Levenson.She is a postdoctoral researcher in the university's Department of Psychiatry.She was the lead author of a report on the study.The researchers set out to examine the connection between social media use and sleep among young adults.
The researchers wanted to find out how often young people used social media sites like Facebook,Twitter and etc..For the study,they gave questionnaires to nearly 1,800adults,aged 19to 32.On average,members of the study group used social media sites one hour a day.They also visited various social media accounts 30times per week.Thirty percent of the study's participants reported having serious problems with sleeping.Those people who used social media a lot were three times more likely to have a sleep disorder.And those who spent the most time on social media were two times as likely to suffer from sleep disturbances.
Frequent checking is big part of the problem.Levenson said the number of times a person visits social media is a better predictor of sleep problems than overall time spent on social media.If this is true,she adds,then practices that stop such behaviors may be most effective.
Researchers say social media can influence sleep patterns in a number of ways.People can lose sleep by staying up too late looking at social media.Sensitive issues argued about on social media can cause"emotional,cognitive or physiological"excitement.Using an electronic device can disturb a body's natural sleep rhythms because of the light coming from cell phones or computer screens.The researchers note that in some cases,young adults who have a hard time sleeping may use social media to help them fall asleep.
"It also may be that both of these hypotheses (假定) are true,"says Brian A.Primack.He is director of the Center for Research on Media,Technology and Health.He is also the study's senior author.Primack says,"Difficult sleeping may lead to increased use of social media,which may in turn lead to more problems sleeping.This cycle may be particularly problematic with social media.Many forms of social media involve interactive screen time that is stimulating (刺激) and rewarding and,for those reasons,can keep you awake."

68.From the results of the questionnaire,who are more likely to have a sleep problem?B
A.The participants aged from 19to 32.
B.The participants visiting social media frequently.
C.The participants using social media sites one hour a day.
D.The participants spending the most time on social media.
69.The main purpose of the passage is toC.
A.compare and evaluate
B.examine and reason
C.inform and explain
D.argue and conclude
70.What is the best title for the passage?A
A.Social Media Is Keeping Young Adults Awake
B.Difficult Sleeping Is Affecting Sleeping Patterns
C.Electric Devices Are Influencing Sleep Rhythms
D.Young Adults Are Suffering from Sleep Disorders.
