10．Advice to"sleep on it"could be well founded，scientists say．After a good night's sleep a problem that couldn't be solved the night before can often appear more manageable，although the evidence（证据）until now has been personal experience．But researchers at the University of Luebek in Germany have designed an experiment that shows a good night's sleep can improve insight（洞察力）and problem-solving．
"If you have some newly-got memories in your brain，sleep acts on these memories and rebuild them，so that after sleep the insight into problem which you could not solve before increases，"said Dr Jan Born，a neuroscientist（神经病学专家）at the university．To test the theory，they taught volunteers two simple rules to help them turn some numbers into a new order．There was also a third，hidden rule，which could help them increase their speed in solving the problem．The researchers divided the volunteers into two groups：half were allowed to sleep after the training while the rest were forced to stay awake．Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group．"Sleep helped，"Born said in a telephone interview．"The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep，so it can act on the problem．"But Born admitted that he and his team don't know how rebuilding of memories occurs or what governs it．Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can help develop creative thinking．Although the role of sleep in human creativity will still be a mystery，the research gives people good reason to fully respect their periods of sleep，they added．

A．to plantingB．to plantC．plantD．planting
1．Who is the most powerful woman in the world？According
to the US media，it's Janet Yellen，or at least she's about to be．
On Oct 9，2013，US President Barack Obama nominated
（提名）Yellen to serve as the next US Federal Reserve （the Fed，美联储）chair．If confirmed by the Senate，Yellen will becomethe first woman to serve in the top spot．
Aged 67，silver-haired and tiny，Yellen is said to be themost qualified nominee ever．She chaired President Bill
Clinton's Council of Economic Advisers，taught at Harvard and Berkeley，and was president of the Federal Reserve Bank of San Francisco．She is currently the Fed's vice chair．
Many think Yellen is the right choice to deal with the challenges the Fed now faces：First，to bring interest rates back to more normal levels without triggering a new recession（衰退）．Second，to reduce the US unemployment rate，which remains at historically high levels．
A CNN opinion piece says Yellen is unusual for an economist of her caliber（才干）．"She has kept her eyes on what's critical-the people．Her research has centered on unemployment，on the best way to modulate（调整）government policies to benefit the people．"
Past records also show that Yellen is exceptionally good at predicting where the economy is headed．An article in The Washington Post points out that she was one of the few voices at the Fed in December 2009warning about the subprime crisis（次贷危机）and the following recession．
The reason why Yellen will be the most powerful woman in the world has to do with the unique position of the Federal Reserve，explains an article on Quartz，a US news outlet for business people in the new global economy，
First of all，the Fed is independent．Unlike US Secretaries of State Madeleine Albright and Hilary Clinton，the decisions made by the organization Yellen will lead next year are not subject to approval by anyone in the government．
Within the Fed，the chair alone sets the agenda．The Fed chairperson has huge influence on
monetary policy（货币政策）and financial regulation．And don't forget how powerful the Fed itself is．It controls the money supply in the world's largest economy．The Fed's interest rate decisions don't just set the course for the US economy，its decisions set the course for the world economy，too．
Because of globalization，Yellen's decisions will affect everyone around the world，says an article in The Atlantic，making her even more powerful than some great women rulers in history，including Elizabeth I of England and China's Wu Zetian．For example，the article continues："If Yellen even just talks about slowing down the Fed's bond-buying，Europe's troubled economies are likely to see their interest rates rise，and emerging markets，some of which，like India and Indonesia，used foreign capital to fund their current account deficits（赤字），are likely to see their currencies collapse．"

59．According to the passage，which of the following is NOT the reason for Yellen's nomination？C
A．Yellen's professional experiences．
B．Yellen's ability to deal with the challenges the Fed faces．
C．Yellen's educational background．
D．Yellen's remarkable competence as an economist．

B．Yellen gets full support from Obama
C．Yellen holds a unique position in the government
D．the Fed possesses great power and influence

A．Optimistic．  B．Negative．  C．Understanding．  D．Doubtful．

18．Cancun is a seaside town in Mexico，where most tourists come here to enjoy the beach，water sports and night life．In fact，it is so modern and Americanized that you might think you were in southern California or Florida．
But just a short two-hour hike from the town lie the ruins of the city of Chichen-Itza，one of the capitals of the lost Maya（玛雅）civilization．The center of the ruins of this city is the pyramid of El Castillo．The ancient Mayan religious people climbed this pyramid during festival to honor the Sun god．Tourists today climb it to view the architectural achievements of Chichen-Itza and to prove their fearlessness of heights and steep （陡峭的）climbs．There is a sign in Spanish，admonishing visitors"It's dangerous to go up．"I gladly ignored it and started my climb．
The climbing was tough．The steps were higher than one might normally take．，but the climb was not fearful at all．From the top of the pyramid，I had a wonderful view of the ruins of this Mayan city．What was most striking to me was that just beyond the ruins of splendid structures，gardens，temples and what looks like a modern sports stadium，you could only see forests for miles and miles．It was almost as if some race had mysteriously come out of nowhere，built it up and then suddenly disappeared from the planet，leaving only stones in its space．
The only remains on the top of the pyramid were the Temple of Kukulcan．During the festivals to worship the Sun god，only the high ranks would have the right to enter this temple．
After shooting a few pictures，I realized it was time to go down．Only then did I discover that what people fear about the climb is not the trip going up，but the way going down．I saw a few brave souls who were walking down as if they were in their own house．Looking down at the steepness of the pyramid，I desperately feared this great height．My first desire was to joke with a few people，"Where is the elevator（电梯）？"I figured that a civilization that was this advanced would have had the foresight（预见） to construct an elevator．Lacking such modern equipment，I had to use the chain provided by the Mexican tourist authorities and climb down on all fours．
My climb was complete eventually．I quickly got on the bus back to my comfortable hotel．Leaving the ruined city，I was still wondering what possibly happened long ago．But a few hours later，I was back in the modern world drinking cocktails on the beach，bathing in the sunshine before boarding the plane and waiting for my trip back home to the US，where all the modern things such as elevators are available!
62．Why did the writer pay a visit to the ruined city of Chichen-Itza？A
A．He wanted to climb the pyramid of EL Castillo and know about the Mayan civilization．
B．He would got to the Temple of Kukulcan to attend a religious festival to honor the Sun god．
C．He thought the city of Chichen-Itza was quite different from the modern town of Cancun．
D．He was attracted by the ruined ancient buildings there and wanted to take some photos．
63．The underlined word"admonishing"in Paragraph 2 probably means"C"．
A．urging          B．forcing          C．warning         D．frightening
64．Which of the following best shows climbing the pyramid of EL Castillo is a difficult task？D
A．The steps are very high and it is much more scaring to climb to the top．
B．The climbing calls for courage and patience，and also takes a long time．
C．When tourist climb up to the top，there is no elevator to take them down．
D．The pyramid is high and steep，and climbing down is much more fearful．
65．From the last paragraph，we can infer that the writerB．
A．had a bad impression of the visit and decided to leave as soon as possible．
B．thought modernization could offer people comforts and conveniences．
C．got tired of the modern life and tried a different one in his own way．
D．enjoyed himself in the climb though it was very tiring and dangerous．
5．While I was in 9 th grade，I built a circuit （电路装置） for the traffic system of our city．After getting the first prize．I got this valuable advice from my father；"Do whatever interests you，and don't let the work challenge you，make sure you are challenging that work．"
I have always preferred the projects which are challenging and related to real life problems．I clearly remember building a shipping program several years ago．I divided the whole project into several small sections．When I understood it clearly，used my brainstorming skill on it，and gave some basic ideas．Then I asked my professor for help before jumping into coding （编码）．At first，I did not know how to ask questions correctly and always asked the question"How do I do it？"As I  kept working and discussed with my professor，I became more comfortable and those"how"questions soon turned into"what if I do this and that"types of questions．
It took me four days to write the code．The desire to solve the problem kept me sleepless all nights brainstorming in even greater details．Every time I saw my program running smoothly，I exploded with joy．I still remember the last day of my work．I was getting some problem and didn't know what to do．At that moment，a man came in to clean．He has headphones，and he was dancing while cleaning the room．Seeing this，I burst out laughing．That moment calmed me．I regained energy and interest and started to work again，and soon I fixed the problem．
My success in the project proved that breaking up a large problem into small parts could help find a possible solution．Discussing the problem with others was also very beneficial．Now I have gained the confidence to attempt any kind of project．

2．Michelle Obama made a daring decision to return to the same designer who created her Inaugural（就职）Ball dress four years ago---and the risk paid off．
The First Lady looked extremely attractive in a red dress by designer Jason Wu．She teamed the dramatic dress with heels by Jimmy Choo and a diamond ring by Kimberly McDonald．
She surprised the fashion world by returning to a Wu design which had been made for her．
Four years ago at her first Inauguration Ball，Michelle shone in a white，one-shouldered floor-length dress by the designer．
Wu，who was 26at the time and had only been working in fashion for three years，saw his career take off after the First Lady's surprise decision to wear one of his dresses．
He said at the time that he was unaware she had chosen the dress and had been watching at home on his couch and eating pizza when she appeared．
After her 2013decision，Wu told Women's Wear Daily："Mrs．Obama likes to keep her secrets．She fooled me again．"
Wu released a women's clothing and accessories（配饰）collection at Target last year and continues to be popular with the First Lady for official appointments．
The sleeveless dress with low-cut back flattered （突出）49-year-old Michelle's arms and neat waist．
It had been created especially for her by Wu and was a departure from the dark and plain color tone she stuck to at earlier inauguration events．

19．The baby monkey is much more developed at birth than the human baby．Almost from the moment it is born，the baby monkey can move around and hold tightly to its mother．During the first few days of its life the baby will approach and hold onto almost any large，warm，and soft object in its environment，particularly if that object also gives it milk．After a week or so，however，the baby monkey begins to avoid newcomers and focuses its attentions on"mother"-the real mother or the mother-substitute．
During the first two weeks of its life warmth is perhaps the most important psychological thing that a monkey mother has to give to its baby．The Harlows，a couple who are both psychologists，discovered this fact by offering baby monkeys a choice of two types of mother-substitutes-one covered with cloth and one made of bare wire．If the two artificial mothers were both the same temperature，the little monkeys always preferred the cloth mother．However，if the wire model was heated，while the cloth model was cool，for the first two weeks after birth the baby monkeys picked the warm wire mother-substitutes as their favorites．Thereafter they switched and spent most of their time on the more comfortable cloth mother．
Why is cloth preferable to bare wire？Something that the Harlows called contact  comfort seems to be the answer，and a most powerful influence it is．Baby monkeys spend much of their time rubbing against their mothers'skins，putting themselves in as close contact with the parent as they can．Whenever the young animal is frightened，disturbed，or annoyed，it typically rushes to its mother and rubs itself against her body．Wire doesn't"rub"as well as does soft cloth．Prolonged （长时间的）"contact comfort"with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk．
According to the Harlows，the basic quality of a baby's love for its mother is trust．If the baby is put into an unfamiliar playroom without its mother，the baby ignores the toys no matter how interesting they might be．It screams in terror and curls up into a furry little ball．If its cloth mother is now introduced into the playroom，the baby rushes to it and holds onto it for dear life．After a few minutes of contact comfort，it obviously begins to feel more secure．It then climbs down from the mother-substitute and begins to explore the toys，but often rushes back for a deep embrace as if to make sure that its mother is still there and that all is well．Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding onto its"mother．"
29．Psychologically，what does the baby monkey desire most during the first two
weeks of its life？A
A．Warmth                  B．Milk                 C．Contact               D．Trust
30．After the first two weeks of their life，baby monkeys prefer the cloth mother to
the wire mother because the former isD．

C．less frightening and less disturbing     D．more comfortable to rub against

A．it frequently rushes back for a deep embrace when exploring the toys
B．it spends more time screaming to get rewards
C．it is less attracted to the toys though they are interesting
D．it cares less about whether its mother is still around
32．The main purpose of the passage is toB．
A．give the reasons for the experiment
B．present the findings of the experiment
C．introduce the method of the experiment
