Why do you go to the library？For books，yes—but you like books because they tell stories.You hope to get lost in a story or be transported into someone else's life.At one type of library you can do just that—even though there's not a single book.
At a Human Library，instead of books，you can “borrow” people.People with unique life stories volunteer to be the “books.” For a certain amount of time，you can ask them questions and listen to their stories，which are as fascinating as any you can find in a book.(If you attend，be sure to review the habits that make you a good listener.) Many of the stories have to do with some kind of depressing topic.You can speak with a refugee，a soldier suffering from PTSD(创伤后遗症)，a homeless person and a woman living with HIV.The Human Library encourages people to take time to truly get to know and learn from someone they might otherwise make a snap judgement about.According to its website，the Human Library is “a place where difficult questions are expected，appreciated and answered.”
The Human Library Organization came to be in Copenhagen，Denmark in 2000.Romni Abergel and his colleagues hosted a four­day event during a major Northern European festival.After the success of this event，Abergel founded the Human Library Organization，hoping to raise awareness among youth about depression，which has been growing ever since.
Though there are a few permanent human libraries，most aren't places at all，but events.Though many do take place at physical libraries，you don't need a library card—anyone can come and be part of the experience.There have been human library events all over the globe，in universities and in pubs，from Chicago to Tunis to Edinburgh to San Antonio.Check out the organization's Facebook page to see when the Human Library might be arriving near you.
【语篇解读】　本文是一篇说明文。文章主要介绍了人类图书馆。在人类图书馆里，人们借的不是书本，而是“借”人。

A．True.　 B．Quick.
C．Wrong. D．Obvious.
B　[词义猜测题。根据第二段中的“The Human Library encourages people to take time to truly get to know and learn from someone they might otherwise make a snap judgement about.”可知， 人类图书馆鼓励人们花时间去真正了解和学习，否则他们可能会对某人做出仓促的判断。take time to为固定短语，表示“慢慢地做某事”。根据otherwise(否则的话)，表示前后两句是相反的，因此与“慢慢地做某事(take time )”的相反的则是快速的。分析选项可知B项(Quick快的)。]

Under the cold clear water of Lake Huron，researchers have found a five­and­a­half­foot­long piece of wood that is 8，900 years old.The wood，which is tapered (使成锥形) on one side in a way that looks deliberate，may provide important clues to a mysterious period in North American prehistory.
“This was the stage when humans gradually shifted from hunting large animals to fishing，gathering and agriculture，”said anthropologist John O'Shea.“But because most of the places in this area that prehistoric people lived in are now under water，we don't have good evidence of this important shift itself.We just have clues from before and after the change.”
With support from the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administration (NOAA)，O'Shea and his colleague Guy Meadows began exploring the area several years ago.In 2009 they reported finding a series of stone features that they believe were “drive lanes” used by ancient Indian hunters.
Since that discovery，O'Shea and Meadows have worked on identifying human campsites，which are typically located away from hunting areas.On their 25­foot boat，the researchers first spotted the ancient wood object using a small piece of equipment with a camera.Then a team of divers — including O'Shea — went down about 100 feet to get it.
The wood's age has now been fixed by means of carbon dating.It is currently undergoing more detailed analyses to determine whether there has been human modification，which visual examination suggests.“The first thing you notice is that it appears to have been shaped with a rounded base and a pointed tip，”O'Shea said.“It must have been created.It looks like it might have been used as a tent pole or a pole to hang meat.”
In addition to the wood，the researchers have collected many other samples from the bottom of the lake.O'Shea and his colleagues will need to wait for calmer weather before they can resume their search for evidence of human life under the great lake.
【语篇解读】　本文是一篇说明文。文中提及的考古学家们的新发现有望印证远古人类从游猎文明到农耕文明的转变。
8．During the mysterious period mentioned in the passage，the Lake Huron area ．
A．was deserted by ancient Indians
B．witnessed the start of agriculture
C．was taken up by large animals
D．began to be covered by water
B　[推理判断题。从第一、二段中的“...may provide important clues to a mysterious period in North American prehistory ...when humans gradually shifted from hunting large animals to fishing，gathering and agriculture”可知，B项正确。]
9．Which of the following statements is NOT true?
A．The findings of John O'Shea and his colleagues may prove a previous theory.
B．The effort that John O'Shea and Meadows made before 2010 was meaningless.
C．Some equipment was used to support the discovery.
D．John O'Shea and his colleagues didn't draw the final conclusion from visual examination.
B　[细节理解题。从第三段的“In 2009 they reported finding a series of stone features that they believe were ‘drive lanes’ used by ancient Indian hunters.”可知，John O'Shea和Meadows 之前的研究也是有成效的。]
10．What's the fourth paragraph mainly about?
A．How the wood was found.
B．Why the wood is important.
C．Preparations that were made for the discovery of the wood.
D．Conclusions the experts have made from the discovery of the wood.
A　[段落大意题。本段主要交代了 John O'Shea 和同事们从何时开始、使用何种方法找到了这块木头。]
11．What do we know about the future plan of John O'Shea and his colleagues?
A．They will explore another lake soon.
B．They will study the weather around Lake Huron.
C．They will have a long holiday before going back to work.
D．They will continue to explore Lake Huron.
D　[细节理解题。从最后一段的“O'Shea and his colleagues will need to wait for calmer weather before they can resume their search for evidence of human life under the great lake.”可知，D项正确。]

While we know that language first appeared among Homo sapiens (智人) somewhere thousands of years ago，the secret to how language evolved is still unknown，and mainstream theories fall into two distinctly different camps.
One widely held theory is that language came about as an evolutionary adaptation.That was where the idea of natural selection came into play，which was the belief that the specific physical features of a population made that population more likely to survive its environment，like the turtle and its shell.On one hand，humans needed to communicate with each other in order to hunt，farm and defend themselves successfully from the surrounding severe environment.Being able to communicate by using language gave the human species a distinct survival advantage.On the other hand，language was needed for social interaction，according to those who subscribed to the adaptation theory.
In their paper “Natural Language and Natural Selection，” researchers Steven Pinker and Paul Bloom theorized that a series of calls or gestures evolved over time into combinations，giving us complex communication，or language.As things became more complicated around them，humans needed a more complex system to convey information to one another.Early man saw a group of deer he wanted to hunt.He made a sound to his hunting partner that means “deer are nearby.” One day，a storm came in and the hunter noticed that thunder scared the deer away.As a result，the hunter went hungry until the storm passed.Over time，the same hunter also learned to recognize the warning signs for bad weather­dark skies and increased wind.Early man realized that when the sky darkened and the wind picked up，he needed to tell his hunting partner to speed up the pursuit of the deer.Therefore，he came up with a series of sounds that refer to both the deer and the bad weather.That series of sounds was the beginning of an evolutionary adaptation that eventually became language.
As humans learned more about how to best survive，they developed a need to convey these survival methods to their population.To be brief，that's the adaptation theory.
【语篇解读】　本文是一篇说明文。文章主要介绍了语言是如何进化的。
12．What is the text mainly about?
A．The evolution of language.
B．The paper on natural selection.
C．The differences between theories.
D．The introduction to human reproduction.
A　[主旨大意题。根据第一段“While we know that language first appeared among Homo sapiens somewhere thousands of years ago，the secret to how language evolved is still unknown，and mainstream theories fall into two distinctly different camps.”以及第二段中的“One widely held theory is that language came about as an evolutionary adaptation.”可知，本文主要介绍了语言是如何进化的。故选A项。]
13．Why are the turtle and its shell mentioned in Paragraph 2?
A．To show the mystery of nature.
B．To support the evolutionary adaptation.
C．To stress the advantage of the turtle's shell.
D．To encourage people to study natural selection.
B　[推理判断题。根据第二段第二句“That was where the idea of natural selection came into play，which was the belief that the specific physical features of a population made that population more likely to survive its environment，like the turtle and its shell.”可知，作者提到海龟和龟壳是为了支持本段的中心论点：语言是作为一种进化适应而产生的。故选B项。]
14．How does the author explain the adaptation theory in paragraph 3?
A．By comparing.
B．By listing data.
C．By carrying out a survey.
D．By giving an example.
D　[推理判断题。根据第三段中的“As things became more complicated around them，humans needed a more complex system to convey information to one another...Therefore，he came up with a series of sounds that refer to both the deer and the bad weather.”可知，作者描述一个打猎的场景来说明语言的进化论，即用举例的方式来说明适应理论。故选D项。]
15．What will the author most probably tell us next?
A．The exact place where humans came from.
B．The other theory of how language evolved.
C．The reasons why animals cannot form language.
D．The methods of humans' shaping non­verbal thinking.
B　[推理判断题。根据第一段可知，主流理论分为两个截然不同的阵营，再根据最后一段“As humans learned more about how to best survive，they developed a need to convey these survival methods to their population.To be brief，that's the adaptation theory.”可知，两个不同的阵营，作者列举了其中的一种。由此推知，作者接下来最可能会告诉我们另一个语言进化理论。故选B项。]

When the cold weather hits，swimming is probably an activity that's far from your mind. 16 ．Here are some reasons why swimming in winter is great!
Work your muscles
Every time you swim，it is like doing a mini­resistance workout.Each kick and pull works your muscles more than you might imagine，especially your arms，shoulders and gluteus—the muscles that are inactive all day when you're sitting at your desk.Swimming also works your abs(腹肌) and will reduce your waistline. 17 ．
Lift your spirits
Exercise gives off chemicals in your body called endorphins(内啡肽)．These cause a positive feeling into your body which makes you happy. 18 ．The repetition，movement and breathing can help you to relax and that's why swimming is also regarded as a relaxing exercise.
19
Swimming is one of the best activities you can do all year round which benefits your body and your mind.Swimming has been found to increase blood flow to the brain，which leads to more oxygen.That means you'll experience improved alertness，better memory and cognitive(认知的)function.
Meet new people
20 ．You can meet people from all walks of life when swimming.Have a chat in the lap pool，join a swimming club，or get involved in social water sports to get to know people in your community.Besides，the great thing about swimming is that you can do it—rain or shine.Although your backyard pool，the river，or beach cools down over winter，most inside swimming pools run heated pools year round，so you've got no excuse to stop swimming!
A．Good for your brain
B．Greatly beneficial to your body
C．These chemicals can control your thought and action
D．Swimming has been shown to reduce stress and tension
E．While swimming is an individual sport，it's also very social
F．So，along with building fitness，it is a wonderful full­body exercise
G．But swimming is one of the best activities everyone can undertake in winter

I remember the first time I 38. (drive) a car in traffic after getting my driver's license.I was very nervous in that heavy traffic—my driving style showed that I wasn't a very confident driver.Now I'm much more 39. (experience) as a driver.Though I still don't consider 40. (me) a perfect one，I'm much more confident behind the wheel than 41. I was when I started.
In general，it is useless to work hard for doing something 42. (perfect) when you do it for the first time.You are setting the bar so high that you just feel bad when you are 43. (able) to meet the level you have set.
Also，perfection is just another way 44. (delay)，so trying to be perfect is just 45. waste of time.You should work hard for excellence instead.
【语篇解读】　本文利用作者自己的经历来说明第一次做某事的时候不要追求完美，追求完美不仅会耽误事情，也会浪费时间。
36．doing　[考查非谓语动词。句意：第一次做某件事的时候是几乎不可能做到完美的。succeed in doing sth.成功做某事。]
37．Therefore/Thus　[考查副词。句意：因此，当你第一次做某事的时候，也就是你要放弃完美的时候。根据两个句子之间的关系可知，此处应是表示结果的副词，又因为空格后面的标点符号是逗号，故填Therefore或Thus。]
38．drove　[考查动词的时态。句意：“我”记得在“我”拿到驾照后第一次开车。句中的the first time引导的时间状语从句描述的是过去发生的事情，所以要用一般过去时，故填drove。]
39．experienced　[考查词性转换。句意：现在我开车熟练多了。分析句子结构可知，此处应是形容词作表语。]
40．myself　[考查代词。根据前面的主语I可知此处用反身代词。 ]

42．perfectly　[考查词性转换。修饰动词do用副词形式。]
43．unable　[考查形容词。句意：你设定的目标太高，以至于当你不能达到这一标准时，你会感到难过。根据句意可知，此处应该是表示否定的意思，所以要用able的反义词unable。]
44．to delay　[考查非谓语动词。句意：而且，完美是另外一种耽误时间的方式……。way 意为“方式，方法”时，后面常用不定式作定语。]
45．a　[考查冠词。句意：……所以，努力想要达到完美只是浪费时间。a waste of time浪费时间。]

阅读下面材料，根据其内容和所给段落开头语续写两段内容，使之构成一篇完整的短文。
Bales left the pavement of Base Road and stepped onto snow­covered Jewell Trail.She planned a six­hour hike through New Hampshire's Mount Washington State Park.She had packed for almost every emergency and intended to walk alone.
She'd checked the weather forecast posted by the Mount Washington Observatory before she left.Based on her experience，Bales knew that her hike was realistic.Besides，she had two emergency plans and extra layers of clothing to better adjust her body temperature as conditions changed.
The hike up the lower part of Jewell Trail was pleasant.Bales felt excited as she walked up into snowy paths.The sun shone through the trees and cast a shadow over her smiling face.Less than an hour later，loads of dark clouds had replaced the sunshine，and snow covered the surrounding trees.
She still smiled.However，the weather was showing its teeth.Bales added even more layers to shelter herself from the cold winds and thick fog.She made her way across the snow­covered ridge (山脊)toward Mount Washington and began to think about calling it a day.Suddenly，she noticed something：a single set of footprints in the snow ahead of her，which had been made by a pair of sneakers—typically not the type for hiking.
Meanwhile，Bales was getting colder，even though she was moving fast and generating some body heat.With strong gusts of wind screaming and attacking her back and left side，she decided to abandon her plan.The only thing，however，kept her on the trail was the sneaker tracks in the snow.
注意：1.续写词数应为150左右；
2．请按照如下格式作答。
Bales faced a dilemma about whether to follow the tracks or not.



Her searching now turned into rescuing the man.




【参考范文】
Bales faced a dilemma about whether to follow the tracks or not. If she chose to follow the tracks，she'd add time and risk to her hiking.But the tracks ahead suggested someone might be in danger.She couldn't let this go.She called out into the frozen fog，“Is anybody out there？Do you need help？” The strong winds carried her voice away.Then she walked cautiously in the direction of the tracks.She rounded a corner and spotted a man sitting motionlessly.
Her searching now turned into rescuing the man. She approached him instantly and found he was suffering from frostbite on his feet.Without any hesitation，she covered his body with warm clothes，and then poured him some sugary drink.The wind roared over and they would die soon if they didn't get out of there.She supported the man and inched along the trail.With great efforts，Bales managed to save the man's life.Exhausted，she felt that it was all worth it.
