1 . Returning to a book you’ve read many times can feel like drinks with an old friend. There’s a welcome familiarity - but also sometimes a slight suspicion that time has changed you both, and thus the relationship. But books don’t change, people do. And that’s what makes the act of rereading so rich and transformative.

The beauty of rereading lies in the idea that our bond with the work is based on our present mental register. It’s true, the older I get, the more I feel time has wings. But with reading, it’s all about the present. It’s about the now and what one contributes to the now, because reading is a give and take between author and reader. Each has to pull their own weight.

There are three books I reread annually .The first, which I take to reading every spring is Emest Hemningway’s A Moveable Feast. Published in 1964, it’s his classic memoir of 1920s Paris. The language is almost intoxicating (令人陶醉的)，an aging writer looking back on an ambitious yet simpler time. Another is Annie Dillard’s Holy the Firm, her poetic 1975 ramble (随笔) about everything and nothing. The third book is Julio Cortazar’s Save Twilight: Selected Poems, because poetry. And because Cortazar.

While I tend to buy a lot of books, these three were given to me as gifs, which might add to the meaning I attach to them. But I imagine that, while money is indeed wonderful and necessary, rereading an author’s work is the highest currency a reader can pay them. The best books are the ones that open further as time passes. But remember, it’s you that has to grow and read and reread in order to better understand your friends.

2 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.

To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.

Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.

For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.

The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?

1. What is the recent study mainly about?

A．Food safety.	B．Movie viewership.
C．Consumer demand.	D．Eating behavior.

2. What does the underlined word “beanpoles” in paragraph 1 refer to?

A．Big eaters.	B．Overweight persons.

3. Why did the researchers hire the actor?

A．To see how she would affect the participants.

B．To test if the participants could recognize her.

C．To find out what she would do in the two tests.

D．To study why she could keep her weight down.

4. On what basis do we “adjust the influence” according to the last paragraph?

A．How hungry we are.	B．How slim we want to be.
C．How we perceive others.	D．How we feel about the food.

3 . When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).

Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.

Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.

Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.

The fur trade kept nutria in check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.

Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.

Then there’s Righteous Fur and its unusual fashion. Model Paige Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them-I think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She is trying to come up with a label to attach to nutria fashions to show it is eco-friendly.

1. What is the purpose of the fashion shows in New Orleans and Brooklyn?

A．To promote guilt-free fur.

B．To expand the fashion market.

A．Nutria damage the ecosystem seriously.

B．Nutria are an endangered species.

C．Nutria hurt local cat-sized animals.

D．Nutria are illegally hunted.

3. What does the underlined word “collapsed” in paragraph 5 probably mean?

A．Boomed.

B．Became mature.

C．Remained stable.

D．Crashed.

4. What can we infer about wearing fur in New York according to Morgan?

A．It’s formal.

B．It’s risky.

C．It’s harmful.

D．It’s traditional.

4 . For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.

Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.

To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men’s fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.

Then, on two separate morning visits to the scientists’ lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.

Just before and an hour after each workout, the scientists took additional samples of the men’s blood and fat tissue.

Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.

But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.

The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.

C．Lifestyle is not as important as morning exercise.

D．Physical exercise before breakfast is better for health.

5 . The end of the school year was in sight and spirits were high. I was back teaching after an absence of 15 years, dealing with the various kinds of "forbidden fruit" that come out of book bags. Now was the spring of the water pistol.

I decided to think up a method of dealing with forbidden fruit.

"Please bring that pistol to me," I said. "I'm going to put it in my Grandma's Box."

"What's that?" they asked.

"It's a large wooden chest full of toys for my grandchildren," I replied,

"You don't have grandchildren," someone said.

"I don't now." I replied. "But someday I will. When I do, my box will be full of wonderful things for them."

My imaginary Grandma's Box worked like magic that spring, and later. Sometimes. students would ask me to describe all the things I had in it. Then I would try to remember the different possessions I supposedly had taken away—since I seldom actually kept them. Usually the offender would appear at the end of the day, and I would return the belonging.

The-years went by, and my first grandchild Gordon was born. I shared my joy with that year's class. Then someone said, "Now you can use your Grandma's Box." From then on instead of coming to ask their possessions back, the students would say, "That's okay. Put it in your Grandma's Box for Gordon."

I loved talking about the imaginary box, not only with my students but also with my own children. They enjoyed hearing about all the forbidden fruit I had collected. Then one Christmas I received a surprise gift—a large, beautifully made wooden chest. My son Bruce had made my Grandma's Box a reality.

A．She enjoys telling jokes.	B．She is a strict and smart teacher.
C．She loves doing woodwork.	D．She is a responsible grandmother

6 . Certain forms of AI are indeed becoming ubiquitous. For example, algorithms (算法) carry out huge volumes of trading on our financial markets, self-driving cars are appearing on city streets, and our smartphones are translating from one language into another. These systems are sometimes faster and more perceptive than we humans are. But so far that is only true for the specific tasks for which the systems have been designed. That is something that some AI developers are now eager to change.

Some of today’s AI pioneers want to move on from today’s world of “weak” or “narrow” AI, to create “strong” or “full” AI, or what is often called artificial general intelligence (AGI). In some respects, today’s powerful computing machines already make our brains look weak. AGI could, its advocates say, work for us around the clock, and drawing on all available data, could suggest solutions to many problems. DM, a company focused on the development of AGI, has an ambition to “solve intelligence”. “If we’re successful,” their mission statement reads, “we believe this will be one of the most important and widely beneficial scientific advances ever made.”

Since the early days of AI, imagination has outpaced what is possible or even probable. In 1965, an imaginative mathematician called Irving Good predicted the eventual creation of an “ultra-intelligent machine…that can far surpass all the intellectual (智力的) activities of any man, however clever.” Good went on to suggest that “the first ultra-intelligent machine” could be “the last invention that man need ever make.”

Fears about the appearance of bad, powerful, man-made intelligent machines have been reinforced (强化) by many works of fiction — Mary Shelley’s Frankenstein and the Terminator film series, for example. But if AI does eventually prove to be our downfall, it is unlikely to be at the hands of human-shaped forms like these, with recognisably human motivations such as aggression (敌对行为). Instead, I agree with Oxford University philosopher Nick Bostrom, who believes that the heaviest risks from AGI do not come from a decision to turn against mankind but rather from a dogged pursuit of set objectives at the expense of everything else.

The promise and danger of true AGI are great. But all of today’s excited discussion about these possibilities presupposes the fact that we will be able to build these systems. And, having spoken to many of the world’s foremost AI researchers, I believe there is good reason to doubt that we will see AGI any time soon, if ever.

B．It will come into being soon.

C．It will be controlled by humans.

D．It may be more dangerous than ever.

7 . As more and more people speak the global languages of English, Chinese, Spanish, and Arabic, other languages are rapidly disappearing. In fact, half of the 6,000-7,000 languages spoken around the world today will likely die out by the next century, according to the United Nations Educational, Scientific, and Cultural Organization (UNESCO).
In an effort to prevent language loss, scholars from a number of organizations- UNESCO and National Geographic among them –have for many years been documenting dying languages and the cultures they reflect.
Mark Turin, a scientist at the Macmillan Center, Yale University, who specializes in the languages and oral traditions of the Himalayas, is following that tradition. His recently published book, A Grammar of Thangmi with an Ethnolinguistic Introduction to the Speakers and Their Culture, grows out of his experience living, looking and raising a family in a village in Nepal.
Documenting the Tangmi language and culture is just a starting point for Turin, who seeks to include other languages and oral traditions across the Himalayans reaches of India, Nepal, Bhutan, and China. But he is not content to simply record these voices before they disappear without record.
At the University of Cambridge Turin discovered a wealth of important materials- including photographs, films, tap recordings, and field notes- which had remained unstudied and were badly in need of care and protection.
Now, through the two organizations that he has founded-the Digital Himalaya Project and the World Oral Literature Project- Turin has started a campaign to make such documents, found in libraries and stores around the world, available not just to scholars but to the youngers.
Generations of communities from whom the materials were originally collected.Thanks to digital technology and the widely available Internet. Turin notes, the endangered languages can be saved and reconnected with speech communities.
1. Many scholars are making efforts to ________.

A．promote global languages

A．The cultural statics in India.

B．The documents available at Yale.

C．His language research in Britain.

D．His personal experience in Nepal.

4. Which of the following best describe Turin’s Work?

A．Write sell and donate.

B．Record, repeat and reward.

C．Collect, protect and reconnect.

D．Design, experiment and report.

8 . If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.

The scientists studied the genes of thousands of people between the ages of 16 and 102.The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health.

It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it’s worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure.

Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance. He said Sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren’t found guilty.

Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip (时髦的). However, that hasn’t stopped many celebrities from happily wearing glasses even if they do not need them. Justin Bieber is just one high-profile fan of fashion glasses.

B．Because it can mislead the witnesses.

C．Because it can highlight clients’ qualities.

D．Because it can prove the clients’ innocence.

4. What is the general attitude to those who wear glasses for fashion?

A．Positive.

B．Negative.

C．Mixed

D．Indifferent.

9 . To learn to think is to learn to question. Those who don't question never truly think for themselves. These are simple rules that have governed the advancement of science and human thought since the beginning of time. Advancements are made when thinkers question theories and introduce new ones. Unfortunately, it is often the great and respected thinkers who end up slowing the progress of human thought. Aristotle was a brilliant philosopher whose theories explained much of the natural world, often incorrectly. He was so esteemed by the scientific community that even 1，200 years after his death, scientists were still trying to build upon his mistakes rather than correct them!

Brilliant minds can intimidate up­and­coming thinkers who are not confident of their abilities. They often believe they are inferior to the minds of giants such as Aristotle, leading many to accept current paradigms instead of questioning them.

I, like many thinkers of the past, once believed in my mental inferiority. I was certain that my parents, my teachers-adults in general-were always right. They were like a textbook to me; I didn't question what was written on those pages. I respected them, and accepted whatever they told me. But that attitude soon changed. My mind's independence was first stimulated in the classroom.

A stern, 65­year­old elementary­school science teacher once told me that light is a type of wave. I confidently went through years of school believing that light is a wave. One day，however I heard the German exchange student mention that light could be made up of particles. As the others laughed at his statement, I started to question my beliefs.

Maybe the teachers and textbooks hadn't given me the whole story. I went to the library, did some research and learned of the light­as­a­wave versus light­as­a­particle debate. I read about Einstein's discovery of the dual nature of light and learned the facts of a paradox(悖论) that puzzles the world's greatest thinkers to this day. Light behaves as both a particle and a wave, it is both at once. I realized I had gone through life accepting only half of the story as the whole truth.

Each new year brought more new facts, and I formulated even more questions. I found myself in the library after school, trying to find my own answers to gain a more complete understanding of what I thought I already knew. I discovered that my parents and teachers are incredible tools in my quest for knowledge, but they are never the final word. Even textbooks can be challenged. I learned to question my sources, I learned to be a thinker. I once believed that everything I learned at home and at school was certain, but I have now discovered to re­examine when necessary.

Questions are said to be the path to knowledge and truth, and I plan to continue questioning. How many things do we know for sure today that we will question in the future? At this moment, I know that our sun will burn for another five billion years, and I know nothing can escape the gravity of a black hole. This knowledge, however, may change in the next 20 years-maybe even in the next two. The one thing we can control now is our openness to discovery. Questions are the tools of open minds, and open minds are the key to intellectual advancement.

10 . The outstanding biography — from the same author who brought us Steve Jobs and Einstein — portrays the life of the complicated Renaissance (文艺复兴时期的) artist with details. We come to see da Vinci as not only an inventor of musical instruments and early flying machines, but also a notebook keeper and vegetarian (素食者), who had trouble finishing many of the projects and paintings he started.

Yet what is most thrilling is getting to know da Vinci the scientist. Isaacson explains how loving science and applying the scientific method to observing the world was really what made da Vinci a great artist and, Isaacson argues, a genius.

Da Vinci was fascinated with observing and understanding phenomena in nature, from the proportions of the human body to how the muscles of the lips moved. He wanted to know about everything around him, in minute detail, Isaacson writes. He wondered about questions “most people over the age of ten no longer puzzle about”— for instance, how the tongue of a woodpecker works.

To learn about the world, da Vinci combined his own observations with experimentation. Never formally schooled, “he preferred to induce from experiments rather than deduce from theoretical principles,” Isaacson explains. He recorded his observations, looked for patterns among them, and then tested those patterns through additional observation and experimentation.

“When he became fascinated with the idea that he could invent flying machines, three and a half centuries before the Wright brothers flew the first airplane, he observed various birds and filled notebooks with the function and speed at which their wings flapped. That’s why lsaacson calls da Vinci an exemplar of this scientific method.” He goes on: “Galileo, born 112 years after Leonardo, is usually credited with being the first to develop this kind of approach and is often regarded as the father of modern science,” the historian Fritjof Capra wrote. “There can be no doubt that this honor would have been bestowed (赐予) on Leonardo da Vinci had he published his scientific writings during his lifetime, or had his notebooks been widely studied soon after his death.”

Da Vinci’s emphasis on empirical observation also helped him improve his art. First, he was able to use what he learned from looking at nature to paint and draw. His studies of the body, animals, motion, shadow and light, perspective and proportion helped him better understand what he was seeing in front of him, and render it in art more accurately and finely than anyone else of his time. He also used his observations of nature to make connections among phenomena. A recorder (竖笛) was like a larynx (喉管) in the throat. Here’s Isaacson again: What Leonardo probably began as four distinct elements ended up woven together in a way that illustrates a fundamental theme in his art and science: the interconnectedness of nature, the unity of its patterns, and the similarity between the workings of the human body and those of the earth.

Most importantly, his curiosity-driven explorations, and ability to connect art and science, helped him innovate in his work. They helped him think differently, Isaacson argues. Da Vinci made surprisingly diverse series of discoveries, including conceptualizing the helicopter and solar power and advancing knowledge about everything from the reproductive organs to botany. This genius is also what drew lsaacson to Albert Einstein and Steve Jobs as subjects: They’re all innovators who were inspired by and drew connections between art and science.

“Leonardo da Vinci is the ultimate example of the main theme of my previous biographies: how the ability to make connections across disciplines — arts and sciences, humanities and technology — is a key to innovation, imagination, and genius,” Isaacson writes. And this wonderful book is a reminder, in a time of increasingly narrow specialization and focus, that the methods of Renaissance men like da Vinci are as relevant as ever.
