    Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn’t the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of“virtual water（虚拟水）”.
    We typically think about water as the liquid that flows from a tap. However,92％of the water used by people goes into growing crops，according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world.
    For example．consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater—about 95％—is used to grow and process the ingredients(原料).Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．
    According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East, get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.   
    In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products

    I recently ran into a friend I hadn't seen for a long while.  Our conversation was lively andfull of news from both sides.  Before we parted she said  "You'll have to drop in sometime. "immediately  sensed that if I  simply  " dropped in"  I would take my friend by  surprise, and  I would be discouraged by the image of her standing in her doorway, staring at me, and asking, " Oh ,err …what brings you here?"
    Whatever happened to the unannounced drop-in visit? When I was growing up in the 1960s, it seemed that people-mostly relatives,  but also friends-were always dropping in .  My parents would put coffee on, and my mom would find something in the kitchen to serve along with it. Then the conversation would begin…The neighbor lady, a worrier, was unloading her sadness while my mom quietly listened. The Irish man next door had such an atcent that I remember asking what language he spoke. My Polish relatives arrived in packs…But I never heard my parents say any- thing like  " We  weren't expecting you"  or  " This  isn't a good  time.  " Drop-in  visitors  had  a certain right of way and became No. 1.
    What happened to such visits? Actually I know the answer. Times have changed. Everybody gets busy with work. There is no longer a stay-at-home mom keeping a pot of hot coffee or tea ready throughout the day for a surprise guest. Exploding malls and stores are now replacing homes as a central form of entertainment.
    Just the other day a former student of mine showed up.  "I'm sorry for the surprise visit. " my student began.  "I just wanted to see if you still lived here.  I'll only stay a minute. "
    My response was immediate.  "No, you won't," I said.  " Just come in, sit, have coffee, and we'11 talk. "I had nothing in the kitchen but we ordered pizza.  And we had a lovely time.  I have tried to keep the drop-in tradition alive though it takes some effort.

    Mothers and daughters go through so much—yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother，Sheila Solomon Klass，both gifted professional writers，prove to be ideal co­writers as they examine their decades of motherhood，daughterhood，and the wonderful ways their lives have overlapped(重叠)．
    Perri notes with amazement how closely her own life has mirrored her mother’s: both have full­time careers; both have published books，articles，and stories; each has three children; they both love to read.They also love to travel—in fact，they often take trips together.But in truth，the harder they look at their lives，the more they acknowledge their big differences in circumstance and basic nature.
    A child of the Depression(大萧条)，Sheila was raised in Brooklyn by parents who considered education a luxury for girls.Starting with her college education，she has fought for everything she’s ever accomplished.Perri，on the other hand，grew up privileged in the New Jersey suburbs of the 1960s and 1970s.For Sheila，wasting time or money is a crime，and luxury is unthinkable while Perri enjoys the occasional small luxury，but has not been successful at trying to persuade her mother into enjoying even the tiniest thing she likes.

    Looking deep into the lives they have lived separately and together，Perri and Sheila tell their mother­daughter story with honesty，humor，enthusiasm，and admiration for each other.A written account in two voices，Every Mother Is a Daughter is a duet(二重奏) that produces a deep，strong sound with the experiences that all mothers and daughters will recognize.       (2013·湖北，B)

    Picture a library without books? Well, I can’t. Ever since I was little I would go to the library and take out numerous books. From picture books to beginning chapter books to YA books, books have always been a part of my life. Unlike many people today, I don't own a Kindle or a Nook or any type of e-reader. I prefer the old-fashioned book. There is something about holding a book and being able to turn the pages that I find comforting. In today's 21st century, books may become obsolete. For me that's something I find scary.
    I am a fan of the old TV science-fiction series Twilight Zone. One episode（一段情节）is about a librarian who has become obsolete. Though this episode aired in 1961, the writer of the series, Rod Serling was exactly on point when it came to predicting the future.
    In fact, in San Antonio, Texas the first-ever bookless library in the country opened. The library is full of iMacs, tablets and iPads which cost a huge $2. 3 million. The library offers around 10,000 e-books. So the question is, is this what the future will soon be? Mary Graham, vice president of South Carolina's Charleston Metro Chamber of Commerce states, "This is the future…If you're going to be building new library facilities, this is what you need to be doing."
    It is our generation that will be the guinea pigs（试验品）of increasing technology like this. Is this a good or bad thing? Well, digital libraries may help the environment by not using paper; however, I feel like something will always be lacking with a digital book. A digital library is just the beginning.
    With all of this new technology, people seem to be more absorbed in their own world. One of my biggest complaints is when I am with my friends and they can't seem to get off their smart phone and talk to me. To make plans with a friend and then have them stuck on their phone the whole time is extremely rude. Not only is it disrespectful, but it reflects the direction of where human interactions are heading. Though social media is great, it also is addicting and has negative effects.
    Often when I go on Facebook it just makes me feel worse about myself. I'll see many of my 800 Facebook friends showing off their newest accomplishment or acceptance to college. Additionally, our society is becoming increasingly lazy. For instance, instead of doing mental math, people use their phone to solve 89 + 74. It is simple tasks like these that are allowing people to lack important educational and social skills.
    It is up to us to find a balance between technology and human values and interactions. With new technology being created every day, we need to learn how to use it alongside our great minds. After all, inventions are supposed to benefit society not harm it. In the day of technology, who knows what's next?
    小题1:The underlined word "obsolete" （Paragraph l）is closest in meaning to     .
    A．outdatedB．complexC．expensive D．meaningless
    小题2:What can we infer from the underlined sentence in Paragraph 2_______?
    A．The episode still enjoys great popularity nowadays.
    B．Rod Serling liked making predictions about the future.
    C．The situation of books today is similar to what Rod Serling predicted in the episode.
    D．The episode airing in 1961 was the most entertaining of the TV science-fiction series.
    小题3:What can we learn about the library in San Antonio, Texas?
    A．It is the first-ever library in America.
    B．It is of no practical use although it costs so much.
    C．It holds an exhibition of much electronic equipment.
    D．People can read e-books there with the help of the new facilities.
    小题4:Which of the following will the writer probably disagree with_______?
    A．Great as social media is, it does have some negative effects.
    B．With the increasing use of social media, something will actually be lost.
    C．Through social media, people can develop educational and social skills around.
    D．As a result of social media, people may communicate less with the people around.
    小题5:The tone of the passage is best described as       .
    A．OptimisticB．SkepticalC．SupportiveD．Objective

    For many centuries，countless scholars have asked the question：What is beauty? As designers update the latest fashions and artists create their masterpieces, what is considered beautiful changes at an alarming pace.
    Fifty years ago，the full-figured Marilyn Monroe was a symbol of the American aesthetic(美学的)value；today，many Hollywood actresses different in appearance from Marilyn’s have taken her place. However，aesthetic values not only differ from generation to generation，but do so along cultural lines as well. Often, what is considered disgusting to one civilization is just the aesthetic appeal in another. Thus it is difficult to give an absolute definition(定义)of beauty.
    As fundamental(基础的)physicists，my colleagues and I like to believe that we are involved in a search for a beauty that affects definition. The beauty that we search for is not what is set up through the work of people and subject to the tastes, but rather what has been laid down by nature Physics allows its students to look past outer appearances，into a deeper beauty. As a human being，I am attracted by the visual appeal of a wave crashing on the beach. As a physicist, however I am able to see the deeper beauty of the physical laws that govern such a phenomenon.
    In truth，since Albert Einstein put forward the idea that there might be one main physical theory that governs the universe，aesthetics have become a driving force in modern physics. Einstein and other later physicists have discovered that：Nature, as its most fundamental level，is beautifully constructed. The extraordinary simplicity of the laws that govern the universe is really breathtaking . As Einstein said, it would seem more likely that we should find ourselves living in a“chaotic(无秩序曲)world，in no way graspable through thinking”. Yet we are now closer than ever to a full understanding of the universe’s beautiful clockwork. As new discoveries and technologies allow us to examine the physical world on deeper and deeper levels，we find that the beauty itself becomes much deeper.
    小题1:The reference to“Marilyn Monroe”in Paragraph 2 mainly serves to___________.
    A．provide an example of today’s beauty standards
    B．show there is no fixed definition of aesthetics
    C．compare traditions of the East to the West
    D．discuss her abilities as an actress
    小题2:When appreciating a wave crashing on the beach，a physicist sees the beauty of___________.
    A．the visual attractionB．the powerful sounds
    C．the physical laws behindD．the lovely creatures
    小题3:Why are Albert Einstein’s words mentioned in Paragraph 3?
    A．To detail the functions of physical laws.
    B．To highlight the range of Einstein’s influence.
    C．To show that Einstein doubted the beauty of physics.
    D．To stress the very simplicity of the laws of the universe.
    小题4:The passage is mainly to___________.
    A．present a special way of seeing beauty
    B．emphasize the influence of physics
    C．discuss the awareness of cross-culture
    D．argue the traditional ideas on value

    His ignorance was as remarkable as his knowledge. Of contemporary literature, philosophy and politics he appeared to know next to nothing. Upon my quoting Thomas Carlyle, he inquired in the naivest way who he might be and what he had done. My surprise reached a climax, however, when I found incidentally that he was ignorant of the Copernican Theory and of the composition of the Solar system.
    “You appear to be astonished, ” Holmes said, smiling at my expression. “Now that I do know it I shall do my best to forget it. You see, I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose: A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best jumbled up with a lot of other things, so that he has difficulty in laying his hand upon it. It is a mistake to think that the little room has elastic walls and can distend to any extent. Depend upon it, there comes a time when for every addition of knowledge you forget something that you know before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”
    “But the Solar System! ” I protested.
    “What the deuce is it to me?” he interrupted impatiently.
    One morning, I picked up a magazine from the table and attempted to while away the time with it, while my companion munched silently at his toast. One of the articles had a pencil mark at the heading, and I naturally began to run my eye through it.
    Its somewhat ambitious title was “The Book of Life, ” and it attempted to show how much an observant man might learn by an accurate and systematic examination of all that came in his way. It struck me as being a remarkable mixture of shrewdness and of absurdity. The reasoning was close and intense, but the deduction appeared to me to be far-fetched and exaggerated. The writer claimed by a momentary expression, a twitch of a muscle or a glance of an eye, to fathom a man’s inmost thought. Deceit, according to him, was impossibility in the case of one trained to observation and analysis. His conclusions were as infallible as so many propositions of Euclid. So startling would his results appear to the uninitiated that until they learned the processes by which he had arrived at them they might well consider him as a necromancer.
    “From a drop of water, ”said the writer, “a logician could infer the possibility of an Atlantic. So all life is a great chain, the nature of which is known whenever we are shown a single link of it. Like all other arts, the science of Deduction and Analysis is one which can be acquired by long and patient study, nor is life long enough to allow any mortal to attain the highest possible perfection in it. ”
    This smartly written piece of theory I could not accept until a succession of evidences justified it.
    小题1: What is the author’s attitude toward Holmes?
    [A]Praising.
    [B]Critical.
    [C]Ironical.
    [D]Distaste.
    小题2: What way did the author take to stick out Holmes’ uniqueness?
    [A]By deduction.
    [B]By explanation.
    [C]By contrast.
    [D]By analysis.
    小题3: What was the Holmes’ idea about knowledge-learning?
    [A]Learning what every body learned.
    [B]Learning what was useful to you.
    [C]Learning whatever you came across.
    [D]Learning what was different to you.
    小题4: What did the article mentioned in the passage talk about?
    [A]One may master the way of reasoning through observation.
    [B]One may become rather critical through observation and analysis.
    [C]One may become rather sharp through observation and analysis.
    [D]One may become practical through observation and analysis.

    Blind imitation (模仿)is self-destruction. To those who do not recognize their unique worth. Imitation appears attractive: to those who know their strength. Imitation is unacceptable.
    In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes (菜谱) and turned out some tasty dishes. But soon I grew bored. Why follow someone else’s way of cooking when I could create my own? Imitating role models is like using training wheels on a child’s bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.
    In daily life, imitation can hurt us if we subconsciously (下意识地) hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others.
    In the field of entertainment, our culture glorifies celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors.
    Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration, not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.
    Syudy your role models, accept the gifts they have given, and leave behind what does not server. Then you can say,” I stand on the shoulders of my ancestors” tragedies and tory, and know that they are cheering on.
    小题1: Imitation proves useful when you        .
    A．know you are unique
    B．lose the balance of life
    C．begin to learn something new
    D．get tired of routine practice
    小题2:  To avoid the bad result of imitation, we should________.
    A．forget daily fear and pain
    B．choose the right example
    C．ask others for decisions
    D．stay away from stars
    小题3:.Acording to the author. The world moves on because of those who are          .
    A．desperate to intruence others with their knowledge
    B．ready to turn their original ideas into reality
    C．eager to discover what their ancestors did
    D．willing to accept others’ ideas
    小题4: The trouble a creator faces is          .
    A．the lack of strong motivation
    B．the absence of practical ideas
    C．how to search for more materials
    D．how to use imagination creatively
    小题5: What is the author’s purpose in writing this passage?
    A．To highlight the importance of creatively.
    B．To criticize the characters of role models.
    C．To compare imitation with creation.
    D．To explain the meaning of success.

    With the crazy smog going on in China, businessmen are now ready to grope for your wallet. “Smog economy” is stimulating a shopping spree on certain products against the terrible weather. Now let’s see what we have on the list to help us through the crisis.
    1. Masks
    Well, I would say you had better stay indoors to save your lives. PM 2.5 just surged up to 750 in Beijing recently. 3M just sold 220,000 masks of a kind. No.1 best-selling products!
    2. Air purifiers
    This kind of products is rarely seen in Chinese households in the past. They have become a necessity now. I do like these little gadgets, but they are just too expensive.
    3. Oxygen inhalers
    I didn’t realize oxygen inhalers also get a cut in the smog economy. As a matter of fact, your oxygen uptake has nothing to with relieving (减轻) the impact of smog. It might even lead to oxygen poisoning when you inhale too much oxygen. So don’t get greedy.
    4. Salt lamps
    Compared to oxygen inhalers, salt lamps are even worse. Some stores are selling the products at several hundred yuan, saying that they can release negative ions(离子), reduce radiation levels and purify the air. The lamps mainly contain sodium chloride. The boiling point of sodium is about 800 degrees centigrade and that of candle is 500. So how on earth can negative ions be released at only 500 degrees?
    5. Plants that absorb smog
    Yeah, right. Plants Vs Smog. It is scientifically justified (证明) that some plants do absorb pollutants from the air. Money plants and calla lilies are among the best-sellers in the market. Even if they don’t work, it’s good to have some plants in the house anyway.
    小题1:According to the passage, smog _______.
    A．give some economic chances to businessmen
    B．is very bad to economy
    C．makes some crisis come out
    D．have nothing to do with the economy
