题目内容

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

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?

D．The episode airing in 1961 was the most entertaining of the TV science-fiction series.

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.

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.

People in cities all over the world shop in supermarkets. Who decides what you buy in the supermarket? Do you decide? Does the supermarket decide?
When you enter the supermarket, you see shelves full of food. You walk in the aisles (走道) between the shelves. You push a shopping cart and put your food in it.
You probably hear soft, slow music as you walk along the aisles. This may be an attempt to please you, so you will enjoy shopping. Some supermarkets want to increase their profits by playing soft and slow music, because the slow music makes you walk slowly and you have more time to buy things.
Fresh fruit and vegetables are usually put near the entrance. When you arrive at the supermarket, you think about the kinds of fruit and vegetables you need first. Once you’ve got that out of the way, you can relax and do the rest of the shopping without any hurry. Besides, if you see fresh goods first, it gives you a “feel good” impression of freshness, so you can not help spending your money.
Maybe you go to the meat department then. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk past all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.
Most of the food in supermarkets is very attractive. It all says “Buy me quickly!” to the customers. The fresh fruit and vegetables say “Buy me quickly!” as you walk by. The expensive meat says “Buy me quickly!” The supermarket tells you what to buy.
【小题1】Some supermarkets play soft, slow music because it ______.

A．makes customers walk slowly and buy more

C．can make customers relaxed and happy

D．can tell customers exactly where to go

【小题2】The manager knows ______.

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.

Police fired tear gas and arrested more than 5,000 passively resisting protestors Friday in an attempt to break up the largest antinuclear demonstration ever staged in the United States. More than 135,000 demonstrators confronted police on the construction site of a 1,000-megawatt nuclear power plant scheduled to provide power to most of southern New Hampshire. Organizers of the huge demonstration said, the protest was continuing despite the police actions. More demonstrators were arriving to keep up the pressure on state authorities to cancel the project. The demonstrator had charged that the project was unsafe in the densely populated area, would create thermal pollution in the bay, and had no acceptable means for disposing of its radioactive wasters. The demonstrations would go on until the jails and the courts were so overloaded that the state judicial system would collapse.
Governor Stanforth Thumper insisted that there would be no reconsideration of the power project and no delay in its construction set for completion in three years. “This project will begin on time and the people of this state will begin to receive its benefits on schedule. Those who break the law in misguided attempts to sabotage the project will be dealt with according to the law,” he said. And police called in reinforcements from all over the state to handle the disturbances.
The protests began before dawn Friday when several thousand demonstrators broke through police lines around the cordoned-off construction site. They carried placards that read “No Nukes is Good Nukes,” “Sunpower, Not Nuclear Power,” and “Stop Private Profits from Public Peril.” They defied police order to move from the area. Tear gas canisters fired by police failed to dislodge the protestors who had come prepared with their own gas masks or facecloths. Finally gas-masked and helmeted police charged into the crowd to drag off the demonstrators one by one. The protestors did not resist police, but refused to walk away under their own power. Those arrested would be charged with unlawful assembly, trespassing, and disturbing the peace.
【小题1】What were the demonstrators protesting about?
[A] Private profits.
[B]Nuclear Power Station.
[C] The project of nuclear power construction.
[D] Public peril.

Plants may not have eyes and ears，but they can recognize their siblings (兄弟姐妹)，and researchers at the University of Delaware have discovered how.The ID system lies in the roots and the chemical signals they secrete (分泌)．
Canadian researchers published that sea rocket，a common seashore plant，can recognize its siblings.Susan Dudley observed that when siblings are grown next to each other in the soil，they “play nice” and don’t send out more roots to compete.However，the moment one of the plants is thrown in with strangers，it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil.
After reading Dudley’s study，Bais decided to find the method behind the sibling recognition.Working in his laboratory，Bais and his doctoral student Meredith Biedrzycki set up a study with wild populations of Arabidopsis thaliana.In a series of experiments，young seedlings were exposed to liquid media containing the root secretions from siblings，from strangers，or only their own secretions.The length of the longest lateral (侧面的) root was measured.The exposure of plants to the root secretions of strangers induced (引诱) greater lateral root formation than exposure of plants to sibling secretions.Strangers planted next to each other are often shorter，because so much of their energy is directed at root growth.Because siblings aren’t competing against each other，their roots are often much shallower (浅的)．
Biedrzycki did the painstaking laboratory research，observing more than 3,000 plants involved in the study every day for seven continuous days and documenting the root patterns.“Arabidopsis roots are nearly translucent (半透明的) when they are young and were also twisted when I removed them from plates，”Biedrzycki notes.“This manuscript (手稿) is very important for my research since the focus of my thesis project is understanding the biochemical ways behind root secretions.”
The research also may have implications for the home gardener.“Often we’ll put plants in the ground next to each other and when they don’t do well，we blame the local garden center where we bought them or we attribute their failure to a germ，”Bais says.“But maybe there’s more to it than that.”
