    A farm planted levels or floors is called a vertical(垂直的)farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards，rather than outwards，it requires much less space than a conventional farm.
    The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18­story vertical farm could feed as many as 50,000 people，all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time，food would be delivered in fresher condition and with less damage.
    There is a growing concern about the use of pesticides(杀虫剂) in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space，therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics(水耕法) could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course，not all food does well with this type of planting，but there are many crops that actually seem to do better.
    In some climates，a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words，we could grow crops in areas where we never could before.
    Vertical farms may just be a concept for now，but they are a concept that will solve many of our problems in the future.
    小题1:According to the passage, a vertical farm ________.
    A．is mainly built outwards
    B．is dependent on solar power
    C．is planted on levels upwards
    D．is only an environmental friendly farm
    小题2:Compared to the conventional farm, the vertical farm can ________.
    A．depend far less on sunlight
    B．greatly increase the use of soil
    C．help to protect the limited gardens
    D．reduce the harmful effect of pesticides
    小题3: It can be learned from the passage that vertical farms ________.
    A．have already been put into use
    B．only use hydroponics to grow food
    C．need less room than conventional farms
    D．may increase the transportation costs
    小题4:What would be the best title for the passage?
    A．Vertical farms for our future
    B．Ways to deal with future problems
    C．Vertical farms and green skyscrapers
    D．Making full use of our limited land

    小题1:C
    小题2:D
    小题3:C
    小题4:A

    You put a great deal of effort into reaching the college of your choice. It’s time to get started. But what’s next? Beginning college can be an exciting but awkward time. Follow these tips to adjust to your new life rapidly and make the most of your college experience.
    ● To save time and money, use the college’s bus system. Taking the bus to school is quick, easy and free in most college towns. You won’t have to locate or afford a place to park either. It’s also a good way to be environmentally aware.
    ● Save pennies on books by waiting until class starts. You might not even need all of the recommended books. New textbooks cost an arm and a leg. Try buying used textbooks — it’s a surefire way to save money and serves the purpose as well.
    ● Do never look at college life as an endless series of parties and social activities. But there is a whole lot more to college if you’re serious about graduating. Having a good college experience is all about balancing work and fun.
    ● Be aware that your living environment can largely affect your academic success. If the dorm doesn’t suit you, consider living at home with your family or renting your own apartment. The best location for your studies isn’t always your dorm. Find a quiet area, like the library, to do your work. Alternatively, buy some headphones that block out noise.
    ● Be mindful of your diet. Make healthy food choices and watch what you eat. Avoid foods that are processed or high in sugar. The “freshman 15” is real. Many college students gain at least 15 pounds during their freshmen year.
    ● While electives (选修课) can be helpful when figuring out your major, you shouldn’t entirely rely on them. Clubs and other organizations exist around. Get involved. Make sure, though, that you still have time to study. Having too much on your plate can hurt your grades.
    小题1:Which of the following ideas can be financially wise? 
    A．Driving your own car.B．Buying used books.
    C．Renting an apartment.D．Attending activities.
    小题2:In the text, freshmen are repeatedly warned against ______.
    A．academic failuresB．physical problems
    C．traffic accidentsD．social activities
    小题3:The “freshman 15” tells the fact that some freshmen ______.
    A．attend limited activities on campus
    B．have little regular physical exercise
    C．focus less on their academic work
    D．take relaxed attitudes to their diets
    小题4: The underlined phrase “having too much on your plate” probably refers to ______.
    A．using too much money for meals
    B．eating too many unhealthy foods
    C．taking part in too many after-class activities
    D．taking an elective that has too many students

    Apologizing is both an Art and a Science. The Art lies in the manner in which the apology is delivered while the Science is the recipe that forms the apology itself. A proper apology should always include several ingredients. Now let’s take a closer look at these ingredients.
    Give a detailed account of the offense, and make sure both you and the other person are talking about the same thing. Whether you make it in secret or public doesn’t matter, but your apology should be focused on the particular event.
    Next, by acknowledging the hurt or damage done, you are making the recipient (接受者) begin to sense that you understand the situation. It is important to rebuild your relationship because it makes them feel their anger is understandable.
    Don’t try to defend yourself by offering any excuses, which is important to let them know that you understand the event and you actions do cause them harm. The apology is all about THEM and how they feel. It doesn’t matter if the actions were intentional or not, the end result is the same and that is what needs to be focused on when learning how to say, “I’m sorry”.
    Give a sincere statement of regret such as “I apologize” or “I’m sorry”. Above all, tell them it won’t happen again. After all, there is no value in apologizing for something that you will do again and again.
    Finally, asking for forgiveness at the end of the apology gives the power back to the recipient. It tells them, that you have done all that you can do by apologizing and providing whatever form of restitution(补偿)you can. The next move is up to them.
    By including all these ingredients and applying them to your situation, you will know exactly how to say “I’m sorry” next time you need to.
    小题1:The passage mainly tells readers ____.
    A．the importance of apologizing
    B．the process of apologizing

    If you do not use your arms or your legs for some time, they will become weak; and when you start using them again, they will slowly become strong again.       knows this, but nobody would think of     the fact.
    Yet there are many people who        to know that the memory works in the same way. When someone says that       has a good memory, he       means that he keeps his memory in practice     exercising it very     , either consciously or unconsciously. When someone else says that his memory is     , he means that he does not give it enough      to become strong. The position is exactly the same as that of       people, one of      exercises his arms and legs by playing ball, while the other       in a chair or a car all day. If a friend of yours says that his arms are weak, we know that it is his own      , But if he tells us that he has a poor memory,      of us think that his parents are to blame, or that he is just     , and few of us realize that it is just as it was his arms or legs that were weak. Not all of us can become very strong in body or very clever in mind,       all of us can improve our strength and our memory by the same means that      .
    Have you ever       that people who cannot read or write usually have      memories than those who can? Why is this? Of course, because they cannot write down something in a little notebook or something else. They have to remember names, places, songs and stories; so their memory is always being exercised.
    In a word, if you want to have a good memory, do practice       things。

    Mark and his brother Jason both were looking at the shining new computer enviously, Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
    “Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
    “He won’t find out,” Mark said. “I’ll just have a quick look and shut it down.”
    Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
    It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.” “Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen: “ENTER NAMES
    VOYAGER 1:…
    VOYAGER 2:…”
    Mark’s fingers flew across the keyboard as he typed in both of their names.
    “INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED (自动回收程序已启动).”
    The screen turned even brighter and a noise suddenly rose in volume.
    “I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
    But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒) , until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.
    “TRANSPORT SUCCESSFUL. DESTINATION (目的地)：MARS. RETRIEVE DATE: 2025.”
    小题1:Why did Mark touch the computer against his father’s warning?
    A．He wanted to take a voyage. B．He wanted to practice his skill.

    It is often said that man has become the enemy of our planet. This is no exaggeration(夸张), for reports show that man’s greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man’s industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before.
    Of course, this is not just because of man’s greed—it is man’s pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man’s immediate needs.
    Perhaps unknowingly，man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer—a protective layer in the atmosphere that protects us against the harmful effects of the sun’s ultraviolet (紫外线)rays. In fact, documented reports have shown a terrible fact that there are “holes” in the ozone layer over the Antarctic. And they appear to be expanding.
    Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals.
    There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an “I-don’t-care” attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale（规模）is greatly needed, so that all countries, great and small—the “haves” and the “have nots”—may realize their responsibilities for our planet.
    In the meantime, the UNEP seems to have taken steps in the right direction, and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth.
    小题1:Which of the following is a reason for the cutting and burning of forests?
    A．To build houses for more population. B．To have land for agriculture.
    C．To export trees to other countries.D．To build industrial plants.
    小题2:The holes in the ozone layer are largely due to________.
    A．man’s research activities B．the greenhouse effect
    C．the ultraviolent D．harmful chemicals
    小题3:Why don’t some countries care about the problem of the environment?
    A．They don’t want to put their lives in danger.
    B．They just don’t know how to solve the problem.
    C．They haven’t realized the seriousness of the problem.
    D．They don’t want to break their international commitment.
    小题4:66. What is the author’s attitude towards the future of the environment?
    A．Hopeful. B．Unconcerned C．Doubtful D．Objective

    Have you ever wondered why birds sing? Maybe you thought that they were just happy．After all, you probably sing when you are happy．
    Some scientists believe that birds do sing some of the time just because they are happy．However they sing most of the time for a very different reason．Their singing is actually a warning to other birds to stay out of their territory．
    Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims (声称) as its own．Only he and his family are welcome there． No other families of the same species are welcome．Your house is your territory where only your family and friends are welcome．If a stranger should enter your territory and threaten you, you might shout．Probably this would be enough to frighten him away．
    If so, you have actually frightened the stranger away without having to fight him．A bird does the same thing．But he expects an outsider almost any time, especially at nesting (筑巢) season．So he is screaming all the time, whether he can see an outsider or not．This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away．
    小题1:Some scientists believe that most of the time bird’s singing is actually ______．
    A．an expression of happinessB．a way of warning
    C．an expression of angerD．a way of greeting
    小题2:What is a bird’s “territory”?
    A．A place where families of other species are not accepted.
    B．A place where a bird may shout at the top of its voice．
    C．An area for which birds fight against each other．
    D．An area which a bird considers to be its own．
    小题3:Why do birds keep on singing at nesting season?
    A．Because they want to invite more friends．
    B．Because their singing helps frighten outsiders away．
    C．Because they want to find outsiders around．
    D．Because their singing helps get rid of their fears．
    小题4:How does the writer explain birds’ singing?
    A．By comparing birds with human beings．
    B．By reporting experiment results．
    C．By describing birds’ daily life．
    D．By telling a bird’s story．

    Cast your mind back to the past twenty years and hardly did anyone have their own email account. The Internet had just taken off in 1991 and people were only using office and PC­based email exchanges.
    In the mid 1990s external email providers appeared. The most famous of these was Hotmail, the first free email provider and web­based email service. Sabeer Bhatia and Jack Smith launched Hotmail on July 4, 1996. And Microsoft took note of and bought Hotmail for $400 million on December 30, 1997, a nice birthday present for Bhatia who turned 29 that day. It was relaunched as MSN Hotmail and in 2007 was relaunched again as Windows Live Hotmail.
    Fast forward the present day and most of us have at least a personal web­based email account. It seems impossible to live without them. One of the biggest advantages of email is the fact that communication has become so much easier, especially with those across different time zones. Email takes seconds to send a message whereas letters, as we used to communicate by, could take weeks. Of course there was the fax, that beeping invention from the 1980s, but it wasn’t as secure as email and you never knew if the person on the other end had picked up your fax or if it had got lost somewhere in the office.
    In conclusion, one of the best inventions from the 1990s has to be email. But sometimes people are too closely connected to their email and have a compulsion to check it several times a day. At work, people have become lazy and instead of going to speak to the person sitting next to them, they send an email，causing an in box to pile up with more time spent reading email and responding rather than working. Clearly, an invention that saved time because of its quick and speedy connection can now also cause us to waste a lot of time.
    小题1:The earliest web-based email came into being probably _______.
    A．in 1991B．in 1996C．in 1997D．in 2007
    小题2:The author mentions “fax” in the third paragraph in order to tell us that _______.
    A．it is exactly as good as email
    B．it is much better than email
    C．it is less convenient than email
    D．it is easier and faster than email
    小题3:The underlined word “compulsion” in Paragraph 4 probably means “_______”.
    A．strong desireB．common senseC．special curiosityD．general idea
    小题4:Which is the main idea of the last paragraph?
    A．We should check email boxes frequently.
    B．Lazy people like sending an email.
    C．Email brings us great convenience.
    D．Good inventions also cause problems.
