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(***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.

The National Park Service in the United States will mark its one hundredth anniversary in 2016. As it nears its second century, the Park Service plans to increase its educational programs for students and teachers.
The plans include transportation support for one hundred thousand students each year to visit national parks to learn about nature and history. Yellowstone is believed to have been the world"s first national park when it was established in 1872. Other students will get a chance to see parks in faraway places through Skype and other online programs.
The National Park Service also works with partners to provide education. One of its partners is a nonprofit organization called NatureBridge. NatureBridge is celebrating its fortieth anniversary and says one million young people have taken part in its programs. The organization works with students from kindergarten through twelfth grade and uses national parks as its classrooms. It provides field science programs at Yosemite National Park and four other locations in California and the northwestern state of Washington.
Now, NatureBridge is launching an East Coast center with a four-million-dollar grant from Google. The program will begin in April at the Prince William Forest Park in Virginia. Students stay for three to five days in NatureBridge programs. The activities are aimed at developing their science skills. For example, they learn about different soils and study water quality under a microscope.
Jason Morris is executive vice president of NatureBridge. He says when they are not sleeping, eating or in a laboratory, the students spend their time outdoors. Julia Washburn is associate director of education and interpretation for the National Park Service. She says in a time of budget cuts, the agency has to find ways to still meet its goals. Ms. Washburn says one of the most important services that the Park Service provides every day is nature interpretation. Park rangers (公园管理员) try to make visiting the outdoors more meaningful. Interpretation is a form of informal education. Essentially, it is a word that we use for the people in parks that explain the park or help orient(确定方向)you. So park rangers are interpreters. They orient you to the place you are in and help you make connections, emotional and intellectual connections, with the place.
小题1:Which of the following descriptions about NatureBridge is NOT correct?| A．It’s an organization working together with National Park Service to provide education. | | B．Some of the activities held by NatureBridge are financially supported by Google. | | C．Students from kindergarten to college can sign up for the organization’s activities. | | D．It’s going to cut down budget for the activities because of economic hard times. |
小题2:In which national park will the program by East Coast centre start?| A．Yellowstone National Park. | B．Prince William Forest Park. | | C．Yosemite National Park. | D．Not mentioned in the passage. |
小题3:What’s the main idea of the passage?| A．National parks are used as outdoor classrooms for students. | | B．Students are called on to be members of NatureBridge. | | C．Some famous national parks in US are attractive to students. | | D．Park rangers make visiting parks much more interesting. |
小题4: Which of the following is the correct structure of the whole passage? (Para=paragraph) |
Is your family interested in buying a dog? A dog can be a pleasant companion（伙伴） to your family, but if you choose the wrong kind of dog，you will have a lot of troubles.
Families should sit down and thoroughly discuss the possible problems before buying a dog. Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don’t know much about dogs, it is a good idea to go to the library for books about different kinds of dogs, as well as books about how to train a young dog. In reading about the different breeds(种类)you should know that a dog described(描述)as very alert(机敏灵活的)may be too active. When a book describes a dog as an excellent hunting dog, it probably means that the dog won’t be happy living in a small house. Dog breeds vary(变化)in popularity as the years go by. One of the most popular dogs these days is the German shepherd（牧羊犬）. This is because it provides protection as well as companionship（陪伴）. The family should be warned that these dogs grow up to be very big, and may be too powerful for children to control. If space is limited, a toy dog may be a good choice. These dogs are very small and easy to train. They don’t need to be walked daily, since they can exercise in the home.
小题1:According to the passage, one can get information about different kinds of dogs .| A．by going to the library | | B．by asking someone who has enough experience about different kinds of dogs | | C．by buying a dog and training it | | D．by reading books about dogs |
小题2:The German shepherd is a popular dog .| A．because it is easy to train | | B．because it is big and strong | | C．because it is powerful and friendly | | D．because it is alert and active |
小题3:Which is the best topic of the passage?| A．The care and proper selection of dogs for families. | | B．Different breeds of dogs. | | C．Responsibility for seeing that dogs are properly cared for. | | D．Different kinds of books about dogs. |

It should be very clear that we live in a most spectacular（壮观的）time. It’s a time when information is of primary importance. It’s a time when new information technologies are fundamentally transforming the world in every aspect. Among the changes, which have come upon modern society, the ones in education are probably the most obvious and influential. New information technologies are accelerating changes in education, at the same time presenting revolutionary tools with the potential to make education more efficient and more effective than ever.
The application of new information technologies has remarkably promoted the process of education. Online learning is probably the best case in point. As is often the case with “technology”, online learning may appear to be horrible; it can sound like alphabet soup sometimes. Now let’s see whether you can understand all this. You can participate in CBT at a CLC via the convenience of IDL. What does it all mean? Let me translate: GBT—Computer-Based Training; CLC—Computer Learning Center; IDL—Interactive Distance Learning. Sound complicated? Not really. Online learning is much less complicated than it seems. Students can learn at any time, anywhere, at any speed. They can make their own learning schedules and follow their own paths to suit their lifestyles. In my university, every semester there’re several online courses available, which need no class meetings or paper materials. The only thing I have to do is just to get online regularly as I wish, and download necessary learning materials. Then everything I need to know about the course is only a click away.
But online learning is not perfect; it’s like the microwave oven: it does some things better, but it is not a complete replacement for the traditional model. The traditional classroom model for education and learning is hard to leave behind. Because humans are social creatures, there’re times when we need to see each other face-to-face for interactive learning. A social and personal connection often builds effective teams, solves problems, and inspires confidence. So one possible solution is to combine online learning with the old traditional classroom learning , which not only makes the learning process faster and cheaper, but also highlights the interactions between teachers and students.
The bottom line: the Internet is the most important educational tool in the information age and online learning will become a main part of every individual’s learning experience in the future. That’s exactly how we will move knowledge from the ones who have it to the ones who need it faster and cheaper, and that’s how we’re going to survive in the information age.
小题1:The most suitable title for the passage should be “___________.”| A．Education in the information age | | B．Advantages and disadvantages of online learning | | C．Online learning vs classroom learning | | D．How to survive in the information age |
小题2:In Paragraph 3 the microwave oven is mentioned as an example to indicate that_________.| A．online learning needs improving | | B．online learning doesn’t suit everyone | | C．online learning will exist alongside the traditional model | | D．online learning is more advanced than the traditional model |
小题3:Which of the following descriptions about online learning is NOT true according to the passage?| A．It is more efficient and effective. | | B．It is convenient to both teachers and students. | | C．It stresses interactions between teachers and students. | | D．It is a cheaper way of learning. |
小题4:It can be inferred from the passage that________.| A．not all the people are in favor of online learning | | B．it is not easy to combine online learning with classroom learning | | C．in the future all the courses will be available online | | D．in a sense our survival in the world depends on online learning |

With the Tesla Roadster and other plugin (插入式) electric vehicles hitting the road，demand is growing for accessible refueling points to recharge(充电) them. Carbon Day Automotive, a Chicagobased company，has now demonstrated（演示）a solarpowered recharging point, known as the Solar PlugIn Station，which lets motorists easily charge their cars using electricity that has been produced without any environmental damage.
The Solar PlugIn Station has gone on show in Chicago as part of the city’s bid（竞标）to host the 2016 Olympic Games. According to Carbon Day Automotive，the Solar PlugIn Station on show in Chicago is part of the vital infrastructure(基础设施) required for electric vehicles in Chicago and was the focus of a recent visit by the International Olympic Committee.
These solarpowered electricity points will be used daily to fuel the city’s electric vehicles with power from the sun. By producing the electricity from pollutionfree solar cell, the CO2 emissions are reduced to zero.
“Solar energy and electric vehicles are a partnership that is one more step to reducing our dependence on foreign oil,” says Richard Lowenthal, CEO of Coulomb Technologies.Coulomb Technologies recently developed the components (部件) required for individual recharging stations，marketed as ChargePoint Networked Charging Stations.Carbon Day Automotive is the Midwest distributor for the ChargePoint stations. The Solar PlugIn Station consists of giant solar panels (电池板) that shade the tiny ChargePoint Networked Charging Station.The solar panel is connected to an underground battery pack，ready for everyday refueling.
“Without these stations it would be like driving around in a traditional car without the availability of gas stations，” says Scott Emalfarb，CEO at Carbon Day.“The day of true plugin electric vehicles will be here sooner than most people realize and the world needs to be ready to accommodate（为……提供场地）them.”

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。
