Many gardeners believe that “talking” to their plants helps them grow---it turns out that they may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret “unseen” language.
For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase(虫荧光素酶), which is what makes fireflies(萤火虫) glow in the dark.
When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out “methyl jasmonate(茉莉酸甲酯)”.
While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators(捕食者) like caterpillars(毛虫) away.
What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other.
However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot!What’s the best title of the passage?
| A． Plants Can Send Some Gas |
| B． Plants Can Communicate with Each Other |
| C． The “Unseen” Language of Plants |
| D． Plants Can’t Feel Pain |

"Experience may possibly be the best teacher, but it is not a particularly good teacher." You might think that Winston Churhill or perhaps Mark Twain spoke those words, but they actually come from James March, a professor at Stanford University and a pioneer in the field of organization decision making. For years March( possibly be wisest philosopher of management) has studied how humans think and act, and he continues to do so in his new book The Ambiguities of Experience.
He begins by reminding us of just how firmly we have been sticking to the idea of experiential learning :"Experience is respected；experience is sought；experience is explained."The problem is that learning from experience involves（涉及）serious complications（复杂化），ones that are part of the nature of experience itself and which March discusses in the body of this book.
In one interesting part of book，for example，he turns a double eye toward the use of stories as the most effective way of experiential learning. He says"The more accurately（精确的）reality is presented，the less understandable the story，and the more understandable the story, the less realistic it is."
Besides being a broadly knowledgeable researcher. March is also a poet, and his gift shines though in the depth of views he offers and the simple language he uses. Though the book is short, it is demanding；Don't pick it up looking for quick, easy lessons. Rather, be ready to think deeply about learning from experience in work and life.

The pound new Library of Birmingham（LoB）will be the most visible sign of the way the city is accepting the digitalization（数字化）of everyday life.
Set to open in 2013, the £188m LoB is already beginning to tale shape next to the Birmingham Repertory Theatre, with which it will share some equipment.
As digital media（媒介）is important to its idea. the project is already providing chances for some of the many small new local companies working at the new technologies.
Brian Gambles, the LoB project director, says it is about giving people the right tools for learning,“The aim is to mix the physical with the digital. Providing 24-hour services which can be used through many different ways. It is important to enable us to reach more people, more effectively.”
The digital library will, he says, be as important as the physical one, allowing the distant use of the services, making sure that it is never closed to the public.
Even before the LoB is complete, the public has been able to go online to visit the Virtual（虚拟的）LoB, designed by Baden, the Birmingham virtual worlds specialists. Not only have the public been able to learn about LoB, but the virtual one has also enabled those working on the LoB to understand the building and how it will work before it even opens.
Two other small Birmingham-based digital companies are working on the LoB projects. Substrat, a digital design company, is developing what it calls “enlarge reality” project. It is about the use of an exciting smart phone, an important part of the LoB which is in the early stages of development is an online library of figures of the city being built by a digital content company in Cahoots, in which users will be encouraged to add to and comment on the material.
Gambles says: “Technology will enable us to make the library’s content and services open to citizens as sever before.”

Exploit your parking space
An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to £200 or £300 a week. Put an advertisement（广告）for free on Letpark or Atmyhousepark.
Rent（出租）a room
Spare room? Not only will a lodger（房客）earn you an income, but also, thanks to the government-backed "rent a room" program, you won't have to pay any tax on the first £4500 you make per year. Try advertising your room on Roomspare or Roommateeasy.
Make money during special events
Won't want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money, Grashpadder can advertise your space.
Live on set
Renting your home out as a "film set" could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free-but you will be charged if your home gets picked.
Use your roof
You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment(around￡14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier, which could prevent you from changing the roof.

If you earn ￡5000 from renting a room in one year, the tax you need to pay will be based on.

It’s 5:00 in the morning when the alarm (闹钟) rings in my ears. I roll out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD insanity. Sweat pours down my face and into my eyes. My heart races as I face my body to finish each movement. As I near the end of the exercise ,I feel extremely tired, but a smile is of my face. It’s not a smile because the DVD is over , but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping, smoking , food, work, or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother’s chocolate cake. They raise their eyebrows, surprised by my “no thank you,” or by my choice to have a salad. Over the years , I have learned it’s okay to just say “no.” I shouldn’t feel sorry for refusing food that I don’t want to eat.
So what drives me to roll out of bed at 5:00 a.m.? What gives me the reason to just say to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety, increases self –confidence and energy, extends life and above all improve my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right.

The Coalition for the Homeless is an organization that seeks to address the needs of the homeless population in the United States. It is a network of offices, some of which provide food and houses for the homeless population, and some of which fight for the passing of laws that of over two hundred million people living in the United States,up to three million are homeless—and the number is still growing. Since the late 1970s,fast rising house prices,large cuts in government supported housing programs, and economic recession(经济衰退)have made it impossbile for many Americans to meet housing costs. Sadly, this has resulted in a number of persons being forced to leave their homes and/or unable to find new affordable homes.
