Many businesses today use conferences as a means of discussing new plans of the company. As people are paying more attention to the environment and green problems, more businesses are looking for ways to reduce their negative effect on the environment. Many businesses do this by using Web conferencing. Web conferencing is a technology that allows people to communicate more effectively over the Internet. It's an easy way of hosting and attending conferences without having to leave the office. Each of the people involved in a Web conference will be posted an invitation to the conference with the time and date of the Web conference on it. When the conference is ready to begin, all participants   must sit at their computers and they will be connected over the Internet. With Web conferencing all participants attend conference from the comfort of their own desks. Obviously, in doing this no fuel is used in traveling to and from a conference, and less work is taken up in attending a conference. Any material to be used during Web conference is simply e-mailed to all the participants before the conference. Participants can then either choose to print material or read it on screen. This not only saves paper but also greatly reduces mailing costs for the business. As a conference hall or business center isn't being used, it means that the only power that is used is the power that is used by the participants' personal computers. Similarly, conference organizers don't have to arrange for food or overnight accommodation. All this means that less energy is used. Often in business some companies actively choose to do business with other companies that do many things to reduce their negative impact on the environment. And Web conferencing helps you show other businesses that you are willing to work hard for the green cause. The participants of a Web conference   _  . A) will be e-mailed an invitation before the conference. B) are required to sit in an office together. C) will receive many paper materials. D) must have access to the Internet.

Just three years since Lady Gaga had her first US number one single, the pop star has claimed the top spot in Forbes magazine's annual Celebrity 100 list.   The popular star moved up four positions from last year and has knocked TV chat show host Oprah Winfrey of the top spot.    But how has the singer become such a global phenomenon in such a short space of time ? Two experts in music, fashion and social networking give their opinions.  George Ergatoudis ----Head of Music Radio1   " The key thing is Lady Gaga realized by using all the current social networking sites, and connecting that with her fashion, she has become an all-round star. Every time she goes out the door she looks different. She's getting photographed, she's aware of that and she's using it by updating her look literally on a daily basis.   Another key thing wat that quite early on, her record label was showing how gifted she is as a musician. The music she makes, the songs she writes and the production she has are all brilliant contemporary pop music. She literally is turning into a global superstar." Calum Brannan ---Co-Founder of social Networking support company crowd Control HQ    "Social media is a reflection  of what we love, so people are becoming very good at sharing exactly what they love and the brands and musicians they love.    The fact she has 10 million Twitter followers and 30million Facebook fans is a massive reflection on Lady Gaga and the influence she has. Once out there, Twitter and Facebook help keep that person's profile  alive. Her fans are always talking about her and sharing everything she does even when she's not on stage or in concert.   I think even if she wasn't on Facebook and Twitter, her fans and followers would put her there anyway. But the most important thing is,she is on there and she's using them." Both George Ergatoudis and Calum Brannan owe Lady Gaga's success to   _  . A) hard work B) social media C) her faithful fans D) her music talents

Q: Sometimes people call each other  " scared cat" , but have you ever thought about this expression? When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its blood-stream.  If the danger continues, this animal will do one of the two things. It will defend itself, or it will run away as fast as it can. Something like this also happens to people. When we are excited, angry, scared, or aroused by other emotions, our bodies go through many physical changes. Our hearts beat faster, and our muscles get tense. All of these changes make us more alert and ready to react. We, too, get ready to defend ourselves or run. Human beings, however, have a problem. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger - and regretted later? Have you ever shouted at a teacher or told somebody you were lonely and then wished later you had kept your mouth shut? It isn't always wise to express your feelings freely. Does this mean that it's always smarter to hide our feelings? No! If you keep feelings like anger hidden away or bottled up inside, your body stays tense. Physical illnesses can develop, and you can feel disturbed badly inside. _ can actually be bad for your health. Feelings that you keep all bottled up inside don't just go away. It's as if you bought some bananas and stuck them in a cupboard. You might not be able to see them, but before long you'd smell them. And if you opened the cupboard, chances are you'd see little fruit flies hovering  all over them. They'd be rotten. You can try to treat emotions as if they were bananas in the cupboard. You can hide them and you can pretend they don't exit, but they'll still be around. And at last you'll have to deal with them, just like those bananas. The author mainly intends to tell us to   _   . A) make us face the problem that we have to deal with feelings B) give us some advice on how to express our feelings C) tell us that it isn't good to keep feelings inside D) make us know that it isn't always wise to express our feelings freely

Q: Besides containing attractive flowers, trees and other plants that beautify the community, eco-friendly rain gardens are healthy for the environment and the people living and working nearby. A rain garden  is not very different from a traditional garden. It is just a far more eco-friendly garden. Usually it is built lower than the ground. Rain gardens make smart use of rain and storm water by temporarily holding water from rain and storms and letting it soak slowly into the ground before it runs into streams or enters the public drinking water supply. Thus, a rain garden keeps the water, allowing it to be used as needed by plants in the rain garden, rather than flowing immediately into nearby streams and going unused. The water will soak slowly into the ground within a day or two. This creates an advantage that the rain garden does not allow mosquitoes to breed. This is a simple, attractive, and eco-friendly "green" way to treat storm water. What's more, planting a rain garden helps reduce pollution and improve the environment. Without using expensive machinery and chemicals, rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%. Native plants are recommended for rain gardens because they are more used to the locals climate, soil, and water conditions. They may attract local wildlife such as native birds. Water your rain garden immediately after planting and once a week, unless you have had at least an inch of rain during the week. Once the native plants establish the necessary root system, it will require little care. Often, local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems. However, you don't need to be a professional environmental engineer to create a rain garden. As long as you're eco-conscious homeowners, you can help the environment by building smaller rain gardens in your yards. Who are the intended readers of the passage? A) Homeowners. B) Students. C) Engineers, D) Educators.
