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 moreeffectively over the Internet. It's an easy way of hosting and attending conferenceswithout having to leave the office. Each of the people involved in a Web conference willbe posted an invitation to the conference with the time and date of the Web conference onit. When the conference is ready to begin, all participants (参与者) must sit at theircomputers and they will be connected over the Internet.With Web conferencing all participants attend the conference from the comfort of their own desk. Obviously, in doing this no fuel is used in traveling to and from a conference, and less work time is taken up in attending a conference.Any material to be used during Web conferencing 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 used by the participants' personal computers. Similarly conference organizers don't have to arrange for food or overnight accommodation (住宿) for participants of their conferences. 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.So Web conferencing is much cheaper and greener and more people are willing to host and attend a Web conference.1. What is the passage mainly about?A. Ways of protecting the environment.B. Green benefits of Web conferencing.C. Ways of hosting a Web conference.D. Impact of Web conferencing on costs.2. According to Paragraph 1, many companies use Web conferencing because they ________.A. are interested in using any new technologyB. believe that Web conferencing is more convenientC. want to do something to protect the environmentD. haven't enough money to hold a traditional conference3. The participants of a Web conference ________.A. will be e-mailed an invitation before the conferenceB. are required to sit in an office togetherC. will receive many paper materialD. must have access to the Internet4. Which of the following words best describes the author's opinion about a Web conference?A. Useless.B. Environmentally friendly.C. Inconvenient.D. Money-consuming.BThe upcoming big Apple TV will use iPhone's Siri “personal assistant” as its main control method － and will use touch control as a backup (支持).Leaks from Apple's manufacturing chain say that Apple has been working on prototype sets (原型机) since September —according to a design blueprint laid down by late CEO Steve Jobs. His “eureka (我找到了！)”moment was realising that Siri's voice control could be used to ‘talk’ to the set.Jobs was referring to the realisation that the television should be voice-controlled — using the natural-language algorithms of Siri (Siri的自然语言系统) so that people talk to the set as they would to someone sitting next to them on the sofa.Mr Jobs, who died earlier this month, told author Walter Isaacson: “It will have the simplest user interface (界面) you could imagine.”Apple executive Jeff Robbin, who was behind the iPod and iTunes Store, is reportedly “now guiding Apple's internal development of the new TV effort”.It's not the first attempt to bring more “natural” controls to televisions­companies such as One For All already make gesture­controlled remotes which you simply “wag” at the scre en, and Microsoft's Xbox Kinect camera can be controlled by voice.But the highly sophisticated Siri software could represent a huge leap forward for the technology.A third party (第三方) analysis suggests the device will hit shelves by late next year or 2013, based on research of Apple's patent portfolio (专利组合), its investments in manufacturing facilities and “securing supplies of LCD screens”.Apple spokeswoman Trudy Muller declined to comment on the Bloomberg report.It has been widely-speculated (猜测) Apple will launch its own brand of touchscreen televisions running its iOS platform.5. What's the best title of the passage?A. Apple's TV “to be voice controlled”B. A design blueprint by CEO Steve JobsC. A huge leap forward for the technologyD. Apple will launch touchscreen televisions6. The underlined word “wag” in Paragraph 6 probably means ________.A. shakeB. removeC. pressD. throw7. The following are the features of the upcoming big Apple TV except that________.A. the device may make people talk to the set as they were talking to someone sitting next to themB. the device may have the simplest user interfaceC. the device may will use touch and voice controlD. the device will hit shelves by late next year or 20138. His “eureka (我找到了！)”refers to ________.A. the television should be voice-controlledB. the natural-language algorithms of Siri can be usedC. prototype sets can be developedD. the simplest user interface can be foundB卷Ⅰ.完形填空After finishing working at the hospital that day, I was driving home after a particularly busy night call.

Then slowly, these rocks broke up into smaller and smaller pieces. Finally stones, pebbles (砾石) and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil.There are many ways in which large pieces of rock break up into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and cracks (裂缝) in the rock, which become bigger and finally the rock breaks up into smaller pieces.The moving water of streams and rivers also helps to break up rocks. As the watermoves along, it carries with small pieces of rock.These rub the larger ones. Thus, thelarger rocks are worn down to smaller pieces.The heat of the sun is also helpful in breaking up rocks. When the sun shines, therocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also playsa part in making soil. Water in the cracks can turn into ice in cold weather. As this happens,it becomes bigger and the cracks become wider, and finally break up into smaller pieces.1. According to the passage, soil ________.A. forms very slowlyB. is a mixture of stones, pebbles and sandC. makes up the layers of the earthD. is becoming smaller and smaller2. Which of the following speeds up the breaks of rocks most?A. Hot weather.B. Cold water.C. Sharp changes in temperature.D. More dead plants in the cracks.3. Which of the following is NOT true?A. The remains of many plants and animals can form soil.B. If a large rock never moves, it will never break up.C. Even if a large rock never moves, it will break up.D. Ice in the cracks helps to break up rocks.4. The best title for this passage should be ________.A. Soil from rocksB. Ways to break up rocksC. Soil on the earthD. Soil, outmost layer of the earthⅢ.选做题任务型读写How do you enter a room full of strangers? Do you walk right in full of confidence? Or do you try to slip in without being noticed? The way you go into new situations shows your level of self-confidence.In life, we admire those who do their tasks confidently. We prefer people who appear to know what they're doing. But where does that confidence begin?Developing self-confidence starts very early. It's parents' role to get kids on the right track toward becoming confident people. To help that process, parents should always offer more praise than criticism (批评). That can be done by focusing on the child's strengths. Parents should encourage their children to try new things and take risks.When children make mistakes, their parents should still let them know that they are loved. Children whose parents do these things will likely develop into confident adults. But self-confidence still doesn't come easily. So what's the solution?With most things in life, practice makes perfect, and that is true of confidence skills. The more you practice them, the easier they will become.Always hold your head high and look people in the eye. Answer questions clearly and confidently. The way you walk shows others how confident you are.Focus on the things that you do well, and look for opportunities to use those abilities.Keep an item in clear view that reminds you of a recent success. It could be a good test score or a prize from a contest. Remind yourself that one success often leads to the next.Prepare thoroughly for every project. You'll approach the task more confidently knowing that you're ready.All humans fail at times, and you will too. But don't allow mistakes to trouble you. Learning from mistakes helps you face the same situation later without fear.Even with practice, you will never be perfect.
