There is no escape from it and I was beginningto be driven mad by it. In an attempt to recapture some peace, I travelled to a temple, a small poor house and a mine 2km underground — all very quiet but not the holy place of silence. The one place I was most excited about visiting was the anechoic (无回声的) hall.Ironically, far from being peaceful, most people find its perfect quiet upsetting. Being deprived of the usual sounds can result in fear. The presence of sound means things are working; it's business as usual — when sound is absent, that signals dangers. A violinist tried it and knocked on the door after a few seconds, demanding to be let out because he was so disturbed by the silence.I booked a 45minute period — no one had managed to stay in for that long before.I felt anxious for two reasons: would I go mad and tear off my clothes? Or would I simply be disappointed because it wasn't as enjoyable as I'd hoped?When the heavy door shut behind me, I was thrown into darkness. For the first few seconds, being in such a quiet place made me feel nervous. I tried to hear something and heard…nothing. Then, after a minute or two, I became aware of the sound of my breathing, so I held my breath. The sound of my heartbeat became apparent — nothing I could do about that. As the minutes went by, I started to hear the blood rushing in my body. Your ears become more sensitive as a place gets quieter, and mine were going overtime. I heard my skin moving over my head, which was a strange noise I couldn't explain. The feeling of peace was spoiled by a little disappointment —this place wasn't quiet at all.I didn't feel afraid and came out only because my time was up; I would happily have spent longer in there. Everyone was impressed that I'd beaten the record, but having spent so long searching for quiet, I was comfortable with the feeling of absolute stillness. Afterwards I felt wonderfully rested and calm.I found that making space for moments of quiet in my day is the key to happiness — they give you a chance to think about what you want in life. How can you really focus on what's important if you're distracted by constant background noise? If you can occasionally become master of your own sound environment —from turning off the TV to moving to the country, as I did — you become a lot more accepting of the noisesof everyday life.1. Why did the writer love to travel everywhere?A. To find a place to enjoy himself.B. To study the customs of other countries.C. To discover whether absolute silence exists.D. To escape from the background roar of vehicles.2. It is implied in Paragraph 2 that astronauts ______.A. should be trained in the anechoic hallB. should learn to cope with the silence of spaceC. should knock on the door to make noisesD. should sense something was wrong by noises3. The writer could hear the following in the anechoic hall except ______.A. breathingB. heartbeatC. blood rushingD. light4. We can infer from the passage that ______.A. you'd get more sensitive in a quiet placeB. you'd have to be dead for absolute silenceC. the writer felt tired and calm when he came outD. the writer went out of the hall due to extreme fear5. Which of the following will the writer agree with?A. His desire for silence changed his life.B. His experience narrowly drove him mad.C. We should try our best to live without noises.D. Our sufferings are bound to be linked to noises.Ⅳ.阅读填空(10 min.)When you do business online, remember one of the most important factors in online success is list building. No matter what goals you're seeking with your online activities, building a good contact list is vital for a successful outcome. List building plays a major role in developing good relationships with your site's customers and visitors. It can be used to get more sales for your site or business.For these reasons contact building should be high on your list when you're marketing or promoting on the web. Fortunately, list building is an easy process that any site or webmaster can quickly set up as long as you understand two simple elements. To be really successful, your list building must combine these two key elements. Without these you will probably find building your contact list difficult and slow going. So it is worth your while to fully understand these two factors in your list building.Value — It should offer important information, quality content, special deals / discounts, and more importantly, it should offer a valuable relationship or connection to an expert in the subject area of the list.Subscribers (订户,用户) must benefit from joining your list. If you're building a list, just write down all the benefits someone would receive from joining your site or list, including receiving important information, getting special valuable content, receiving special deals / discounts, getting training videos and getting timely announcements or news. Don't forget there may also be a psychological reason for joining your list — many people like being part of a group or membership site. It's human nature. Everybody likes to feel included.Free whatever you offer — make sure it is free. The quickest way to build any list is to give away free valuable content, information, videos, reports, ebooks, discounts, prizes…everybody loves a free gift. Just make them an offer they can't refuse. This has more to do with the nature of your gift and the kind of contacts you're building — giving away free buying guides on how to purchase real estate, fast cars, LCD TVs, laptops…will definitely attract the right “buying customer”. If you're into selling, you just have to adjust your marketing to combine the free element correctly. In addition, giving away something free is the first step in starting an ongoing relationship with your subscribers. It gets the ball rolling.Ⅴ.写作(25 min.)假定你是张峰,一家英文报社邀请你写一篇中学生对网络使用情况的报道。

We suddenly can’t remember where we put the keys just a moment ago, or an old acquaintance’s name, or the name of an old band we used to love. As the brain fades, we refer to these occurrences as“senior moments”.This loss of mental focus can potentially have a disadvantageous effect on our professional, social, and personal well-being.It happens to most of us, but is it inevitable(不可避免的)?Neuroscientists are increasingly showing there’s actually a lot that can be done. It turns that the brain needs exercise in much the same way our muscles do, and the right mental exercise can significantly improve our basic cognitive functions. Thinking is essentially a process of making neural connections in the brain. Scientists believe intelligence can expand according to mental effort and practice.Now, a new San Francisco Web-based company has taken it a step further and developed the first “brain training program”to help people regain their mental sharpness. Called Lumosity, it was designed by some of the leading experts in neuroscience and cognitive psychology from Stanford University.Lumosity, is not only an online place to exercise your mental skills.That’s because they have integrated(整合)these exercises into a Web-based program allowing you to systematically improve your memory and attention. The program records your progress and provides detailed feedback on your improvement. Most importantly, it constantly modifies the games you play to build on the strengths you are developing—much like an effective exercise routine requires you to increase resistance and vary your muscle use.Does it work?Apparently it does. In controlled clinical trials, Lumosity was shown to greatly improve basic cognitive functions. One study showed students improved their scores on math tests by 34 percent after using Lumosity for six weeks, significantly greater gains than those made by other students in the same class, not training with the Lumosity program.The company says its users have reported clearer and quicker thinking, improved memory for names, numbers, directions, increased alertness, awareness, mood, and better concentration at work or while driving.Lumosity is currently offering a free trial of their program to new users so that you can see how well it works before you decide to subscribe.1. Many middle-aged pe ople’s memory is decreasing because.A. their brains are injuredB. their brains don’t have enough oxygenC. their brains aren’t supplied with enough bloodD. their brains are growing old2. What’s the main idea of the fourth paragraph?A. Our muscles need to exercise.B. Scientists believe our brain needs improving by running.C. Scientists believe proper mental practice can improve intelligence.D. Our muscles have connections with our brain.3. Which of the following is NOT the function of Lumosity?A. Improving your memory and attention.B. Increasing your resistance for diseases.C. Recording your advance and offering feedback in detail on your improvement.D. Modifying the games you play to build on the strengths you are developing.4. If you want to order Lumosity, what should you do first?A. You can get a free trial of their program.B. You can pay money for it first.C. You can first get it and then pay for it.D. You can think quickly.Ⅲ. 任务型阅读请认真阅读下列短文, 并根据所读内容在文章后表格中的空格里填入一.个.最恰当的单词。
