成都七中二诊模拟英语作文The air was crisp and the sun was just beginning to peek over the horizon as I made my way to Chengdu No. 7 Middle School for the second diagnostic simulation exam in English. As I approached the familiar building, I couldn't help but feel a mix of nerves and excitement coursing through me. This exam would be a crucial step in determining my progress and readiness for the upcoming high-stakes tests that would shape my academic future.As I entered the school gates, I was greeted by the hustle and bustle of my fellow classmates all making their way to the exam hall. The air was thick with a palpable tension as we all knew the importance of this moment. I took a deep breath and steeled my resolve, determined to give it my absolute best.Once inside the exam hall, I quickly found my assigned seat and began to review the materials I had prepared. The questions on the exam covered a wide range of topics, from advanced grammar and vocabulary to complex reading comprehension and essay writing. I knew that I had put in countless hours of studying and practice, butin that moment, all of that seemed to fade away, replaced by a mix of uncertainty and self-doubt.As the exam began, I forced myself to focus on the task at hand, carefully reading each question and formulating my responses. The time seemed to fly by, and before I knew it, the proctor was announcing that there were only 15 minutes left. I quickened my pace, determined to complete every section to the best of my ability.When the final bell rang, signaling the end of the exam, I felt a wave of relief wash over me. I had done my best, and that was all that mattered. As I handed in my exam booklet and made my way out of the hall, I couldn't help but reflect on the journey that had led me to this point.I remembered the countless hours spent poring over textbooks and practice materials, the late nights spent studying with my classmates, and the endless encouragement and support from my teachers. It was all of these elements that had brought me to this moment, and I couldn't help but feel a sense of pride and accomplishment.As I walked back home, I couldn't help but think about the implications of this exam. The results would not only determine my own academic standing, but they would also play a crucial role in shaping the trajectory of my educational and career path. Thepressure to succeed was palpable, but I knew that I had to stay focused and keep my eyes on the prize.In the days that followed, I anxiously awaited the release of the exam results. When they were finally announced, I was relieved to see that I had performed well, scoring in the top percentile of my class. This was a testament to the hard work and dedication that I had put in, and it filled me with a sense of pride and accomplishment.But as I reflected on this achievement, I couldn't help but feel a sense of humility as well. I knew that there were countless other students out there who had worked just as hard, if not harder, than I had. The competition was fierce, and I knew that I would have to continue to push myself to the limit if I wanted to maintain my edge.As I looked ahead to the future, I couldn't help but feel a sense of excitement and trepidation. The road ahead would be long and challenging, but I was determined to rise to the occasion. I knew that the skills and knowledge I had gained through this exam would be invaluable as I continued on my academic journey, and I was excited to put them to the test.In the end, the Chengdu No. 7 Middle School Second Diagnostic Simulation English Exam was a pivotal moment in my academic career. It was a testament to the hard work and dedication that I hadput in, and it served as a reminder of the importance of staying focused and committed to my goals. As I look back on this experience, I can't help but feel a sense of gratitude and appreciation for all of the people who have supported me along the way. It is with this spirit of determination and resilience that I will continue to strive for excellence in the years to come.。

deeper questions, it turns out that they like to shop．Men generally like to shop for books, music and hardware．But if you ask them about the shopping they do for books or music, they‘ll say, ― Well, that‘s not shopping．That‘s research．‖In other words, what men and women call ―buying things‖ and how they approach that task are different．Women will wander through several 1,000-square-meter stores

from their moms and older sisters, but they also learn to shop by examining articles in magazines like Seventeen,‖ City University Zukin says．―And although men‘s magazines such as GQ and Esquire have long had shopping articles, it‘s TV that has the eye of young male shoppers,‖ say Ann and Zukin．―Television shows are used by young men in the same way Seventeen magazine or Lucky is used by girls,‖ says Zukin, ―to help make clothing and toiletry（化妆品）choices．‖―Of course, there are men who love to shop and are proud of it,‖ Loyola‘s Ann says．And that is important no matter whether you buy a car or a frying pan．All men love to buy but don‘t want to get cheated．Ann adds, ―There actually are men who are interested, for example, in cooking or shopping or chinaware or things around the home-----they

lose weight successfully and for good．Dieting can be a real challenge so setting realistic goals and remaining focused on them is important．Otherwise as this research shows, women could end up heavier than when they started．The ‗Food: Body: Mind‘ report was publicized by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviors around weight loss．Six in ten said they are currently on a diet and one in five women said they are on a continuous diet．It found the most common triggers to start dieting was seeing their reflection in the mirror , preparing for a summer holiday or unflattering photos posted on social networking sites．Other popular reasons include comments by friends or relatives or their other half．However, the study showed that one in ten give up within one day, while almost a fifth manage to make it to a week or more．The average is ten days．Many blamed pressure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal．Others blamed colleagues, who tuck into fatty lunches and snacks unaware of the effect it has on the dieter, while mothers who polish off their children's leftovers was another common cause of weight gain．49．Which of the following might be the best title for this article?A．Three reasons to fail in dietingB．Important things for successful dietC．Four in ten women gain weight on dietsD．Obesity: problem for 61．4% adults in UK50．In the UK, women who go on a diet __________．A．are all overweight or obeseB．all fail because they are not persistent enoughC．are likely to gain weight again after reaching their ideal weightD．end up heavier than when they start to diet51．The underlined word ―triggers‖ in Paragraph 4 probably means_________．A．effects B．causes C．examples D．imagination52．Which of the following is NOT the reason why many people quit dieting very soon?A．The pressure they put on themselves to lose weight quickly．B．Colleagues who give them fatty lunches and snacks．C．Leftovers of children‘s taken by their mothers．D．Reflections they see in the mirror．DI am sure that everybody in his／her life has used computers．Nowadays you can feel their presence everywhere—at home，at school，at work and they certainly make life easier．On the other hand，there are people who can work without them．Anyway, I believe their presence is a good thing．Life with them seems less difficult and more comfortable．Y ou can use them to choose your meal，to withdraw your money，and also to save your time，because these operations are all controlled by computers．Therefore，you can hardly imagine the modern world without them；the whole planet seems to be one big computer society．Nevertheless，problems can often appear in this area，too．To have a computer means you have to be quite rich and have the necessary skills to use it．However, think about questions like，―Are computers available for everyone, for rich and poor people，for people from villages and people from cities? Aren‘t they too expensive? Is everyone able to learn how to use them and does everyone have the chance to access and work with them? How could everything in the future be dependent on them?‖Therefore，I think our society will be divided into two parts．One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out of soc iety and will actually be left far behind the other group．Another question that bothers me is，computers are important and they‘re good things in our life, but they aren‘t everything．They are good as a help at school, quite often as entertainment, especially for young people, as an necessary tool to help in research etc．, but I think we shouldn‘t be so dependent on them, because computers are only machines and machines can‘t feel anything, can‘t be human and sympathetic, and every action performed by computer can be interfered（干涉）with could cause these machines to crash or work badly．In conclusion, I would like to say I am not against computers．I use computers too, but people should be wary all the time．53．Which of the following best shows the structure of the passage?①=Paragraph1 ②=Paragraph2 ③=Paragraph 3 ④Paragraph4 ⑤=Paragraph554．By saying―wary‖（in the last paragraph），the author is trying to say,―People should‖．A．be strongly for the use of computers because of its convenienceB．be careful with computers that will also cause problemsC．master more necessary computer skillsD．not do something that causes computers to work badly55．In the third paragraph，the author presents his idea by ．A．asking questions for people to think aboutB．giving examples to support his argumentC．raising questions and answering themD．expressing his opinion directly56．The author‘s main purpose in writing the passage is to．A．encourage us to use computers in our societyB．advise us to say no to computers from now onC．remind us to care about the problems that computers bringD．inform us that computers has become a necessary part of our lifeEEBay will launch an online group gift-buying service today designed to make it easier for several people to chip in, buy and pay for gifts using their social-network and e-mail contacts．EBay North America Vice President Christopher Payne says it is going to be a major step forward in social commerce, which is the still-small practice of selling products through social networks．Online retail experts aren't as certain, but eBay says the new tool makes it easier for friends and relatives to chip in （凑钱）for gifts because it eliminates the headache of collecting contributions．It can also be used for family members to pitch in to buy, say, an expensive child seat for a mother．Anything on eBay that's available immediately, rather than up for bid, can be purchased this way starting today at groupgifts．eBay．com．If members of an extended family wanted to buy a gift for one member, one person would choose a gift— or have one recommended by eBay —and invite family members to chip in using Facebook or e-mail．Those who wanted to join in would choose an amount to contribute （or agree to pay a requested amount）and pay using either PayPal or a credit card．They could also add a personal note．If enough people don't chip in, the organizer can ask people to contribute more or choose a less expensive gift．"I see myself using this most in cases when I typically might not buy someone what they want because of price," says Nitzan Shaer of Boston, who was part of an online test of the site．EBay, with its 200 million products, millions of sellers and mobile commerce proficienc y, is a logical place to pull together the products, groups of buyers and payment tools, Payne says．At least 12 sites, such as FrumUs．com and eDivvy．com, facilitate （便于,利于）group purchases but don't sell products．Although a handful of retailers, including Victoria's Secret and 1-800-Flowers, sell products through Facebook, Payne says he expects social commerce will take off as rapidly as shopping using mobile devices．EBay did more than $600 million in sales on mobile devices last year and expects mobile sales to increase to $1．5 billion this year．Although one in five consumers surveyed said they'd used Facebook for shopping in the past year, 88% said they would not be buying holiday gifts through a social network, mobile phone or smartphone．Of these, 26% were reluctant because of security or privacy concerns, and 20% were unclear about the benefits of using phones or Facebook to shop．57．What procedure should be followed if your extended family intends to buy your grandpa an 80th birthday gift?①Asking f amily members to contribute more money if enough members don‘t chip
