2015年普通高等学校招生全国统一考试新课标全国卷Ⅱ英语试卷和答案解析
2015年普通高等学校招生全国统一考试（新课标全国卷Ⅱ）英语AMy color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn't fit.I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night.Fortunately, I didn't get any channels showing all-night movies or I would never have gotten to bed.Then I started developing a problem with the set that involved static(静电)noise. For some reason,when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉)shaking my set.When neither of these methods removed the static noise,I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether. My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble.1. Why did the author say he was fooled into buying the TV set?A. He got an older model than he had expected.B. He couldn't return it when it was broken.C. He could have bought it at a lower price.D. He failed to find any movie shows on it.2. Which of the following can best replace the phrase“signed off”in Paragraph 1?A. ended all their programsB. provided fewer channelsC. changed to commercialsD. showed all-night movies3. How did the author finally get his TV set working again?A. By shaking and hitting it.B. By turning it on and off.C. By switching channels.D. By having it repaired.4. How does the author sound when telling the story?A. Curious.B. Anxious.C. Cautious.D. Humorous.BYour house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious (难为情的) when they're in poorly lit places—and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it's time to repaint, go blue.Don't forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.5. The text is especially helpful for those who care about ________.A. their home comfortsB. their body shapeC. house buyingD. healthy diets6. A home environment in blue can help people _______.A. digest food betterB. reduce food intakeC. burn more caloriesD. regain their appetites7. What are people advised to do at mealtimes?A. Eat quickly.B. Play fast music.C. Use smaller spoons.D. Turn down the lights.8. What can be a suitable title for the text?A. Is Your House Making You Fat?B. Ways of Serving DinnerC. Effects of Self-ConsciousnessD. Is Your Home Environment Relaxing?CMore students than ever before are taking a gap year(间隔年)before going to university.It used to be called the“year off”between school and university.The gap-year phenomenon originated(起源)with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year.This year,25,310 students who have accepted places in higher education institutions have put off their entry until next year,according to statistics on university entrance provided by the University and College Admissions Service(UCAS).That is a record 14.7% increase in the number of students taking a gap year.Tony Higgins from UCAS said that the statistics are good news for everyone in higher education.“Students who take a well-planned year out are more likely to be satisfied with,and complete,their chosen course.Students who take a gap year are often more mature and responsible,”he said.But not everyone is happy.Owain James,the president of the National Union of Students(NUS),argued that the increase is evidence of student hardship—young people are being forced into earning money before finishing their education.“New students are now aware that they are likely to leave university up to ￡15,000 in debt.It is not surprising that more and more students are taking a gap year to earn money to support their study for the degree.NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacation periods,”he said.9. What do we learn about the gap year from the text?A. It is flexible in length.B. It is a time for relaxation.C. It is increasingly popular.D. It is required by universities.10. According to Tony Higgins,students taking a gap year .A. are better prepared for college studiesB. know a lot more about their future jobsC. are more likely to leave university in debtD. have a better chance to enter top universities11. How does Owain James feel about the gap-year phenomenon?A. He’s puzzled.B. He’s worried.C. He’s surprised.D. He’s annoyed.12. What would most students do on their vacation according to NUS statistics?A. Attend additional courses.B. Make plans for the new term.C. Earn money for their education.D. Prepare for their graduate studies.DChoose Your One-Day Tours!Tour A—Bath & Stonehenge including entrance fees to the ancient Roman bathrooms and Stonehenge—￡37 until 26 March and ￡39 thereafter.Visit the city with over 2,000 years of history and Bath Abbey, the Royal Crescent and the Costume Museum.

For each question or statement there are 4 choices marked A, B, C and D. You should make the correct choice and mark the corresponding letter on the Answer Sheet with a single line through the center.In giving a business presentation, many speakers think that if their idea is strong, their audience will get it readily. They feel discouraged when the audience is unable to understand their presentations. That happens a lot especially when technical experts are invited to make a product presentation to a group of users.What can we do to make a business presentation easier to understand? In my view, good presentations have always been simple and visual. In an effective business presentation, the fewer the points, the better the message gets passed on. You focus on the depth of coverage instead of the width(广度) of coverage. Additionally, you make your ideas visual and relevant, so the message is understood better and remembered longer. Great business presenters relate their ideas and concepts to their audience by using simple, powerful diagrams instead of relying on text-based slides. In fact, drawing diagrams forces a presenter to make the idea clear even at the preparation stage. It is impossible to draw a diagram when you are not clear about an idea. When your idea is clear, it is easier to transfer it. Most audiences understand a diagram faster and remember it longer. This possibly explains why most of thememorable presentations have been visual in nature.36.Many speakers believe that the stronger their idea,.A)the more powerful their speech will beB)the more meaningful their speech will beC)the more easily the audience will understand itD)the harder the audience will find it to follow37.Why are you advised to give fewer points in your presentation?A)To pass on the messages better. C) To allow audience to take notes.B)To avoid wasting too much time. D) To leave more time for questions.38.The speaker can help the audience remember the message longer by.A) displaying text-based slides C) focusing on the width of coverageB) avoiding long technical terms D) using simple and powerful diagrams39.The underlined word “transfer” in this passage most probably means.A) create B) pass on C) take off D) describe40.This passage is mainly about.A) how to make an effective business presentationB) how to present strong ideas in a presentationC) how to focus on the depth of coverageD) how to prepare a powerful diagramTask 2Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 to 45.Blue Jeans Company was established in October 2012 and operates as a partnership (合伙企业）between Elena Horowitz and James Foster.

2015年国家电网公司计算机水平考试实用教程上机操作模拟题(三)
生物资发电技术是将生物资能源转化为电能的一种技术，主要采用农作物秸秆和林业烧毁物作为发电燃料，是以又称之为秸秆发电技术。
秸秆是一种很好的清洁可再生能源，是最具开发利用潜力的新能源之一，具有较好的经济、生态和社会效益。
每两吨秸秆的热值就相当于一吨标准煤，而且其平均含硫量只有3.8‰，而煤的平均含硫量约达1%。
在生物质的再生利用过程中，排放的CO2与生物质再生时吸收的CO2达到碳平衡，具有CO2零排放的作用，对缓解和最终解决温室效应问题具有潜在的贡献价值。
秸秆发电，就是一农作物秸秆作为主要燃料的一种发电方式，有分为秸秆气化发电和秸秆燃烧发电，秸秆气化发电是将秸秆在缺氧状态下燃烧，发生化学反应，生成高品位、易输送、利用效率高的气体，利用这些产生的气体再进行发电。
但秸秆气化发电工艺过程复杂，难以适应大规模应用，主要用于较小规模的发电项目。
丹麦BWE公司是亨誉世界的发电厂设备研发、制造企业之一，长期以来在热电、生物发电厂锅炉领域处于全球领先地位。
丹麦BWE公司率先研发的秸秆生物燃烧发电技术，迄今在这一领域仍是世界最高水平的保持者。
在这家欧洲菩名能源研发企业的技术支撑下，1988年丹麦诞生了世界上第一座秸秆生物燃烧发电厂。
目前丹麦已建立了130多家秸秆发电厂，还有一部分烧木屑或垃圾的发电厂也能兼烧秸秆。
秸秆发电等可再生能源占到全国能源消费量的24%以上，丹麦的秸秆发电技术已走向世界，并被联合国列为重点推广项目，瑞典、芬兰机西班牙等多个欧洲国家利用植物秸秆作为燃料发电的机组已有300多台，其中位于英国坎贝斯的生物质能发电厂是目前世界上最大的秸秆发电厂，装机容量38万MW。
总投资于5亿丹麦克朗。
中国，2008年前后几年间，国家电网公司，五大发电集团等大型国内、民营以及外资企业纷纷投资参与中国生物质发电产业建设运营，可以看出，中国生物质发电产业的发展正在流入佳境。
