AAmsterdam guidebookTime out Amsterdam guide is written by writers who live in the city, with a unique insider perspective on local culture. This guide is filled with useful tips and ideas on everything from room rates to the detailed clear color maps, from world-class museums and markets to the city’s great bars and restaurants, and top sightseeing tips from the popular sites to the unusual.Customer reviewsI bought several books on a recent trip to Amsterdam, but this was the only one I used while walking and sightseeing. The book’s small size makes it convenient to hold, but don’t be fooled: this book is jam-packed with useful information. And, unlike the Eyewitness Travel Guides, which are also great, this book lists a good number of budget accommodations and also provides important details that I found, for the most part, very accurate. The section on what to do outside Amsterdam was also extremely useful. My glasses broke during the trip, and the book actually listed places to get them fixed or replaced! It was amazing how much practical information theythe Ivy League university) “My eldest graduates from Standford in June, so I’m optimistic she won’t fall into my footsteps,” Gates joked.Gates said he and his wife have been quite deliberate about the 1970s “Love and Logic” parenting model they’ve used to raise their three children, who are now 15, 18, and 22 years old, the core idea of the model is centered on the idea that applying emotional control, essentially minimizing emotional reactions like shouting kids. “One of the greatest benefits of the model is that it helps us learn how to keep a tighter control on our emotions and on our tongues,” co-founder Charles Fay wrote in a blog post. Gates admits he and his wife haven’t been perfect at carrying out the approach. “Can you get rid of the emotion? You can’t totally do it.” He said.Apart from holding hot-blooded parent tempers, the love and logic model also stresses the importance of not leaning into rewards for kids, but instead demonstrating unconditional love and admiring kids for who they are, not what they do (or don’t) achieve. Fay wrote on his site. “What’s most important is that our children develop good character, curiosity, and problem-solving skills.The model is a bit like the Socratic method, in that it pushes parents to focus on asking questions of their kids and getting them to think about how to solve their own problems, instead of feeding them answers.24. What can we infer about Gates’s children?A. They were given an honorary diploma.B. They have graduated from the college.C. The eldest one hasn’t finished her study in college.D. They didn’t take math and computer science courses.25. How do Gates and his wife teach their children?A. In an unintended way.B. In a rude way like shouting.C. By applying the “Love and Logic” parenting model.D. By rewarding their children for their good performance.26. What do we know about the “Love and Logic” parenting model in Para. 2?A. It’s widely used to raise children.B. One of its functions is to command temper.C. It is the best approach to help parents teach their children.D. Gates regards it as the most effective way to get rid of the emotion.27. What’s the author’s attitude to the model?A. objectiveB. approvingC. opposedD. doubtfulCFinding fruits and vegetables at your typical grocery store that have been grown without the extensive use of pesticides(农药) can be difficult. Fortunately, The Environmental Working Group(EWG) has done all of the work for you in finding healthy and pesticide-free produce.EWG has created the 2018 Shopper's Guide to Pesticides in Produce, which helps shoppers to find unpolluted produce. Many consumers do not realize that pesticide residues(残留) are very common on traditionally grown produce products, even after they have been washed or peeled. Because of this, EWG has created their series of guides to lead consumers to safer food choices.In order to create these guides, EWG analyzed the USDA pesticides tests, which found a total of 230 different pesticides and pesticides breakdown products on thousands of produce samples. Analyzing this information, EWGobserved the big differences of the amount of pesticides found from product to product.The guide's two lists highlight the cleanest and dirtiest produce concerning pesticides. These two lists, Dirty Dozen and Clean Fifteen, show consumers how certain foods continue to carry trace amounts of pesticides with them to the grocery store shelves, while others make it to your kitchen almost pesticide-free.Some of the highlights from their analysis included the following findings:· More than one-third of strawberry samples analyzed in 2016 contained 10 or more pesticide residues and breakdown products.· Spinach(菠菜) samples had, on average, almost twice as much pesticide residue by weight compared to any other crop.· No single fruit sample from the Clean Fifteen tested positive for more than four pesticides.Only 25 years ago, the National Academy of Sciences raised concerns about exposure to poisonous pesticides in our food, yet consumers still consume a mixture of pesticides every day in America.28. Why did EWG create the 2018 Shopper's Guide to Pesticides in Produce?A. To warn some food companies.B. To advertise organic produce.C. To help consumers make safer choices.D. To analyze the USDA pesticides tests29. What is the result from the analysis of the USDA pesticides tests?A. 230 pesticides are banned.B. All the samples are polluted.C. All strawberries are poisonous.D. Pesticide amounts vary in products.30. Where are shoppers most likely to find spinach?A. Safer food list.B. Dirty Dozen list.C. Clean Fifteen list.D. Organic food advertisement.31. What can be inferred from the passage?A. All tradiyional produce is safe.B. Produce safety remains a problem.C. Consumers never worry about pesticides.D. No pesticides were used on crops 25 years ago.DIn 1949 when the People’s Republic of China was founded, only 117,000 students were attending colleges or universities. But the number soared to 37 million in 2015---the world’s largest student population. Now, one in every five college students is in China, according to the country’s first quality report on higher education, which was released by the Ministry of Education on Thursday.China’s higher education system, one of the largest in the world, has evolved quickly and contributed greatly to the country’s development in the past seven decades, the report said.The report also shows that cost on higher education has increased greatly in recent years---as has the number of educators and teaching resources.“The fast development of higher education in China has offered more ordinary Chinese people the opportunity to attend college. It has also provided intelligent support for the dramatic transformation of Chinese society,” said Wu Yan, director of the Higher Education Evaluation Center.”Colleges and universities are playing increasingly important roles in the country’s efforts to innovate(创新).”But the report also found that China’s higher education system has problems to overcome. It mentions a low transfer rate for scientific research achievements, inadequate education in the fields of innovation and a phenomenon that gives more weight in educators’ research success than to their teaching ability.“To improve China’s higher education, reforms should be continued, more resources should be allocated(分配) and advanced educational ideas should be introduced to create a good learning atmosphere and to cultivate students’ innovative abilities.32. Which of the following can serve as the best title for the news report?A. China has 1 in 5 of all college students in the world.B. Expense on higher education has increased greatly.C. China’s universities try to catch up with world-class universities.D. Advanced educational ideas should be introduced to China’s universities.33. What can we know from the report about China’s higher education system?A. It tells us the system can greatly benefit students’ innovative abilities.B. It says the system emphasizes the educators’ teaching ability.C. It speaks of a low transfer rate for scientific achievements.D. It mentions adequate education in the field of innovation.34. Para.4 mainly tells us_______.A. more ordinary Chinese people have the opportunity to attend collegeB. the benefits of the fast development of higher education in ChinaC. China’s efforts to innovate and the advantages innovation brings aboutD. the dramatic transformation of Chinese society35. The underlined word “cultivate” in the last Para. can be replaced by_________.A. burdenB. trustC. analyzeD. develop 第二节(共 5 小题,每小题 2 分,满分 10 分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。
