For someone who is such an extraordinarily successful investor, Warren Buffett is recognized as a pretty ordinary guy. Born in Omaha, Nebraska, for more than 40 years Buffett has lived in the same gray house on Farnam Street that he bought for $31,500. He wears shabby suits, drives his own car, drinks Cherry Coke, and is more likely to be found in a Dairy Queen than a . four-star restaurant.
Looking back on his childhood, one can seethe knowledgeable businessman. Even as a young child, Buffett was pretty serious about making money. He used to go door-to-door and sell soda pop. He and a friend used math to develop a system for picking winners in horseracing. Later, he also worked at his grandfather’s grocery store. At the age of 11, Buffett bought his first stock(股票). When he was 14, Buffett spent $1, 200 on 40 acres of farmland in Nebraska and soon began collecting rent from a local farmer, Buffett wasn’t keen on going to college but ended up at Wharton at
the University of Pennsylvania—his father encouraged him to go.
Buffett’s investment strat egy mirrors his lifestyle and overall philosophy. He doe sn’t collect houses or cars or works of art, and he looks down on companies that waste money on so useless things, such as private dining rooms, and high-priced racing cars. He is a creature of habit—same house, same office, same city, same soda—and dislikes change. In his investments, that means holding on to “core holdings” such as American Express, Coca-Cola, and The Washington Post Co. forever.
21. What can we know about Warren Buffet from this passage?
A. He is a successful investor and looks ordinary.
B. He leads an ordinary life and drives his own expensive racing car.
C. He spent all his life in the same gray house on Farnam Street.
D. He prefers to have dinner in a four-star restaurant than in a Dairy Queen.
22. What is Buff ett’s investment strategy according to the passage?
A. Saving for rainy days.
B. Encouraging changes.
C. Holding on to famous international companies.
D. Never wasting money on unnecessary things.
23. Which of the following things would Warren Buffett be interested in?
A. Fantastic racing cars.
B. Works of art.
C. Private dining rooms.
D. Stock of Coca-Cola.

Technology is the collection of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific research. Technology can be the knowledge of techniques, processes, and the like.
The simplest form of technology is the development and use of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel helped humans to travel in and control their environment. Developments in historic times, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.
Dictionaries and scholars have offered a variety of definitions. The Merriam-Webster Learner’s Dictionary offers a definition of the term: “the use of science in industry, engineering, etc., to invent useful things or to solve problems “and” a machine, piece of equipment, method, etc. , that is created by technology. ”Ursula Franklin, in her 1989 “Real World of Technology” lecture, gave another definition of the concept; it is “practice, the way we do things around here. ”The term is often used to imply a specific field of technology, or to refer to high technology or just consumer electronics, rather than technology as a whole.
Technology can be most broadly defined as the things, both material and immaterial,
created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems. It is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator.
The word “technology” can also be used to refer to a collection of techniques. In this context, it is the current state of humanity’s knowledge of how to combine resources to produce desired products, to solve problems, ful6l1needs, or satisfy wants; it includes technical methods, skills, processes, techniques, tools and raw materials. When combined with another term, such as “medical technology” or“space technology,” it refers to the state of the respective fie ld’s knowledge and tools.
28. What’s the easiest form of technology?
A. The techniques used in the production of goods.
B. The use of science in industry and engineering.
C. The development and use of basic tools.
D. The knowledge of how to combine resources.
29. What’s the definition of Ursula Franklin about technology?
A. It is inventing useful things or solve problems.
B. It is practice, the way we do things around here.
C. It is a machine, created by technology.
D. It is tools and machines, used to solve real-world problems.
30. What does the underlined word “It” in paragraph 4 refer to?
A. Simple tools such as a crowbar or wooden spoon.
B. More complex machines such as a space station.
C. The application of mental and physical effort.
D. The technology used to solve real-world problems.
31. Which of the following can be the best title of the text?
A. The usages of technology.
B. The definitions of technology.
C. The applications of technology.
D. The contents of technology.
D
One of my all time favorite holiday destinations is the Gold Coast. With its beautiful beaches, mountain hinterland and theme parks, the variety from one location to another is fantastic! And it’s also important that it’s like a playground for my children.
The Gold Coast certainly offers something for every member of our family. We all love heading down to the beach for an early morning swim or surf. The beaches feature some of the softest golden sand and pumping waves, making them ideal for surfing. Safety is important, especially when I’m out with the kids, and I feel better knowing that lifeguards are continually on patrol(巡逻). The long coast also offer the perfect setting for a leisurely walk at sunset—a favorite activity of mine.
Then, of course, there’s the bargain- hunting in the city’s center. For shopping-goers, there are amazing shopping centers, boutiques and the usual chain stores. I always pick up loads of goodies at Pacific Fair.
“The Gold Coast is popular for its theme parks—Sea World, Warner Bros Movie World and Dream World. The seal and dolphin presentations at Sea World keep both children and adults on the edge of their seats as the sea creatures go through a series of complicated jumps, flips and rolls. It’s great entertainment and an educational window to the underwater world for the kids. Our kids also enjoy meeting the characters at Movie World and watching how real movies are made.
Night-time is equally fun , as we usually set off to find the best local restaurants and cafes. The mix of cultures and influences has given the Gold Coast a wide variety of choices, including modem Australian, Italian, Asian and seafood, although sometimes nothing beats fish and chips!
A visit to the Gold Coast in the Sunshine State is worthwhile and fun.
32. Why docs the author consider the Gold Coast as her ideal holiday destination?
A. There are a lot of shopping centers.
B. The whole family can have fun there.
C. It’s a safe and interesting place for kids.
D. The author can walk leisurely along the coast.
33. What does the underlined word “boutiques” probably mean?
A. Theme parks.
B. Beautiful parks.
C. Small shops.
D. Local restaurants.
34. What docs Paragraph 4 mainly talk about?
A. What the theme parks offer.
B. How popular the Gold Coast is.
C. Why kids love theme parks so much.
D. What people can do in the Gold Coast.
35. What makes night-time in the Gold Coast attractive for tourists?
A. The presentations.
B. Different entertainments.
C. The shopping centers.
D. Various choices.

remarks from Zavos came during a debate with Dr. Paul R. Billings.

2020届河南省洛阳市高三二练英语试题学校:___________姓名：___________班级：___________考号：___________ 一、阅读选择 Are you driven to create change in bettering kids’ futures? Here are a few options. Education Going after a career in education is sometimes overlooked. Yet teaching is an important path to creating change. You will educate the young minds responsible for the future. In addition to presenting basic school subjects, you can teach them to be leaders. You can motivate them to want to make a difference themselves. A caree r in education doesn’t have to mean leaching in a classroom. You can help them to learn in a way that works for them and be a friend to them as well. Social work As a social worker, you can directly change the lives of children in need as well advocate for services for drug abusers, family-violence survivors, mental-health patients, and more. You will provide them with the necessary resources to succeed and advise them through trauma (精神创伤), unemployment, education difficulties, addiction and poverty. Many social workers are associated with governmental agencies, but there are also jobs in schools, nonprofit organizations and hospitals. Child psychology Studying child psychology may lead to a career option. Psychologists can provide support for children with mental-health problems and give them a place to be open about their feelings. You may wish to become a school psychologist and guide children (and their parents) through the education system while dealing with mental illness or trauma. As a psychologist, you will help your patients find the source of trauma or stress and discover ways of reducing or removing the problem. You may even conduct your own research on new treatment methods. 1．Which educational concept does the author support? A．Working with stud ents’ group leaders. B．Teaching children according to their interests. C．Keeping teaching children in the classroom. D．Encouraging students to make a change themselves. 2．Who will social workers help most probably?

高二下学期期中考试总结 紧张的考前复习，压制神经的考试，下考场后的议论纷纷，有人欢喜有人忧。全县统考结束后顿时感受轻松了不少，暂且别去说考试成绩的好坏，至少这种感受让人感到发自心里的放纵。随后而来的便是对考试成绩的焦急等待和新一轮学习的开始...也许以我这次的考试成绩并别能说成是优异，能够说算个中等吧。但关于我个人来说这也是一具进步，尽管有几科成绩别尽人意。下面就仔细分析分析吧。 先说说英语和历史吧。总体来说进入高中以来我的英语成绩呈现直线下滑趋势，这次也毫别出意外的只考了87分。我很清晰的知道考低分的原因:寻常老师让默写单词时别写，让记语法时别记。一到考试的时候就开始发愁，特别是在做单项挑选题的时候，单词疑惑什么意思感受哪个选项都对，语法疑惑如何运用感受哪个选项基本上答案，结果惟独乱猜了，这次考试在这方面就吃了大亏了。历史这科自我感受依然挺简单的，因为上次考试还得了80多分呢，我想的是这次至少能够考85分的，结果特别完美的验证了一具词语:眼高手低。成绩下来只考了66分。尽管说这次全校历史成绩都有所下滑，但是得高分的依然有的。这次历史成绩给了我别小的打击，更何况老班是算是由历史老师，的确有点别给他面子了。寻常历史学的还挺卖劲的，对历史也是有浓厚的兴趣的，可考试怎么说是考试，后面的非挑选题都是基本上只得了一半的分，未来可得注意了。再说说政治吧。说句实话《日子与哲学》这一册的知识比较难理解，寻常的学习也不过死记，全然别太理解其中的含义，寻常做练习题也别注意总结，结果考试的时候后面的咨询答题都是是胡写的，想到哪一点就写哪一点，没有头绪没有要点。有因必有果:有两个大题别得分，有一大题只得了一分，在整张卷子上拉了将近30分，尽管挑选题做的还能够，但分数也都是定格了，只考了59分。看看分数再想想自己在课堂上的表现:睡觉，发呆...特别是老师说练习题的时候都是是别听的，以至于对张老师说的咨询题分析、做题思路都毫无印象，考试的时候为所欲为，乱答一气。如今终于知道自己有多笨了，真懊悔。 数学和语文成绩小有进步。语文就别用说了，数学可是个难题。说句实话，数学有25分的挑选题别是我自己做的，后面的大题自己苦心专研的。自认为很简单的，结果很别爽的有两道大题别得分。挑选题在别人的热心帮助下错了两道，还别错。事实上，这段时刻可没少在数学上下功夫，终于功夫别负有心人得了92分。语文得了115分，我最开心的是语文没有低于110分过，但成绩还有待更进一步。最后说说地理吧。事实上高一上学期学自然地理的时候，我的地理成绩依然一踏糊涂，但在这种极其惊险的事情下，我依然毅然挑选了文科。为了补瘸腿科，我对地理学习也分外的努力。高一下学期是人文地理，比较简单，渐渐的我的地理成绩也有所上升。事实上能有如此的成绩和地理老师和老师是分别开的。刚开始学习地理的时候我别敢向老师咨询题，也从来没有咨询过。高一下学期和老师开始带我们班地理之后这种事情才有所改变，渐渐的也就没有什么胆怯的了。时刻长了对地理也产生了浓厚的兴趣。这对我将来的学习产生了很大的妨碍。这次地理成绩还算理想，考了83分。我想这与我平时的训练是分别开的，特别是考试前对基础知识的复习和对往常做过的练习题的复习，但是挑选题错的太多，错了5道，都是好基本上寻常老师说过的，真别应该。总体上来说，这次考试题别算太难。但由于自己的粗心大意依然吃了很多亏。未来一定要注意。 别管如何样，这次考试差不多结束了，成绩的好坏也差不多成了定局。但它只能代表过去，别能对自己的以后做判决。这次考试给了我很大的启示，也让自己看到了自己的缺点与别脚，有了这次的考试经验，将来我一定注意改正自己在学习中的缺点，弥补自己的别脚，争取再创一具更好的成绩！ 命运如同手中的掌纹，不管再如何蜿蜒但终究在你手中。要知道，没有等出来的漂亮，惟独拼出来的辉煌！
