Questions 21 to 30 are based on the same passage.
Understanding American Education
American education offers a rich field of choices for the international students. In order to make informed decisions, a student will need to know how the US education system is organized. Let's start by examining the educational structure.
Primary and Secondary School
Around age six for US children, they attend five or six years of primary school. Next they go to secondary school, which consists of either two three-year programs or a three-year and a
four-year program. These are called "middle school" or "junior high school" and "senior high school" (often just called "high school"). Americans call these 12 years of primary and secondary school the first through 12th "grades".
Higher Education
After finishing high school (12th grade), US students go on to college or university. College or
university is known as "higher education".
State College or University. A state school is supported and run by a state or local government. Each of the 50 US states operates at least one state university and possibly several state colleges.
Private College or University. These schools are operated privately, not by a branch of the government. Tuition will usually be higher than that at state schools. Often, private colleges and universities are smaller in size than state schools.
Two-year College. A two-year college admits high school graduates and awards an Associate's Degree. Some two-year colleges are state-supported, or public; others are private. Two-year college or "junior" college graduates usually transfer to four-year colleges or universities, where they complete the Bachelor's Degree in two or more additional years.
Community College. This is a two-year, or public college. Community colleges serve a local community, usually a city or county. Many of the students are commuters who live at home, or evening students who work during the day. Often, community colleges welcome international students. Many of these schools offer special services to international students such as free tutoring. Many community colleges also offer ESL or intensive English programs. Some community colleges provide housing and advising services that an international student might need.
Institute of Technology. This is a school that offers at least four years of study in science and technology. Some institutes of technology have graduate programs. Others offer shorter courses.
Technical Institute. A technical institute trains students in fields such as medical technology or industrial engineering. Although the course may prepare you for the career you want, the degree may or may not be equivalent to a college or university degree. Some colleges and universities do not accept credits from students who have attended technical institutes and want to transfer.
Church-related School. Many US colleges and universities were founded by religious groups. The relationship, however, between the school and the religious organization may be very flexible. Sometimes, these schools prefer to admit students who are members of the sponsoring religious group. Nearly all these schools welcome students of all religions and beliefs. Traditionally, many church-related schools have required that students take Bible courses and attend chapel services. But these practices are becoming less common.
Course of study of Undergraduate Years
"Freshmen" and "sophomores" are known as "underclassmen". "Juniors" and "seniors" are known as "upperclassmen".
Each student is assigned a faculty advisor who teaches courses in the student's major field. This advisor helps the student select a program of study. An international student will also have an international student advisor. This person helps the international students adjust to US life,
handles visa and other paperwork problems, and organizes activities for international students.
Classroom Learning of Undergraduate Years
Classes range from large lectures for several hundred students to smaller classes and seminars with only a few students. Professors usually assign textbooks and other readings each week. They also require several written reports each semester. Students will be expected to keep up to date with the required readings in order to join in class discussions and to understand the lectures. Science students are also expected to spend time in the laboratory.
Academic Year of Undergraduate Years
The school calendar usually begins in August or September and continues through May or June. It is a good idea for international students to enter US universities in autumn. Also, many courses are designed so students will take them in sequence, starting in autumn and continuing through the year.
The academic year at many schools is composed of two terms or semesters. Other schools use a three-term calendar known as the "trimester" system. Still others divide the year into the "quarter" system of four terms, including a summer session which is optional.
Credits and Marks
Each course is considered to be worth a number of "credits" or "credit hours". This number is roughly the same as the number of hours a student spends in class for that course each week. A course is typically worth three to five credits. A full program at most schools is 12 or 15 credit hours (four or five courses per term). International students are expected to enroll in a full program during each term.
Professors give each student a mark or "grade" for each course. The marks are based upon classroom participation, one or more research or term papers, or laboratory reports, possible short exams or quizzes and final exams.

Part 4 Multiple choices
(Each item: 1)
Directions:Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D.
Questions 31 to 35 are based on the same passage.
You finally graduated from high school and you are either looking forward to your first semester in college or already there. Your parents are telling you how important it is to study and stay focused, but we all know what you are really looking forward to, having a good time! College is definitely something you have to take serious, after all, your future depends on it, but you also need to have a good time and learn how to live life a little bit. This means having college fun, college life and of course college parties!
College Life is probably going to be your first experience away from home for any long period of time. You will probably still have mom and dad feeding you money, but you are going to be responsible for every other aspect of your life. Mom won't be doing your laundry and cleaning up your room anymore. The bright side of that is that you won't have the parental units hanging over your shoulder every five minutes or wanting to know where you were until two in the morning either. College life definitely has its perks.
You are going to make a ton of new friends too. You are going to be exposed to students from all different life styles and backgrounds. The beauty of dorm life is that you can have people living
with each other and becoming friends that would probably never happen in any other setting. You may be from a normal middle class neighborhood and your roommate could be the son of a millionaire. It makes for some very interesting times.
The more serious aspect of college life is dealing with legitimate stress for the first time in your life. You are going to have to learn balance and this is not always easy. You are going to be exposed to the possibility of having a good time all the time and you are going to have to remain disciplined. There is also, of course, the exam schedules. Tests and homework are going to get your blood pressure up a bit, but just stay organized and budget out your time between studying and play time and you will be fine. Not what you may want to hear, but at times you are going to have to act like an adult. Okay, enough of that serious stuff, let's get to the good stuff about college life!

Questions 36 to 40 are based on the same passage.
There's no need to be lonely when you reach your chosen university or college—join one of the many clubs or societies on offer and you are sure to make friends quickly. The major benefit of joining them is that whether you choose to join a society or club because it will introduce you to people who share your interests, or to try something new, it is a great way to start your life in the UK.
The students union is the place to search for these new experiences. Student-run societies offer a variety of interests and activities—from groups based on common nationality or religion, to leisure and matters that are more academic. There will also be a range of sports clubs on offer, from football to hockey (曲棍球) to table tennis. Not only will joining a sports club help you make friends, it will help your understanding of British culture, both on and off the playing field. Sports clubs offer an exciting social life for their teams, from club events after a match to going on an international tour to play abroad. Sports nights at the students union are generally the busiest nights, wherever you are studying.
Every university or college over here has a great selection of clubs and societies for you to choose from. Many cultural societies have links with other universities, or even national networks, meaning you get a chance to mingle with people you share an interest with that you wouldn't usually get the chance to meet.
So make sure you check out what's on offer, either by attending the Freshers' Fair or looking in the
students union handbook, which lists what societies are on offer, and which is available from your university or college union. Some university websites also offer links to their societies and clubs, so it is a good idea to check them out too. If you cannot find one that interests you, there will be plenty of support to start your own group. With a little effort, the benefits of joining a club or society will make your introduction to higher education in Britain easier and a lot of fun. After all, student life is not just about work!

Questions 41 to 45 are based on the same passage.
Given the lack of fit (匹配) between gifted students and their schools, it is not surprising that such students often have little good to say about their school experience. In one study of 400 adults who succeeded in all areas of life, researchers found that three-fifths of these individuals either did badly in school or were unhappy in school. Anecdotal (名人轶事) reports support this. Pablo Picasso, Charles Darwin, Mark Twain, Oliver Goldsmith, and William Butler Yeats all disliked school. So did Winston Churchill, who almost failed out of Harrow, a famous British school. About Oliver Goldsmith, one of his teachers remarked, "Never was so dull a boy." Often these children realize that they know more than their teachers, and their teachers often feel that these children are arrogant, inattentive, or unmotivated.
Some of these gifted people may have done poorly in school because their gifts were not scholastic (学术的). Maybe we can account for Picasso in this way. But most did poorly in school not because they lacked ability but because they found school unchallenging and consequently lost interest. Yeats described the lack of fit between his mind and school: "Because I had found it difficult to attend to anything less interesting than my own thoughts, I was difficult to teach." As noted earlier, gifted children of all kinds tend to be strong-willed and stubborn (固执的) and are likely to lead to conflicts with teachers.
When highly gifted students talk about what was important to the development of their abilities, they are far more likely to mention their families than their schools or teachers. A writing prodigy (神童) was taught far more about writing by his journalist father than his English teacher. High-IQ children had much more positive feelings about their families than their schools. About half of the mathematicians studied by Benjamin Bloom had little good to say about school. They all did well in
school and took honors classes when available, and some skipped grades.
41.The main point the author is making about schools is that ________________.
A. they should enroll as many gifted students as possible
B. they should organize their classes according to the students' ability
C. they are often incapable of meeting the needs of gifted students
D. they should satisfy the needs of students from different family backgrounds
42.The author quotes the remarks of one of Oliver Goldsmith's teachers ________________.
A. to show how poor Oliver's performance was at school
B. to illustrate the strong will of some gifted children
C. to explain how dull students can also be successful
D. to provide support for his argument
43.Pablo Picasso is listed among the many gifted children who ________________.
A. could not successfully cope with their studies at school
B. paid no attention to their teachers in class
C. contradicted their teachers much too often
D. behaved arrogantly in the presence of their teachers
44.Many gifted people said they succeeded because of ________________.
A. good school education
B. their education at home
C. their own hard work
D. their strong will
45.The root reason why many gifted students having bad memories of their school years is that
________________.
A. they were seldom praised by their teachers
B. school courses failed to inspire or motivate them
C. their talent brought them a lot of trouble
D. teachers were usually stricter than their parents

《市场营销》模拟试题1参考答案 班级：姓名：学号： 一、案例分析题 一、美国钟表公司通过市场营销研究发现，可把市场上的购买者分为三类： 第一类消费者希望能以尽量低的价格购买能计时的手表，他们追求的是低价位的实用品,这类消费者占23％。第二类消费者希望能以较高的价格购买计时准确、更耐用或式样好的手表，他们既重实用，又重美观，这类消费者占46％。第三类消费者想买名贵的手表，主要是把它作为礼物，他们占整个市场的31％。 于是,根据第一、二类消费者的需要，避开日本精工和西铁城名表，制造了一种叫做“天美时”的物美价廉的手表，一年内保修，而且利用新的销售渠道，广泛通过商店、超级市场、廉价商店、药房等各种类型的商店大力推销，结果很快提高了市场占有率，成为世界上最大的钟表公司之一。 单项选择：（每小题2分,共6分） 1．天美时公司采用什么样的市场细分标准将市场分为三种类型？（C ） A．地理环境细分 B．心理细分 C．购买行为细分 D．人口因素细分2．天美时公司选择了哪种目标市场策略？（B） A．差异性营销策略 B．集中性营销策略 C．无差异营销策略 3．天美时公司采用的是哪一种市场定位策略？（ A ） A．避强定位 B．迎头定位 C．重新定位 （8分） 比了下去？试用市场营销环境理论分析之。 答：（1）20世纪初期，汽车供不应求，竞争对手很少，福特公司凭借创建汽车生产流水线，以高效率、低成本赢得市场。20世纪20年代，汽车市场发生变化，竞争对手增多，汽车供应量增加，人们变得挑剔起来，不再是“企业生产什么，我就买什么了”。 （2）任何企业的活动都离不开营销环境。福特公司后来比通用公司比了下去的根本原因是忽视市场营销环境的变化，尤其是忽视顾客需求的变化，一意孤行地认为“不管顾客需要什么，我的车就是黑色的”。还有就是忽视对竞争对手的分析。而通用公司则针对福特公司的营销策略及“挑剔的顾客”推出“汽车形式多样化”,最大限度地满足顾客的需求，从而在市场上远远超过了福特公司。 三、有四家公司，其经营决策是：（8分） A公司生产手表，认为只要生产走时精确、造型优美、价格适中的名牌产品，即能获得经营成功。
