第4题：
Accounting is More Than Numbers
Accounting could date back to about 7,000 years ago. People of that time relied on old accounting methods to record the growth of crops and herds. Accounting has greatly developed with the growth of joint-stock companies.
When you think of accounting, you may find pages of tables and numbers. That image doesn't usually give you too much excitement. When you have your own business, though, those numbers come to mean the world to you because they give you the record of how much money you've earned or lost.
Actually, accounting is not simply about strange dollar amounts or boring numbers; they're your sales figures, your costs, and your profits. In other words, accounting is a language of business. Once you know how to work with those numbers, how to read those numbers and how to read the story they tell, you will be able to manage your business toward greater success.

Text 1
In 1939 two brothers, Mac and Dick McDonald, started a drive-in restaurant in San Bernadino, California. They care fully chose a busy comer for their location. They had run their own business for years, first a theater, then a barbecue(烤肉 )restaurant, then another drive -in. But in their new operation, they offered a new, shortened menu: French fries, hamburgers, and sodas. To this small selection they added one new concept: quick service, no waiters or waitresses, and no tips.
Their hamburgers sold for fifteen cents. Cheese was another four cents. Their French fries and hamburgers had a remarkable uniformity, for the brothers had developed a strict routine for the preparation of their food, and they insisted on their cooks' sticking to their routine. Their new drive -in became incredibly popular, particularly for lunch. People drove up by the hundreds during the busy noontime. The serf - service restaurant was so popular that the brothers had allowed ten copies of their restaurant to be opened. They were content with this modest success until they met Ray Kroc.
Kroc was a salesman who met the McDonald brothers in 1954, when he was selling milkshake -mixing machines. He quickly saw the unique appeal of the brothers fast food restaurants and bought the right to franchise (特许经营other copies of their restaurants. The agreement struck included the right to duplicate the menu. The equipment, even their red and white buildings with the golden arches.
Today McDonald' s is really a household name. Its names for its sandwiches have come to mean hamburger in the decades since the day Ray Kroc watched people rush up to order fifteen - cent hamburgers. In 1976, McDonald' s had over $1 billion in total sales. Its first twenty - two years is one of the most incredible success stories in modem American business history.
21. This passage mainly talks about ______.
A) the development of fast food services
B) how McDonald's became a billion- dollar business
C) the business careers of Mac and Dick McDonald
D) Ray Kroc’s business talent

Finding a Job
At sixteen Ron Mackie might have stayed at school,but the future called to him excitedly.“Get out of the classroom into a job,”it said,and Ron obeyed.His father,supporting the dcci-sion,found a place for him in a supermarket.“You're lucky,Ron,”he said.“For every boy with a job these days,there's a dozen without.” So Ron joined the working world at twenty pounds a week.
For a year he spent his days filling shelves with tins of food.By the end of that time he was looking back on his school days as a time of great variety and satisfaction.He searched for an in-terest in his work,with little success.
One fine day instead of going to work Ron got a lift on a lorry going south.With nine pounds in his pocket,a full heart and a great longing for the sea,he set out to make a better way for him-self. That evening,in Bournemouth,he had a sandwich and a drink in a cafe run by an elderly man and his wife.Before he had finished the sandwich,the woman had taken him on for the rest of the summer,at twenty pounds a week,a room upstairs and three meals a day.The ease and speed of it rather took Ron's breath away.At quiet times Ron had to check the old man's arithme- tic in the records of the business.
At the end of the season,he stayed on the coast. He was again surprised how straightforward it was for a boy of seventeen to make a living.He worked in shops mostly,but once he took a job in a hotel for three weeks.Late in October he was taken on by the sick manager of a shoe shop. Ron soon found himself in charge there;he was the only one who could keep the books.Ron was able to take over the shoe shop because______.
A: he got on well with the manager there
B: he knew how to keep the accounts of the business
C: he had had experience of selling books
D: he was young and strong答案：B解析：本文第一段的第一句说到：罗恩（Ron）感到未来在向他召唤：“走出教室，找个工作”，于是他们遵从了这一召唤。因此我们可以了解到是他自己想要开始工作。
根据本文第一段，他的父亲支持这一决定，并帮助罗恩找到了一份工作。由此我们对父亲的态度是很明确的。
本文第二段提到罗恩对学校生活的留恋，想要提高自己对目前工作的兴趣未果。由此可以判断出他认为超市的工作枯燥(dull) 。
第三段说罗恩“longing for the sea”（向往大海），因此他是想在海边找个工作的。应注意C选项中的“unwell”指身体不舒服、有病，因而不选。
根据上下文判断词汇含义。此题关键在于对“keep the books”的理解，这里指罗恩负责打理鞋店的生意，因为只有他懂得如何管理账目。而选项B中的accounts即是账目的意思。 -

正确答案：C
解析：试题(71)分析：该题考查嵌入式操作系统的定义，嵌入式操作系统是在boot loader对嵌入式设备进行初始化引导启动后，管理运行在设备上的所有其他程序的软件。故C选择software符合嵌入式系统的定义，为该题的正确选项。
嵌入式操作系统是在引导装入程序(boot loader)对嵌入式设备进行初始化引导启动后，管理运行在设备上的所有其他程序的软件。嵌入式系统在实现应用程序的同时，能保证软件的存储空间和操作的时间满足一定的要求。嵌入式操作系统都较小，一般仅包含初始引导装入程序、操作系统内核、设备驱动程序和用于存储用户数据的文件系统。嵌入式系统与常见的操作系统在结构上非常相似，区分它们的主要因素有预安装设备、功能有限和仅执行特别设计的任务等。
试题(72)分析：该题考查嵌入式系统各个组成部分的功能定义，其中boot loader处于整个软件系统的底层，用于对硬件的初始化引导，相当于PC中的BIOS，故该题选项为D。
试题(73)分析：嵌入式系统在实现应用程序的同时，对软件的存储体积和操作的时间有一定的要求，故B选项storage符合对存储的定义，为正确答案。
试题(74)分析：嵌入式操作系统对程序运行的时间根据优先级的高低限定了时间，对其完成操作的时间进行了限制，保证这个系统的正常运行。故选项为A。
试题(75)分析：嵌入式操作系统中包含设备驱动程序和文件系统，后者用于对用户数据和其他文件的存储。故选择为C。 -

第18题：
Do you have any idea what you would like to be and do after graduation? A lot of people don′! begin thinking about careers until they reach junior or senior year, which, in my opinion, is too late.
When people are trying to decide what they want to do, it helps to know something they love. Ever since I was little, I′ve always been doing someone′s hair, make-up or nails, starting with Barbie dolls and progressing to humans. Over the years my family has really inspired me to do this and now I fix friends′ and family members′ hair for weddings, dances and other big events.
I have been thinking about what I would like to do for a career since middle school. I did some research and discovered that I might really enjoy being a cosmetologist, so I went to my hair stylist and asked her lots of questions about what it takes to reach her level and what she would recommend I do. I considered her advice and then did more research.
I used Aveda′ s website to get information on the Aveda Institute and what type of credit (贷款) I would need from high school to apply. I found their institute has three parts: theoretical knowledge, practical experience, and professional business-building skills. For the past few years, I have been looking at Aveda in more and more detail. This school not only offers cosmetology, but also massage therapy. I grew up in Minnesota (美国中北部的一个州), so I plan to apply to the institute in Minneapolis that several people have highly recommended. It helps students become "future industry leaders in hair care, skin care, makeup and total body wellness". It is affordable and everyone there is friendly and understanding.
Having done the groundwork and thinking about what I′d like to do after high school, I know that I will definitely pursue my dream of becoming a cosmetologist.
After reading the text, we can infer the author is interested in ___________.A.traveling abroad
B.service business
C.social activities
D.acting on the stage答案：B解析：推断题。根据文章最后一句话“I know that I will definitely pursue my dream of becoming a cosmetologist”，cosmetologist表示美容师，可知为服务行业。 -

Interview with Allan Gray
1. I was working for a multinational company in the early 1980s,and my brother asked me if I was interested in going into partnership with him to set up a language school.I'd always wanted to work for myself,and I was a bit fed up with working for someone else,so I said yes.Primarily, I wanted the freedom to make my own decisions,I wanted room to be creative,and also I wanted to be able to get the credit and keep the profits if we were successful.I was also happy to carry the can and take the blame if things went wrong.These things are not possible if you work as an employee in a large organization.
2. I had to borrow money to help start the business,but we were lucky because we also had some outside capital to put into the business.These days it can be really hard to persuade banks to lend money to people who want to start a company,so we were fortunate .It was fairly easy to set up the business,because we had a very clear idea of what we wanted to do.The problem was,all our preconceptions（预想）about what it would be like to run a business were wrong. We made lots of mistakes, and we almost went bankrupt（破产的）at the beginning. At one point, we only had two students in the school.
3. Far too long!We lost money for the first four years and,as I was saying,we nearly went out of business.It took quite a long time to start making profit. The best thing we did,though,was that we hired some really good people to work for us.In fact,some of those people are still work-ing for us,24 years later. Now we're doing well,but it was very risky at first.
4. One is financial constraint（约束）.It can be very tough. I think all small businesses have cashflow problems-it often takes a long time to get paid by your customers.The second big prob- lem is marketing. It takes a lot of funds to market your business,and you have to get your name known and build a reputation .But the biggest challenge is managing the people.All businesses are about people,and you have to learn how to deal with all kinds of people-and I think we've been extremely good at getting the best of our staff.Paragraph 3______
A:.Strategies in expanding a small business
B: Right people to run a business
C: Time-consuming experience of being successful
D: Challenges of running a business
E: Difficulties in starting the business
F: Reasons for working for oneself答案：C解析：本段主要讲述作者答应哥哥合伙创建语言学校并为自己工作的种种原因。因此F 项是本段大意。
本段主要讲述的是自己开业遇到的种种困难，跟预想的大相径庭，犯了许多错误，差点破产，并且只招到两个学生。因此E项是本段大意。
本段主要讲成功之前花费的时间，前四年一直亏损，甚至差点破产。故本题选C。
本段主要讲在经营学校的过程中遇到的挑战。故本题选D。
根据第一段的“I was also happy to carry the can and take the blame if things went wrong.”可知，如果你做出错误决定，你就必须为其承担责任。故选E。
根据第二段“These days it can be really hard to persuade banks to lend money to people who want to start a company...”可知，困难是劝银行把钱借出来。
从第三段可知，作者招到了很好的员工为其工作，并因此获得盈利。故本题选F。
第四段讲述了三个挑战：资金约束、经营、管理员工。故本题选B。 -
