Unluckily , the theatre is on the other side of the town , and the bus service(服务) between my office and Richland Hills is not very good . But if you are lucky, you can make the round trip in 45 minutes .Last Monday , I stood at the bus stop for fifteen minutes waiting for the bus . By the time I saw one come around the corner , there was not enough time left to make this trip . So I gave up and went back to the office . The same thing happened on Tuseday , and again on Wednesday . On Thursday , my luck changed . I got on a bus right away . When I got there , however , I found a long line of people at the box office .I heard one man say I would not have enough time in line for over an hour . I knew I would not have enough time to wait in a line . I caught the next bus and went back across the town . By Friday I decided to make the trip by taxi , it was expensive , but I felt the concert would be worth hearing . The trip by taxi only took 10 minutes , but it felt like an hour to me .

When the family is large , one of the cars is sold and they will buy a van(房车) .A small car can hold（容纳）four persons and a large car can hold six persons but it is very crowed .

2003年安徽省申论真题及参考答案(统编)
2003年安徽省申论真题及参考答案满分：100分时限：120分钟题号 1 2 总分累分人复核人得分一、注意事项1.申论考试是对应考者阅读理解能力、综合分析能力、提出和解决问题能力、文字表达能力的测试。
2.作答参考时限：阅读资料30分钟，作答90分钟。
3.仔细阅读给定资料，按照后面提出的“申论要求”依次作答。
二、给定资料1.2002年全国高校毕业生中，约有45万大学生未能在毕业后马上落实就业单位。
根据现有的数据预测，如果就业状况没有太大改变，2003年将有至少60万人不能很快走上工作岗位。
2.一些用人单位的人事负责人认为，许多学生动手能力差，招来后，还要花费相当的精力进行培训，不能很快开展工作。
记者在广东、上海等地的人才招聘会上看到，相当多的用人单位只招聘具有两年以上工作经验的大学生。
面对用人单位的这些条件，许多大学生满怀希望而来，沮丧失望而去。
他们往往愤愤不平地强调：“大学生的本职是读书”，招聘单位提出这些要求“太没道理！”3.在武汉一家人才市场，上海某生物技术公司上海地区的招聘人员不停地招呼：“想到上海工作的，请到这边来。
”但很久都无人投档。
而该公司的武汉地区招聘台却被求职者围得水泄不通。
应聘的大学生认为，在本地就业，关系多，环境熟，生活有父母照顾。
面对保险、广告、咨询、法律服务等一批新兴行业，一些大学生坦言，这些行业保障度低，虽然行业整体利润高，但是风险大，说不定我们进去干不了几年，就要第二次择业。
4.往年“炙手可热”的英语专业毕业生，已不再是市场的“抢手货”。
近来，很多单位不再招聘专门英语人才，而只是把英语作为一个附加条件。
如一家单位的招聘主管说：“我们公司和外商谈判时，并不需要非常专业的英语水平。
如招聘市场经理这一职位时，我们要求英语水平达到六级以上，这样，一举两得，翻译和销售人员都有了。
”5.人才市场招聘的实际情况表明，性格活泼、反应敏捷、口才好的大学生往往能很好地推介自己，占尽优势。

They are especially afraid of large, hairy ones.The largest and most frightening of all spiders is the bird-eating spider, which lives in the hot, thick rain forests of northern South America.Bird-eating spiders are a type of tarantula (狼蛛). They can bite, and the bite is painful, but it will not kill a grown-up. The poisonous bite of a black widow spider is far more dangerous.Bird-eating spiders often hide in holes and under rocks during the day, but at night they creep out and hunt for insects. As you might guess from their name, they also catch birds and eat them.They have another unusual ability. They can walk up windowpanes (玻璃窗) because of sticky, silky hairs on their feet that cling to glass.46.

He grew up in the banks of the Mississippi River and used the pen nameof “Mark Twain”. The two novels brought him his greatest fame: Toni Sawyer and Huckleberry Finn. Another book, Life on the Mississippi, told of his adventures on the river boats of the period.It was during the Civil War that Mark Tw ain‟s life as a writer started. At that time he was working as a newspaper man in Nevada and California. His short story, The Celebrated Jumping Frog of Calaveras County, was an immediate success and his new life began.In 1870, Mark Twain married Olivia Langdon. He had fallen in love with his wife even before he met her. His wife had a greet influence on Twain‟s later books.Mark Twain was also a very successful lecturer. His travels around the country giving talks on different kinds of subjects helped make him famous and increased the sale of his books.Tom Sawyer and Huckleberry Finn are considered Twain‟s best works. They are marked by humor and satire （讽刺文学，讽刺）and provide his readers with an excellent picture of his time. His last book was completed in 1909, one year before his death. He was then 74 years old.51.

However, in primitive societies a system of barter was used. Barter was a system of direct exchange of good. Somebody could exchange a sheep, for example, for anything in the market place that he or she considered to be of equal value. Barter, however, was a very unsatisfactory system of exchange, and various money systems developed based on goods that the members of a society recognized as having value. Cattle, grain, teeth, shells, salt, and tobacco had all been used. Precious metals gradually took over because, when made into coins, they were portable, durable, recognizable, and divisible into larger and smaller units of value.A coin is a piece of metal, usually disc-shaped, which bears lettering, designs or numbers showing its value. Until the eighteenth and nineteenth centuries, coins were given monetary worth based on the exact amount of metal contained in them, but most modern coins are based on face value—the value that the governments choose to give them, which doesn‟t show the actual metal content. Coins have been made of gold, silver, copper, plastic and in China even from tealeaves. Most governments now issue paper m oney in the form of bills, which are really “promises to pay”. Paper money is obviously easier to handle and much more convenient in the modern world. Checks and credit cards are being used increasingly, and it is possible to imagine a world where “money” in the form of coins and paper currency will no longer be used. Even today, in the United States, many places, especially filling stations will not accept cash at night for security reasons.56. “Barter” (Line 2, Paragraph l) here means.A. exchanging goods for moneyB. exchanging goods for goodsC. exchanging a sheep for anything in the marketD. exchanging money for goods57. Why were precious metals gradually used for making coins?A. Because they were durable and portable.B. Because they were recognizable.C. Because they were divisible.D. All of the above.58. Coins were given value according to the exact amount of metals contained in them .A. before the eighteenth and nineteenth centuriesB. after the eighteenth and nineteenth centuriesC. during the eighteenth and nineteenth centuriesD. between the eighteenth and nineteenth centuries59. “Promises to pay” (Line 6, Paragraph 2) means.A. possibilities to payB. necessities to payC. obligations to payD. opportunities to pay60. A world without any money in the form of coins and paper is .A. suitableB. possibleC. necessaryD. avoidableTask 4 (3 points each; 15 points in all)Directions: This task is the same as Task l (No.61 through No.65).In most lectures, several main ideas are presented. These are the concepts（思想）the lecturer wants the students to remember. Often the lecturer has a general idea that serves as an “umbrella” covering the other main concepts. The students' job, then, is to pick out the main concepts, including the “umbrella” idea.Lecturers usually begin with an introduction. Sometimes the main concepts and the “umbrella” idea are briefly presented in the introduction; often they are not. Next comes the body of the lecture. It is here that the several main concepts are always presented. The final part of a lecture, the conclusion, is traditionally a summary of the main concepts. This is alsothe place where the “umbrella” idea can most easily be repeated, restated, or even introduced for the first time.When a lecture is well organized, with a clear-cut beginning, middle and end, the main ideas are usually easy to pick out. When a lecture is not well organized, getting the gist of what is being said is quite difficult. Some lecturers are “long-winded”, taking a long time to come to the point.Others ramble on (杂乱地漫谈) and never seem to come to the point at all.61.
