1．二进制数1011．11的等值十进制为______。

正确答案：11．75解析：1011．11=1×23+0×22+1×21+1×20+1×2-1+1 ×2-2=11．751011．11=1×23+0×22+1×21+1×20+1×2-1+1 ×2-2=11．75@【相关知识点】@进制转换(1)二、八、十六进制转为十进制：按权展开即可，注意小数点问题。

例如：11011100．101B=1×27+1×26+0×25+1×24+1×23+1×22+0×21+0×20+1×2-1+0×2-2+1×2-3。

=128+64+16+8+4+0．5+0．125=220．6251600=1×82+6×81+0×80=64+48=112A10 B．8H=10×163+1×162+0×161+11×160+8×16-1=40960+256+11+0．5=41227．5(2)十进制转为其他进制10→2：整数部分除2取余，倒序排列；小数部分乘2取整，正序排列，最后合并两部分即可。

例如：将十进制整数98转化为二进制整数，过程如下：十进制转二进制的横式：98=2×49+0=2×(2×24+1)+0=2×(2×(2×(2×6+0)+0)+1)+0=2×(2×(2×(2×(2×3+0)+0)+0)+1)+0=2×(2×(2×(2×(2×(2×1+1)+0)+0)+0)+1)+0=2×(2×(2×(2×(2×(2×(2×0+1)+1)+0)+0)+0)+1)+0注：直到最内侧括号内的乘数变为0时，运算结束，可得出98=1100010B。

There are 4 tasks for you to fulfill. Y ou should read this materials carefully and do the tasks as you are instructed.Task 1In ancient times the most important examinations were spoken, not written. In the schools of ancient Greece and Rome , testing usually consisted of saying poetry aloud or giving speeches.In the European universities of the Middle Ages, students who were working foradvanced degrees had to discuss questions in their field of study with people who had made a special study of the subject. This custom exists today as part of the process of testing candidates for the doctor's degree.Generally, however, modern examinations are written. The written examination, where all students are tested on the same question, was probably not known until the nineteenth century. Perhaps it came into existence with the great increase in population and the development of modern industry. A room full of candidates for a state examination, timed exactly by electric clocks and carefully watched over by managers ,resembles a group of workers at an automobile factory. Generally, during examinations teachers and students are expected to act like machines.One type of test is sometimes called an "objective" test. It is intended to deal with facts, not personal opinions. To make up an objective test the teacher writes a series of questions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like correct answers to students who have not learned the material properly.51. In the Middle Ages students_________.A.took objective testsB.specialized in one subjectC.were timed by electric clocksD.never wrote exams52. The main idea of paragraph 3 is that_________.A.workers now take examinationB.the population has grownC.there are only written examsD.examinations are now written and timed53. The kind of exams where students must select answers are_________.A.personalB.spokenC.objectiveD.written54. Modern industry must have developed_________.A.before the Middle AgesB.around the 19th centuryC.in Greece or RomeD.machines to take tests55. It may be concluded that testing_________.A.should test only opinionsB.should always be writtenC.has changed since the Middle AgesD.is given only in factoriesTask 2Adam Smith was the first person to see the importance of the division of the labor. He gave us an example of the process by which pins were made in England."One man draws out the wire, another strengthens it, a third cuts it, a fourth points it, and a fifth gives it a head. Just to make the head requires two or three different operations. The work of making pins is divided into about eighteen differentoperations, which in some factories are all performed by different people, though in others the same man will sometimes perform two or three of them.Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4800 pins a worker. But if all of them had worked separately and independently without division of labor, they certainly could not have made twenty pins in a day and not even one.There can be no doubt that division of labor is an efficient way of organizing work. Fewer people can make more pins. Adam Smith saw this, but he also took it for granted that division of labor is itself responsible for economic growth and development and it accounts for the difference between expanding economies and those that stand still. But division of labor adds nothing new, it only enables people to produce more of what they already have.56.According to the passage, Adam Smith was the first person to__________A. take advantage of the physical laborB. introduce the division of labor into EnglandC. understand the effects of the division of laborD. explain the bad causes of the division of labor57.Adam Smith saw that the division of labor__________A. enabled each worker to design pins more quicklyB. increased the possible output per workerC. increased the number of people employed in factoriesD. improved the quality of pins produced58.Adam Smith mentioned the number 4800 in order to__________A. show the advantages of the old labor systemB. stress how powerful the individual worker wasC. show the advantages of the division of laborD. stress the importance of increased production59.According to the writer, Adam Smith's mistake was in believingthat the division of labor__________A. was an efficient way of organizing workB. was an important development in methods of productionC. finally led to economic developmentD. increased the production of existing goods60.According to the writer, which one of the following is NOT true?A. Division of labor can enable fewer people to make more pins.B. Division of labor helps people to produce more of what they already have.C. Division of labor is by no means responsible for economic growth.D. Division of labor is an efficient way of organizing work.Task 3A new poll shows that people believe that computers and the Internet have made life better for Americans, but people also see some dangers in the trend toward computerization.The poll found that the public favors some government protection fromcyber-problems, but in general people are not essentially concerned with issues such as information overload or the never-ending flow of phone calls, faxes and e-mails. A separate survey of children aged 10-17 shows that they have a more positive attitude about computers than adults do, and most have made use of up-to-date technology in their schools.The survey found that enthusiasms for computers and the Internet is found in all income groups, all regions of the country, all races, and most age groups. However, people over 60 and those toward the lower end of the income rank tend to show lower rates of computer ownership and Internet usage. The survey shows that “some kind of gap has been crossed: computers are part of everyday life for most Americans, and the Internet is close behind.”61.The first paragraph shows thatA. the new poll about computers and the Internet is helpfulB. people should explore the dangers of computerizationC. people can not do without computers and the InternetD. computerization has its advantages and disadvantages62.The word “enthusiasm” is closest in meaning toA. great loveB. great hatredC. problemD. advantage63.What are the Americans concerned about according to the poll?A. Age of children using the InternetB. Government protection from the Internet problemsC. Information overloadD. The flow of phone calls, faxes, and e-mails.64. American adults tend to than teenagers.A. care more about information overloadB. like using computers moreC. dislike using computers moreD. face less danger65. We can learn from the passage thatA. all the American children have used the latest technology in schoolsB. computers and the Internet are very popular with AmericansC. Americans tend to place more importance in the Internet usage than computersD. the public in America do not hate the Internet problemsTask 4Directions: After reading it, you should give brief answers below it (numbered 66 through 70). Y ou should write your answers briefly (in no more than 4 words) after the corresponding numbers.This autumn term, spring term, or academic year program offers advanced students an opportunity to improve their spoken and written Chinese, and to be familiar with a range of people and organizations that are helping to shape China’s relationship with the United States and the world.
