 Although it may come as a surprise to many people, postal services have existed in some parts of the world for thousands of years. There is ample evidence that a postal services existed among the Assyrians and Babylonians. In China a regular postal service was established in the seventh century BC, and over the centuries attained such a high level of efficiency that some 2000 years after its (24) _______ it won the admiration of travelers like Marco Polo. Efficient and highly developed postal services were also established in the Persia and Roman Empires. In ancient times, these services were mainly confined to the use of representative of the state; private citizens made use of slaves, merchants and the (25) _______ to send their messages and documents. In Medieval Europe, postal services were organized by emperors and by the papacy, (26) _______ private citizens continued to entrust their correspondence to various travelers. Later around the 13th century, universities and towns came to have the own messengers. However, it was not until the 14th century when merchants, the private citizens who had the greatest need for a speedy and regular exchange of correspondence, began to set (27) _______ regular courier services. The needs of business (28) _______ to the development of the postal services as we know it today.

Question 27: 

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks from 31 to 35:

In Part Three of the Speaking Section you work together with a partner. You have to do a single task which usually lasts about 3 minutes. One possible task is “problem solving”, which means you have to look at some visual information and then (31)__ the problem with your partner. You may be shown photos, drawings, diagrams, maps, plans, advertisements or computer graphics and it is (32)__ that you study them carefully. If necessary, check you know exactly what to do by politely asking the examiner to (33)__ the instruction or make them clearer. While you are doing the task, the examiner will probably say very (34)__ and you should ask your partner questions and make suggestions if he or she is not saying much. If either of you have any real difficulties, the examiner may decide to step in and help. Normally, however, you will find plenty to say, which helps the assessor to give you a fair mark. This mark depends on your success in doing the task by (35)__ with your partner, which includes taking turns in giving opinions and replying appropriately, although in the end it may be possible to “agree to disagree”.

Question 32: 

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:

The changing profile of a city in the United States is apparent in the shifting definitions used by the United States Bureau of the Census. In 1870 the census officially distinguished the nation’s “urban” from its “rural” population for the first time. “Urban population” was defined as persons living in towns of 8,000 inhabitants or more. But after 1900 it meant persons living in incorporated places having 2,500 or more inhabitants.

Then, in 1950 the Census Bureau radically changed its definition of urban to take account of the new vagueness of city boundaries. In addition to persons living in incorporated units of 2,500 or more, the census now included those who lived in unincorporated units of that size, and also all persons living in the densely settled urban fringe, including both incorporated and unincorporated areas located around cities of 50,000 inhabitants or more. Each such unit, conceived as an integrated economic and social unit with a large population nucleus, was named a Standard Metropolitan Statistical Area (SMSA).

Each SMSA would contain at least (a) one central city with 50,000 inhabitants or more or (b) two cities having shared boundaries and constituting, for general economic and social purposes, a single community with a combined population of at least 50,000, the smaller of which must have a population of at least 15,000. Such an area would include the county in which the central city was located, and adjacent counties that were found to be metropolitan in character and economically and socially integrated with the county of the central city.By 1970, about two-thirds of the population of the United States was living in these urbanized areas, and of that figure more than half were living outside the central cities.

While the Census Bureau and the United States government used the term SMSA (by 1969 there were 233 of them), social scientists were also using new terms to describe the elusive, vaguely defined areas reaching out from what used to be simple “towns” and “cities”. A host of terms came into use: “metropolitan regions”, “poly-nucleated population groups”, “conurbations”, “metropolitan clusters”, “megalopolises” and so on.

Question 34: The word “those” in paragraph 2 refers to _______.         

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:

Under certain circumstances, the human body must cope with gases at greater-than-normal atmospheric pressure. For example, gas pressures increase rapidly during a drive made with scuba gear because the breathing equipment allows divers to stay underwater longer and dive deeper. The pressure exerted on the human body increases by 1 atmosphere for every 10 meters of depth on seater, so thay at 39 meters in seawater a diver is exposed to pressure of about 4 atmosphere. The pressure of the gases being breathed must equal the external pressure applied to the body, otherwise breathing is very difficult. Therefore all of the gases in the air breathed by a scuba diver at 40 meter are present at five times their usual pressure. Nitrogen, which composes 80 percent of the air we breathe, usually causes a balmy feeling of well-being at this pressure. At a depth of 5 atmosphere, nitrogen causes symptoms resembling alcohol intoxication, known as nitrogen narcosis. Nitrogen narcosis apparently results from a direct effect on the brain of the large amounts of nitrogen dissolved in the blood. Deep dives are less dangerous if helium is substituted for nitrogen, because under these pressures helium does not exert a similar narcotic effect. As a scuba diver descends, the pressure of nitrogen on the lungs increases. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues. The reverse occurs when the diver surfaces, the nitrogen pressure in the lungs falls and the nitrogen diffuses from the tissues into the blood, and from the blood into the lungs. If the return to the surface is too rapid, nitrogen in the tissues and blood cannot diffuse out rapidly enough and nitrogen bubbles are formed. They can cause severe pains, particularly around the joints. Another complication may result if the breath is held during ascent. During ascent from a depth of 10 meters, the volume of air in the lungs will double because the air pressure at the surface is only half of what it was at 10 meters. This change in volume may cause the lungs to distend ang even rupture. This the rise of the exhaled air bubbles, and must exhale during ascent.
