Question II : Read the passage and answer the questions bellow. (0.75 pts)
Paper was invented by the Chinese in the first century A.D. The art of papermaking took
700 years to reach the Muslim world and another 700 years to get to Britain.
Most paper is made from wood. When the trees are cut down, they are carried by land or
water to paper mills. Here they are cut up and the wood is broken up into fibers, mixed with
water and chemicals. This wood pulp is then dried up on a machine and made into paper.
Papermaking is an important British industry, and paper from Britain is exported to South
Africa, Australia and many other countries. Some of the wood used in British
papermakingindustry comes from trees grown in Britain, but wood is also imported from
other countries such as Norway. One tree is needed for every 400 copies of a forty-page
newspaper. If half the adults in Britain each day buy one daily paper, this uses up over
40,000 trees a day. Trees are cut down faster than they can be replaced, so there may be a
paper shortage before the year 2020.

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 from 1 to 10.

Reading to oneself is a modern activity which was almost unknown to the scholars of the classical and medieval worlds, while during the fifteenth century the term "reading" undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become commonplace.

One should be wary, however, of assuming that silent reading came about simply because reading aloud was a distraction to others. Examinations of factors related to the historical development of silent reading have revealed that it became the usual mode of reading for most adults mainly because the tasks themselves changed in character.

The last century saw a steady gradual increase in literacy and thus in the number of readers. As the number of readers increased, the number of potential listeners declined and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages and offices, where reading aloud would cause distraction to other readers.

Towards the end of the century, there was still considerable argument over whether books should be used for information or treated respectfully and over whether the reading of materials such as newspapers was in some way mentally weakening. Indeed, this argument remains with us still in education. However, whatever its virtues, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and periodicals for a specialised readership on the other.

By the end of the twentieth century, students were being recommended to adopt attitudes to books and to use reading skills which were inappropriate, if not impossible, for the oral reader. The social, cultural and technological changes in the century had greatly altered what the term "reading" implied.

Question 1: Reading aloud was more common in the medieval world because:

A. people relied on reading for entertainment

B. silent reading had not been discovered

C. there were few places available for private reading

D. few people could read to themselves

Question 2: The word "commonplace" in the first paragraph mostly means:

A. for everybody's use B. most preferable

C. attracting attention D. widely used

Question 3: The development of silent reading during the last century indicated

A. an increase in the average age of readers

B. an increase in the number of books

C. a change in the nature of reading

D. a change in the status of literate people

Question 4: Silent reading, especially in public places, flourished mainly because of:

A. the decreasing need to read aloud

B. the development of libraries

C. the increase in literacy

D. the decreasing number of listeners

Question 5 It can be inferred that the emergence of the mass media and specialized reading materials was an indication of .

A. a decline of standards of literacy

B. a change in the readers' interest

C. an alteration in educationalists ’attitudes

D. an improvement of printing techniques.

Question 6: The phrase "a specialized readership" in paragraph 4 mostly means:

A. a requirement for readers in a particular area of knowledge

B. a limited number of readers in a particular area of knowledge

C. a reading volume for particular professionals

D. a status for readers specialized in mass media

Question 7: The phrase “oral reader" in the last paragraph mostly means a person who:

A. is good at public speaking

B. practices reading to an audience

C. takes part in an audition

D. is interested in spoken language

Question 8: All of the following might be the factors that affected the continuation of the old shared literacy culture EXCEPT .

A. the inappropriate reading skills B. the specialized readership

C. the diversity of reading materials D. the printed mass media

Question 9: Which of the following statements is NOT TRUE according to the passage?

A. Reading aloud was more common in the past than it is today.

B. Not all printed mass media was appropriate for reading aloud.

C. The decline of reading aloud was wholly due to its distracting effect.

D. The change in reading habits was partly due to the social, cultural and technological changes.

Question 10: The writer of this passage is attempting to .

A. explain how reading habits have developed

B. change people's attitudes to reading

C. show how reading methods have improved

D. encourage the growth of reading.

EX: Read the passage, and choose the correct answer A, B, C or D for each question.

     For many of us, food isn't that important. However, for a few people, food is very improtant. For these people, meals are a kind of art.

     These people are interested in something called "haute cuisine" . Haute cuisine is French for "high cooking" . You can usually find haute cuisine in fancy French hotels anh high level restaurants.

     Haute cuisine has changed over the years, but the most important parst have remained the same. Haute cuisine meals are almost always very complicated, and they take a very long time to make. Usually, an haute cuisine meal has very many small dishes, instead of a few large ones. Also, with haute cuisine dishes, the appearance is very important. Of course, an haute cuisine dish must taste wonderful, but that is not enough. An haute cuisine dish must also look beautiful. Another very important part of haute cuisine is wine. Chefs and customers always try to select a wine that is a perfect match for their meal. The wine that people drink with haute cuisine is often very rare. You will not be surprised to hear that haute cuisine dishes are almost always very expensive.

     Haute cuisine is traditionally French, but other countries have similar concepts of food. People often compare Japanese kaiseki to haute cuisine. Kaiseki is another very complicated, very high level kind of food. In Japan, kaiseki is also considered a kind of art. When Japanese chefs prepare kaiseki, they don't just consider the taste of the food. They also consider the food's texture, colour, and appearance. Chefs even match the colour of the food to the colour of the plate and the chopsticks. Of course, although haute cuisine and kaiseki share many similarities, the food itself is quite different.

     If you ever get the chance to try kaiseki or haute cuisine , remember one thing: You are not just having a meal, you are enjoying a very special kind of art.

1. What can we say about the wines that people drink with haute cuisine?

A. Theyall come from France.

B. They are all quite common.

C. They are always red wine.

D. They are usually rare.

2. What is true about the dishes in haute cuisine?

A. Haute cuisine usually has many small dishes.

B. Haute cuisine usually has just a few large dishes.

C. Haute cuisine usually has many large dishes.

D. Haute cuisine usually has just a few small dishes.

3. What does the fifth sentence of the third paragraph mean?

A. Haute cuisine has to taste good, but is has to be good in other ways, too

B. Haute cuisine only has to taste good.

C. Haute cuisine has to look good, but it doesn't have to taste good.

D. Every haute cuisine dish tastes the same.

4. What does the passage NOT say about haute cuisine?

A. It is very expensive.

B. It takes a short time to make.

C. It is very complicated.

D. It is usually served in fancy hotels and high level restaurants.

5. What does the passage say about kaiseki and haute cuisine?

A. The food is the same in both.

B. People never care about them.

C. People often compare them.

D. Haute cuisine is older than kaiseki.

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 from 55 to 64.

Overpopulation, the situation of having large numbers of people with too few resources and too little space, is closely associated with poverty. It can result from high population density, or from low amounts of resources, or from both. Excessively high population densities put stress on available resources. Only a certainnumber of people can be supported on a given area of land, and that number depends on how much food and other resources the land can provide. In countries where people live primarily by means of simple farming, gardening, herding, hunting, and gathering, even large areas of land can support only small numbers of people because these labor-intensive subsistence activities produce only small amounts of food.
In developed countries such as the United States, Japan, and the countries of Western Europe, overpopulation generally is not considered a major cause of poverty. These countries produce large quantities of food through mechanized farming, which depends on commercial fertilizers, large-scale irrigation, and agricultural machinery. This form of production provides enough food to support the high densities of people in metropolitan areas.
A country’s level of poverty can depend greatly on its mix of population density and agricultural productivity. Bangladesh, for example, has one of the world’s highest population densities, with 1,147 persons per sq km. A large majority of the people of Bangladesh engage in low-productivity manual farming, which contributes to the country’s extremely high level of poverty. Some of the smaller countries in Western Europe, such as the Netherlands and Belgium, have high population densities as well. These countries practice mechanized farming and are involved in high-tech industries, however, and therefore have high standards of living.
At the other end of the spectrum, many countries in sub-Saharan Africa have population densities of less than 30 persons per sq km. Many people in these countries practice manual subsistence farming; these countries also have infertile land, and lack the economic resources and technology to boost productivity. As a consequence, these nations are very poor. The United States has both relatively low population density and high agricultural productivity; it is one of the world’s wealthiest nations.
High birth rates contribute to overpopulation in many developing countries. Children are assets to many poor families because they provide labor, usually for farming. Cultural norms in traditionally rural societies commonly sanction the value of large families. Also, the governments of developing countries often provide
little or no support, financial or political, for family planning; even people who wish to keep their families small have difficulty doing so. For all these reasons, developing countries tend to have high rates of population growth.
