They discovered that they could live in one place, and ____68____ was not such a desperate daily struggle. There was more, food, more leisure time, more security.

Soon after, they began to develop ways of getting ____69____ with as little fighting, anger and ____70____ as before. Eventually, the rules changed as way of living changed.

With increasing development and use of computer technology, there is a new disease to worry about. Computers, are infecting computers in corporations, homes and university.

These viruses spread exponentially, much like biological contagion, and then disrupt the affected systems. The virus secretly attaches itself to other programs and can then delete or alter files. The damage is generally activated by using the computer’s clock. Then, any program that is executed may be exposed to the virus, including program spread through telephone connections. Because of the increasing incidents of virus infiltration, businesses and agencies are becoming wary of sharing software. Security policies need to be increased as immunity programs are being fully developed.

Passage 3

The economic crisis in 1997 made Thai citizens from every region, both the public and private sectors, aware of the vulnerability

of the country's economic foundation and the problems of heavy reliance on foreign investment, technology, and markets. This led to

serious attention being given to the study and analysis of His Majesty's address on the topic of "Sufficiency Economy".

With the main duty of formulating the National Economic and

Social Development Plans as well as coordinating the country's development at policy level, the National Economic and Social Development Board (NESDB) considered it most appropriate to use the

royal philosophy of "Sufficiency Economy" as a guideline for

determining policy, planning and formulating the implementation plan at all levels. This will create a correct and uniform understanding among all the parties concerned, as well as serve as a guideline to help

Thai people earn a good living and the country in overcoming the economic crisis. As a result, after a review and evaluation of His

Majesty's addresses on Sufficiency Economy as well as other related topics, the NESDB sought His Majesty's consideration and his Royal

permission for further reference.

"Sufficiency Economy"

"Sufficiency Economy" is a philosophy bestowed by His Majesty the King to his subjects through royal remarks on many occasions over

the past three decades. The philosophy provides guidance on appropriate conduct covering numerous aspects of life. After the

economic crisis in 1997, His Majesty reiterated and expanded on the "Sufficiency Economy" in remarks made in December 1997 and 1998. The philosophy points the way for recovery that will lead to a more

resilient and sustainable economy, better able to meet the challenges

arising from globalization and other changes.

Philosophy of the "Sufficiency Economy"

"Sufficiency Economy" is a philosophy that stresses the middle

Page 23: Taro Free Net 51

45

path as the overriding principle for appropriate conduct by the populace

at all levels. This applies to conduct at the level of the individual, families, and communities, as well as to the choice of a balanced development strategy for the nation so as to modernize in line with the

forces of globalization while shielding against inevitable shocks and

excesses that arise. "Sufficiency" means moderation and due

consideration in all modes of conduct, as well as the need for sufficient protection from internal and external shocks. To achieve this, the application of knowledge with prudence is essential. In particular, great

care is needed in the utilization of untested theories and methodologies

for planning and implementation. At the same time, it is essential to strengthen the moral fiber of the nation, so that everyone, particularly

public officials, theorists and businessmen, adheres first and foremost

to the principles of honesty and integrity. In addition, a balanced

approach combining patience, perseverance, diligence, wisdom and prudence is indispensable to cope appropriately with critical

challenges arising from extensive and rapid socioeconomic,

environmental, and cultural changes occurring as a result of globalization.

86. Why did Thai public resort to pay more attention to “Sufficiency Economy” after 1997? 1. That was because His Majesty the King has taken this issue seriously. 2. That was because they encountered an economic ordeal from globalization era. 3. That was because they thought the National Economic and Social Development Plans were not workable. 4. That was because they could still rely on foreign investment, technology, and markets. 87. It seems that a correct and uniform understanding among all the parties concerned in “Sufficiency Economy” is vital since ______.

1. this leads to a guideline to help Thais earn a good living and defeat the economic problems.

2. this can tie all Thai people to stay calm in the present political and

social crisis. 3. this is the best performance of NESDB in the past 10 years. 4. Thai people feel more loyal to the King because of his royal initiation. 88. What style of writing is used to create the

first paragraph? 1. classification 2. cause–effect justification 3. comparison 4. commentation

89. How many years ago was “Sufficiency Economy” addressed by His Majesty the King? 1. about 10 years ago 2. about 20 years ago 3. about 30 years ago 4. about 40 years ago 90. What is the main point of the philosophy? 1. To create richness, wealth, and economic growth 2. To overcome poverty, illiteracy, and political unrest 3. To sharpen the abilities to compete with economic rivals in globalization 4. To recover from crisis and establish sustainable development 91. The way to accomplish the ultimate goal of the philosophy is to ______ . 1. seek methods to shield against inevitable capitalism 2. stress the middle path on the middle class 3. modernize the country through western economic theories

4. apply the knowledge with moral awareness focusing on grassroots 92. We can infer from the passage that “Sufficiency Economy” comprehensively covers ______ . 1. globalization, crisis, and middle path 2. balanced approach, moral, and honesty

3. middle path, prudence, protection against shocks 4. public officials, theorists, and businessmen 93. The word “indispensable” ( line 48 ) can be replaced by ______. 1. vital 2. impossible

3. creative 4. accessible

94. We may identify from the passage that external shocks originate from ______ . 1. economic crisis in 1997 2. environmental problems in 20th century 3. corrupt officials and dishonest businessmen 4. globalization and its adverse effects 95.

The word “vulnerability” (line 3) means ______ . 1. turning point 2. standing point 3. strong point 4. weak point 97. “Sufficiency Economy” seems to be anti- globalization concept when judged by its content. To put it another way, “Sufficiency Economy”can be partly described as ____ . 1. internationalism 2. individualism 3. decentralization 4. localization 98. “Sufficiency Economy” best reflects His Majesty the King’s ingenuity in perfect ______ . 1. estimation 2. versatility

Part 5 Reading comprehension The basic morphology of plants reflects their evolutionary history as terrestrial organisms. The algal ancestors of plants were bathed in a solution of water and minerals, including bicarbonate, the source of carbon dioxide for photosynthesis in aquatic habitats. In contrast, the resources a terrestrial plant needs are divided between the soil and air, and the plant must inhabit these two very different environments at the same time. Soil provides water and minerals, but air is the main source of carbon dioxide, and light does not penetrate far into the soil. The evolutionary solution to this separation of resources was differentiation of the plant body into two main systems: a subterranean root system and aerial shoot system consisting of stems, leaves and flowers. Neither system can live without the other. Lacking chloroplasts and living in the dark, roots would starve without sugar and other organic nutrients imported from the photosynthetic tissues of the shoot system. Conversely, the shoot system depends on water and minerals absorbed from the soil by roots. 1. The ancestors of plants used nutrients from the:

a. soil b. air c. water d. algae

2. A terrestrial plant lives in the:

a. soil b. air c. water d. soil and air

3. The plant's evolutionary solution was: a. assimilation b. photosynthesis c. organic d. differentiation

4. The two main plant systems are:

a. stems and leaves b. roots and shoots c. chloroplasts and roots d. flowers and roots

5. The two plant systems:

a. require each other b. are independent c. lack chloroplasts d. are subterranean

L’influence des femmes dans la conception des nouvelles voitures explique la tendance aux formes douces. Pendant une longue période, la voiture a privilégié la puissance et la virilité, mais aujourd’hui elle change de sexe pour devenir séductrice. Les clients recherchent maintenant le confort, la douceur, le silence et la simplicité. C’est ce qui explique le succès du concept de monospace (comme l’Espace Renault) typiquement féminin. Cette féminisation de la voiture a conduit les constructeurs à privilégier les aspects pratiques,la facilité de conduite, l’espace pour les enfants, le volume du coffre pour les courses et les tablettes de rangement. 79. Le meilleur titre de ce texte serait________. a. les Français au volant b. la voiture pour les femmes c. l’auto change de genre d. l’important, c’est la vitesse 80. Quelle affirmation n’est pas vraie ? a. Il y a davantage de place pour les passagers. b. Il est impossible d’avoir un problème de moteur. c. On peut mettre plus d’affaires dans le coffre. d. Ce modèle de voiture a été inspiré par le caractère feminin.
