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"

25

"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

30


26 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 35

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.

The word “indispensable” ( line 48 ) can be replaced by ______. 1. vital 2. impossible 3. creative 4. accessible

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 c. lack chloroplasts

b. are independent d. are subterranean

Part 6 Cloze test Estrogern Is it for you?

This little pill can keep a woman young, but for some it’s risky.

G.” as he later called her, was 52 years old, but she had the smooth skin and youthful body of woman half her age.


71 Asked about menopause, Mrs. P.G. laughed and replied, Dr. Wilson, I have never yet …….1……. a period. I’m so regular, .…2…… could use me for timing the moon. She later revealed that she was ……3.…. birth-control pills containing estrogen and a second female hormone, progesterone. The patient was a walking, talking confirmation of Wilson’s most deeply held medicine ….4.… that treating menopausal women with female hormones could actually prevent menopause and the “fast and painful aging process” that attend it. Three years later, Wilson’s best selling book, Feminine forever, announced the good news to all women. Since then, estrogen-either alone or combined with other hormones in a treatment known as hormones replacement …5... has indeed become the closest thing in a modern medicine to a woman’s …6…. of youth. “I have a hunch that I’ll remain on HRT for the rest of my life, says Frida, a university instructor in her early 70s who feels that estrogen gives her “more energy” and a more …7….appearance.
