2. Essay on "Argumentative Discussion about a Thought or Moral Issue" No. 5
Question 1. Practice Exercise on pages 36 - 37, Textbook.
Read the following passage and answer the questions.
TIME IS GOLD
There is a proverb saying: Time is gold. However, gold can be bought, while time cannot. This shows that gold is valuable, but time is priceless.
Indeed, time is life. Go to a hospital and observe; if a patient is treated on time, they survive; delay can lead to death.
Time is victory. Ask the soldiers; in battle, seizing the right moment to strike ensures victory, losing the opportunity results in defeat.
Time is money. In business, producing goods at the right time results in profit; delay causes loss.
Time is knowledge. One must study regularly to excel. If you study a language inconsistently, with no perseverance, you won't become proficient.
Thus, if you utilize time wisely, you can achieve so much for yourself and society. Wasting time harms you, and regretting it later will be futile.
(Phương Liên)
Questions:
a) What type of essay is the passage above?
b) What issue does the essay discuss? Identify its main argument.
c) What is the primary reasoning method in this essay? How persuasive is the method used?
Answer:
To complete this exercise, first note the meaning of the title “Time is Gold,” which refers to the value of time. This is an argumentative essay on thoughts and morals, addressing why time must be valued. Secondly, each paragraph in the essay highlights a special value of time: it is irreplaceable, irreversible, cannot be delayed, and cannot be bought. Thirdly, the essay proves the value of time through reasoning. The structure follows a logical progression: time is priceless, time is life, time is victory, time is money, and time is knowledge.
Question 2. Thoughts on the Fable “Carving the Wood in the Middle of the Road.”
Answer:
From the fable “Carving the Wood in the Middle of the Road,” many lessons can be drawn. For example, it teaches the lesson of failure. Wasting a good piece of wood without achieving the goal of carving it is a failure. It serves as a lesson for those who lack decisiveness, who follow others without thinking critically. It also teaches the lesson about the “advice” of others—many people give random advice, thinking themselves wise without any solid foundation. From these ideas, one can analyze the right and wrong, the wise and the foolish in the story, and express their opinion on each type of character in the fable.
Question 3. Competing and Yielding.
Answer:
Everyone likely remembers the fable about two goats crossing a narrow wooden bridge from opposite directions. Neither was willing to yield, and they both fell into the river. This could serve as an introduction to a discussion on the topic of competition and yielding. Consider scenarios where competition and yielding often arise. For example: Two people want to buy the same toy, but there is only one left in the store; two people want to buy a book, but only one copy is available; two people try to sit in the last available seat on a bus, etc. From these situations, we can analyze the pros, cons, and suggest solutions.
Question 4. Respect for the Elderly.
Answer:
Respecting the elderly is a noble tradition. Why should people honor the elderly? They are the parents, grandparents, and ancestors who have gained life experience and wisdom. They are those who have worked to raise and educate younger generations. They have contributed to the material and spiritual wealth of society. How should we honor the elderly to show respect? By recognizing their values, listening to their advice, and helping them when needed. Why should we respect them? Because they are often old and frail, and no one should hold disdain for them. Honoring the elderly also means respecting humanity, as we all will age and become frail one day. This is the moral of life.
Question 5. The Healthy Should Help the Needy.
Answer:
“The healthy should help the needy” is a Vietnamese proverb that refers to the spirit of helping others in times of hardship. In a community, we cannot avoid seeing some areas or individuals suffering from disasters. In such conditions, those who are fortunate or have the means (the healthy) should help those affected (the needy) to get through the crisis. “Helping” means offering support and care. This action is practiced by people of the same ethnicity, culture, and territory (all are “leaves” on the same tree). This tradition has been maintained and even strengthened today. Vietnam faces many natural disasters, so this spirit of solidarity remains strong. No one can escape misfortune, and helping others is also helping oneself. Nowadays, charitable activities continue this tradition. Even children contribute to such meaningful acts.

A. KEY CONCEPTS
I- ARGUMENTATIVE ESSAY ON A PHILOSOPHICAL OR ETHICAL ISSUE
KNOWLEDGE IS POWER
The English scientist Francis Bacon (16th - 17th century) famously said, "Knowledge is power." Later, Lenin, a teacher of the world proletarian revolution, elaborated, "He who has knowledge has power." This is a profound idea. However, not everyone understands this concept.
Indeed, knowledge is power. It is said that a large generator of the Pho company broke down, and a committee of engineers spent three months trying to find the cause without success. They called in expert Xten-met-xo, who quickly fixed the machine. The company paid him $10,000. Many thought Xten-met-xo was greedy. But on the receipt, Xten-met-xo wrote: "The cost of drawing a straight line is $1. The cost of finding the right place to draw it is $9,999." Clearly, someone with profound knowledge can do things that others cannot. Without knowing how to fix it, could the machine have avoided becoming a pile of scrap metal?
Knowledge is also the power of revolution. After his trip to France in 1946, Uncle Ho attracted many famous intellectuals to join the resistance movement, such as engineer Tran Dai Nghia, Dr. Nguyen Van Huyen, doctors Ton That Tung, Dang Van Ngu, and mathematician Ta Quang Buu... These intellectuals used their knowledge to build the military, education, and healthcare sectors, greatly contributing to the success of the resistance. During the anti-American war, professors Dam Trung Don and Vu Dinh Cu mobilized knowledge to neutralize enemy slow-burning fuses and clear ports. Today, agricultural scientists like Bui Huy Dap and Vu Tuyen Hoang have developed new rice varieties, helping increase agricultural productivity, making our country not only self-sufficient in food but also one of the leading rice exporters in the world.
Knowledge is so powerful, yet unfortunately, many people fail to appreciate it. They see learning as a means to earn a diploma to secure a job or climb the social ladder. They do not realize that to make our country rich, fair, democratic, and civilized, we need countless talented intellectuals in every field!

Practice
Exercise: Page 36, Textbook of Literature 9, Volume 2
Read the following text and answer the questions.
TIME IS GOLD
An old proverb says: Time is gold. But while gold can be bought, time cannot. This shows that while gold has value, time is priceless.
Indeed, time is life. If you visit a hospital, you'll see that a seriously ill patient can live if treated in time, but delayed treatment could lead to death.
Time is victory. Ask any soldier; in battle, seizing the moment to strike the enemy at the right time brings victory, but missing the right moment leads to defeat.
Time is money. In business, producing goods at the right time means profit, but at the wrong time means loss.
Time is knowledge. To be skilled, one must constantly study. If you study a foreign language intermittently without perseverance, you will never become fluent.
This shows that if we use time wisely, we can achieve much for ourselves and society. Wasting time brings harm, and later regrets are too late to reverse.
