I. Training to master the meaning of words and their usage.
Question 1, page 99, 9th Grade Literature Textbook, Volume 1:
The opinion of the late Prime Minister, cultural figure Pham Van Dong, is:
Vietnamese is a rich and beautiful language, capable of meeting all the needs, understanding, and communication of the Vietnamese people.
In order to effectively use the Vietnamese language, individuals must continuously enrich their vocabulary fluently.
Question 2, page 100, 9th Grade Literature Textbook, Volume 1:
a) Error of "redundant words": "landscape" is "beautiful scenery," so it should not be paired with "beautiful" again.
b) Incorrect usage of the word "predict": Prediction is about forecasting future situations. In this case, the correct word should be "guess" or "speculate."
c) Incorrect word combination: "Promote" (to encourage rapid development) cannot be used with "scale" (which refers to size). The word "expand" should replace "promote".
II. Training to expand vocabulary.
The opinion of the writer To Hoai:
The talented pen of Nguyen Du was not innate but learned from the speech of the people.
Enriching vocabulary, besides understanding the exact meaning for correct usage, also involves expanding one's vocabulary by learning new words.

6. Lesson Plan "Building Vocabulary" Number 3
I. Training to fully grasp the meaning and usage of words:
Question 1: Read carefully the opinion of late Prime Minister Pham Van Dong. We can understand that:
- Vietnamese is an incredibly rich and beautiful language, capable of meeting all communication needs of the Vietnamese people.
- To fully harness the potential of the Vietnamese language, each individual must constantly improve their language skills, starting with expanding their vocabulary.
Question 2:
a. Word repetition error: ‘scenic spot’ already means “beautiful scenery,” so it shouldn't be combined with “beautiful” again.
b. Incorrect use of the word “forecast.” “Forecast” refers to predicting future situations or events. In this case, the word “predict” or “guess” should be used instead.
c. Incorrect word combination: “accelerate” (to promote quick development) cannot go with “scale” (indicating size). “Expand” should replace “accelerate” in this context.
These mistakes arise because the writer did not fully understand the meanings and usages of the words they used. Clearly, the issue is not due to a “poor language,” but because the writer didn’t know how to use the language properly. Thus, to “know how to use our language,” one must first master the full and accurate meanings of words and how to use them.
II. Training to increase vocabulary.
Carefully read the passage by To Hoai. We can observe that:
- The brilliant writing style of Nguyen Du was not innate, but rather the result of learning from the language of the people.
- Expanding vocabulary requires not only an accurate understanding of word meanings for correct usage, but also enriching one’s vocabulary by learning new words.
Exercise:
Question 1: Choose the correct explanation:
- Consequence: negative result. Note: “hậu” means “after,” but “hậu quả” (consequence) doesn’t mean “final result” because the Vietnamese language already has the word “kết quả” (result), which carries a positive connotation, while “hậu quả” carries a negative connotation.
- Win: to achieve victory.
- Star: refers to stars in the sky (general term). Note: “tinh” means “star” and “tú” means “beautiful,” but “tinh tú” does not mean “beautiful stars.” The meaning of “pure and precious” is already captured by the term “tinh túy” (essence).
Question 2: Identify the meaning of the following Sino-Vietnamese elements:
a. Tuyệt:
- To end, to have nothing left: tuyệt chủng (extinction), tuyệt giao (cut off communication), tuyệt tự (no descendants), tuyệt thực (hunger strike – a form of protest).
- Extreme, the best: tuyệt đỉnh (highest point), tuyệt mật (top secret), tuyệt tác (masterpiece), tuyệt trần (best in the world, incomparable).
b. Đồng:
- Together, similar: đồng âm (same pronunciation), đồng bào (people of the same ethnicity, nationality, or country – with a connotation of close kinship), đồng bộ (coordinated), đồng chí (comrade), đồng dạng (similar form), đồng khởi (joint uprising to break free from oppression), đồng môn (same school or sect), đồng niên (same age), đồng sự (colleague).
- Children: đồng ấu (children aged 6–7), đồng dao (children’s song), đồng thoại (children’s story).
- (Material) bronze: trống đồng (ancient musical instrument in the shape of a drum, made of bronze, with decorative patterns).
Question 3: Correct the misused words in the following sentences:
a. “Late in the evening, the streets were very quiet.”: Misuse of “quiet.” This word is used for describing people or human-related scenes. It can be replaced by “calm” or “silent.”
b. “During the renovation period, Vietnam established diplomatic relations with most countries in the world.”: Misuse of “established.” This word means “to create or set up an organization such as a government, party, club, etc.” Diplomatic relations are not an organization. The common Vietnamese expression is “set up diplomatic relations.”
c. “His charitable actions deeply moved us.”: Misuse of “emotion.” This word is usually used as a noun, meaning “a feeling caused by something.” It can also be used as a verb, meaning “to feel emotional.” The correct phrase should be “moved” instead of “emotion.”
Question 4: Comment on the opinion of Che Lan Vien.
The Vietnamese language is a pure and beautiful language. This is demonstrated first and foremost through the language of the farmers. To preserve the purity and beauty of the national language, we must learn the words and expressions of the common people.
Question 5: To increase vocabulary, one should:
- Pay attention to observing and listening to the daily speech of those around us, as well as the media such as radio and television.
- Read books, especially exemplary literary works by famous writers.
- Take note of new words encountered, and if there are difficult words that one cannot explain, consult a dictionary or ask others, especially teachers.
- Practice using new words in appropriate communication situations.
Question 6: Choose the appropriate word for each blank in the sentence:
a. A synonym for “weakness” is “flaw.”
b. “Cứu cánh” means “ultimate goal.”
c. To present opinions or wishes to superiors is “to submit.”
d. Quick but lacking seriousness is “rash.”
e. Panic to the point of exhibiting signs of insanity is “chaotic.”
Question 7: Distinguish the meanings of the following word pairs:
a. “Nhuận bút” is “payment for writing a work”; while “thù lao” is “payment for labor (either as a verb or noun). Therefore, the meaning of “thù lao” is much broader than “nhuận bút.”
b. “Tay trắng” means “having no possessions or wealth,” while “trắng tay” means “losing all wealth or possessions, having nothing left.”
c. “Kiểm điểm” means “review or evaluate something in detail,” while “kiểm kê” means “check the quantity and quality of items.”
d. “Lược khảo” means “study the main points in a general way, without going into detail,” while “lược thuật” means “summarize or present briefly.”
