1. Essay on "Parentheses and Colons" No. 4

2. Lesson on "Single Quotation Marks and Colon" No. 5
I. SINGLE QUOTATION MARKS
1. Read the following excerpts and answer the question:
What is the purpose of the single quotation marks in these excerpts?
The single quotation marks in the excerpts are used for the following purposes:
a) To highlight an explanatory note that clarifies the meaning of a term (native people). This additional information, while serving as a note, may also emphasize certain points.
b) To mark a part that provides an explanation about an animal (a type of crab), which is used to refer to a canal, thus helping the reader understand more about the canal’s features.
c) To highlight supplementary information regarding the birth and death years of the poet Li Bai (701-762) and to inform readers about the province (Sichuan) where Mianzhou is located.
2. If the content inside the single quotation marks is removed, does the core meaning of the excerpts change?
The content within the single quotation marks is merely an explanatory note, not essential to the core meaning. Therefore, removing it does not change the basic meaning of the excerpts.
• Remember: Single quotation marks are used to indicate explanatory parts.
II. COLONS
The colon in these excerpts serves to indicate:
a) Introducing dialogue (such as the conversation between the crickets).
b) Introducing a direct quotation (Thép Mới quoting an old saying).
c) Explaining the reason for the author's change in mood on the first day of school.
• Remember: The colon (:) is used to:
- Introduce (precede) additional explanations that clarify or elaborate on a preceding part.
- Introduce (precede) direct quotations (using quotation marks) or dialogue (using a dash).
III. PRACTICE
1. Explain the purpose of single quotation marks:
a) To indicate an explanation for phrases like "tiệt nhiên," "định phận tại thiên thư," "hành khan thủ bại thư."
b) To clarify that the total length of the bridge (2290m) includes the approach sections.
c) The single quotation marks are used in two instances. In the first case, they indicate a supplementary part related to a choice between the author or speaker. This usage often appears in test questions like:
"Please explain the meaning of the proverb 'Gần mực thì đen, gần đèn thì rạng'."
In the first case, single quotation marks highlight explanatory information about language tools.
2. Explain the use of colons:
a) To introduce an explanation for the phrase: 'they challenged too much.'
b) To introduce dialogue (from Dế Choắt to Dế Mèn) and an explanation of Dế Choắt's advice to Dế Mèn.
c) To introduce an explanation for the question: 'What colors are included in the phrase "sufficiently colorful"?'
3. Correct. However, the meaning of the part after the colon is not as emphasized.
4. - Correct. When replaced, the core meaning remains unchanged, but the part inside the single quotation marks adds extra detail, not forming part of the main sentence meaning as it would if it were after the colon.
- If rewritten as "Phong Nha includes: Dry Cave and Water Cave," the colon cannot be replaced by single quotation marks, because the phrase "Dry Cave and Water Cave" cannot be treated as an explanatory note.
Note: Colons can only be replaced by single quotation marks when the omitted part still maintains logical integrity.
5. Incorrect, as single quotation marks (like double quotation marks) must always come in pairs. The teacher instructed students to correct this by adding an additional single quotation mark.
The content marked by single quotation marks is not part of the sentence. This exercise highlights that explanatory notes can be standalone sentences or part of a sentence.

3. Lesson on "Parentheses and Colons" No. 6
I. Basic Knowledge
1. Parentheses
- There are various types of parentheses: round ( ), square [ ], and curly { }. The most commonly used is the round parentheses, while the others are less frequent.
- Function: Parentheses are used to indicate additional explanations, clarifications, or supplementary information.
Examples:
+ Huy (my classmate) came over to invite me to play.
+ The drum sound of Phia (the village chief) echoed through the air.
(Tô Hoài)
+ … His round eyes (so adorable!)
(Giang Nam)
Parentheses serve as punctuation marks that separate a particular part of the sentence, similar to commas or dashes. They help divide a sentence into two different levels: the objective part outside the parentheses and the subjective explanation inside.
Example: In Mường Giơn, he was not the one who studied at the Lò but was solely known as the village chief (headman).
(Tô Hoài)
2. Colons
a. Colons are used to introduce direct speech or dialogues.
+ When introducing direct speech, use it with quotation marks.
Example: President Ho Chi Minh said: "I have one ultimate desire, to make our country fully independent, our people fully free, and every citizen to have food, clothing, and education."
+ When introducing a dialogue, we often use a colon with a dash.
Example: I looked up at him and replied:
- I'm fine.
(L. Pantêlêep)
Seeing that the old man insisted, I finally accepted. Before he left, I asked:
- What will you eat if you give me all the money you've collected?
(Nam Cao)
b. Colons are also used to indicate a supplementary, explanatory, or clarifying part that follows the first part of the sentence.
Explanation: Besides, the children also learn various sports: martial arts, swimming, badminton, table tennis, chess...
Supplement: Actually, the old man secretly thought that, but he still managed to ask me for a bit of dog food.
(Nam Cao)
Explanation: + The grapefruit flowers smell nice, and the night is late.
(Xuân Diệu)
+ The surroundings changed, for my heart was also changing: today, I went to school.
(Thanh Tịnh)
II. Practice Skills

a. The messengers came down after each other (1)
- Please, Sister Hai, go first: (2)
- Sister Lét, go ahead, take care! (3) Some called her Sister Hai, others Sister Lét, no one knew which number she was (4)
(Nguyễn Quang Sáng)
b. The writer Nguyễn Sáng, also known as Nguyễn Sáng, was born in 1932, in An Giang province.
c. The author Nguyễn Huy Tưởng (1912 - 1960), born in Dục Từ village, now in Đông Anh district, Hanoi, was a writer and playwright who started writing before 1945.
d. He is the author of major works: The Long Trì Festival, Princess Ân Tư, Living with the Capital, and many children's stories.
e. I heard my grandmother bragging about it since last summer (1)
- Cửa Tùng, it is the best in our country, sir (2). I have been swimming in all the beaches of our country (3). From the North to the South, from Trà Cổ, Đồ Sơn, Sầm Sơn, Cửa Lò, Đèo Ngang, to Cửa Nhật Lệ, Cửa Thuận, I have bathed in all these places...
(Nguyễn Tuân)
Suggestion:
- Read each sentence carefully and check if the use of colons and parentheses is correct. If incorrect, correct them and explain the mistake.
Example:
a. Sentence 1: Missing a colon at the end of the sentence to introduce dialogue.
b. Sentence 2: The colon used at the end should be replaced with a period.
5. Add parentheses to indicate explanatory content.
2. Explain the use of colons in the following cases:
a. After Tý Hon greeted his father, they took him away, walking for a long time (1). In the evening, Tý Hon said (2):
- Let me rest on the ground for a bit, I really need it (3).
(The Little Tý Hon)
b. You should understand that: helping the people means participating in the resistance war.
(Hồ Chí Minh)
c. They had a very interesting feast: from sausage, meat, eggs, fish, pickled vegetables, to sticky rice, plain rice, sticky cakes...
(Đào Vũ)
d. During the American War, our tasks differed: he continued his role as a cadre holding the gun, while I switched to writing novels and articles.
Suggestion:
Example: a. Sentence 2 - The colon used at the end introduces a dialogue.
b. The colon introduces indirect speech.
3. Write a paragraph of 7 - 10 sentences on a self-chosen topic, using both colons and parentheses.
Suggestion:
- Ensure the paragraph has the correct number of sentences and follows proper grammar.

I. Parentheses
The function of parentheses:
a. (native people) – explanation
b. (three locks, a type of crab trap with sharp purple-red claws, used to make a delicious shrimp paste with garlic and chili) – clarification

a. Colons introduce direct speech or dialogues
b. Colons are used to quote direct speech
c. Colons here are used to explain or clarify the preceding part of the sentence.
EXERCISES

+ This is because a colon is needed after the word "consists of" to list the items.
Exercise 5 (Page 116, 8th Grade Literature)
- The student copied the parentheses incorrectly because they forgot the closing parentheses.
- The part above the parentheses is an additional element in the sentence.
Exercise 6 (Page 116, 8th Grade Literature)
The article "The Population Problem" (by Thái An, Education & Time Newspaper, Sunday edition) discusses the urgent issue of limiting population growth if humanity wants to "survive". Starting with an ancient story about exponential growth, the author leads readers to reflect on the concerning population increase worldwide.

Observe the following sentence and answer the question.
Phong Nha consists of two parts: the dry cave and the water cave.
(Trần Hoàng, Phong Nha Cave)
- Can the colon be replaced by parentheses? If so, would the meaning of the sentence change?
- If rewritten as 'Phong Nha includes: dry cave and water cave,' could the colon be replaced by parentheses? Why?
Detailed Answer:
- Yes. If rewritten this way, the core meaning remains unchanged, but the parentheses would only serve as additional notes, not part of the main sentence, unlike when the colon is used.
- If rewritten as 'Phong Nha consists of: dry cave and water cave,' the colon cannot be replaced by parentheses because the parts 'dry cave and water cave' are not explanatory notes.
Note: The colon can only be replaced by parentheses if omitting it does not affect the overall meaning of the sentence.
Answer to Question 5 (Page 137, Literature 8, Volume 1):
A student copied Thanh Tịnh's passage as follows:
After reading the list of names on the large sheet of paper, the teacher looked at us and said:

(The students all listened, but none dared to answer. Fortunately, a voice from a parent responded.)
- Did the student copy the parentheses correctly or incorrectly? Why?
- Is the content inside the parentheses part of the sentence?
Detailed Answer:
- Incorrectly, because parentheses, like quotation marks, must always come in pairs. The teacher asked the student to fix it by adding the closing parenthesis.
- The content inside the parentheses is not part of the sentence. This exercise emphasizes that footnotes can be part of a sentence or may even be separate sentences.
Answer to Question 6 (Page 137, Literature 8, Volume 1):

Through a story of exponential growth, the author encourages readers to think and reflect on the alarming population increase worldwide. Especially, overpopulation in developing countries leads to economic regression and social welfare issues. Therefore, a reasonable solution is needed for: the population problem.
