Answer
C
Correct Sentence: ็งใฏๆฏใซๆ–ฐ่ž็ด™ใ‚’ๆจใฆใ‚‰ใ‚Œใพใ—ใŸ。
Explanation: ๆจใฆใ‚‹ is a Group 2 (ichidan) verb, and Group 2 verbs form the passive by removing the final ใ‚‹ and adding ใ‚‰ใ‚Œใ‚‹: ๆจใฆใ‚‹ → ๆจใฆใ‚‰ใ‚Œใ‚‹. In the polite past, this becomes ๆจใฆใ‚‰ใ‚Œใพใ—ใŸ.

2: Which sentence is grammatically incorrect?

Correct Sentence: ใ“ใฎ่‡ชๅ‹•่ปŠใฏใ‚‚ใฃใจๅฎ‰ใ‹ใฃใŸใ‚‰ใ„ใ„ใงใ™ใญ。
Explanation: ๅฎ‰ใ„ is an ใ„-adjective, and when an ใ„-adjective is used with the conditional pattern ~ใŸใ‚‰, it changes to its past form first: ๅฎ‰ใ„ → ๅฎ‰ใ‹ใฃใŸ → ๅฎ‰ใ‹ใฃใŸใ‚‰.

3: Which sentence is grammatically incorrect?

Choices
A: ใ“ใฎ้“ใฏ่‡ชๅ‹•่ปŠใŒๅคšใใฆ、ๅฑ้™บใงใ™。

D: ใ“ใฎใ‹ใฐใ‚“ใฏๅคงใใ™ใŽใพใ™。
Answer
C
Correct Sentence: ๅฟ™ใ—ใใฆใ‚‚、ไปŠๅคœๆœฌ็คพใซ้€ฃ็ตกใ—ใพใ™。
Explanation: ๅฟ™ใ—ใ„ is an ใ„-adjective, and to use an ใ„-adjective with the concessive pattern ~ใฆใ‚‚ (“even if / although”), change the final ใ„ to ใใฆ and add ใ‚‚: ๅฟ™ใ—ใ„ → ๅฟ™ใ—ใใฆ → ๅฟ™ใ—ใใฆใ‚‚.

4: Which sentence is grammatically incorrect?

Explanation: ๆ—ฅๆ›œๆ—ฅ is a noun, and when a noun is used with the concessive pattern meaning “even if / even on,” the correct form is noun + ใงใ‚‚, not noun + ใฆใ‚‚.

5: Which sentence is grammatically incorrect?

Choices
A: ใใ‚ใใ‚ๆœฌ็คพใซ้€ฃ็ตกใ—ใชใใฆใฏใ„ใ‘ใพใ›ใ‚“。

D: ้›จใชใ‚‰、ๅ‚˜ใŒๅฟ…่ฆใงใ™。
Answer
C
Correct Sentence: ๆ˜Žๆ—ฅใฏไผ‘ใฟใ ใจใ„ใ„ใงใ™ใญ。
Explanation: ไผ‘ใฟ is a noun, and when a noun is used with the pattern ~ใจใ„ใ„ to express a hope or wish, it needs the copula ใ  before ใจ: noun + ใ ใจใ„ใ„.

✅ Choice

Choose the best option to complete the sentence.
Goal: Practice selecting the correct grammar form according to the context.

1: ไปŠๆ—ฅใฏๆฐ—ๅˆ†ใŒใ‚ˆใใ‚ใ‚Šใพใ›ใ‚“。ใงใ‚‚、ๅคงๅˆ‡ใช่ฉฆ้จ“ใชใฎใง、ๅ—ใ‘ใชใใฆใฏใ„ใ‘ใพใ›ใ‚“。ๆฐ—ๅˆ†ใŒ(      )、่ฉฆ้จ“ใ‚’ๅ—ใ‘ใพใ™。

C: ใ‚ˆใใชใ„ใจใ„ใ„ใงใ™ใŒ
D: ใ‚ˆใใชใฃใŸใ‚‰
Answer
B
Explanation: ~ใฆใ‚‚ is used to express a contrast or concession, meaning “even if” or “even though.” Here, the speaker is not feeling well but will take the exam anyway, so ใ‚ˆใใชใใฆใ‚‚ correctly shows that the action happens despite the negative condition.

2: ๆ•…้šœใ—ใŸ่‡ชๅ‹•่ปŠใฎไฟฎ็†ใŒ、ๆœฌๆ—ฅๆœฌ็คพใง็ต‚ใ‚ใ‚Šใพใ—ใŸ。ใใฎ่‡ชๅ‹•่ปŠใฏๆœฌ็คพใง(      )。

Choices
A: ไฟฎ็†ใ—ใฆใ‚‚ใ„ใ„ใงใ™
B: ไฟฎ็†ใ—ใฆใฟใŸใ„ใงใ™
C: ไฟฎ็†ใ™ใ‚‹ไบˆๅฎšใงใ™
D: ไฟฎ็†ใ•ใ‚Œใพใ—ใŸ
Answer
D
Explanation: ไฟฎ็†ใ•ใ‚Œใพใ—ใŸ is the passive form of ไฟฎ็†ใ™ใ‚‹ and is appropriate because the car receives the action of being repaired. The previous sentence states that the repair was completed today, so the second sentence must describe a completed past action.

3: ไฟฎ็†ใ—ใฆใ‚‚ใ‚‰ใฃใŸใ‚นใƒžใƒผใƒˆใƒ•ใ‚ฉใƒณใ‚’ใพใŸไฝฟใฃใฆใ„ใพใ™。ไปŠใฏๆ•…้šœใ—ใฆใ„ใพใ›ใ‚“。ใ“ใ‚Œใ‹ใ‚‰ใ‚‚(      )。

D: ๆ•…้šœใ—ใชใ„ใจใ„ใ„ใงใ™ใญ
Answer
D
Explanation: ~ใจใ„ใ„ is commonly used to express a hope or wish about a future situation, so ๆ•…้šœใ—ใชใ„ใจใ„ใ„ใงใ™ใญ naturally means that the speaker hopes the smartphone will continue working without breaking down. The word ใ“ใ‚Œใ‹ใ‚‰ใ‚‚ reinforces this future-oriented meaning.

4: A:่‡ชๅ‹•่ปŠใŒ้€”ไธญใงๆ•…้šœใ—ใŸใ‚“ใงใ™ใŒ、ใฉใ†ใ—ใŸใ‚‰ใ„ใ„ใงใ™ใ‹。 B:ๆœฌ็คพใซ(      )。

A: ้€ฃ็ตกใ—ใŸใ‚‰ใ„ใ„ใงใ™ใ‚ˆ
B: ้€ฃ็ตกใ—ใฆใ‚‰ใ„ใ„ใงใ™ใ‚ˆ
C: ้€ฃ็ตกใ™ใ‚‹ใŸใ‚‰ใ„ใ„ใงใ™ใ‚ˆ
D: ้€ฃ็ตกใ—ใŸใจใ„ใ„ใงใ™ใ‚ˆ
Answer
A
Explanation: ~ใŸใ‚‰ใ„ใ„ is commonly used to give advice or suggest a good course of action, especially in response to questions such as ใฉใ†ใ—ใŸใ‚‰ใ„ใ„ใงใ™ใ‹ (“What should I do?”). To form this pattern with ้€ฃ็ตกใ™ใ‚‹, the verb changes to the past form ้€ฃ็ตกใ—ใŸ and then takes ใ‚‰, giving ้€ฃ็ตกใ—ใŸใ‚‰ใ„ใ„.

✏️ Correct

Find and fix the grammar mistake in the sentence.
Goal: Practice applying grammar rules and producing accurate Japanese sentences.

1: ็”ณ่พผๆ›ธใŒๅˆ†ใ‹ใ‚‰ใชใ‹ใฃใŸใ‚‰、ๆ‹…ๅฝ“ใฎไบบใซ็›ธ่ซ‡ใ—ใฆใจใ„ใ„ใงใ™。

Answer
็”ณ่พผๆ›ธใŒๅˆ†ใ‹ใ‚‰ใชใ‹ใฃใŸใ‚‰、ๆ‹…ๅฝ“ใฎไบบใซ็›ธ่ซ‡ใ™ใ‚‹ใจใ„ใ„ใงใ™。
Explanation: The pattern ~ใจใ„ใ„ใงใ™ is used to give advice or say that doing something would be a good idea, and it normally follows the dictionary form of a verb.

2: ่‡ชๅ‹•่ปŠใฏๆœฌ็คพใงไฟฎ็†ใ•ใ‚Œใชใ„ใงใ—ใŸ。

Answer
่‡ชๅ‹•่ปŠใฏๆœฌ็คพใงไฟฎ็†ใ•ใ‚Œใพใ›ใ‚“ใงใ—ใŸ。
Explanation: For verbs in the polite negative past, use ~ใพใ›ใ‚“ใงใ—ใŸ, not ~ใชใ„ใงใ—ใŸ. The passive verb ไฟฎ็†ใ•ใ‚Œใ‚‹ therefore changes to ไฟฎ็†ใ•ใ‚Œใพใ›ใ‚“ใงใ—ใŸ when saying that something was not repaired.

3: ็งใฏๅผŸใซใ‚นใƒžใƒผใƒˆใƒ•ใ‚ฉใƒณใ‚’ๅฃŠใ—ใ‚‰ใ‚Œใพใ—ใŸ。

Answer
็งใฏๅผŸใซใ‚นใƒžใƒผใƒˆใƒ•ใ‚ฉใƒณใ‚’ๅฃŠใ•ใ‚Œใพใ—ใŸ。
Explanation: For a Group 1 verb such as ๅฃŠใ™, the passive form is made by changing the final -u sound to the corresponding -a sound and adding ใ‚Œใ‚‹. Therefore, ๅฃŠใ™ becomes ๅฃŠใ•ใ‚Œใ‚‹.

2. Practice

Goal: Practice using the grammar in different situations.
Apply the grammar by correcting, transforming, and creating sentences.

Answer
B
Correct Sentence: ๆฐ—ๅˆ†ใŒๆ‚ชใ„ใจใใฏ、ๅฐ‘ใ—ไผ‘ใ‚€ใจใ„ใ„ใงใ™。
Explanation: The pattern ~ใจใ„ใ„ใงใ™ is used to give advice or express that doing something would be a good idea, and it attaches to the plain non-past form of a verb: verb (dictionary form) + ใจใ„ใ„ใงใ™.

2: Which sentence is grammatically incorrect?

Answer
B
Correct Sentence: ้›จใŒ้™ใฃใฆใ‚‚、็ฅž็คพใธ่กŒใใพใ™。
Explanation: ้™ใ‚‹ is a Group 1 (godan) verb, and to use a verb with the concessive pattern ~ใฆใ‚‚ (“even if / even though”), first change the verb to its ใฆ-form and then add ใ‚‚. For ้™ใ‚‹, the ใฆ-form is ้™ใฃใฆ, so the correct pattern is ้™ใฃใฆใ‚‚.

Answer
D
Correct Sentence: ็งใฏๆณฅๆฃ’ใซ่ฒกๅธƒใ‚’็›—ใพใ‚Œใพใ—ใŸ。
Explanation: ็›—ใ‚€ is a Group 1 (godan) verb, and Group 1 verbs form the passive by changing the final u-sound to the corresponding a-sound and adding ใ‚Œใ‚‹: ็›—ใ‚€ → ็›—ใพใ‚Œใ‚‹.

Explanation: The advice pattern ~ใŸใ‚‰ใ„ใ„ใงใ™/~ใŸใ‚‰ใ„ใ„ใงใ™ใ‚ˆ is formed by using the past plain form of the verb + ใ‚‰. ่กŒใ is a Group 1 (godan) verb, and its past plain form is ่กŒใฃใŸ, so the correct form is ่กŒใฃใŸใ‚‰ใ„ใ„ใงใ™ใ‚ˆ.

5: Which sentence is grammatically incorrect?

Answer
B
Correct Sentence: ใ“ใฎ่‡ชๅ‹•่ปŠใฏๆ—ฅๆœฌใงไฝœใ‚‰ใ‚Œใพใ—ใŸ。
Explanation: In a passive sentence, the place where an action is performed is normally marked with ใง, not ใซ. Here, ไฝœใ‚‰ใ‚Œใพใ—ใŸ is the passive form of the Group 1 verb ไฝœใ‚‹, and ๆ—ฅๆœฌ indicates the location where the car was made, so the correct pattern is place + ใง + passive verb: ๆ—ฅๆœฌใงไฝœใ‚‰ใ‚Œใพใ—ใŸ. The particle ใซ is generally used to mark the agent in passive sentences, as in ็คพๅ“กใซ่ชญใพใ‚Œใพใ—ใŸ, rather than the place where the action occurs.

✏️ Correct

Goal: Practice applying grammar rules and producing accurate Japanese sentences.

1: ๆฐ—ๅˆ†ใŒๆ‚ชใ„ใฆใ‚‚、ๅคงๅญฆใซ่กŒใใพใ™。

Answer
ๆฐ—ๅˆ†ใŒๆ‚ชใใฆใ‚‚、ๅคงๅญฆใซ่กŒใใพใ™。
Explanation: With ใ„-adjectives, ~ใฆใ‚‚ is formed by changing the final ใ„ to ใใฆ and then adding ใ‚‚. Therefore, ๆ‚ชใ„ becomes ๆ‚ชใใฆใ‚‚, not ๆ‚ชใ„ใฆใ‚‚. This pattern is used to express a concessive meaning such as “even if” or “even though,”.

2: ๅผŸใŒ่ฉฆ้จ“ใซๅˆๆ ผใงใใ‚‹ใŸใ‚‰ใ„ใ„ใงใ™ใญ。

Answer
ๅผŸใŒ่ฉฆ้จ“ใซๅˆๆ ผใงใใŸใ‚‰ใ„ใ„ใงใ™ใญ。
Explanation: The pattern ~ใŸใ‚‰ is formed from the past plain form of a verb plus ใ‚‰. Therefore, ใงใใ‚‹ first changes to ใงใใŸ, and then ใ‚‰ is added: ใงใใŸใ‚‰.

3: ็งใฏๆฏใซๆ–ฐ่ž็ด™ใ‚’ๆจใฆใ•ใ‚Œใพใ—ใŸ。

Answer
็งใฏๆฏใซๆ–ฐ่ž็ด™ใ‚’ๆจใฆใ‚‰ใ‚Œใพใ—ใŸ。
Explanation: For a Group 2 verb such as ๆจใฆใ‚‹, the passive form is made by removing the final ใ‚‹ and adding ใ‚‰ใ‚Œใ‚‹. Therefore, ๆจใฆใ‚‹ becomes ๆจใฆใ‚‰ใ‚Œใ‚‹, and in the polite past it becomes ๆจใฆใ‚‰ใ‚Œใพใ—ใŸ.

4: ๆ˜Žๆ—ฅใฏๅคฉๆฐ—ใŒใ‚ˆใใจใ„ใ„ใงใ™ใญ。

Answer
ๆ˜Žๆ—ฅใฏๅคฉๆฐ—ใŒใ„ใ„ใจใ„ใ„ใงใ™ใญ。
Explanation: Before ~ใจใ„ใ„ใงใ™ใญ, an ใ„-adjective normally stays in its plain form, so ใ„ใ„ is used directly: ใ„ใ„ใจใ„ใ„ใงใ™ใญ. The form ใ‚ˆใ is the adverbial form of ใ„ใ„ and is used when modifying a verb or in certain other constructions, but it cannot be used here before ใจใ„ใ„.

5: ็งใฏๆณฅๆฃ’ใ‚’่ฒกๅธƒใ‚’็›—ใพใ‚Œใพใ—ใŸ。

Answer
็งใฏๆณฅๆฃ’ใซ่ฒกๅธƒใ‚’็›—ใพใ‚Œใพใ—ใŸ。
Explanation: In a passive sentence, the person who performs the action is usually marked with ใซ, while the thing directly affected by the action can still be marked with ใ‚’ in an adversative passive construction.

✏️ Rewrite

Rewrite the sentence using the given grammar pattern.
Goal: Practice expressing the same idea using different grammar structures.

1: ๆณฅๆฃ’ใŒ็งใฎ่ฒกๅธƒใ‚’็›—ใฟใพใ—ใŸ。

Rewrite the sentence using: Passive form
Answer
็งใฏๆณฅๆฃ’ใซ่ฒกๅธƒใ‚’็›—ใพใ‚Œใพใ—ใŸ。
Explanation: The passive form shifts the focus from the person who performed the action to the person affected by it. Here, ใซ marks the person responsible for the action, while ็›—ใพใ‚Œใพใ—ใŸ shows that the speaker experienced the theft as something unwanted or harmful. This is a common use of the Japanese passive, especially when describing inconvenience, loss, or a negative experience.

2: ็”ณ่พผๆ›ธใŒๅˆ†ใ‹ใ‚‰ใชใ„ใจใ、่ชฐใซ่žใ‘ใฐใ„ใ„ใงใ™ใ‹。

Rewrite the sentence using: ~ใŸใ‚‰ใ„ใ„ใงใ™ใ‹
Answer
็”ณ่พผๆ›ธใŒๅˆ†ใ‹ใ‚‰ใชใ„ใจใ、่ชฐใซ่žใ„ใŸใ‚‰ใ„ใ„ใงใ™ใ‹。
Explanation: ~ใŸใ‚‰ใ„ใ„ใงใ™ใ‹ is commonly used to ask for advice about what action would be best in a particular situation. Compared with ~ใฐใ„ใ„ใงใ™ใ‹, it sounds slightly more conversational and natural in everyday speech, while keeping the same basic meaning of asking “what should I do?”. Here, the past-form verb before ใ‚‰ does not indicate past time; it is part of the conditional pattern ~ใŸใ‚‰ใ„ใ„ใงใ™ใ‹.

3: ๆ˜Žๆ—ฅ、ๅคฉๆฐ—ใŒใ‚ˆใใชใ‚Œใฐๅฌ‰ใ—ใ„ใงใ™。

Rewrite the sentence using: ~ใจใ„ใ„ใงใ™
Answer
ๆ˜Žๆ—ฅ、ๅคฉๆฐ—ใŒใ‚ˆใใชใ‚‹ใจใ„ใ„ใงใ™。
Explanation: ~ใจใ„ใ„ใงใ™ is used to express a hope or wish that a certain situation will happen. Compared with ~ใฐๅฌ‰ใ—ใ„ใงใ™, it sounds more like a general hope about the outcome, rather than directly emphasizing the speaker’s feeling of happiness. Before ใจใ„ใ„ใงใ™, the verb is normally used in its plain non-past form, so ใ‚ˆใใชใ‚‹ is the natural choice here.

Rewrite the sentence using: ~ใŸใ‚‰ใ„ใ„ใงใ™ใ‹
Answer
ใ‚นใƒžใƒผใƒˆใƒ•ใ‚ฉใƒณใŒๆ•…้šœใ—ใŸใจใ、ใฉใ“ใซ็›ธ่ซ‡ใ—ใŸใ‚‰ใ„ใ„ใงใ™ใ‹。
Explanation: This sentence is valid and natural. ~ใŸใ‚‰ใ„ใ„ใงใ™ใ‹ is commonly used to ask for advice about what action would be appropriate in a certain situation. Compared with ~ใฐใ„ใ„ใงใ™ใ‹, it has essentially the same meaning but often sounds a little more conversational in everyday Japanese. The form ็›ธ่ซ‡ใ—ใŸใ‚‰ does not refer to a past action here; it is the conditional form used in the pattern ~ใŸใ‚‰ใ„ใ„ใงใ™ใ‹.

5: ๆ•…้šœใ—ใŸ็‚Š้ฃฏๅ™จใ‚’ๆœฌ็คพใงไฟฎ็†ใ—ใพใ—ใŸ。

Rewrite the sentence using: Passive form
Answer
ๆ•…้šœใ—ใŸ็‚Š้ฃฏๅ™จใฏๆœฌ็คพใงไฟฎ็†ใ•ใ‚Œใพใ—ใŸ。
Explanation: This sentence is valid and natural. The passive form shifts the focus from the company or staff doing the repair to the rice cooker that received the action. ๆœฌ็คพใง indicates the place where the repair took place, while ไฟฎ็†ใ•ใ‚Œใพใ—ใŸ presents the repair as something done to the appliance. Compared with the active sentence, the passive version sounds more objective and is especially common when describing procedures, services, or completed work.

Answer

Correct Sentence: ไบค้€šใŒไธไพฟใงใ‚‚、ใ“ใ“ใซไฝใฟใŸใ„ใงใ™。
Explanation: ไธไพฟ is a ใช-adjective, and when a ใช-adjective is used with the concessive pattern ~ใฆใ‚‚ (“even if / although”), the correct form is ใช-adjective + ใงใ‚‚.

D: ๆ—…่กŒใฎๅ‰ใซ、่ท็‰ฉใ‚’ๆบ–ๅ‚™ใ—ใฆใŠใใพใ™。
Answer
C
Correct Sentence: ๅœฐๅ›ณใŒใชใใฆใ‚‚、้ง…ใพใง่กŒใ‘ใพใ™。
Explanation: ใชใ„ behaves like an ใ„-adjective, and to use it with the concessive pattern ~ใฆใ‚‚ (“even if / even without”), change ใชใ„ to ใชใใฆ and add ใ‚‚: ใชใ„ → ใชใใฆ → ใชใใฆใ‚‚.

Correct Sentence: ไฟฎ็†ใŒๅฟ…่ฆใชใ‚‰、ๅบ—ใฎไบบใซ็›ธ่ซ‡ใ—ใŸใ‚‰ใ„ใ„ใงใ™。
Explanation: The advice pattern ~ใŸใ‚‰ใ„ใ„ใงใ™ is formed with the past plain form of a verb + ใ‚‰ + ใ„ใ„ใงใ™. ็›ธ่ซ‡ใ™ใ‚‹ is an irregular ใ™ใ‚‹-verb, and its past plain form is ็›ธ่ซ‡ใ—ใŸ, so the correct form is ็›ธ่ซ‡ใ—ใŸใ‚‰ใ„ใ„ใงใ™.

Explanation: For verbs, the concessive pattern ~ใฆใ‚‚ is formed from the ใฆ-form plus ใ‚‚, not from the past form. Since ๆ•…้šœใ™ใ‚‹ is a ใ™ใ‚‹ verb, its ใฆ-form is ๆ•…้šœใ—ใฆ, so the correct form is ๆ•…้šœใ—ใฆใ‚‚.

2: ใใ‚ใใ‚ๆœฌ็คพใซ้€ฃ็ตกใ—ใฆใ‚‰ใ„ใ„ใงใ™ใ‚ˆ。

Answer
ใใ‚ใใ‚ๆœฌ็คพใซ้€ฃ็ตกใ—ใŸใ‚‰ใ„ใ„ใงใ™ใ‚ˆ。
Explanation: The pattern ~ใŸใ‚‰ใ„ใ„ is formed by taking the verb’s plain past form and adding ใ‚‰ใ„ใ„. Since ้€ฃ็ตกใ™ใ‚‹ becomes ้€ฃ็ตกใ—ใŸ in the plain past, the correct form is ้€ฃ็ตกใ—ใŸใ‚‰ใ„ใ„.

Answer
ๆ˜Žๆ—ฅใฏ้›จใŒ้™ใฃใฆใ‚‚、็ฅญใ‚Šใซ่กŒใใพใ™。
Explanation: This sentence is valid and natural. ~ใฆใ‚‚ expresses that the result or decision will remain the same even if a certain condition happens. Compared with ~ใ‹ใ‚‚ใ—ใ‚Œใพใ›ใ‚“ใŒ, which simply presents rain as a possibility before contrasting it with the speaker’s plan, ~ใฆใ‚‚ more clearly emphasizes that the possibility of rain will not change the decision to go to the festival.

2: ใ“ใฎใ‚นใƒžใƒผใƒˆใƒ•ใ‚ฉใƒณใฏ้ซ˜ใ„ใงใ™ใŒ、ๅฟ…่ฆใชใฎใง่ฒทใ†ใคใ‚‚ใ‚Šใงใ™。

Explanation: This sentence is valid and natural. ~ใฆใ‚‚ shows that the speaker’s decision will not change despite a certain condition. Compared with ~ใงใ™ใŒ, which simply contrasts the high price with the intention to buy it, ้ซ˜ใใฆใ‚‚ emphasizes that even if the smartphone is expensive, that fact does not prevent the speaker from buying it because it is necessary.

3: ๆ˜Žๆ—ฅใฏไผ‘ใฟใ‹ใ‚‚ใ—ใ‚Œใพใ›ใ‚“ใŒ、ๆœฌ็คพใซ้€ฃ็ตกใ™ใ‚‹ใคใ‚‚ใ‚Šใงใ™。

Explanation: This sentence is valid and natural. With nouns and ใช-adjectives, ~ใฆใ‚‚ takes the form ~ใงใ‚‚. Compared with ~ใ‹ใ‚‚ใ—ใ‚Œใพใ›ใ‚“ใŒ, which presents the day off as a possibility and then adds a contrasting action, ~ใงใ‚‚ emphasizes that even if it is a day off, that condition will not change the speaker’s intention to contact the head office.

The Suggested Answer: ่ฉฆ้จ“ใซๅˆๆ ผใงใใ‚‹ใจใ„ใ„ใงใ™ใญ uses ~ใจใ„ใ„ to express a wish about an outcome that cannot be guaranteed or directly controlled.
