Day N5 - 14 - Grammar Practice

Complementary Exercises: Daily N5 - Day 14

After reading the lesson text, practice the grammar points introduced in Day N5-14.

These exercises focus on recognizing mistakes, choosing correct patterns, and producing your own sentences.
They are divided into three study sessions. Each session focuses on a different way of practicing the grammar learned in the shadowing lesson.

Grammar practiced:
✓ V[ใฆ-form]ใใ ใ•ใ„
✓ V[ใชใ„-form]ใชใ„ใงใใ ใ•ใ„
✓ V[ใชใ„-form]ใชใใฆใ‚‚ใ„ใ„ใงใ™
✓ N ใ ใ‘

1. Practice

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

๐Ÿ” Find the Error

Identify the sentence that contains a grammar mistake or unnatural usage.
Goal: Train your ability to notice incorrect grammar patterns and avoid common mistakes.

1: Which sentence is grammatically incorrect?

Choices
A: ไปŠๆ™ฉใฏๅƒใ‹ใชใใฆใ‚‚ใ„ใ„ใงใ™。
B: ใ“ใ“ใซๅ…ฅใ‚‰ใชใ„ใงใใ ใ•ใ„。
C: ๆ˜Žๆ—ฅใฏใ“ใ“ใซๆฅใพใ›ใ‚“ใฆใ‚‚ใ„ใ„ใงใ™。
D: ่ท็‰ฉใฏใ“ใ‚Œใ ใ‘ใงใ™。
Answer
C
Correct Sentence: ๆ˜Žๆ—ฅใฏใ“ใ“ใซๆฅใชใใฆใ‚‚ใ„ใ„ใงใ™。
Explanation: The pattern ~ใชใใฆใ‚‚ใ„ใ„ใงใ™ means “it is okay not to do something” or “you do not have to do something.” It is formed by taking the verb’s negative ใชใ„-form, changing ใชใ„ to ใชใใฆ, and adding ใ‚‚ใ„ใ„ใงใ™. For ๆฅใ‚‹, the negative form is ๆฅใชใ„, so it becomes ๆฅใชใใฆใ‚‚ใ„ใ„ใงใ™.

2: Which sentence is grammatically incorrect?

Choices
A: ่ท็‰ฉใฏไธ€ใคใ ใ‘ใงใ™。

D: ไปŠๆ—ฅใฏไป•ไบ‹ใ‚’ใ—ใชใ„ใงใใ ใ•ใ„。
Answer
B
Correct Sentence: ๆ˜Žๆ—ฅใฏ็ฉบๆธฏใธๆฅใชใ„ใงใใ ใ•ใ„。
Explanation: To make a polite negative request in Japanese, use the ใชใ„-form + ใงใใ ใ•ใ„ pattern, which means “please do not do something.

3: Which sentence is grammatically incorrect?

Choices
A: ๆ˜จๆ—ฅใฏใƒ‘ใƒณใ‚’ใ ใ‘้ฃŸในใพใ—ใŸ。

D: ใ“ใฎใ‚ฑใƒผใ‚ญใ‚’้ฃŸในใชใ„ใงใใ ใ•ใ„。
Answer
A
Correct Sentence: ๆ˜จๆ—ฅใฏใƒ‘ใƒณใ ใ‘ใ‚’้ฃŸในใพใ—ใŸ。
Explanation: The particle ใ ใ‘ (“only”) normally comes directly after the noun it limits, and the case particle ใ‚’ follows it when that noun is the direct object of a verb.

4: Which sentence is grammatically incorrect?

A: ใ“ใฎใƒ‘ใƒณใฏ้ฃŸในใชใใงใ‚‚ใ„ใ„ใงใ™。

Answer
A
Correct Sentence: ใ“ใฎใƒ‘ใƒณใฏ้ฃŸในใชใใฆใ‚‚ใ„ใ„ใงใ™。
Explanation: The pattern ~ใชใใฆใ‚‚ใ„ใ„ใงใ™ means “it is okay not to do something” or “you do not have to do something.” It is formed with the verb’s negative ใชใ„-form, changing ใชใ„ to ใชใใฆ, followed by ใ‚‚ใ„ใ„ใงใ™.

C: ใ—ใŸใ„ใงใ™
D: ใ—ใฆใใ ใ•ใ„
Answer
A
Explanation: 「~ใชใใฆใ‚‚ใ„ใ„ใงใ™」 is used to say that something is not necessary or that someone does not have to do it. Since the speaker has already finished all the preparations and asks whether more preparation is required tomorrow, this form naturally expresses that no further preparation is necessary.

2: A:็งใฏๆ˜Žๆ—ฅ、็ฉบๆธฏใงๅพ…ใฃใฆใ„ใพใ™。ๅˆๅ‰ไนๆ™‚ใซ็ฉบๆธฏใธ(      )。 B:ใ‚ใ‹ใ‚Šใพใ—ใŸ。ๅˆๅ‰ไนๆ™‚ใซ่กŒใใพใ™。

Choices
A: ๆฅใŸใ„ใงใ™
B: ๆฅใชใใฆใ‚‚ใ„ใ„ใงใ™
C: ๆฅใฆใใ ใ•ใ„
D: ๆฅใชใ„ใงใใ ใ•ใ„
Answer
C
Explanation: 「~ใฆใใ ใ•ใ„」 is used to make a polite request. The speaker says they will be waiting at the airport and then asks the listener to come there at 9 a.m. The listener’s reply, 「ใ‚ใ‹ใ‚Šใพใ—ใŸ。ๅˆๅ‰ไนๆ™‚ใซ่กŒใใพใ™」, directly accepts that request.

3: A:ใ“ใฎใ‚ฑใƒผใ‚ญใ‚’้ฃŸในใฆใ‚‚ใ„ใ„ใงใ™ใ‹。 B:ใฏใ„。็พŽๅ‘ณใ—ใ„ใงใ™ใ‹ใ‚‰、ใฉใ†ใž、(      )。 A:ใ‚ใ‚ŠใŒใจใ†ใ”ใ–ใ„ใพใ™。

Choices
A: ้ฃŸในใชใ„ใงใใ ใ•ใ„
B: ้ฃŸในใชใใฆใ‚‚ใ„ใ„ใงใ™
C: ้ฃŸในใฆใใ ใ•ใ„
D: ้ฃŸในใŸใ„ใงใ™
Answer
C
Explanation: 「~ใฆใใ ใ•ใ„」 is used to make a polite request or invitation, and 「ใฉใ†ใž」 often appears with it when encouraging someone to go ahead and do something. Since the listener has already given permission and says the cake is delicious, this form naturally invites the other person to eat it.

4: A:ใ“ใฎๆ–™็†ใ‚’้ฃŸในใฆใ‚‚ใ„ใ„ใงใ™ใ‹。 B:ใพใ ็†ฑใ„ใงใ™ใ‹ใ‚‰、(      )。 A:ใ‚ใ‹ใ‚Šใพใ—ใŸ。

Choices
A: ้ฃŸในใชใใฆใ‚‚ใ„ใ„ใงใ™
B: ้ฃŸในใฆใใ ใ•ใ„
C: ้ฃŸในใชใ‘ใ‚Œใฐใชใ‚Šใพใ›ใ‚“
D: ้ฃŸในใชใ„ใงใใ ใ•ใ„
Answer
D
Explanation: 「~ใชใ„ใงใใ ใ•ใ„」 is used to politely ask someone not to do something. Because the food is still hot, the speaker is warning the listener not to eat it yet. The other choices express that eating is unnecessary, encourage the listener to eat, or say that eating is required, so they do not match the reason given by 「ใพใ ็†ฑใ„ใงใ™ใ‹ใ‚‰」.

✏️ Correct

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

1: ใ“ใฎใ‚ฑใƒผใ‚ญใฏๅ…จ้ƒจ้ฃŸในใชใ„ใฆใ‚‚ใ„ใ„ใงใ™。

Answer
ใ“ใฎใ‚ฑใƒผใ‚ญใฏๅ…จ้ƒจ้ฃŸในใชใใฆใ‚‚ใ„ใ„ใงใ™。
Explanation: To say that it is okay not to do something, the negative ใชใ„-form changes to ใชใใฆ before ใ‚‚ใ„ใ„, giving the pattern ~ใชใใฆใ‚‚ใ„ใ„.

2: ใ“ใฎใ‚ฑใƒผใ‚ญใ‚’้ฃŸในใ‚‹ใใ ใ•ใ„。

Answer
ใ“ใฎใ‚ฑใƒผใ‚ญใ‚’้ฃŸในใฆใใ ใ•ใ„。
Explanation: When making a polite request with ใใ ใ•ใ„, the verb must be in the ใฆ-form, not the dictionary form. Since the ใฆ-form of ้ฃŸในใ‚‹ is ้ฃŸในใฆ, the correct pattern is ้ฃŸในใฆใใ ใ•ใ„.

3: ๆ˜Žๆ—ฅใฏ็ฉบๆธฏใธๆฅใฃใฆใใ ใ•ใ„。

Answer
ๆ˜Žๆ—ฅใฏ็ฉบๆธฏใธๆฅใฆใใ ใ•ใ„。
Explanation: ๆฅใ‚‹(ใใ‚‹) is an irregular verb, so its ใฆ-form must be memorized. It changes to ๆฅใฆ(ใใฆ), not ๆฅใฃใฆ. When making a polite request with ใใ ใ•ใ„, use the pattern verb in the ใฆ-form + ใใ ใ•ใ„.
