Day N5 - 9 - Grammar Practice

Complementary Exercises: Daily N5 - Day 9

After reading the lesson text, practice the grammar points introduced in Day N5-9.

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

Grammar practiced:
✓ ăȘ-adj
✓ ăȘ-adj N
✓ N1 は どんăȘ N2 ですか
✓ ~ăŒă§ăăŸă™
✓ ~から、~

1. Understand

Goal: Recognize and understand how the grammar is used.
Focus on identifying correct patterns and noticing common mistakes.

🔍 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: çˆ¶ăŻćŒ»è€…ă˜ă‚ƒă‚ă‚ŠăŸă›ă‚“。
B: ć›łæ›žé€šăŻćșƒă„です。
C: 仕äș‹ăŻé †èȘżăȘです。
D: 仕äș‹ăŻé †èȘżă§ă™。
Answer
C
Correct Sentence: 仕äș‹ăŻé †èȘżă§ă™。
Explanation: 順èȘż is a ăȘ-adjective. Before a noun, it takes ăȘ, as in 順èȘżăȘ仕äș‹, but before です, it is used without ăȘ.

2: Which sentence is grammatically incorrect?

Choices
A: 昚旄、ç¶șéș—ăȘăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă—ăŸ。
B: ă“ăźăƒ›ăƒ†ăƒ«ăŻă©ă‚“ăȘăƒ›ăƒ†ăƒ«ă§ă™ă‹。
C: æŻăŻć…ƒæ°—ă§ă™。
D: ă“ă‚ŒăŻă©ă‚“ăȘぼ食ăč物ですか。
Answer
D
Correct Sentence: ă“ă‚ŒăŻă©ă‚“ăȘ食ăč物ですか。
Explanation: どんăȘ directly modifies a noun and therefore must be followed by 食ăč物 without た.

3: Which sentence is grammatically incorrect?

Choices
A: ă“ă‚ŒăŻć€§ăă„ć»ș物です。
B: ć…ˆæœˆ、ç¶șéș—ăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă—ăŸ。
C: あれはç¶șéș—ăȘăƒ›ăƒ†ăƒ«ă§ă™。
D: ă“ăźăƒ›ăƒ†ăƒ«ă«ăŻă‚šă‚ąă‚łăƒłăŒă‚ă‚ŠăŸă™。
Answer
B
Correct Sentence: ć…ˆæœˆ、ç¶șéș—ăȘăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă—ăŸ。
Explanation: ç¶șéș— is a ăȘ-adjective, so it requires ăȘ when it directly modifies a noun: ç¶șéș—ăȘăƒ›ăƒ†ăƒ«. In contrast, い-adjectives such as ć€§ăă„ can modify a noun directly without ăȘ, as in ć€§ăă„ć»ș物.

4: Which sentence is grammatically incorrect?

Choices
A: ă“ăźăƒ›ăƒ†ăƒ«ă«ăŻă‚šă‚ąă‚łăƒłăŒă‚ă‚ŠăŸă™。
B: ă“ăźăƒ›ăƒ†ăƒ«ăŻćșƒă„ですから、ćź¶æ—ă§æłŠăŸă‚ŠăŸă™。
C: ä»Šæ™©ăŻä»•äș‹ăŒă‚ă‚ŠăŸă™。
D: ă“ăźăƒ›ăƒ†ăƒ«ăŻç¶șéș—から、ă“ă“ă«æłŠăŸă‚ŠăŸă—ă‚‡ă†。
Answer
D
Correct Sentence: ă“ăźăƒ›ăƒ†ăƒ«ăŻç¶șéș—ですから、ă“ă“ă«æłŠăŸă‚ŠăŸă—ă‚‡ă†。
Explanation: When から expresses a reason after a ăȘ-adjective such as ç¶șéș—, it must follow a copula: ですから in polite speech or だから in plain speech. Therefore, ç¶șéș—から is incomplete; the natural forms are ç¶șéș—ですから or ç¶șéș—だから.

✅ Choice

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

1: A:ć…ˆæœˆ、どんăȘăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă—ăŸă‹。 B:(      )ăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă—ăŸ。

Choices
A: ç¶șéș—
B: ç¶șéș—ăȘ
C: ç¶șéș—た
D: どんăȘ
Answer
B
Explanation: ç¶șéș— is a ăȘ-adjective, so it must be followed by ăȘ when it directly modifies a noun: ç¶șéș—ăȘăƒ›ăƒ†ăƒ«.

2: æ˜šæ—„ăŻæš‘ă‹ăŁăŸ(      )、ć…Źćœ’ăžèĄŒăăŸă›ă‚“ă§ă—ăŸ。

Choices
A: だから
B: から
C: くから
D: ăȘから
Answer
B
Explanation: から expresses a reason and can directly follow the past form of an い-adjective, so æš‘ă‹ăŁăŸă‹ă‚‰ is the correct structure. だから cannot directly follow æš‘ă‹ăŁăŸ, while くから and ăȘから are not valid conjugations for the adjective æš‘ă„.

3: あぼ(      )ć…ˆç”ŸăŻæŻŽæ—„ć­Šæ Ąă«æ„ăŸă™。

Choices
A: ć…ƒæ°—ă§
B: ć…ƒæ°—ăź
C: ć…ƒæ°—
D: ć…ƒæ°—ăȘ
Answer
D
Explanation: ć…ƒæ°— is a ăȘ-adjective, so ăȘ is required when it directly modifies a noun: ć…ƒæ°—ăȘ慈生. ć…ƒæ°— cannot be placed directly before 慈生, た does not connect a ăȘ-adjective to a noun, and で is used to connect ć…ƒæ°— to another description rather than directly modify the noun in this structure.

4: ă“ăźăƒ›ăƒ†ăƒ«ăŻç¶șéș—(      )、æ–™ç†ă‚‚çŸŽć‘łă—ă„ă§ă™。

Choices
A: ăȘ
B: くど
C: で
D: た
Answer
C
Explanation: To connect a ăȘ-adjective to another description, replace だ with で, giving ç¶șéș—で. The form くど is used with い-adjectives, ăȘ is used when directly modifying a noun, and た cannot connect ç¶șéș— to the following clause.

✏️ Correct

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

1: ă‚ă‚ŒăŻć…ƒæ°—ă çŒ«ă§ă™。

Answer
ă‚ă‚ŒăŻć…ƒæ°—ăȘçŒ«ă§ă™。
Explanation: ć…ƒæ°— is a ăȘ-adjective, so when it directly modifies a noun such as 猫, it must be followed by ăȘ. だ is used when the adjective functions as the predicate at the end of a plain-form sentence, as in çŒ«ăŻć…ƒæ°—ă , and cannot connect the adjective directly to a noun.

2: ă‚ăźăƒ›ăƒ†ăƒ«ă«ăŻć…ƒæ°—ćș—ć“ĄăŒă„ăŸă™。

Answer
ă‚ăźăƒ›ăƒ†ăƒ«ă«ăŻć…ƒæ°—ăȘćș—ć“ĄăŒă„ăŸă™。
Explanation: ć…ƒæ°— is a ăȘ-adjective, so it requires ăȘ when it directly modifies a noun such as ćș—擥. Without ăȘ, the adjective cannot grammatically connect to the following noun.

3: ăŠć„œăżç„ŒăăŻă©ă†ăȘæ–™ç†ă§ă™ă‹。

Answer
ăŠć„œăżç„ŒăăŻă©ă‚“ăȘæ–™ç†ă§ă™ă‹。
Explanation: どんăȘ is used directly before a noun to ask what kind of person or thing it is, so it can modify 料理. どう is an adverb and cannot be followed by ăȘ to modify a noun; it is normally used with a predicate, as in 摳はどうですか.

2. Practice

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

🔍 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: ćœ°äž‹é‰„ă«äč—ă‚ŠăŸă™。
B: ä»Šæ™©ăŻä»•äș‹ă‚’するですから、æ˜ ç”»é€šăžèĄŒăăŸă›ă‚“。
C: ä»Šæ™©ăŻæ˜ ç”»é€šăžèĄŒăăŸă›ă‚“。
D: çˆ¶ăŒæ„ăŸă™ă‹ă‚‰、ć…„ă‚ŠćŁă§ćŸ…ăĄăŸă™。
Answer
B
Correct Sentence: ä»Šæ™©ăŻä»•äș‹ă‚’ă—ăŸă™ă‹ă‚‰、æ˜ ç”»é€šăžèĄŒăăŸă›ă‚“。
Explanation: The dictionary form する cannot be followed directly by です. Before から, use either the polite verb form ă—ăŸă™ă‹ă‚‰ or the plain form するから.

2: Which sentence is grammatically incorrect?

Choices
A: æ˜Žæ—„ăŻæ—„æ›œæ—„ă§ă™。
B: çˆ¶ăŻć…ƒæ°—ăȘäŒšç€Ÿć“Ąă§ă™。
C: ă“ăźăƒ›ăƒ†ăƒ«ăŻèż‘ă„ăȘから、æ­©ă„ăŠèĄŒăăŸă™。
D: ć‘łć™Œæ±ăŻç†±ă„ă§ă™ă‹ă‚‰、ăĄă‚‡ăŁăšćŸ…ăĄăŸă—ă‚‡ă†。
Answer
C
Correct Sentence: ă“ăźăƒ›ăƒ†ăƒ«ăŻèż‘ă„ă§ă™ă‹ă‚‰、æ­©ă„ăŠèĄŒăăŸă™。
Explanation: èż‘ă„ is an い-adjective, so ăȘ cannot be placed after it. To give a reason with から, use either the polite pattern èż‘ă„ă§ă™ă‹ă‚‰ or the plain pattern èż‘ă„ă‹ă‚‰. The form ăȘ is used with ăȘ-adjectives before certain expressions, not with い-adjectives such as èż‘ă„.

3: Which sentence is grammatically incorrect?

Choices
A: 揋達はç¶șéș—ăȘăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă—ăŸ。
B: ć…ˆæœˆ、どんăȘăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă—ăŸă§ă™ă‹。
C: あぼć»șç‰©ăŻć€§ăă‹ăŁăŸă§ă™。
D: 昚旄、どんăȘæ–™ç†ă‚’éŁŸăčăŸă—ăŸă‹。
Answer
B
Correct Sentence: ć…ˆæœˆ、どんăȘăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă—ăŸă‹。
Explanation: æłŠăŸă‚ŠăŸă—ăŸ is already the polite past form of æłŠăŸă‚‹, so です cannot be added after it. To form a polite question, simply add the question particle か, producing æłŠăŸă‚ŠăŸă—ăŸă‹.

4: Which sentence is grammatically incorrect?

Choices
A: あれはç¶șéș—ă ăƒ›ăƒ†ăƒ«ă§ă™。
B: これはç¶șéș—ăȘć»ș物です。
C: ă“ăźăƒ›ăƒ†ăƒ«ăŻć€§ăăăŠ、ç¶șéș—です。
D: ć…ƒæ°—ăȘć‹é”ăšć…Źćœ’ăžèĄŒăăŸă™。
Answer
A
Correct Sentence: あれはç¶șéș—ăȘăƒ›ăƒ†ăƒ«ă§ă™。
Explanation: When a ăȘ-adjective directly modifies a noun, it must be followed by ăȘ, as in ç¶șéș—ăȘăƒ›ăƒ†ăƒ«.

5: Which sentence is grammatically incorrect?

Choices
A: ä»ŠæœăŻćŻ’ă„ă§ă™。
B: ă‚šă‚ąă‚łăƒłăŒă‚ă‚ŠăŸă™。

D: æ˜šæ—„ăŻæš‘ă„ă§ă—ăŸă‹ă‚‰、ć›łæ›žé€šă«ć…„ă‚ŠăŸă—ăŸ。
Answer
D
Correct Sentence: æ˜šæ—„ăŻæš‘ă‹ăŁăŸă§ă™ă‹ă‚‰、ć›łæ›žé€šă«ć…„ă‚ŠăŸă—ăŸ。
Explanation: To make an い-adjective past, replace the final い with かった, so æš‘ă„ becomes æš‘ă‹ăŁăŸ.

✏️ Correct

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

1: ä»Šæ™©ăŻä»•äș‹ă‚’ă—ăŸă™ă ă‹ă‚‰、ćˆćŸŒăŻäŒ‘ăżăŸă™。

Answer
ä»Šæ™©ăŻä»•äș‹ă‚’ă—ăŸă™ă‹ă‚‰、ćˆćŸŒăŻäŒ‘ăżăŸă™。
Explanation: To express a reason after a verb in the polite form, attach から directly to ă—ăŸă™.

2: æ˜Žæ—„ăŻæ—„æ›œæ—„ă§ă™ă ă‹ă‚‰、éŠ€èĄŒăŻäŒ‘ăżă§ă™。

Answer
æ˜Žæ—„ăŻæ—„æ›œæ—„ă§ă™ă‹ă‚‰、éŠ€èĄŒăŻäŒ‘ăżă§ă™。
Explanation: To give a reason after the polite copula です, attach から directly to form ですから.

3: ă“ăźăƒ›ăƒ†ăƒ«ăŻă©ă‚“ăȘăźăƒ›ăƒ†ăƒ«ă§ă™ă‹。

Answer
ă“ăźăƒ›ăƒ†ăƒ«ăŻă©ă‚“ăȘăƒ›ăƒ†ăƒ«ă§ă™ă‹。
Explanation: どんăȘ directly modifies a noun and means “what kind of,”.

4: ćŒŸăŻă©ă‚“ăȘăȘ歩生ですか。

Answer
ćŒŸăŻă©ă‚“ăȘ歩生ですか。
Explanation: どんăȘ already functions as a complete modifier meaning “what kind of” and is placed directly before a noun, so an additional ăȘ is not required.

5: これは搌じăȘć»ș物です。

Answer
これは搌じć»ș物です。
Explanation: 搌じ is placed directly before a noun without ăȘ, as in 搌じć»ș物. Although it can describe a noun in a way similar to an adjective, its attributive form is irregular, so it should not follow the usual ăȘ-adjective pattern.

💬 Complete the Dialogue

Fill in the blank to complete the conversation using the proposed grammar pattern.
Goal: Practice applying specific grammar structures to construct natural responses in realistic conversation contexts.

Complete the dialogue using: N1 は どんăȘ N2 ですか

Question 1:
A:杄週、ć…ˆç”ŸăŒæ„ăŸă™。
B:____________。
A:ć…ƒæ°—ăȘ慈生です。

Suggested Answer
ăăźć…ˆç”ŸăŻă©ă‚“ăȘ慈生ですか。
Explanation: Since the teacher has already been mentioned, そぼ慈生 clearly refers back to that person, while どんăȘ慈生ですか asks what kind of teacher they are. This naturally invites a description of the teacher’s characteristics, so the reply ć…ƒæ°—ăȘ慈生です fits the dialogue well and correctly answers the target pattern N1 はどんăȘ N2 ですか.
Complete the dialogue using: ăȘ-adj N

Question 2:
A:æ—„æ›œæ—„ăŻă©ă“ăžèĄŒăăŸă™ă‹。
B:____________。
A:いいですね。ç§ă‚‚äž€ç·’ă«èĄŒăăŸă™。

Suggested Answer
èż‘ăăźç¶șéș—ăȘć…Źćœ’ăžèĄŒăăŸă™。
Explanation: The Suggested Answer naturally states the destination and uses the target pattern ăȘ-adjective + noun in ç¶șéș—ăȘ慬朒, where ăȘ is required to connect ç¶șéș— directly to 慬朒. Adding èż‘ăăź gives more context by identifying it as a nearby park, making the positive reaction and decision to go together fit naturally.
Complete the dialogue using: N1 は どんăȘ N2 ですか

Question 3:
A:あぼć»șç‰©ă«äŒšç€ŸăŒă‚ă‚ŠăŸă™。
B:____________。
A:ć€§ăă„äŒšç€Ÿă§ă™。

Suggested Answer
ăăźäŒšç€ŸăŻă©ă‚“ăȘäŒšç€Ÿă§ă™ă‹。
Explanation: The Suggested Answer uses ăăźäŒšç€Ÿ to refer back to the company just mentioned and どんăȘäŒšç€Ÿă§ă™ă‹ to ask what kind of company it is. This question naturally invites a description, so ć€§ăă„äŒšç€Ÿă§ă™, which describes the company by its size, completes the dialogue appropriately while following the target pattern.
Complete the dialogue using: ăȘ-adj

Question 4:
A:杄週、ă‚ăźăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă™。
B:あぼć»ș物ですか。
A:はい。ç¶șéș—ですか。
B:____________。
A:そうですか。では、èż‘ăăźăƒ›ăƒ†ăƒ«ă«æłŠăŸă‚ŠăŸă™。

Suggested Answer
いいえ、ă‚ăŸă‚Šç¶șéș—ă˜ă‚ƒă‚ă‚ŠăŸă›ă‚“。
Explanation: The Suggested Answer directly responds to the question about the hotel’s appearance and correctly uses the ăȘ-adjective ç¶șéș— in its negative form, ç¶șéș—ă˜ă‚ƒă‚ă‚ŠăŸă›ă‚“. The adverb ă‚ăŸă‚Š is naturally used with a negative expression to mean that the hotel is “not very” attractive, which gives A a clear reason to choose a different nearby hotel.
Complete the dialogue using: ~から、~

Question 5:
A:ă“ăźéƒšć±‹ăŻæš‘ă„ă§ă™ă­。
B:____________。
A:それでは、ă“ă“ă«æłŠăŸă‚ŠăŸă—ă‚‡ă†。

Suggested Answer
ă‚šă‚ąă‚łăƒłăŒă‚ă‚ŠăŸă™ă‹ă‚‰、ć€§äžˆć€«ă§ă™。
Explanation: The Suggested Answer uses から to present the presence of air conditioning as the reason the hot room will not be a problem. ć€§äžˆć€«ă§ă™ reassures A that the situation is manageable, which naturally leads to the decision to stay there.
