Day N5 - 8 - Grammar Practice
Complementary Exercises: Daily N5 - Day 8
After reading the lesson text, practice the grammar points introduced in Day N5-8.
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:
✓ ã-adj
✓ ã-adj N ã§ã
✓ N 㯠ãŠãã§ãã
✓ N 㯠ã-adj ããĻ~
✓ N 㯠ã-adj ã V
✓ ~ã、~
1. Understand
Goal: Recognize and understand how the grammar is used.
Focus on identifying correct patterns and noticing common mistakes.
đ 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?
ChoicesC
Correct Sentence: æ¨æĨã¯æããŖãã§ã。
Explanation: Japanese ã-adjectives form their past tense by changing the final ã to ããŖã, so æã becomes æããŖã. When speaking politely, ã§ã can be added after this past form: æããŖãã§ã. Unlike nouns and ãĒ-adjectives, an ã-adjective does not normally form the past tense by keeping its dictionary form and adding ã§ãã.
2: Which sentence is grammatically incorrect?
ChoicesB
Correct Sentence: ææĨã¯æĨææĨã§ãã、į§ã¯äģäēãããžã。
Explanation: The particle ã can mark the subject of a clause, but it cannot by itself connect two complete statements with the meaning “but.”
3: Which sentence is grammatically incorrect?
ChoicesD
Correct Sentence: æ¯ã¯åŗåæąãįąãããžãã。
Explanation: When an ã-adjective describes the result of changing something with ãã, it changes from 〜ã to 〜ã, as in įąã → įąããã, meaning “to make something hot.” The 〜ããĻ form is mainly used to connect adjectives or clauses, so it cannot be used directly before ããžãã in this pattern.
4: Which sentence is grammatically incorrect?
ChoicesD
Correct Sentence: åŗæ¸é¤¨ã¯å¤§ãããĻ、éŖå ããããžã。
Explanation: When an ã-adjective is used to connect one description to another, change the final ã to ããĻ, as in 大ãã → 大ãããĻ.
✅ Choice
Choose the best option to complete the sentence.
Goal: Practice selecting the correct grammar form according to the context.
1: æ¨æĨã¯( )。
ChoicesB
Explanation: The adjective æã is an ã-adjective, so its polite past form is made by changing ã to ããŖã and adding ã§ã, giving æããŖãã§ã.
2: åŗåæąã¯( )、ãĄããŖã¨åž ãĄãžãã。
ChoicesD
Explanation: įąã is an ã-adjective, and when an ã-adjective connects to another clause, it changes from 〜ã to 〜ããĻ, so įąã becomes įąããĻ.
3: ãåĨŊãŋįŧãã¯( )、å ¨é¨éŖãšãžãã。
ChoicesD
Explanation: įžåŗãã is an ã-adjective, and to connect it to another clause, the final ã changes to ããĻ, giving įžåŗãããĻ.
4: åŗåæąã¯( )、ãĄããŖã¨åž ãĄãžãã。
ChoicesD
Explanation: įąã is an ã-adjective, and its ãĻ-form is made by changing the final ã to ããĻ, giving įąããĻ. This form connects the adjective to the following clause and can express a reason, so it naturally explains why the speaker waited a little.
✏️ Correct
Find and fix the grammar mistake in the sentence.
Goal: Practice applying grammar rules and producing accurate Japanese sentences.
1: ããã¯įąãã§ãåŗåæąã§ã。
ããã¯įąãåŗåæąã§ã。
Explanation: When an ã-adjective directly modifies a noun, it is placed immediately before the noun in its plain form, without ã§ã.
2: ååã¯å¤§ããæ¸ããžãã。
ååã¯å¤§ããæ¸ããžãã。
Explanation: When an ã-adjective describes how an action is performed, change the final ã to ã to make the adverbial form.
3: æ¨æĨã¯æããĻ、å Ŧåã¸čĄããžããã§ãã。
æ¨æĨã¯æããĻ、å Ŧåã¸čĄããžããã§ãã。
Explanation: To connect an ã-adjective to another clause, change the final ã to ããĻ.
2. Practice
Goal: Practice using the grammar in different situations.
Apply the grammar by correcting, transforming, and creating sentences.
đ 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?
ChoicesD
Correct Sentence: ããŽåŗæ¸é¤¨ã¯ãŠãã§ãã。
Explanation: ãŠã means “how” or “what ... like?” and can be followed directly by ã§ãã to ask for an opinion or description. It is not a ãĒ-adjective, so ãĒ cannot be inserted between ãŠã and ã§ã.
2: Which sentence is grammatically incorrect?
ChoicesD
Correct Sentence: äģæŠã¯å¯ããããžããã、å Ŧåã¸čĄããžãã。
Explanation: In polite negative forms of ã-adjectives, 〜ããããžãã already contains the polite ending, so ã§ã is not inserted before the conjunction ã.
3: Which sentence is grammatically incorrect?
ChoicesA
Correct Sentence: įļã¯åŗåæąãįąãããžãã。
Explanation: When an ã-adjective is used with ãã to mean “make something [adjective],” change the final ã to ã, as in įąã → įąããã.
4: Which sentence is grammatically incorrect?
ChoicesD
Correct Sentence: ããã¯įžåŗããéŖãšįŠã§ã。
Explanation: įžåŗãã is an ã-adjective, and ã-adjectives can modify a noun directly without ãĒ, as in įžåŗããéŖãšįŠ. The particle ãĒ is used before nouns with ãĒ-adjectives, such as éããĒå ´æ, so įžåŗãããĒéŖãšįŠ is incorrect.
5: Which sentence is grammatically incorrect?
ChoicesC
Correct Sentence: äģæã¯æããĻ、å Ŧåãčĩ°ããžããã§ãã。
Explanation: To connect an ã-adjective to another clause with 〜ãĻ, change the final ã to ããĻ, as in æã → æããĻ. The past form æããŖã cannot take ãĻ by simply adding it as æããŖããĻ. When the adjective gives the reason or background for a past action, æããĻ can still be used even though the following verb is in the past tense.
✏️ Correct
Find and fix the grammar mistake in the sentence.
Goal: Practice applying grammar rules and producing accurate Japanese sentences.
1: åŗåæąã¯įąããĻ、éŖãšãžãã。
åŗåæąã¯įąããĻ、éŖãšãžãã。
Explanation: To connect an ã-adjective to a following clause, replace the final ã with ããĻ. Therefore, įąã becomes įąããĻ, not įąããĻ.
2: ææĨã¯æ°´ææĨã§ãã ã、åĻæ Ąã¸čĄããžãã。
ææĨã¯æ°´ææĨã§ãã、åĻæ Ąã¸čĄããžãã。
Explanation: To connect a noun sentence politely with ã (“but”), use ã§ãã, not ã§ãã ã. The form ã ã is built from the plain copula ã , while ã§ãã is the corresponding polite form.
3: ãåĨŊãŋįŧãã¯įžåŗãããĻ、å ¨é¨éŖãšãžãã。
ãåĨŊãŋįŧãã¯įžåŗãããĻ、å ¨é¨éŖãšãžãã。
Explanation: To connect an ã-adjective to a following clause, replace the final ã with ããĻ. Therefore, įžåŗãã becomes įžåŗãããĻ, not įžåŗãããĻ.
4: äģæã¯å¯ããĒããĻ、å ŦåãæŠããžãã。
äģæã¯å¯ããĒããĻ、å ŦåãæŠããžãã。
Explanation: To connect the negative form of an ã-adjective to another clause, change 〜ããĒã to 〜ããĒããĻ. Therefore, å¯ããĒã becomes å¯ããĒããĻ, not å¯ããĒããĻ. This form can naturally connect the condition of “not being cold” with the action that follows.
5: åŗæ¸é¤¨ã¯å¤§ãããĒã。
åŗæ¸é¤¨ã¯å¤§ãããĒã。
Explanation: To make an ã-adjective negative, replace the final ã with ããĒã. Therefore, 大ãã becomes 大ãããĒã, not 大ãããĒã. This negative form can be used directly as the predicate of a sentence.
✏️ Rewrite
Rewrite the sentence using the given grammar pattern.
Goal: Practice expressing the same idea using different grammar structures.
1: åŗæ¸é¤¨ã¸čĄããžãã。å Ĩããžããã§ãã。
åŗæ¸é¤¨ã¸čĄããžããã、å Ĩããžããã§ãã。
Explanation: The particle ã connects two clauses while showing a contrast between them. Here, the first clause creates the expectation that going to the library would normally be followed by entering it, but the second clause presents an unexpected or contrasting result. Compared with simply stating the two sentences separately, ~ã、~ makes the relationship between the actions clearer and gives the sentence a smoother, more connected flow.
2: ãåĨŊãŋįŧãã¯įžåŗããã§ã。å ¨é¨éŖãšãžãã。
ãåĨŊãŋįŧãã¯įžåŗãããĻ、å ¨é¨éŖãšãžãã。
Explanation: The ~ããĻ form connects an ã-adjective to what follows, and it can suggest that the first description is related to the following result. Here, įžåŗãã changes to įžåŗãããĻ, giving the nuance that its being delicious naturally led to eating all of it. Compared with stating the ideas separately, this structure makes the cause-and-result relationship feel smoother and more closely connected.
3: ããã¯ãåĨŊãŋįŧãã§ã。įžåŗããã§ã。
ããã¯įžåŗãããåĨŊãŋįŧãã§ã。
Explanation: An ã-adjective can directly modify a noun without changing its form. Here, įžåŗãã describes ãåĨŊãŋįŧã, so the two separate ideas are combined into one noun phrase. This structure is more compact and natural when you want to describe what kind of thing the noun is.
4: į§ã¯åĻįã§ã。åŧã¯äŧį¤žåĄã§ã。
į§ã¯åĻįã§ãã、åŧã¯äŧį¤žåĄã§ã。
Explanation: The particle ã connects two clauses and can show a mild contrast between them. Here, the speaker’s status and the younger brother’s status are different, so ã links the two pieces of information naturally without making the contrast sound too strong. Compared with saying the sentences separately, this pattern makes the comparison between the two people clearer and smoother.
5: ããã¯åŗæ¸é¤¨ã§ã。大ããã§ã。
ããã¯å¤§ããåŗæ¸é¤¨ã§ã。
Explanation: An ã-adjective can be placed directly before a noun to describe it. Here, 大ãã gives information about what kind of library it is, so combining the ideas this way sounds more concise and natural than presenting the description in a separate sentence.
đŦ 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.
Question 1:
A:ããŽéãĢããŊãŗãŗãå
ĨããĻãããã§ãã。
B:ã¯ã。čŗæãå
¨é¨å
Ĩããžã。
A:ããã§ãã。____________。
大ããéã§ãã。
Explanation: After B explains that the bag has enough space for the computer and all the documents, A naturally reacts by commenting on one of its noticeable qualities. The Suggested Answer: 大ããéã§ãã uses 大ãã to describe é, following the target pattern ã-adjective + noun + ã§ã. The particle ã also makes the response sound conversational because A is expressing a new realization based on what B has just said.
Question 2:
A:äģæŠ、å
Ŧåã§æŖæŠããžããã。
B:____________。
A:ããã§ãã。åŽļãĢããžããã。
äģæŠã¯å¯ããĻ、æŖæŠããžãã。
Explanation: A invites B to take a walk in the park, so B needs to give a reason for not wanting to go. The Suggested Answer: äģæŠã¯å¯ããĻ、æŖæŠããžãã connects the condition å¯ã to the following negative action by changing the ã-adjective to its ~ããĻ form, which matches the target grammar N 㯠ã-adj ããĻ~. However, while the meaning is understandable, Japanese more naturally uses ~ããĻ when the second part clearly expresses a result or consequence of the first condition.
Question 3:
A:ããŽãåĨŊãŋįŧãã¯įąãã§ãã。
B:____________。
įąãã§ãã、įžåŗããã§ã。
Explanation: B responds to A’s comment by acknowledging one characteristic of the food and then adding a contrasting positive opinion. The Suggested Answer: įąãã§ãã、įžåŗããã§ã uses ã to connect two contrasting ideas, showing that although the okonomiyaki is hot, it is still delicious. This makes the response fit the context naturally while clearly practicing the target grammar ~ã、~.
Question 4:
A:ããŽãåĨŊãŋįŧãã¯įžåŗããã§ãã。
B:ã¯ã、ã¨ãĻãįžåŗããã§ã。
A:____________。
B:åŗåæąãįžåŗããã§ã。
åŗåæąã¯ãŠãã§ãã。
Explanation: After both speakers agree that the okonomiyaki is delicious, A shifts the conversation to another item on the table and asks for B’s opinion about it. The Suggested Answer: åŗåæąã¯ãŠãã§ãã follows the target pattern N ã¯ãŠãã§ãã, which is used to ask how someone feels about or evaluates a particular thing. B’s reply then fits naturally because it gives a positive opinion about the miso soup.
Question 5:
A:į§ã¯ãŠãŧãĄãŗãéŖãšãžã。
B:ããã§ãã。
A:____________。
B:į§ã¯ãåĨŊãŋįŧããéŖãšãžã。
ããĒãã¯ãŠãã§ãã。
Explanation: After A says what they are going to eat, it is natural to ask B about their choice next. The Suggested Answer: ããĒãã¯ãŠãã§ãã uses the target pattern N ã¯ãŠãã§ãã to shift the topic to B and ask about their situation or preference. Because the topic of food has already been established, the question does not need to repeat “what will you eat,” and B’s answer about choosing okonomiyaki follows naturally.
