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: 母は病院へ行きます。

B: 明日は仕事を休みます。

C: 父は会社員です。

D: 私は仕事がします。

Answer
D
Correct Sentence: 私は仕事をします。
Explanation: With する (to do), the thing or activity being done is normally marked with を, so 仕事をします is the natural pattern. が marks the subject of a verb or describes something that occurs or is perceived in expressions such as 音がする (“there is a sound”), but it cannot replace を when 仕事 means the activity that the speaker does.

2: Which sentence is grammatically incorrect?

Choices

A: 今朝、郵便局へ行きました。

B: トイレは階段の右です。

C: 先生は学校を来ます。

D: 父は銀行へ行きます。

Answer
C
Correct Sentence: 先生は学校へ来ます。
Explanation: With 来る (to come), the destination is normally marked by へ or に, as in 学校へ来ます or 学校に来ます. The particle を is not used to mark the destination of 来る; instead, を commonly marks a direct object or a place through which someone moves, as in 道を歩きます.

3: Which sentence is grammatically incorrect?

Choices

A: 友達は映画館へに行きます。

B: 先生は教室へ来ます。

C: 紅茶は要りません。

D: 食堂はエレベーターの隣です。

Answer
A
Correct Sentence: 友達は映画館へ行きます。
Explanation: When indicating a destination with a movement verb such as 行く (to go), Japanese normally uses either へ or に, as in 映画館へ行きます or 映画館に行きます. These particles can often express a similar destination meaning, but they are not combined as へに in this pattern.

4: Which sentence is grammatically incorrect?

Choices

A: 今晩は仕事をしませんです。

B: 父は昨日、病院へ行きました。

C: 母は会社員ではありません。

D: 明日は学校へ行きません。

Answer
A
Correct Sentence: 今晩は仕事をしません。
Explanation: The polite negative form of する (to do) is しません, and this form is already complete by itself.

✅ Choice

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

1: 父は五月五日（　　　　　　）病院へ行きます。

Choices

A: に

B: を

C: へ

D: が

Answer
A
Explanation: The particle に is used with specific points in time, such as exact dates, days of the week, and clock times, to show when an action takes place. Since 五月五日 (May 5th) refers to a specific date, に naturally marks it as the time when the action will happen.

2: 明日は学校へ行きません。学校（　　　　　　）。

Choices

A: へ休みます

B: に休みます

C: を休みました

D: を休みます

Answer
D
Explanation: With 休む, the particle を can mark the school, class, work, or activity that someone is absent from, so 学校を休みます means that the speaker will be absent from school.

3: 母は会社員です。先週、仕事（　　　　　　）。

Choices

A: へしました

B: がしました

C: をしました

D: をします

Answer
C
Explanation: The expression 仕事をする means “to work” or “to do work,” and を marks 仕事 as the object of the verb する. Since 先週 means “last week,” the verb should be in the past form しました.

4: 先生は明日、学校へ（ ）。

Choices

A: 来ります

B: 来きます

C: 来ます

D: 来るます

Answer
C
Explanation: The verb 来る（くる）, meaning “to come,” is an irregular verb, so its polite non-past form is 来ます（きます）. The forms 来ります, 来きます, and 来るます are not valid conjugations in standard Japanese. Since 明日 means “tomorrow,” the non-past polite form 来ます is also appropriate for a future action.

✏️ Correct

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

1: 父は仕事へ休みます。

Answer
父は仕事を休みます。
Explanation: With 休みます, the particle を is used when referring to the activity, work, school, or event that someone takes time off from, as in 仕事を休みます (“take time off work”). The particle へ expresses a direction or destination, so 仕事へ休みます is not grammatical because 休みます does not describe movement toward work.

2: 午後を会議があります。

Answer
午後に会議があります。
Explanation: The particle に is used to mark the specific time when an event takes place, so 午後に indicates that the meeting is in the afternoon.

3: 母は事務へします。

Answer
母は事務をします。
Explanation: With します, the particle を marks the activity or task that someone does, so 事務をします means that the person does office or clerical work. The particle へ marks direction or destination, as in expressions with verbs of movement, so it cannot be used to mark 事務 as the activity being performed.

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: 先週、会議をしました。

B: 先生は学校へ来ませんでした。

C: 昨日、仕事を休むました。

D: 一昨日、銀行へ行きました。

Answer
C
Correct Sentence: 昨日、仕事を休みました。
Explanation: To make the polite past form of a verb, Japanese uses the ます-stem + ました. For 休む (to take a break / be absent), the ます form is 休みます, so the polite past is 休みました. You cannot attach ました directly to the dictionary form 休む, which is why 休むました is ungrammatical.

2: Which sentence is grammatically incorrect?

Choices

A: 先生は明日、学校へ来ます。

B: 新聞は要るません。

C: 友達は銀行へ行きませんでした。

D: 母は先週、仕事を休みました。

Answer
B
Correct Sentence: 新聞は要りません。
Explanation: To form the polite negative of 要る (to need), Japanese uses the ます-stem + ません. The ます form is 要ります, so the negative becomes 要りません.

3: Which sentence is grammatically incorrect?

Choices

A: 祝日は五月三日でした。

B: 会議は八月五日です。

C: 誕生日は七月十日にです。

D: 明日は土曜日です。

Answer
C
Correct Sentence: 誕生日は七月十日です。
Explanation: When a date is used with です to identify when something is, the date is followed directly by です, without に.

4: Which sentence is grammatically incorrect?

Choices

A: 誕生日へデパートへ行きます。

B: これは父の万年筆です。

C: 母は病院へ行きました。

D: 土曜日に仕事を休みます。

Answer
A
Correct Sentence: 誕生日にデパートへ行きます。
Explanation: The particle に is used to mark the time when an action takes place, while へ marks the direction or destination of movement. Since 誕生日 tells us when the person goes somewhere, it should take に, and デパート can take へ because it is the destination.

5: Which sentence is grammatically incorrect?

Choices

A: 受付に椅子があります。

B: 七月十日へ会議をします。

C: 今晩、映画館へ行きます。

D: 弟は会社員ではありません。

Answer
B
Correct Sentence: 七月十日に会議をします。
Explanation: The particle に is used to mark a specific time or date when an action takes place, so a date such as 七月十日 is followed by に.

✏️ Correct

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

1: 父は銀行へ行くました。

Answer
父は銀行へ行きました。
Explanation: To make the polite past form of a verb, you cannot attach ました directly to the dictionary form. For 行く, the polite stem is 行き, so the correct past form is 行きました. The particle へ is correct here because it marks the destination of the movement.

2: 社長は会議がします。

Answer
社長は会議をします。
Explanation: When します means “do” or “hold” an activity, the activity is normally marked by を, so 会議をします means “hold a meeting.” The particle が marks a subject rather than the activity being performed, so it does not work in this pattern with します.

3: 先生は学校へ来ります。

Answer
先生は学校へ来ます。
Explanation: 来る is an irregular verb, so its polite form does not follow the regular -ります pattern. Instead, 来る changes to 来ます（きます） in the polite present/future form. The particle へ is correct because it marks the destination toward which the teacher comes.

4: 母はへスーパー行きます。

Answer
母はスーパーへ行きます。
Explanation: Japanese particles come after the word they mark, so へ must follow the destination noun: スーパーへ. The particle へ marks the direction or destination of movement, and with 行きます, it correctly shows where the mother is going.

5: 先生は学校で来ます。

Answer
先生は学校へ来ます。
Explanation: With a verb of movement such as 来ます, the destination is marked by へ or に, so 学校へ来ます and 学校に来ます are both correct. The particle で usually marks the place where an action is performed, so it cannot mark 学校 as the destination of 来ます in this sentence.
