1: Which sentence is grammatically incorrect?

Choices
A: æ—Ĩ曜æ—ĨãĢå…Ŧåœ’ã‚’æ•Ŗæ­Šã—ãžã™。
B: åˆåžŒã¯å›ŗæ›¸é¤¨ã§å‹‰åŧˇãŸã„です。
C: こぎã‚ĩãƒŗãƒ‰ã‚¤ãƒƒãƒã‚’ãã ã•ã„。
D: おčŒļã¨ã‚ŗãƒŧãƒŠã¨ãŠãĄã‚‰ãŒåĨŊきですか。
Answer
B
Correct Sentence: åˆåžŒã¯å›ŗæ›¸é¤¨ã§å‹‰åŧˇã—たいです。
Explanation: To express “want to do” in Japanese, attach 〜たい to the ぞす-stem of a verb. The verb 勉åŧˇã™ã‚‹ becomes 勉åŧˇã—ぞす, so its stem is 勉åŧˇã—, and adding たい gives 勉åŧˇã—たい.

2: Which sentence is grammatically incorrect?

Choices
A: į§ã¯į„ŧč‚‰ãŒã„ãĄã°ã‚“åĨŊきと思いぞす。

C: æĨ月はæĩˇå¤–ã¸čĄŒããŸã„ã§ã™。
D: æ˜Ĩはå…Ŧ園が暖かくãĻįļēéē—です。
Answer
A
Correct Sentence: į§ã¯į„ŧč‚‰ãŒã„ãĄã°ã‚“åĨŊきだと思いぞす。
Explanation: Before と思いぞす, a noun or ãĒ-adjective predicate normally takes だ in plain form.

Answer
B
Correct Sentence: äģŠã¯ãŠčŒļがãģしくãĒいです。

4: Which sentence is grammatically incorrect?

Answer
A
Correct Sentence: こぎåģēį‰ŠãŒã„ãĄã°ã‚“å¤§ãã„ã¨æ€ã„ãžã™。

Goal: Practice selecting the correct grammar form according to the context.

1: A:こぎ鞄とそぎ鞄とあぎ鞄がありぞす。ãŠã‚ŒãŒã„ãĄã°ã‚“ä¸ˆå¤Ģですか。 B:こぎ鞄(      )。

Choices
A: ãŒã„ãĄã°ã‚“ä¸ˆå¤Ģです
B: ã¨ããŽéž„ã¨ãŠãĄã‚‰ãŒä¸ˆå¤Ģですか
C: をください
D: がãģしいです
Answer
A
Explanation: The question asks which bag is the most durable among three specific options, so the reply needs to identify one bag as having the highest degree of 丈å¤Ģさ. The pattern N ãŒã„ãĄã°ã‚“ + adjective is used to say that N has the greatest degree of a quality within a group.

2: 前回ぎčŠĻ合は掋åŋĩでした。åŊŧは毎æ—ĨᎴįŋ’しãĻいぞすから、æŦĄå›žã¯å¤§ä¸ˆå¤Ģ(      )。

Choices
A: ですと思いぞす
B: だと思いぞす
C: でと思いぞす
D: ãĒと思いぞす
Answer
B
Explanation: Before と思いぞす, Japanese normally uses the plain form. 大丈å¤Ģ behaves like a ãĒ-adjective, so its plain affirmative form is 大丈å¤Ģだ, making 大丈å¤Ģだと思いぞす the appropriate pattern.

3: åē—å“Ą:ノãƒŧトとボãƒŧãƒĢãƒšãƒŗãŒã‚ã‚Šãžã™。 åŽĸ:ノãƒŧトとボãƒŧãƒĢãƒšãƒŗ(      )ください。

Choices

B: が
C: を
D: で

✏️ Correct

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

1: į´…čŒļã¨ã‚ŗãƒŧヒãƒŧã¨ãŠãĄã‚‰ã‚’åĨŊきですか。

Answer
į´…čŒļã¨ã‚ŗãƒŧヒãƒŧã¨ãŠãĄã‚‰ãŒåĨŊきですか。
Explanation: With åĨŊきです, the thing or person you like is normally marked with が, because åĨŊき is a ãĒ-adjective meaning “liked/favorite,” rather than a transitive verb that takes an object with を.

2: åŊŧはæŦĄå›ž、勝たãĒいだと思いぞす。

Answer
åŊŧはæŦĄå›ž、勝たãĒいと思いぞす。
Explanation: Before と思いぞす, verbs in the plain form connect directly without だ. Since 勝たãĒい is already the plain negative form of 勝つ, it should be followed directly by と思いぞす. The copula だ can appear with nouns and ãĒ-adjectives.

3: 昨æ—Ĩ、ã‚ąãƒŧã‚­ã‚’éŖŸãšãŸã„ããĻ、å–ĢčŒļåē—ã¸čĄŒããžã—ãŸ。

Answer
昨æ—Ĩ、ã‚ąãƒŧã‚­ã‚’éŖŸãšãŸããĻ、å–ĢčŒļåē—ã¸čĄŒããžã—ãŸ。
Explanation: The 〜たい form behaves like an い-adjective, so when it is connected with 〜くãĻ, the final い changes to くãĻ: éŖŸãšãŸã„ → éŖŸãšãŸããĻ.
