N5 Grammar · Test 45

The pattern V-ます stem + たい means 'want to do X.' The stem (ren'yōkei) of およぐ is およぎ, so およぎたい means 'want to swim.' The sentence says 'I want to swim at the beach in summer.'

• 1およぐ is the dictionary form. たい attaches to the V-ます stem, not the dictionary form. You cannot say およぐたい.
• 2およい is not the correct stem of およぐ. The verb およぐ conjugates as およぎます, so the stem is およぎ, not およい.
• 3およが is the provisional/conditional stem (未然形), used with う/よう (およごう) or ない (およがない). It is not used with たい.

• 泳およぐ — to swim
• 夏なつ — summer
• 海うみ — sea, beach
• 〜たい — want to do ~

The pattern being tested is the な-adjective + なる (to become). For な-adjectives like じょうぶ, you drop な and add く to form the adverbial, then attach なる: じょうぶ＋く＋なります = 'became healthy/strong.' The sentence means 'My body became strong/healthy.'

• 1じょうぶな is the pre-noun form (連体形) of the な-adjective, used before a noun (e.g., じょうぶなからだ). It cannot connect to なりました.
• 2じょうびに is a deliberate lookalike distractor. じょうび (誕生日・生日) means 'birthday' and is an entirely different word. It does not fit grammatically or semantically.
• 4じょうぶで is the て-form of the な-adjective, used to link clauses or for reasons (e.g., じょうぶで元気です). It cannot precede なりました in this pattern.

• じょうぶ — healthy, strong, sturdy
• なる — to become

The sentence uses a parallel/contrast structure: これは日本語のじしょで、あれは英語のじしょです ('This is a Japanese dictionary, and that is an English dictionary'). The て-form of です (で) links the two clauses, expressing a simple connection/contrast. This is the 〜で、〜 pattern for connecting two noun-predicate sentences.

• 1じしょや uses や, which means 'and' for an incomplete list of nouns (AやB). It would require another noun after it and does not connect two full clauses.
• 2じしょと uses と, which means 'and' for a complete list of nouns. Like や, it connects nouns, not clauses, so it cannot link これは日本語のじしょ to the second clause.
• 4じしょが uses が, the subject marker. これは日本語のじしょが would be ungrammatical here because は already marks これ as the topic.

• じしょ — dictionary
• で — te-form of です, linking two clauses

Here から means 'from' (temporal origin) and も means 'also/even.' The sentence is: このしんぶんはおとといの(しんぶん)からもいりません = 'I don't need this newspaper, nor do I need the one from the day before yesterday.' おとといの modifies an implied しんぶん, and から indicates 'from (that day).' The structure is Noun+の+から+も+いりません.

• 2おとといのだ would make から a conjunction meaning 'because': おとといのだからもいりません = 'Since it's from the day before yesterday, I don't need it.' While grammatically possible, the も ('also/even') is unnatural in this reading, and the intended pattern uses から as 'from' with も.
• 3おとといので would create ので (because/since), a conjunction. おとといなので + もいりません is awkward because ので already provides the reason and も doesn't fit naturally. Also, ので is a single conjunction and splitting it this way is not standard.
• 4おとといだった would make から a conjunction: おとといだったからもいりません = 'Since it was the day before yesterday, I don't need it.' Again, the も is unnatural here, and the intended reading uses から as 'from.'

• おととい — the day before yesterday
• しんぶん — newspaper
• いる（要る） — to need

はやくして is the correct form. はやく is the adverbial form of the い-adjective はやい, and して is the て-form of する. はやくしてください means 'please hurry up' or 'please make it quick.' The pattern 〜くして + ください requests that someone do something in a certain manner.

• 2はやくになって is ungrammatical. はやくなる (to become early/fast) would be the correct intransitive form for an い-adjective, but はやくになる is not standard, and になってください ('please become early') is semantically odd—you cannot ask someone to 'become' early.
• 3はやいにして is ungrammatical. The い-adjective stem はやい cannot be followed by にして in this way. The correct adverbial form is はやく, not はやいに.
• 4はやいになって is doubly wrong: はやい should be はやく (adverbial), and になって is the wrong verb form for this request pattern.

• はやい（早い/速い） — early, fast
• 〜くする — to make something ~ (adverbial form of い-adjective + する)

The pattern being tested is the な-adjective + なる (to become). For な-adjectives like じょうぶ, you drop な and add く to form the adverbial, then attach なる: じょうぶ＋く＋なります = 'became healthy/strong.' The sentence means 'My body became strong/healthy.'

• 2おとといのだ would make から a conjunction meaning 'because': おとといのだからもいりません = 'Since it's from the day before yesterday, I don't need it.' While grammatically possible, the も ('also/even') is unnatural in this reading, and the intended pattern uses から as 'from' with も.

• はやい（早い/速い） — early, fast
• 〜くする — to make something ~ (adverbial form of い-adjective + する)
