N4 Grammar · Test 49

いけませんね is the correct response. When someone tells you they are sick (fever, headache), a natural sympathetic reply is 'それはいけませんね' meaning 'That's too bad / That's awful.' いけません is the negative potential form of いける (to be acceptable / to be okay), and here it expresses concern: 'that's not good.'

• 1おげんきで means 'please stay healthy' and is used as a farewell wish when someone is leaving or in letters. It is completely inappropriate when someone has just told you they are sick.
• 3かしこまりました means 'certainly / I understand' and is a polite formula used by shop staff or subordinates accepting an order or request. It does not fit a conversation about illness.
• 4しつれいします means 'excuse me' and is used when entering/leaving a room or ending a phone call. It is not a sympathetic reply to someone reporting illness.

• いけません — that's no good; that's bad (expression of concern)
• おげんきで — please take care of yourself (farewell greeting)
• かしこまりました — certainly; I understand (polite acceptance)
• しつれいします — excuse me (polite leave-taking)

までに means 'by (a deadline),' indicating the latest time before which an action should be completed. 「9時までに来てください」= 'Please come by 9 o'clock.' Since coming to the classroom is a one-time action with a deadline, までに is correct.

• 1まで means 'until (a time),' indicating a continuous action or state that lasts until that time. 9時まで来てください would imply 'keep coming until 9,' which is unnatural for a single arrival.
• 3までは means 'until (time) (contrastive).' It emphasizes the boundary but still carries the 'until' sense of continuous action, which does not fit a one-time arrival instruction.
• 4までで is not a standard grammatical pattern for deadlines. で after まで would mark means/location, which is not appropriate here.

• までに — by (a deadline); before or at a specified time
• 教室きょうしつ — classroom

ばかり means 'only / nothing but.' 「知っていることばかりで」= 'it was nothing but things I already knew,' explaining why the talk wasn't interesting. The pattern 「～ばかりで」expresses that something consists entirely of one type of thing, often with a negative nuance.

• 1しか is used with a negative predicate to mean 'only' (～しかない). Here the sentence ends with おもしろくなかった, but しかで is not a standard connective form, and the structure doesn't match.
• 3ほど means 'to the extent of' and is used in comparisons (XはYほど～ない). It does not mean 'only' and would not fit here.
• 4より means 'than' and is used in comparisons (XよりYのほうが). It does not express 'only/nothing but' and would not fit the sentence.

• ばかり — only; nothing but (often with negative nuance)
• 知しっている — to know (something)

The sentence means 'Yesterday, my friend came, so I couldn't study.' ので (node) connects a cause/reason to its result. 友だちが来たので = 'because my friend came.' It is used within a single sentence to link the cause clause to the effect clause.

• 1でも (demo) means 'but/however.' It would connect two clauses with a contrastive relationship, not a cause-effect one. 'My friend came, but I couldn't study' doesn't make logical sense here since the friend's visit is the reason.
• 2だから (dakara) means 'so/therefore,' but it is a sentence-initial conjunction used to start a new sentence (友だちが来た。だから、勉強ができませんでした). It cannot be used as a connective particle within one sentence like ので.
• 4ように (yō ni) means 'so that / in order to.' It expresses purpose, not cause. 'My friend came in order to (I) couldn't study' makes no sense.

• ので — because, so (connects cause to result within a sentence)
• でも — but, however
• だから — so, therefore (sentence-initial)
• ように — so that, in order to

The sentence means 'I put in a lot of sugar, but it's still not sweet.' のに (noni) expresses 'even though / despite.' It connects a situation that would normally lead to an expected result with a contrary outcome. 入れたのに = 'even though I put in (a lot of sugar).' The まだ ('still') in the second clause reinforces the unexpectedness.

• 1ばかり (bakari) means 'just / only / nothing but.' 入れたばかり would mean 'just put in' or 'only put in,' which doesn't connect logically to 'it's still not sweet.'
• 2とか (toka) means 'such as / or,' used to list examples. It has no place in this cause-contrast sentence.
• 3から (kara) means 'because.' Using it would say 'Because I put in a lot of sugar, it's not sweet' — the cause-effect is backwards and illogical.

• のに — even though, despite (expresses contrary expectation)
• ばかり — just, only, nothing but
• さとう — sugar
• あまい — sweet

The sentence means 'I borrowed an umbrella from my friend and forgot to return it (kept it as-is).' 〜まま (mama) means 'leaving something in a certain state / as it is.' かりたまま = 'in the state of having borrowed it (without returning it).' This perfectly describes keeping something borrowed without returning it.

• 1あいだ (aida) means 'while / during (a period).' かりたあいだ is not grammatical in this pattern; あいだ typically follows a verb in 〜ている form or a noun + の.
• 3だけ (dake) means 'only.' かりただけ = 'only borrowed,' which doesn't convey the meaning of leaving something in an unchanged state.
• 4ながら (nagara) means 'while doing / although.' かりたながら is ungrammatical; ながら requires the stem (pre-masu form) of a verb, not the た-form.

• 〜まま — as it is, leaving something in a certain state
• あいだ — while, during
• だけ — only
• ながら — while doing, although
• かす — to lend (borrower's perspective: かりる)
