選択肢の解説Choice Analysis

isn't it

正解

"The new downtown art museum is genuinely impressive, ~" は肯定主節を受ける否定タグ = 「isn't it」: 肯定文 + 否定の付加疑問 (助動詞 + n't + 代名詞)。be 動詞 is なら isn't、主語 the museum → it。ポイント: 極性一致の原則 = 肯定→否定 / 否定→肯定。同意確認・念押しの典型。準1級頻出: タグの極性反転は C1 鉄板、会話の自然さで必出。

  • is it

    = 肯定タグ ━ 肯定主節には否定タグが要る ━ 肯定→否定の反転が原則、is it は反転していない。

  • isn't he

    = 主語誤り ━ the museum は it ━ 主語 the museum は it、人称 he は不一致。

  • wasn't it

    = 過去形タグ ━ is と時制不一致 ━ 主節は現在 is、タグも現在 isn't が必要。

✅ なぜ「isn't it」が正解? この文では肯定主節 (is impressive) を念押しで受けるので極性反転の 「isn't it」 が正解。is it は肯定タグで極性が反転せず誤り、isn't he は主語 it を he と取り違え、wasn't it は時制が現在 is と食い違う。

否定文, 肯定タグ? = 主節が否定なら付加疑問は肯定。n't を外して助動詞を反復。

選択肢の解説Choice Analysis

did they

正解

"The disappointed investors did not actually receive any of the promised returns, ~" は否定主節を受ける肯定タグ = 「did they」: 否定文 (did not) + 肯定の付加疑問 (助動詞 + 代名詞、n't なし)。主語 investors → they。ポイント: 否定→肯定の反転。did not の did をそのまま肯定タグに反復する。準1級頻出: 否定主節の肯定タグは C1 鉄板、極性判断の核心。

  • didn't they

    = 否定タグ ━ 否定主節には肯定タグが要る ━ 否定→肯定の反転が原則、didn't は二重否定で誤り。

  • did it

    = 主語誤り ━ investors は they ━ 複数主語 investors は they、it は不一致。

  • do they

    = 現在形タグ ━ did と時制不一致 ━ 主節は過去 did not、タグも過去 did が必要。

✅ なぜ「did they」が正解? この文では否定主節 (did not receive) を受けるので極性反転の肯定タグ 「did they」 が正解。didn't they は否定タグで二重否定となり反転していない、did it は主語 investors を it と取り違え、do they は時制が過去 did と食い違う。

助動詞反復のタグ (will / can / should など)

ひとことで

主節の助動詞をそのままタグに反復。will→won't, can→can't, should→shouldn't と極性反転。

選択肢の解説Choice Analysis

won't you

正解

"You will definitely remember to lock the front door before you finally leave tonight, ~" は助動詞 will を反復する否定タグ = 「won't you」: 主節に助動詞があればその助動詞をタグに反復。will (肯定) → won't (否定タグ)、主語 you → you。ポイント: do/does/did を補わず、主節の助動詞そのものを使う。極性は反転。準1級頻出: 助動詞反復のタグは C1 鉄板、法助動詞の念押しで必出。

  • will you

    = 肯定タグ ━ 肯定主節には否定タグが要る ━ 肯定→否定の反転、will you は反転していない。

  • don't you

    = do の補充 ━ 助動詞 will を反復すべき ━ 主節に will があるので won't、do は不要。

  • wouldn't you

    = would へのすり替え ━ will と法・時制不一致 ━ 主節は will、タグも will 系 won't が必要。

✅ なぜ「won't you」が正解? この文では肯定主節の助動詞 will を反復し極性反転するので 「won't you」 が正解。will you は肯定タグで反転しておらず、don't you は助動詞 will を無視して do を補っており誤り、wouldn't you は will を would にすり替えて時制・法がずれる。
