Read each pattern and its example, then write your own sentence on the line.
〜だけあって N / V-dict / V-ta / i-adj / na-adj な + だけあって
Says a good result matches the reason given: as you'd expect from that status, training or reputation. Used for praise, so avoid it for bad outcomes. Neutral; common in speech and writing.
彼は留学しただけあって、英語の発音がきれいだ。 As you would expect from someone who studied abroad, his English pronunciation is beautiful.
〜どころか N / V-dict / V-ta / i-adj / na-adj な + どころか
Denies the first idea and gives a far stronger opposite: not just not A, but even B. Carries surprise or complaint. Used in both speech and writing.
彼は漢字どころか、ひらがなも読めない。 Far from kanji, he can't even read hiragana.
〜どころではない N / V-dict + どころではない（どころじゃない）
Says the situation makes something impossible or inappropriate right now: this is no time for that. Stronger and more emotional than できない. Common in everyday speech.
締め切り前で、旅行どころではない。 With the deadline coming up, this is no time for a trip.
〜ものの V / i-adj plain + ものの；na-adj な・である + ものの；N である + ものの
Concedes that something is true, then says the expected result did not follow. Close to けれど but stiffer; mainly written and formal speech.
引き受けたものの、自信はない。 I took the job on, but I have no confidence.
〜ものだ V-ta + ものだ（回想）／V-dict・V-nai + ものだ（常識）／i-adj い・na-adj な + ものだ（感嘆）
Three uses: V-ta ものだ for nostalgic habits, V-dict/V-nai ものだ for social common sense (one ought to), and adjective + ものだ for exclamation. Slightly literary but common in speech.
子供のころ、よくこの川で泳いだものだ。 When I was a child, I used to swim in this river a lot.
〜ものだから V / i-adj plain + ものだから；na-adj な + ものだから；N な + ものだから
Gives a reason as an excuse or explanation, often for something the speaker regrets. Sounds personal and apologetic; spoken, with もんだから as the casual form.
電車が遅れたものだから、会議に間に合わなかった。 The train was delayed, so I couldn't get to the meeting on time.
