ideal for doing vs ideal to do
- ideal for doing 強調某物或某種情況是進行某項活動的「完美環境、工具或時機」。介系詞
for後面接名詞或動名詞 (V-ing)。 - ideal to do 強調在特定情況下，採取某個行動是「最完美、最合適的選擇」。形容詞
ideal後接不定詞 (to + V)，常與It is...句型連用。 - 當主詞是
it（虛主詞），指代後面的不定詞片語時，幾乎總是使用 ideal to do 的結構。 - 若主詞是具體的人、事、物，且後方直接說明其用途，則使用 ideal for (doing)。 EN: This quiet corner is ideal for studying. 翻譯: 這個安靜的角落是讀書的理想地點。
EN:It is ideal to study in a quiet corner.
翻譯:在安靜的角落讀書是最理想的。

常見錯誤
What are common mistakes with "Ideal"?Which "Ideal" sentences look correct but are wrong?
×He is an ideal.
✓He is an ideal person.
「ideal」作為形容詞，不能單獨用作名詞來指人。必須與名詞連用，如「ideal candidate」、「ideal partner」。
×This weather is ideal very for a picnic.
✓This weather is ideal for a picnic.
「ideal」本身已表示「最完美的、最理想的」，前面不需要再加「very」來修飾。使用「absolutely ideal」或「perfectly ideal」是可以的，但單獨的「very ideal」不自然。
×My ideal is to become a doctor.
✓My ideal is to help people. / My goal is to become a doctor.
「ideal」作名詞時，指的是「理想的原則、標準或典範」，通常是抽象概念，而非具體的職業目標。表達具體的「目標」應使用「goal」、「aim」或「dream」。
×This tool is ideal to fix cars.
✓This tool is ideal for fixing cars.
表達「對做某事而言是理想的」，常用結構是「ideal for + noun/gerund」，而不是「ideal to + verb」。
×Option A is more ideal than Option B.
✓Option A is better/more suitable than Option B.
「ideal」在嚴格的用法中是一個「絕對形容詞」，表示「完美的、最理想的」，因此通常不用比較級（more ideal）或最高級（most ideal）。在非正式語境中雖有使用，但學習者應優先使用「better」、「more suitable」或「closer to ideal」。
×It is an ideal exactly location.
✓It is an ideal location. / It is exactly the ideal location.
修飾語「exactly」的位置錯誤。它應該修飾整個名詞片語「ideal location」，通常放在冠詞前或動詞後，而不是插入在形容詞和名詞之間。
