frequency of doing vs frequency to do
- frequency of doing 是正確且常見的用法，用來描述「做某事的頻率」。這裡的
frequency是名詞，後面接介系詞of加上動名詞 (V-ing) 或名詞，構成名詞片語。 - frequency to do 在標準英語中是錯誤的。
Frequency作為名詞，後面不能直接接不定詞 (to + V) 來修飾它。 - 若要表達「做某事的頻率有多高」，應使用 frequency of 或 how frequently 的結構。 EN: The study recorded the frequency of checking social media. 翻譯: 這項研究記錄了查看社交媒體的頻率。

常見錯誤
What are common mistakes with "Frequency"?Which "Frequency" sentences look correct but are wrong?
×The frequency of the earthquake is high.
✓The frequency of earthquakes in this region is high.
「frequency」通常指事件發生的「次數」或「頻率」，而非單一事件的「強度」或「大小」。描述地震時，應使用「frequency」來指地震發生的頻繁程度，而非單次地震的強度。
×He goes to the gym with a high frequency.
✓He goes to the gym frequently / with high frequency.
雖然「with high frequency」在文法上正確，但在描述個人習慣時，使用副詞「frequently」或「often」更為自然。"with high frequency" 較常用於科學、技術或正式統計報告中。
×What is the frequency you visit your parents?
✓How often do you visit your parents? / What is the frequency of your visits to your parents?
在口語或一般詢問中，應使用「How often...?」來詢問頻率。使用「What is the frequency...?」聽起來過於正式或技術性，通常用於詢問具體的統計數據或科學測量。
×The machine's error frequency reduced.
✓The frequency of the machine's errors decreased.
「frequency」本身是一個可數名詞，指「次數」或「頻率」這個度量。錯誤的句子結構容易讓人誤解為「錯誤的頻率」是一種特定類型的頻率。正確說法應明確指出是「錯誤發生的頻率」。
×I don't know its frequency.
✓I don't know how often it happens. / I don't know the frequency (at which it occurs).
在上下文不明確的情況下，單獨使用「its frequency」可能指代不清。應具體說明是什麼的頻率，或使用更口語化的「how often」來表達。
