用法說明
How is "Understand" different from similar structures?What usage mistakes are common with "Understand"?
understand doing vs understand to do
- understand doing 表示理解「做某事」這個事實或概念，通常用於描述理解一個既存的行為、情況或過程。
- understand to do 並非標準的英語搭配。動詞 "understand" 通常不直接接 "to + 動詞原形" 來表示「理解去做某事」。
- 若要表達「理解到（自己）應該做某事」或「經告知而明白要做某事」，會使用被動結構 be understood to do 或搭配名詞子句 understand that...。
- 表達「理解如何做某事」時，會使用 understand how to do。 EN: I can't understand refusing to help a friend in need. 翻譯: 我無法理解拒絕幫助需要幫忙的朋友這種行為。
EN:The committee members are understood to submit their reports by Friday.
翻譯:委員會成員被要求（大家理解他們應該）在週五前提交報告。
總結建議
一般情況下，使用 "understand doing" 來表達理解某個行為或事實，而應避免直接使用 "understand to do" 的主動結構。
易混淆對比

understand vs realize

EN:It's just not working out, understand?
翻譯:這樣就是行不通，懂嗎？

常見錯誤
What are common mistakes with "Understand"?Which "Understand" sentences look correct but are wrong?
×I am understanding the problem now.
✓I understand the problem now.
"Understand" 是一個狀態動詞 (stative verb)，通常不用進行式。應使用簡單現在式來表達當下的理解狀態。
×I understood what you mean.
✓I understand what you mean.
當談論說話當下或目前的理解狀態時，應使用現在式 "understand"。過去式 "understood" 用於描述過去某個時間點的理解，與現在無關。
×I understand to speak English.
✓I understand how to speak English. / I understand spoken English.
"Understand" 後面不直接接不定詞 "to do"。若要表達理解「如何做某事」，應使用 "understand how to..."。若要表達理解某種語言，則直接接名詞或動名詞片語。
×I am not understanding.
✓I don't understand.
否定句同樣不應使用進行式。狀態動詞的否定形式通常使用助動詞 "do/does/did" + not + 動詞原形。
×Can you explain me? I'm not understanding.
✓Can you explain it to me? I don't understand.
這是一個常見的組合錯誤。首先，"explain" 需要接事物作受詞，若要表達向某人解釋，應使用 "explain something to someone"。其次，如前所述，"understand" 不應用進行式。
×I very understand.
✓I understand very well. / I completely understand.
副詞 "very" 通常不用來直接修飾動詞。修飾 "understand" 時，應使用 "very well"、"completely"、"fully" 等副詞片語，並置於動詞之後或句末。
