Charles Leadbeater: The era of open innovation
TED
“The reason why -- despite all the efforts to cut it down, to constrain it, to hold it back -- why these open models will still start emerging with tremendous force is that they multiply our productive resources, And one of the reasons they do that is that they turn users into producers, consumers into designers.”

用法說明
How is "Constrain" different from similar structures?What usage mistakes are common with "Constrain"?
constrain doing vs constrain to do
- constrain + 名詞 是最常見的用法，表示「限制、約束」某事物或某人。
- constrain + 名詞 + to do 用於表示「迫使或強制某人做某事」，強調外在壓力或限制導致了某種行動。
- constrain + 名詞 + from doing 則表示「限制或阻止某人做某事」，強調阻止某個行動的發生。
- 直接使用 constrain to do（沒有受詞）的結構非常罕見，通常被視為不標準的用法。 EN: The tight budget will constrain our research efforts. 翻譯: 緊縮的預算將限制我們的研究工作。
EN:The tight budget will constrain us to focus on only one project.
翻譯:緊縮的預算將迫使我們只能專注於一個項目。

常見錯誤
What are common mistakes with "Constrain"?Which "Constrain" sentences look correct but are wrong?
×The budget is constrained to increase.
✓The budget is constrained from increasing.
使用 "constrain" 時，表示限制或阻止某事發生，通常搭配 "from + V-ing" 來表示被阻止的動作，而非 "to + V"。"to + V" 通常表示目的或結果，與限制的語意不符。
×We are constrained by time is short.
✓We are constrained by time. / We are constrained because time is short.
"constrain by" 後面應直接接名詞或名詞片語，表示限制的來源。若想表達原因，應使用 "because" 引導子句，或將原因轉為名詞片語（如 "time constraints"）。
×He constrained his anger.
✓He restrained his anger. / He suppressed his anger.
"Constrain" 通常指外在條件、規則或力量迫使某人採取或不採取某行動，或用於抽象事物（如選擇、成長）。控制個人情緒或身體動作，更常用 "restrain"（克制）或 "suppress"（壓抑）。
×The law constrains to protect the environment.
✓The law constrains activities that harm the environment. / The law is designed to protect the environment.
"Constrain" 是及物動詞，後面必須有受詞（被限制的事物）。它不能直接接不定詞（to V）來表示目的。若要表達法律的目的，應使用 "is designed to" 或 "aims to"。
×I feel very constrained.
✓I feel very constrained in this job. / I feel very restricted.
單獨使用 "I feel constrained" 語意不完整，聽者會不清楚在哪方面或被什麼限制。應補充受詞或使用介系詞 "in" 說明情境。口語中，"feel restricted" 可能更為自然。
×The tight deadline constrained us work faster.
✓The tight deadline constrained us to work faster. / The tight deadline forced us to work faster.
"Constrain someone to do something" 是正確結構，表示外在壓力迫使某人做某事，不定詞 "to work" 不能省略。注意，此用法帶有「被迫、不得不」的語意，與單純限制（limit）稍有不同。
