用法說明
How is "Investment" different from similar structures?What usage mistakes are common with "Investment"?
investment in doing vs investment to do
- investment in doing 通常用於描述將資源（金錢、時間、精力）投入到一個持續的、過程性的活動或領域中，強調的是對某個領域或活動的長期投入。
- investment to do 則常指為了達成某個特定目的、目標或結果而進行的投資，強調投資的「目的性」和「未來結果」。
- 在談論對公司、專案或資產的財務投資時，兩者有時可互換，但細微差別在於：investment in 側重於「投資於某個實體」，而 investment to 側重於「為了達成某個目的而投資」。 EN: The company made a significant investment in developing renewable energy technology. 翻譯: 該公司投入巨資開發可再生能源技術。
EN:We need a major investment to expand our operations into Asia.
翻譯:我們需要一筆重大投資，以將業務擴展到亞洲。
總結建議
一般情況下，描述對某個領域、活動或資產的投入時，使用 investment in doing；而強調為了達成特定目標或取得某樣東西而投資時，則使用 investment to do。

常見錯誤
What are common mistakes with "Investment"?Which "Investment" sentences look correct but are wrong?
×He made an investment on stocks.
✓He made an investment in stocks.
The correct preposition to use with 'investment' is 'in', not 'on' or 'at'. This is a fixed collocation.
×It is a good investment to buy this house.
✓Buying this house is a good investment. / This house is a good investment.
The structure 'It is a good investment to + verb' is unnatural. Use a gerund as the subject or make the object the subject of 'is'.
×We need more investments for the new project.
✓We need more investment for the new project.
'Investment' is usually an uncountable noun when referring to the general concept or activity of investing money. The plural form 'investments' is used when referring to specific instances or multiple distinct items invested in.
×The investment of time is worth it.
✓The investment in time is worth it.
When 'investment' refers to spending time/effort (not money), the preposition 'in' is still used, not 'of'. 'Of' can be used in structures like 'an investment of $1000', specifying the amount.
×This software is an investment to improve productivity.
✓This software is an investment that will improve productivity. / Investing in this software will improve productivity.
Using an infinitive ('to improve') directly after 'an investment' to state its purpose is awkward. Use a relative clause ('that will improve') or rephrase the sentence.
