用法說明
How is "Accelerate" different from similar structures?What usage mistakes are common with "Accelerate"?
accelerate doing vs accelerate to do
- accelerate doing 強調「加快一個正在進行或持續的過程或活動」。動名詞 (doing) 在這裡作為受詞，指稱該活動本身。
- accelerate to do 則表示「為了達成某個特定目的或結果而加快速度」。不定詞 (to do) 帶有目的性，指加快後要去做的事情。
- 在描述「加速某個程序、專案或行動」時，通常使用 accelerate doing 或直接接名詞 (如 accelerate the process)。
- 在較正式的商業或技術文件中，accelerate to do 的結構較少見，目的性通常由上下文或介系詞片語 (如 to meet deadlines) 表達。 EN: The company decided to accelerate developing the new software. 翻譯: 公司決定加快開發新軟體。
EN:The car accelerated to pass the truck before the lane ended.
翻譯:汽車加速以在車道結束前超越卡車。
總結建議
一般情況下，表示「加快某項工作或過程」時，使用 accelerate + 名詞 或 accelerate doing 較為自然；而 accelerate to do 則用於明確表達「加速是為了去做另一件事」的目的。

常見錯誤
What are common mistakes with "Accelerate"?Which "Accelerate" sentences look correct but are wrong?
×The company decided to accelerate their production.
✓The company decided to accelerate its production.
當主詞是單數名詞（如 company, car, process）時，其所有格應使用單數形式（its, his, her），而非複數形式（their）。
×He accelerated to run faster.
✓He accelerated to run faster. / He sped up to run faster.
雖然語意上可理解，但 'accelerate' 通常用於車輛、過程或變化速率，描述人體跑步速度加快時，使用 'speed up' 或 'increase his speed' 更為自然。'Accelerate' 用於人時略顯正式或不自然。
×We need to accelerate the process more quickly.
✓We need to accelerate the process.
'Accelerate' 本身已含有「加快速度」的意思，加上 'more quickly' 會造成語意重複（冗言）。應直接使用動詞即可。
×She accelerated her English learning.
✓She intensified her English learning. / She sped up her English learning progress.
'Accelerate' 通常用於具體的過程、速度或發展，如 'accelerate growth', 'accelerate the car'。用於像 'learning' 這類抽象活動時雖可理解，但 'intensify'（加強）或 'speed up the progress of'（加快進度）是更常見、自然的搭配。
×The inflation rate was accelerated last year.
✓The inflation rate accelerated last year.
'Accelerate' 在此作為描述速率變化的不及物動詞，主詞（inflation rate）本身會加速，不應使用被動語態。被動語態常用於及物用法，如 'Growth was accelerated by new technology.'（成長被新科技加速了）。
×He made the car accelerate.
✓He made the car accelerate. / He accelerated the car.
雖然文法正確，但 'make something accelerate' 的結構較為冗長。在大多數情況下，直接使用 'accelerate' 作為及物動詞（accelerate the car）更為簡潔自然。
