deflate something vs. deflate
- deflate something 是及物動詞用法，表示「使某物洩氣、放氣」，後面必須接一個受詞（通常是輪胎、氣球、信心等）。

常見錯誤
What are common mistakes with "Deflate"?Which "Deflate" sentences look correct but are wrong?
×The balloon deflated air.
✓The balloon deflated.
「deflate」本身已包含「排出空氣」的意思，為不及物動詞，後面不需要再加「air」作為受詞。
×He deflated the bad news.
✓He was deflated by the bad news.
「deflate」用於比喻「使洩氣、使沮喪」時，通常描述「人」因某事而感到沮喪，常用被動語態（be deflated by）。
×Please deflate the air from the mattress.
✓Please deflate the mattress.
「deflate」的受詞直接是「充氣物體」（如 mattress, balloon, tire），不需要說「deflate the air from...」，這會顯得多餘且不自然。
×The economy is deflating.
✓The economy is experiencing deflation. / Prices are deflating.
在經濟學中，「deflate」作為動詞較少直接用「economy」作主詞。通常說「prices deflate」或使用名詞「deflation」來描述通貨緊縮的經濟狀態。
×I deflated my bike tire to make it flat.
✓I let the air out of my bike tire. / I deflated my bike tire.
「deflate」已表示「放氣」，再說「to make it flat」是多餘的。若要強調結果，可以說「...until it was flat」。
