cost用作動詞時,是絕對可以加s
如:Cambridge Online就有一例
Drinking and driving costs lives.(醉酒駕車會喪命)
那為甚麼The car cost him around ten thousand US dollars.的cost並不用costs?
或許:你想到這例句會錯,但其實它絕對正確,只不過,這句是用了過去式,而cost的過去形,或cost的過去分詞,都是cost。
因為購車已是過去的事,所以就用過去形cost.
(注:若cost解作”估算成本,估價”時,過去形才用costed)
希望幫到你!
In this example , the "cost" is vt.(transitive verb及物動詞) the mean is "花費"this sentence's mean is 那車花費了他一萬美元左右~
for another example : We must reduce the production cost.(我們必須降低生產成本) In this situation , this word "cost" is noun (名詞) So the mean is "成本" 而不是 "費用" 要示乎你那句說話的意思來分辨用"cost" or "costs"
