reduced by 和 reduced to的不同?

Question

reduced by 和 reduced to 的用法有哪些不同?還是一樣?

已更新項目:

若有一物件高度100cm，It is reduced in height by 60%，

那麼剩下的高度是40cm囉???還是60cm???

Answer 1

最佳解答

這兩個用法不太一樣

這樣解釋最快:

500 reduced by 300 跟 500 reduced to 300 有什麼不同?

500 reduced by 300

==> equals 200.

(500-300=200)

這個跟 500 is reduced to 200 一樣.

500 is reduced to 300.

(500 ==> 300, so 500-200=300)

這個跟 500 is reduced by 200 一樣.

這樣的解釋清楚嗎?

補充;

若有一物件高度100cm，It is reduced in height by 60%，

那麼剩下的高度是40cm囉???還是60cm???

reduced [in height] by 60% ==> 60% of 100 cm = 60cm

所以就是 reducded by 60cm

100 cm reduced by 60 cm (100cm-60cm = 40cm)

剩下的高度是40cm.

Or you can say,

reduced in height TO 40%. 就是剩下40% (40cm)

reduced by 是指因什麼事或物或人而減少，by的後面是接該事或該物或該人

如 my salary was reduced by my boss.

reduced to 減少到何程度，如my salary was reduced to only NTD$10000 per month.
