都是”不遺余力“的意思,但是根據(jù)前面的主語的單復(fù)數(shù)來決定后面的”effort"的單復(fù)數(shù)
例如：
We should spare no efforts to further your interests 我們應(yīng)該不遺余力的爭取你的利益
I shall spare no effort to restore world trade by international economic readjustment,
but the emergency at home cannot wait on that accomplishment.
雖然我將不遺余力通過國際經(jīng)濟重新協(xié)調(diào)所來恢復(fù)國際貿(mào)易,但我認(rèn)為國內(nèi)的緊急情況無法等待這重新協(xié)調(diào)的完成.
