assure / promise / guarantee 的区别

assure
ensure
guarantee
promise
这组字的意思是要消除疑虑,借以使人对某些事觉得确实或可靠,都是保证、担保的意思.
【Assure】可以表示证实或使人觉得确实.
例如:The doctor assured him that his child would recover from the illness(医生向他保证说他的孩子会痊愈);
The fact that the hospital had a good reputation assured him that his child would be well taken care of(该医院声誉良好,使他确信孩子将受到妥善的照顾).
【Ensure】可拼作insure,它的意思是保证某些行动或者媒介获得结果.
例如:To ensure the child's quick recovery,the doctor gave him an antibiotic(为确保那孩子获迅速痊愈,医生给他注射抗生素).
Ensure也有保障,防受伤害的意思.
例如:to ensure freedom against tyranny(保障反抗暴政的自由).
【Guarantee】的意思是指对产品质素或履行服务或义务负起责任的保证.
Guarantee一项债务的人,assure债主一定获得付款.
【Promise】像assure一样,往往是指设法令人觉得稳当可靠,但是并不guarantee结果必如所期.Promise是应承的意思,只表示自己的意向,而非负起义务,连小孩子都知道并不是一切诺言都受人遵守.
例如:to promise someone a rise in pay(答应给某人加薪);
to promise to keep an appointment(应允践约)
在另一意义上,promise只表示有乐观理由.病人回复胃口可视为promising迹象.
