engage

engage和hire都可表示“雇用”。它们的区别在于:

1.engage的宾语只能是人,而hire的宾语可以是物。例如:

We hire out vans by the day.我们的货车按日出租。

I've engaged him as my new assistant.我已聘他为我的新助手。

2.engage的对象一般有一技之长,而hire的对象则可以是“力工”等。例如:

He hires out as a house painter in the summer.他在夏天受雇当房屋油漆工。

He engaged a lawyer to argue his case in court.他请了一位律师来为他出庭辩护。

3.engage所指的雇用时限一般较长,而hire可指短期雇用。例如:

He hired himself to work in the fields for one summer.他曾受雇在田里干一个夏天的活。

He engaged a new secretary.他聘用了一名新秘书。

这组词都有“允诺”的意思。它们的区别是：

promise指作出口头或书面的许诺,但仅指主观意愿,并不暗示一定能实现或有实现的基础; engage指在正式或重大场合用誓言、条约等许下有约束力的诺言或作出可以信赖的保证,尤指订婚; pledge指用行动或言语作出庄严的许诺或正式保证; covenant指订立双方或多方共同遵守的协议; contract指订立慎重并且通常有法律效力的合同或协议。例如:

Our son is engaged to a nice young girl.我们的儿子已跟一位漂亮的女孩订了婚。

I covenant to pay 5000 pounds a year to help rebuild the college.我立约保证每年将付5000英镑帮助重建学院。

They have pledged that any detail given to them will remain confidential.他们已保证,给他们提供的任何细节将予以保密。
