讨价还价

careful consideration───深思熟虑；细心考虑

take into consideration───顾及；考虑到……

further consideration───进一步考虑

on no consideration───决不；无论如何都不

proper consideration───适当的考虑

under consideration───在考虑之中的

practical consideration───实际的考虑

does not of itself induce the making of a promise does not prevent it from being consideration for the promise.───本身并不能诱发诺言人作出诺言的，并不影响磋商对象成为诺言的对价。

Except as stated in 73 and 74, any performance which is bargained for is consideration.───除73条和74条的规定外，作为磋商对象的任何履行都是对价。

Disparity in value, with or without other circumstances, sometimes indicates that the purported consideration was not in fact bargained for but was a mere formality or pretense.───有或没有其他情景的情况下，价值的不同有时意味着声称的约因在事实上并未经过协商，而只是一种单纯的形式或者伪装。
