实例：
Private law can be divided into six major branches according to the kinds of legal rights and obligations involved.These branches are(1)contract and commercial law,(2)tort law,(3)property law,(4)inheritance law,(5)family law,and(6)corporation law.
译文：
按照所调整的法律权利与义务种类的不同，私法可以分为6个部门法。它们是（一）合同与商法，（二）侵权法，（三）财产法，（四）继承法，（五）家庭法，以及（六）公司法。

由于标准不同，合同可以分为：bilateral contract（双务合同）与unilateral contract（单务合同）；express contract（明示合同）与implied contract（默示合同）；quasi contract or contract implied in law（准合同或法律推定合同）；executed contract（已履行的合同）与executory contract（未履行的合同）；valid contract（有效合同）与void contract（无效合同）、voidable contract(可撤销合同)、unenforceable contract（不可强制履行的合同），等等。
Contract（合同）与agreement（协议）的区别：合同一定是协议，但协议不一定能成为合同，因为合同的成立需具备一定的条件。
例句：
The vast majority of contracts are bilateral contracts——that is,they consist of reciprocal promises.
英译汉：
Each party to a bilateral contract makes a promise,is obligated to perform as promised,and has a right to expect the other party to perform.
