Side account means an account that is associated with or part of a
contract, intended to hold amounts in excess of the maximum amount permitted to
be held under an exempt contract.Limit on funds held under exempt contract.
显然上述句子承前省略了a contract，应该是Side account means an
account that is associated with a contract or part of a contract但是我同时注意到这里还错误省略了一个is，完全补全后应该是Side account
means an account that is associated with a contract or is part of a contract 根据章振邦的观点，前个is是构成被动语态，后一个is是系动词，是不能省略的，但是我们在阅读中经常可以见到这样省略，这是为什么？
