对新PREP里面一道题解释很不解，强力求助版主大牛一枚，貌似无前人解决

DUKB24

Introduced by Italian merchants resident in London during the sixteenth century,in England life insurance remained until the end of the 17th century a specialized contract between individual underwriters and their clients,typically being ship owners,overseas merchants,or professional moneylenders.
A.in England life insurance remained until the end of the 17th century a specialized contract between individual underwriters and their clients,typically being
B.in England life insurance had remained until the end of the 17th century a specialized contract between individual underwriters with their clients,who typically were
C.until the end of the 17th century life insurance in England had remained a specialized contract between individual underwriters and their clients,typically
D.life insurance in England remained until the end of the 17th century a specialized contract between individual underwriters and their clients,typically
E.life insurance in England remained until the end of the 17th century in England a specialized contract between individual underwriters with their clients,who typically were这道题答案选D，解释里说a contract 做life insurance的同位语，但是，同位语与其所修饰的名词之间不应该有逗号吗？也就是说，17th  century 和 a specialized contract中间是不是应该有一个逗号？...当时我限时做的时候我就看成life insurance remained a special contact了...真特么蛋疼，求助NN版主

是表语吧，remain做系动词

johnwolf

确实是宾语，题干的最后部分才是同位语

jinertia

是宾语

DUKB24

umm,今天再看回来确实觉得这个specialized contract是宾语

查了longman里面也有类似的用法可以接名词：


we remained friends（这是longman给出的例句）

UP!

反正我看到这里是百思不得其解了

也许，是想说 insurance 和 contract 是对应的意思。明显这里不是同位语呀。估计是解释的人没有表达好自己的意思。

DUKB24

我不懂为什么那个是同位语。答案倒是没有争议

逗号分开的修饰语 要遵循touch rule
