确实是city ledger。

在酒店财务里，city ledger就是指非住客的挂账。与transient ledger（前台post账）区分开。city ledger之所以用"city"这个词也是因为大多是用给本地客人，因为住店客人一般都是挂房账(transient ledger)。

in hotel accounting the city ledger is the collection of accounts belonging to non-registered guests. this is distinct from the transient ledger (or front-office ledger or guest ledger) which is the collection of accounts receivable for guests who are currently registered.

the vast majority of accounts in the city ledger are accounts receivable (one notable exception is the advance deposit account discussed below which is an account payable).

included in the city ledger are accounts belonging to various companies that utilize the hotel for meeting space and for lodging travelling executives. instead of billing separately for each individual service that the hotel provides the charges are accumulated in the company's city ledger account. the hotel then periodically sends the bill to the company.

the second major component of the city ledger are credit card accounts. when a guest uses a credit card this transaction creates an account receivable for the hotel to be collected from the credit card company. this account receivable is recorded in the credit card company's city ledger account.

as mentioned above advance deposits are an example of an account payable found in the city ledger. when a guest pays a deposit prior to registration the hotel incurs an account payable to the guest for services to be rendered in the future. advance deposits from all guests are collected in a common advance deposit account. this amount is then transferred back to the guest's front-office account (folio) upon check-in.

现在研二，考研考过两次，英语六级考则考过三次。
虽然我要三次才能通过六级，有些人甚至比我更多次才能通过
但是，我觉得学是考研英语难。
一是考研英语题量比六级要大得多，
二是考研英语语法也比六级多，
三考研英语的句子结构与长度，六级是完全不能比的。
四考研英语的通过比六级的通过率还要低
但多人考不上研，都是英语不过关的。

以您的基础"一年业余时间能有希望通过学位英语考试"有点困难但也不是不可能要过四级需要掌握4200以上的英语词汇能阅读一般的文献有点难度吧 "一天学多少时间 ？怎么学，学什么教材好？" 一天至少两小时用自考教材就可以除了背单词学语法还要多读多听多说买一些双语读物英语听力训练的碟片对你熟悉英语语境找到语感都有帮助. 有了英语语感之后进步就会加快这时再精读语法强化词汇量.然后再去看以前读过的英语文章会发现很多语法问题原来是这样的. 另建议您买一个电子词典上网时您可以用在线翻译其他时候您有空学的时候就可以用随身的电子词典以提高学习效率. 祝您心想事成
