问题如下：
Scenery manufacturer is a US-based company, Scenery has a subsidiary, XZZ, operates in CHINA, XZZ was acquired in 2018 and has never paid a dividend. It records inventory using the FIFO method. RMB is expecting depreciation in the future.
Compared with using the RMB as XZZ’s functional currency for 2018, if the US dollar were the functional currency, it is most likely that Scenery’s consolidated:
选项：
A.Gross profit margin will be higher
B.A/R turnover is higher
C.current ratio will be higher.
解释：
C is correct.
考点：current method VS temporal method.
解析：如果美元是functional currency = reporting currency, 我们选择temporal method.
而且这个题说的是LC 是贬值的。这个条件很重要。
A选项：在temporal method下，COGS是用历史汇率转换的，在current method下, COGS是用较新的平均汇率转换，因为RMB在贬值，所以temporal method下的COGS比current method的要大，也就是说，Gross profit margin=（Sale - COGS）/Sales, temporal method的分子要更小，所以Gross profit margin也更小。
B选项：A/R turnover=Sales/ AR, 在2种方法下，sale都是用average rate, AR都是用CR，所以这个比率是一样的。
C选项，current ratio= (cash+AR+INV)/CL, 因为在temporal method下， 存货属于non-monetary, 所以要用历史汇率，所以INV的价值要更高，也就是分子更大导致比率更大。
这道题的汇率计价方式是RMB/USD还是USD/RMB？
