问题如下：
A country with a trade deficit will most likely:
选项：
A.have an offsetting capital account surplus.
B.save enough to fund its investment spending.
C.buy assets from foreigners to fund the imbalance.
解释：
A is correct.
A trade deficit must be exactly matched by an offsetting capital account surplus to fund the deficit. A capital account surplus reflects borrowing from foreigners (an increase in domestic liabilities) and/or selling assets to foreigners (a decrease in domestic assets). A capital account surplus is often referred to as a "capital inflow" because the net effect is foreign investment in the domestic economy.
考点：The Trade Balance
解析：当一个国家出现贸易逆差时，就表明该国进口了更多的商品，出口了较少的商品。
资本账户和经常性账户具有此消彼长的关系。经常性账户出现赤字，那么资本账户就会出现盈余，所以A选项正确。
X-M=S-I+(T-G)
根据题意，X-M减少可以产生，S-I减少。这表明国内储蓄的钱不够，需要国外资金支援建设，所以B选项错误。
C选项也说反了，应该是外国人买国内资产以维持平衡，而不是国人买外国资产维持平衡。
资本账户可否理解为投资 I ？
