问题如下：
In order to reduce trade deficit in a country, a feasible way is
选项：
A.Increasing its capital account surplus.
B.Decreasing expenditures relative to income.
C.Decreasing domestic saving relative to domestic investment.
解释：
B is correct.
In a country, decreasing a capital account surplus will improve a country trade deficit, which means domestic savings increase relative to domestic investment. Domestic savings increase means decreasing expenditures relative to income. A large capital account surplus (an increase in net foreign borrowing) and a greater trade deficit is consistent with decreasing domestic saving relative to domestic investment.
考点：The Trade Balance
解释：在一个国家，减少资本账户盈余将改善该国的贸易赤字，这意味着国内储蓄相对于国内投资有所增加。所以A错误，B正确。
而国内储蓄的增加意味着支出相对于收入的减少。所以C错误。
巨额资本账户盈余(净外国借款的增加)和更大的贸易逆差，与国内储蓄相对于国内投资的减少是一致的。
a选项为啥错误，上一题才说了这个答案是正确的
