66、Neither a rising standard of living nor balanced trade, by itself, establishes a country's ability to compete in the international marketplace. Both are required simultaneously since standards of living can rise because of growing trade deficits and trade can be balanced by means of a decline in a country's standard of living. If the facts stated in the passage above are true. a proper test pf a country's ability to be competitive is its ability to_____ (A) balacnce its trade while its standard of living rises 我对于A作为答案没有异议，但是我觉得题目后半句的表达有问题。两个红色的can，我觉得应该都换成can't才对，否则的话，意思完全和前半句反过来了。我是不是疯了，觉得ETS出错题目？ |
