The Supreme Court's concern with legitimacy is not for the sake of the court but the nation to which it is responsible.
(A)but the nation to which it is responsible
(B)but for the sake of the nation to which it is responsible
(C)so much as the nation it is responsible
(D)as the nation it is responsible
(E)but the nation
我也举的应该选B，B最平行。但是不是有be responsible for sth 的固定搭配吗？B中怎么出来be responsible to sth ？？？谢谢各位先。 |
