Question

【題目】He is so stubborn that once he makes up his mind, nothing can change it, _______, it's no use arguing with him.
A.therefore
B.however
C.besides
D.so

Answer 1

【答案】A
【解析】考查連詞辨析。therefore意為“因此”；however意為“然而”；besides意為“除了……還有”；so意為“所以”，句意：他是如此固執(zhí),一旦他決定,沒有什么可以改變它,因此,與他爭論是沒有用的。根據(jù)句意可知選項A正確，故選A。
