Brown said he was by no means annoyed; he was glad to be able to make himself clearly understood.

A. all in all

B. for one thing

C. on the contrary

D. by the way

答案：

A. all in all

B. for one thing

C. on the contrary

D. by the way

解析：根据句意：布朗说他一点儿都不恼火。相反（on the contrary）他很高兴能够被透彻理解。All in all总而言之；for one thing其一；by the way顺便讲一下，均不符合语境，故排除。解题的关键是对词组by no means=never（决不）的理解。
