iceberg.

A.a; an

B.a; the

C.the; the

D./; an

解析：略
本题选A。
{02}—Shall we go out for__________walk?
—Sorry．This is not the right____________to invite me．I am too tired to walk．

A.a；moment

B.the；situation

C.a：place

D.／：chance

解析：考查冠词及词义辨析。短语：go out for a walk 出去散步，moment 时刻，situation形势，place 地方，chance 机会，根据答语中I am too tired to walk我太累了不能去散步。可推断出这个时候对说话人不合适。所以选A。
本题选A。
