问题补充：

—What are you anxious about?

—.

A. How can we succeed

B. Whether we can succeed

C. When can we succeed

D. That we can succeed

答案：

A. How can we succeed

(答案→)B. Whether we can succeed

C. When can we succeed

D. That we can succeed

解析：这是一个省略句。完整的是:I am anxious about whether we can succeed, about后面是它的宾语，宾语从句的语序应是陈述语序，故排除AC，that在宾语从句中只起连接的作用，没有意义，故排除D，所以选B。
