Have you seen Jack recently? I wonder with his classmates.

A. how is he getting along

B. that he is getting along well

C. what he is getting along

D. if he is getting along well

答案：

A. how is he getting along

B. that he is getting along well

C. what he is getting along

(答案→)D. if he is getting along well

解析：考察宾语从句。在英语中，所有的名词性从句都要使用陈述语序的形式。句意：你最近看见Jack了吗？我想知道他和他的同学相处地怎么样？根据句意说明使用if引导这个宾语从句。固定搭配get on/along with…与…相处。故D正确。
