A. what do they call these animals

B. how they call these animals

C. what they call these animals

D. how do they call these animals

答案：

A. what do they call these animals

B. how they call these animals

(答案→)C. what they call these animals

D. how do they call these animals

解析：C 考查宾语从句的语序。宾语从句用陈述句语序，即“主语+谓语+宾语”，排除A、D；“他们叫这些动物什么”，what做the animals的宾语补足语。故选C。
