- ----- It’s too strange that these people should laugh when their relatives die.
----- That is the local custom ______ the seventeenth century.| A．dates back to | B．dated back to |
| C．dating back to | D．had dated back to |
- 答案：C
- 试题分析：考查非谓语动词。date back to追溯到---，句意：那是追溯到十七世纪的当地风俗。句子有谓语动词，没有引导词，所以此处不是从句是非谓语动词，date back to无被动形式，故用现在分词作后置定语，因此选C。
考点：考查非谓语动词。
