32.C.

　　33. A.

　　34. A. 本句话的先行词应该是films, 因此，关系代词that是负数概念，其谓语动词应用复述的被动语态have been shown。如果句中的one前面使用了定冠词the，则the one应该视为先行词。

　　35. A. “谈到某事物”应说talk about sth.。about是介词，其后要用which作宾语，不能用that。

　　36. A. with which是"介词+关系代词"结构,常用来引导定语从句。with有"用"的意思,介词之后只能用which,不能用that. with which在定语从句中作状语,即he is writing with a pen.

　　37. C. in front of which 即in front of a farmhouse. In front of which在从句中作状语.

　　38. D. with whom引导定语从句.with whom放在从句中即

　　为:my father works with the engineer.

　　39. D. whose引导定语从句,在从句中作主语family的定语.

　　40. A. that引导定语从句,因为先行词是all,所以只能选用that引导.
