This is the park where we held a birthday party. = in which2. She wont forget the days (which/ that) she spent on the island. She wont forget the day when they stayed together. = on which分析例题：1) This is the factory _B_ I visited last year. 2) This is the factory _A_ I worked last year. 3) This is the factory B produces all kinds of TV sets. A. where B. which C. whom D. whose 以上三个句子只有细微的差别，但答案却不同：做这种题时，要通过还原先行词,看先行词在定语从句中所充当的成分；1）还原为: I visited the factory.是动宾关系，因此选 which2）还原为: I worked in the factory，factory应在定语从句中作地点状语，因此选 where3）还原为: the factory produces all kinds 是作定语从句中的主语，不作地点状语，因此选which4）Can you lend me the novel _ D_ the other day?A. that you talkedB. you talked about itC. which you talked withD. you talked about还原后为：You talked about the novel the other day.故it要删掉，先行词在句中作宾语，关系代词可以用which/that或者不填。例题（一）：1.The place B interests the children most is the childrens palace.
