The shelters _____the farmers_______the spiders enable them to survive cold winters.
为什么不用with what....provide而用which....supply to

shelters是其后定语从句的先行词,在从句做宾语成分,而关系代词which正是替代的shelters。
只有当从句中缺成分的时候才用what,而此句中不缺成分,所以不用what。

把这句话拆开来看,即可以拆成:
1、the farmers provide the spiders with the shelters.(provide with 也可换成supply to)
2、the shelters enable them (the spiders)to survive cold winters.
