質問: このwithはどんな意味を表してるんですか?
回答: 2つの文に分けると 1He went to buy some tools 2to fix the table with some tools *12でsome toolsが共通なので先行詞となり、関係代名詞whichを使って 1つの文にすると He went to buy some tools which to fix the table with. withをwhichの前に持ってくると He went to buy some tools with which to fix the table. なのでwith which=2のwith some tables です。
