How didan elite group, a few business giants, how did they end up dominating, controlling a number of important national industries in the last quarter of the 19th century?

end up doing到底是最后還是結(jié)束？？

結(jié)束和最后是兩個(gè)不一樣的意思，那種情況下是最后？

end up doing不是“結(jié)束做某事”，而是“以目前分詞表示的結(jié)果而告終”。

end up + 目前分詞：

You could end up running this company if you play your cards right.

你如果處置得當(dāng)，到頭來這個(gè)公司能歸你掌管。

If no one helps him he may end up being a beggar.

假如無(wú)人幫助他，他最后或許會(huì)成為一個(gè)乞丐。
