mike老師，

這題只有您能解了！

可否請教您，這一句是我從某雜誌看到的，雜誌上寫were，但我總覺得應該是where才對吧?? 請問是were 或where呢??

1. Located at the north end of the Willamette Valley "were" two rivers meet, Portland is surrounded by majestic forests and volcanoes.

2. Located at the north end of the Willamette Valley "where" two rivers meet, Portland is surrounded by majestic forests and volcanoes.
