正确：I did it just because i saw other people were doing it.
两个句子都一样请问为什么一定要加上are 或者were 呢？I did it just because I saw other people are doing it.I did it just because i saw other people were doing it.这两个句子的时态有什么不同？为什么都可以？这句 I did it just because I saw other people are doing it.是错的因为are是现在的 were是过去的既然前面用was（过去）后面就得用一样的（过去）例子1: i am doing it because Sam is doing it too.例子2: i was doing that because Sam was doing that too.I did it just because I saw other people doing it.I did it just because i saw other people were doing it.以上这两句是一样意思 差别在你想不想加多一个词两句都是：我做了是因为我看过别人做过。
