She thought that she should have taken Russian She thought t

应该是前一个,She thought that she should have taken Russian .
should have done 应该做而没有做
再问： 但在这里表示的是她实际上也做了，如果先表示在过去认为应该做某事，要用什么时态啊？ 其实也就是想问前面应经thought了，后边用一般还是过去？
再答： 用在should后面应该是动词原形，但是感觉这样造句怪怪的，如果是我的话会用，she had being thinking of taking Russian and she did so.
再问： 所以如果是我问的那个意思应该选第二个么？ 用should take？谢谢啦~~
再答： 是的，不用谢
