两个英语句子分析
1.Blamed for the breakdown of the school computer network,shi was xin low spirits.
为什么用Blamed（过去分词）?
状语是哪部份?过去分词做状语怎么理解,请举例.
2.When you get the paper back,pay special attention to what had been marked.
为什么用"had been marked"这个时态,而不是现在完成时.

Answer 1

1 Blamed for the breakdown of the school computer network
这是一个过去分词短语做原因状语
2 我觉得应该用现在完成时态
