2. He had gone through six carriages when he found he could go no further .

〖明晰〗had + done … when / before sb + 过去式“刚……就；一当……便”。
We had stayed in the hotel for nearly an hour when / before word came that she had an accident .
另外，注意：had + done … when / before … 的倒装结构是：Hardly had …… 。如：
Hardly had she seen the snake when she gave out a cry of fear .
3. She found herself at the front of the train .
〖明晰〗find的复合结构有：find + 宾语　＋　介词短语（形容词、现在分词、过去分词、副词、不带to的不定式）。如：
I found the story moving .　（形容词）
I found the snake moving from side to side . (现在分词)
