Question

She entered the station twnty minutes before the train was due,since her parents had impressed

She entered the station twnty minutes before the train was due,since her parents had impressed upon her that it would be unforgivable to miss it and cause the friends with whom she was going to stay to make two journeys to meet her.
请帮我详细的分析一下这段句子，有几处看不懂，since her parents had impressed upon her that it would be unforgivable to miss it and cause the friends with whom这里的 impressed upon her是固定搭配吗， 还有and cause the friends with whom这里的cause是动词吗？ 它的主语是前面的it吗？为什么cause还是动词原形不变呢？
还有一个问题 the friends with whom she was going to stay to make two journeys to meet her，这里的with whom为什么用with whom又是指谁，she was going to stay to make two journeys to meet her这里也没看懂
问题有点多 请见谅

Answer 1

为你解答如下：

1. impress sth. upon sb. 意为“把某事留在某人的印象中”

   此句中的sth.是that从句，因为太长了，所以移到了sb.后面，变成impressed upon her that...。

   
   

2. cause是及物动词，用法之一是cause sb. to do sth.

   此句中cause the friends (with whom she was going to stay) to make ...就体现了这种用法。

   cause和miss是并列关系，承前省略了to，两者同作that从句的真正主语，形式主语是第一个 it。

   
   

3. whom指the friends，with是和stay搭配使用的，即stay with sb.（和某人呆着一起）

   with whom she was going to stay是定语从句，修饰the friends
   

句子意思：

她在火车发车前20分钟就进站了，因为她的父母已经嘱咐她，（假如）错过火车就会使她将要去拜访的朋友多跑两趟来接她，这将是无法饶恕的。

【不好意思，刚才看错了一点。】

Answer 2

She entered the station twnty minutes before the train was due,since her parents had impressed upon her that it would be unforgivable to miss it and cause the friends with whom she was going to stay to make two journeys to meet her.

impressed upon sb是固定搭配，指使某人意识到（重要性或严重性），
and cause the friends with whom这里的cause是动词, 它的主语是前面的it吗？cause是动词原形不变,因为省略一个和to miss并列的to
the friends with whom she was going to stay to make two journeys to meet her，这里的with whom为什么用with whom指谁friends，
she was going to stay to make two journeys to meet her,如果她未能赶上火车去看她的朋友们，那么她的朋友们就要坐车来见她，这样她的朋友们不是要跑两趟吗。

希望能帮助你，满意请点“采纳”

追问

我还是有点不明白，是不是这样这样理解cause the friends to make two journeys to meet her，
而这with whom是对应she was going to stay？如果我理解没错那这句话是不是也可以改成把with放到stay后面

追答

是的

我个人看不是，cause是动词，整个句子的时态是过去时，with whom指代前面的friends,还有你句子的成分划错了
