句子哪里错误(英语)

He asked when the next train would arrive.
从句中用陈述语序;
would后用动词原形.由于arrive是不及物动词,所以后面不加宾语,如果是arrive at,后面就要加某个地方(sp.)

正确的是
He asked when would the next train arrive?

因为一般Sb. ask (that)后面一般跟一个完整的句子。那么正确的语序应该是把would 提前。

补充：我们可以把从句的部分分离出来，when would the next train arrive? 这是一个完整的句子并且可以单独使用，相当于代替了句子的宾语部分，用一个句子充当宾语。而按正常的句法语序来说，助动词应该是放在when后面的。

He asked when the next train would arrive at?
arrive是不及物动词

应该是：He asked when would the next train arrive.

He asked when the next train would be arrive?
