Question

when a small boy and his father were walking in the country,it suddenly began to rain hard.

1. 这句话对吗？
2. 这句话翻译成什么？
3. 这句话是不是由when引导的时间状语从句？
4. 哪句是从句，哪句是主句？
5. 在过去进行时中，由when引导的时间状语从句是一般过去时，主句是过去进行时，而这句怎么回事

Answer 1

1.不对。
2.当一个小男孩和他爸爸走在乡下时，突然开始下起了大雨。
3.是的，由when或者while引导的句子都是时间状语从句。
4.从句是A small boy and his father were walking in the country，主句是it suddenly began to rain hard.
5.这句就是when放错了位置。如果用when，应该是A small boy and his father were walking in the country, when it suddenly began to rain hard. 如果用while，应该是While a small boy and his father were walking in the country,it suddenly began to rain hard.

Answer 2

1. 对吧
2. 当小男孩和他父亲在乡间散步的时候，突然开始下起很大的雨。
3. 是
4. 从句是when a small boy and his father were walking in the country，主句是it suddenly began to rain hard。
5. 这个从句时过去进行时，主句是过去式。

Answer 3

不对，两个独立的句子之间应该有连词。应该是When a small boy and his father walking in the country,it suddenly began to rain hard
翻译：当一个小男孩和一、他父亲在村外走的时候，雨突然下大了
是
第一句是时间状语从句，第二局是主句
这句话本就有问题
