如何翻译

that 强调句式引导语
when =as they bored from England to France
as 当...的时候

that 主语
when 引入宾语
as是 当...的时候 的意思

呵呵,水平有限,成分说不清楚,但希望对楼主有所帮助.
1.that's when 用法类似 that's why,that's how,that's what .
2.as 我的理解是当.时
翻译:那是工作者们用大型机器开始每半小时挖出1000吨泥的时候,就是当他们从英国到法国挖井(通道)的时候.

That表示强调句式.
when 是强调句式的宾语,同时也是要强调的内容.
as表示当的意思.
that [简明英汉词典]
[TAt]

when [简明英汉词典]
