英语问题－状语从句
体育馆正在建造时,事故发生了．用状语从句怎么翻译这句．
答
一般形式（两个句子）：
The gym is building. An accident was happened.
复合句（时间状语从句）：
The gym was building when an accident happened.
解析：因为“体育馆是正在建造”，也就是正在进行这个动作，所以用进行时；而“事故发生了”，也就是表示完成了，所以用完成时。
答
The gymnasium was being built when an accident happened.这是并列句，when=and at that time.
如果非用状语从句，可译为An accident happened while the gymnasium was being built.
答
When the stadium was beening built ,an accident happened
时间状语从句
答
The gymnasium was being built when an accident happened.
这个句型用来表示：正在做。。。时，（突然）发生了。。。
