1.这两个句子在翻译上面有什么区别?
It is ten days since I arrived.
-----这是时间状语从句-----我到这里已经10天了
It was ten days ago when I arrived.
这是错句,应该把when换成that,变成强调句.
-------我是10天前到的.
2.都是对的 I suppose it wrong to tell lies.
----这是简单句
I suppose it is wrong to tell lies.这是宾语从句
3.这两个句子都是对的 I think it（形式宾语） impossible that he should ill-treat her（从that到最後是真正宾语）.
-------这是宾语从句
I think it is impossible that he should ill-treat her.这是宾语从句
