in addition to 与 apart from的区别？

in addition to除...之外(还)
In addition to a diet, she pursues various exercises on TV.
节食以外她还随电视做体操。

apart from除了...之外;

Apart from English, we study Russian and Spanish.
除了英语以外, 我们还学俄语及西班牙语。
上面两个句子中词组短语意思相同,可以互换
但是apart from还有"脱离"的意思,如:She keeps herself apart from other people.她与别人保持距离.这里就不可换

in addition to
除...之外
in addition to French,he has to study Japanese.

apart from=except for
除...之外;
I've finished apart from the last question.

Apart from their house in London,they also have a villa in Spain.

本人觉得apart from可以等代in addition to
但apart from有更多的解释,就如上例(apart from everything else,别的不用说)
