by that way和in that way的区别

1.by that way只是口语中使用 = in that way“用那种方法/以那种方式”,但是在正规语法中是错误的.
倒是有以下两个个短语用by的：
1）by the way“顺便说说/顺便提起”或“在路上/在途中 ”
如：Oh,by the way,while you were away I had a message.
哦,顺便提一句,你不在的时候我收到了一条消息.
You will have a fine view of Moray Firth by the way.
在途中你将欣赏到马里湾的美丽景色.
2）by way of..."路经/途经”或“作为/当作”或“意在/为了”.
如：They are traveling to France by way of London.
他们经伦敦去法国.
We had some sandwiches by way of a meal.
我们吃了一些三明治,就算是一顿饭了.
He did it by way of helping me.
他这么做的目的在于帮助我.
2.in that way一般是两种意思：“用那种方法”或“在那方面”
如：You can solve the problem in that way.
你可以用那种方法解决这个问题.
These animals are different in that way.
这些动物在那方面相异.
