all along
1． for the whole length of一路；沿途
We saw green hills and forests all along the way．沿途所见，皆是青青的小山和森林。
2．all the time；from the beginning一直；自始至终
The manager said he suspected the man of stealing the paper all along．经理说他一直都怀疑是那个人偷了文件。
You've been nice to me all along，and I appreciate it very much．您一贯对我好，我非常感激。
