Q: how can I set photos to show me images by dates?

No - that is not currently an option - tell Apple what you need - https://www.apple.com/feedback/photos.html

and Apple has announced more sorting options will be available in El Captain this fall - http://www.apple.com/osx/elcapitan-preview/?cid=wwa-us-kwg-mac-com

.I don't like that,because I have to scroll my trackpad for long to scroll the album to the end to watch the newest photo which I shot,

I don't like it either, but I have set the System Preferences > General  to always show the scrollbars. This way I can click at the end of the scroll bar to jump to the bottom of the album and don't need to scroll:

and I found that the images in the album list as date added automatically

That's not true.  In albums images are displayed by Date Taken ➙ Ascending, not date added.  They can also be manually sorted in an album.
