I discovered when I was checking her system.  When I use "It was...", does not imply that she informed me the fact?

It was noted that her current system does not have MS Office. 

The phrase, "It is recommended that ... "  - I thought I need to use participate (without s) even if she or he is used??

It is recommended that she actively participate in the appropriate training, including orientation and mobility skills, so that she can remain involved in volunteer work in her community and thereby expand her employment opportunities.
