They'er helping us build communities around the things we care about and (to) stay close to the people who are important to us,no matter where they are.请问括号中的to怎么理解?

第一句中的on是有关、对于、就...而言的意思,progress on ...problem：有关...问题的推进.全句翻译如下：
我仍然很大程度上是个乐天派,我相信即使世界上最困难的问题也是有可能逐步推进（解决）的.
第二句,stay close 和 build communities 是help us后面不定式的两个并列成份,help us (to) build...and (to) stay close.help后面的不定式可以省略to,即 help us to do = help us do.
努力一把,加加油,你一定能过四级.
