[求助]有兩句話不知道怎麼寫好，請大大指導，thx!!

1.organizations or groups不僅滿足了人類的基本需求，而且也發揮了特殊的功能。

2.加入organizations or groups，人們可以遇到和他們有相同困擾的人，而且可與他們分享自己的情感。

就是紅色的字不知道怎麼表達...請大大指教，謝謝，感激不盡～

It is difficult for me to translate the sentence that is out of context, but I try to understand in this way.

1.organizations or groups不僅滿足了人類的基本需求，而且也發揮了特殊的功能。

the organizations or groups not only satisfy the human beings' basic needs but also contribute to the operation of the society.

加入organizations or groups，人們可以遇到和他們有相同困擾的人，而且可與他們分享自己的情感。

people can share their feeling and experience with members.

Thank for guandream's help~

Since those are the sentences I met when I practiced an essay, they may look like out of context here.    Wish you never mind.

May I ask more questions? Do the words ,"exert" "utilize" "use", have the similar meaning? For example, we can exert(=use=utilize ?) the strength of  groups to solve all kinds of problems.

And "all kinds of" = "various" = "diverse" ?

I have been confused with those for a long time. Wish somebody kind to tell me the answers.

Appreciate your help.
