What can bring young people the most benefit?

Some young people are free in the evenings or have days off at school, whichfrom which of the following ways can bring them the mostthey benefit most?

Trying to accumulate/gain work experience by getting a part-time job or volunteering in a community.

As time goes by, technology offers most people equally have an opportunityies to gainaccess abundant resources from the iInternet to develop own abilityfor their self-development.

I feel like "As time goes by" doesn't really fit in here, I'd probably say "As technology advances, people are offered equal opportunities to access abundant online resources for their self-development."
I'm not sure though, maybe a native speaker can shed some light on this?

Nowadays, young people live in a competitive society, m. More and more parents have begiun to pay attention ton their children’s education —　not only academic works but extracurricular activities as well.

Among the three choices offered in the prompt, I side with trying to accumulate work experience by a part-time job or volunteering in a community brings young people the most benefithe first one. I think young people would benefit most from trying to accumulate work experience.

To begin with, accumulating work experience by getting/doing a part-time job is aoffers the best chance to observe/experience the real work lifeplace environment.

Only through a practical work experience, can young kids discover how iwhat does the workplace look like (/ what is the workplace like) and be prepared in advance.

WBy working at a restaurant, for instance, children are able to learn how to order, makedo dishes,place set tables and so on.

I'd avoid using "children" in this sentence since it usually refers to people that are really young, like below 16 or something. That's child labour right there, lol!
Also, I'm not sure what did you mean by "make dishes". Here I assumed you were talking about cleaning the dishes, which is "do dishes".

Through the working experience, they could certainly understand the whole process inhow real life works, not just imagination or even make surefrom their imagination. They could even find out if this is the job they want to do in the future.

SoTherefore, having prior working experiences previously have much morewill benefit to young people, t more. They will not waste their time to recognize what working area do they likeon deciding which area/field do they want to work in after they graduated.

Moreover, volunteering in a community is a priceless opportunity to learn interpersonal skills.

In present-Nowadays, people are gradually loseing their ability tof communicatinge with peopleothers face -to -face since they arely too relymuch on communication applications.

A case in point, being a volunteer in a hospital, young people have a chance to communicate with doctors, patients, and the others volunteers, meanwhile they are able to which cultivates their interpersonal skills.

In addition, these skills definitely help them learn how to express their perspectives/opinion politely and respect others’ different viewpoints.

I'd say "appropriately" rather than "politely" in this case?

Admittedly, some people might think that it would be more beneficial for young people to learn to play a sport or learn to play a musical instrument are more beneficial.

These either enhance their teamwork abilityskills or develop their all-round interests.

Playing in a basketball match, for example, players indeed need each other to cooperate with each other, build their well-team coordinatedion and gain a victory as a goal whichmake it a goal to win a victory. They all require a lot of practices to achieve.

However, having work experiences or volunteering in a community cannot only havgives young people a better picture of real work life but also allows them to learn interpersonal skills.

For me, if children want to survive in this severe world of the time, after all, they should be prepared.
