帮忙把这段话修改一下```谢啦

After reading this passage,and as a high school student,I,togetther my
friends volunteered on a campaign to discourage public smoking by
persuacling people in public places to extinguish their cigarettes
and put their cigarettes ends into our mental boxes."no smoking" is
just a slogan .we must put it into practice.have you built up a big
confidence about stopping smoking successfully?would you want to live
a healthier life in the future just try quit smoking whatever obstacles you meet,just tell yourself i can do it !and we return give them a memorial sticker bearing patterns and words spreading the spirit of the "no smoking".
