    I am Jay from Yangjiang Sunshine Middle School. Recently, we carried out a survey on whom we prefer to share worries with. We got different answers.
    According to the survey, about 71% of the students would like to share their worries with their classmates and friends. It is mainly because they believe that if people are at the same age, they are easy to communicate and understand each other better.
    About 22% of the students said they would like to share worries with their teachers and parents. They think adults are rich in experience, and that they can solve their problems easily. The rest(其余的) prefer to keep worries to themselves. As for them, it's a struggle to get along well with others, some of them said they didn't want to trust anyone.
    In my opinion, I will share worries with my best friends because they're always kind and understanding. However, if I meet with some serious problems, I'll be likely to ask my parents and teachers for help, who, I believe, have more experience to give me valuable advice.

阅读《陈涉世家》一文的节选文字，回答后面小题。
       陈胜者，阳城人也，字涉。吴广者，阳夏人也，字叔。陈涉少时，尝与人佣耕，辍耕之垄上，怅恨久之，曰：“苟富贵，无相忘。”佣者笑而应曰：“若为佣耕，何富贵也？”陈涉太息曰：“嗟乎！燕雀安知鸿鹄之志哉！”
       二世元年七月，发闾左谪（需改为走之旁）戍渔阳，九百人屯大泽乡。陈胜、吴广皆次当行，为屯长。会天大雨，道不通，度已失期。失期，法皆斩。陈胜、吴广乃谋曰：“今亡亦死，举大计亦死；等死，死国可乎？”陈胜曰：“天下苦秦久矣。吾闻二世少子也，不当立，当立者乃公子扶苏。扶苏以数谏故，上使外将兵。今或闻无罪，二世杀之。百姓多闻其贤，未知其死也。项燕为楚将，数有功，爱士卒，楚人怜之。或以为死，或以为亡。今诚以吾众诈自称公子扶苏、项燕，为天下唱，宜多应者。”吴广以为然。乃行卜。卜者知其指意，曰：“足下事皆成，有功。然足下卜之鬼乎？”陈胜、吴广喜，念鬼，曰：“此教我先威众耳。”乃丹书帛曰“陈胜王”，置人所罾鱼腹中。卒买鱼烹食，得鱼腹中书，固以怪之矣。又间令吴广之次所旁丛祠中，夜篝火，狐鸣呼曰：“大楚兴，陈胜王”。卒皆夜惊恐。旦日，卒中往往语，皆指目陈胜。
