    I was taking a train to London's Victoria Station．I had noticed that the carriage was noise and filled with people．Before long，a train inspector comes to check out tickets．A passenger realized he couldn't find his ticket but became quite upset．Then everyone in the carriage began searching the ticket，that was eventually found under a seat several rows from its owner．The person who found a ticket smiled with pleasure at his success．No one in the carriage had previous spoken to or even noticed the ticket-owner before．Yet，they had so quickly offered the strangers their help．If we could show concern to others on need，the world would be a better place to live in．

详
1．去掉had；考查动词的时态．本文叙述的是过去发生的一件事情，故用一般过去时．句意：我注意到车厢里很吵闹都是人．
2．noise改为noisy；考查形容词，本句中应该使用形容词noisy和系动词was构成系表结构，修饰车里当时的情况．同时noisy与后面的形容词短语filled with…构成并列关系．
3．comes改为came；考查动词的时态，因为本文讲述的是过去发生的事情，所以使用一般过去时的时态．
4．but改为and；考查连词，句意：一位乘客找不到自己的票，很难受．上下文之间是顺接关系，所以使用and．
5．searching后面加for；考查固定搭配，根据句意可知每个人都帮助他找票．固定搭配search for sth意为"寻找…"．
6．that改为which；考查关系代词，这是一个非限制性定语从句，先行词为the ticket，故用关系代词在从句中作主语．
7．a改为the；考查定冠词，定冠词the特指上文提及的同一事物，本文中特指前面提及的那张票．
8．previoes改为previously；考查副词，本句中应该使用副词previously作状语，修饰谓语动词．
9．strangers改为stranger；考查名词，句意：他们如此迅速地给与陌生人他们的帮助．本句中的陌生人就是指那张票的主人，是一个单数形式．
10．on改为in；考查介词． in need是固定搭配，意为"需要"．句意：如果我们向那些需要帮助的人表示关心，这个世界就会变得更美好．
