    Students these days often have a lot of worries. Sometimes they have problems with their schoolwork, and sometimes with their friends. What can they do about this? Some people think the worst thing is to do nothing. Laura Mills, a teenager from Washington, agrees.    "Problems and worries are normal in life," says Laura. "But I think talking to someone ____ a lot. If we don't talk to someone, we'll certainly feel worse "

    Laura once lost her purse, and worried for days. She was afraid to tell her parents about it. She even walked three miles to school each day because she didn't have any money. She just ____ thinking, "If I tell my parents, they'll be angry!" But in the end, she talked to her parents and they were really understanding. Her dad said he sometimes made careless mistakes himself. They got her a new purse and asked her ____ more careful. "I will always remember____ my problems in the future!" Laura says.

    Robert Hunt advises students about common problems. He feels the same way as Laura. "It is best not to avoid our problems. We should always try to solve them." He thinks that you can first find someone to talk to. This person doesn't need to be an expert (专家) like himself. Students often forget that their parents have ____ experience than them, and are always there to help them.

    In English, we say that sharing a problem is like cutting it in half. So you're halfway to solving a problem if you talk to someone about it!

写给母亲

贾平凹

    ①算一算，再有20天，我妈去世就三周年了。

    ②三年里，我一直有个奇怪的想法，就是觉得我妈没有死，而且还觉得我妈自己也不以为她就死了。我妈跟我在西安生活了14年，大病后医生认定她的各个器官已在衰竭，我才送她回棣花老家维持治疗。每日在老家挂上液体．她也清楚每一瓶液体完了，儿女们会换上另一瓶液体的，所以便放心地闭了眼躺着。到了第三天的晚上，她闭着的眼再没有睁开，但她肯定没有意识到从此再不醒来．因为她躺下时还让我妹把给她擦脸的毛巾洗一洗，梳子放在了枕边．系在裤带上的钥匙没有解，也没有交代任何后事啊。

    ③三年以前我每打喷嚏，总要说一句：这是谁想我呀？我妈爱说笑，就接茬说：谁想哩，妈想哩！这三年里，我的喷嚏尤其多，喷嚏一打，便想到我妈了，认定是我妈还在牵挂我哩。我更是觉得我妈还在，尤其我一个人静静地待在家里，这种感觉就十分强烈。我常在写作时，突然能听到我妈在叫我，叫得很真切，一听到叫声我便习惯性地朝右边扭过头去。从前我妈坐在右边那个房间的床头上，我一伏案写作，她就不再走动，也不出声，却要一眼一眼看着我，看得时间久了，她要叫我一声，然后说：世上的字你能写完吗，出去转转嘛。现在，每听到我妈叫我，我就放下笔走进那个房间，心想我妈从棣花来西安了？当然房间里什么也没有，我却要立上半天，自言自语我妈是来了又出门去街上给我买我爱吃的青辣子和萝卜了，或许，她在逗我，故意藏到挂在墙上的她那张照片里，我便给照片前的香炉里上香，要说上一句：我不累。

    ④整整三年了，我给别人写过十多篇文章，却始终没给我妈写过一个字，因为所有的母亲，儿女们都认为是伟大又善良，我不愿意重复这些词语。我妈是一位普通的妇女，缠过脚，没有文化，户籍还在乡下，但我妈对于我是那样的重要。已经很长时间了，虽然再不为她的病而提心吊胆了，可我出远门，再没有人哆哆唆唆地叮咛这叮咛那，我有了好吃的好喝的，也不知道该送给谁去。

    ⑤在西安的家里，我妈住过的那个房间，一切摆设还原模原样，我一次又一次难受着又跟自己说，我妈没有死，她是住回乡下老家了。今年的夏天太湿太热，每晚被湿热闹醒，恍惚里还想着该给我妈的房间换个新空调了，待清醒过来，又宽慰自己，我妈在乡下的新住处里，应该是清凉的吧。

    ⑥三周年的日子一天天临近，我准备着香烛花果，回一趟棣花了。但一丢坟上，现实告诉我我妈是死了，我在地上，她在地下，阴阳两隔，母子再也难以相见，顿时热泪肆流，长声哭泣。
