Your Teen Is Falling Asleep in Class

    Teens have a busy morning schedule as they need to wake up and get moving very early in order to catch a bus and get to school by the required time. This means teens need to get their rest the night before or they will be too tired to learn anything at school. ____

    When a teen falls asleep in class, two things happen: he/she misses what is being taught and he/she loses the respect of the teacher. He/She may also receive a consequence from the school, depending on the classroom discipline policy. ____

    To prevent your teen from being sleepy in class, try these three tips:

    *Set a time for “lights out” on school nights. This is never any later than 10 p.m. and preferably 9 p.m. ____ Soft music can be on and used to help calm your teen.

    *Help your teen develop a nighttime routine that involves activities that slow them down for the end of the day. ____ Turning off the computer and disconnecting from friends and the excitement of the day an hour before bedtime will also help your teen relax.

    * ____ This will reinforce (增强) what it feels like to be rested and capable of accomplishing what he/she wants.

A.What's worse, they may even fall asleep in class.

B.Set a good example and show him/her your love for learning.

C.Taking a bath and reading are two activities that work well.

D.Point out the positives after your teen has had a good night's rest.

E.All of these things affect your teen's academic success and can be avoided.

F.“Lights out” means the computer, television, lights and cell phone should be off.

G.While your teen keeps his/her goals in line with your expectations, he/she may have his/her own goals.

借给你的温暖

江文胜

    这天晚上,天下大雪,出奇地冷。养猪专业户王老汉蜷缩在家里的火盆前,他不敢出门。

    忽然,狗叫。王老汉极不情愿地打开屋门,一股刺骨的寒风迎面刮来,他打了一个激灵。王老汉哆哆嗦嗦地来到院子里,没见到任何人,可狗还在叫。

    院子左边的一排房屋,是猪圈。他逐一查看猪圈,仔细地数,总共60头猪连毛发都没少一根。猪没被盗,狗为啥叫呢?肯定有情况,不然,通人性的狗是不会无缘无故地瞎叫的。果然,王老汉在那排距自己的住房最远的饲料库发现了“敌情”:喂猪的苕片饲料少了一袋!

    王老汉立马来了精神,他赶紧回到屋里,拉上三十岁出头的儿子金华出来寻找。原来下了雪,现在雪停了,院子里从院门到饲料库、从饲料库到院门各有两行脚印,清晰可辨。金华说:“咱们跟着脚印去追那偷饲料的人!”王老汉说:“这是一个人的脚印,咱俩去追,可以对付,铁证如山,看他如何狡辩。”

    父子俩一前一后顺着脚印一口气追到了蜡子山矿区宿舍。脚印通到一间砖房的门前没了,别的砖房都熄了灯,只有这间房没有熄灯。

    真是胆大包天啊!做了贼还敢亮着灯?王老汉这样想。

    窗是玻璃窗,玻璃上结满了冰花。左下角的一块玻璃没了,糊上了报纸。王老汉用舌头舔湿了窗户纸,用手指轻轻一捅,报纸上便出现了一个小孔:一个黑黑的瘦瘦的中年汉子,坐在屋里的矮凳上,他的头上还冒着热气。啊!那袋装有红苕片的大编织袋赫然放在他的面前。床沿坐着一个双手笼在袖头里的老头,床头的被子下露出一个小脑袋,一个中年妇女站在这个黑汉子的对面。

    王老汉父子猫着腰蹲在窗户外,大气不敢出,倾听着屋里的动静。

    “粮,借来了。这就是,红苕片,100斤。你还愣着干啥?还不快去熬苕片汤!”汉子的声音。

    “妈,快熬,我饿坏了,我要吃苕片汤。”小孩的声音。

    “亚龙,这粮是咋借来的?”老人的声音。

    “爹,我事先写好了借条,借条压在袋子下。”汉子的声音。

    王老汉一愣,心想,我怎么没注意到那借条!真的有?

    “这不是偷吗?自打你从娘胎里出来,我是怎么教你的?做人要本分!还好,留下了借条,人要凭良心。但借粮容易还粮难哪!矿上不开工资,啥时候能还上?”老人的声音。

    “爹,这个我想过。车到山前必有路,活人不能让尿憋死,我还有一双手。到春天,矿上如果还不能开支,我就到农村去帮工。听说王老汉厚道,日子也过得殷实,不然我干嘛要借他的。我想去他那里,帮他干活,用工钱抵粮钱……”汉子的声音。

    “快走!”王老汉在心里喊。他拉起儿子往家里赶。进了院子,王老汉急奔饲料库,果然发现了那张借条:

    家里无米下锅。借一袋红苕干片。春天还。蜡子山矿区吴亚龙,此据。

    某某年某月某日

    上面还有一个用墨水作印泥盖的“吴亚龙”的私章。

    太阳从蜡子山上露出头来。吴亚龙推开屋门,见门口堆了一些东西:一袋大米、一袋面粉、一大块猪肉、几条鲜鱼和一袋冻豆腐……吴亚龙像见到了天外来物似的翻来覆去地找,竟找不出一张哪怕是手指宽的字条……
