Usually, the Valentine’s Day has no connection with the traditional Chinese

festival, but this year, the Lantern festival falls on the same day with the

lovers’ day. Well, some young will face a dilemma，especially for those who

doesn’t get married. Should they spend the day with their families or their hot

lovers? That’s a question. I’ve got a key that can solve this problem.

Family comes first of course. You should wake up a little earlier in the

morning, and help your mother in the kitchen. On the Lantern Festival, making

rice balls and dumplings are the traditional activities. Having a reunion dinner

with the whole family is also very important, so you need to show up and stay

with your family for the whole morning. Spend some time with your family. Keep

them company and make them happy. In the afternoon, there are maybe not so busy,

you can plan for the Valentine’s Day with your girlfriend or boyfriend, you can

have some snacks in 4p.m, and tell your parents you will hang out with your

friends at night and not having supper at home tonight. They would be

understood. Then you can take your girlfriend or boyfriend to a nice restaurant

and see the latest movie after dinner. Do not forget to present the gift you

prepare for your lover. Make your lover happy, too.

I think everybody should find a balance between family love and lover’s

love. If I can only choose one, I will choose family love over the other.

Because I know my family never leaves me and my parents are aging. How many days

can I still be with them? So I really appreciate the days that I can still be

with them. I know you will do the same just like me.

译文：

记忆穿过时间的隧道，随着时间的蔓延，一幕一幕美好的回忆始终在脑海中荡漾。毕业那天，回头看看那曾经的校园，聆听那动听的歌声，回顾那甜美的笑脸，在操场上寻找奔跑的脚印，在走廊聆听高声唱过的歌，在花丛中捕捉蝴蝶的身影，在水池边期许鱼儿的踪迹……

丝丝春雨唤醒了沉睡着的学校。柳条在空中舞蹈；桃花冲我们微笑；小草向我们弯弯腰……和煦的阳光照在绿油油的操场上，美丽的蝴蝶在花丛上空盘旋，蜜蜂们也在忙着采蜜，校园里处处洋溢的同学们的欢笑声。

声声“知了，知了”的蝉叫，炎热的夏天到了。太阳吧操场晒得直冒烟，可同学们的心情并没有被打扰。凉亭下，走廊上，小池边，花园里，女孩子们轻轻摇动着手中的折扇，徐徐微风将他们头上的刘海吹了起来，男孩子们则调皮的爬到树上去捉蝉，还有人在池边戏水呢！

瑟瑟秋风，让秋天不知不觉的进入校园。教学楼下的两排枫树矗立着，像英勇的禁卫军，动也不动的守护着我们。树上的枫叶被风一吹，纷纷落在了我们的头顶上。心灵手巧的女生们将它们做成一片一片的书签。花园里的菊花都开了，个个争奇斗艳，像婀娜多姿的少女。可男生们一点也不懂得爱惜，将花儿都摘了，在楼上来了个“天女散花”！

刺骨的寒风带来了严冬。校园里最美的就要属雪景中的梅花了。雪花妹妹从空中飘落下来，像仙女在空中舞蹈，衬托了梅花的红。在沙坑旁有一排冬青与梧桐，顽皮的同学会拾起雪球，朝树上扔去。

毕业那天，我们回顾，我们回忆，好美，好美……

亲爱的同学们：

曾经从一本书上看到一句话，这句话令我记忆犹新：“只要心还在跳动，血还是热的，就要抬起头来做人，做一个真正的人，一个讲究诚信的人”。

记得有一次，我到小店买东西，由于店员的疏忽，多找了我6元钱，我不知所措，觉得应该还回去，可又想自己留着，心里很矛盾。情急之下，我想到了一个“好”主意。我只把两块钱还了回去，剩下的钱悄悄揣在兜里，店员还直夸我很诚实。

回去的路上，我回忆着自导自演的这一出，心里十分不安，觉得自己太不诚实了。小鸟依然叫着，但没有之前那样动听，柳枝依旧向我点头，但没之前那样亲切。我犹豫了片刻，还是下定了决心：“一定要做一个讲诚信的人”。我坚定地把剩下的钱还了回去，看到店主眼中流露出的欣喜和赞赏，我的心情舒畅多了。

这的确不是什么惊人的大事，只是一件平凡的小事。但把平凡的小事做好，即为不平凡，把简单的事做对，就是不简单。这件平凡简单的小事时常提醒我要诚实守信，希望大家一起发扬传统美德，做一个诚实守信的人。

英语字母教学作为英语学习的基础，是小学英语教学中重要一环，这一阶段的教学，教师应给予足够的重视，通过各种教学组织形式使这一阶段的学习得以很好的落实。学好26个字母对以后单词的学习起着至关重要的作用。因此，在学习字母阶段，我们要利用一切可利用的资源，创设情境，让学生和字母交朋友、做游戏。

一、字母读音教学

1. 注重示范发音的正确性

字母发音直接影响着学生单词的发音，而且学生错误的发音一旦形成就很难再纠正。因此教师在教学字母之前一定要多听录音，纠正好自己的发音。在课堂教学中教师要让学生听磁带跟读，观察他们的口形，并鼓励模仿得好的学生示范领读，帮助其他同学纠正发音。

2. 把握学生的发音难点

受各地方方言的影响，学生对字母的发音往往会出错。比如：南方人容易把A读成/e/。因此，教师要把握好学生方言发音难点，预先采取各种教学方法防止错误发音的出现。

3. 强化个别字母教学

尽管许多学生对字母有了一定程度的掌握，但大多数学生都没有进行过系统的字母学习，中间难免存在着许多似是而非的现象。例如学生对GgJj两个字母的读音容易混淆，对Uu和Ii这两个字母的发音不到位。教师在教学中应针对这种情况加强这几个字母的训练。

4. 注重读音归类教学

把字母按读音进行分类是字母读音教学的一个重要任务，也是学生觉得有一定难度的一项内容。为了使学生能更好得掌握，教师可采用分家游戏的方法，按家族将26个字母进行分类记忆。首先将字母划分为七个家族，再对号入座，最终编成一首音素家族chant 帮助学生记忆：

A、H、J、K 是A 家族，A，A是族长。

E的家族有八位，BCDE，GPTV，E，E是族长。

/e/ 的家族没有族长，它的成员有七位，FLMN，SX 和Z。

U 的家族有三位，UQW，U，U是族长。

I 的家族有两位，IY，I，I是族长。(手势指着自己)

R 和O单独住，它们自己是族长。

5. 注重语音暗线的铺垫

在三年级下册学生用书中，字母读音和字母例词的安排是一条语音暗线，教师教学时要努力让学生掌握字母的正确读音，并初步感知字母在例词中的读音，为以后学习语音奠定基础。比如讲到字母Ee时，例词是egg，elepghant，教师可突出字母E的发音。英语有48个国际音标，如果学生能在学习 26个字母的同时掌握与此相关的26个音素，将会为以后的语音学习打好基础。

二、字母书写教学

字母的书写过程要一步步进行：先观察性状，再观察笔顺、占格情况，然后书空，使用活动手册进行描红，最后达到仿写。

1. 字母认读的教学

字母的书写首先要求学生能正确区分一些形近的字母。有些字母可以通过猜谜的方法让学生记住它们的形状特点。例如：弯弯的月牙(C)、一条小蛇 (S)、三叉路口(T)、1加3(B)、一座宝塔(A)、胜利的象征(V)、大号鱼钩(J)、一张弓(D)、一扇小门(n)、一棵小苗(r)、一把椅子 (h)。这些谜语既能让学生记住字母的形，又能激发学生的学习兴趣。同时，还可以让学生自编谜语学习字母，充分发挥学生的想象能力。另外，还可以将字母的一部份遮住，让学生根据漏出来部分来猜字母。

2. 字母书写的教学

字母的书写是小学生的一个薄弱环节。小学的英语书写一定要求学生做到严格遵照书写规范，教师绝对不能马虎。因为英语字母有印刷体和书写体之分，所以容易使学生在书写时发生混淆，教师在教学时应多在这方面进行强调。

(1)笔顺教学

教师要充分利用多媒体设施让学生仔细观察字母的笔画和笔顺。正确的笔顺在活动手册的描红练习中有正确的示范。但有时学生会受到汉语拼音笔顺的影响，错误书写字母，因此教师要对容易出错的笔顺进行比较细致的指导。如i和j都是后加点，t先写钩，H先两竖等。建议教师不妨采用汉语拼音的教法，使用一些形象的比喻，帮助学生理解记忆书写规则，防止笔画出错。比如：H是一双筷子拴根线，j是海豹顶皮球，i是小海狮头上顶个球，t是伞把带开关等。

(2)格式教学

字母的占格同样是字母书写教学中的一个教学难点，尤其是当字母的大小写混在一起的时候，学生很容易混淆。这样，教师要先清楚示范，提醒学生注意并总结字母占格的规律。同时，教师还可以借助儿歌帮助学生掌握字母的占格规律。如：英语书写，四线三格，大写字母一二格，上不顶线是原则;小写字母认准格，上面有 ‘辫’一二格，下面有‘尾’二三格，无‘辫’无‘尾’中间格;i，t中上一格半。在学生掌握了字母的占格规律后，还要通过活动手册上的描红来加强练习。这里要注意的是，到一定阶段的时候，教师要让学生能在没有四线格的一条线上，甚至是没有任何线的白纸上也能正确地表示出字母的书写格式。

三、操练

字母操练我们还可以采用游戏的形式。

1. What’s missing?游戏

学了几个字母以后，把字母卡片放在一起让学生认读，然后抽去其中的一张，让学生寻找：What’s missing?此时，学生注意力高度集中，急于表现自己，识记的效果就会很好。

2. 左邻右舍游戏

学生准备好已经学过的字母卡片，教师出示一个字母，让学生找出它的左邻右舍，请找到的几个学生快速把字母拿到讲台上站在相应的位置上，其余的学生一起认读这几个字母。

3. Make letters游戏

让学生用肢体动作表示不同的字母，或让学生用火柴棒拼出不同字母的形状。
