今天是个风和日丽的好天，我和同学贺松去了北京动物园。动物们是那么可爱，大家都非常喜欢它们。一只熊挥动着胳膊向人们要吃的，一个游客就投进去了什么东西。我想都没想就走过去说：不要那样做。你的做法对它们没好处。如果真的喜欢它们，就应该爱护它们。他的脸红了，并且回答说他不会再那么做了。

为了进一步落实市局《校园食品从业人员培训会议》精神及《关于开展学校食品安全知识宣传月及食堂开放周活动的通知》要求，象山中学于五月份第二周举行了校园食品安全宣传及食堂卫生安全检查活动。

本次活动学校高度重视，专门召开办公会研究并进行了详细安排。由学校后勤处具体负责，教务处、政教处、电教中心共同参与。

活动开始，学校首先利用电子宣传牌、版面、课堂，向学生讲授相关食品安全知识、预防食物中毒和急性肠道传染病等卫生防病知识，以此来增强师生的卫生防病意识和自我保护能力。其次，学校进一步强化了膳食委员会的责任意识，同时继续推行领导陪餐制度，每天都安排相关领导在三餐时在餐厅与学生同餐，及时了解饭菜价格及质量。再者，学校在餐厅设立了咨询台，向家长和学生发放《致广大学生及家长的一封信》进行科普知识宣传，并安排专人进行咨询讲解。最后，学校还召开座谈会，认真听取了膳食委员会、学生和相关人士的意见和建议，并积极行动，进行整改，确保了学校食堂食品安全。

在我们学校的一角，长着一棵高大挺拔的黄桷树。这棵黄桷树大概有两个人那么高，粗得要好几个人才围得过来呢！树皮是泥巴色的，上面那些斑纹就像老人脸上的皱纹一般。不难看出，黄桷树无疑是经过了时间的考验。黄桷树的分枝特别多，越分越细，分布得也十分均匀。

黄桷树如一个春天的使者一般告诉我们春天的来临，当第一片叶子诞生时，我们便知道，春天来了。沐浴着和煦的阳光，一片片黄桷树叶纷纷降临于世。一片片嫩绿的树叶，无不透露出春的活力，看着这眼前的一片新绿，我仿佛嗅到了春天的气息。春风吹来，黄桷树与小鸟们跳起了欢快活泼的华尔兹，没有音乐的伴奏，但黄桷树却把音乐表现地淋漓尽致。这与生俱来的本领，更给春天增添了一分生机。

春天的脚步渐渐远去，黄桷树上的叶子从翠绿变为了墨绿色的了。火辣辣的太阳下，黄桷树依然挺拔而苍翠，我仿佛觉得它的身上散发着一股阳刚之气，如二十几岁的男儿一样充满了青春的活力。

不知不觉，秋天已到来了。黄桷树上的叶子开始泛黄了，一片片叶子随着秋风飘落了下来。与此同时，我惊奇地发现，黄桷树上居然长满了一个个圆滚滚的果子，我猜想，那是一种收获吧。

冬天里，黄桷树的叶子落光了，只剩下了光秃秃的树枝，显得有些孤寂。但我始终看不出它的苍老，它就像一个强者，随时准备迎接新的挑战，新的生活。

一年又一年，黄桷树经历着一次又一次这样的轮回，而每一个季节的它，都独具魅力。

人生可能也是一棵黄桷树吧。只有在春天播下了希望的种子，秋天才有果实！

Students need more outdoor activities学生们需要课外活动

Students need enough sports and activities to do physical exercises and relax, but in some schools they are not given enough time to do outside activities. Its harmful for students growth. Teachers ask students to spend most of their time on studies. But when they feel tired and bored, students cant concentrate on studies. They are in bad health.

Its necessary to give students enough time to do outside activities. After good relaxation and rest, studens will work harder.

Pay attention to students health and growth.

学生们需要足够的运动和活动来锻炼和放松，但是一些学校没有给予学生足够的时间从事课外活动，这对学生成长是有害的。老师为了让学生得高分，要求他们把大部分的时间放在功课上。但是当学生疲惫厌烦时，就不能集中精力学习。他们的身体也不好。

给予学生足够的时间从事课外活动是很必要的。休息好和放松后，学生会更加努力学习。

请关注学生的健康和成长。

[ 学生们需要课外活动英语作文

上班经过小树林，看见那些小树在寒风中摇曳着，心里很受触动。他们不惧刺冷的阵阵烈风，依然健康地成长着。左右摇摆宣示着它们不怕任何困难，能够克服千难万阻，茁壮地长成一棵参天大树!

小时候，他们被种植在不起眼的地方，没人关注。通过不断地吸取大地养分，阳光的普照，甘霖的降临，努力地成长。等到有一天，它们的成长被人看到，就会被移植到豪华的地段。经过护卫人员悉心照顾，被修剪成大家喜欢的形状，吸引更多的眼球，为城市增添绿色，为道路铺装绿色。吸收空气的二氧化碳，净化空气，无私地奉献氧气。当有一天，他不再拥有昔日光辉，就会被替换掉，或者直接走向生命的尽头!

人生何尝不是这样啊?小时候就是不断地学习，长大之后就是默默地工作。虽然这段旅途大家走的都不容易，但是我们有好多的相同之处。就像工作了，虽然不开心，但还要假装很快乐。为了生活，房子，车子等等，我们只能擦干眼泪，忍受孤独，做着像牛像马的活，放弃自尊，努力生活在城市的边缘，社会的底层!

早就听说中国红壤农业博览园风景美、是江西蔬菜水果的实验基地，3月29日这天，小主人报组织我们去那儿植树。

一大早我就赶到了集合地点，时间就像一只老蜗牛，一点儿也不急地向前爬去。盼呀盼呀，终于，我们等到了老师的出发指令。

到达了博览园，一下车，大家合影之后，就开始分头行动了！讲解员是李博士，他让我们边看边听，茂密的茶园，在绿油油的茶树之间挺立着一棵棵樟树，美丽极了！前方的落山含笑，花朵正在对着我们频频点头呢！一户人家家里还种了枇杷树，那小巧玲珑的枇杷树，可真可爱，它们矮矮的，长得多像七个小矮人一样。

不知走了多久，我们来到了智慧大棚，之所以叫做智慧大棚，是因为它可以按照蔬菜水果所需要的气候，来调节温度和湿度。我们在里面吃了顿午饭，还领取了一株嫩绿的小树苗儿。李博士带我们来到了一片宽阔的土地上，他告诉我们，这种小树苗儿叫做八月桂，并教我们植八月桂的步骤，先用铲子铲大约20厘米土坑，再放上小树苗儿，把土盖上，再用脚踩踏实，一棵小树苗儿就种好啦！

听完了讲解，我和小组成员就忙了起来，三人铲土，两人浇水，按老师说的那样，连种了五棵小树苗儿，老师也连连赞扬我们种得好！种完了树后，我们就拿出了一根丝带，然后我写上“邱欣昀，祝你和我幸福、平安！”这几个字系在树苗上，代表着小树苗儿，会在我的祝福下成长……

希望小树苗儿在专业人员的培育下更美，更茁壮！

在记忆中，小学食堂旁的几棵枇杷树不可抹灭。“那是什么树啊？为什么光秃秃的，现在不是夏天吗？”刚入学一个月，我就拉着科学老师到那枇杷树下。我从开学就开始注意他，总觉得他丑极了。“哦，那个啊，那个是枇杷树啊。”“原来枇杷树是这样的啊，，为什么他没有结枇杷呢？”“还没有到时候把。”于是，那天我的日记本，写上了那么一行：枇杷树是世界上最难看的树，以后我再也不吃枇杷了。

“看，枇杷就要成熟了呢！成熟时我们一起去摘来吃吧！”我对那人淡淡一笑，心里想着一年级时的那短短日记。过了几天，午饭后是不是看见有人去摘枇杷。他们知道树顶的枇杷最甜最好吃，但又摘不到，只好用脚去踢那可怜的枇杷树，试图把枇杷抖下来。我不忍心看，便每每吃完饭就头也不回的回教室。而那时骂我也明白了枇杷树沧桑的原因了。

不知不觉便六年级了，A焦急的跑到我家，说她妹妹生病了，听说有一个土方法要用枇杷叶，她便想起了学校的枇杷树。于是我们一起去了学校，经过老师的同意，来到了枇杷树下。那是我第二次那么近的望着它。它的枝条很稀疏地舒展着，似乎在说：来摘吧，孩子，我不怕痛的，只希望你弟弟的病能好。

那天下午，金色的阳光斜射在它身上，它似乎更沧桑了。我俯下身，捡起那些并未发黄的叶子，抚摸着它那被无知孩子踢出来的伤痕……

枇杷树啊枇杷树，你知道我对你的深深歉意妈？那天离开你时，望着你那沧桑的笑脸，有的不再是厌恶，而是一种钦佩！

其实，老师不正像那枇杷树吗？全心全意为了学生，呵护学生。他们不惜自己的身体把自己的知识一丝不苟的传授给学生。换来的是多少学生的抱怨？多少学生的怨恨？到最终，哪怕孩子们都觉悟了，明白了老师的爱，看到的只是老师那累累伤痕和丝丝白发了……

The proverb "Haste makes waste" means that one may delay the time to complete one thing if he rushes to do it, because he may neglect something important in the process and has to do it again from the beginning. So one should do every step well.

Take remembering English words for example, every student wants to enlarge his vocabulary. But this aim cannot be achieved in one or two days. You should stick to remem bering some words a day and revise the words every few days. In this way you can keep the words in your mind firmly. There is mo shortcut. If you want to stuff all the words into your brain and mot to revise them, you will remember nothing. So dont be hasty. Haste makes waste.

为了提倡孙中山先生“保护环境，植树造林”的宗旨，将孙中山先生逝世的那一天定位每年的植树节。于是每年的3月12日，就是全国的植树节。

在这个节日里，三墩镇中心小学的师生们一起行动起来了。他们以“行动起来，争做绿色小使者”为口号，将3月12日至4月12日定为植树月，将展开为期一个月的绿色行动。

3月9日的午间谈话时间，由各个班的班主任或者学生来介绍植树节，包括植树节的日子，由来，意义等。而601班则由黄子涵同学来介绍，他们班十分有创新，利用问答的方式激起同学们的兴趣。只见黄子涵在台上讲，台下的同学们都听得津津有味。黄子涵问的问题，台下的同学都能积极参与进来，达到效果。

这几天，班里陆陆续续有同学带绿色植物来学校，放在班里的绿化角。这也是学校的一项绿色行动。有的同学带吊兰，仙人掌……别的班级的许多同学还带来了好闻的花，走在学校的走廊里，静静地，你还能闻到芬芳的花香呢!

接下来，学校还将开展一系列的活动：

各个中队成立添绿小组;

我为校园添绿：开展捡垃圾、落叶、擦花坛、养护绿化(清理垃圾、修剪枝叶、擦树牌、松松土、拔拔草)等活动

我为家庭添绿：在自家房前屋后栽种一些小树木，养殖一些小盆景。

开展以保护环境为主题的编报比赛活动;

校大队部组织进行添绿、护绿活动展板评比活动

……

相信经过一系列的添绿行动和植物养护实践体验活动，能让我们三墩小学的所有同学们人人参与，在活动中体验成功的喜悦，增加对植物生长的了解，增强环保意识、生态意识，并达到美化校园、美化环境、为祖国增添绿色，为地球增添绿色的目的。

科学无处不在，在书中，生活中，头脑里等等。今天我为大家讲讲生活中科学家的故事。

我国伟大的科学家张衡于公元78年出身在荆州南阳，也就是现在的河南省南阳市。他从小就博览群书。十五岁的时候，便告别家乡出外游学。他先入武关，游三辅。十七岁的时候，他去洛阳的途中，登上了骊山峰顶。面对广阔的天地和壮丽的山河，他感到了前所未有的自豪和无限的感慨。下山的时候，他又去神进温泉游泳。此次游览，张衡对京都附近的自然景观，历史风貌，社会人情，学术情况都有了初步的了解和认识，也丰富了自己的人生经历。

不久，张衡到了都城洛阳，进入朝廷办的太学堂读书。他把全部的精力都放在专研典籍和与一些志同道合的朋友讨论问题上。张衡的家庭很贫困，平时的吃穿用都十分节俭。冬夜里，他只盖一条破被子，蜷曲者身子在灯光下读书。因为没有鞋穿，他的脚时常冻得红肿，乃至化脓溃烂，但他都咬着牙坚持。

张衡经常观察日月星辰，探索它们在天空里运行的规律。他把研究的结果写成一本书，叫做《灵宪》。在这本书里，他已经用了赤道，黄道，南极，北极等名词。他记录了二千五百颗恒星，并且画出了中国第一张完备的星图。他已经知道，月亮本身是不发光的，是受了太阳的折射才反出光来，月亮的黑暗部分，就是没有照射到太阳光的部分。所以月亮的位置和太阳相对的时候，是满月：月亮运行到跟太阳同一个方向的时候，人们就看不见他了。他还根据太阳在天空里运行的规律，解释了冬天日短夜长，夏天日长夜短的道理。他说天好像鸡蛋壳，包在地的外面：地像鸡蛋黄，在天的中间。这种假设叫做浑天说。后来张衡造出了混天灵。公元132年，张衡发明了世界上第一架测定地震的仪器，地动议。这些发明都在世界科学家发展史上留下不朽的篇章，也为我国科学技术的发展做出了杰出的贡献。
