下面就是小编给大家分享的初一下英语作文范文（共含12篇），希望大家喜欢!同时，但愿您也能像本文投稿人“唐堃”一样，积极向本站投稿分享好文章。
一、所教班级学生基本情况分析：
本届七年级学生刚入学时英语基础不高，经过上学期我们几位英语老师的不懈努力，七年段学生的基础知识得到了加强，学习态度也有所好转。但根据初一上学期期末考试情况来看，英语总体成绩仍落后于六中和四中。但是学生整体的惰性还是很强，自觉性很差。
另外，学生在情感态度，学习策略方面还存在诸多需要进一步解决的问题。例如：很多学生不能明确学习英语的目的，没有真正认识到学习英语的目的在于交流；有些同学在学习中缺乏小组合作意识；大多数同学没有养成良好的学习习惯，不能做好课前预习和课后复习，学习没有计划性和策略性；不善于发现和总结语言规律，不注意知识的巩固和积累。主要原因是没有激发学生学习英语的兴趣，学生觉得英语学习是一种负担，而不是一种乐趣。一部分学生没有掌握记忆单词的方法，连基本的单词听写也不过关，导致看不懂，听不懂，学不懂。学生的听力也还有待提高，在这方面失分也较多。主要是听的时间太少，接触英语的时间不多。
二、工作目标：
本学期主要是继续培养学生对英语的学习兴趣，(故事，讲时配以表情、动作来帮助理解课文，这样能使学生更容易掌握新课知，这也是一种有效的教学方法。还可采取多媒体创设情景、或利用实物投影等形式学习新课。
4、注重对学生进行培优扶差
多与后进生沟通，教学上和生活中注意因材施教，做到“一视同仁”，对其循循善诱，耐心教育；并帮助其克服自卑，增强信心，利用课余时间辅导其学习。要及时检查，及时补救。做到所学知识天天清，周周清。
5、多与学生的沟通与合作
平时多与学生进行思想交流，了解其思想动向，关心学生学习和生活中情况。努力构建一个民主、和谐，紧密合作的融洽师生关系。
6、不断地提高自己的业务能力和水平
平时多与同行交流，多向有经验有水平，能力强的教师学习，比如多听课，多看书，以不断地提高自己的能力和水平。
同时，多与备课组成员密切合，共同探讨，共同进步。向科组其他老师请教，做到勤学好问，认真做好日常的英语教学工作。
7、提高课堂教学质量
认真备课、上课，认真实施30+15的文华教学模式，提高每一堂课的教学质量，将有效课堂教学改革继续深入下去。
三、教学内容和时间
由初一备课组成员统一安排

下五子棋初一作文
今天下午，我和妈妈在一起下五子棋。游戏的规则是：黑方先下，白方后下，黑方的第一个棋子要下在黑点上，棋子下定后不能移动，当一方棋子无论横、竖、斜，五个棋子连成一条直线，就是胜利，我和妈妈规定要三局，三局两胜和三局三胜都算胜利。
我们定完游戏规则就开始下棋了，妈妈在下棋的时候很不专心，一边嗑瓜字，一边下棋，她只顾堵我的棋，但不知为自己的棋子成一条直线埋伏一条路。我都在一条没有任何一个妈妈的棋子阻挡下的线路上下了五个子，妈妈还是觉然不知。就这样我赢了第一局，我有些得意忘形，便开始胡乱下棋起来，但妈妈现在可不像这个样子了，她专心致志，聚精会神的看着我下的每一步棋，我们下很久还不分胜负，但是最终我还是败在妈妈的手下。开始下第三局了，这可是决定胜负的`一局，有了上次的失败我不敢掉以轻心，但为了赢这一局，我给妈妈“打了一场大战”我下到东，她下到西，我下到南，她下到北，谁也不负谁。突然，我眼珠一转，计上心来，用掉虎离山之计，我用我的子布了好几条线，让妈妈的注意力散开，然后我在趁热打铁，把我又布的那一条已经下了四个子而且没有妈妈棋子阻碍的那一条线上又下了一个子，妈妈看看了说：“又赢了啊……”
通过下这盘棋，我领悟出这样一个道理：做任何事情都要做到“胜不骄，败不馁”，学习更应该这样！
七里香（下）-初一作文
我按了一下发送键然后翘着大腿等着她的评论，但过了很久都没有什么回音，我发了N 条信息但都没有反应真是失望，看着电脑上的网页可以用三个字形容那就是“没心情”没想到我的A计划会如此开始如此结束。我结完帐从网吧出来感觉这样闷这才发现夏日以至。我低下头走着。“hi”一声在我的耳边响起，我看见她离我只有0.01公分然后和我擦身而过。我先是愣了一会儿，如果把那刻的我拍下来的话我的嘴一定是做O状而且还是大写的那种，接着我怀疑这是不是在拍洗发水的广告，前面有一根大柱子等着我走着撞过去，我点了一下头走过去之后才知道没有。我甚至有一点后悔，后悔当时没有上去和她聊几句，然后和她一起去逛街，可是现在已经是大势已去了!
残阳如血，我埋头做着理科的题目，一张纸条不知经过了多少人的手沾上了多少人的指纹然后传到我的手中上面的字漂亮极了，至少比我的“狂草”漂亮。“对不起，由于我下午有事所以走开了没有打开你的网页，能给我看你的原稿吗?
我“唰”地一下写了一张“多多指教”的字条夹在原稿里，然后走到她的面前地递给了她。“杜峰”狮吼般的声音传入了我的耳朵，我转过身来满脸胡须和钟馗一样的老班站在门口。糟糕我居然给忘了这是在上自习课。老班把我叫进了办公室然后脱下鞋子翘起二郎腿对我做思想工作，大概是因为王力宏代言的娃哈哈矿泉水喝完了吧!他终于放了我一码，临走前我真想夸他一句“老师你的脚真有男人味!”
经过上次的小说事件，我和她的关系亲密了很多，但总得来说也没有多大的发展。我的损友都说我有前途，俺们的政治也说了“前途是光明的道路是曲折的。终于在他们的怂恿下我准备发起继9.11后的9.12事件。
那天放学后是她扫地，我终于鼓起了勇气走到她的面前问她赏不赏脸一起吃顿饭，接着“唰“地一下在场的其他女同学看了过来。我知道她当时有多尴尬。接受又不是拒绝又怕伤害我。我真后悔自己选的时间和地点。终于她做出了决定问道：“姐妹们一起去好吗?”我只感觉天不转地转，不会吧!这么多的电灯炮得要我多少money啊!我用眼睛盯着她们试着威胁她们不要去，但她们一个个拿着扫把看上去比我更有型。不过他们还好识相没答应不然我连灭了她们的心都有。
从餐馆走出来，我们在街上闲逛着。突然她问我有没有看过会发光的蝴蝶。我说没有。
“你相信会有吗?”彬问道
“相信，那你呢?”
“我当然相信因为在我小的时候曾看过，真的很没，但自从那以后就再也没看过了。”她说的时候眼睛发着光然后有是一阵失落。
第二天我在学校的实验室里弄了磷粉，然后捉了一只蝴蝶。我试着想把它涂在蝴蝶身上使它发光但都是失败，反而我的手不小心沾了水和磷而受伤了，真是怎一个“苦”字了得。
终于她的生日到了，我给她送了一件礼物，虽然很轻但装满了我的希望和等待。
我走在马路上，手里拿着刚从她手上拿来的《七里香》，我小心翼翼地将它打开，首先出现在我眼前的不是周杰伦的`照片而是她的。我捧着它高兴极了，一路上串来跳去的。突然我的眼前一黑什么也看不见了，当我醒来的时候周围围满了人，他们似乎在说着同一个话题。我想问他们但当我搭他们的肩的时候我发现我居然碰不到他们的肩，我的手从他们的肩上透过，那里好象没有人能看得见我。我低下头看见了一张熟悉的脸，我这才确认我真的是死了。这时一个妙龄少女端着一碗汤走到我的面前说：“该喝汤了。”我问：“是孟婆汤吗?”她点了点头。
“那你就是孟婆了?”
她说：“我不是，孟婆是我奶奶，她病了。我是在替她的班。”
靠!怪不得了，有这么漂亮的少女在黑白无常和牛头马面怎么能不下岗呢?我端汤热呼呼的我看着地上的《七里香》和旁边的照片。我闭上眼睛往嘴里灌。
咦!奇怪了孟婆汤里怎么有东西可以咬啊!我睁开自己的眼睛发现我正躺在自己的床上嘴里还咬着被子。哦!我恍然大悟冒了一身的冷汗。打开收音机。
窗外的麻雀 在电线杆上多嘴
你说这一句 很有夏天的感觉
手中的铅笔 在纸上来来回回
我用几行字形容你是我的谁
秋刀鱼 的滋味 猫跟你都想了解
初恋的香味就这样被我们寻回
那温暖 的阳光 像刚摘的鲜艳草莓
你说你舍不得吃掉这一种感觉
雨下整夜 我的爱溢出就像雨水
院子落叶 跟我的思念厚厚一迭
几句是非 也无法将我的热情冷却
你出现在我诗的每一页
雨下整夜 我的爱溢出就像雨水
窗台蝴蝶 像诗里纷飞的美丽章节
我接着写 把永远爱你写进诗的结尾
你是我唯一想要的了解
那饱满 的稻穗 幸福了这个季节
而你的脸颊像田里熟透的蕃茄
你突然 对我说 七里香的名字很美
我此刻却只想亲吻你倔强的嘴
……..
