尊敬的家长朋友们：

根据国务院放假调休安排和我校实际，高三、复习班5月1日—5月2日放假，其余年级5月1日—5月5日放假。

美好的假期，离不开安全的陪伴，为使孩子度过一个“安全、健康、有益、愉快”的“五一”假期，请家长朋友们切实担负起假期里的安全责任，与孩子一起度过一个安全、充实的假期!

一、加强交通安全教育。教育孩子严守交通法规，不闯红灯，不违章骑车、飙车，不跨越隔离栏，不追逐打闹，禁坐无牌无证车辆和超载车辆。

二、加强食品卫生安全教育。教育孩子注意饮食卫生，不暴饮暴食，不食用“三无”、过期食品，不吃路边摊点的食物，不吃油炸腌制类食品，不随便吃零食、野果，防止食物中毒和病从口入。

三、加强疾病防控安全教育。春夏时节是一些肠道、虫媒传染病的高发时期，要教育孩子勤洗手、洗澡，不到人口密集、空气污染的场所，家中要常开窗通风，要让孩子适当参加体育锻炼，增强体质，做好季节病、流行病预防工作。

四、加强消防安全教育。及时排查家中电气安全隐患，教育孩子正确掌握家用电器、电子产品操作和使用方法，家中消毒尤其是使用酒精消毒时禁用明火，不在景点、林区动用明火，违规用火。

五、加强防溺水安全教育。天气再热，不到河塘去降温;水景再美，不到水中去体验;水性再好，没有保障别下水;别人再劝，不用生命去逞能。家长要做到孩子外出“四知”：知去向、知同伴、知活动、知归时。如发现子女有异常行为应立即予以询问、调查、制止，极早做好消除安全隐患工作。

六、加强防范高空坠落。做好高层建筑安全防护，加强阳台、窗户等防护措施，预防高空坠落事故。教育孩子不要向户外抛扔杂物，避免伤及他人。

七、加强社会活动安全教育。教育孩子不进营业性的游戏厅和网吧等场所，在家中上网也应加以引导，做到适时适量、文明上网，同时加强做好防拐骗、防诈骗教育;外出活动必须征得家长同意，不要独自与陌生人接触和出行;教育孩子自觉遵守社会公德，遵纪守法，不参与违法违纪活动。

八、加强出游安全教育。目前全球疫情蔓延的形势日趋严峻，国内输入型病例仍在增加，全国疫情防控“外防输入，内防反弹”的压力依然不小。建议家长朋友和孩子暂缓外出旅游计划，尽量不离开广安市域。若确需外出，按照上级有关部门要求，到中高风险等级地区，返广后须按规定报告所在乡镇(街道)，并按要求进行14天集中(居家)隔离，同时进行核酸检测，核酸检测阴性且14天后无异常方可返校;到低风险等级地区，须乘坐安全交通工具(建议不乘坐公共交通工具)，不参加聚集性活动。

九、关注孩子心理健康。家长要多与孩子双向平等谈心，充分尊重和理解孩子，杜绝宠爱、妥协、物质利诱和威吓等不正确的教育方式。若孩子在学习和生活上遇到问题，可与学校、老师加强沟通，共同对孩子进行疏导。若孩子出现心理异常行为或心理疾病，要对症施策，早做干预和治疗，切勿讳疾忌医。

安全第一，平安是福。保障孩子健康成长，关爱孩子的生命安全，是学校、社会和家庭共同的责任。让我们携起手来，克服麻痹侥幸的心理，牢固树立“安全第一、预防为主”的忧患意识，重视对孩子的安全教育与监护，在孩子的心中筑起一道安全防线，让孩子健康快乐成长。

顺祝各位家长身体健康，家庭幸福，工作顺心!感谢你对学校工作的支持与配合!

betweenAmericaandChina, which will begin at 9 o’clock and end at 11 o’clock on

Nov. 28th in Classroom 201 of the third teaching building.

As an expert in international culture, you must have a good knowledge of

the cultural differences betweenAmericaandChina, so we hope you could help us

increase our knowledge and clear some cultural confusion.

Could you please contact us in advance at Englishtec@163.com if you could

come to our culture festival? We are looking forward to your reply.

A tree has three main parts, the roots, the branches and the leaves. Under

the ground, the roots spread out so that the tree can stand firm. Above the

ground, the roots form the trunk, and the trunk supports the branches.

Near the top of the tree, the trunk divides into branches. At the top of

the tree, the leaves grow out of the branches. the leaves receive sunlight to

help the whole tree grow.

Hailey: Hey Johnny, you are looking extra cool today yeah! I am sure that

you could be the winner of this year’s best speech. The judge is the most

popular girl in school Janet Cross Ward! Good luck to you Johnny!

Johnny: Thanks Hailey and good luck to you too, I like the sash, ha!

Hailey and Johnny both thought that they were going to tie, but suddenly

their father said, “Hailey, Johnny, come here please!” “Coming,” said Hailey and

Johnny rushing towards their father, “Please help me open these packages the

teacher gave you.”

Hailey: Hey, Johnny I love packages, what do you think it is?

Johnny: Don’t know Hailey, but I guess that we will just have to find out

on our own by untying the knots to find out, because that is the best way.

Johnny began examining the knot and to untie it; at last he untied the knot

and found it inside a piece of paper, and on it were some words for the speech.

Hailey on the other hand was trying to untie the knot, but couldn’t do it just

like Johnny did; she became very, very frustrated.

Hailey: Oh! I wish that these silly people won’t tie these strings to

tight; I can’t even get it untied! Johnny, how did you do it? I’m

astonished?

Johnny: Oh, I just examined the knot to untie it, I love that idea!

Hailey still couldn’t untie it; at last she made up her own mind.

Hailey: That it is, I shall cut it up, and besides it is a package, right?

Oh how I wish I knew what is inside my package! Give a knife!

Johnny: Oh don’t cut it Hailey! What nice piece of string this is!

Hailey: What signifies a bit of thick string that is useless in the

future?

Johnny: It is whipcord, Hailey; don’t you know anything that this string

could be of use to us? This could even be our only hope in the future!

Hailey: Whipcord? Well then, what signifies a bit of whipcord; we don’t

even need it in our speech! Besides, the whipcord is a package string.

The speech began, Johnny read his lines perfectly, and even did a dance

with his string. For Hailey she read her lines perfectly but couldn’t do any

dance; and so the winner was no other than Johnny.

Hailey: Maybe the string made you lucky Johnny, but next time the string

will cause you trouble; I am warning you again Johnny.

The next month, there was an aim competition and Johnny is going to compete

with his sister Hailey. And so it is Johnny Vs Hailey. The competition began;

the only audience was Mr. Lolo.

Mr. Lolo: Okay, Hailey is first to aim with her bow; remember the rules, if

her string breaks there is no allowed borrowing!

And so Hailey was up, she aimed her bow at 8 and got 80 points; her second

aim landed on 9; and so she got 90+80=170 points! She was about to aim until her

string broke, Hailey had no other string to tie it onto, and so there a chance

that the audience Mr. Lolo would say…

Mr. Lolo: You’re out, Hailey! No prize for you, Hahahahahaha; okay, Johnny

your up! Wish you good luck! Break a leg! Ha!

And so Johnny was up, he lifted up his arrow and aimed perfectly on ten,

and so he got 100 points; his second aim missed and landed on 9; he got

100+90=190 points; he liked Hailey broke a string on the last aim too, and so

Mr. Lolo had another chance of saying the word…

Mr. Lolo: You’re out! Ha! No prize for you too, Hahahahahaha; okay…

Mr. Lolo didn’t even finished when Johnny pulled out the string from his

pocket and tied it onto the bow; then he made his aim and won the prize. Hailey

told Johnny after the competition…

Hailey: I’m sorry Johnny, I congratulate you! And you’re right, I should

have kept the string; next time I will keep one if I have a chance.

ear mr.wang,

i am writing to express my heartfelt gratitude. i am referring to that

unfortunate accident the other day, when i was knocked off my bike by a

taxi.

if it had not been for your timely assistance in giving me first aid, i

fear that the consequences might have been much serious. everyone agrees that it

was your quick-witted response in that emergency that has led to this

satisfactory outcome.

although nowadays people in mounting numbers talk about the need to be

unselfish, we see very few people practice what they preach. if there were more

people like you, the world would be a nicer place.

yours sincerely,

li ming

I like to listen to music very much, especially the English songs. My

favorite band is Coldplay. When I hear their classic song Yellow, I will be very

excited. The reason I like this band is that they have something different from

others. In their songs, they search about life. Listening to English songs also

can help me improve my English level.

Dear parents,

Now I know clearly that you both are expecting me anxiously. I can say

nothing but thanks to you both on this special occasion, because words have

failed me when I want to express my thanks to you both for the loving care you

have shown for me, especially since I went to Senior Three. These days I have

been studying hard and have made some progress. And everything has got along

well with my college entrance examination. I have performed my ability in this

exam. I hope you both can set your mind at rest.

After this exam, I intend to help you do some housework which I have seldom

done before. And I also mean to learn to cook in order to prepare a dinner for

you both in person.

My dear parents, everything is going on well with me and do have a

rest!

Best wishes,

Yours

尊敬的家长朋友：

您好！时间飞逝，转眼一个学期过去了，在您的关心支持下，我校各项工作取得了长足的进步，在此对您表示衷心的感谢。回忆这学期，孩子在度过了欢快的“六一儿童节”和我们共同的关注中，不知不觉又成长了许多，时间镌刻下孩子们前进的脚步，也记叙着各位家长和学校对孩子们殷切的期望及艰辛的付出。

丰富多彩的暑期生活即将开始了。为了让您的孩子度过一个安全、愉快、充实而有意义的假期，学校特提出以下几方面的建议，希望家长予以密切配合：

一、安全：请您提醒孩子树立安全意识，假期期间尽量不要外出，若外出必须事先征得家长同意。

1、家长要教育监管孩子假期不准私自下水游泳；不擅自与同学结伴外出游泳；不到无安全保障的水域游泳。

2、夏季是恶劣天气多发季节，望家长监管、预防溺水，预防泥石流，教育孩子不准私自到河边玩耍、垂钓；不强行经过滑坡险道，远离危房、危墙；不擅自过易发洪水险桥、河道。

3、雷雨天时家长要教育孩子远离带电设备或其他类似金属装置；不要拨打或接听电话，不使用电话线上网，最好拔掉电话线、闭路电视线，以免引雷入室，发生危险。

4、家长要对孩子进行交通安全知识教育，叮嘱孩子严格遵守交通规则，严禁乘坐无安全保障的“三无”车辆，确保出行安全。

5、夏季是肠道传染病高发季节，家长要高度重视预防夏季肠道传染病，教育子女养成良好的卫生习惯，预防疾病发生。要教育子女不随意外出闲游，不摘食食性不明的野果，以防食物中毒。

二、学习：为使全体学生在假期能生活有规律、学习有效果，学校特向全体学生提出了“广泛、自主、合作、有的放矢”的学习要求。

1、家长要指导和督促孩子完成学校布置的书面作业和自我复习、预习，既要防止有违素质教育的各种做法，又要杜绝放任自流、放松监管；学校将学生的暑期作业精心作了逐日安排，希望家长认真、耐心、细致地做好检查督促工作，以确保孩子能按时、认真地完成假期作业。

2、从现在开始就应该让孩子养成良好的自我规划的习惯，要有意识地培养孩子的自学能力和自控能力，为下一阶段的学习积蓄力量。学生在假期中除了认真完成教师布置的书面作业之外，还应该在家长的指导下，制定一个科学合理的读书，多读书，读好书，尤其是名篇名著，也选择一些优秀期刊，培养写读书笔记的习惯，每天将所读书刊的内容概括记下，摘抄名言警句，写下读后感想。以提高素养，提升品味，知书达理，不断完善自我。

3、引导孩子关心国内外大事和新闻，关注社会生活，要鼓励他们多看中央电视台的“新闻联播”、“百家讲坛”、“焦点访谈”等节目，少看或不看娱乐节目、少儿节目等。

4、不要轻信各类培训机构和辅导中心的宣传和承诺，不要轻易把孩子不负责任地推出家门，交给各类培训机构和辅导中心，以免影响孩子良好学习习惯的养成和独立思考能力的形成。

三、道德品质：配合学校加强对子女的思想道德教育，法制纪律教育和安全教育，引导他们自觉遵守公共场所秩序和社会公德，自觉遵守各项法律法规。

在校做个好学生，在家做个好孩子，在社会做个好公民。指导孩子养成健康生活习惯，抵制社会不良行为的引诱；不进电子游戏室、歌舞厅等营业性场所；在家严格控制上网时间，不登录、不浏览未成年人不宜的网站，自觉抵制不良信息的危害。不赌博、不吸烟、不喝酒；远离drug，珍爱生命；不参加封建迷信活动和邪教活动，做到文明休闲，健康娱乐。开学后不得将手机、小灵通以及MP3、MP4等电子设施带到学校！

温馨提示：

各位家长，今年暑假从7月5日开始，8月31日上午8:00学生到校报到上课。请您切实依法行使法律监护人的责任，履行家庭教育的重要职责，教育子女重视安全，珍惜生命，防止一切不安全事故的发生，为我们的学生――您的孩子能安全，健康成长而共同尽心尽力。祝您的孩子度过一个轻松，愉快而充实的假期!

Dear Mr. Williams,

Thank you for your letter of congratulation on my exam results. I was very pleased to hear from you. The results were a great relief. I did much better than I thought I would.

We are having a celebration party on Saturday 22 May and we shall be pleased if you can come. It is a party for me, but my parents and some of their old friends are joining in, so you will find "real people" as well as teenagers to talk to.

The party starts at half past six- drinks, and a buffet supper later. You said in your letter that youve given up driving, so my father will meet you with the car at San Mateo station. Please let me know what time your train arrives.

There is a good train back to San Palo at 10:30 and well arrange transport for you to catch that. I hope that wont be too late for you. It would be a pity if you had to leave while the party was still in full swing.

I do hope that you will be able to come.

Yours sincerely,

Lily Chen
