Our School Activity Survey

<正>Here are the results of the students’activities in our school. Most students watch TV every day, some students watch TV 3 or 4 times a week. Some students aren’t interested in watching TV, so they watch TV only once or twice a week. As for reading English books, most students read English books every day. No students read English books 5 or 6 times a week.     

Sports and Health

<正>In the past,I hated exercise.My mother often advised me doing~(1)some sports.But I didn't accept her advice.I thought it tiring to do sports every day and it was very difficult for me to do some sports.So I was very weak and I often got ill.I also got fatter and fatter.I wanted to improve the situation.So I tried to do sports every day.It often took me one and a half hours to do sports every day.Now I love sports very much and I am very strong.I seldom catch a cold but~(2)I am not fat any more.I am also much strong~(3)."Life lies in movement." I hope everyone can learn from me.Do exercise every day.I believe everyone can be stronger and stronger.     

My Favourite TV Programme

<正>My favourite TV programme is Animal World.Firstly,I like animals very much.Secondly,the host has the ability to make the programme lively and interesting.Thirdly,from the programme I have got a lot of knowledge about nature and animals,which was unknown to me before.     

I Want to Invent a New Kind of Pen

<正>Inventions are created every day because people would like to make life easier.There are famous inventions like TV,computers and mobile phones.I want to invent a new kind of pen.If we have trouble in working out our problems,it can tell us like a teacher.It can also tell us what to do or not to do.If we are sad,it can cheer us up and encourage us like a good     

My Favourite Sport

<正>My name is Li Dongyang.I love playing basketball very much and I am good at it.I’m a member of the school basketball team.After school,I often play basketball with my classmates.I watch basketball games on TV every weekend.I love collecting pictures of     

My Ideal School

<正>My ideal school is really amazing.It has a big campus.There is a swimming pool and a beautiful garden in it.There is also a big playground for us to play.Class starts at 9:30 a.m.and finishes at 3:30 p.m.,so we don’t need to get up early.At lunchtime,we may have a good time chatting with our friends.We can choose any food we like.We don’t need to wear school uniforms every school day.We have a lot of clubs.     

江西省森林火灾发生特点及防治对策研究

基于ArcGIS、Excel 等空间分析和数学统计手段,对江西省2011-2018 年的森林火灾发生情况、起火原因、时空分布等特点进行研究,以此分析山地丘陵地区森林火灾动态特征。结果表明,江西省在此年间共发生火灾202 次,上坟烧纸、烧荒烧炭和野外吸烟是引发森林火灾的主要原因,分别占总数的29%、17%、14%;森林可燃物中主要以中熟林、幼龄林、杉木及马尾松为主要树种;森林火灾多集中在上半年,尤其1-4 月,下半年较少;每天的12-18 时为火灾高发时段,22 时至次日6 时火灾发生次数较少;上饶市、吉安市发生火灾次数最多,热点区域主要集中在上饶市117̊48′E,28̊19′N 处和萍乡市113̊46′E,27̊42′N 处。本研究可为山地丘陵地区林火管理工作提供理论支持。     

广州新电视塔挖孔桩岩层承压裂隙水处理

广州新电视塔工程主楼外框筒基础采用直径3.8m的人工挖孔桩,由于地处珠江边,珠江水通过岩层裂隙渗入到基础桩内,涌水量最大达到20m3/h.同时施工期间暴雨不断,使得人工挖孔桩施工困难大.通过借鉴已完成挖孔桩岩层裂隙水的经验,结合14号桩内涌水等特殊情况,对该桩提出并实施桩内降水、涌水引排的方案,取得良好效果,确保桩芯混凝土浇筑质量,符合设计要求.     

The New School Term

<正>I’m Li Jiaying,I’m in Grade Three this year.My life has changed a lot in the past few years.I used to get up at 7:00 in the morning.But now I get up at 6:00 and read English for half an hour every morning.I used to watch TV and go to bed at 9:30 in the evening.But now I keep doing my homework until 11:00 and then go to bed.I used to play basketball or tennis in my free     

电阻率法在深部巷道分区破裂探测中的应用

 淮南丁集煤矿西部采区南运输大巷埋深达955 m,已显现出深部开挖的特征。为研究深部巷道围岩破裂情况,在该巷道选取2个监测断面(宽5.0 m,高3.8 m),每个断面布置5个钻孔,测量围岩电阻率沿钻孔深度的变化。电阻率是岩石的重要电性参数,岩体的破碎程度对电阻率的影响较大,一般有裂纹的地方,电阻率产生突变。采用ResiTest–4000电阻率测试仪和研制的孔内探头,对钻孔内岩体电阻率进行测试。岩石破碎区电阻率基准值根据每一钻孔电阻率平均值(剔除特异点)确定,大于基准值的为破碎区。根据测试结果,绘制巷道围岩分区破裂图,与钻孔电视观测结果较吻合。结果表明,该巷道围岩有4个破裂分区;破裂分区带的半径与巷道半径基本呈线性关系;巷道周边破裂区宽度最大,平均达到3.12 m,依次分区破裂带的宽度有递减趋势。
