我的揪痧瘾（2020、2）
我的揪痧瘾（2020、2）我的揪痧瘾医⽣在线⽹2008/12/1709:22来源：我叫⼩美，⼩时侯经常看见⼈们揪痧，但从没体验过，是在我⾼中后，有⼀次重感冒，吃药也不见好，晚上妈妈说我给你揪揪痧吧，我没说什么，妈妈就在我脖⼦后边揪开了，刚开始还不是很疼，但随着吧吧的揪痧声，妈妈的⼿劲越来越⼤，我疼的乱叫，妈妈说痧很重，必须得揪透了才⾏，不管我怎么喊叫，妈妈就是不停⼿，⽽且我越动她就越⽤⼒，我只好咬着⽛强忍着，妈妈从脖⼦⼀直连着揪到肩膀，⼜把整个后背都揪了个遍.我以为终于揪完了，可妈妈⼜在我前胸揪了起来，特别疼，我眼泪都出来了，可妈妈就是不⼿软，揪了⼀个多⼩时，只到把我上⾝揪的紫⿊紫⿊的没⼀块好地⽅才罢⼿，揪出我⼀⾝汗，可别说，揪完我就特轻松舒服了.从此以后我⼀感冒发烧的就让妈妈给揪，我还真喜欢上了这种痛并很快乐的感觉.隔⼀段时间不舒服了就让⽼妈给揪揪全⾝.后来结婚了，我很希望⽼公能给我好好揪⼀次，可他不喜欢揪，总也不给我揪，⽽且他不舒服也不让我给他揪.有⼀次我发烧，晚上实在难受的不⾏，让⽼公给揪揪他怎么也不肯，后来看我不⾏就给我在后背刮了刮痧，可我总觉的没有揪痧的过瘾.⽣完孩⼦后我落下了腰疼的⽑病，去诊所拔了⼏次罐后，感觉挺管⽤，⽼公看我腰疼的直不起来也很着急，后来我治我的腰学会了拔罐，经常在我腰疼的时候给我拔罐、⾛罐、按摩、揪痧等，现在⽼公拔罐揪痧的技术很⾼，不光给我整治腰，在我感冒的时候也会给我揪痧、拔罐，现在我⼜可以感受揪痧拔罐了。
在⽼公的经常拔罐按摩下我的腰疼的次数少多了。
在我的影响下⽼公也爱上了揪痧拔罐，在他不舒服的时候，我也会很体贴的为他揪痧拔罐，他也没那么怕疼了。
现在⽼公⼀不舒服就主动让我给他揪痧。
我们两经常是旧痕未去⼜添新伤，但我们都很快乐！⽼公有⼀次在外地感冒了给我打电话说：“⽼婆我越来越离不开你了，你要在我⾝边就可以给我揪痧了，我真的好难受。
”我说：“你以前不是怕疼⽼不让揪吗？现在想起我的好了？你到外边诊所拔拔罐吧！回来我给你揪。
周边地面 2
周边地面——对没有地下室的建筑指底层房间外墙内侧两米范围内的地面。
对有地下室埋墙的建筑，指从室外地面和埋墙的交线算起向下两米内为周边地面。
非周边地面——对没有地下室的房间指底层地面中周边地面以外的部分。
有地下室埋墙的建筑，非周边地面指埋墙和地面面积的和减去从室外地面和埋墙交线算起向下两米的面积。
关于周边地面和非周边地面的几点说明1．周边地面和非周边地面的定义周边地面指距外墙内表面2m以内的地面，其余部分划为非周边地面。
位于室外地面以下的外墙（地下室外墙）应从与室外地面相平的墙壁算起，往下2m范围内为周边地面，其余部分划为非周边地面。
2．节能标准中对周边地面和非周边地面传热阻的计算《民用建筑节能设计标准》（采暖居住部分）JGJ26-95和《公共建筑节能设计标准》GB50189-2005对周边地面和非周边地面热阻采用了不同的计算方法，应分别对待。
A) 居住建筑：换热阻计算依据来源于《供热工程》（贺平孙刚编著）。
由于室内热量通过地面传到室外的路程长短不同，即热阻值不同，靠近外墙的室内地面，距离室外路程短，热阻值小，传热量大，反之远离外墙的地面热阻值大，传热量小，离外墙8m以远的地面，传热量基本不变。
基于上述情况，在工程上一般采用近似方法计算，把地面沿外墙平行的方向分成四个计算地带（每2m为一个地带，8m以外地面按第四地带考虑），如图1示。
1) 对于贴土非保温地面（组成地面的各层材料导热系数λ都大于1.16W/m?℃），各地带的传热系数和换热阻如下：周边地面传热系数限值为0.52 W / m2·℃地区，考虑到非保温地面第一地带（周边地面）的传热系数为0.47 W / m2·℃，小于限值0.5 2W / m2·℃,可不做保温；非周边地面（第二、三、四地带）不做保温时传热系数最大值为0.23 W / m2·℃,小于限值0.3 W / m2·℃，同样也能满足非周边地面限值的要求。

Explaining Dinosaur Extinction Dinosaurs rapidly became extinct about 65 million years ago as part of a mass extinction known as the K-T event,because it is associated with a geological signature known as the K-T boundary,usually a thin band of sedimentation found in various parts of the world(K is the traditional abbreviation for the Cretaceous,derived from the German name Kreidezeit).Many explanations have been proposed for why dinosaurs became extinct.For example,some have blamed dinosaur extinction on the development of flowering plants,which were supposedly more difficult to digest and could have caused constipation or indigestion—except that flowering plants first evolved in the Early Cretaceous,about 60 million years before the dinosaurs died out.In fact,several scientists have suggested that the duckbill dinosaurs and homed dinosaurs,with their complex battery of grinding teeth,evolved to exploit this new resource of rapidly growing flowering plants Others have blamed extinction on competition from the mammals,which allegedly ate all the dinosaur eggs—except that mammals and dinosaurs appeared at the same time in the Late Triassic,about 190 million years ago,and there is no reason to believe that mammals suddenly acquired a taste for dinosaur eggs after 120 million years of coexistence Some explanations(such as the one stating that dinosaurs all died of diseases)fail because there is no way to scientifically test them,and they cannot move beyond the realm of speculation and guesswork. This focus on explaining dinosaur extinction misses an important point the extinction at the end of the Cretaceous was a global event that killed off organisms up and down the food chain.It wiped out many kinds of plankton in the ocean and many marine organisms that lived on the plankton at the base of the food chain.These included a variety of clams and snails,and especially the ammonites,a group of shelled squidlike creatures that dominated the Mesozoic seas and had survived many previous mass extinctions.The K-T event marked the end of the marine reptiles,such as the mosasaurs and the plesiosaurs,which were the largest creatures that had ever lived in the seas and which ruled the seas long before whales evolved.On land,there was also a crisis among the land plants,in addition to the disappearance of dinosaurs.So any event that can explain the destruction of the base of the food chain(plankton in the ocean,plants on land)can better explain what happened to organisms at the top of the food chain,such as the dinosaurs.By contrast,any explanation that focuses strictly on the dinosaurs completely misses the point The Cretaceous extinctions were a global phenomenon,and dinosaurs were just a part of a bigger picture. According to one theory,the Age of Dinosaurs ended suddenly 65 million years ago when a giant rock from space plummeted to Earth.Estimated to be ten to fifteen kilometers in diameter,this bolide(either a comet or an asteroid)was traveling at cosmic speeds of 20-70 kilometers per second,or 45,000-156,000 miles per hour.Sucha huge mass traveling at such tremendous speeds carries an enormous amount of energy.When the bolide struck this energy was released and generated a huge shock wave that leveled everything for thousands of kilometers around the impact and caused most of the landscape to burst into flames.The bolide struck an area of the Yucatan Peninsula of Mexico known as Chicxulub,excavating a crater 15-20 kilometers deep and at least 170 kilometers in diameter.The impact displaced huge volumes of seawater,causing much flood damage in the Caribbean.Meanwhile,the bolide itself excavated 100 cubic kilometers of rock and debris from the site,which rose to an altitude of 100 kilometers.Most of it fell back immediately,but some of it remained as dust in the atmosphere for months.This material,along with the smoke from the fires,shrouded Earth,creating a form of nuclear winter.According to computerized climate models,global temperatures fell to near the freezing point,photosynthesis halted,and most plants on land and in the sea died.With the bottom of the food chain destroyed,dinosaurs could not survive. paragraph 1 Dinosaurs rapidly became extinct about 65 million years ago as part of a mass extinction known as the K-T event,because it is associated with a geological signature known as the K-T boundary,usually a thin band of sedimentation found in various parts of the world(K is the traditional abbreviation for the Cretaceous,derived from the German name Kreidezeit).Many explanations have been proposed for why dinosaurs became extinct.For example,some have blamed dinosaur extinction on the development of flowering plants,which were supposedly more difficult to digest and could have caused constipation or indigestion—except that flowering plants first evolved in the Early Cretaceous,about 60 million years before the dinosaurs died out.In fact,several scientists have suggested that the duckbill dinosaurs and homed dinosaurs,with their complex battery of grinding teeth,evolved to exploit this new resource of rapidly growing flowering plants Others have blamed extinction on competition from the mammals,which allegedly ate all the dinosaur eggs—except that mammals and dinosaurs appeared at the same time in the Late Triassic,about 190 million years ago,and there is no reason to believe that mammals suddenly acquired a taste for dinosaur eggs after 120 million years of coexistence Some explanations(such as the one stating that dinosaurs all died of diseases)fail because there is no way to scientifically test them,and they cannot move beyond the realm of speculation and guesswork. 1.In paragraph 1,why does the author include a discussion of when flowering plants evolved? 【事实信息题】 A.To help explain why some scientists believe that the development of flowering plants led to dinosaur extinction。

20. Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything—not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'Y ou must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one impor tant thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all !21. Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The airport was built during the war, but for some reason it could not be used then. Last year, however, it came into use. Over a hundred people must have been driven away from their homes by the noise. I am one of the few people left. Sometimes I think this house will be knocked down by a passing plane. I have been offered a large sum of money to go away, but I am determined to stay here. Everybody says I must be mad and they are probably right.22. My daughter, Jane, never dreamed of receiving a letter from a girl of her own age in Holland. Last year, we were travelling across the Channel and Jane put a piece of paper with her name and address on it into a bottle. She threw the bottle into the sea. She never thought of it again, but ten months later, she received a letter from a girl in Holland. Both girls write to each other regularly now. However, they have decided to use the post-office. Letters will cost a litt1e more, but they will certainly travel faster.23. I had a letter from my sister yesterday. She lives in Nigeria. In her letter, she said that she would come to England next year. If she comes, she will get a surprise. We are now living in a beautiful new house in the country. Work on it had begun before my sister left. The house was com pleted five months ago. In my letter, I told her that she could stay with us. The house has many large rooms and there is a lovely garden. It is a very modern house, so it looks strange to some people. It must be the only modern house in the district.24. entered the hotel manager's office and sat down. I had just lost &50 and I felt very upset.' I left the money in my room,' I said, 'and it's not there now.' The manager was sympathetic, but he could do nothing. 'Everyone's losing money these days,' he said. He started to com plain about this wicked world but was interrupted by a knock at the door. A girl came in and put an envelope on his desk. It contained &5o. 'I found this outside this gentleman's room' she said. 'Well,' I said to the manager, 'there is still some honesty in this world !'25. I arrived in London at last. The railwaystation was big, black and dark. I did not know the way to my hotel, so I asked a porter. I not only spoke English verycarefully, but very clearly as well. The porter, however, could not understand me; I repeated my question several times and at last he understood. He answered me, but he spoke neither slowly nor clearly. 'I am a foreigner,' I said. Then he spoke slowly, but I could not under stand him. My teacher never spoke Eng- lish like that! The porter and I looked at each other and smiled. Then he said something and I understood it. 'Y ou'll soon learn English!' he said. I wonder. In England, each man speaks a different language. The English understand each other, but I don't understand them ! Do they speak English ?。

二进制的借位规则
感谢百度文库让我们在这里与你相见，您的下载就是我们最大的动力。
二进制的借位规则
一、二进制借位规则是啥呢？
咱都知道二进制就只有0和1这两个数字。
在做减法的时候，借位规则可有趣啦。
当0减去1的时候，就像一个小穷光蛋要给别人1个东西一样，它自己没有呀，那咋办呢？这时候就得向高位借位啦。
一借呢，这个0就变成了2（在二进制的概念里哦），然后2 - 1就等于1啦。
再比如说，像10 - 1这样的情况。
个位上0减1不够减，就向十位借1，借过来之后个位就变成了2，2 - 1 = 1，十位上原本是1，借出去1个就变成0啦，所以结果就是1。
反正呀，二进制的借位规则就是低位不够减就向高位借，借来之后就可以愉快地做减法啦。
哈哈。

"That is good,that is good!"he repeated,"but that is not all;go on."And so for three long days he placed that fish before my eyes,forbidding me to look at anything else,or to use any artificial aid."Look,look,look,"was his repeated instruction.
"When do you wish to begin?"
"Now,"I replied.
This seemed to please him,and with an energetic "Very well!"he reached from a shelf a huge jar of specimens in yellow alcohol."Take this fish,"he said,"and look at it;by and by I will ask what you have seen."With that he left me.I was disappointed,for gazing at a fish did not seem to be challenging enough to an eager student,and the alcolol had a very unpleasant smell.But I said nothing and began to work immediately.

幼儿园数字2的正确写法
《幼儿园数字 2 的正确写法》
小朋友们，今天咱们一起来学习数字 2 怎么写哟！
数字 2 呀，就像一只小鸭子在水里游呀游。
咱们先准备好小铅笔和小本子。
那怎么写呢？
先从上半部分开始，画一个小弯弯，就像小鸭子的头。
这个弯弯要圆滑一些，可不能有尖尖的角哦。
比如说，咱们可以想象成小鸭子在开心地抬头看天空。
然后呀，再接着画一个大大的弯弯，要连到上面的小弯弯，这就像小鸭子的身体啦。
这个大弯弯要写得大大的、长长的，就像小鸭子在水里舒展开身体游泳。
咱们来看看小明同学写的数字2，他一开始写的小弯弯太小啦，看起来就不像小鸭子的头，倒像是个小豆豆。
后来呀，小明认真观察老师写的，多练习了几次，终于写得像一只漂亮的小鸭子在游泳啦！
还有小花同学，她写数字 2 的时候，两个弯弯没有连在一起，看起来就像断了的小竹子，可不是好看的数字 2 哟。
小朋友们写数字 2 的时候，要慢慢地写，一笔一划，不要着急。
可以先在本子上多画几个小弯弯，找找感觉。
老师再给你们讲个小故事。
有一天，数字 1 和数字 2 一起去参加比赛，数字1 站得直直的，很快就累了。
数字 2 呢，舒舒服服地弯着腰，轻松又快乐。
所以呀，咱们写数字 2 的时候，也要让它舒舒服服地弯着。
大家多练习几次，相信每个小朋友都能写出漂亮的数字2！
写好了之后，可以拿给爸爸妈妈看，他们一定会夸奖你们的。
小朋友们，加油哟，咱们都能把数字 2 写得棒棒的！
好啦，关于数字 2 的正确写法就讲到这里，小朋友们快去练习吧！。
2是什么意思
2是什么意思
2是一个网络用语，通常有多种理解意思，可以理解为“爱”，理解为“笨”、“傻”的意思，也可以形容一个人很活泼开朗、幽默并且个性，还可以用来形容人呆住、无语。
众所周知，在网络中，2通常有多种理解意思，一种理解为“爱”，如数字串“520”=我爱你，数字串“5201314”=我爱你一生一世，数字串“258”=爱我吧，数字串“7758258”=亲亲我吧爱我吧，数字串“52410”=我爱死你了。
其他一种理解为“笨”、“傻”的意思。
例如250，2货。
这种意思的2来源于"62"，近似于杭州方言“盒子”，用来形容人脑袋空空比较笨。
另一种意思就是形容一个人很活泼开朗，很幽默并且个性，比如说：“很2很光芒”。
还有一种用来形容人呆住、无语的意思，如：看到这个成绩我瞬间就2了。
同时，在北京方言里，2也表示一种傻，脑子不灵活的意思。

【课⽂】 First listen and then answer the following question. 听录⾳，然后回答以下问题。
How much of each year do spiders spend killing insects? Why, you may wonder, should spiders be our friends? Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beasts who eat insects but all of them put together kill only a fraction of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, spiders never do the harm to us or our belongings. Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always has eight legs and an insect never more than six. How many spiders are engaged in this work on our behalf? One authority on spiders made a census of the spiders in grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre; that is something like 6,000,000 spiders of different kinds on a football pitch. Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country. 【New words and expressions ⽣词和短语】 insect n. 昆⾍ devour v. 吞⾷ flock n. ⽺群 herd n. 牧群 beast n. 野兽 fraction n. ⼩部分 census n. 统计数字 acre n. 英亩 content adj. 满⾜的 【课⽂注释】 1. you may wonder 是这个疑问句的插⼊语。
汉字二的正确写法
汉字二的正确写法汉字是中国人民的文字和文化传承的重要组成部分。
其中，汉字二作为一个常见的汉字，其正确的写法具有重要意义。
本文将探讨汉字"二"的正确写法，并提供一些书写规范和技巧。
一、笔画顺序汉字二是一个非常简单的汉字，只包含一笔，其笔画顺序非常重要。
正确的笔画顺序可以帮助书写者提高书写速度和书写准确度。
在书写汉字二时，我们应该先写横折笔画，再写竖直笔画。
二、横折笔画横折笔画是汉字二的主要组成部分。
横折笔画应该从左上角开始，向右下方倾斜，形成一个较长的横线。
横线的长度可以根据个人喜好和书写空间的限制来调整，但是要保持横线的平直和统一。
三、竖直笔画竖直笔画是汉字二的另一个组成部分。
竖直笔画应该从横折笔画的右下方开始，向下方延伸，长度与横折笔画保持一致或稍长一些。
