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。
新概念2英语听力原文
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 ?。
2的书写方法
2的书写方法在日常生活中，我们经常会涉及到数字2的书写。
无论是在学习、工作还是生活中，正确的书写方法都是非常重要的。
下面，我们就来详细了解一下数字2的书写方法。

在手写时，我们也需要注意字迹工整、规范，避免出现潦草、模糊的情况。
此外，数字2的书写还需要注意与其他数字的区分。
在一些情况下，数字2可能会与字母z混淆，因此在书写时要特别小心，确保数字2的书写清晰可辨，不会引起误解。
总的来说，正确的数字2的书写方法对我们的学习、工作和生活都是非常重要的。
通过掌握数字2的基本形态、书写顺序和书写规范，我们能够更好地书写出整洁、规范的数字2，提高书写质量，避免出现错误和混淆。
希望大家能够重视数字2的书写方法，不断提升自己的书写水平，为自己的学习和工作增添亮点。
2 In the Laboratory
"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.
