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 ?。

Kate, I think it’s your turn to punt!Outside viewV/OHarvard University in Cambridge is one of the best universities in the world. We spoke to Alex Jude, the university’s Head of Communications. He explained that Harvard looks for the best and most talented students from around the world.AlexHarvard actually seeks students from around the world, the best students that we can find, to study chemistry, or study literature, or study government, or business. Our business school is particularly well-known around the world, as is the medical school and law school, so, um, and, and the Kennedy School of government, for the John F. Kennedy School of Government, so, er, we do seek very, very talented students and we have open doors for them.V/OWe asked five students at Harvard to tell us what kind of social life they have. AshleyUm, well relaxing is a little hard to do around here, but basically, I mean, I still, I, I live nearby anyway, so I see a lot of my friends, and … Um, there’s a good social life here if you look for it. I go to the gym, run. So that’s what I do.AdamIt is whatever you want it to be. It’s good. If you wanna go out party, do anything you can. If you wanna sit in your room and study all night like my friend over here, you can also do that.BrianSocially, like you said, it’s, it’s a lot of what you make it. Um, we don’t have fra ternities here, and so, you know, that’s, it’s obviously not as social. There’s not as many parties as there would be on another campus. Um, but on a Friday or Saturday night, there, there, there will be a party. Usually we end up studying until about 10 o’clock. And then we, and then we’ll go out and have fun maybe, or just watch a movie with friends, or, you know, whatever is going on for the night. JodieNot everyone would agree with me, obviously, but it’s, I think it’s a fun place to be.Int.Have you made a lot of friends?JodieOh, definitely.Int. ：Mm.JodieMany.Int.What, what do you do with your friends?JodieUm, well, I like to go to concerts. I’m in three music groups, so I have lots of rehearsals during the week for that. Um, just do, you know, some fun things, on the weekend.V/OWe asked the Harvard students if they use theInternet.AshleyUm, I, I use it a fairly good amount. Um, our library system is online, so I use that a lot. And a lot of my classes, you know, have to do research papers. You can find a lot of information on there, so.Int.So how often do you use it, a week, a day?AshleyUm, I use it probably on more of a weekly basis. Maybe three or four times a week. BrianOh yes, definitely. We live through the Internet actually. Well, I do a lot of research through the Internet, follow my stocks on the Internet. Um, well, even though e-mail is not officially Internet, we, that’s how we communicate a lot at college, so, through the e-mail.JohnUm, I use the internet mostly for, er, I’d say, sort of leisure purposes. I mean, I play, um, I use it for a lot of, I don’t, we don’t have TV in my room, so I use it, uh, uh, go to the CNN website, keep up on current events, things like that. Uh, I also, uh, you know, there’s some little games to play over the Internet. Um, just um, I go to /doc/7b7573332.htmlto see what’s happening, follow the Boston Red Sox, things like that. Um, I think a lot of courses use it to post things, but I, I don’t usually use it that much for research, or things. I tend to use the libraries for such things, so.Listening inPassage1V/OHi, I’m Nick Carter, and this is SUR, your university radio station. This morning we went around campus to ask freshers –now half-way through their first year –the question, “How are you finding uni?” Here are some of the answers we got. Speaker 1It’s cool. It’s everything I hoped it would be. I’m very ambitious, I want to be a journalist and I want to get to the top of the profession. I’ve started writing f or the university newspaper so I’ve got my foot on the ladder already. Speaker 2I’m working hard and the teaching is as good as I expected. And I’ve made some good friends. But I’m very homesick. I’m Nigerian and my family’s so far away.I went home at Christmas for a month – that really helped, but man, I miss my family so much.Speaker 3“How am I finding uni?” It’s great. It’s not perfect, nothing is, but, like, I’ve got a brilliant social life, just brilliant, and I’ve made lots of friends. For the first few months I just didn’t do, really enough work. But I – I talked about it with my parents and I’m working harder now and getting good grades. Speaker 4Actually, I’ve been quite lonely to be honest. I’m a bit shy … everyone else seemed to find it so easy to make friends straight away. But things have been better recently –yeah, they have. I’ve joined a couple of clubs and like, it really helps to get to know people when you have shared interests. So, yeah –I’m feeling a lot happier now.Speaker 5Uni’s great, I love it. My only problem –and it’s quite a big problem –is money. My parents are both unemployed so, you know, they can’t help me financially. My grant just isn’t –it’s just not enough for me to live on, so I’ve taken a part-time job as a waitress – a lot of people I know, like a lot, have had to do the same. I don’t want to have huge debts at the end.Speaker 6I love my subject, History, and I’m, I’m getting fantastic teaching here. I want to be a university lecturer and that means I have to get a first. I have a good social life but work definitely comes first for me.Passage2Oxford and Cambridge – two universities so similar that they are often spoken of together as“Oxbridge”. They’re both in the UK, fairly near London, and both regularly come top in any ranking of the world’s best universities.The two universities began within a century of each other. Oxford University, now 900 years old,was founded towards the end of the 11th century. In 1209 there was a dispute between the university and the townspeople of Oxford. As a result, some of the Oxford teachers left and founded a university in the town of Cambridge, some 84 miles away. Ever since then, the two institutions have been very competitive.Unlike most modern universities, both Oxford and Cambridge consist of a large number of colleges. Oxford has 39 and Cambridge 31. Many of these colleges have old and very beautiful architecture, and large numbers of tourists visit them.In all UK universities, you need good grades in the national exams taken at 18. But to get into Oxford and Cambridge, it’s not enough to get A grades in your exams. You also have to go for a long interview. In these interviews, students need to show that they are creative and capable of original thinking.Through the centuries, both universities have made huge contributions to British cultural life.They have produced great writers, world leaders and politicians. Cambridge, in particular, has produced scientists whose discoveries and inventions have changed our lives.Among the great university institutions is the world’s most famous debating society, the Oxford Union, where undergraduates get a chance to practise speaking in public. Cambridge’s comedy club Footlights has produced many first-class comedians, while some of the UK’s most famous actors and actresses began their careers at The Oxford University Dramatic Society, known as OUDS. Then there’s the Oxford and Cambridge Boat Race, which takes place every year in March or April, and is watched on television all over the UK.So with all this excellence in so many fields, it’s not surprising that the ambition of clever students all over the world is to attend either one of these great universities.Unit 2Inside viewConversation1Kate ：Come in. Hey, Janet.Janet ：Hi Kate, are you busy?Kate ：Yes, I’m just doing an essay. But it’s great to see you. So what’s new? Janet ：Well, nothing much.Kate ：You look a bit fed up. What’s bugging you?Janet ：Well, I had a phone call from my parents and it made me feel homesick. It happens everytime they call, and it gets me down.Kate ：I’m sorry to hear that. I know how you feel. I love speaking to my mum and dad, but Ialways feel miserable after the call.Janet ：My dad doesn’t say muc h, and I want to speak to him, but I wish I knew what to say.Kate ：Don’t let it get to you. My dad doesn’t say much on the phone either. I call, he answersthe phone, and says, “Hi, I’ll pass you to your mother.” It’s really irritating. Janet ：But I miss him and my mother a lot, and I like to hear his voice.Kate ：Just tell him what you’re up to.Janet ：Sometimes I feel as if I made a mistake leaving home and coming to Oxford. Sometimes I feel like a moody teenager. Kate ：Try not to worry about it, Janet. It’s normal to feel like that. I understand how you feel, butI bet everything will be fine next term. You’ll get used to it. Hey, why don’t you do what I do?Janet ：What’s that?Kate ：When my dad calls, I ask him for more money! He usually says no, but at least I getto hear his voice!Janet ：Maybe. I’m sorry to take up your time, Kate, but I must go now. Bye! Kate ：Wait a minute …!Conversation2Kate ：I think I may have upset Janet last night.Mark ：What happened?Kate ：She came to see me. I was busy doing an essay but I was really pleased to see her. She’d had a call from home, and said she was feeling homesick.Mark ：Poor kid! It must be tough on you guys, living so far away from home.Kate ：I tried to make her laugh, told her not to worry about it, and that it was normal to feel miserable. Suddenly she looked miserable, and then she got up and said, “I must go now” and left my room. It was really sudden. I felt as if I’d said something wrong.Mark ：Maybe she was just being polite. It was probably because she realized you were working and didn’t want to disturb you.Kate ：I just wonder if she found it difficult to talk about her feelings with me. Maybe I shouldn’thave tried to make her laugh? Perhaps she thought I wasn’t taking her seriously. Mark ：I wouldn’t worry about it. Put yourself in her shoes. How would you feel if you were a student at college in China?Kate ：I know. That’s why I feel bad. If only she had stayed longer! I wish I could have helped her more.Janet ：Hey, everyone!Mark ：Hi Janet, you look cheerful!Janet ：Yes, I’ve just got my essay back. I got an alpha minus!Kate ：What an amazing grade! Well done.Mark ：I’m really happy for you, Janet.Janet ：I feel on top of the world!Outside viewSebastienHi. I’m Sebastien. I’m from Germany. Um, the idea of IQ of a measure of your brain power has been around for a while, but recently there’s been this new idea of the EQ –your emotional quotient. And by now, it’s actually almost being regarded as more importan t. If you look at it, businesses will … Well, they will prefer employing people with great EQ. Well, of course, IQ cannot be disregarded, but um, EQ does have its importance as well. Uh, I believe that, um, … I mean, people, most people will have, um, their basic means of communicating with other people. Most people are somewhat socially adept, and just like most people have, you know, a basic general knowledge. But then, what I think really is the difference betweenIQ and EQ, I mean, you can have a “brainiac”, and they will be great at most things they do, but if you just can’t get along with him, if you just can’t communicate with him, I mean, you know, he’s not really that useful.KimHi. This is Kim. I’m originally from Korea, and I was raised in Ca lifornia. And today, we are going to talk about the differences between IQ and EQ – IQ meaning your intelligence, EQ meaning your emotions. Now, in … When I was, when I was a little, little boy in Korea, I had to take … I think I’d taken like two or three IQ tests before the age of ten, which is when I moved to California. So, I guess we stress a lot of importance on intelligence, on having great IQ scores. But after I moved to the States, I learnt how to associate with people, and along the linesthat this word EQ came up, you know, emotional, caring about … It’s basically how you deal with people, howyou make people feel, and how people make you feel.I think they’re equally as, as important, but it seems that in the Eastern world they kind of stress on that a lot more back in the days. But I think again, you know, now that with Internet and people are communicating so much faster, there’s a better mixture of the two I think. There’s a stress on EQ in Korea as well, and a stress on IQ in the States. Thank you.TedHello. My name is Ted, and I’m from the United States of America. Today, I’m going to talk a little bit about IQ or EQ – which is most important, or which is more important. Now, for a long time when I was growing up, people said, “IQ. What’s your IQ? Take an IQ test.” But then EQ, your emotions, how you interact with people, that became very important. And I think they’re …that people might be onto something with that, because your EQ – how you deal with people, how you interact with people –is important. Now, a big part of this, in my opinion, is listening.I know I’m talking a lot right now, but if you want to get along well with people, you have to listen to them, so just take a minute, maybe shut your mouth for a minute, and listen to others, and then you can understand and communicate with them in a better way. So, part of EQ, I think, is listening – listening to others – and it can be more important than IQ.Listening inPassage1PresenterWe’re fortunate to have as our guest to day Dr Jenna Hudson, who has just written a book about how colours affect us in our surroundings, especially in the world of advertising. It’s called Market Colours. Dr Hudson, which are the most common colours in advertising and marketing?Dr HudsonWell, of course, it depends what image the marketing team wish to project with their products. So for example, we often think of blue as a cold colour, but it also makes you feel peaceful, quiet, and it doesn’t suggest strong emotions. So it’s a favourite for banks and insurance companies, who wish to suggest the image that they are trustworthy. And for selling products, it’s often used tosuggest something is pure and fresh.What about red?You can sell almost anything with red. It’s a hot colour, which su ggests a feeling of energy and even passion. It grabs your attention, and can make people buy almost anything. You often see red on magazine covers. But if you use it too much, it lookscheap and may make people tired. And orange has a similar effect to re d, it’s upbeat and happy, it suggests pleasant feelings and images. Most people react well to orange, and it’s especially popular in advertising and on packaging for baked food. What about yellow, for instance?Yellow is the colour of sunshine and it’s a positive, happy colour, so it’s used a lot in advertising. But it’s also often used for warning signs, direction signs, and so on, where you have to read the message quickly and at a distance.What about less popular colours for advertising?Surprisingl y, green isn’t used much in advertising except for garden products. It’s friendly and restful. It can be cool and soothing, the colour of apples and mint, but it can also be quite strong and many people associate it with unpleasant ideas of decay or slimy creatures. But most colours are not primary colours, they’re a combination. Absolutely. So yellow-orange is common, and often used to give an impression of style and class, it looks like gold. But it’s not often used in letters because it’s not very strong. And yellow-green reminds people of feeling sick.Blue-green works well as a cool colour, suggesting freshness, and is sometimes used for toothpaste products, bathroom products, food and household cleaning products. It has many of the advantages of blue without the disadvantages of green. Fascinating.Thank you very much, DrScriptsHudson.

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。

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！

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。

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。
竖直笔画要直立且与横线相交。
四、书写规范除了正确的笔画顺序外，书写汉字二还应该遵循一些书写规范，以保证字形的美观和整齐。
以下是一些常见的书写规范：1. 字形比例：汉字二的字形应该保持适当的比例，横线和竖线的长度应该相对平衡，不宜过长或过短。
2. 笔画粗细：汉字二在书写时，横线和竖线的笔画宽度应该保持相对一致，不要出现明显的粗细不均。
3. 书写速度：书写汉字二时应尽量提高书写速度，以便提高书写效率和准确度。
可以通过反复练习和多次书写来提高书写速度。
五、书写技巧除了正确的笔画顺序和书写规范外，我们还可以采用一些书写技巧来提高汉字二的书写质量。
1. 练习常用字：汉字二作为一个常见字，我们可以通过多次书写和模仿来提高书写的技巧和速度。
2. 视频教学：现在网络上有许多提供汉字书写视频教学的资源，通过观看这些视频，我们可以学习到正确的字形和书写方法。
3. 使用规范字帖：规范字帖是一种专门用来练习书写汉字的工具。
使用规范字帖可以帮助我们掌握正确的字形和书写技巧。
六、总结正确书写汉字二是每个中国人都应该掌握的基本技能之一。
通过遵循正确的笔画顺序、书写规范和使用书写技巧，我们可以提高汉字二的书写质量和美观度。

图5 承台基坑开挖示意图图6 承台基坑平面图地梁高度基坑深度普遍为0.7mm，按1：0.3放坡开挖，槽底宽度为在梁宽两边各加600mm；边梁开挖深度为2m，此部分梁按1:0.75放坡，槽底宽度为梁宽两边各加800mm，开挖深度至垫层底。
图7 地梁基槽开挖示意图局部部位地梁密度较大，不宜逐个开挖，此部位地梁采用全面开挖方法进行土方开挖，以便于机械施工作业，加快进度。
全面开挖具体位置见图8所示。
图8 全面开挖及电梯井区域图在4区和7区分别有一个长约12m，宽约4m，深2m的电梯井基坑，该部位承台面标高为-1.90m，此部分开挖可连同相连承台一起开挖，开挖方法同承台土方开挖方法，边坡按1:0.75放坡，坑底开挖宽度宽出结构边线1000mm。
位置见图8中所示位置。
图9 电梯井土方开挖示意图5.2.5挖土要点1)相邻坑基开挖时，遵循先深后浅或同时进行的施工程序。
2)挖土自上而下分层分进行，每层1m左右，边挖边检查坑底宽度和坡度，不够时及时修整，每2m左右修一次坡，至设计标高，再统一进行一次修坡清底，检查坑底宽度和标高，要求段坑度凹凸不超过5cm。
3)基坑开挖时尽量防止对地基土的扰动。
人工挖土部分，如基坑挖好后不能立即进行下道工序时，则预留30cm一层土不挖，待下道工序开始在挖至设计标高。
机械开挖部分，为避免破坏基底土，采取在基底标高以上预留20cm一层人工清理。
4)局部边角部位、桩的周围等机械开挖不到的部位，应用少量人工配合开挖和清底、清坡，将松土清至机械作业半径范围内，再用机械装车运走或在旁边堆放。
5)挖土至坑底设计标高后及时由建设单位、质检单位、设计单位、监理单位等组织基槽验收，做好记录，如发现地基土质与地质勘察报告、设计要求不符时，与有关人员研究及时处理。
达到设计要求后，及时进行垫层施工，砌筑砖胎膜，每一块坑底的无垫层暴露时间严格控制在24h以内。
5.2.6异常情况处理1）开挖过程中，施工人员要随时注意观察基坑土质变化及边坡稳定情况，出现异常情况，立即报告。
2）场内如有暗浜或软弱夹层，应将於泥全部清除干净，用砂石分层夯实至设计标高；3）开挖过程中如遇滑坡迹象，应立即暂停施工，报告业主并主动采取应急措施，在转移工人的同时，将滑坡现场进行封锁；测量人员根据滑坡迹象设置观测点，以便观测坡体平面及竖向位移，为应急措施提供重要的原始资料。
5.3土方外运根据场地情况，2#厂房开挖土方拟运至二期空置场地堆放晾晒，待回填时运回回填，现场预留4米宽土方运输道路，从里往外后退式回填。
5.4土方回填5.4.1土方回填要求1）本工程土方回填主要是承台、基础梁、电梯井处砖胎膜周边回填。
回填顺序为先深后浅依次进行。
回填时间应待该处胎膜砌体达到一定强度，一般为2-3天。
回填土质为粘土，土质含水量一般以手握成团、落地开花为宜。
当含水量过大，应采取翻松、晾干、风干、换土回填、掺入干土或其他吸水性材料等措施，防止出现橡皮土。
如土料过干时，则应预先洒水湿润，增加压实遍数或使用较大功率的压实机械等措施。
回填采用人工回填为主，机械辅助。
2）承台及基础梁砖胎模施工完毕后，对其外侧进行回填，采用人工分层铺填，用电动打夯机分层夯实，每层虚铺厚度不得大于300mm。
当砖胎模外侧与基坑或基槽边坡的间距很小时，回填料可采用级配砂石，用短钢筋插捣密实。
首层板底垫层下土方大面积采用电动打夯机分层夯实。
5.4.2土方回填技术措施1）在夯实后对每层填土进行质量检查，采用环刀法取样测定土的干密度，求出土的密实度。
每层按100～500m²取样一组，取样部位在每层压实后的下半部。
2）回填时，应设置标高控制线，防止一次填土过厚，无法保证质量。
3）非机电设备操作人员不准擅自动用机电设备。
使用打夯机时，要两人操作，其中1人负责移动胶皮电线。
操作打夯机人员，必须戴绝缘手套，以防触电。
4）雨季施工时严格控制土的含水量，避免形成橡皮土。
6技术质量保证措施6.1质量保证措施1）在项目经理、总工程师领导下，由工程部各质量技术人员组成质量管理小组负责土方工程质量管理工作。
2）开工前组织全部进场人员学习施工方案，做好各级技术准备和技术交底工作。
