Things to Know about the UK 1From Buckingham Palace to Oxford,the UK is loaded with wonderful icons(标志)of past eras.But it has also modernized with confidence.It’s now better known for vibrant(充满活力的)cities with great nightlife and attraction.Fashions,fine dining,clubbing,shopping-the UK is among the world’s best. 2Most people have strong preconceptions about the British.But if you’re one of these people,you’d be wise to abandon those ideas.Visit a nightclub in one of the big cities,a football match,or a good local pub and you might more readily describe the English people as humorous and hospitable.It’s certainly true that no other country in the world has more bird-watchers,sports supporters,pet owners and gardeners than the UK. 3Getting around England is pretty easy.Budget(廉价的)airlines like Easyjet and Rynnair fly domestically.Trains can deliver you very efficiently from one major city to another.Long distance express buses are called coaches.Where coaches and buses run on the same route,coaches are more expensive (though quicker) than buses.London’s famous black cabs are excellent but expensive.Minicabs are cheaper competitors,with freelance(个体的)drivers.But usually you need to give a call first.London’s underground is called the Tube.It’s very convenient and can get you to almost any part of the city. 4The UK is not famous for its food.But you still need to know some of the traditional English foods.The most famous must be fish and chips.The fish and chips are deep fried in flour.English breakfast is something you need to try.It is fried bacon,sausages,fried eggs,black pudding,fried tomatoes,fried bread and baked beans,with toast and a pot of tea.Other things like shepherd’s pie and Yorkshire pudding are also well-known as a part of English food culture. 5Pubbing and clubbing are the main forms of English nightlife,especially for the young.Pubbing means going to a pub with friends,having drinks,and chatting.Clubbing is different from pubbing and includes going to a pub,or a place of music,or a bar,or any other places to gather with friends.Clubbing can be found everywhere.Usually there is some kind of dress code for clubbing,such as no jeans,no sportswear,or smart clubwear,while pubbing is much more casual.

When We Are Asleep Everyone dreams,but some peopole never recall their dreams,or do so very rarely.Other people always wake up with vivid recollections (记忆) of their dreams,though they forget them very quickly.In an average night of eight hours’ sleep,an average adult will dream for around one hundred minutes,probably having three to five dreams,each lasting from ten to thirty minutes. Scientists can detect when someone is having a dream by using an instrument which measures the electrical waves in the brain.During dreaming,these waves move more quickly.Breathing and pulse rate also increase,and there are rapid eye movements under the lids,just as though the dreamer were really looking at moving objects.These signs of dreaming have been detected in all mammals (哺 乳动物) studied,including dogs,monkeys,cats,and elephants,and also some birds and reptiles (爬行动物).This period of sleep is called the“D”state for around 50% of their sleep;the period reduces to around 25% by the age of 10. Dreams take the form of stories,but they may be strange and with incidents not connected,which make little sense.Dreams are seldom without people in them and they are usually about people we know.One estimate says that two-thirds of the“cast”of our dream dramas are friends and relations.Vision seems an essential part of dreams,except for people blind from birth.Sound and touch are senses also often aroused,but smell and taste are not frequently involved.In“normal”dreams,the dreamer may be taking part,or be only an observer.But he or she cannot control what happens in the dream. However,the dreamer does have control over one type of dream.This type of dream is called a“lucid”(清醒的) dream.Not everyone is a lucid dreamer.Some people are occasional lucid dreamers.Others can dream lucidly more or less all the time.In a lucid dream,the dreamer knows that he is dreaming. We rarely smell things in dreams.
Hitchhiking(搭车旅游) When I was in my teens(十几岁)and 20s,hitchhiking was a main form of long-distance transport.The kindness or curiosity of strangers（51）me all over Europe,North America,Asia and southern Africa.Some of the lift-givers became friends,many provided hospitality（52）the road. Not only did you find out much more about a country than（53）traveling by train or plane,but also there was that element of excitement about where you would finish up that night.Hitchhiking featured importantly in Western culture.It has books and songs about it.So what has happened to （54） A few years ago,I asked the same question about hitchhiking in a column on a newspaper.（55）of people from all over the world responded with their view on the state of hitchhiking. “If there is a hitchhiker’s （56）it must be lran,”came one reply.Rural lreland was recommended as a friendly place for hitchhiking,（57）was Quebec,Canada-“if you don’t mind being berated(严厉指责)for not speaking French.” But while hitchhiking was clearly still alive and well in many parts of the world,the （58）feeling was that throughout much of the west it was doomed(消亡). With so much news about crime in the media,people assumed that anyone on the open road without the money for even a bus ticket must present a danger.But do we（59）to be so wary both to hitchhike and to give a lift In Poland in the 1960s,（60）a Polish woman who e-mailed me,“the authorities introduced the Hitchhiker’s Booklet.The booklet contained coupons for drivers,so each time a driver（61）somebody,he or she received a coupon.At the end of the season,（62）who had picked up the most hikers were rewarded with various prizes.Everybody was hitchhiking then.” Surely this is a good idea for society.Hitchhiking would increase respect by breaking down（63）between strangers.It would help fight（64）warming by cutting down on fuel consumption as hitchhikers would be using existing fuels.It would also improve eductional standards by delivering instant（65）in geography,history,politics and sociology. 55（）
Robots May Allow Surgery in Space Small robots designed by University of Nebraska researchers may allow doctors on Earth to help perform surgery on patients in space. The tiny,wheeled robots,（51）are about 3 inches tall and as wide as a lipstick case,can be slipped into small incisions(切口)and computer-controlled by surgeons in different locations.Some robots are equipped（52）cameras and lights and can send images back to surgeons and others have surgical tools attached that can be（53）remotely. “We think this is going to （54）open surgery,”Dr Dmitry Oleynikov said at a news conference.Oleynikov is a （55）in computer-assisted surgery at the University of Nebraska Medical Center in Omaha. Officials hope that NASA will teach（56）to use the robots soon enough so that surgeries could one day be performed in space. On earth,the surgeons could control the robots themselves（57）other locations.For example,the robots could enable surgeons in other places to （58）on injured soldiers on the front line.Researchers plan tp seek federal regulatory（59）early nest year.Tests on animals have been successful,and tests on humans in England will begin very soon. The camera-carrying robots can provide（60）of affected areas and the ones with surgical tools will be able to maneuver(操控)inside the body in ways surgeons’ hands can’t.The views from the camera-carrying robots are （61）than the naked eye,because they（62）back color images that are magnified(放大).Because several robots can be inserted through one incision,they could reduce the amount and （63）of cuts needed for surgery,which would decrease recovery time.This is particularly（64）to those patients who have been debilitated(使虚弱)by long illness. Eventually,Oleynikov said,the tiny robots may enable surgeons to work without ever（65）their hands in patients’ bodies.“That’s the goal,”Oleynikov said.“It’s getting easier and easier.We can do even more with these devices.”
