　　Once a baby cries, the parents will go to see what happened as soon as possible．According to a new study, a baby's cry can make adults react(反应)very quickly, even if they are not related．

　　Oxford University researchers used the classic game whack-a-mole for the study．Whack-a-mole(打鼹鼠游戏)requires people to hit one of nine buttons(按钮)．The players must react as quickly as they can to whichever of the buttons lights up at random(随机)．It is a game that requires speed and accuracy(准确度)．

　　The study included 40 men and women volunteers aged 19 to 59．Some of them had sons or daughters but none had a baby at the time．They played whack-a-mole after listening to different sounds, including babies crying, the crying of adults in trouble and birdsong played at a similar pitch to the babies' cries．

　　The volunteers' scores were higher after listening to the sound of crying babies．Men and women had similar scores overall．The results showed that a crying baby gets special attention．

　　"Few sounds make people react quite like the cry of a baby," said Morten Kringelbach of Oxford's psychiatry(精神病学)department, who led the study．"For example, it's almost impossible to ignore(忽视，不理)crying babies on planes．This is true even though there are so many other noises around．"

　　He added that a baby's cry can increase adults' heart rate and blood pressure．This is understandable, because in the course of human evolution(进化), taking care of babies has always been an important job for adults．When a baby is hungry or feeling bored or unwell, it will cry．As a result, human brains and bodies develop a special reaction to a baby's cry．

　　One day an American called Simon went to London to visit his friend，Rick．Rick told him that his flat was on the first floor．When he arrived，Simon went straight to the first floor of the building．But he was told that there was no Rick on that floor．Do you know why?

　　In fact，the British call the first floor of a building the ground floor．The floor above the ground floor is the first floor，which Americans would call the second floor．

　　The story shows that there are a few culture differences between Britain and America，though the British and Americans both speak English．

　　The British usually hide their feelings．They seldom start a conversation with strangers．For example，on the train the British often spend their time reading newspapers or books．But Americans are quite different．They're more active and easier to talk with.

　　The British and Americans may use different terms　 for many things．The British usually use foot ball，eraser and mail while Americans prefer to use soccer， rubber and post．

　　This is not a diet．It's a simple way to lose weight~ And you don' t even have to give up the food you love or join a gym．You just follow some habits that thin people have．Keep them, and you'll become thin．

　　When you wake up in the morning, sit up slowly without using your hands．With legs straight out, bend(弯曲)forward until you feel sore in your back．It will burn about 10 calories(热量单位，卡路里)．

　　When you have a meal, order a clear soup, and have it before having the main food．In this way, you'll feel fuller, so you'll eat less when the main food comes．

　　Apples are full of fiber(纤维)and water, so your stomach will want less．The study shows that people who eat at least three, apples a day lose weight．

　　Every time you use the mobile phone, stand up and walk around．Heavy people sit on average(平均)two and a half hours more each day than thin people．This skill is very important as standing up and walking around will burn 50 or more calories．

　　Use these skills, and you will have a big weight loss．
