Eastern Quakes can Trigger Big Shakes
In the first week of November 2011,people in central Oklahoma experienced more than two dozen earthquakes.The largest,a magnitude 5.6 quake,shook thousands of fans in a college football itadium, caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before.
Oklahoma is not an area of the country famous for its quakes.If you watch the news on TV,you will see reports about all sorts of natural disasters一hurricanes,tornadoes,flooding and wildfires,to name a few.But the most dangerous type of natural disaster,and also the most unpredictable,is the earthquake.
Researchers at the U.S.Geological Survey estimate that several million earthquakes rattle the globe each year.That mnay sound scary,but people don'I feel many of the tremors because they happen in remote and unpopulated regions.Many quakes happen under the ocean,and othlers have a very small magnitude,or shaking intensity.
A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23,2011,was felt from central Georgia to southeastern Canada.In iilany urbanl areas,including Washington,D.C.,dnd New York City(Wall Street shown),people crowded the streets while engineer inspected buildings.Credit: Wikimnedia/Alex Tahak.
Scientists know about small,remote quakes only because of very sensitive electronic devices called seis-mometers.These devices detect and measure the size of ground vibrations produced by earthquakes.
Altogether,USGS researchers use seismornetero to identify and locate about 20,000 earthquaks each year.
Although earthquakes can happen anywhere in the world,really big quakeg occur only in。erttiin areas.
The largest ones register a magnitude S or higher and happen, on average,only once each year.Such big ones typically occur along the edges of Earth’s tectonic plates.
Tectonic plates are huge pieces of Earth’s crust,sornetinies many kilometers thick.These plates cover our planet's surface ike a jigsaw puzzle.Often,jagged edges of these plates temporarily lock together.When riates jostle and serape past each other earthquakes occur.On。、crage,tectonic plates move very slowly一about the same speed as sour fingernails grow.
But sometimes earthquakes rumble through portions of the landscape far from a plate'S edges.Although less cxpcctcd,these"mid-plate"tremors can do substontaI damage,Some of the biggest known examples rattled the eastern haif of the United States two centuries ago.Today,scientists are still puzzling over why the quakes occurred and when similar ones nught occur.

Learn About Light
1 Ancient civilizations were amazed by the existence of light for thousands of years?The Greek philoso-phrrs believed that light was made up of countless,tiny particles that enter the human eye and create what we call vision.However,Empedocles and a Dutch scientist named Christian Huygens believed that light wag like a wave.According to them,light spread out and travelled like a straight line.This theory was accepted during the 19th century.
2 In 1905,Albert Einstein published a research paper in which he explained what is referred to as the photoelectric effect.This theory explains that particles make up light.The particles Einstein was referring to are weightless bundles（束）of electromagnetic（电磁）energy called photons（光子）.Today,scientists agree that light has a dual（二重）nature一it is part particle and part wave.It is a form of energy that allows us to see things around us.
3 Things that give off light are known as sources of light.During the day,the primary source of light is the sun.Other sources of light include stars,flames,flashllights,street lamps and glowing gases in glass tube.
4 When we draw the way light travels we always use straight lines.This is because normally light rays travel in a straight line.However,there are some instances that can change the path and even the nature of light.They are reflection,absorption,interference（干扰）,etc.
5 Physicists have attempted to measure the speed of light since the early times.In 1849,Hippolyte Fizeau conducted an experiment by directing a beam of light to a mirror located kilometers away and placed a rotating cogwheel（旋转齿轮）between the beam and the mirror.From the rate of rotation of the wheel,number of wheel'S teeth and distance of the mirror,he was able to calculate that the speed of light is 313 million meters per second.In a vacuum（真空）,however,the speed of light is 299,792,458 meters per second.This is about a million times faster than the speed of an airplane.

Graphene' s Superstrength
Big technology comes in tiny packages.New ccii phones and personal computers get snialler every year,which means these electronics require even smaller components on the inside.Engineer; are looking for creative ways to build these components,and they'ye turned their eyes to graphene,a superthin material,made of carbon,that could change the future of electronics.
This year's Nobel Prize for Physics has been awarded to Andre Geim and Kostya Novoselov from the University of Manchester,U.K.for the discovery of graphene.Graphdne isn't just small;it's "the thinnest possible material in this world"says Novosclov.iJe calls it a “wonder material".It’s so thin that you would need to stack about 25,000 sheets just to make a pile as thick as a piece of' ordinary white paper.If you were to hold a sheet of graphene in your fingers,you'ci have no idea because you wouldn't be able to see it.
Carbon is one of the most abundant elements in the universe.Every known kind of life contains carbon.
Graphene is a sheet of earboti,but only one atom thick.You don't have to look far to find graphene一it's all around you.
If you want this high-tech wonder stuff,all you need is a pencil,paper and a little adhesive tape.Use the pencil to shade a small area on the paper,and then apply a small piece of adhesive tape over the area.
When you pull up the tape,you'll see that it pulls up a thin layer of some of the shading from your pencil.
That layer is called graphite,one of the softest mninerals in the world.
Now stick the same piece of tape on another sheet of paper and pull the tape up一there should be an even thinner layer,this time left on the paper.Now imagine that you do this over and over,until you get the thinnest possible layer of material on the paper.This layer would he only one atom thick,and you wouldn't be able to see it.Graphite is made of layers of graphene.So when you get to the thinnest possible layer,you've found graphene.

Puerto Rican Cuisine（菜肴）
Puerto Rico , a Caribbean（加勒比海区）island rich in history and remarkable natural beauty , has a cuisine all its own.Immigratjon（移民）to the island has helped to shape itscui、i ne, with people from all over the world making various contributions to it．However,before time arrival of these immigrants,the Taino people lived on the island of Puerto Rico.Taino cuisine included such foods as rodents（啮齿动物）,fresh shellfish and fish fried in corn oil.
Many aspects of Taino cuisine continue today in Puerto Rican cooking,but it has been heavily influ-enced by the Spanish,who invaded Puerto Rico in 1508,and Africans,who were initially brought to Puerto Rico to work as slaves.Taino cooking styles were mixed with ideas brought by the Spanish arid Africono to create new dishes.The Spanish extended food choices by bringing cattle,pigs,goats,and sheep to the island.Africans also added to the island's food culture by introducing powerful,contrasting tastes in dishes.
In fact,much of the food Puerto Rico is now famous for一coffee,coconuts,and oranges一was actually im-ported by foreigners to the island.
A common assumption many people make about Puerto Rican food, is that it is very spic)（辛辣的）.It's true that chili peppers are popular;aij caballero in particular is a very hot chili pepper that Puerto Ricans enjoy.However,milder（微辣的）tastes are popular too,such as sofrito.As the base of many Puerto Rican dishes,sofrito is a sauce made from chopped onions,green bell peppers,sweet chili peppers,and a handful of other spices.It is fried in oil and then added to other dishes.

Archive Gallery: The Best of Bionics（仿生学）
Humans might be the most highly-evolved species on the planet,but most animals possess skills we can only dream of having.Imagine how much electricity we could save if we could see in the dark the way cats do.Imagine leaping from tree to tree like a monkey.Giraffes（长颈鹿）,which are otherwise calm and good-natured,sleep only 4.6 hours a day.
We realized a long,long time ago that nature provides the best blueprint（蓝图）for invention.We've borrowed canals from beavers（河狸）and reflectors from cat's eyes.Although the words "bionics" became popular only after the 1960s,history shows that nature has always provided ideas on solving everyday prob-lems.Our archives（档案）don't go back to the time of Leonardo da Vinci and his bird-like flying machines,but we can take you to the late 19th century,where we applied those same principles for building our first practical airplanes.
To prepare for their flight at Kitty Hawk,the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air.Their success inspired scores of successors to improve on the airplane by studying various aspects of nature,One of Orville Wright’、pupils caught and stuffed seagulls to examine their wingspan.Meanwhile,two French inventors examined spinning sycamore（美国梧桐）seeds in an effort to apply those same motions,reversed,to a helicopter.
Some examples are more obvious than others.The outside of the airplane designed by the Wright brothers looks like a minimalistic（简单抽象艺术）structure.On the other hand , Barney Connett ' s fish submarine（潜水艇）actually looks like a fish.
Some bio-inspired concepts have yet to be invented.In the 1960s，the US Army commissioned several university professors to conduct research on the motor skills of animals in hope of applying those same abili-ties to tanks.Tanks that run like horses or jump like grasshoppers（蚂昨）一sounds shocking,doesn't it?
But imagine how life would change if we could achieve that.

Forests for Cities
You are standing in a beautiful forest in Japan.The air is clean and it smells like plants and flowers.
There are 175 different kinds of trees,and 60 kinds of birds living here._______(46)You are down-town in the city of Nara,Japan,in Kasugayama Forest,the oldest urban forest in the world.It was started more than a thousand years ago,and today it',very popular with tourists and artists.
Cities around the world are working to protect their urban forests.Some urban forests are parks,and some are just streets with a lot of trees.But all urban forests have many good effects on the environment.
_________(47)They also stop the noise from heavy traffic.They even make the weather better because they make the air 3-5 degrees cooler,and they stop strong winds.
Urban forests also have many good effects on people.They make the city more beautiful.In a crowded area,they give people a place to relax and spend time in nature._________(48) In some countries,people are starting new urban forests.In England,there are now 1.3 million trees in an urban forest called Thames Chase,east of London.It was started in 1990,and it has grown very fast.
Walking and bicycle clubs use the forest,and there are programs for children and artists.______(49) Some older cities don't have space for a big urban forest,but planting trees on the streets makes the city better.Scientists found that commuters（通勤人员）feel more relaxed when they can see trees.Trees are even good for business._________(50)In the future,urban forests will become even more important as
our cities grow bigger.In the megacities（超大城市）of tomorrow,people will need more green space to live a comfortable life.Planting trees today will make our lives better in the future.

Cerms（细菌） on Banknotes
People in different countries use different types of money:yuan in China,pesos in Mexico,pounds in the United Kingdom,dollars in the United States,Australia and New Zealand.They may use different cur-rencies,but these countries,and probably all countries,still have one thing in ________(51):germs on the banknotes.
Scientists have been studying the germs on money for well over 100 years.At the turn of the 20th ______(52),some researchers began to suspect that germs living on money could spread disease.
Most studies of germy money have looked at the germs on the currency _________(53)one country.
In a new study,Frank Vriesekoop and other researchers compared the germ populations found on bills of dif-ferent ________(54） Vriesekoop is a microbiologist at the University of Ballarat in Australia.He led the study,which corn- pared the germ populations found on money _______（55)from 10 nations.The scientists studied 1,280
banknotes in total;all came from places where people buy food,like supermarkets,street vendors and cafes,________ (56)those businesses often rely on cash.
Overall,the Australian dollars hosted the fewest live bacteria一no more than 10 per square centimeter.
Chinese yuan had the________(57）一about 100 per square centimeter.Most of the germs on money probably would not cause harm.
What we call "paper money"________(58)isn'tmade from paper.The U.S.dollar,for example,
is printed on fabric that is mostly cotton.Different countries may use different
________(59)to print their money.Some of the currencies studied by Vriesekoop and his team,such as the American dollar,were made from cotton.Others were made from polymers.
The three_______(60)with the lowest numbers of bacteria were all printed on polymers.They included the Australian dollar,the New Zealand dollar and some Mexican pesos.
The_________(61)currencies were printed on fabric made mostly of cotton.Fewer germs lived on the polymer notes.This_______(62)suggests that germs have a harder time staying alive on polymer surfaces.Scientists need to do more studies to understand _________(63)germs live on money一and whether or not we need to be concerned.Vriesekoop is now starting a study that will______(64)the amounts of time bacteria can stay alive on different types of bills.
Whatever Vriesekoop finds,the fact remains:Paper money_________(65)germs.We should wash our hands after touching it.After all,you never know where your money's been.Or what's living on it.
