　　·complain about not being in a school play

　　·not be the No．1student in every subject except gym and drama(话剧)

　　Many westerners are shocked by the Tiger Mom, but they also question ber： bow can you raise your kids like that? But at the same time, the Chinese kids in such an environment are outstanding．They have perfect scores and perfect behaveor．And now, they are thanking their mom for the way of education she gave．

　　“What kind of kids do I want mine to bi? ” Many parents always question themselves

　　this．“ No pains, no gains．It is simple．When you want something, you have to suffer for if first．” Some parents agree with Amy．But not all the people think so, they just wish their children to be happy every day．

　　Have you ever heard an echo of your voice?

　　An echo is a reflected(反射)sound．Stand in a very large, empty hall with nothing on the walls．Then shout．The sounds you make will hit the walls and come back to you．The walls reflect the sounds．These reflected sounds are called “echoes”．

　　We can use reflected sound to make sound travel farther．Hold a watch about fifty centimeters from your ear．You cannot hear it．The sound of the watch travels a short way in all directions．It does not travel as far as your ear．You can make it travel to your ear by using a roll of cardboard(纸板筒)．

　　Make the roll of cardboard about fifty centimeters long．Put one end over your ear and hold the watch at the other．Now you can hear the watch because the sound has not gone in all directions．It is reflected down the roll to your ear．

　　A megaphone(喇叭筒)works in the same way．It makes sound travel farther．It reflects the sound into a beam which can travel a long way．In the ship, the sailor uses the megaphone to make his voice travel．Without the megaphone, his voice cannot travel far．

　　We use reflected sound in many ways．We use it to measure the depth of the sea, for example．Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them．

　　An atlas is a book of maps．Atlases are made with different kinds of information about different parts and areas of a country or the world．They are prepared for desk use or travel use．

　　Desk atlases are made for different groups of people with different needs．For example, students may use desk atlases to help learn geography, and other people may use desk atlases to study a place．A popular type of the latest atlas shows the recent fact of the world．New atlases are often carefully produced to help people learn about the changes, such as the name changes, boundary(边界)changes and other important new information．A desk atlas can also have some different maps of the same place．For example, an atlas may include maps showing population and important products of a place．

　　Travel atlases usually show the information about both natural and man-made features(特点)．So it is not surprising to find universities, airports, forests, rivers, roads as well as cities, towns and villages in them．A travel atlas is often the first thing people need when they want to start a trip in a strange place．It often has a map of a whole country, and a map with more special information of each important place in the country．Take the atlas of the United States as an example, it often has a map of the whole country and then a map of each of the fifty states．

　　A travel atlas may also point out the beautiful natural places．In the US, the atlas may include national parks such as the Yellow Stone Park and some others to show the beauty of nature and interesting places to tourists．
