What will you do when you are in a strange place?Suppose you are going to Boston and you have never visited the city before.If someone 21 you about the interesting places in the city,you begins to get some ideas of what you will see.But you don’t have a 22 idea of where these places are or of how to find 23 .However,24 someone has a map of the city and it 25 you the main roads and buildings,you may say,“Oh,now I see.I can find my way with 26 trouble at all.” Working in math is somewhat like trying to find your way in a new city.Perhaps the words may tell you some information that you have 27 ,but you can’t see any clear road 28 the answers.
Maybe you need to have a kind of map of the main roads in math to help you find your way.Explore (探索) what lies in math,and 29 to find the main roads.They will 30 you to the answer.If you can find the “map”,the math problems will be worked out easily.
