However, 　6__　 　someone has a map of the city and 　7　 　you the main roads and buildings, you may say, “ Oh, now I see . I can find my way with 　8__　 　trouble at all ”. Working in math is somewhat(有点儿) like trying to find your way 　9　 　a new city. Perhaps the words may tell you some 　　　information and you have 　10　 　it, but you can’t see any clear road 　11　 　the answers.

Maybe you 　12　 　a kind of map of the main roads in maths 　13__　 　you find your way. Explore(探究)what lies in maths, and 　14　 　to find

the main roads. They will 　15　 　you to the answer. If you can find the “map”, the maths problems will be easily worked out.
