once we talk about the reference book ,different people hold dofferent opinions .
some people think that it will do a lot good for us to use a reference book .On one side ,we can get the exactly right answer to those questions in the textbooks ,in this way ,we can make our study effectively .On the other hand ,the reference can help us to review our study .we can check those we have not handled in the class and we can make the review allsidely .
but others dont agree .in their opinion ,the reference books are like drug ,once you depend on it ,you will be addicted .and some students would not study hard ,because they think that they can rely on the reference books .This will the teachers uneasy to teach ,students would look down on those teachers teaching the exact things in the reference books .
Above all ,i think ,we should take a good use of the reference books .Students need to work hard in the class ,and use the reference books when they are reviewing their lessons .In this way ,they can make the study better and better .
