所谓“题眼”就是题的“关键点” ,它通常是解题时的切入点 .一道数学题能否正确、迅速、合理获解 ,其前提是是否认真审题 ,找准了“题眼” .下面通过几例来说明如何寻找“题眼” .1　审视“题眼” ,找准关键词例 1　已知某数列前ｎ项和为ｎ3 ,并且前ｎ个偶数项的和为ｎ2 ( 4ｎ The so-called “eye” is the “key point” of the question. It is usually the starting point for solving the question. Whether a mathematics question can be correctly, quickly, and reasonably solved, the premise is whether to examine the question carefully and find out the “topic”. Here are a few examples to illustrate how to find the “eye”. .1 Look at the “eye” and identify the key words. Example 1 The first n items in a sequence are known as n3, and the sum of the first n even items is n2 ( 4n.
