阶梯式

Contrastingly, if the sub-questions in asking steps are related with each other, and the answer of the previous sub-question can give a clue to the answer of the next one, i.e., the sub-questions are in proper sequence or ladder-like, it can help examinees understand the question and decrease the difficulty.

如果分步设问的各个小问题之间相互联系，前面问题的解决能够为后面问题的解决搭建阶梯，即分步设问的各个小问题之间是循序渐进的、阶梯式的，则可以有效帮助考生理清解题思路，从而使试题难度降低。
