试题分析：这篇短文主要通过三个例子来给我们讲述了思考的重要作用。
【1】A前面提到：我将思考一下。说这个是很容易的。空格后面的意思是：我们不能看到我们的想法、或听到、品尝到、或感觉到它们。可知此处表达的意思是：但是你知道什么样的伟大事情都来自思考吗？故选A。
【2】F根据上一句：他看见一个苹果从一棵树上落下来。根据空格后一句：后来，他发现地球、太阳月亮和星星保存在他们的地方。可知此处表达的意思是：他开始思考，为什么苹果落下来。故选F。
【3】C根据下句：他开思想。他想找出为什么水壶里的蒸汽移动了沉重的盖子。可知上句在说：一个叫詹姆斯·瓦特的男孩安静地坐在炉边, 看着茶壶的盖子,上下移动。故选C。
【4】E根据上句：当他长大以后，他改进了蒸汽机,以至于它可以很轻松地做很多马做的工作。可知下句在说：当你看到一个汽船、蒸气机时，记得他很可能从来就没有被建造，如果没有艰苦思考的人。故选E。
【5】B根据上句：当你有一个困难的课程要学习时，不要感到气馁。在你请求别人帮助以前先要自己思考。因此可知下句在说：思考,通过思考你将学会如何思考一些目的。故选B。
