Unit 8 绝妙的工具辛西娅·格雷巴如果没有望远镜，伽利略会有什么发现？如果没有杠杆，阿基米德能有什么成就？拥有合适的工具至关重要。
有时候，它们会在意想不到的领域被发现。
有时候，它们则就在你的眼皮底下。
1.你是否有过需要从高架子上取东西的经历？如果没有梯子，你或许会使用一把椅子。
当然（正如母亲曾告诉过你的）椅子是用来坐的，但是其平坦而高起的座位也很适合站在上面，这样你就够得着书架了。
2.科学家们有时候面临同样的问题，在回答或解决问题时没有合适的工具。
有时候，他们发明新的工具；有时候，他们则对已有的工具进行改造，以适应新的用途。
3.为了证明闪电其实就是电流，本·富兰克林在风筝上拴了一把钥匙，然后放飞到暴风雨中。
他的实验工具是由一个玩具和他家前门的一把钥匙制成的。
但是他从另一个角度看到：风筝可以把一根线带到暴风雨中，钥匙则是小小的导电体，上面还有一个洞，可以很方便地拴到风筝上。
一件新工具就这样诞生了!4.看一看其他领域的科学家如何使用他们绝妙的工具给人启示，一个问题可以从新的角度去看待。
展现历史5.在西班牙境内的罗马古城伊埃索遗址工作的考古学家在靠近城墙的底层发现了一个由黏土制成的酒坛（称为“双耳细颈椭圆土罐”）。
他们认为，建造这座城市的罗马人很可能也把葡萄酒从罗马带了过来。
6.只要科学家们能发现酒坛的年代，也就能推算出这座城市的历史。
当时的酿酒人往往会在酒坛上刻上酿酒当年的罗马执政官的名字。
同时，我们也掌握着每一对罗马执政官执政时间的可靠记录。
7.在这只酒坛的颈部有几个模糊不清的颜料印记，科学家们只辨认出了第一个名字的首字母Q.FAB，于是他们想到了“昆特斯·费比斯”这个名字，但是有两位在不同年代统治罗马的执政官都叫这个名字，因此，科学家需要找到与Q.FAB共同统治的另一位执行官的名字来确定这座城市的年代。
由于时代久远，再加上日晒雨淋，颜料已经剥落，第二个名字完全消失了。
