都知道APS就是一场博弈，那么我们追求的就是一次完美的“零和博弈”！
先从材料学开始，审核官一上来有很大几率会以lets talk about your major 开场，那么如何使你的开场b格很高，又不要给自己后续问题埋下太多不确定因素呢？
bingo！很多聪明的同学已经猜到了，从Types of Materials开场！
一个比较好的范例为：
Materials may be grouped in several ways. Scientists often classify materials by their state: solid, liquid, or gas. They also separate them into organic (once living) and inorganic (never living) materials.
即低调又有料，还不装。
ok接下来可以用连招继续刷存在感：
For industrial purposes, materials are divided into engineering materials or nonengineering materials. Engineering materials are those used in manufacture and become parts of products.
然后停顿一下，卖个萌微个笑。
Nonengineering materials are the chemicals,fuels,lubricantslubricants, and other materials used in the manufacturing process, which do not become part of the product.
然后不出意料，审核官就要开始问你工程材料的相关问题了，恭喜你成功拉到仇恨，金属合金，金属磁化，合金与纯金属，金属的重要特性，这些够你和他们周旋一会了
