学好物理真是一门技术活，光是各种概念就已经让人头大，更何况以英文的形式出现。
Alevel物理简答题看起来复杂多变，让人感到一头雾水，无所适从。但实际上，做这类题有一定的方法和技巧，只要熟练掌握，很多题都可以迎刃而解！
今天小编就给同学们分享Alevel物理独家简答题满分技巧，刷到你就赚到辣！
文字叙述题这类题中经常会出现一些关键词（command words），比如，'Define'，'State'，'Compare’，'Describe’等。今天我们就根据大纲中对这些Command words给出的明确的定义与描述，总结出一套答题思路，帮助同学们拿下重难点！
A formal statement is required or, if you give the defining equation,all terms in the equation must be explained. Where a ratio is involved, the ratio must be made clear. For example, density is mass per unit volume, not mass of unit volume. When defining a quantity, this should not be done in terms of units.
我们看到State/Define的简答题，虽然要求给出formal statement， 但是如果你给的是defining equation也一样拿分。
所以，就算背不全那么长的定义也没关系，最重要的是理解。
It requires candidates to provide both similarities and differences between things or concepts.
也就是说，对于’Compare”的简答题，我们需要明确的给出‘similarities’ 和'differences'。
只要能理解区分题目，得分也不是什么难事~
Set out the facts or characteristics. The description of a process should address what happens, and when and/ or where it happens.
*Describe”类的简答题，也是比较容易丢分的题。对于这类题，我们需要强调两点：”what happen“和 “when/ where it happens”。
举例说明：
首先， what happens: alternating p.d. is applied, magnetic field changes, alternating p.d. is induced.
其次，when/where it happens：在这里，我们需要指出”where it happens“。
Magnetic field 是在iron core里变化，the induced p.d.存在于secondary coil。最好，我们将这些点串起来：alternating p.d. applied in the primary coil causes the changing magnetic field, which induces alternating p.d. in the secondary coil. 对比出的答案，我们很容易拿到了full mark。
Set out reasons and/ or mechanisms to address why and/ or how something happens. For example, when asked to explain the change in rate of reaction seen on a graph, the expected response would suggest scientific reasons for any change seen, for example in terms of molecular collisions or enzymatic action.
对于需要explain的题目，我们需要就题干中发生的事情，给出物理机制或者原因。
Give:
a short answer is required without expla nation.
今天的分享到这里就告一段落啦~希望大家都能满意的成绩！
