A-level物理：简答题如何做？锦秋支招！

在A-level物理中，简答题所占分值相对较大，如何在简答题部分获得高分呢？下面，锦秋小编为大家支招，在这里，我们总结经常出现的command words，帮助大家”拿下”这些纸老虎。

Part.1 State/Define

■ State/Define: 

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。我的天，终于不用背这么长的英文定义了。

Part.2 Compare

■ Compare: 

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’。看，是不是很容易就拿到分了。

Part.3 Describe

■ Describe：

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，我们需要强调两点点:”what happens”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。，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. 对比给出的答案，我们很容易拿到了full mark。

Part.4 Explain & Give

■ explain: 

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 explanation.

好了，这些就是A-level简答题中常出现的command words, 掌握也不难哦。所以，这些答题技巧你们都了解了吗？如果想要了解更多关于A-level考试及科目学习技巧，请关注锦秋A-level，锦秋A-Level项目针对不同学员的不同层次的学习需求，设置一站式计划、G5学霸计划和国际班互补计划三大课程体系，并且有针对性的制定课程计划和教学方式，开设的课程有数学、进阶数学、物理、化学、生物、经济学、会计学等，紧抓中国学生理科优势，进行课程组合化。配备海量国际背景的教师和专业助教团队，双管齐下，奠定每一位学员的之路。
