a-level物理常考知识点大揭秘(a-level物理怎么考)

A-level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,很多文字叙述题都可以迎刃而解。这类题中经常会出现一些关键词(command words),比如,‘Define’, ‘State’, ‘Compare’,‘Describe’等。小编整理了答题技巧的相关资讯,一起去看看吧。

  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。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. 对比给出的答案,我们很容易拿到了full mark。
