Capacitance, or the ability to store electric charge, is one of the most common characteristics of electronic circuits.
由同位语我们很快猜出生词capacitance词义--电容量。需要注意的是：同位语前还常有or, similarly, that is to say, in other words, namely, or other say. 等副词或短语出现。
定语从句：
Krabacber suffers from SAD, which is short for seasonal affective disorder, a syndrome characterized by severe seasonal mood swings.
根据生词SAD后面定语从句which is short for seasonal affective disorder和同位 语a syndrome characterized by severe seasonal mood swings, 我们可以推断出SAD含义，即"季节性情绪紊乱症"。
3. 根据举例猜测词义恰当的举例能够提供猜测生词的重要线索
例如：
The consequences of epochal events such as wars and great scientific discoveries are not confined to a small geographical area as they were in the past.
