如果生词是句子或段落所解释的定义,理解句子或段落本身就是推断词义。 例如...雅思阅读猜词之根据举例 恰当的举例能够提供猜测生词的重要线索。 下面是小编给大家带来的雅思阅读根据定义进行生词猜测，希望能帮到大家!
例如： anthropology is the scientific study of man. 由定义可知，anthropology就是“研究人类的科学”。
In slang the term "jam" constitutes a state of being in which a person finds himself or herself in a difficult situation. 同样，从上下文的定义可知jam一词在俚语中的意思是“困境”。 定义句的谓语动词多为：be, mean, deal with, be considered, to be, refer to, be called, be known as, define, represent, signify, constitute等。
同位语 Semantics, the study of the meaning of words, is necessary if you are to speak and read intelligently.
Capacitance, or the ability to store electric charge, is one of the most common characteristics of electronic circuits.
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 i. e. 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”。
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. 句中“战争”和“重大科学发现”是生词的实例，通过它们我们可以猜出epochal的大致词义“重要的”，这与其确切含义“划时代的”十分接近。
The principle of float glass is unchanged since the 1950s. However, the product has changed dramatically, from a single thickness of 6.8 mm to a range from sub-millimeter to 25mm, from a ribbon frequently marred by inclusions and bubbles to almost optical perfection. To ensure the highest quality, inspection takes place at every stage. Occasionally, a bubble is not removed during refining, a sand grain refuses to melt, a tremor in the tin puts ripples into the glass ribbon. Automated on-line inspection does two things. Firstly, it reveals process faults upstream that can be corrected. Inspection technology allows more than 100 million measurements a second to be made across the ribbon, locating flaws the unaided eye would be unable to see. Secondly, it enables computers downstream to steer cutters around flaws.
Dramatical change of the product:
1.thickness: a single thickness of 6.8 mm <> a range from sub-millimeter to 25mm
2.quality: a ribbon frequently marred by inclusions and bubbles<> almost optical perfection
3.inspection: automated on-line inspection
