This is one of four criteria on which you will be tested, look for the other three criteria in other videos.
这是雅思口语考试的四个评分标准之一。我们会在其他视频中分别介绍另外三项评分标准。
Lexical resource focuses on the range of vocabulary a candidate uses.
“词汇多样性”着重考查考生所使用词汇的广泛性。
The wider the range, the better you will score.
使用的词汇越广泛，越多样，你的分数越高。
You will need to understand these factors to score well on the test.
要在考试中展现词汇多样性，你需要注意以下几点。
The ability to use vocabulary effectively, including the right collocation, that is words naturally used together.
首先是有效使用词汇的能力，这包括正确使用词语搭配，也就是通常用在一起的词语。
For instance, lion's roar, lions do not shout.
例如，lion's roar（狮吼）, 而不是 lion's shout。
Alternatively, we make a phone call, we do not do a phone call.
再例如，我们说“make a phone call （打电话）”，而不是“do a phone call”。
And awareness of connotation.
其次是对于词义内涵的认识。
This refers to the positive, neutral or negative associations some words have.
某些词语可能含有褒义、贬义或中性的深层意义。
For example, laid-back, positive; inactive, neutral: lazy, negative.
例如，laid-back褒义；inactive 中性；lazy 贬义。
Slim, thin, skinny.
再例如slim褒义；thin中性；skinny贬义。
The use of less common vocabulary or expressions.
第三点是使用并不常见的词语或表达方式。
Many candidates memorize impressive lists of vocabulary but often end up using them in the wrong way,
许多考生背诵很长很长的单词表，令人惊叹，但却无法正确地在交流中使用这些词汇，
because they haven't understood them properly.
因为他们并没有真正理解其中的意思。
