英语词汇测试 – 你认识多少个单词？
English vocabulary test – how many words do you know?

这个测试评估你的**词汇理解能力**——你在阅读和听力中理解的词汇。这是一个衡量你在不同学科理解能力的重要指标，通常比你主动*使用*的词汇量大得多。该测试衡量对**词汇系列**（例如“limit”、“limited”、“limiting”）的理解，将它们算作一个单位。虽然基于包含 25,000 个词汇系列的数据库，但它并不能代表整个英语语言。通过复杂的统计方法和**计算机自适应测试**，只需较少的问题就能获得可靠的分数。结果可与超过 220,000 名其他测试者进行比较。如果你的初始结果显示可靠性较低，请**重新进行测试**，专注于准确识别你真正认识的词汇。

## MyVocab.info 词汇测试总结一个名为[myvocab.info](https://www.myvocab.info)的词汇测试链接在Hacker News上分享，引发了关于其方法和结果的讨论。该测试评估词汇量，据称范围可达超过一百万个已知的英语单词，并将分数与CEFR等级（欧洲共同语言参考标准）进行比较。用户报告的分数差异很大，有些人达到了超过典型母语者知识水平（23,300+词，C2等级）。另一些人质疑该测试的相关性，认为它侧重于鲜少在日常交流中使用的生僻词。讨论的中心是测试的有效性——衡量极端知识是否是一个有用的指标——以及英语作为一种不断发展的语言，能够 легко吸收外来词汇的本质。一些人捍卫该测试，指出其详细的“工作原理”页面，而另一些人则提倡基于使用的词汇评估。最终，许多人同意，庞大的词汇量并不一定能转化为实际的沟通能力。

What does the test measure exactly?

The test measures receptive vocabulary — the number of words you recognize in reading and listening. This reflects the range and depth of topics you can understand. Receptive vocabulary is usually several times larger than productive vocabulary, the words you actively use in speech or writing.

What counts as a word?

The test reports results in word families. For example: limit, limitation, limitations, limited, limiting, limitless, limitlessly, limits, and unlimited all count as one word family.

How many words are there in English?

In the test, the highest possible score is based on a database of 25,000 word families, but this is by no means a complete list.

How can the test work with only a few dozen questions?

This is the magic of advanced statistics and modern techniques of computerized adaptive testing. You can read more on innerworkings of the test.

Is there more information about how others score?

You can explore detailed results from more than 220,000 native and non-native speakers.

What should I do if my result reliability is low?

Take the test again. The more carefully you mark only the words you truly know, the more reliable your result will be.
