You know I would suggest learning from history and realizing that none of these things are going to be error free.

你知道我会建议从历史中吸取教训并意识到这些事情都不会没有错误。

So if your essay is virtually error free and if you used a wide range of vocabulary in a formal tone, your lexical resource will have a good score.

如果你的文章几乎没有错误，如果你以正式的语气使用了广泛的词汇，你在词汇运用方面就会得高分。
