二．        不认识句子中的单词，但可以知道句子的意思。
读句子的第二个境界是，不认识单词也可以知道句子的意思。当我们看到一个句子中，有很多陌生的人名或者地名，我们仍然可以读懂句子，因为我们不认识的部分并不影响我们理解句子的意思。相似的，有很多融入专业知识的句子，尤其是科技类的阅读中，有些单词我们不认识，查字典可能查不到，有的即使知道中文可能也还是不知道它确切的意思，对待这样的句子，我们只看句子的大意，即什么，因为什么，或者导致什么，等等。忽略不认识的单词，我们仍然可以知道句子的意思。这类句子多见于物理，化学，天文，考古等方面的专业文章，注意我们读句子读的是句子的内容，而不是句子所放映出来了专业知识，我们读懂这样的句子还是很容易的。

三．        认识句子中的单词，但是不知道句子的意思。
读句子的三个境界就是，认识句子中所有的单词，但不知道句子的意思，这种句子可以称得上是难句中的难句，最让人头疼得句子。为什么会有这样的句子呢，第一，英语中有很多约定俗成的用法，也就是把几个词组合在一起从而有了新的意思，这些用法需要日常的积累，不知道这些俗语的意思自然很难知道句子的意思；第二，英语与中文不同的语序，表达方式，省略等导致句子很难读懂，有些是ETS人为的造出一些形势复杂的句子，导致虽然认识句子中的单词但不知道句子的意思；第三，语言与文化历史是很难分开的，所以缺乏对的文化历史背景的了解可能导致读不懂句子的意思，就像中国的成语，外国人很难品出其中的味道，体现在句子中就是有一定的借代，隐喻等等。对于这类句子，一方面要有对英语语言文化的一定了解，另一方面，需要拨云见日，看到复杂形式后面的简单的句子的意思。
