## Description
<section id="description">短语<a href="https://en.wikipedia.org/wiki/I before E except after C">“我在E之前，除了C之后”</a>是一个广为人知的助记符，它应该有助于拼写英语单词。使用提供的单词，检查短语的两个子句是否合理： <ol><li style="margin-bottom: 5px;"> <i>“我在E之前没有前面的C”。</i> </li><li> <i>“在我之前的C之前是C”。</i> </li></ol>如果两个子短语都是合理的，则原始短语可以说是合理的。编写一个接受单词的函数，并检查单词是否遵循此规则。如果该函数遵循规则，则该函数应返回true，否则返回false。 </section>
