副词的基本

结论：这篇文章详细介绍了副词在比较句型中的运用，包括原级比较、比较级和最高级的构成、以及与名词的比较。以下是改写后的部分段落：

副词的原级比较强调两者程度的相等，例如："Walking briskly for thirty minutes burns as many calories as running for fifteen minutes"。而在比较两个名词时，如果形容词或副词修饰了第一名词，应使用"so...as"结构，如"Thomas Jefferson's achievements as an architect rival his contributions as a politician"。

比较级通过"形容词比较级+than"表达一方优于另一方，如"Natural mica is cheaper to obtain than synthetic mica of a superior quality"。最高级则用于三者以上的比较，如"The most fearsome animal in the Western Hemisphere is the grizzly bear"。

副词的最高级用于强调程度，如"Of all economic problems, inflation remains the most significant in its daily impact"，而"Of all the activities, the criminal jurisdiction is the most familiar to the general public"。

理解并掌握这些副词的比较用法，可以帮助我们更准确地表达比较和等级关系，提升语言表达的精确度。
