在中考英语复习的过程中，完形填空一直是许多学生感到头疼的一部分。这部分题型不仅考察学生的词汇量和语法知识，还对学生的逻辑思维能力和上下文理解能力提出了较高的要求。为了帮助同学们更好地应对这一挑战，今天我们就来分享一组包含20个空的典型完形填空练习题。

完形填空通常会给出一段短文，其中部分单词被删除，要求考生根据上下文选择最合适的选项填入空白处。这类题目旨在测试考生是否能够准确把握文章的整体意义，并灵活运用所学的语言知识。因此，在做题时，除了注意单个句子的语法结构外，还需要关注段落之间的联系以及整篇文章的主题思想。

下面是一道模拟试题示例：

It was a cold winter morning, and the streets were covered with snow. John woke up early because he had an important exam that day. He quickly got dressed and made himself a cup of hot tea before leaving home. As he walked to school, he noticed how beautiful everything looked under the fresh blanket of white snow. Despite the freezing temperature, John felt excited about his upcoming test.

1. The first blank could be filled with “had” since it emphasizes the necessity or obligation for John to wake up early due to the exam.

2. For the second blank, “drank” fits well as it describes John’s action after preparing the tea.

3. The third blank might require “walked,” indicating John’s mode of transportation to school.

通过这样的练习，学生们不仅可以提高自己的语言技能，还能培养良好的阅读习惯和快速反应能力。希望上述练习能为正在准备中考的同学们提供一些有价值的参考！

请注意，以上内容仅为示例性质，实际考试中的题目可能会有所不同。建议大家多做真题练习，以确保充分备考。
