在学习英语中，掌握时态对于能够准确地表达过去发生的事情或至今已经完成的事情尤为重要。本文的练习将专注于两种常用时态：一种是表示过去某个特定时刻或时间段内发生的动作或状态的简单过去时（Simple Past），另一种则是强调过去发生的动作对现在造成的影响或结果的现在完成时（Present Perfect）。通过这两种时态的对比练习，学习者可以更清晰地理解它们的用法及差异。
这些练习将帮助学生们巩固对这两种时态的理解并学会如何在实际语境中恰当使用它们。每个句子中将有一个空格，学生需要根据给出的提示词填入正确的动词形式。通过填空练习，学生们能够在上下文中练习并应用这些时态，从而提高他们使用英语的流畅度和准确性。
