现代英语中，Present Perfect Simple（现在完成时）和Present Perfect Progressive（现在完成进行时）是两种经常使用的时态。现在完成时通常用于表示一个动作从过去开始并且可能持续到现在，或刚刚结束但是对现在有影响的情况。例如，’I have finished my homework.’（我完成了我的家庭作业）。而现在完成进行时则侧重于表示动作的持续性，或重复发生，直至现在仍可能在进行。例如，’I have been reading this book for two hours.’（我已经读了这本书两个小时了）。在学习英语的过程中，掌握这两种时态的用法对于表达过去和现在之间的联系非常重要。
在进行以下练习时，你需要填入正确的动词形式来完成句子。这有助于加强你对现在完成时和现在完成进行时的理解和应用。请注意上下文，并根据每句中的提示来决定哪一种时态是正确的。这些练习旨在提高你的语法水平和英语运用能力。
