Present Perfect Progressive tense（现在完成进行时）是英语语法中的一种时态，它用于表示从过去某一时间点开始，持续到现在并可能继续进行的动作或状态。这种时态通常会和表示时间的状语连用，如“for two hours”（两个小时了）、“since last year”（从去年起）等等。在构造这种时态的句子时，我们会使用“have/has been”加上动词的现在分词（ing形式）。现在完成进行时的使用相对复杂，需要学习者细致理解它与其他时态的区别以及在特定语境下的正确应用。
通过练习现在完成进行时的句子填空，学习者可以加深对这一时态的理解并掌握其构造方式。以下的练习将给出部分已构造好的现在完成进行时的句子，并留出一个空白处，学习者需要根据提示词填入正确的形式，以完成句子的意义。这样的训练有助于学习者在实际交流中更自如地运用现在完成进行时，更精确地表达动作的持续性和未完成性。
