答题详解
focusing
详解：空格前为副词“initially”，空格后为介词短语“on videos...”，此处需要非谓语动词作状语，解释主语“Zhu”最初做视频时的关注点。主语“Zhu”与动词“focus”之间是主动关系，且表示伴随状态，故用现在分词形式“focusing”。
that
详解：本题考查“It was/is not until... that...”的强调句结构。句意为“直到2021年，她才……”。此句型为固定搭配，强调时间点“2021”，因此填入连接词“that”。
capturing
详解：分析句子结构，“she also imitated...”是主句，空格部分在逗号后，且无连词连接，因此应用非谓语动词作状语，表示伴随动作或补充说明。“capture”的逻辑主语是句子的主语“she”，两者为主动关系，故用现在分词“capturing”。
their
详解：本题考查并列结构中的代词一致性。空格处与前面的“their uncertainty”、“their helplessness”并列，共同作为“capturing”的宾语。根据上下文，这里指代的是“women from different time periods”在20世纪50年代作为女性工人的“自信”，因此需使用形容词性物主代词“their”。
saying
详解：逗号前后两部分之间没有连词，空格处需用非谓语动词作状语，表示伴随状态。“viewers”与“say”之间是主动关系，且“说”这个动作与“被感动”同时发生，故用现在分词“saying”。
is based
详解：本题考查动词时态、语态和主谓一致。句子主语“Her success”与动词“base”之间是被动关系（成功“被建立在”……之上），且全文主要时态为一般现在时，陈述客观事实，故用一般现在时的被动语态“is based”。
started
详解：根据上下文时间线索，“From then on”指代上文的“202年获得关注后”，动作发生在过去，且强调一个过去的时间点开始的改变，应用一般过去时“started”。
better
详解：本题考查副词比较级。句意为“理解过去能帮助我们_____活在当下”。根据逻辑，理解过去是为了“更好地”活在当下。且“good”修饰动词“live”需用副词形式“well”，其比较级为“better”。
