你写完作业了吗？
EN： In theater and stage management, checking and counting inventory (like chairs for the audience) is a crucial part of 'front of house' preparations before a show begins. Using 'yet' in this context shows a practical focus on completing the pre-show checklist.
中文： 在劇場與舞台管理中，清點與確認物資（例如觀眾席的椅子）是演出開始前「前台」準備工作的關鍵部分。在此情境下使用「yet」展現了對完成演出前待辦清單的務實關注。
EN： The Present Perfect Tense ('have/has + past participle') is used here to show that an action was completed in the past, but its result is important to the present moment (the chairs are now ready). Note that while 'this morning' can sometimes require the simple past if the morning has passed, in spoken English, the present perfect is often used with 'this morning' if the speaker still considers it part of the current active period or to emphasize the completed state.
中文： 现在完成时（have/has + 过去分词）在这里用来表示一个在过去已完成，但其结果对现在很重要（椅子现在已经排好了）的动作。请注意，虽然如果早上已经过去，通常使用过去时，但在口语英语中，如果说话者仍将“今天早上”视为当前活跃时间的一部分，或为了强调完成的状态，经常与现在完成时连用。
I have already sent the email this morning.
我今天早上已经把电子邮件寄出去了。
EN： The pronoun 'all' can be used as a pre-determiner or post-pronoun to emphasize completeness. In the phrase 'arranged them all', 'all' modifies the object pronoun 'them', emphasizing that every single one of the items was arranged.
中文： 代词“all”可用作前置限定词或后置代词，以强调完整性。在“arranged them all”这个短语中，“all”修饰宾语代词“them”，强调每一个项目都已经被排列好了。
She invited them all to her birthday party.
她把他们都邀请到了她的生日派对上。
EN： The Present Perfect Tense (have/has + past participle) is used here to describe an action that has been completed in the very recent past, emphasizing the current state of completion.
中文： 现在完成时（have/has + 过去分词）在这里用来描述在不久前刚刚完成的动作，强调目前“已完成”的状态。
We have finished our homework, so we can play now.
我们已经写完作业了，所以现在可以玩了。
EN： 'Let's' is a contraction of 'let us', used to make suggestions or proposals to do something together. It is followed by the base form of the verb.
中文： “Let's”是“let us”的缩写，用来提出建议或提议大家一起做某事。后面接动词原形。
Let's go to the park this afternoon.
