Answer 1

问：what is the difference between "to do"and "doing"as a subject in a sentence

答："To do" and "doing" can both be used as the subject of a sentence, but they have different meanings."To do" is used to refer to an action that has not yet been done, but is going to be done in the future. For example:To go hiking is my plan for next weekend. (Here, "to go hiking" is the subject of the sentence, and it refers to an action that has not yet been done, but will be done in the future.)To finish this project on time is essential. (Here, "to finish this project on time" is the subject of the sentence, and it refers to an action that has not yet been done, but needs to be done in the future.)On the other hand, "doing" is used to refer to an action that is currently in progress or being done. For example:Doing homework is boring. (Here, "doing homework" is the subject of the sentence, and it refers to an action that is currently being done.)

答：In summary, "to do" refers to an action that will be done in the future, while "doing" refers to an action that is currently in progress or being done.

问：分析To finish the project in three weeks is impossible与Finishing the project in three weeks is the key to the success

问：这两个句子的不同

答：请等待片刻

答：这两个句子之间的主要区别在于它们的语法结构和表达方式。"To finish the project in three weeks is impossible" 是一个主语为 "To finish the project in three weeks" 的复合句，其中的主语为一个不定式短语。它表达的意思是完成项目需要三周的时间，但这个目标是不可能实现的。这个句子的重点在于不可能实现这个目标，强调的是困难和挑战。"Finishing the project in three weeks is the key to the success" 是一个主语为 "Finishing the project in three weeks" 的简单句，其中的主语为一个动名词短语。它表达的意思是在三周内完成项目是成功的关键。这个句子的重点在于成功需要在三周内完成这个项目，强调的是完成任务的重要性和关键性。因此，这两个句子在表达方式和语法结构上有明显的不同。第一个句子是一个否定句，强调了目标难以实现；而第二个句子则是一个肯定句，强调了完成任务的关键性和必要性。

答：当it作为形式主语时，to do表示的是尚未发生的动作，而doing表示的是正在进行的动作。
