“从一开始”常见的英文表达有 “from the very beginning”、“from the start” 或 “right from the outset” 。
from the very beginning：强调从事情最初的阶段就处于某种状态或进行某种行为，使用频率较高。例如：I knew from the very beginning that this project would be challenging.（我从一开始就知道这个项目会很有挑战性。）
from the start：语气较为简洁、直接，在日常交流和书面表达中都常用。例如：We were friends from the start.（我们从一开始就是朋友。）
right from the outset： “outset”本身就有“开始、开端”的意思，“right from the outset”更加强调从一开始就如此，带有一种较为正式或强调的意味。例如：Right from the outset, we had some differences of opinion.（从一开始，我们就有一些意见分歧。）
