该短语通常在句中作时间状语,位置灵活,可置于句首、句末,有时也可插入句中(较少见)。它常与一般将来时(will / be going to)、祈使句或表示决心、计划的表达连用,突出“从现在起的变化”。
From now on, I will wake up at 6 a.m. every day.
(从现在开始,我每天6点起床。)
From now on, please turn off the lights when you leave.
(从今以后,离开时请关灯。)
We need to be more careful with our expenses from now on.
(我们从今以后要更注意开支。)
I promise I won’t lie to you from now on.
(我保证从今以后不骗你。)
From now on, let’s practice English together every week.
(从现在起,我们每周一起练英语吧。)
From now on, don’t forget to lock the door.
(从今以后,别忘锁门。)
不要混淆 "from now on" 与 "from then on":
"from now on" 指“从现在起”(未来);
"from then on" 指“从那时起”(过去某一时间点之后的时间段)。
例:He made a mistake, and from then on, he was more cautious.(他犯了错,从那时起变得更谨慎。)
较正式的语境中,可替换为 henceforth(书面语,意为“从今以后”);口语中也可用 from this point on(从这一点开始)。
总结:"from now on" 是表达“未来起点”的常用短语,核心是连接“现在”与“未来的行动/改变”,用法简单且贴近日常对话。
