英文小作文：

Half-Life of Time

Time flies like a bird, yet we often feel like it drags on endlessly. We live our lives in a cycle of days, weeks, months, and years, yet we often feel like we are stuck in the middle of it all, with no clear direction or sense of purpose. Half of our lives are spent waiting for the other half to come, but it never seems to arrive. We are always looking forward to the future, yet we often forget to appreciate the present moment.

Half of our lives are spent in a state of uncertainty, wondering what the future holds for us. But it is precisely this uncertainty that makes life exciting and full of possibility. We must embrace the unknown and learn to trust in our own abilities to navigate through the challenges that life throws at us. Half-life teaches us that life is not just about surviving, but about thriving and making the most of every moment that we have on this beautiful planet.
