英文小作文：

標題：Disappearance and Loss

When something disappears, it no longer exists in our world. Whether it"s a person, a building, or even a memory, disappearance can bring about a sense of loss and emptiness.

Think of the times when a loved one moved away or a friend passed away. The world seems a little less complete without them there. Similarly, when a building is demolished or a memory fades, we feel a sense of loss and regret.

But disappearance can also bring about new opportunities and growth. When something disappears, it leaves space for something new to emerge. Maybe it"s a new building that replaces an old one, or a new memory that replaces an old one.

In the end, disappearance and loss are part of life, and we can"t avoid them completely. But we can learn to accept them and move forward with a positive attitude, knowing that new opportunities and growth lie ahead.
