沧海一粟

    Bucket是“水桶”，a drop in the bucket是什么意思呢？请看对话：

    A: Let’s have dinner together today. A friend recommended a very good restaurant, and I haven’t had time to try it yet.

    B: I’m not sure when I can get off the hook. I did a lot of work this morning, but I have so much to do it was just a drop in the bucket. I’ll take a rain check.

    Note: A drop in the bucket means “a small, and thereby relatively insignificant, part of a whole.” The idiom may have come from the Bible, where the original text says: “Behold, the nations are as a drop of a bucket, and are counted as the small dust of the balance.” A similar saying is “a drop in the ocean,” which appeared later than “a drop in the bucket.”
