I don't know ... it looks about the same.The only difference is that it costs twice as much.Well, for twice as much money, it better be like night and day.When you say that two things are like night and day, that means they are completely different, or that one is far better than the other.Right!Here is another example.I was used to working on my old, slow computer, so when I bought a really fast new computer, it was like night and day.Exactly!So Li Hua, should we get some red potatoes, or the yellow potatoes?They don't taste similar at all!The difference is like night and day.You know Li Hua, there is one nice thing about the farmer's market.The employees at the supermarket aren't very friendly or helpful, but the farmers here are so nice!It's really like night and day.Well, I'm not going to eat my words just yet.I'll taste some of the fruit first, and then decide if it's worth the extra money.That's true.Your attitude is like night and day.

我不知道，它们长得一样。仅有的差别是它价格比其他高两倍。两倍价格好多钱呢，有着天壤之别。当你说两件事有天壤之别，就意味着它们完全不同，捉着一件事比另一件特别好。没错。有另一个例子。我习惯用我那台老旧的慢的电脑工作，所以当我买了一个快速的新电脑，它有着天壤之别。没错。所以李华，我们应该买红土豆还是黄土豆？它们味道差不多。这差别有天壤之别。你知道，李华，农民的集市有一点好的。超市的员工不友好也不帮忙，但是农民就很友好。这有着天壤之别。我还不打算认输。我先尝尝水果，然后决定是否值这些钱。没错。你的态度有着天壤之别。
