What is the benchmark? 什么是基准？

　　It is a point used in the survey. 它是调查中使用的要点。

　　Usual, numbers used as benchmarks are five, ten, fifteen, twenty and so on. 通常，作为基准的数字是5、10、15、20等等。

　　Why is a benchmark important? 为什么基准很重要？

　　Without a benchmark, we cannot compare anything. 没有基准，我们就无法比较任何东西。

　　For example, let's say you ate strawberries. 例如，我们假设你吃草莓。

　　Also you recorded how many strawberry you ate. 你还记录了你吃了多少草莓。

　　Did you eat a lot, or did you eat only a few? 你吃得多还是吃得少？

　　If there is no benchmark, you will not know if you ate many or few. 如果没有基准，你就不知道你吃得多还是少。

　　But if more than five strawberries are many, you can say I ate six strawberries, so I had many strawberries. 但如果超过五颗算多的话，你可以说我吃了六颗，所以我吃了很多草莓。

　　The benchmark is five strawberries. 这个基准就是五颗草莓。
