I'm sure a lot of you've already known those rds, about and around.

我想在座大多人早就知道about和around。

Notice how the emphasis falls on the number, not the rd odd.

注意到该句话是放在数上，不是放在odd上。

But I still have " rd Joel Wolowitz" Left to go.

The PDT model was implemented to realize a web-based management information system for a digital orcha rd, and the digital system had been applied in Shandong Province, China since 2013.

PDT模型被应用于实现一个基于网络数果园管理信息系统，该系统自2013年起在中国山东省投入使用。

Now this rd odd is perhaps not as useful as around or about because we only use it for counting – we can't use it to talk about someone's age or to give an idea of the time.

但是odd没有about和around常用，因为我们只能用odd来表达数量上模糊概念，不能用它去形容人年龄以及表达时间概念。
