Instructors sometimes include both synchronous and asynchronous sessions into the class.

教师有时在课堂上同时包含同步和异步课程。

One is synchronous learning – where the teacher and students are present together online at the same time.

一种是同步学习，即教师和学生同时在线。

But then they announced that it's going to be all synchronous and they're going to follow a bell schedule.

但后来他们宣布这将是同步的，他们将遵循钟时间表。

Online learning can be synchronous or asynchronous; synchronous learning is when you and your peers all attend class at the same time.

在线学习可以是同步的，也可以是不同步的；同步学习是指你和你的同龄人在同一时间上课。

Because so much of our work is synchronous, it's collaborative, there does need to be freedom within defined parameters.

因为我们的大部分工作是同步的，是协作的，所以在定义的参数范围内确实需要自由。

These can be different if two countries are not synchronous – occurring at the same rate, for example Britain and the United States.

如果两个国家不是同步的——以相同的频率存在，例如英国和美国，那电流可能会有所不同。

Interpersed with breakout groups or synchronous work and share documents, that's one of the tricks that I've been experimenting with.

穿插分组讨论或同步工作并共享文档，这是我一直在尝试的技巧之一。

So for example, I now offer my information in much smaller pieces, interspursed with breakout groups or synchronous work and shared documents.

例如，我现在以更小的片段提供我的信息，并穿插分组或同步工作和共享文档。

So the US and UK are not in the same synchronous area-not occurring together at the same time and rate, or in this case, frequency.

所以美国和英国不是同步地区——没有同时发生，这里指的是频率不同。

Standard frequency in the US is 60 hertz, actually I think in the US on the mainland, US main continent, there are three different synchronous areas.

美国的电流标准频率是60赫兹，实际上我认为在美国大陆有三个电流频率相同的不同地区。
