开场可能会用到的英语:
1. 稍正式些
It's great to be here with you today.
很高兴今天能来这里。
Thanks for having me today.
感谢邀请我。
2.稍随意：
Hi everyone, good morning·
直接问候早上好下午好之类的。
How's everyone doing?
电话会议中可能会发生一些状况，这种时候可以用到的英文表达：
You are on mute. 你静音啦
I cannot hear you. 听不到你说话
There's a lot of static on your end. 你那边杂音很多
Be out of sync 音画不同步
Poor connection! 信号太差
You've frozen. 卡住不动啦
不太明白别人说什么，请对方重述：
I really didn't quite understand what you meant by that, can you explain it to me again?
我真的不太明白你刚才所说的内容，可以再给我解释一次吗？
What i'm hearing or what I understood was…and then give them the chance to say their words again, maybe put it in another way.
你可以说我理解的意思是。。。再给别人一次机会去表述他们的意思，或许他们会换一种方式表达。
