Now do this put-the-text-back-together activity.
This is the text (if you need help).
A professor gave a two-hour online lecture but didn't realize he was on mute. Professor Wang did not know that in his online lecture, the microphone on his iPad was switched off. This meant that none of the students in his online class heard what he was talking about. His university switched his classes online to reduce the spread of COVID-19. His lecture started well but then his screen froze. The video came back but the mic was off. Professor Wang did not notice. One of his students says it might be because the professor used an iPad and not a computer.
Students tried many times to contact their professor in the lesson but could not get through to him. They waved their arms and called his phone. A video of the moment Mr Wang understood his mic was off has gone viral on the Internet. After he understood what happened, he looked shocked and stressed. He said he was upset because he wasted two hours of his students' time. He will redo the lecture at a different time so his students do not miss his class. One of his students posted on social media about the professor's accident. She wrote: "He teaches well. I feel bad for him."
Back to the online lecture lesson.
