The exchange was widely shared on Twitter, with Mr Musk wading in with some replies. What is the meaning of “wading in” here? Thank you!

In 2016 Toblerone courted controversy by changing the design of the chocolate bar to space out the distinctive triangular chunks in a bid to keep down costs. What is the meaning of “space out” here?

Minna Epps, director of the IUCN Ocean team, said the main issue was over the sharing of marine genetic resources. Why “over” is used in this sentence? What if I changed the sentence into “Minna Epps, director of the IUCN Ocean team, said the main issue was over the sharing of marine genetic resources.” Will it change the meaning?

I think the drawing is about the street in sham Shui Pó or Mongkok. I can tell you enjoy a life here. Hong Kong is a nice and interesting place. But I still think I should step out of the comfort zone and see the world more. Have posted loads of postcard from different part of the world. But never send one from where that represents me the most. So here it is. It’s really nice to have met you. Always appreciate your bright personality. See you later. Writing a postcard for my friend. Could you help me with this? Thank you

My student looks at his hands instead of the score every time he plays the piano. So I come up with a way to help him. This is how. How’s this paragraph?

This is how I torture my student. Forcing them to listen to my singing every single class. How is this two sentences?

Hi. I am leaving Hong Kong in April. I think I won’t be back for at least half a year. I think the situation in Hong Kong won’t get better soon. So I decided to visit my friends in Australia, Europe and Canada. Thank you for giving me the chance to teach Tom and I enjoy every moment with him. If you need any thing I can help, please feel free to ask. Like questions about piano or need accompaniment for Tom’s competition. I will do as much as I can to help. Since I will be leaving for a while, I think it’s better to refund the tuition fee to you. How can I write any better?
