nought and zero I was told British people like using "zero", while Americans tend to use "nought". Is that the real case?

how to read "XXXL" ? I know "XL" read as "extra large", but what about "XXXL"? read "extra" three times? or maybe there's some other ways?

considering going to Britain this winter, what's its weather like?

First notebook entry: Introducing myself actually I'm an Englsih teahcer in China. I'm getting more and more awkward when my students asked me about some cultures or living habits of the Engtlish-speaking people since I'm really not a informed one in this case. So you know why I'm here now. Thank you so much in advance if you can help me in any way. And my other value of being Chinese can be used to help those Chinse Learners, I'm so happy while thinking of this.
