How to translate "the Matter of Britain" into Chinese ? Is this a book or a story ?

Is there anyone here who can tell me about some Britain's history ? I know nothing about it, but I need to know some. About the Anglo-Saxon Period, or something else. Thank you very much.

I think we should make some changes in our daily life. One of the causations of extreme weather is the pollution. We should try decrease the life trash. Change plastic bags into the recycled bags, or turn down the water faucet in time... and so on.

I'm very worried about my spoken English now. I can only speak English at a low speed. Although in that condition, I would make a lot of grammar error. Another problem is that, I know some complex words, but when I practice my spoken English, I can only say some simple words. It makes me very worried and nervous. I don't know when I can speak like a native.

Hello everyone here. I wrote an essay yesterday to help me remember words. So it may be a little strange. Please correct it ! Be infinitely grateful ! On march 6th, our shareholders made a reference about our trademark. We were supposed to make it earlier. However because of the awful weather, we deferred for two days. Peter said that we need to dispel the stereotype about our trademark. For example, we usually put our slogan at margin of trademark. We conferred a lot. Tom gave us a reference from other company, then a novel idea came to my mind.

hello everyone, I have one question for people who would like to learn Cantonese. Why would your people like to learn Cantonese and not Mandarin ? It's really strange for me, I don't know what makes it is so popular and why. For Chinese people who living in north, (such as me) Cantonese is a difficult dialect to learn. BTW, i was wondering "strange for me" or "strange to me", which preposition is correct. Thank you guys !

How to remember words ? I'm always having trouble in remembering words. I forget them quickly !

Quelqu'un voudrais m'aider à apprendre le français？

I'm a native Chinese speaker, and also an English learner. If you want to practice Chinese, you can come with me. And if you can help me to practice my English, I'm also glad to hear that.
