Nice to Meet You!*
My name is HIROKO. I want to speak English, but I am not good at speaking English.*
I want to overcame difficulties!
Thank_you to for reading my notebook.
*Another variation of this is: "Pleased to meet you!"
**Or you could just say: "I want to speak English, but I am not very good at it." {"it" can replace "speak(ing) English because it was already said earlier in the sentence.}
