If some one say "Thank you" to you, what can we respond in English? except Not at all A: Thank you! B: Not at all. Any different ways there instead of using Not at all?

Reading is an interesting thing (any mistakes in my composition? like grammar or expression) 有热心人士吗？ I don't like reading books before, I usually watching drama on my smartphone in my spare time, but one day, I just think many things, and I have changed my mind, watching too much drama is just waste time and I can not learn anything from them. So I begin to find something meaningful to fill my spare time. There's many books in my office and I can borrow them for free, so I begin to try reading some books. And I have read 2 books and I can learn things from them, and there's many ideology in the books are really good. I begin to feel that reading is not a boring thing but an interesting thing. It's more meaningful than watching TV shows. I also borrow a new book named "To live a beautiful life" today! In addition, I also try to improve my English too. I don't want to be so lazy. I want to be more entreprenant.

Which one is correct? Group 1: Is it okay? Does it okay? Group 2: I am not sure if she will come to visit me this afternoon. I am not sure if she will come to visit me or not this afternoon.

Could you please let me know if there'e any mistakes on my text? 谢谢！ Today I get up at 7:30 o'clock, then I brush my teeth and wash my face and do some cooking. I usually cook something for lunch in the morning, I will put it into my lunchbox and than I will take it with me and walk to my office. There's a refrigerator in my office and I put my lunchbox into the refrigerator. We also have 3 microwave ovens too in the office. So I use one of them to heat my lunch. When I get off work, I usually ride the shared bike back to my dorm. There's a lot of shared bikes near my office. It's very convenient. I do not need to pay a deposit for riding shared bike because my credit is very good. I just got my driver's license for half a month, but my dorm is not far from the office, there's no need to drive a car to work. I prefer to walk or ride bicycle. They are environmental. That's all, thank you! Trying to write the first time
