Dear Joan, How have you been? I have received your letter. Thank you for the information and it helps me a lot. E-mails have helped us keep in touch with each other, and it’s a good way of communication. But now in China, WeChat is very popular. It is a cellphone application. It’s very easy to use. You can communicate with others as long as you have their WeChat ID. What’s more, you can also use WeChat for shopping and pay for bills and services. If you want to know more about WeChat, please call me. I’d like to help. Best wishes. Yours, Xu Hua 请根据上列短文,选择 "T" , "F" ________ 1) This is an e-mail from Joan to Xu Hua. ________ 2) Sending e-mails is not a good way of communication. ________3) WeChat is an application for computers. ________ 4) You need your friend’s WeChat ID to communicate with him on WeChat. ________5) We can only use WeChat for communication.
