这个是一个开头语，我不知道该怎么连了

kind 仁慈的，好心的
it is very kind of sb to do something 你做……太好了。是英语的一种习惯用法
例：It’s very kind of you to help us. 你太好了,能帮我们.
It’s kind of sb. to do sth. 致谢的一种表达方式.同义为:
It’s very nice of you to help us.

hear from “收到……的来信, 同意”, 与词组get a letter from sb 或receive a letter from sb. 同义.如:
I haven’t heard from him for a long time.我好长时间没收到他的来信了.
i have not heard from you for some times 意思就是我好长时间没收到你的信了

1 你做……太好了
2 我好久没收到你的信了
