From my perspective, you can use "angry with" + somebody, which means you feel angry because of the person. So, "-I'm angry with my sister" and "She's angry with me " are correct. When you use "angry at" + something, you mean you feel angry because of something. For example, I feel angry at being abandoned/ he feels angry at what he saw.

In Chinese, we don't have a prefix. Instead, we use another word(actually, a character, '重‘) to indicate the reoccurring status. In most of the conditions, you can use "重“ + a verb to indicate re-do something, or do something again. For example, 重做 （re-do), 重写（re-write), 重述（rephrase）.
