我安装的大学英语四级怎么读的部分没有声音啊？

I graduated from university several years ago and now I am a university English teacher. Last week my department sent me to the airport to meet a visiting American professor. When I met him at the airport he had two heavy suitcases and some smaller bags. He was an older man, in his sixties I think, and we couldn’t find a luggage cart, so I wanted to help him with his luggage. Several times I offered to take one of the heavy suitcases for him, and each time he insisted that he could carry the suitcases himself. However, he seemed to be having some difficulty moving both of the suitcases, so at one point when we stopped and he put the suitcases down, I just picked one up. When I picked up the suitcases he said “I can handle these myself“, but I thought he was just being polite so I went off toward the van with the suitcase. However, when we got to the van he seemed annoyed with me, and he hardly spoke at all to me the whole way to our school. Why did he get upset with me? Was it wrong to try to help him with his luggage?
