两个都是引导宾语从句.第一句that I wasn't going to get much chance for promotion是realizing的宾语,第二句that I will be away from Boston next week是note的宾语.那为什么说I wasn't going to get much chance for promotion是主句Realizing是伴随状语其主语要和主句一致整个Realizing that I wasn't going to get much chance for promotion都是伴随状语，是以realizing为中心的现在分词短语， that I wasn't going to get much chance for promotion是realizing所带的宾语从句。
