C解析试题分析：句意：技术工人的收入在增长，与此同时非技术工人却看见他们的收入下降。moreover并且；therefore因此；meanwhile期间，与此同时；otherwise要不然的话。根据句意故选C。考点：考查副词的用法。点评：本题难度适中。副词是近几年高考的热点，不仅在单选，还会在完形和短文改错中出现，主要考查它们的词义及用法，需要考生平时多记多练。这里必须弄懂句子的语意。即学即练：Jiuzhai Valley is far from big cities.__________ , it attracts people from all over the country for its beautiful scenery.
A. Still
B. Besides
C. Instead
D. Therefore解析：A。句意：still表示“仍然，还有”；besides表示“而且”，常构成递进关系；instead“相反，取而代之”；therefore“因此”，表示因果关系，故选A。
