The incomes of skilled workers went up. ______, unskilled workers saw their earnings fall.
A．Moreover
B．Therefore
C．Meanwhile
D．Otherwise
答案
C
考查副词词义辨析。根据句意skilled workers表示"熟练工人"和unskilled workers 表示"不熟练工人"两者情况的对比。Moreover“再者，加之，此外，而且”；therefore“因此，所以”；otherwise“否则，要不然”； meanwhile“在此期间，同时”，符合句意，故选C.
