{01} Steve was busy clearing the cups and dishes from the table ________ others were playing.
A.until
B.if
C.since
D.while
解析:D考察连词。While在…期间;后面要接延续性动词或者表示状态的动词。故D正确。Since意为自从,引导时间状语从句,从句使用一般过去时。If如果,until直到. 本题选D。 {02}—My son is addicted to computer games. He is hopeless, isn"t he? —Yes, ________ he is determined to give up and start all over.
