I tried to ______ Tom last night, but no one answered the phoneA.call upB.call onC.call offD.call for

A解析试题分析：句意：我昨天晚上试图给汤姆打电话，但是没有人接。call up打电话； call on号召； call off取消； call for需要。根据句意故选A。考点：考查动词短语辨析。点评：本题难度适中。动词短语是近几年高考的热点，不仅在单选还会出现在完形和短文改错中，主要考查对短语的意义和用法的掌握，同时要求考生正确理解语境。这里主要考查call与不同的介词或副词构成的短语。即学即练：The match was ______because of bad weather.A. called up B. called on C. called off D. called for解析：C。句意：由于天气不好比赛被取消了。
