I sent for a technician John isn’t familiar the computer software they use?
A. in case, with
B. in case, to
C. as if, for
D. so that, in

(答案→)A. in case, withB. in case, toC. as if, forD. so that, in解析：考察连词辨析和固定搭配。In case以防；as if似乎，好像；so that以至于； 固定搭配sb be familiar with sth某人熟悉某物；sth be familiar to sb 某物为某人所熟悉。句意：以防John对于他们使用的电脑软件不熟悉，我派人去请了一个技术人员。故A正确。
