1．It is generally considered that a taxi driver ought to be quite familiar ________ the streets in the city.
A．to B．with C．for D．in
答案 B [和familiar搭配的介词主要是to和with；be familiar to的意思是“为……所熟悉”；be familiar with的意思是“熟悉，通晓，精通”，根据题意“出租车司机要熟悉城市的街道”，选介词with符合题意。]
2．—I've made up my mind.
—________，there is no need for further discussion.
A．If any B．In that case
C．In case D．On that condition
答案 B [if any如果有的话；in that case如果那样的话；in case以防万一；没有on that condition结构。根据题意“如果那样的话，就没有必要再讨论了”，故选B。]
