The students of Senior 3 are now under great pressure for it will be just one year ______ they take the Entrance Examination. A．since B．after C．before D．when

Answer 1

C

试题分析：句意,上文,高三的学生现在都很大压力,下文，因为只有不到一年的时间就要参加高考了。考查句型it was/will be +一段时间+before+clause ,没过多久。。。就 ，从句常用一般现在时或一般过去时。since意思是自从.常和完成时态连用，after在。。。之后，when当。。。时候。故选C. 点评：解答此类题型首先要确定上下文关系,根据前后文关系确定适当连词.还要记住一些常用的句型结构：it was/will be +一段时间+before+clause ,没过多久。。。就，从句常用一般现在时或一般过去时。
