题型:不详难度:来源:
The patients will have to wait all day ______ the doctor works faster.
A.ifB.unlessC.whetherD.that

答案
B
解析

试题分析:if是否,如果;unless除非,如果不;whether是否 ;that因为,以至于。句意:如果医生不工作快一点,病人们不得不等一整天。结合语境可知选B。
点评:连词在句子中主要起联系上下文的作用,他们之间的区别就是表示逻辑关系的不同,所以在解题时先要理解上下文含义,然后根据上下文逻辑关系选择合适的连词。连词的用法都比较多,语义之间还有交叉,熟记其基本应用规则,了解其区别,注意固定搭配对象,是做好此类题型的关键。
