the way用法

题目

the way用法
No one can answer the question _______ we can complete the task in time,do you know?— Yes,and this is because we don’t know the way _______ the scientist used last time
A:whether; which B:if; which
C:whether; in which D:if; in which
the way 后面不是跟 that in which 或者省略,为什么不选C

答案

第一空用whether

引导同位语从句,本位语（有些语法书上说是“先行词”）是the question, 

whether /if 都可译为 “是否”,但引导同位语从句时用whether 不用 if.

第二空用which,that或者省略

引导定语从句,先行词是 the way

什么情况下the way   后面跟 that , in which  或者省略?

   前提是定语从句不缺成分,完整的情况下才用.

如：I don't know the way that/in which/省略 she finished her housework. 

句中主(she)谓(finished)宾(her housework)都有,这时才用.

而题干中

the way _______ the scientist used last time ,

used 是及物动词,后面要接宾语,（last time 是时间状语）,并且先行词the way 指物,所以要用关系代词which 或者that 做used 的宾语,关系代词在这句话中作宾语时也可以省略.

所以答案是A

(提示：作定语从句的时候,一定要分析句子成分,缺不缺成分?才能决定用哪种关系词,不能生搬硬套)
