由time引导的定语从句引导词只能用when吗?
It's the third time _______ late this month.A.that you arrived B.when you arrived C.that you've arrived D.when you've arrive

答案

由time引导的定语从句引导词只能用when吗?
这个问题应该这样问：time后面跟的定语从句引导词只能用when吗?
不完全是这样.
请看例句：
1.He makes good use of the time ____ he can spare.
A.when B.that C.in that D.in which
2 There was ____ time ____ I hated to go to school.
A.a; that B.a; when C.the; that D.the; when 高考▲2004湖北
答案：1.B 2.B
第一句用that.因为that连词同时还在句子中充当宾语.即：he can spare （that = time）
第二句用when.因为when连词同时还在句子中充当时间状语.
这就是说,这个连词的选择,取决于该连词在定语从句中充当什么语法成分.
首先要判断从句中是否缺少宾语,（换句话说,就是从句是否需要一个宾语）,如果需要的话,优先选择连词 that （或which）.
如果从句中不缺宾语,就选when.
It's the third time _______ late this month.A.that you arrived B.when you arrived C.that you've arrived D.when you've arrive
在你提出的例句中,time后面跟的不是定语从句.它是一个固定用法：It's the ...time that ...(完成时态)
