问题描述：
____ is unknown to us all. A. When did she arrive B. When she arrived C. That when she arrived D. I
____ is unknown to us all.
A. When did she arrive B. When she arrived
C. That when she arrived D. In which she arrived
要有解释哦
答
B，
从题目中知道所缺句子成分为主语，能做主语的则为B，
A为问句形式，C中that不用，D则是in不应该放在句首。
答
B. When she arrived
作主语，要用陈述句语序
答
选B
这是主语从句 要用陈述语气
A 排除 不选C是因为特殊疑问句不要用that引到 直接用疑问词放在首位就行了
that 引倒陈述句
D arrive 表示到达是个不及物动词 不用介词
如果是
In which place she arrived 就可以选 arrive in 表示到达比较大的地方 which place 表示某地 which 一个词不行
