英语语法中定语从句

英语语法中定语从句的问题
1、Is this factory ______ the foreign visitors visited last week?
2、Is this the factory ______you once visited?
3、Is the factory ______you once visited?
A、where B、which C、the one D、that
答案1、C 2、B 3、C
能说出原因吗？

Answer 1

1 定语从句缺少先行词，This factory is ___ the foreign visitors visited... 同时先行词在定语从句中做visited的宾语（关系词可省略），填the one.
2 定语从句有先行词the factory了，只缺少关系代词，在从句中做visited的宾语，填which和that均可。
3 The factory is ____ you visited... 缺少先行词，定语从句却宾语，填the one.
——————————————————————————
The day he has looked forward to _____at last.
请注意he has looked forward to是定语从句，先行词是the day，在定语从句中做宾语(关系词被省略)，即
（他盼望的）那天，来了。
The day (that he has looked forward to) came at last.句子的主干是The day came at last.
懂了吗？

Answer 2

1.正常语序应该是This factory is the one (that) the foreign visitors visited last week. the one 做的是主句的表语，从句的宾语
2.正常语序为This is the factory that/which you once visited. that 和which 做的是visited的宾语，这题B和D应该是都对的
3。正常语序为The factory is the one(that)you once visited.原因同第一题

追问

哦，我还有一个问题：The day he has looked forward to _____at last.
A、coming B、came C、come D、comes
其实我选A，我认为look forward to doing词组中选择。但是答案为什么选D？
