1.This is the museum we saw an exhibition the other day.
1.This is the museum we saw an exhibition the other day.
a.that b.which c.where d.in that
2.This museum is you visited the other day.
a.that b.which c.where d.the one
3.This is the museum you saw the other day.
a.that b.where c.in which d.in that
4.Have you ever been to Shanghai,Ileft ten years ago?
为什么用which而不是where?
非限制性定语从句逗号后面一定都是用which吗?
忘记说了，

1c 从句中 we 主语saw 谓语an exhibition 是宾语,the other day.是时间状语,先行词 the museum 表地点,从句中缺少地点状语,C
2d you visited the other day.是从句,缺少宾语,而选项中可做宾语的a.that b.which d.the one 但如若用A.B两项,则从句前无先行词,所以D,主句是
This museum is the one.
3a
you saw the other day.从句缺少宾语,先行词指物,that指代先行词在从句中做宾语
4因为left后面缺少的是宾语,所以用which而不是where

1c 2d 3a 4因为left后面缺少的是宾语而不是状语,所以用which而不是where
你看从句中缺少宾语就用which或that引导定语从句(此时非限制性定语从句用which);不缺宾语而缺状语就用where,when等.

定语从句其实很简单，你就看从句里面缺少主语或宾语不，当然如果从句动词是不及物动词也就不需要宾语，也就不缺少成分。那么如果缺少成分就选择关系代词who,whom,which,that,as,whose，不缺少就用关系副词where,when,why。
第一题，we saw an exhibition主谓宾完整，所以museum作地点状态还原是in the museum，选C。

定语从句其实很简单，你就看从句里面缺少主语或宾语不，当然如果从句动词是不及物动词也就不需要宾语，也就不缺少成分。那么如果缺少成分就选择关系代词who,whom,which,that,as,whose，不缺少就用关系副词where,when,why。
第一题，we saw an exhibition主谓宾完整，所以museum作地点状态还原是in the museum，选C。
第二题，这里其实不是让你选定语从句关系词，而是让你选先行词。因为本句没有先行词，所以能作先行词的只有the one，后面的you visited缺少宾语，实际上宾语就是the one，关系代词是省略了的that。
第三题，从句you saw，缺少宾语，所以选关系代词，只有that可以。
第四题，非限制性定语从句，从句是I left shanghai，上海作的是left的宾语。

1. C
定语从句we saw an exhibition the other day中缺少地点状语，所以用where，即：
(where) we saw an exhibition the other day
= (at/in which) we saw an exhibition the other day
= we saw an exhibition (a...

1. C
定语从句we saw an exhibition the other day中缺少地点状语，所以用where，即：
(where) we saw an exhibition the other day
= (at/in which) we saw an exhibition the other day
= we saw an exhibition (at/in which) the other day
= we saw an exhibition (at/in the museum) the other day
注：关系代词that不能放在介词之后，所以D错误。

2. D
如果选AB，则that/which后面是定语从句，但是主句This museum is不完整，排除；
如果选C，则C如果引导定语从句，同样主句不完整，如果引导表语从句，则where不能充当从句中visited的宾语，排除；
选D，则主句This museum is the one完整，且定语从句you visited the other day修饰先行词the one，因为the one在从句中充当visited的宾语，所以代替它的关系代词that可以省略。
即：the one (that) you visited the other day
= the museum (that) you visited the other day
而 (that) you visited the other day
= you visited (that) the other day
= you visited (the one) the other day
= you visited (the museum) the other day

3. A
定语从句you saw the other day中，谓语动词saw的后面缺少宾语（the museum），所以直接填入关系代词that。
that代替先行词the museum，在从句中充当saw的宾语。
而BC只能在定语从句中充当状语，而D明显错误（在定语从句中，关系代词that不能充当介词的宾语）。
即：(that) you saw the other day
= you saw (that) the other day
= you saw (the museum) the other day

4. which
关系代词which代替先行词Shanghai，在定语从句中充当left的宾语。
而where是关系副词，必须在定语从句中充当地点状语，所以不能使用。
即：(which) I left ten years ago
= I left (which) ten years ago
= I left (Shanghai) ten years ago

5. 非限制性定语从句的关系词不一定都是which，也可能是除了that/why之外所有的定语从句的关系词（不过考试中，非限制性定语从句使用which做关系代词的的确非常多见）。
到底用哪一个，需要根据句子情况具体分析。


注：楼主可以记住这两个诀窍：
1）把定语从句所修饰的先行词（只能是主句中某个名词/代词）放入定语从句中去，看它和从句其他成分如何连接。
如果直接可以相连（一般做从句的主语/宾语等），则定语从句使用关系代词；
如果不能直接相连（做从句的状语），则定语从句使用关系副词。
我上面的解答中有类似的推理过程，你可以细看一下，希望能对你有所帮助。
2）关系代词直接可以替换成先行词，而关系副词 = 介词 + 关系代词 = 介词 + 先行词
