In April 2017, two giant pandas from China arrived at a zoo in the Netherlands. There, they were welcomed to the Chinese-style compound where they were to live. On 30 May, after the preparations were complete, the day finally came when the pandas met their fans for the first time. People were excited – the zoo is the only place in the country where it is possible to see pandas. In fact, the last time there were pandas in the Netherlands was in 1987. And of course, the main reason why they were so excited is that pandas are just so cute!

That was the time when he arrived.
Do you still remember the time that/which we spent together
This is the reason why/for which he went.
The reason that/which he gave us was quite reasonable.
四. 指点迷津：
when, where, why与that, which的区分
指时间，地点或原因的先行词在定语从句中作状语时用when，where或why；而作主语或宾语时，要用which或that。
用关系副词when, where, why引导定语从句的两个前提条件是:
(1) ________________________________
(2) ___________________________________________。
先行词为表时间、地点和原因的名词
when, where, why在其引导的定语从句中作状语
This is the place ______ he works.
This is the place __________ we visited last year.
That was the time ______ he arrived.
Do you still remember the time __________ we spent together
This is the reason _______________ he went.
The reason __________ he gave us was quite reasonable.

which/that
when
that/which
why/ for which

怎样判定关系词是否作状语
①不及物动词或及物动词后有宾语要求用关系副词作状语
②及物动词后面无宾语(即缺宾语）或定语从句缺主语，就必须要用关系代词
Vi: stay, work, live, arrive, study(学习)
Vt: spend, visit, study(研究)，drop in(顺便拜访)
五. 总结做题方法
Step 1:
Step 2：
Step 3:
找先行词确定其性质（人/物）
将先行词代入从句中看做何成分
确定关系代词 /关系副词
抽象地点名词
先行词为表地点含义的抽象名词：situation, case, position, point 等，如从句中缺少状语时，用where引导定于从句。
