gobackto为固定短语，意思是“回到，追溯到”。

5．when　[考查副词的用法。

由句子结构可以判断这是一个定语从句，先行词是表示时间的inthemid－1980s，从句中缺少状语，因此填写关系副词when。

6．permitted　[考查定语从句关系副词的用法。

因为句中已有谓语动词was，故此处要用非谓语动词形式。

因permit与reporter为逻辑上的动宾关系，所以用过去分词。

7．introducing　[考查动名词的用法。

由句子结构可知，introduce作谓语动词include的宾语。

而Britishvisitors是introduce这一动作的承受者。

故用动名词形式。

8．its　[考查物主代词的用法。

根据空格后的名词及前文中的alivelythree－month－oldtwin可知要用形容词性物主代词。

9．days　[考查名词复数。

few用来修饰可数名词复数，故答案为days。

10．the　[考查固定搭配中冠词的用法。

由前文中的关键词twin,one可知这里考查one...theother...（一个……另一个……）的用法。

故答案为the。
