Answer

1.haven’ttravelled

2.Havestarted,yet

3.don’tthinkshould

4.got to

5.Wherehas

【解析】

1.此处的助动词是have，故改为否定句，用助动词haven’t。故此处为：(1). haven’t (2). travelled。

2.此处助动词是have，变为一般疑问句，把助动词have提前位于句首。already用于肯定句，yet用于一般疑问句或否定句。故此处为(1). Have (2). started,yet。

3.think后面的宾语从句的否定形式，前置位于think前，主语I是非第三人称单数形式，修饰实义动词think，故用助动词don’t。故为：(1). don’t (2). think (3). should 。

4.reach=get to到达，根据yesterday可知此处用一般过去时，故为(1). got (2). to 。

5.对Hong Kong提问，是对地点提问，故用疑问词where。故为(1). Where (2). has。
