英语翻译
这是我们课本中一篇关于Helen Keller的文章.其中有两句是这样的
1:She would tap the letters into Helen's hand,then place in her hand the thing that the word described.(我感觉那个then 应该是the吧?)
2:Then began a teacher-pupil relationship and a friendship which lasted for nearly 50 year.(关系代词which应该用that吧?先行词有两个哎?)

不是,then然后
先行词即使有两个,但是都是指sth.就可以用which,又指人又指物用that
