初三英语,问个问题

1.told a joke
2.has grown into

Tommy told a joke./Tommy had told a joke.

She has grown into a pretty lady when I saw her last week

1.told a joke
2.had grow into

1.-Why was Jamie laughing so happily?what happened?
-Tommy__told a joke _____(tell a joke)

2.when she was young,she is only a little girl
she__had grow into _____(grow into)a pretty lady when I saw her last week.

第一个空填telled a joke
第二个空填growen into

这两道题考察的都是过去完成时，在提示语中都有表示过去的过去，如1中的was laughing表示Jamie笑就已经是过去的时态，Tommy讲笑话的动作发生在Jamie laughing 之前，所以用过去完成时，为had told a joke，2中的when I saw her last week，是一种过去的时态，而grow into也在saw her last week之前，同样表示过去的过去，所以是had grown into
