题目分析：

小题1:根据语境可知，家乡的这种变化是从以前就开始，一直持续到现在，并且变化的结果已经存在，故用本句应该用现在完成时。而表示近几年，用over the years。

小题2:“保持联系”是keep in touch with。根据语意可知，本句是一个特殊疑问句。故翻译成How do you usually keep in touch with your friends?

小题3:“去了”应是has gone to。“出差”是on business。故翻译成Lucy’s father has gone to Hong Kong on business .

小题4:“介意某人做某事吗？”是Do you mind sb’s doing sth？。 “关掉”是turn off。故翻译成Do you mind me/ my turning off the TV ?

小题5:“处理”是deal with。“怎样做某事”是how to do sth。故翻译成They don’t know how to deal with those old books.
