同义句变换·利用时态改写

中考同义句改写中涉及的时态间的相互转换主要是针对一般过去时与现在完成时两种时态间的转换而言的，应特别注意非延续性动词的用法。如：

1. The film began 20 minutes ago.

The film has been _________ _________ 20 minutes.

【答案】on for。短暂动词begin，在此意为“(电影) 开始(放映、上演) ”，不能与延续时间状语连用，与延续性时间状语连用时，将begin 改成be up。has been提示时态是现在完成时态， “for+时间段” 表示“持续(一段时间) ”，常用在含有现在完成时态的句子里。

2. Sam’s grandfather died 10 years ago.

Sam’s grandfather has been _________ _________ 10 years.

【答案】dead for。短暂动词die，意为“死亡”，不能与延续性时间状语连用，与延续性时间状语连用时，将短暂动词die改为be dead。
