但是还是没有很暸也
过去分词句型是S+had +过去分词
为什么要写成
The house my parents
had been planning to sell was at last sold last month.
写成
The house my parents
had planned to sell was at last sold last month.
不是更符合过去分词的句型吗
还有
写成The house my parents
had been planning to sell was at last sold last month. 是可以的
那么依据过去分词的句型:had+过去分词写成The house my parents
had been planned to sell was at last sold last month.为什么不行
