a boiled egg = a egg that was boiled 这一句就是一般过去时的被动语态
被动式就是指 be动词+过去分词 而be动词又能随着时态变化而变化 能体现时态
如一般现在时就是 is∕am∕are+done
一般过去式就是 was∕were+done
现在完成时 have∕has+been+done
过去完成时 had+been+done
desert是一个延续性动词,用现在完成时态表示的是对现在的影响,说明到现在为止车还停在那
而第一句的意思是鸡蛋被煮好了,没有强调对现在的影响.
这只是我自己的理解,不知道你能不能理解
我也是中学生,也在学 ,知道的就这些,不懂再问哦.
很乐意为你解答↖(^ω^)↗加油!
