Question

more than needed 和 more than is needed 有什么区别吗
在大学英语教程第三册里 233页第四行 有more than is needed的说法

Answer 1

这两种说法都是存在的.
more than needed＝more than what is needed.即前者只是后者的省略形式.more than needed中needed过去分词起形容词用.
more than needed＝more than is needed,两者意思相当.
只是more than is needed还可以拆开成more...than is needed,这个时候more...than is needed＝more...than what is needed,即这个时候than后面的是个分句,needed是过去分词作表语.
而more than needed拆开的形式是:
1 more than sb.need/needed,即这里need成了实义动词,而不是过去分词做表语了.
2 more +名词＋than needed这里needed是过去分词做后置语了.
也就是说它们的结构略有不同.
