我们先来看一个例子:
◆ The mansion PAINTED RED is owned by the Lees.
上例中的PAINTED RED 就是一上必要的修饰语,因为如果没有PAINTED RED就会造成很多疑问。
我们再看一个例子:
◆ This mansion, RECENTLY PAINTED RED, is owned by the Lees.
上例中,RECENTLY PAINTED RED就是非必须的修饰。因为我们知道This 已经说明清楚所要讨论的mansion。
可以用标点符号修饰必须名词和非必须名词。对于非必须修饰可以用逗号将其中间隔开,而必须修饰则不用逗号。所以一个比较常见的标志就是which 和that ,当用which+逗号,常常用来进行一上说明,即非必须修饰,而直接用that 则进行必须修饰。
我们再来看一个例子:
◆ This mansion, WHICH HAS BEEN RECENTLY PAINTED RED, is owned by the Lees.
◆ The mansion THAT HAS BEEN PAINTED RED is owned by the Lees.
