定语从句是由关系代词或关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,相当于形容词,所以又称为形容词性从句,一般紧跟在它所修饰的先行词后面。
(1)When television was first introduced, the extent to which it could affect human society could not have been foreseen.
人们发明电视的时候,并没能预见到它会对人类社会产生多大的影响。
(2)As is so often pointed out, knowledge is a two-edged weapon which can be used equally for good or evil.
正如人们常常指出的,知识是一把双刃剑,既可以用于造福,也同样可以用来为害。
定语从句按照关系代词的不同,会有不同的情况。
