英语四级词汇讲解丨归纳:pop

And scores of online discussion boards have popped up on which people discussnegative experiences tied to too much time on the Web.

英语四级译文:

网上突然出现了很多讨论区,专门讨论花太多时间上网的负面体验。

四级词汇讲解:

本句的主干是boards have popped up。on which引导的是以online discussion boards为先行词的定语从句,起补充说明作用,其中过去分词短语tied to too much time on the Web作negative experiences的后置定语,tied与negative experiences为被动关系。

pop up的意思是“突然出现,冒出来”。如:

After the rain, mushrooms seem to pop up overnight.

下过雨后,蘑菇似乎一夜之间就冒了出来。

tie...to...的意思是“使紧密结合”。如:

Our success is tied to you.我们是否成功和你紧密相关。

英语四级归纳:

过去分词短语作定语时,通常放在所修饰的词之后,实际上相当于一个定语从句。如:

※ These are problems left over by history.=These are problems thatlwhich axe left over byhistory.这些是历史遗留下来的问题。

※ I like the idea presented by my dad.=I like the idea that/which is presented by my dad.我喜欢爸爸提出的主意。

※ She is the first nurse trained by their country.=She is the first nurse that/who is trained bytheir country.她是她们国家自己培养的首 位护士。
