这句英文看不懂结构：whether or not you want to read the whole article should cut down some timewhen you go into the databases and electronic sauces,you have the option to display the abstracts on the computer screen,skimming those to decide whether or not you want to read the whole article should cut down some time.

要么就是skimming those to decide whether or not you want to read the whole article是主语，这样才能理解。whether 带的那部分是decide的宾语。

划分句子成分和结构,能帮助理解句子各部分的关系和句子意思：
1、
【When you go into the databases and electronic sauces时间状语从句】 ,【you主语】【 have the option to display 谓语】【the abstracts宾语】 【on the computer screen介词短语,地点状语】,
【skimming those to decide whether or not you want to read the whole article should cut down some time.v-ing短语,作状语】
2、skimming those to decide 【whether or not you want to read the whole article should cut down some time宾语从句】.
3、
whether or not you want to read the whole article should cut down some time 这种句子不是很正规=whether you want to read the whole article or not
=whether you want to read the whole article or you should cut down some time（for reading it）
祝你开心如意!
