劃分句子成分和結(jié)構(gòu),能幫助理解句子各部分的關(guān)系和句子意思：
1、
【W(wǎng)hen you go into the databases and electronic sauces時(shí)間狀語從句】 ,【you主語】【 have the option to display 謂語】【the abstracts賓語】 【on the computer screen介詞短語,地點(diǎn)狀語】,
【skimming those to decide whether or not you want to read the whole article should cut down some time.v-ing短語,作狀語】
2、skimming those to decide 【whether or not you want to read the whole article should cut down some time賓語從句】.
3、
whether or not you want to read the whole article should cut down some time 這種句子不是很正規(guī)=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）
祝你開心如意!
