1、Such sentences do not always occur in thinking,and when they do they are merged with vague imagery and the hint of unconscious or subliminal activities going on just out of range.2、 Thinking, as it happens, is more like struggling, striving, or searching for something than it is like talking or reading. Words do play their part but they are rarely the only feature of thought.

“and when they do they”,as it happens這是什么句式？的意思是？going on just out of range的意思是？是短語嗎？do play their part的意思是？rarely，only 在該句中的意思是？

1 你斷句錯誤，and when they do為時間狀語從句，they是主句的主語。do為助動詞替代，替代前面occur in thinking.

2 as it happens在此為時間狀語從句，it指代thinking，當(dāng)思維發(fā)生時，

3 going on just out of range. 在思維范圍以外進(jìn)行著。為with復(fù)合結(jié)構(gòu)中的賓補(bǔ)。

4 rarely為半否定詞，幾乎不。only：唯一的，僅有些。

網(wǎng)友的英語水平不足以閱讀此類文章，這會打擊你學(xué)習(xí)英語的積極性。建議你換一個很容易的題材。
