insist作反复说、一定要、坚决要求解,可以是及物动词,也可以是不及物动词。

一、 作不及物动词用时,后跟on或upon引起的短语

1) insist on / upon +动名词(或动名词的复合结构) She insisted on seeing the manager as soon as possible.

He insisted on a second message being sent (不用to be sent) to them.

We insisted upon his staying with us for another week.

2) insist on/ upon+名词 They insisted on a definite answer.

I insisted on a replacement for the broken part on my bike.

Our English teacher insists upon the importance of the correct pronunciation.

注意: insist on (doing) sth. , stick to (doing) sth.与persist in (doing) sth.的区别:

这三个短语都有坚持的意思,但侧重点不同。

insist on (doing) sth.是坚持某种做法、意见、主张。

如: They insisted on leaving that day. 他们坚持要在那天走。

stick to (doing ) sth. 是坚持原则、计划、诺言、决定、真理、路线等。如:

He always sticks to his promise / his plan. 他总是坚守自己的诺言/计划。

如果表示继续努力从事于某项工作,stick to后也可接动名词。

如: If you stick to practising English, you'll make great progress. 要是你每天坚持练习英语,就会取得很大进步。

而persist in (doing )sth.指不作任何改变地坚持某事,可能是一件好事,也可能是一件坏事。常包含固执己见的意思,但也可指意志的坚定。如:

She persists in her opinion. He persists in his sparetime studies.

She persisted in wearing that old-fashioned dress.

The old woman persists in taking half an hour's exercise every day. (表示意志的坚定,不用insist on来代替)

二、 insist 作及物动词的用法 insist的此种用法只能接从句作宾语。

1)insist作坚决要求、一定要,其宾语从句常用与将来事实相反的虚拟语气,即should+动词原形,其中should可以省略。如:

Her father insists that she (should) learn music after she leaves school. 。如:

Alice insisted that she had done nothing wrong.

3) insist that...有时与insist on / upon互换。如上面1)、2)中的两个例句可分别改写为:

Her father insists on her learning music after she leaves school.

Alice insisted on her having done nothing wrong.
