什么是宾语补足语

  • 要举例 再加说明为什么DONt copy
  • 宾语补足语有以下几类。1.由动词不定式充当。多数是带to的不定式,也有不带to的不定式。1).要求带to的不定式作宾语补足语的动词有tell,ask,invite,force,get,beg,allow,wish,want,like,prefer,intend,expect,encourage,advise,permit,order,warn,cause等。eg.I would prefer you not to change your plan.我宁愿你不要改变计划。They encouraged me to try again.他们鼓励我再次尝试。  2).某些动词如think,consider,believe,know,find等后面作宾语补足语的不定式常用to be + adj.的结构。eg.We believed him to be stupid.我们认为他很笨。He didn”t consider himself (to be) important.他并不认为自己重要。  3).某些动词如make,have,let,see,hear,watch,notice,feel等后作宾语补足语的不定式不带to。eg.He made us stay for tea.他使我们留下来吃茶点。Let me introduce you to Miss Li.让我介绍你和李小姐认识。Did you notice me leaveleaving the house你注意到我离开了(正在离开)那房子吗?4).变为被动语态时,不定式符号to必须保留。eg.People who won”t work should be made to work.必须要不愿工作的人工作。The middle-aged man was seen to enter the building.人们看见那中年男子走进大楼。  2.由-ing形式或过去分词充当。1).当宾语补足语的动作由作宾语的名词或代词发出时,宾语补足语用-ing形式。eg.He could hear his heart beating fast.他可以听见自己的心脏跳得很快。Do you smell something buring? 你闻到烧焦的气味了吗?  2).当宾语是宾语补足语发出的动作对象时,宾语补足语用过去分词形式。eg.Youd better have the desk painted.你最好请人把课桌漆一下。Ive never heard the song sung.我从未听见那首歌被人唱过。  3.由名词充当。某些动词call, name, make, elect, think, find, consider, appoint后接名词或代词作其语,再接名词作宾语补足语,补充说明宾语的身份。eg.He made her secretary.他挑选她当秘书。Her parents died, leaving her an orphan.她父母双亡,使她成了孤儿。They considered Paris the brain and heart of the country.他们把巴黎看作国家的大脑和心脏。 4.由形容词充当。某些动词如make,paint,keep,find,like,want等后接名词或代词作宾语,再接形容词作宾语补足语,补充说明宾语的状态、特征等。有的已构成……余下全文

非谓语动词的选择题怎么判断选择什么形式

  • 非谓语动词里面,除了一些固定规则,不定式和分词形式怎么判断选择,分词中现在分词的被动完成haveing been done和过去分词done有什么区别,如果可以请顺便说下to have been done
  • 我觉得你把问题复杂化了。没那么难,也不需要过多纠结。你只要把握两个关键点:时态和语态。首先非谓语动词包括分词(现在分词和过去分词)+不定时+动名词。具体问题具体分析,因为句子的时态并不是由他们决定。比如,Weather permitting, well go to the park.这个句子里就是用的permitting,句子可以改成If weather permits,we…. 这里的weather permitting做条件状语。因为是主动语态,所以用的是ing形式。再比如,All the work done, you can have a rest.可以改成AfterIf all the work is done, you can have a rest.因为是被动所以用过去分词,然后把be动词省去。把状语从句改成独立主格结构就是这样改写的。至于你说的having been done是现在分词完成式的被动语态,发生动作在主句之前。done则没有明确时间上的要求。to have been done就是将来会被做的事情。还有done可以做后置定语,having been done只有泛指人事物的时候可以做定语。否则一般不做定语。
