it何时做模糊宾语何时做形式宾语

Answer 1

一、IT做形式宾语,通常和下列动词连用：consider,think,make,find,believe,count,declare,deem,fancy,feel,guess,imagine,judge,prove,see,show,suppose,understand,take等.例如：● We consider it our duty to support good leaders.● I think it best to get along well with others.● The new method makes it possible to complete the task faster.● Tom found it very embarrassing to be reminded of the long-standing debt.● Susan deemed it advisable to keep the matter secret.● We all feel it nice to be able to visit that distinguished university.● Who can prove it wrong to have a "make-money-quick" mentality?
这些IT句型的不定式动词短语前,也可用上"for"的片语,如：● Many Chinese here find it necessary for them to have a better command of Chinese.● They thought it desirable for English to be accurately used.● Such a plan makes it possible for older workers to be re-trained as useful staff.
二、IT在一些惯用语中出现：
Take...in turns; leave...to; owe...to; take...upon oneself to,如：● Can you do all together?I think you have to take it in turns.● I will leave it to you to assign the duties to the staff.● Paul owed it to Susan to explain the matter.● How can John take it upon himself to do all the chores?
除了代替不定式动词短语之外,IT也可以代替动名词与动名词短语成为句子的宾语.例如：●I do not consider it worthwhile spending too much time on telephone conversation.●She found it troublesome having to go through all the red tape.●Peggie deemed it tedious writing two or three drafts for an English composition.●Do you think it useful changing for the sake of changing?
