解答 Do you think it (is) necessary to take measures to preserve Shanghai dialect?
本句是征求对方的意见,用一般现在时即可.
本句使用一般疑问句,其中含有结构动词think+it(形式宾语)+形容词(宾补),后面的不定式作真正的宾语;或者使用宾语从句it is necessary to take measures to preserve Shanghai dialect,其中it为形式主语,后面的不定式作真正的主语.take measures to do sth采取措施做某事.
点评 注意代词it的特殊用法:
it充当形式主语或形式宾语.在这种情况下,it没有具体的意义,只是帮助把真正的主语或宾语移到句子后部去.
1.it作形式主语,真正的主语可以是不定式、动名词,不定式和动名词有时可带自己的逻辑主语,真正的主语也可以是名词性从句,这个从句可以是that引导的,也可以由一个连接代词或连接副词引起的.如:
It is illegal to drive without a licence.无证驾驶是非法的.
It's a waste of time your talking to him.你和他谈纯属浪费时间.
2.it作形式宾语,构成复合宾语.在这一类的复合宾语中,由 it替代一个不定式、动名词或一个从句,放在句子的后部.能用这种结构作宾语的动词常见的有:think,find,consider,judge,feel,make,take等.如:
She found it difficult to hear what he said.她发现很难听清他说什么.
