首先,如果用what的话,what is required 是一个名词性从句(即,它的作用相当于一个名词),在句子中做主语,完整句子是这样的:What is required in the regulations “is” that you should not tell other people the password of your email account.注意到了吗?你需要加一个is在that前面.这句话等于:The requirement is that...
如果that前面有is,这道题就要选A了.可现在that前没有is,那么这句话就应该这样分析:
It is required that you should not tell other people the password of your email account.意思是什么?that后面的句子才是要求的具体内容,如果正常的语序应该这么说: "You should not tell other people the password of your email account" is required.引号里面是才是要求的具体内容,才是真正的主语,可这样说是不是给人非常头重脚轻的感觉?于是,it显神通的时候到了.用it代替整个主语放到前面,用that来把主语引导出来,这样就解决了整个问题.
楼主你懂了吗?
你不能把你email账户的密码告诉别人,这是必须的规定。it is required是一个完整的句子。that所引导的主从句正是it 所代表的内容,所以it就是形式主语。如果引导的句子代表的是前置短语的宾语regulations,那就不能用that,而要用what了。
如果用what的话 what is required ……is that前面部分整体做主语,中间加is 之后句子意思就对了
C It is 动词过去分词 翻译过来就是“据。。。”例如:it is said that the book is lost.据说那本书不见了。
