想问个关于it用法的问题
我想不通 In fact it is a hard job for the police to keep order in an important football match.这句前面的it 为什么不能换成this或者that
我想不通 In fact it is a hard job for the police to keep order in an important football match.这句前面的it 为什么不能换成this或者that
it指代后面的to keep order in an important football match,放在句首作形式主语,真正的主语是to keep order in an important football match,而为了防止主语过长,才用it代替.this和that没有it的这种功能.
