It is time the authorities concerned took proper steps to solve the traffic problems.有语法错误吗“该是……的时候了”句型,请问这句子正确吗?为什么“concerned”后面的“take”还要用过去分词形式?

问题描述:

It is time the authorities concerned took proper steps to solve the traffic problems.有语法错误吗
“该是……的时候了”句型,请问这句子正确吗?为什么“concerned”后面的“take”还要用过去分词形式?

有错误。
应该为 It is time the authorities concerned to take proper steps to solve the traffic problems.
到了相关部门采取必要措施解决交通问题的时候了。
took 改为 to take,去采取。

“该是……的时候了”
It is time sb. done sth.结构

语法完全正确
it is time 后面的句子要用虚拟的,前面用一般现在时态,后面就用过去took,或者should take
到了有关当局采取有效措施解决交通问题的时候了.
concerned ...这里是过去分词短语做定语,修饰前面的authorities

感觉少了个be动词
concerned前面是不是应该有个are
希望能帮到你
