如果写成这样追答…哦,对不起,我写的例子不对,应该是It is doctors' obligation to take certain precautions.
而如果想用obligatory呢。得这样:
It is obligatory to take certain precautions for doctors.
obligatory用来修饰行为,而不是事物所以也不能说sth is obligatory
再看一下下面的两个例句:希望有助于理解
The training is obligatory for all personnel.
This action movie includes the obligatory chase scenes.
