你可以这么考虑,I 是主语,think是动词,而后面的[drinking milk is good for our health]作为宾语从句来充当think的宾语,如果不好理解,你可以把[drinking……health]这句话用something来代替,这句话就成了 I think something.这样是不是更好理解?
其实这句话省略了一个引导词that,I think that drinking ……health.
这句话是对的,但是也可以去掉is,I think drinking milk good for health.
I 是主语,think 是动词,drinking milk当成宾语,而good for health可以当成宾语的补足语来理解.
