When I entered the classroom,I found all the students____ ready for class.
A.had seated B.seated C.had sat D.seating
请问A 为什么不对?

你要先分析主句的结构,I 是主语,found是谓语,all the students是宾语, 而后面的ready for class 是宾语补足语, 所以这个句子已经有完整的主谓宾很明显这个答案是只能做students的后置定语,这也是为什么不能选择A的原因,因为had seated 不能做定语,只能做谓语.
比如,I find this movie interesting.这就是典型的主语加谓语加宾语再加宾补.
你会选错是因为你以为find后面加的是宾语从句,但是如果加了宾语从句,句子会有一点点变化.
I found (that) all the students seated were ready for class.
而且,seat是个及物动词,要加宾语,不然就用 be seated.正确答案应该是 had been seated.
I found （that) all students had been seated ready for class.
