初一英语句型转换题The Ciass1,Grade7 students are planning a trip.(改为同

The students of Class 1,Grade 7 are planning a trip.

正确答案是：The students of Class 1,Grade 7 are planning a trip

(1)it is class1,grade7 students who are planning a trip.
(2)a trip is being planned by the class1,grade7 students.

答复如下：
The Class1,Grade7 students are preparing for a trip.
“plan”意为：计划、筹划、安排
这儿的“plan”相当于“prepare for”
“The Class1,Grade7 students ”不是这句话的主要结构，改不改无关紧要。
