为什么要加which,在这里起什么作用?

问题描述:

为什么要加which,在这里起什么作用?
a situation which forced them to make crucial decision about my education.把which删掉,这句话还可以成立吗?
整个句子是这样的:my parents discovered i was totally deaf,a situation which forced them to make crucial decision about my education

你的句子没打完整 应该在后面有真正的谓语
这里的which是指定语从句 后面的forced...修饰situation整个句子是这样的:my parents discovered i was totally deaf,a situation which forced them to make crucial decision about my educationmy parents discovered i was totally deaf中discover是谓语 后面引导宾语从句
后面定语从句修饰situation 可以看出从句缺主语 所以用which
