问题描述:
I don't know ----- there is any danger in this type of plane.填if 还是that.
我明天就要考试,还有能讲一下I don 't know 后跟that 和if的区别吗,我们老师讲的云里雾里的
答
if那这句话是什么意思,不能用that吗不能,如果用that 的话就要吧标点符号改一下了能说清楚一点吗i dont know if there is any danger in this type of plane, 我不知道这种飞机有任何危险。 i dont know that there is any danger in this type of plane! 可我以前不知道这些飞机存在危险! 而且如果要用that的话也要把is改成was
