as 和such that
The government made (such) a great effect (that) the whole nation could celebrate the spring festival happily
He bought (such) a dictionary (as) the teacher had
The teacher gave us (such) a difficult problem (as) none of us could solve (老师提示是要是solve后面有it 就要用that 这里的as.定语从句充当宾语)
后面两句完全看不懂啊 越具体越好 有类似的例句最好!
