高中英语语法填空

We should try every effort 33 (prevent) violence happening at school for more and more students would drop out of school 34 their personal safety could not 35 (guarantee).
第34空 填because 为什么不行啊 求教

Answer 1

这是个复杂的从句for more and more students would drop out of school 34 their personal safety could not 35 (guarantee是We should try every effort 33 (prevent) violence happening （主句）的原因状语从句。而 34 their personal safety could not 35 (guarantee又是做more and more students would drop out of school 的状语从句，所以只能用 for /as because 不能引导状语从句，他是可以写个单独的句子

Answer 2

33 ( to prevent)
34 and
35 (be guaranteed
