有两点注意:
1.这是个并列句,反意问句在哪个分句,就应该和哪个分句的主谓语保持对应关系
这里,反意问句在后一分句 it is the third time he has been late
2.反意问句一般得和主句中的主谓语保持对应关系,（I think/suppose .+ 句子除外）,这里是 it is the third time

多谢你的回答想问下只有I think 此类用法例外吗还有没有别的

还有 I hope ...也是。其实，千万别死记一些规则什么的，关键是理解。比如说 I think he is a student, isn't he? 我肯定不会问don't I (我是这样想的吗？）。怎么样想，还要问别人？！：）

for 是并列连词，中文意思是“因为”，连接并列句，与 because, since, as 引导原因状语从句不同。但这还不是此题目的根本原因。
此题考查反意疑问句，空格部分要与全句的后半部分保持一致，即
it is the third time he has been late, _isn't it_?
原句中文意思：托米不是一个勤奋的学生，因为这是他第三次迟到...
