帮我编几段双人英语对话，口试用。

设计情景对话，要确定对话双方的身份。我简单“脑布”了一个场景，有关于一个同学上周感冒在家呆了一周，家里路由器不好使，无法上网，特高兴回学校的故事，可以用于同学之间课余闲谈，两人分别为 student a, student b。

student a: hi, student b (name, such as roger)! how are you going? good to see you here back on campus.

student b: oh, hello student a (such as kate)! i'm great! how are you then?

student a: i'm good! i heard you caught cold and therefore stayed at home for a week.

student b: yeah, true. it was so boring for me to just lie in my bed and do nothing.

student a: oh, pity! why didn't you surf the internet then?

student b: i couldn't, 'cause the router at home didn't work properly due to some technical issues.

student a: ....which means you cannot surf the internet at all?

student b: i have to say, no. that's why i am eager to be back in class! it's so relieved to see you guys again!

student a: yeah, and you can use the free wifi on campus again.

student b: of course!

我不清楚这个小对话对你来说够不够两分钟，因为我本人语速很快，说这个可能只有几十秒。如果你是用于类似雅思口语练习的话，这段我自己原创脑补的小对话可以帮助你拿到一个不错的分数。如果你口语发音足够好的话，会相应更加分的。

希望对你有所帮助哦～
