来英语大侠看看这句怎么翻译

Question

当我爬上楼梯来到教室时，我听到身后传来很大的声音。是我的英语老师叫我的名字。
1、When climing stairs to the classroom i heard a loud noise coming from behind。It`s was my E.T calling my name.
2、I hear loudly speaking when i climb the stairs comed to classroom in back。It`s that E.T call me name.
这两句有错吗，有错在不破坏句子本意下请帮忙指出并改正，并猜猜哪句是老师写的，嘿嘿

Answer 1

第一句表达正确，而且用了高档结构：状语从句中的省略，用动词-ing形式。这应该是老师所写。只是，你给的形式有敲打失误：It was,不是所呈现出的那样。
第二句则有失误，可以修改为：
2、 When I climbed up the stairs and came to the classroom, I heard a loud voice from behindIt was my E.T who called me name.
祝你开心如意！

Answer 2

1有点小错误，是老师写的吧，后面是it was，不是It`s was

2错的有点多。。
时态heard，climbed
翻译为声音，loudly speaking 是指说话声
非谓语用错，comed改为coming
in back用的很奇怪，还是behind好
后面还是It was，我认为最好改成It was my E.T who was calling my name

Answer 3

第一句是老师写的，第二句有错。
可改为 I heard someone speaking loudly from behind when I was climing the stairs。it was ET calling my name
