"The younger one is my teacher."

Translation: 比较年轻的是我的老师。

[Aria_patriot]

I dont get it...

[DestinationVoid]

Could you ommit 比较 here?

[DestinationVoid]

Still not sure...

That's the difference between saying "the young one..." vs "the younger one...". The latter is what the English said, but it's a subtle difference in meaning

[roman2095]

Yes just 年轻的 is accepted

[Raimundo474613]

I think 我的老师是比较年轻的 should also be counted as correct.

[fO68fiJG]

This would imply that your teacher is relatively young, but not necessarily, that she was the younger of two given individuals.

[GanXingba]

Cant you also say "比较年轻的老师是我的." ?

It says this is wrong.

[DaveLommen]

That sounds more like: "The younger teacher is mine."

There are always different ways of saying the same thing, that's why i like to read these comments. I answered without the 比较. Just have to think about what they are looking for i guess. Here is another possibility: 年轻的那个是我的老师。

That's right, but usually it would be 那位 instead, since 那个 makes it sound less respectful, and teaching is traditionally a highly respected profession
