"I ate dinner together with my aunt yesterday."

Translation: 昨天我和我阿姨一起吃晚饭。

[JChien6953]

should be 吃了 since it says "ate"

Maybe because 昨天 is included, the 了 would be redundant?

[RemieSmith]

Pretty sure this is the answer. It seems to be optional unless leaving it out would be ambiguous

[Patrick_Dark]

It'd be nice if these "individual A with individual B" exercises accepted "跟" and not just "和" in answers especially since "跟" was covered in a prior lesson. "我昨天跟我阿姨一起吃了晚飯。" and "昨天我跟我阿姨一起吃了晚飯。" are both rejected.

"昨天我和我阿姨一起吃了晚餐。" was rejected as well because "了" is apparently forbidden. I was pleasantly surprised to see that "昨天我和我阿姨一起吃晚餐。" (with "了" removed) with the alternative word for dinner was accepted, at least.

yeah this app is stubborn even i am a native speaker are feel weired

[Karoliina765050]

I've also come here to wonder whether the 了 was not needed.

[z4096]

Optional, since it's implied by 昨天

[RobinThor]

If it is optional 昨天我和我阿姨一起吃了晚饭 should be accepted.

Can you say 我昨天跟阿姨吃晚饭?

[JustinKim869356]

太殘忍了吧

[tabthesciencebab]

I thought I learned together with someone as "我和__(verb)在一起". Can anyone tell me if its right?

[cafe_disco]

I'm not a native speaker, but that doesn't sound right. From the Chinese that I've read/heard, 一起 comes before the verb, not after. I think a more correct template would be: 我和(person)一起(verb). For example, 我和我爸爸一起吃早饭 would be "I eat breakfast with my dad."

[Gabrielle145359]

I think you are combining two structures.
"我和someone一起verb" means "Someone and I verb together."
"我和someone在一起” means "Someone and I are together" (spending time together in the same place.)
