"你上个周末做了什么？"

Translation: What did you do last weekend?

[NickTimms5]

What is the purpose of the 了in this sentence?

[kaku1911]

It represents a completed action - so "doing" becomes "did".

[WillowsofXihu]

Changing 做 to past tense (do -> did)

[JoaquinMoy2]

To make the past verb tense

[squiggy2]

It is to show past tense. It also can show a change of state in present tense, but in this sentence it turns 'do' into 'did do'

[KeroppiDaFrog]

It's for passtense

[RindyLong]

Why do you put 了 after 做 here but in the previous example you don't put 了 after 在? It is obvious from saying last weekend (上个周末) that this is a completed action in the past, so why is 了 required here but not after 在?

[GiuseppeLucci]

我喝了好酒

[JessicaPer136520]

The audio for 了 is wrong in about 1/2 of the cases, sounds like "liao" rather than "le" and other times, sounds right...very frustrating, they really should fix it.

[tolunayo]

了 has two spellings. le is the correct one here. liǎo is the alternate spelling with different meanings.

[Clara604861]

Then their automatic voice generator for the female voice intonated the other pronunciation (liǎo instead of le) and they wrongly inserted that audio here.

What's the difference between 昨 and 上个？

[Gabriel873750]

昨，as in 昨天，is yesterday.
While 上个 means last in a context like last week, last month, etc...

[Eugene863168]

I think its easier to say 干什么 instead of 做了什么

[l.u.cas]

If you were to use a word that uses a different measure word than 个, would you put that measure word after 上 instead?

[Andrew-Lin]

Do you mean, say, "last book"? It would be OK to say "上一本书."
"上本书," however, sounds a bit weird.

[Anderson__Campos]

No, you cant, it depends on the word, 个is the overall measure word

[Dejo]

"What did you do on the weekend" implies the last weekend, but I got it marked wrong.

[SmithUA01]

where is "last" in the chinese sentence, and why is "what did you do at the weekend" wrong?

[Anderson__Campos]

上 means last/past in this case

[Ann336867]

also at the weekend doesn't make sense, it should be during the weekend.

[JMac312]

I believe 了 is used to denote past tense

[Andrew-Lin]

Not past tense, but perfect aspect. I myself think that when to use "了" can be a profound "art" for foreigners so please ask experts for details :p

[Ann336867]

It can be both I think, adding le can change chi to either ate or eaten.

[Nathan903064]

Last weekend what did you do is incorrect?

[zhouhuanyue]

yes, you are wrong

[Ann336867]

It's not correct english, it would make sense if you changed it to What did you do last weekend?

[nrh839436]

What were you doing last weekend

[nrh839436]

Incorrect or not?

[MackBarcel]

Why is the other zuo an incorrect choice?

[SebastianB482298]

Im not english speaking native but isnt: What did you do THE last weekend. Also a right answer?

[JordanKnowz]

Why is the pronunciation of "了" "liao" instead of "le"???

[RindyLong]

I PUT WEEK INSTEAD OF WEEKEND
AHHHHHHHHH!H!H!HH!!H!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
so annoying!
