"上星期他感冒了。"

Translation: He caught a cold last week.

[stevebeaker]

For the audio, 她 should be accepted as well, not just 他。

[Hedwigechouette]

"he had a cold last week" was rejected but I think it's fine. I realise the le indicates a change of state showing that he caught it last week

[ASZ18101849]

I wrote "Last week he had a cold" and it was accepted.

[MontserratMunoz]

Last week he caught a cold. This should be accepted too?

[Gabrielle145359]

Yes.

[tsaaga]

does anyone know how the sentence would be different if it was "he had a cold last week"?

[Gabrielle145359]

In that case, there would probably not be a 了. The 了 at the end indicates that this is a new situation.

[ThieumL]

Well... Before getting a cold you are usually fine, so there IS a change of state. Do not think in English, think the Chinese way! It relies way more on context than English does.

下雨了 It's raining (It was not raining a minute ago/one hour ago / yesterday)
昨天下雨了 It rained / was raining yesterday

生病了 I'm sick
昨天生病了 I was sick yesterday / I got sick yesterday / I had a cold yesterday. I still might be sick today, or maybe not.

Chinese relies on context to convey more precise information. Don't think in English. 了 here indicates a change of state, it does not give any clue about it's completion. Well, technically speaking, the change itself happened and has been completed, but we don't know about the new state this change led to. I'm not sure I'm clear haha...

He caught cold last week

[Dave168907]

I wonder why there is no 个 after 上 .

[ThieumL]

Both are right

[Jonny499474]

Would also like to see an answer to this!

[George792719]

Me too. For all of this course so far 个 always follows 上 . You get marked wrong if you forget it. Now 个 suddenly can be eliminated.

Dabbling in the dark here.

[ThieumL]

It's not about following 上 or 下, it's about being before 星期. You can omit it before 星期.

[Marin470782]

The scary thing is, being a good test-taker, I am starting to speak English like a Duolingo robot! Help!

[Sora942232]

I wrote "caught cold" and got marked wrong, though "catch cold" is also correct...

[Ben71191]

"He was sick last week" would suffice as well.

[ClassicalMood]

There are too many kind of sicknesses. It needs to be specific.

[Marin470782]

He caught cold last week is still being rejected, although someone else protested about this 6 months ago.

[Marin470782]

why was the last item marked wrong when I omitted 是， which is omitted here to say 'he had a cold'?
