It's probably a programming error that "他 上星期 感冒 了“ is wrong?
We shall see. Reported.
And again 2019-01-11/01-16
And again 2019-01-20
Eight months later, reported multiple times and no action. They clearly do not have enough people to maintain the Chinese lessons.
I also reported it.
Already one year yet the answer is not accepted....
Native chinese here. It is absolutely fine and is accepted now. Verified on 11/4/2020
It's accepted now (2020-02-19).
I like how at various points in the tree the exercises reinforce a pretty strict, subject then time word order and then at random times completely drops it and penalizes you for picking up on the pattern.
I agree (and have reported it), the order they put it in is completely arbitrary and often leaves us having to guess which order they put it in each time.
the random pattern just got me too
他上星期感冒了 is just as correct
11 months later and the other answer is still not accepted!
Is了necessary when it is explicitly stated that the situation took place last week?
Sound for 了 should be "le"
I thought 了is not necessary when the context has already been made clear as past time.
I thought so too...
