"Where are you at 9:30 tomorrow morning?"
How I remember time order is from broad/large/generic to narrow/small/defined in scale.
Because it's so logical! And it works just like numbers. (One thousand two hundred thirty four, for example.) Every language should work this way!
The English translated sentence is incorrect. It would be "Where are you all at 9:30 tomorrow morning?"
The ‘all’ is regional slang, which most Duolingo courses accept so that people can practice translating the plural, but it's not part of standard English.
From what I've seen so far, seems like adverbs go between the subject and the verb.
You can be singular or plural in English. This translation should not require us to include the 们 for those of us that are trying to learn using keyboards rather than choosing from a small list of words. As of 6 Sept 2018, not including the 们 is marked incorrect.
I use a keyboard so that I cannot get a hint by looking at the choices. But now I am forced to try to remember the details of specific questions rather than concentrate on language acquisition.
It is not. My guess is that this question was put up by a Northern Chinese (they say '哪儿' far more than '哪里'), which makes it a really biased one. I would say ‘明天早上九点半你会在哪里？’ (‘会’ as an indicator for the future tense) Also, the original answer is simply non-idiomatic. I have never met anyone saying literally that in my life
What I'm finding increasingly irritating about this course is that it puts you often in a position of having no choice but to get answers wrong because it often does not even present examples that you can learn from first. It then becomes guess work. I find this is wasting a lot of my time, and real negative in feeling I am making positive progress. The rest of the course and presentation are great.
I only use the keyboard. When the question just says "you" I am obviously going to assume 你。But, I'm told that is wrong and it is 你们。The question should specify somehow. It's the same with 她 and 他。 There is no way to differentiate by just hearing them. Duolingo should make things more specific for those who only use the keyboard.
