a This option is more difficult to understand, in Chinese you can ask this sentence You went **? But it's strange to say this in English, because Chinese say it Chinese you'll know that you're talking 1Didn't pick up **2 in the morning

So you went**? Two related things. But in English ask where did you go

This is one thing, and it has nothing to do with not answering ** in the morning. Others will think it's strange for you to say this, and you have nothing to ask him what he went to ** for.

b.Here, this is asking you right now? Note that this sentence is not something that can be said in person, and ask him if he is in ** when you hit **. I want to be more interested in asking, he didn't pick up **, and he went to ** at the time.

When I called you this morning, no one answered. What are you**?

Now it's time to ask me **, you're **. Instead of asking you if you've been**, option a is you've been**, you go doesn't match.

Option b emphasizes that now, You Gone, does not conform to the original meaning.

At that time you were in ** you, compound the meaning of the original text.

There are often two situations in the past tense: one is that the context of the sentence is in the simple past tense, and the other is that the sentence has an adverbial that indicates the past time.

Although these two sentences have no context and time adverbials, the verb rang in the first clause uses the simple past tense, so the main clause uses the past continuous tense instead of the present continuous tense.

When there is no time adverbial in the sentence, if it indicates a specific ongoing action, it is generally okay to use the past continuous tense or the present continuous tense. The second sentence above can also be used in the present continuous tense if it is based on Chinese only.

。。。He's talking about what happened to him before. If you want to say what's happening to you right now, you use the present tense.
