Thanks a lot!!!!

Hi there.I have problems with task 2.question 6-I have written(She might have been coming down with flu.What have I done wrong.Could you help me.

Hi ljudamed,

The continuous form ('might have been coming down with') is not correct here because you are not speaking about this woman becoming ill, you are speaking about the possible reason she stayed home. In other words, you're not speaking a process, but a result, so the simple form ('might have come down with') is the correct form, not the continuous.

Does that make sense?

Excuse me, I have a question:

Why the prediction for the third person (He) it use 'have' not 'has'?
"He might have shot the victim"

Best Regards,

Hello Adroi,

'have' is not a conjugated verb here - that is why 'has' is incorrect after a modal. This form is explained on our modals + have page.

Hello! Why doesn't Rob use the article in these sentences " it could be _tea. perhaps it's _tea."

Hello Prime,

The definite article isn't appropriate here because he's simply identifying that it is tea. An indefinite article isn't appropriate because the tea is not being mentioned for the first time, and in addition, indefinite articles aren't used with uncount nouns - in this case, 'tea' is uncount.

You can read more about all of this on our definite article, indefinite article and uncount nouns pages.

Hi rosario70,

Rob says 'A woman was lying on the floor and there was a teacup next to her' at that point, and Stephen says 'We might have run out of time, Rob'.
