de punta en blanco - wordreference is giving me a different definition. could this be reviewed? thank you!

What is the rule for using "mientras" or "mientras que"?

For example:

Escribo mientras que él come. Why can't I say: Escribo mientras él come.

Él habla mientras yo leo.           Why can't I say: Él habla mientras que yo leo.   

I cannot see any difference in syntax, usage or meaning between these two sentences, yet three native speakers have all told me they would only say the first, but could not tell me why or give me any grammatical rule.  Please help... someone/anyone.

Why is the usage of nosotros as above been marked wrong

In the quiz, the sentence was :  Vas a ir con ella al teatro.  I know that it doesn't sound quite right to say "Vas a ir consigo al teatro", but why would that be incorrect?

Is it common to use hacer as "gave" in this question?  Why not use diste (dar)? 

Is it safe to think that:

Haber tenido = sustantivo

Habiendo tenido = adverbio

Habiendo tenido ese accidente, depende de su pareja.

Haber tenido ese accidente lo hizo dependiente de su pareja.

Why in the following example is ser used? I thought that the estar form would be used because cheerful is a an emotion or feeling. Wouldn't this indicate that the group is "always cheerful"?

Ustedes ________ muy alegres. 

"Acordaos que estamos fríendo esta tortilla a fuego lento."

Shouldn't it be "de que"?
