Or there is a picture of a living room. The students are asked to describe the picture using "there is" and "there are". What if a student says: "On the left is a table, at the back is a television, above it is a picture...". Do you say "that is also correct English" ? Then why would people bother to use "there is"? At least Czech students would not, as we don't have such a grammar expression in Czech. It exists in German (es gibt), in French (il y a), in Italian (c'e ) etc but not in Czech so most students keep forgetting to use it.
Thanks for the reply, Roberta.
If you tell the students that they must use "there is" and "there are" in the answer and they don't, then they're wrong. If the specific assignment is to do something and they don't do it, it doesn't matter whether the answer is right. They didn't follow instructions.
You might want to consider giving partial credit for something written in correct English even if they didn't follow instructions. But I wouldn't mark them as correct.
Example: I'm told on a test to write the answer in the past tense. I use the future tense. What I write is perfect, but I'm wrong.
Stach, This is more a teaching question than an English question. I can take you only so far with this.
As for the necessity of "there are" and "there is. " Sometimes they're necessary, and sometimes they're not. It depends on the construction.
There are three people in the room. (correct)
Three people are in the room. (correct but non essential)
There are countless ways to cook green beans. (correct)
Countless ways exist for cooking green beans. (This is more challenging; some rewording is necessary to make it work. Hence, "there are" and "there is" are essential to the construction.)
