I can help you with your question. You are asking about the correct forms of the construction "there is / there are" in English. Here is a brief explanation and some examples:

- "There is" is used when there is one thing or person in a certain place. For example: There is a cat on the sofa. - "There are" is used when there are more than one thing or person in a certain place. For example: There are two cats on the sofa. - The preposition that follows "there is / there are" depends on the location of the thing or person. For example: There is a sofa in front of the window. There is a sofa behind the window. - The preposition "on" is used when something is on top of another thing. For example: There are some books on the sofa. - The preposition "under" is used when something is below another thing. For example: There are two cats under the sofa. - The preposition "next to" is used when something is beside another thing. For example: There are some books next to the sofa.

Based on this information, you can fill in the blanks in your sentences as follows:

1.) There are two cats under the sofa. 2.) There is a sofa in front of the window. 3.) There are some books on the sofa.
