As I said in this blog we’re going to continue what we started with Subject-verb agreement. So, When sentences start with “there” or “here,” the subject will always be placed after the verb, so care needs to be taken to identify it correctly. For example: There is a problem with the balance sheet. Here are the papers you requested. If two infinitives are separated by and they take the plural form of the verb. For example: To walk and to chew gum require great skill. When gerunds are used as the subject of a sentence, they take the singular verb form of the verb; but, when they are linked by and, they take the plural form. For example: Standing in the water was a bad idea. Swimming in the ocean and playing drums are my hobbies.
