Stative Verbs

Some verbs don't take the progressive tense.
Consider the famous advertising tagline:  "I'm loving it."  Everyone knows where this comes from however grammatically, it is wrong.  The verb love cannot take a progressive tense.
Here's a list of verbs that don't use progressive tenses:

love hate like see hear sound think (meaning "have an opinion") mind (meaning "care about") recognize seem have (meaning "own") prefer doubt consist of mean

eat drink go type read write listen speak watch say grow work sleep cook talk

All the verbs in green on the right CAN take the progressive tense.  They are considered 'dynamic verbs'.  
A common mistake most newcomers make is:"I'm having 3 daughters. (or 3 something)" - the proper form is:"I have 3 daughters.""I have a red car." This is about ownership and it cannot take the 'ing' form.There are many exercises you can do on the internet to help you understand this better.  Here is a very good website with an exercise for you:http://www.perfect-english-grammar.com/stative-verbs.htmlCopy and paste this into your Google browser.  Try the activities.If you have any questions, you can always email us.
