There are many ways to add emphasis to your words in English
One way is simply to add words and phrases to the sentence such as especially, always, particularly, in addition, etc.
- I like to work outside, particularly in the fall.
- I especially like to work outside in the fall.
Another way is to repeat words or phrases to create emphasis.
- That ride made me sick. It just kept going around and around.
- I have told the kids over and over to call home if they are going to be late.
A third way is through the use of do or did as an auxiliary verb in a positive sentence. When put it in front of a base verb, it emphasizes the action of the verb. Sometimes it is used to emphasize the opposite of what a person believes.
