How to give a good presentation in English

Changing focus:

During your presentation, there may be times where you need to shift the focus, in order to make all of the points you wish to make. Drawing attention to any changes of focus can serve to give your presentation a clearer structure and can also help to keep the attention of listeners. Some examples of phrases you might use include:
“I would like to shift focus now to…”
“Next, we need to consider…”
“This leads me to my next point…”

Drawing attention to the slides:

In many cases, your presentation will include visual aids, such as slides on a screen, or handouts. The inclusion of visuals can help to back up the points you are making, while also making the presentation more interesting or exciting. To introduce your slides or other visual aids, you may find the following phrases helpful:
“If I could draw your attention to…”
“This chart/graph/table illustrates…”
“If you look up at the screen…”
“I would like to show you this…”
“On your handout, you may see…”

Summarising a presentation:

At the end of a presentation, it is important to summarise the main points you have made, so that you can remind listeners of what has been said. This is a chance to point out which parts of the presentation you think are especially important, and ensure everybody leaves with the key pieces of information. Useful phrases include:
“To summarise…”
“In conclusion…”
“I would like to recap…”
“To sum up what has been said…”
“So, we have covered…
