Sure, here's an example paragraph:
Informative text (Topic: Global Warming)
Global warming is a phenomenon that is caused by the increase of greenhouse gases in the Earth's atmosphere, primarily carbon dioxide. These gases trap heat from the sun, leading to a gradual rise in global temperatures. The main sources of greenhouse gases include the burning of fossil fuels such as coal and oil, deforestation, and agricultural practices. As a result of global warming, we are already seeing a range of impacts, including melting ice caps, rising sea levels, more frequent and severe heatwaves, droughts, and extreme weather events such as hurricanes and floods. To mitigate the effects of global warming, it is important to reduce our greenhouse gas emissions by transitioning to clean and renewable energy sources, improving energy efficiency, and implementing sustainable land use practices.
Demonstrative text (Topic: Making a Cup of Coffee)
To start making a cup of coffee, first, grind the coffee beans to the desired fineness. Then, measure out the coffee grounds and add them to a filter in a drip coffee maker. Next, fill the coffee maker with the desired amount of water and turn it on. The water will then drip through the coffee grounds and into the pot below. Alternatively, you can use a French press by adding the coffee grounds to the press, pouring in hot water, and then pressing down the plunger to separate the coffee from the grounds. Once the coffee is brewed, pour it into a mug and add any desired milk, cream, or sweeteners. Enjoy your freshly brewed cup of coffee!
