Here's a nice exercise that you could try: Take a good sentence from one of my lessons, and rewrite it using the exact same structure but different information. Here are two examples:
1) More waste goes to landfill sites than to any other refuse management facility.
Now I'm going to use the same structure, but invent some new information:
More British people go on holiday to Spain than to any other country.
2) Austria and Belgium are the most environmentally friendly of the fifteen countries, recycling around 60% and 50% of their waste respectively.
Again, I'll invent my own sentence using the same structure:
Apple and Google are the most successful of the five tech companies, recording profits of $45 billion and $20 billion respectively.
Can you create your own invented sentences using the two models above, or by choosing a different model sentence from one of my lessons?
