Grammar

First conditional (if + present simple, will + infinitive)

Use the first conditional to talk about things that are likely or possible in the future. The 'if' clause uses the present simple, and the main clause uses 'will + infinitive'. The clauses can appear in either order. When the 'if' clause comes first, use a comma. You can also use 'unless' (= if not) in the condition.

If you eat more vegetables, you will feel healthier.

You won't pass the exam if you don't study.

If she gets the job, she will move to Madrid.

Unless you wear sunscreen, you'll get sunburned.

Small Changes, Big Results

Many people want to be healthier but feel overwhelmed by the idea of making big lifestyle changes. However, research suggests that small adjustments can make a significant difference. If you walk for just thirty minutes a day, you will reduce your risk of heart disease by up to twenty per cent. If you replace sugary drinks with water, you will consume far fewer empty calories. Sleep is equally important — if you go to bed at the same time every night, your body will develop a more consistent rhythm, and you will wake up feeling more refreshed. Unless you take care of your mental health too, physical improvements alone won't be enough. Simple habits like spending time outdoors and talking to friends regularly will help you feel happier and more balanced.

1. What will happen if you walk for thirty minutes a day?

2. According to the text, why is mental health important?
