Answer :
To determine whether each sentence is a zero conditional (ZC) or a first conditional (FC), we'll start by understanding the difference between the two conditionals:
Zero Conditional (ZC): This is used to talk about general truths, scientific facts, or situations that are always true if the condition is met. It uses the present simple tense in both the 'if' clause and the main clause. An example could be, 'If you heat water to 100 degrees Celsius, it boils.'
First Conditional (FC): This is used for situations that are possible or likely to happen in the future if the condition is met. It uses the present simple tense in the 'if' clause and the 'will' future tense in the main clause. An example is, 'If it rains, we will stay indoors.'
Now, let's determine whether each sentence is ZC or FC:
If the weather is sunny, we'll play basketball outdoors. (FC) - This is because it describes a future possibility dependent on the weather being sunny.
If you join the swimming team, you'll have to train after school. (FC) - This is a potential future situation dependent on joining the team.
If I do exercise every day, I feel more energetic. (ZC) - This describes a general truth or habitual result of exercising daily.
If the team trains every day, they'll win the competition. (FC) - This predicts a future outcome based on whether the team trains daily.
If the ball touches the ground, you lose a point. (ZC) - This is a definite rule in some games, thus a general truth.
If you want to get fit, you'll have to join a gym. (FC) - This is a potential future action based on a desire to get fit.
If you take part in a team sport, you'll make new friends. (FC) - This predicts a likely future result based on participation.
If you take up running, you need special shoes. (ZC) - This suggests a general truth that to run, having special shoes is generally necessary.
