Answer 1

1.If I give this phone to charity, they will find someone who needs it.

2.If this tap does not stop dripping, how much water will we waste in a day?

3.The situation will become worse if they do not change their behavior.

4.Look, the battery is full! If you do not disconnect the charger, you will waste energy.

5.If she reads this book, she will understand the situation better.

Note: The unless construction is typically used in negative conditional sentences, so it might not fit naturally into these positive conditionals. However, if you'd like to incorporate "unless" into one of these sentences, you could use it in the negative part of the statement. For example:

The environment will suffer unless we recycle more.

The situation will become worse unless they change their behavior.
