Я вообще не могу ни чего понять!!!!

1. I can't do this exercise. It's too difficult 2. This soup is horrible. It hasn't got enough salt 3. The police officer stopped him because he was driving too fast 4. We can't play basketball today because it's too hot  5. Donald won't go scuba diving because he is not  brave enough 6. Let's leave this cafe. It's too crowded 7. These sandals don't fit me. They aren't big enough 8. I can't come shopping with you today! I haven't got enough money
