4. Unless means except if or simply it means if...not. Both of these examples have the same meaning and refer to the present time. "You can't go on vacation unless you save some money." "If you don't save some money, you can't go on vacation." "You will feel cold if you don't wear a coat." "You will feel cold unless you wear a coat."

5. Unless is good to use when it highlights an exception to what is generally true. In this example I only have one reason why i may be late: traffic (vehicles on the road): "I'll arrive at 10am unless there is traffic." "I'll arrive at 10am if there isn't traffic." This next example shows us that sometimes the context can change and unless is not exactly interchangeable with if...not. "I'll be annoyed if I do not arrive at 10am." - Being late will annoy me. "I'll be annoyed unless I arrive at 10am." - The only thing that can stop me from being annoyed is arriving at 10am.

8. Zero Conditional If you heat ice, it melts. We use the zero conditional when the result of the condition is always true, like a scientific fact. Take some ice. Put it in a saucepan. Heat the saucepan. What happens? The ice melts (it becomes water). You would be surprised if it did not. ifconditionresult Present SimplePresent Simple Ifyou heat ice,it melts. Notice that we are thinking about a result that is always true for this condition. The result of the condition is an absolute certainty. We are not thinking about the future or the past, or even the present. We are thinking about a simple fact. We use the Present Simple tense to talk about the condition. We also use the Present Simple tense to talk about the result. The important thing about the zero conditional is that the condition always has the same result.

9. Look at these example sentences: ifconditionresult Present Simple IfI miss the 8 o'clock bus, I am late for work. IfI am late for work,my boss gets angry. resultifcondition Present Simple I am late for workifI miss the 8 o'clock bus. My boss gets angryifI am late for work.

10. First Conditional for real possibility If I win the lottery, I will buy a car. We are talking about the future. We are thinking about a particular condition or situation in the future, and the result of this condition. There is a real possibility that this condition will happen. For example, it is morning. You are at home. You plan to play tennis this afternoon. But there are some clouds in the sky. Imagine that it rains. What will you do? ifconditionresult Present Simplewill + base verb Ifit rains,I will stay at home.

11. The important thing about the first conditional is that there is a real possibility that the condition will happen. Notice that we are thinking about a future condition. It is not raining yet. But the sky is cloudy and you think that it could rain. We use the Present Simple tense to talk about the possible future condition. We use will + base verb to talk about the possible future result. Examples: ifconditionresult Present Simplewill + base verb IfI see Mary,I will tell her. resultifcondition will + base verb Present Simple I will tell MaryifI see her.
