Explanation/Explicação
In March we are talking about Grammar. This week we continue talking about Conjunctions in English.

• We use unless to say talk about an action that is conditioned by another.
  Example: You can’t drive unless you have a drivers license.
  
  
• We also use unless for warnings.
  Example: You won’t pass the exam unless you work much harder.
  
  
• It is often possible to use if not instead of unless.
  Example: Charles won’t pass the exam if he doesn’t work hard enough.
  
  
• We use as long as or so long as  or provided or providing with the meaning of if or in condition of.
  Examples: You can borrow my dictionary as long as /so long as you don’t damage it.
  Driving a car is convenient provided / providing that you have somewhere to park.
  
  
• Note that when you use unless, as long as and provided/providing you shall not use the future to talk about the future, you must use the present.
  Examples: They will be late unless they hurry.
  Providing he studies hard, she will pass the exam.
