Future tenses, with time clauses

When we describe events and actions expected to take place in the future, we use future tenses. Remember we have future simple, future progressive and future perfect tenses. Don't forget when we have time clauses, the verb in the time clause is usually in the present tense not in the future tense.

Example1:
What I expect to happen in the next 10 years of my life is as follows:
After I graduate (instead of will graduate) from this school, I think, I will take a long holiday and travel in Europe. When I start (instead of will start) work, I will not have much time for myself. Therefore, I want to see Europe before I start will go to England, France, Spain and Italy. If you take (instead of will take) a Eurorail ticket, you can travel inexpensively. So I will not have to spend too much for my travel expenses. After I come (instead of will come) back to Turkey, I will start looking for a job. I will accept a job that fits my life style expectations. I do not want (instead of will not want) to work long hours.

Example2:
Some authorities report that the world climate is changing drastically and will continue to change in the future too. A new ice age is expected. If we have a new ice age, Northern Europe will become very cold, as cold as Siberia, in fact. Countries like Turkey will turn cold too. If temperatures drop by 10 degrees Centigrade, this will affect life and some species won't be able to live (will not = won't) in those regions.
