Give us today our daily dose .

It's really incredible how this exercise can change your English in one month. The idea is to create a blueprint of the verb tense system in your head. It works with key words. You should change the sentence, which you can make up, according to the given time words.

TRY THIS!!!
The first time you do it, it should take you about 30' to do the whole battery, as you get more familiar with the words, time should be reduced until you are doing it automatically (3 to 5 minutes). You will not believe your mastery of verb tenses after one month!!!!!!!!!!!!!!!!!!!!!!
