Is there a trainer of English language at the time?
Want free computer simulator. The machine needs the following: it displays the sentence in Russian that you need to prepare the English translation, namely, to choose the correct time. I give the answer, the trainer says is correct/not correct, maybe even why not right, move on to the next. The goal is 100500 times to try to pick a time and bring to the machine that is the skill of choice, without the knowledge of have/has V3 had been-ing-ed and other offal. And then I will repeat the school table.
