Sir Walter Raleigh (was) an English traveller who (lived) in England in the days of Queen Elizabeth. He (sailed) across the seas to America in search of new lands. He (brought) to England two very important plants: the tobacco plant and the potato. When he (was) in America, he (learnt) to smoke from the Indians. When he (was) back in England, he (was sitting) one day in his room by the fire smoking a pipe. His old servant who (knew) nothing about tobacco or smoking, suddenly (came) into the room and (saw) the smoke coming out of his master's mouth. He (was) frightened: he (thought) Sir Raleigh (was) on fire. He (rushed) out of the room, (got) some water and (threw) it all over his master before Sir Walter (could) explain that he was simply (smoking). Sir Raleigh (brought) the potato to his country because he (wanted) the people (to learn) how (to grow) potatoes. He (said): "When the harvest (is) poor, there (will be) no breed and we (shall all be) hungry. You (will) never be hungry if you (grow) potatoes. But people (did not like) potatoes. Nobody (wanted) (to eat) them because nobody (knew) how (to cook) them."After many years a Frenchman (found) the best way of growing and cooking the potato. People (began) (eating) potatoes and (found) them good. Since that time more and more potatoes (have been grown) and (eaten) in Europe. The potatoes (have become) one of the most important and useful vegetable.

Your friend: Let's go to the café together. 

You: I'm sorry, but I have to get my parents' permission. It is a rule in our family. I hope I can go. Do you have to get your parents' permission if you want to go somewhere?

Your friend: Yes, I do. I have to ask my parents before I go anywhere, too. I think it is fair. Do you have to follow some other rules?  

You: Yes, I do. For example, I should ring them up if I have to delay for some reason and return home later than they await me to. But I think these rules are all wise.  

Твой друг: Давай сходим вместе в кафе.

Ты: Прости, но мне нужно спросить разрешение родителей. Это правило в нашей семье. Надеюсь, я смогу пойти. А ты должен получить разрешение своих родителей, если хочешь пойти куда-то?

Твой друг: Да, конечно. Мне тоже надо спросить родителей, прежде чем куда-то идти. Я думаю, что это правильно. У вас есть другие правила, которым ты  должен следовать?  

Вы: Да, есть. Например, я должен позвонить, если мне по какой-то причине придется задержаться и вернуться домой позже, чем они меня ждут. Но я думаю, что все эти правила мудры.
