Ex. VIII. Make sentences about the recent economic performance of either a company you know well, an industry you know about, or the economy of your country. Grammar: The Infinitive

Presentation

Ex. I. Read one more text about Walter Raleigh paying attention to the underlined words. What part of speech are they?

Walter Raleigh brought from America not only tobacco plants but also a sack of potatoes, which were then quite unknown in England. He had them planted in a field and when he got the first crop he was glad to send some potatoes to a friend of his.

The friend did not know how to cook them so he asked his wife to fry them in butter. The wife decided to serve the new dish with sugar and cinnamon. However, the fried balls were hard and it was unpleasant to eat them. They thought it was too cold in England for the American potatoes to become ripe enough. So the man ordered the servant to throw the potatoes away and burn them. When the fire had died down and there were only ashes left, the man happened to step on a potato lying in the ashes. The potato split and it seemed to be white and soft inside. Then the man picked up the split potato, which now had a pleasant smell and tasted it. The taste was very pleasant, too.

Thus the right way of cooking potatoes was found and soon a lot of people were enjoying them.
