Many people enjoy going to the zoo. The Moscow zoo is one of A. the best places to go with children on the weekend or over the school holidays. It is located in the very center of Moscow, next to the Garden Ring and the Moscow Planetarium. The Moscow Zoo B. was opened in 1864 by professors of Biologe from the Moscow State University. It was rather small at first. In 1929, an additional territory was added to the zoo, and in 1990, the zoo C. became even larger. There are over 5000 birds and animals living in the zoo now, including elephants, giraffes, kangaroos, tigers and lions. Some people not only D. visit the zoo, but also help the zoo take care of its animals. It is possible to choose an animal and become E. its sponsor. Sponsors usually pay 50% of the cost of the food that the animal needs.

History contains a lot of stories about people who should have been a little bit more careful. In 1576 the explorer Sir Martin Frobisher sailed to the north of Canada trying to find a way to Asia. Unfortunately, he (find) COULDN’T FIND it, but during the voyage, his men landed on Baffin Island as they(look for) HAD TO LOOK FOR food and shelter. Here he discovered some rocks which he thought contained gold. When he returned to England he showed the piece of rock to people who agreed that it was gold, and Frobisher returned to the island with a larger ship. It was a difficult journey, as the ship (avoid)COULDN’T AVOIDhuge icebergs. On the island there were polar bears which (kill) SHOULD HAVE KILLED a man quite easily. And Frobisher was worried that someone else would get to the gold first. Perhaps he (tell) SHOULDN’T HAVE TOLD so many people about his discovery, he thought. But he (worry) DIDN’T NEED TO WORRY about his secret. He found the place again, and his men (work)COULD WORKin the freezing weather to dig for the gold. They returned to England again, and this time he (stop) DIDN’T HAVE TO STOP his discovery from becoming generally known. More and more people wanted to go to Baffin Island, and the next year the ships came back with hundreds of tonnes of gold. Unfortunately, this is where things went wrong. When Frobisher tried to sell the gold, he discovered that perhaps he (show)NEEDN’T HAVE SHOWED it to more people in the first place. The people he had showed it to had been wrong. They(tell) COULDN’T TELL the difference between gold and iron pyrite, a compound of iron and sulphur. Everyone laughed at Sir Martin and his men, and he (admit) HAD TO ADMITthat he had made a mistake.
