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.

Nature is all around us. We see it every day. It’s the sunset, the sunrise, the song of birds, the blooming оf flowers, the wind that blows, etc. These signs are an integral part of our lives. On the one hand we cherish these natural blessings, on the other hand – we don’t appreciate fully their importance. Thus, our future generations can be cut from these treasures. They might see less of natural wonders, because the humanity gradually destroys forests and kills some species of animals. It all happens due to industrial revolution and the growing number of chemical plants. Humans are the only species on our planet that consciously manipulate the environment. Unfortunately, we are poor leaders in this hierarchy, if we can’t increase the awareness of ecology. People are too self-centered to notice how badly they treat the surrounding environment. For thousands of years they lived in harmony with nature till the development of civilization. They could use the natural riches limitlessly, while today we have to use all the resources sparingly. Pollution is another threat to nature.
