Task 1.

Studies of the atmosphere first received technical support in 1912. Equipment to measure temperature and pressure was invented in Germany. But the question was how to raise it high into the air. In 1921, Russian engineers suggested using planes. The special equipment was put on planes that made regular flights. Thanks to this, scientists got a lot of new information about the structure of the atmosphere. Nowadays scientists use modern flying laboratories to study the structure of clouds at different levels. Unlike the first planes, these laboratories can work in any weather and are able to predict climate changes.

Task 1.

Wombats are exotic animals that only live in Australia. They have become an unofficial symbol of the country. In 1974 a wombat appeared on an Australian stamp for the first time. Since then it has been regularly used on different Australian stamps and coins. Wombats look like little bears and prefer grass to meat. They also love eating berries, plant roots and mushrooms. Like camels, wombats drink little water because there is enough water in fresh grass. Wombats spend most of their life in holes under the ground. With their strong arms and long nails they are able to dig very long and complex tunnels. Fortunately, wombats have few enemies in the animal world. Most wombats live around 15 years.
