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.
