know That...? An Industrial Revolution is a period of time when machines are invented and factories begin to appear which brings a lot of changes into peoples' lives. The Industrial Revolution began in Britain in the 18th century and spread to many of the European countries, such as Belgium, France, Germany, throughout the 19th and early part of the 20th centuries, as well as to North America.

Seasons and Weather

The year is divided into four seasons: spring, summer,
autumn and winter. In spring nature awakens from her long
winter sleep. The trees are filled with new life, the earth is warmed by the rays of the sun, and the weather gets gradually
milder. The fields and the medows are covered with fresh green
grass. The woods and forests are filled with the songs of the
birds. The sky is blue and cloudless. At night, millions of stars
shine in the darkness.
When summer comes the weather gets warmer still and
sometimes it’s very hot. It’s the farmer’s busy season — he
works in his fields from morning till night. The grass must be cut
and the hay must be made, while the dry weather lasts. Sometimes the skies are overcast with heavy clouds. There are storms
with thunder, lightning and hail.
Autumn brings with it the harvest-time, when the crops are
gathered in and the fruit is picked in the orchards. The days get
shorter and the nights longer. The woods turn yellow and brown,
leaves begin to fall from the trees, and the ground is covered
with them. The skies are grey, and very often it rains.
When winter comes, we’re obliged to spend more time
indoors because out-of-doors it’s cold. We may get fog, sleet
and frost. Ponds, lakes, rivers and streams are frozen, and the
roads are sometimes covered with slippery ice or deep snow.
The trees are bare. Bitter north winds have stripped them of all
their leaves.
