Spring is one of the four seasons in a year, which lasts from March to May in the northern hemisphere (北半球) and from September to November in the southern hemisphere (南半球). It is the time of year when the days start to get longer, the weather becomes warmer, and the world around us starts to come back to life.
What happens (发生) to the animals?
Animals such as grass snakes, lizards and frogs come out of hibernation on the first warm spring days. You might see frogspawn, which looks like jelly.
Hibernation: A time when animals rest and save their energy for the warmer months. Migrant birds: birds that go to a warmer country for the winter.

Some animals move about a lot more in spring, such as squirrels. You can see squirrels moving about, looking for food and climbing trees.
There are also lots of migrant birds that come back to the UK in the spring. You can see swifts, cuckoos and nightingales.
What happens to the plants and the insects?
Nature is very busy in spring and there are lots of changes. You can see the trees and bushes sprout (发芽) new leaves again in spring and many plants blossom (开花) because the air and soil are warmer and there are more daylight hours.
We can see many more insects in spring, including butterflies and bees, which like the flowers.
