Spring

What's your favourite season? I think (I) is spring.
Birds, (SING) in the trees, tell us that winter is finally over. The animals that (BE) asleep for months wake up and start to look for food. The days are much (WARM) than they were in the winter, so the plants start to grow, too.
The countryside (LOOK) fresh, beautiful and alive. We can leave our coats and umbrellas at home when we go out. And unlike in the summer, the sun (NOT BURN) our skin when we spend a long time outside.
The (GOOD) thing of all about spring, though, is knowing that the summer is not far away!
