Over time, the cuckoo(杜鹃) has learned to get other birds to care for its babies. The cuckoo is an amazing bird.
Most birds lay their eggs and look after them until their babies hatch out(孵化). Then they feed their babies until they are ready to leave the nest.
Some birds are not such good parents. Cuckoos lay their eggs in the nests of other birds and do not care for their own babies. The cuckoo gets other birds to act as the parents. The other birds are left with the work of bringing up the young cuckoos as well as their own babies!
If the cuckoo egg hatches first, the baby cuckoo will often push the other eggs out of the nest so that it can get all the attention of its new mother. The young cuckoo sometimes even pushes the other babies out of the nest. The young cuckoo has a loud cry and is often bigger than the other baby birds. It will take all the food and the space in the nest.
A cuckoo lays around 25 eggs each year in the nests of other birds. This means that many other birds spend all their time looking after young cuckoos instead of their own babies. Some birds have learned to recognize(辨别) the cuckoos’ eggs and they push them out of their nest. But the cuckoos have also found ways of fooling the other birds. They can change their egg to make it look just like the other birds’ own eggs.

Over time,I did get a little bit faster. However, I was really slow. In races, I would finish close to last. I'd always have to stop more than once, especially in the longer races, which were 2. 5 to 2. 8 km. After every race, I'd go home and cry. But 1 still didn't stop running, holding onto that picture of crossing the finishingline and finally doing well.
Then one of my friends joined the team, too. She could run easily and even came in the 18th in a big race! I felt so slow and my confidence(自信) was lower than ever. I became so nervous when I thought of the races that I wanted to give up badly.
Still. I refund to. Finally. 1 realized that the reason I was to nervous was that I was always worried that I wasn't ready for them. So a few weeks before the next 2. 8-km race. I practiced running almost 3 km every day. which helped me improve my pace(步伐).
When the time came for the big race, all that practicing really paid off. I stopped only once and my pace was so much better.
I realized that I’d finally gotten happiness with running. But the funny thing was. It didn't come from doing better, Instead, it came from the fact that I hid tried harder and never given up.
