Pasty Smith has raised ducks for many years. One of her ducks, Peg, losing one of his legs in a fight with a tortoise. Mrs. Smith called for help to see if anyone could create new leg for Peg. Three students thought they would probable use their 3D printer to create a leg for him! They spent several months create and testing different model. It turned out to be a lot more difficult than they had thought! Luckily, their hard work was paid off and they created a model who fitted Peg's leg perfectly! Now, Peg can walk or even run just like her duck partners! And Mrs. Smith is very thankful for them.

Luck has always been my closest friends these past five years. As you already know, there are a lot of forest fires during the summer season. Many forests are bad burnt each year.

This hot summer, not far from our house, a forest caught that fire. It is in July and a heat wave had been going for three days. Luck rushed towards a forest. There was no long any hope at that moment to wait for Luck to come back. Later a fireman ran into my house and told me what my dog Luck succeeded in saving four cats where were caught in the fire. According to the fireman, Luck caught the cats, move them one by one into a safe place.

After the Tangshan earthquake, a story was told that a fox had saved a man’s life. The man worked at a power station. He liked fishing in its spare time. He usually keeps the fish he had caught in a tank. But these fish often were missing. Then he caught a fox when it was eating the fish. Instead punishing the fox, he let it go.

One night, the man was woken up by loudly noises outside. He went out and find the fox standing there. Surprisingly, it stood in the front of the man to prevent him from go back into the room. Sudden, a big earthquake happened but then the house was destroyed. It was the fox’s help which saved his life.
