No one wants to be in a life-or-death situation. However, if you are in a dangerous situation, what will you do, fight or flight?

When 13-year-old Joe Rowlands and his dad were in a kayak（皮艇） accident, the brave teenager chose to fight. He not only fought for his own life, but also saved his father's.

On that day, Joe and his father Paul were out on their kayak off the coast of Anglesey in the UK. Suddenly they noticed that the kayak was starting to fill with water. Then they found out there was a hole in the floor of the boat. Without another choice, Paul turned the boat over. He asked Joe to climb on top so that he could push the boat to a nearby island.

However, the rough （汹涌的）waves made it too hard for Paul to push the boat to land. They had to swim without the boat. Luckily, Joe made his way to the island safely. But when he looked back, he found his dad was no longer swimming. Risking his life, Joe jumped back into the cold water and managed to drag（拽） his dad up onto some rocks. Then Joe did CPR（心肺复苏） on his dad until he came around.

“I know I can never pay him back for saving my life and I'm very proud of him. He acted with courage beyond his years, "Paul said of his son.

    Robots have built a big house in Switzerland using 3D-printed materials. It is the first house made by robots for people to live in. It is more environmentally friendly and safer than man-made houses.

The creators say the big house will inspire the future of building. “This is a new way seeing architecture（建筑）,” said one of the creators. "How you build is important."

The big house was built completely from robot-made materials. It used 60% less cement（水泥）than a man-made house. Its ceilings（天花板）were made with a 3D printer. There are 35 parts in the house and each one was built in 60 to 90 minutes. It means that the robots built the full house in just 48 hours.

It is not the first time for robots to build houses. The Chinese used 3D printers to build 10 houses in a day in 2014. They created a building the next year. And last year Italians built a house in just 48 hours.

Scientists say one day they could send robots to build houses on the moon. We are curious about how we're building for the future.
