A start-up company in California, called Zume, is testing machines that make pizza. The robot takes and shapes dough to create the base of the pizza. It then adds tomato sauce, cheese, meat or other toppings. Next, the robot places the uncooked pizza into a hot oven. A few minutes later, the pizza is ready. The pizza comes out the same each time. Zume says the robots work quickly and do not get sick. The robots do not get paid either.

Julia Collins is the company’s founder and chief executive officer (CEO) . Her business can spend money on better food products because it does not have to pay the robots. Zume is using robots to make pizza.

Charity Suzuki has bought the robot-made pizza. She likes its taste. “It’s delicious. It’s always hot and fresh when it comes. I mean it’s great that they’re making it, but I can’t tell the difference that it’s made by a robot versus a human.”

Other companies say they are developing robots so people can get higher quality food faster. But what about the jobs the robots are taking from humans?

Ken Goldberg is a professor at the University of California in Berkeley. He also directs the school’s automation laboratory. Goldberg says researchers have been working with robots for 50 years. He says that, while there has been progress, the jobs are not going to disappear right away. “I want to reassure (使放心) restaurant workers that the skills that they have are still going to be of value,” Goldberg said.

“We’re going to get rid of boring, repetitive, dangerous jobs and we’re going to free up people to do things that have higher value. There’s going to be amazing new ways of working that don’t exist yet but are going to be created.”

   About ten men in every hundred suffer from color-blindness in some way. Women are luckier: only about one in two hundred is affected on this matter. Perhaps, after all, it is safer to be driven by a woman!

There are different forms of color-blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green — a strange world indeed.

Color-blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called "cones". These help us to see in bright light and to tell the difference between colors. There are also millions of "rods", but these are used for seeing when it is near dark. They show us shapes but no color.

Some insects have favorite colors. Mosquitoes（蚊子） prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky.

With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
