WASHINGTON – It’s a great achievement that inspires notions of robots with consciousness and independent minds.
When people or animals get hurt, they can usually compensate for minor injuries and keep limping along, but for robots, even slight damage can make them stumble and fall. However, a recently made robot has demonstrated a novel ability: it can heal its own damage.
The new robot, which looks like a splay – legged, four – footed starfish can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unfamiliar places. “There is a need for planetary robotic rovers to be able to fix things on their own,” says Josh Bongard, a professor in the University of Vermont, who is one of the device’s creator. “Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program, but the new robot works differently. First, sensors in its four legs observe the robot’s movements and signals to its built – in computer. From the formation it collects, the robot creates its own programs that allow it to adapt to different situations. For example, when the researchers shortened one of the robot’s legs, the smart machine simply adjusted its way of walking – it used three legs instead of four.
The researchers are looking for other places to put the resilient robot to work. One pellicle spot is the ocean floor. That dark and dangerous undersea terrain might be a good choice for a robot the scientists call the Starfish. “We never officially named the robot, but we usually refer to it as the Starfish, even though a real starfish has five rather than four legs,” says Bongard. “Also, a real starfish  is much better than our robot at recovering from injury, because it can actually grow its legs again.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.
46．The newly designed robot distinguishes itself from the former ones because it___________
A．can communicate with people on the earth about their problems
B．works according to a certain computer program
C．can find its problems and solve them automatically
D．can explore unfamiliar places
47．An example is given in the fourth paragraph in order to explain that the robot ___________
A．is used to create new programs
B．has typical robot functions
C．has sensors to observe its movements
D．can gather information and adapt to new conditions
48．The underlined word “resilient” in the last paragraph means the robot is ___________.
A．creative    B．newly made     C．able to recover    D．informative
49．Which of the following is TURE about the robot “Starfish”?
A．It was spoken highly of by people for its special ability?
B．It will stumble and fall if damaged.
C．It can grow its legs again once they are broken.
D．It has started to work on the ocean floor.
50．What might be the best title of the passage?
A．How does the Starfish Robot work
B．Do – It – Yourself Robot Repair
C．Robots Designed to Work On Other Planets
D．New Robot Helping Us In Many Ways

So you thought the hamburger was the world’s most popular fast food? After all, McDonald’s Golden Arches span（跨越）the globe（全球）. But no, there is another truly universal fast food, the ultimate（极好的）fast food. It’s easy to make, easy to serve, much more varied than the hamburger, can be eaten with the hands and it’s delivered to your front door or served in fancy restaurants. It’s been one of America’s favourite foods for over 50 years. It is, of course, the pizza.

It’s kind of silly to talk about the moment when pizza was “invented”. It changed over the years, but one thing’s for certain—it’s been around for a very long time. The idea of using pieces of flat, round bread as plates came from the Greeks. They called them “plakuntos” and ate them with various simple toppings（配料）such as oil, garlic（大蒜）, onions and herbs. The Romans enjoyed eating something similar and called it “picea”. By about 1000 AD in the city of Naples, “picea” had become “pizza” and people were experimenting with more toppings: cheese, ham, anchovies and finally the tomato, brought to Italy from Mexico and Peru in the sixteenth century. Naples became the pizza capital of the world. In 1889, King UmbertoⅠand Queen Margherita heard about pizza and asked to try it. They invited pizza maker, Raffele Esposito, to make it for them. He decided to make the pizza like the Italian flag, so he used red tomatoes, white mozzarella cheese and green basil leaves. The Queen loved it and the new pizza was named “Pizza Margherita” in her honour.

Pizza went to America with the Italians at the end of the nineteenth century. The first pizzeria in the United States was opened in 1905 at 53 Spring Street, New York City, by Gennaro Lombardi. But the popularity of pizza really exploded when American soldiers returned from Italy after World WarⅡ and raved about(夸赞) “that great Italian dish”. Americans are now the greatest producers and consumers of pizza in the world.

1.Which is the correct order of the changes of pizza?

A．Plakuntos→pizza→picea                  B．Pizza→plakuntos→picea

C．Picea→plakuntos→pizza                  D．Plakuntos→picea→pizza

2.Why are Mexico and Peru important in the development of pizza?

A．Because pizza first became popular in these countries.

B．Because pizza was invented in these countries.

C．Because one topping was brought to Italy from these countries.

D．Because people there are the greatest consumers of pizza.

3.What do the Italian flag and a Pizza Margherita have in common?

A．There is a picture of a Pizza Margherita.      B．They have the same colours.

C．Both of them represent Italy.               D．They are both popular in Italy.

4.When did pizza become really popular in the United States?

A. After 1945.      B. In 1889.     C. In 1905.         D. By 1000AD.

5.What’s the best title of the passage?

A．McDonald’s and Pizza                   B．Global Pizza

C．Pizza in the United States                  D．How to Make Pizza
