Picture the scene: You come home after work feeling too exhausted to cook –only to find a delicious meal worthy of a Michelin-starred restaurant waiting for you. It sounds like a fantasy, but it could be about to come true thanks to a robot chef developed by British scientists.
Those scientists have come up with a set of robotic arms so smart that they are capable of cooking meals all by themselves. The device will be sold from as early as 2017 as part of a purpose-built high-tech kitchen.
Scientists at Moley Robotics spent almost 18 years developing the hands. According to its creators, the arms can chop, stir, whisk and baste well enough to recreate almost anything you would care to eat, whether it is a simple home-cooked supper, or a complicated creation designed by a world-class chef. The hands move a little slowly, hovering strangely above the work surface whenever they are not busy, but they imitate human movements closely enough that they can do things such as wiping a spoon on the edge of a pan to prevent drips.
Mr Oleynik, who is leading the project, said, “All the things which are possible with the hand are possible here. There is no limitation. A lot of people want to go to Michelin-starred restaurants, but they are quite expensive and may be quite far from the home. This is an opportunity for people to enjoy very good food, and for a reasonable price. ”
The only cuisine that is off the robot’s menu at the moment is sushi, which requires extremely steady pressure and nimble（敏捷的；敏感的） fingers to make, but the team plan to conquer that as well by the time it goes on sale.
1.People go to Michelin-starred restaurants in order to_________.
A. appreciate car tires B. enjoy delicious meals
C. see the new robot chefs D. escape from work
2.What does the underlined word “they” in Paragraph 2 refer to?
A. British scientists B. The robot chef’s arms

3.Which kind of food CAN’T the robot chef cook at present?

4.What can we infer from the passage?
A. Hands of a robot chef can perform exactly like a cook.
B. Robot chefs are available at shopping malls.
C. Michelin-starred restaurants are suitable for many people.
D. It is uncertain when the robot can cook all kinds of food.
