Chinese researchers have developed a robot to help doctors treat(治療) COVID-19(新冠肺炎) and other highly contagious(傳染的) diseases.

The machine can do some of the same medical examination tasks as doctors. Cameras record the robot's activities, which are controlled far away so doctors can avoid coming in close contact(接觸) with infected(感染) patients.

The robot's main designer is Zheng Gangtie, an engineer and professor at Tsinghua University. He said that he got the idea for the robot in January. At that time, the number of cases of the COVID-19 virus was rising quickly in Wuhan Zheng said a friend of his is the head of a hospital in Beijing. His friend told him that one of the biggest problems in dealing with COVID-19 was that healthcare workers were getting infected themselves. Zheng said he wanted to do something to help this situation.

So the engineer set up a team and went to work on it. The new robot is almost completely automated(自動(dòng)化的). "Doctors are all very brave," Zheng said. "But this virus is just too contagious...We can use robots to do the most dangerous tasks." However, Zheng said he had heard from some doctors that it would be better not to build such robots to be fully automatic. This is because many patients still desire(渴望) a human medical worker to help calm them during treatment.

The team has made two automatic robots by now and both have been tested by doctors at hospitals in Beijing. One machine was taken to Wuhan's Union Hospital, where doctors there were being trained to use it.

1.According to the passage, the two robots __________.

A.were almost fully automatic B.were both taken to Wuhan

C.were both made in January D.can only help fight COVID-19

2.Why does Zheng Gangtie want to develop the robot to help doctors?

A.Because his friend is the head of a hospital in Beijing.

B.Because the doctors are afraid to be in contact with patients.

C.Because many patients want robots to calm them during treatment.

D.Because doctors may get infected themselves when treating patients.

3.Which of the following is TRUE according to the passage?

A.Zheng Gangtie made the robots alone in Beijing.

B.Zheng Gangtie made lots of money by making robots.

C.Not all the doctors want the robots to be fully automatic.

D.The infected patients would like robot doctors to treat them.

4.The passage is probably from __________.

A.an advertisement B.a textbook C.a storybook D.a newspaper
