Robots have built a big house in Switzerland ...

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.

5G technology will create many big changes in our lives, including the way we receive medical treatment.

One of the most exciting uses is telesurgery (远程手术) . This is when a doctor does surgery(外科手术) on a patient even though they are not in the same place. China has been leading the way in this field. For example, In January 2019, the worlds first telesurgery was done in Fujian. Using 5G, a doctor controlled robotic arms to do surgery on a test animal. In March, China’s first brain surgery was completed by a doctor who did on a patient 3, 000 miles away. In August, robots guided by Beijing doctors did a test surgery in three different places at the same time. These things couldn’t take place without 5G. The high speed of 5G means there is no lag(滞后)between a doctor’s movements in one place and robots, in another.

5G will also make health care easier. Before receiving treatment, patients will be able to make HD video call(高清视频电话) with their doctors. The doctors will be able to advise patients who can’t visit a hospital in person. Patients can also put on wearable device（设备）that can end information in real-time to doctors. This allows doctors to monitor patients from their homes.

5G technology will make sure that everyone can get good health care. When 5G is fully used in the medical field, we will have a world where telesurgery and home health care become common.

1.From the examples in Paragraph 2, we can know that ___________.

A.Chinese doctors are patient and hardworking

B.China has been leading the way in telesurgery

C.robots are widely used to do surgery in hospitals

D.doctors often practise how to use robotic arm

2.The device that patients wear can ____________.

A.make HD video calls B.control robots to do surgery

C.give them health care D.send information to doctors

3.Which part of a magazine can we read the text?

A.Technology B.Geography. C.Education D.Culture
