Shanghai Renji Hospital broadcast (播放) a cancer operation, using 5G technology first in China with the Da Vinci Robotics System. It is the 11 robotic system for difficult operations.
The broadcast 12 doctors in Renji Hospital’s Ningbo branch (分院) in Zhejiang and their 13 in Shanghai to watch each step of the operation at the same time.
The patient was a 65-year-old woman. She had cancer. The degree of difficulty for the operation was high. The 14 was performed by Doctor Zhong Ming.
The hospital’s Ningbo branch was in service in March. But Zhong Ming, who works in both hospitals, soon found that the doctors in Ningbo did not have enough 15 to watch difficult cases and master medical techniques. The hospital came up with the 16 to air a live broadcast of an operation.
Doctors in Zhejiang are able to watch the details of the difficult operation with a wider view. The doctors can see clearly 17 Zhong operated on the woman.
Zhong said that 18 they had tried to use other technologies during such broadcasts, but none of them is clear or 19 enough. The 5G network helps the medical circle solve the problem.
Maybe one day, we’ll be able to watch a(n) 20 broadcast of an operation in Shanghai through our phones with 5G network. Such broadcasts are good for young doctors to learn the most modern technology to treat more patients.

What will the schools of the future look like Smart campuses are being built all over the world. Their high-tech features help students 61 more effectively, as well as bring convenience to 62 .
A university has created Canada’s first 5G-powered smart campus. The school worked with a tech company 63 a 5G network across its campus. Their researchers can use the network to test 5G software.
At Staffordshire University in the UK, many students enjoy talking to Beacon and 64 it questions. Beacon is an AI chatbot that was developed by the university. They can ask it questions, such as whether or not one of their classes is cancelled (取消).
Amazon also sells smart campus 65 . Alexa, the company’s voice-activated (声控的) smart assistant, can be used to help teachers run their classes more efficiently.
People often 66 universities “mini-cities”. They often have their own transportation, roads, shops, and banks. Universities are seen as good 67 to test smart technology, because they have control over all of their buildings.
Long-distance learning 5G will be a big help for students who take online classes. With virtual reality (虚拟现实) systems, students will be able to see places like the Great Wall without 68 their classrooms.
In Australia, for example, many students live far away from 69 . They use webcams (网络摄像头) to talk to their teachers, but lag (滞后) and unstable (不稳定) connections make it a poor experience.

The smoke is mainly from cars and factories in cities. Poor air is bad for people’s health, 83 for children and old people. They fell ill easily and the 84 were full of people. They had problems with their noses and lungs.
So it’s necessary 85 people from doing so many bad things to the environment. For example, people should use cars less and 86 burn lots of coal and gas. The government needs to take measures to make factories stop pouring 87 waste gas into the sky.
Three students from No.4 High School in Beijing 88 a report to advise how to protect the environment. They suggested 89 people should plant more trees and let off fewer fireworks for celebration.
We hope more people will join us in 90 a difference. In this way, the sky will certainly return to good.

Emma was an 8-year-old girl who loved playing in the park near her house. She enjoyed the green grass, the tall trees and the little pond where ducks swam. But one day Emma noticed something 91 . There was trash everywhere: candy wrappers, soda cans and even plastic bags floating (漂浮) in the pond. Emma wanted to help. She decided to make a 92 .
The next day at school, she told her friends about her plan, “Let’s clean the park and protect our environment.” Her friends Jack, Lily and Sam agreed to join her. They called 93 the Green Team.
That weekend, the Green Team went to the park 94 gloves, trash bags and lots of energy. They 95 every piece of trash they could find. “Look, I find an old bottle!” Jack said. “I’ve got a plastic bag stuck in a bush (灌木丛),” Lily added.
By the end of the day, the park looked beautiful again. Emma smiled 96 and said, “We did it.” 97 she knew the work wasn’t over. “If we want the park to stay clean, we need to teach others how important it is to take care of nature,” she said.

Angela didn’t like seeing plastic waste washing up on the shore near her home.
She wanted to call on her community to clean it up, so she 101 an organization and called it Washed Ashore: Art to Save the Sea.
Here’s 102 it works. Volunteers help clean up 300 miles of shoreline (海岸线). Then, using only plastics 103 the beach cleanup, Angela and many volunteers create sculptures (雕塑) of sea animals. She says, “I want to create sculptures that make people take a look and 104 , ‘How can there be so much waste on the beach ’ The Washed Ashore sculptures, hopefully, will make people consider what they buy in their 105 life and realize how so much plastic ends up in the oceans.” So far, more than 10, 000 volunteers have 106 21 tons of waste and helped create more than 70 works of art. Four traveling exhibitions have shown the sculptures in more than 18 107 , including the National Zoological Park. One of Washed Ashore’s sculptures, Turtle Ocean, received a 108 honor. It was shown at the National Museum.
The Washed Ashore team is now working on sculptures of a dolphin, with 109 for more sculptures. “Until we run out of plastic on the beach, the work will continue.” Angela says 110 , “These sculptures are a call for clean oceans.”

From toothbrushes and shampoo bottles to furniture and toys, plastic is used to make many everyday items—but only about 5% of the plastic we use is recycled. The rest is 111 which releases harmful gases, or thrown away, often ending up in the ocean. There, it can take hundreds of years to break down and 112 marine life. To help solve this problem, scientists have created a new type of plastic that dissolves in seawater.
Regular biodegradable plastics do not fully break down in the ocean. 113 they turn into tiny pieces called microplastics. These small bits can be eaten by fish, birds, and other animals. Scientists 114 that by 2050, there may be more plastic in the ocean than fish. Microplastics also pollute soil, water, and food, eventually 115 human bodies.
Researchers at the RIKEN Centre for Emergent Matter Science in Japan have developed a plastic that dissolves 116 in salty seawater. It breaks down into its basic substances, which bacteria can then digest. Tests show it can break down in seawater within hours and in soil within 10 days. Unlike other plastics, it is nonpoisonous and does not catch fire 117 .
This new plastic can be shaped into different forms when 118 to 248°F. It can be made hard and scratch-resistant, turned into flexible rubber, or used to create strong objects. It could be 119 for 3D printing and making items like medical tools or single-use packaging.
Takuzo Aida, the lead researcher, said, “With this new material, we have created plastics that are strong, stable, and recyclable. They serve many purposes and, most importantly, do not 120 microplastics.”

The 121 came to them one day as they were walking home through the park. They noticed people had 122 lots of litter on the grass. They thought that the park looked really messy and 123 , so they wanted to make it clean.
Then they asked the local people to come and help them 124 all the litter in the park. They chose the first day of May 125 it’s a national holiday. It meant most people had much free time to help them. They offered litter bags and gloves to the 126 . And they also prepared some 127 and printed (打印) them out to put them up in their school and around the park. These posters would always remind people to be good citizens (市民).
On that day, more than 80 volunteers turned up to 128 litter in the park. Picking up litter was a(n) 129 job, and that would not take too much time, but everyone worked very carefully.

According to a study in Nature Climate Change, the number of polar bears will 131 rapidly (快速地) by 2080. There are two reasons. One is that the sea ice is melting (融化). Polar bears catch seals (海豹) to eat on the ice. 132 ice, they have to stay on land. But there is no 133 food on land to support so many polar bears. The animals could die of hunger. The other reason is that mother bears may not be 134 enough to produce milk for their babies, so some polar bears could stop having babies.
Polar bears are the 135 land animals that eat meat on the planet. They help control other kinds of animals. Losing them would break the balance of their living places.
The Arctic is 136 to about 25, 000 polar bears. Arctic sea ice usually melts in spring and summer, and then grows in winter. But now, the 137 is taking longer to grow back. Scientists say the Arctic is warming twice as fast as the rest of the planet.
The study also shows that it is possible to 138 Arctic sea ice melting. Greenhouse gases could lead to climate change. In order to avoid creating greenhouse gases, the world should try to stop burning coal and riding in cars.
Saving the bears is up to 139 . Holland, one of the writers of the study, says, “I believe there is hope, but humans need to act 140 to make that hope come true.” Let’s take action to protect our earth and save polar bears.
