Last Saturday, David was taking a walk in the park near his home when he noticed a woman with a boy of about eight years old. When David passed them, he heard the woman yell. “How stupid you are! You’re good at nothing.” David stopped and looked at the little boy. The boy said nothing. He just stood there, looking upset.

David was reminded of his English teacher Mrs Brown in middle school. After he entered a middle school, David lacked self-confidence because he was often made fun of by others. He was often told that he was good at nothing, which David behaved. But one day it all changed.

One day, in an English writing class, Mrs Brown asked them to read a novel. They were asked to write a new chapter of the novel after they finished reading it. A few days later, David handed in his story. He didn’t give it much thought. But the next day, to his surprise, the comment “well done” from Mrs Brown came into view the moment he turned to the page where the story was written. When David read that, he almost burst into tears. He never expected to be praised one day. He suddenly gained some self-confidence.

That day after he returned home, he wrote a short story and gave it to Mrs Brown the next morning. And again he was praised. David became very interested in writing. He often wrote short stories and asked Mrs Brown to read them improve writing skills. One year later, David joined the school newspaper and became an editor of it. He was no longer that boy who lacked self-confidence. He gained his confidence, and was hopeful about his future.

He succeeded in entering a college and kept writing. Several years after graduating from college, he had his first book published. With some more books coming out, he became famous as a writer in his country. And he owed his success to Mrs Brown’s encouragement. Without her encouragement, his life might be very different now.

Inspired by his own life story, David decided to do something for that boy.

The mother was ashamed when she heard that.

Rising up in the countryside of Jiangxi Province, Mount Lushan was once one of the famous cultural     1     (center) of ancient China. In fact, its historical importance meant that it     2     (honor) as a World Heritage Site by UNESCO in 1996.

Located about 20 kilometres south of Jiujiang City, it runs eastwards to the Mufu Mountains. Dahanyang Peak, the highest peak of Mount Lushan,     3     (rise) 1, 474 metres above sea level. To the north, it offers    4     (impress) views of the Yangtze River, while to, the south it overlooks Poyang Lake.

As early as the Eastern Han Dynasty, a well-known Taoist leader,     5     (name) Zhang Daoling travelled to the mountain. During the Jin Dynasty, the Donglin Temple was built on the mountain by a person called Huiyuan. From then on, many temples began coming up across the mountain, until there were over 300 of them.

However, Mount Lushan didn’t become truly famous until the Song Dynasty. During that time, it was rebuilt by Zhu Xi,    6    was the founder of Neo-Confucianism (理学). Due    7     his efforts, this place became one of the Four Great Academies of China. By the 19th century, it had become into an     8     (extreme) large place, with its own temples, study halls, and libraries. Overtime, countless writers and artists have sung the mountain’s praises,    9     (leave) over 900 works of art.

Nowadays, with its beautiful l views and famous temples, the mountain range is     10     popular tourist attraction.

Yours sincerely,

9 . Being able to take advantage of truly unlimited data is a smartphone user’s dream, but everyone I’ve talked to about 5G is more excited about the usage unlocked by next-generation wireless devices. From smart home security to self-driving cars, all the Internet-connected equipment in your life will be able to talk to each other at lightning-fast speed with reduced delay.

“5G is one of those forerunners, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. Self-driving vehicles are emblematic in this data age — they show application of data completely. With one single task, driving, you have large amounts of data coming from the vehicle itself, and a variety of sensors (传感器) are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about conditions down the road. There’s lots of data behind that task, which is why we need the speed and lower latency (延迟).

AR glasses and virtual (虚拟的) reality headphones haven’t yet been inside the mainstream, but tech companies are joyfully saying that such equipment will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to improve — or even replace — smartphones.

Ericsson showed at February’s Mobile World Congress in 2019 how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on outside equipment for processing power.

But don’t get too excited. There’s still a lot of work to be done in the meantime, including some necessary testing to make sure the radio plays nicely with basic systems and service construction so that 5G isn’t concentrated only in big cities.
