Have you ever been to London? How much do you know about London? Now let me tell you.

London has a population of about 8.96 million. From about the year 1800 to 1945, London was the biggest city in the world. But now many cities are even bigger than before.

London is famous for many things. Tourists come from all over the world to visit its famous buildings and listen to the famous clock, Big Ben.

Like many big cities, London has problems, such as traffic and pollution, and they stop the city from developing. Every day about 1 million people come and go by underground, but there are still too many cars and buses in the streets. So the air isn’t clean. However, it is cleaner than it was 100 years ago.

For me, the best things in London are the parks. There are five parks in the city centre. But my children’s favourite place is Hamleys, the biggest toy shop in the world.

This year, COVID-19 broke out again in many places in China. Shanghai is one of the worst cities among them. To fight against COVID-19, Shanghai built many makeshift（临时的）hospitals in the city.

Inside a makeshift hospital, a group of 28 disinfection（消毒）robots were working busily. Each of them could work 24 hours a day without any rest.

At the same time, a group of 5G indoor multifunctional（多功能的）cloud robots were busy delivering food in the hospital. Each robot could send about 20 boxed meals at a time. They usually went to patients’ areas and waited for them to collect their food. “In the past, it usually took a worker about 20 minutes to send 20 boxed meals. Now the work can be completed in just 5 minutes with the help of these robots,” a patient said.

“The robots not only make our work much easier, but also help protect us from catching the disease（疾病）,” said a worker in the hospital.

To win the fight quickly, the local government also put more than 200 robots into use at a makeshift hospital. Outside those makeshift hospitals, more and more unmanned cars appeared on the streets to help people.

It is true that people with better education are usually able to get better-paid jobs. In other words, they have more chances to choose a good job while people with little or no education don’t. It seems that the purpose of education is to make people get jobs. But this isn’t accepted by all people.

Some people may think that a person should spend the best years of his life getting education only for a way of living. This is probably one of the earliest reasons of education. In fact, if education is just a way of making a living, people don’t need to spends much time in school. People can get education for a living in a short time. Subjects like history and geography need not be taught to everyone. Even language and mathematics need not be taught in a comprehensive (综合的) way, either. It is clear that education is much more than teaching a man to get a way of living.

Education is well-rounded and it is mainly for improving a man. It is not only to teach him to speak, read and write, but also to develop his creative thinking and other abilities. After that, it is to make him a wise man and thankfully enjoy the achievements of humans. Education is to make a man lead a better life. Educated people are expected to be able to listen to good music, read good books, watch plays and most of all take an interest in the world.

I would agree that making a good living is an important reason for education, but certainly not the most important or the main reason.
