Language changes all the time. New words and phrases appear and develop. The words and pronunciations used by young people in the UK can be very different to those used by adults. Living in a multicultural (多元文化的) society has an effect on language, especially on young people, whose friends are often from a mix of backgrounds. TV and music also have big influence on the language of the young. Often UK singers sing in American accents (口音) without realizing.

Young British people use lots of language that you usually can't find in most dictionaries. These informal words and expressions are known as ‘slang'. It is not possible to make a complete list of modern British slang. By the time the list was finished, it would be out of date! New words come and go like fashions. However, here are a few examples:

Ø Safe, sorted, sound, cool or wicked all mean "That's good" or "I understand".

Ø  Instead of using different tag questions like … isn't it? can't you? or don't they?,     people use innit.

Ø  Instead of saying very, really or completely, people use well.

Ø  Whatever means I don't care.

Ø ‘He's fine' or ‘He's fit' both mean ‘He's good-looking'. Fine and fit can describe a boy or a girl.

Not everybody uses slang and not everybody likes it. A school in Sheffield, in the north of England, recently stopped its pupils using slang words such as hiya (hello), cheers and ta (both mean thank you). The head teacher says that if young people learn to speak ‘correctly' this will help them get a place at university and a good job.

When British people use language like this, it's no surprise that some students say they can't understand native (本土的) speakers. But perhaps learners don't need to worry about communicating with native speakers so much. Research shows that most of the English spoken in the world today is spoken between non-native speakers of the language. In fact, when we think about "International English", there is no such thing as a native or non-native speaker.

How I have improved my English

English is very important.

Confidence(自信) is very important in our dairy life. It can help us to develop a healthy attitude(态度). A study shows that the people who are more confident are much happier. They can have more chances to make themselves successful.

But how to be more confident? Here are some suggestions:

Speak Loud. When you are not confident, you can't do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loud enough so that people can hear you clearly. The high voice can help you become more confident.

Play sports.Physical exercise makes you tired but completely relaxed. A strong body helps you be full of confidence.

Encourage yourself.Write down a list of things you did during the day to see how many things you have done well. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise(表扬) for the good things you have done. This is the best way to encourage yourself.

Pick up a hobby.If you like singing, sing as much as you can. In some ways, a hobby can make you understanding. And it will make you happy and confident.

①Google's company, DeepMind, recently announced that their research team has created a ping-pong robot. This robot can play at the same level as human amateur (业余) players.

②The research team wrote about their work on a website called arXiv. A team member said, "This is the first learning robot that can play ping-pong as well as human amateurs. " The robot has a six-axis robotic arm that can move back and forth and side to side on a rail at the bottom.

③In 29 games against human players, the robot won 13 times, which is a win rate of 45%. The human players were all new to the robot, and their skill levels ranged from beginners to advanced players. The researchers said, "The robot lost all the games against high-level players but won all the games against beginners and 55% of the games against intermediate players."

④To make the robot play at a human level, the team used a layered and modular strategy(分层和模块化的策略).This means the robot can do basic skills like forehand topspin and backhand blocks. It also has a high-level controller that acts like a brain. During a game, it can choose the best moves based on the game situation, the robot's abilities, and the opponent's skills. After the game, the robot can analyze (分析) the data and improve its skills.

⑤The researchers noted that the robot still has some weaknesses. For example, it is not very good at backhand shots and has trouble with fast, high, low, or strongly spinning balls. They plan to improve the robot by making better control algorithms(算法)and better hardware.
