Take for example, 不错 bùcuò, which means not bad. Since 错 is fourth tone, we read it as búcuò.

Nuit de fête
Le soleil du matin se lève sur la clairière; les invités dorment à poings fermés. Charlotte et Monsieur Hibou ont partagé le gâteau et le dévorent avec délice.
- Quelle belle fête et quel délicieux gâteau! déclare Charlotte, ravie.
Monsieur Sanglier s'éveille en grognant et observe les deux gourmands.
- Charlotte, dit-il, je vous souhaite de vivre très longtemps. Mais je me demande combien de nuits et de jours il faudra compter pour fêter votre centième anniversaire.

Attraverso temi legati alla cultura e alla società italiana, questo podcast vuole avvicinare gli stranieri alla lingua non solo da un punto di vista strettamente linguistico, ma soprattutto culturale. In questo episodio vi parlerò di Sanremo e del gioco che fa letteralmente impazzire l'Italia per tutta la durata del festival.

Intercultural communication. It sounds normal, right? But the relationship between culture and communication is a bit unclear for some. What was first? The egg or the chicken? The culture or the communication?

One way to improve our language skills is by expressing our thoughts in the target language. For that reason, I have prepared an English conversation class “Express Yourself through A Conversation”. Please feel free to check that lesson here: https://www.italki.com/en/teacher/24647106/english
I have a lot of interesting topics to talk about. But of course, you are welcome to bring up your own topic.

In this episode, I want to show you one example of the discussion topic. It’s about my imaginary city, Subara City 素晴市 （スバラしsu ba ra shi）.   The name is derived from 素晴らしい（すばらしい）and 都市（とし）.   素晴らしい means “wonderful”, “magnificent”.    市 means “city” and when placed at the end of a word can be pronounced as “shi”し.   So here I name my imaginary city 素晴市（スバラしsu ba ra shi）or “Subara City”.  In this episode, I’m introducing English lessons, not Japanese. I just want to let you know how I made up the name.

The theme of the story is that you have just been elected to the council for Subara City. You have 6 billion Yen in your budget. What can you do? Listen through. Below here is a simple worksheet to give you more ideas.
