Neil Hello. This is 6 Minute English from BBC Learning English. I'm Neil. Georgie And I'm Georgie. Neil If I told you I'd been for a walk to see Big Ben and Buckingham Palace, you'd know straight away I was in London. Georgie But what if my walk went past cafes selling mozzarella and ricotta where I smelled freshly made cannolis and focaccia... Where would I be then? Neil Focaccia and mozzarella... you'd be in Italy, right? Georgie Yes, Italy, or 'Little Italy' to be exact - the neighbourhood in some cities where Italian communities settled and made their home. Neil These Italian arrivals opened shops and cafes selling food to their own communities. Soon dishes like spaghetti and meatballs attracted the attention of local people, and gradually Italian food became famous around the world. In this programme, we'll be taking a walk through two Little Italys, one in Argentina, the other in New York, and, as usual, we'll be learning some useful new vocabulary as well. But before that, I have a question for you, Georgie. According to a recent YouGov poll, which Italian food is most popular with British diners? Is it: a) pizza? b) lasagne? or c) garlic bread? Georgie I think it must be pizza. Neil Okay, Georgie, I'll reveal the answer at the end of the programme. One country Italians moved to was Argentina. In 1898, Giuseppe Banchero arrived in the neighbourhood of La Boca, the Little Italy of Buenos Aires, where many Italian immigrants started restaurants. Here, Hugo Banchero, grandson of Giuseppe, tells his story to Veronica Smink, reporter for BBC World Service programme, The Food Chain: Hugo Banchero Well, my grandfather came from Italy, from Genoa, from Liguria. He was born in the centre of Genoa and arrived here in 1898 at the age of seven and a half, and this pizzeria where we are was founded on March 28, 1972. We have been here for 91 years. Veronica Smink So what culinary traditions did they bring with them? Hugo Banchero Well, our culinary tradition is pizza, and we incorporated the faina from Genoa, which is a pizza with chickpea flour... Georgie In 1898, Giuseppe founded his pizzeria - a restaurant selling pizza. When a business is founded, it's established someone starts it, or sets it up. Neil Giuseppe brought the culinary traditions from his home in Liguria in northern Italy, including regional pizzas like faina and fugazzetta. The adjective culinary describes anything connected with cooking. Georgie But probably the best-known Little Italy in the world is an area of Manhattan's Lower East side in New York. Ninety percent of Italian immigrants who arrived in the US at the turn of the century came through this neighbourhood. Neil De Palos, one of the original shops selling Italian food in Little Italy, has been serving customers for 113 years. Here, Lou De Palo, co-owner and great-grandson of the original owner, Salvino, explains more about his family history to BBC World Service programme, The Food Chain: Lou De Palo 1925... when my grandmother, Concetta, and my grandfather, Luigi, got married, they open their own shop... it's the shop we continue today being the fourth generation working alongside my sister, Maria, my brother, Sal, and our children, the fifth generation. Our business has expanded; expanded to present the full food culture of the 20 regions of Italy. Little Italy is the stepping stone of the Italian immigrant. This is where many of the Italians first came through Ellis Island, and then settled here, and then eventually moved into mainstream America throughout the rest of the country. Georgie Lou De Palo is the fourth generation of his family to run the shop, and his children will be the fifth. Phrases like fourth or fifth generation describe the children of people whose parents immigrated to a particular country.

Georgie Ella's network of volunteers sewing reusable sanitary pads grew, and to date the Pachamama Project has donated tens of thousands of period products to refugees fleeing conflict in Syria, Turkey and Lebanon, as well as women here in the UK. Beth Plus, the project is helping in other ways too. Despite affecting so many people, and being necessary for life itself, many cultures consider menstruation unclean or shameful, not a topic of polite conversation. But Ella thinks her project is giving refugees the confidence to talk about periods, as she told BBC World Service's, People Fixing the World: Ella Lambert I have seen such major change in such a short short period of time. Like, the women originally who were distributing the pads would barely even speak about it and we had it behind a curtain, and now they'll chat away about the pads with their male colleagues, anyone that comes into the shop... Georgie ほとんどない Before, most women refugees would barely talk about menstruation, they would only just, scarcely talk about it. But now they're happily chatting away, passing the time talking to other women, and even to male colleagues.

Note: This is not a word-for-word transcript. Neil Hello. This is 6 Minute English from BBC Learning English. I'm Neil. Beth And I'm Beth. Neil Shhh! Quiet please! I'm trying to read here, Beth! Beth Oh, excuse me! I didn't know this was a library. Neil Well, what exactly is a library? Have you ever thought about that? Beth Well, somewhere with lots of books I suppose, where you go to read or study. Neil A symbol of knowledge and learning, a place to keep warm in the winter, or somewhere to murder victims in a crime novel: libraries can be all of these things, and more. Beth In this programme, we'll be looking into the hidden life of the library, including one of the most famous, the Great Library of Alexandria, founded in ancient Egypt in around 285 BCE. And as usual, we'll be learning some useful new vocabulary, and doing it all in a whisper so as not to disturb anyone! Neil Glad to hear it! But before we get out our library cards, I have a question for you, Beth. Founded in 1973 in central London, the British Library is one of the largest libraries in the world, containing around 200 million books. But which of the following can be found on its shelves. Is it: a) the earliest known printing of the Bible? b) the first edition of The Times' newspaper from 1788? or, c) the original manuscripts of the Harry Potter books? Beth I'II guess it's the first edition of the famous British newspaper, 'The Times'. Neil OK, Beth, I'll reveal the answer at the end of the programme. Libraries mean different things to different people, so who better to ask than someone who has written the book on it, literally. Professor Andrew Pettegree is the author of a new book, 'A Fragile History of the Library'. Here he explains what a library means to him to BBC Radio 3 programme, Art & Ideas: Andrew Pettegree Well, in my view, a library is any collection of books which is deliberately put together by its owner or patron. So, in the 15th century a library can be 30 manuscripts painfully put together during the course of a lifetime, or it can be two shelves of paperbacks in your home. Beth Andrew defines a library as any collection of books someone has intentionally built up. This could be as simple as a few paperbacks, cheap books with a cover made of thick paper.
