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.

We heard that you are the first Head Teacher with a business background, so we hope your experience will help our school. I would like to express one concern about the change you are proposing to the after-school activity schedule. I realise that saving energy is important and from now it will be getting darker earlier. Is this why you have made the schedule an hour and a half shorter? Students at St Mark's School take both their studies and their after-school activities very seriously. A number of students have told me that they want to stay at school until 6.00 pm as they have always done. Therefore, I would like to ask you to think again about this sudden change in policy.

年度 英語 15 [II] Write (VI) opinions. Write your answer in about 100 English words, not counting punctuation marks. Mr. John Spence's opinion on e-bikes My electric bike is one year old on Thursday, and it was a 75th birthday present. I have only ever been a casual cyclist, but had given my old bike away, as my creaky knees combined with living at the top of a hill-meant that I rarely used it. But with my e-bike I feel so empowered. It is so easy to get around to do a few errands that it often seems quicker than using a car and having to find parking. If anyone is tempted by the idea, I strongly recommend giving it a try. Ms. Liz Ormond's opinion on e-bikes Mr. Spence's enthusiastic praise for e-bikes omits any reference to pedestrians. There is no mention that they are more dangerous than other bikes. Can he tell us what 19 OC DE BESLOT ACAI BESI TE OF 0.8. safety studies have been done in relation to pedestrians, particularly in shared space, and what discussions have been held with organisations such as the Royal National Institute of Blind People? Also, since the motors are effective enough to propel bikes loaded with shopping and children, what effect would the additional weight have in a collision with a pedestrian? (Adapted from "Wheels of fortune: the pros and cons of e-bikes," The Guardian, May 19,2020)
