听播客学英语 217 关于你的一切

 　　In this podcast I use words which are useful when we talk about numbers, especially when we want to talk about the information that numbers give us. The podcast is also about you, my listeners, because I know quite a lot about you.

　　How do I know about you? Well, to start with, my podcast software tells me how many times you download each podcast. You download most episodes¹ over 7000 times. The great majority (about 90%) of you download podcasts using iTunes or another podcatcher programme.

　　On the podcast website (http://www.listen-to-english.com/) there is a little button marked Site Meter. If you click it, you can find all sorts of interesting information about people who visit the site. For example, you will see that on average about 250 people visit the website each day, and that on average you spend over 6 minutes looking at the site. You will also see that on average visitors to the site view more than 1,000 pages each day, and that each visitor views an average of 4.3 pages.

　　If you click on “countries” at the bottom of the Site Meter screen, you will see a pie-chart, which shows the countries from which visitors come. You come from all over the world! On most days, there are more visitors from France than from any other country. If you click on “continents” you will see how many visitors are from Asia, how many from Europe and so on. On most days, slightly more than half of all visitors are from Europe. Click on “browser² share” to see which web browser programmes you use. The majority of you use Internet Explorer. About 25% of you use Firefox, and a small number of you (fewer than 10%) use other browsers³ such as Safari⁴ and Opera.

　　If you click on “daily visit depth” you will see a bar chart. It shows the average number of page views per visitor for each day in the last month. The number of page views varies between 3 and 5 page views per visitor.

　　Finally, if you click on “daily durations”, you will see a graph which shows how long on average visitors spend on the site, and how long on each page, for each day in the last month. The average visit length varies a lot, between 250 seconds and over 500 seconds. The average time spent looking at each page does not vary very much – it is about 90 seconds.

　　There is a grammar and vocabulary note, and a short exercise with answers, for this podcast. You won’t be able to see them on iTunes – you will need to go to the website to find them.
