【答案解析】[解析] 11-13
There are two main kinds of beer in pubs in the UK. One is called mild, and the other is known as bitter. Mild is a slightly sweeter brew than bitter, and the colour of mild is a deeper shade of brown. However, the difference is a result of two different brewing processes, or more specifically, the result of different ingredients being used in the brewing process.
In the case of mild, the brewing process involves the use of slightly roasted barley, whereas with the bitter brew the barley is not roasted. Furthermore, when bitter is undergoing preparation there is more use of a plant called hops, which give it its distinctive bitter taste.When bitter is ready for consumption, it is a light yellow colour, sometimes becoming a light brown. If the barley is more heavily roasted, the beer takes on an ever deeper shade, resulting eventually in a brew which is almost black.
One important point is that the names of mild and bitter do not necessarily indicate the relative strength of these two forms of beer.The word "bitter" may sound stronger than the word 'mild,' but in this case the opposite may be true; in other words, there are some mild beers which are stronger than bitter beers. The preference for one kind over another is of course a matter of personal choice, but it is true that more bitter beer is drunk in Britain than mild beer.The reason for this is not clear. It may simply be because more bitter beer is available than mild beer; on the other hand, it may be because bitter beer may be regarded somehow as a more exciting drink than mild beer Certainly it contains more acid, which is perhaps why the medical profession recommend that if you are going to drink beer regularly, you should ask for mild rather than bitter, because the lower acid content in the mild beer means that it is better for the health.This last point may be borne in mind whenever somebody raises their glass to you and says 'cheers', or'to your health'.
