2.6 Context and language variation

As well as contributing to meaning, context can also influence the actual words and sentences that we use. Do you sometimes say ‘Hi’ and at other times say ‘Good morning’? Do you have a ‘telephone voice’? This variation in language may be done deliberately, but often it is not. There are two main reasons as to why we adjust the way we speak:

  • to fit in with our audience or what we feel they expect of us; you may use ‘professional’ langu

1.11 Addition and subtraction in practice - fluid balance

A common healthcare example that uses addition and subtraction involves calculating the fluid balance of a patient.

Fluid balance is a simple but very useful way to estimate whether a patient is either becoming dehydrated or overfilled with liquids. It is calculated, on a daily basis, by adding up the total volume of liquid that has gone into their body (drinks, oral liquid medicines, intravenous drips, transfusions), then adding up the total volume of liquid that has come out of their

6.3 What is the main requirement for regional government? Is it a shared identity?

If we compare the UK with other Western democracies such as Spain, Italy or Germany – all endowed with decentralised structures allowing various degrees of political autonomy for their regions – we discover that strong regional identity, as in Catalonia, the Veneto and Bavaria, is always a very important feature. However, some newly created regions such as La Rioja and Madrid in Spain also exercise devolved powers. What unites them is a common interest; the belief that regional government

3.3.5 Third reading

This is the final vote on the Bill. It is almost a formality since a Bill which has passed through all the stages above is unlikely to fail at this late stage. In fact, in the House of Commons there will only be a further debate on the Bill if at least six MPs request it. In the House of Lords amendments may sometimes be made at this stage.

8.3 Shortage of minerals

You may be familiar with salt licks that are provided for domesticated cattle. In the wild, grass is also often low in minerals (e.g. it has almost no sodium and very little calcium), so grazers may have to go to extraordinary lengths to supplement their diet with additional minerals obtained from the most unlikely places. LoM gives some examples, but the most impressive activity takes place in the caves of Mount Elgon in Kenya [pp. 113-114]. You'll probably recall this spectacular footage fr

2.1.1 The morality play

Before looking at the play's opening scene I should add a brief note on the medieval morality play, the type of drama on which Marlowe draws in adapting The Damnable Life for the stage. After the Prologue and Faustus's long opening speech, you may have been startled by the appearance of the Good and Evil Angels. Even if you had expected to find supernatural beings in a play about a man who sells his soul to the devil, the Good and Evil Angels may have struck you as strange, perh
